Тем временем финансирование другой миссии - Solar Probe Plus - под вопросом: http://www.spacenews.com/article/civil-space/38604budget-heat-prompts-call-for-revising-nasa%E2%80%99s-heliophysics-roadmap
Meanwhile, NASA expects to find out this spring how much one of the biggest science missions on the agency's plate, Solar Probe Plus, will cost to build and launch. Preliminary estimates range fr om $1.2 billion to $1.4 billion and assume a July 2018 launch. The spacecraft's preliminary design review (PDR) is slated for January with a confirmation review to follow in March.
"Solar probe plus is the big swinger in our future plans," Chenette said. "This is the mission that will fly to less than 10 solar radii. Next year is important. Right now its in PDR season for instruments. There will be a spacecraft PDR in January. Shortly thereafter is Key Decision Point C wh ere we will establish cost, schedule and [the] plan for completing Solar Probe Plus. Getting that right is really important to the future of heliophysics. We have to make a plan to accomplish it within the budget [and then] carry out that plan."

Solar Probe Plus Moves into Advanced Development

March 18, 2014

(http://www.jhuapl.edu/newscenter/pressreleases/2014/images/140318_1_sm.jpg)

Technicians at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., prepare an engineering model of the Solar Probe Plus Thermal Protection System, or TPS, for vibration tests in October 2013. The main feature of the TPS is an 8-foot-diameter, 4.5-inch-thick, carbon-carbon, carbon foam shield that will sit atop the Solar Probe Plus spacecraft body. The system will protect Solar Probe Plus fr om temperatures exceeding 2,500 degrees Fahrenheit and impacts from hypervelocity dust particles as it flies through the sun's outer atmosphere. The vibration tests simulate the shaking the spacecraft will undergo during launch; Solar Probe Plus is scheduled to launch in 2018.

Solar Probe Plus -- NASA's ambitious mission to fly through and examine the sun's atmosphere -- has reached a key stage of development.

Solar Probe Plus will begin advanced design, development and testing -- a step NASA designates as Phase C -- following a successful design review in which an independent assessment board deemed that the mission team, led by the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., was ready to move ahead with full-scale spacecraft fabrication, assembly, integration and testing.

"Solar Probe Plus will fly closer to the sun than any spacecraft before it -- almost 10 times closer to the sun than the planet Mercury -- and this presents unprecedented technical challenges," says Andrew Driesman, Solar Probe Plus project manager at APL. "Whether it was devising ways for a spacecraft to survive so close to the sun, or to collect data in such an extreme environment, the concept of an operational solar probe had challenged engineers and scientists for decades, and now we're another step closer to making it happen."

Set to launch in 2018, Solar Probe Plus will orbit the sun 24 times, closing in with the help of seven Venus flybys. At its closest passes the probe will speed 118 miles per second through the sun's outer atmosphere, or corona, coming about 3.8 million miles (about 6.2 million kilometers) from the surface to explore a region -- and face hazards -- no other spacecraft has encountered. Solar Probe Plus will carry 10 science instruments specifically designed to help solve two key puzzles of solar physics: why the sun's outer atmosphere is so much hotter than the sun's visible surface, and what accelerates the solar wind that affects Earth and our solar system.

"The answers to these questions can be obtained only through in-situ measurements of the solar wind down in the corona," says APL's Nicky Fox, Solar Probe Plus project scientist. "Solar Probe Plus gets close enough to provide the missing links, with the right complement of instruments to make the measurements. For the first time, we will be able to go up and touch our star."

APL, which manages the mission and leads the spacecraft fabrication and integration effort, has made significant progress on several enabling technologies, such as the carbon-carbon composite heat shield that will protect Solar Probe Plus from temperatures exceeding 2,500 degrees Fahrenheit and impacts from hypervelocity dust particles. Engineers have also built and tested a liquid-cooling system to keep the spacecraft's solar arrays at safe operating temperature throughout the voyage, and spacecraft parts are undergoing high-velocity dust tests that simulate flights through swarms of high-energy particles near the sun.

"Solar Probe Plus is a pathfinder for voyages to other stars and will explore one of the last unexplored regions of the solar system, the solar corona, wh ere space weather is born," says Lika Guhathakurta, Solar Probe Plus program scientist at NASA Headquarters in Washington.

The Solar Probe Plus team includes engineers, scientists, technicians and other experts from government, academia and industry. The mission is part of NASA's Living With a Star program, designed to learn more about the sun and its effects on planetary systems and human activities. NASA's Goddard Space Flight Center in Greenbelt, Md., manages the program for the Science Mission Directorate at NASA Headquarters.

Цитатаhttp://www.spacenews.com/article/civil-space/41380solar-probe-plus-nasa's-'mission-to-the-fires-of-hell'-trading-atlas-5-for

GREENBELT, Md. -- Solar Probe Plus, a flagship heliophysics mission NASA expects to cost some $1.5 billion to build and launch around July 2018, needs a bigger rocket than United Launch Alliance's Atlas 5, according to a senior official at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, where the solar observatory is being built. 
"The plan we had was to go on an Atlas 5, but the problem is that required us to develop a new, high-performance custom upper stage, and that represented a fairly significant risk for the project," Michael Ryschkewitsch, head of APL's Space Sector, said in a July 22 interview here. "Our team made the case to NASA headquarters that the overall risk to the mission would be lowered if we went to a heavy-class launch vehicle. The obvious players right now are Delta 4 Heavy and Falcon Heavy."
"The decision to allow the consideration of a Heavy-class vehicle for Solar Probe Plus was made by the Science Mission Directorate in the spring of 2014 based on input from the Project and advice from Launch Services," James Norman, NASA's director of launch services, said July 25 via email. He declined to comment on why NASA cleared the program to procure a bigger launch vehicle, saying "the specifics associated with the decision are procurement sensitive and competition sensitive data."
Trading up to a Delta 4 Heavy or Falcon Heavy means the money paid to ATK Missile Products of Beltsville, Maryland, for work on the customized kick-stage motor, known as STAR 48GXV, was a wasted effort for Solar Probe Plus. APL spokesman Michael Buckley said July 23 that ATK was paid $15.7 million for the work, which culminated with a December test firing of the solid-fueled STAR motor. 
The flight-proven Delta 4 Heavy is Denver-based ULA's most powerful launcher, typically used for the largest classified national security satellites. Falcon Heavy, which is still in development at SpaceX, features a first stage composed of three nine-engine Falcon 9 core stages.
Falcon Heavy's first launch is planned for 2015. SpaceX advertises the rocket as the most powerful launcher since the Saturn 5, able to lift 53 metric tons to low Earth orbit at one-third the cost of a Delta 4 Heavy.

ЦитатаNASA has selected the United Launch Alliance (ULA) to loft its Solar Probe Plus (SPP) mission to study the Sun's outer atmosphere. The July, 2018 launch will utilize ULA's Delta IV Heavy rocket, augmented by Orbital ATK's Star-48 solid motor as a third stage, in order to cope with the extremely high energy required for this flagship mission.

To achieve its goals, SPP will orbit the sun 24 times, closing to within 3.9 million miles of its surface with the help of seven Venus flybys.

At its closest passes the probe will speed 118 miles per second through the sun's outer atmosphere, or corona, to explore a region - and face hazards - no other spacecraft has encountered.


ULA beat out other launch providers to win the right to launch the mission - citing a competitive procurement that considered multiple companies. NASA's Launch Services Program (LSP), managing the campaign, announcing the total contract award amount for launch services is $389.1 million.

"The ULA team is very proud that NASA has selected the Delta IV Heavy launch vehicle for this extraordinary science mission," noted Jim Sponnick, ULA vice president, Atlas and Delta Programs.

Due to the high energy requirements for this mission, a third stage will top off the propulsive elements. This will be in the form of Orbital ATK's Star-48 solid rocket motor.

Ну вот. А George негодовал, что Дельта-4 Хэви не запустила ничего выдающегося :)

NASA Gives Green Light for Johns Hopkins APL to Begin Building Solar Probe Plus Spacecraft
http://www.nasa.gov/content/goddard/nasa-gives-green-light-for-johns-hopkins-apl-to-begin-building-solar-probe-plus-spacecraft/

ЦитатаNASA's Solar Probe Plus mission -- which will fly closer to the sun than any spacecraft has before -- reached a major milestone last month when it successfully completed its Critical Design Review, or CDR.

An independent NASA review board met at the Johns Hopkins University Applied Physics Laboratory, or APL, in Laurel, Maryland, March 16-20, 2015, to review all aspects of the mission plan. APL has designed and will build and operate the spacecraft for NASA. The CDR certifies that the Solar Probe Plus mission design is at an advanced stage and that fabrication, assembly, integration and testing of the many elements of the mission may proceed.

Solar Probe Plus is scheduled to launch aboard a United Launch Alliance Delta 4-Heavy rocket with an upper stage from Cape Canaveral Air Force Station, Florida. The launch window opens for 20 days starting on July 31, 2018. Over 24 orbits, the mission will use seven flybys of Venus to reduce its distance from the sun. The closest three will be just 3.8 million miles from the surface of the star.

Scientists have long wanted to send a probe through the sun's outer atmosphere, or corona, to better understand the solar wind and the material it carries into our solar system. The primary science goals for the Solar Probe Plus mission are to trace the flow of energy and understand the heating of the solar corona and to explore the physical mechanisms that accelerate the solar wind and energetic particles.

To meet those objectives, Solar Probe Plus will carry four instrument suites into the corona and study the solar wind and energetic particles as they blast off the surface of the star. These instruments will study magnetic fields, plasma, and energetic particles, and will image the solar wind. The instruments are: the Fields Experiment from the University of California Space Sciences Laboratory, Berkeley, California; the Integrated Science Investigation of the Sun from the Southwest Research Institute, San Antonio; the Solar Wind Electrons Alphas and Protons Investigation from the Smithsonian Astrophysical Observatory, Cambridge, Massachusetts; and the Wide Field Imager for Solar Probe Plus from the Naval Research Laboratory, Washington, D.C.

The spacecraft and instruments will be protected from the sun's heat by a 4.5-inch-thick carbon-composite shield. During the closest passes around the sun, temperatures outside the spacecraft will reach nearly 2,500 degrees Fahrenheit.
Solar Probe Plus is part of NASA's Living With a Star Program to explore aspects of the connected sun-Earth system that directly affect life and society. LWS is managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland, for NASA's Science Mission Directorate in Washington.

Solar Probe Plus Mission Moves into Advanced Development

NASA's first mission to "touch" the sun has passed a critical development milestone that keeps it well on track toward its scheduled summer 2018 launch.

Following a successful NASA management review on July 7, the Solar Probe Plus mission -- which will send a spacecraft on several daring data-collecting runs through the sun's atmosphere -- is moving into the system assembly, integration, test and launch stage of the project. NASA terms this period as Phase D, during which the mission team will finish building the spacecraft, install its science instruments, test it under simulated launch and space conditions, and launch it.

"Reaching this stage means a lot to the team and our stakeholders," said Andy Driesman, Solar Probe Plus project manager at the Johns Hopkins Applied Physics Laboratory (APL), which manages the mission for NASA and is building the spacecraft. "It shows we've designed a spacecraft, instruments and a mission that can address the engineering challenges associated with the harsh solar environment, and send back the data that scientists have sought for decades. It's humbling to see designs and ideas start to become a spacecraft." (https://testforum.novosti-kosmonavtiki.ru/forum/file/64377)

Engineers at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, prepare the developing Solar Probe Plus spacecraft for thermal vacuum tests that simulate conditions in space. Today the spacecraft includes the primary structure and its propulsion system; still to be installed over the next several months are critical systems such as power, communications and thermal protection, as well as science instruments. The probe is scheduled for launch in summer 2018. Credit: NASA/JHUAPL.

Solar Probe Plus is set to launch during a 20-day window that opens July 31, 2018. Over 24 orbits, the spacecraft will use seven flybys of Venus to reduce its distance fr om the sun. The closest three orbits will be within 3.9 million miles of the sun's surface -- roughly seven times closer than any spacecraft has come to our star -- wh ere it will face solar intensity more than 500 times what spacecraft experience while orbiting Earth.

This mission of extreme exploration will provide new data on solar activity and contribute significantly to our ability to forecast major space-weather events that impact life on Earth. The primary science goals for Solar Probe Plus are to trace the flow of energy from and understand the heating of the sun's outer atmosphere -- its corona -- and to explore the physical mechanisms that accelerate the solar wind, the continuous stream of charged and energetic particles flowing out from the sun. To do that requires sending a probe through the corona to better understand the solar wind and the material it carries into our solar system. It's been a goal of scientists for nearly 60 years, one that is only possible today through cutting-edge thermal engineering advances.

Solar Probe Plus will carry four instrument suites designed to study magnetic fields, plasma and energetic particles, and image the solar wind. The spacecraft and instruments will be protected from the sun's heat by a 4.5-inch-thick carbon-composite shield, which will need to withstand temperatures that reach nearly 2,500 degrees Fahrenheit -- but keep the spacecraft's payload operating at room temperature.

Solar Probe Plus is part of NASA's Living With a Star program to explore aspects of the sun-Earth system that directly affect life and society. LWS is managed by the agency's Goddard Space Flight Center in Greenbelt, Maryland, for NASA's Science Mission Directorate in Washington, D.C. APL, in Laurel, Maryland, manages the mission for NASA and is designing and building and will operate the spacecraft.

Солнечный зонд обретает форму

Весной прошлого года я рассказывал про миссию Solar Probe Plus (SPP). Это спутник для изучения солнечной короны. Он должен войти в историю как аппарат, который приблизится к нашему светилу на рекордно малое расстояние. И пока что у миссии все идет хорошо.

Недавно SPP прошел важный этап. Инженеры из университета имени Джона Хопкинса в Мериленде завершили монтаж корпуса и двигателей аппарата и сейчас приступают к фазе D: установке научных инструментов, теплозащиты, систем связи и проведению предполетных испытаний.

Окно для запуска SPP откроется 31 июля 2018 года. Чтобы вплотную подобраться к Солнцу, аппарат будет использовать гравитацию Венеры. В период с 2018 по 2024 год зонд семь раз пройдет рядом с планетой. С каждым пролетом перигелий его орбиты будет уменьшаться. Во время последних трех орбит в 2024 году SPP будет приближаться к Солнцу на минимальное расстояние 5.9 миллионов километров, проходя через внешние слои его короны. Чтобы миссия удалась, теплозащитному экрану аппарата придется как следует потрудиться. При минимальном сближении теплозащитный щит аппарата будет раскаляться до температуры в 1500 градусов.

At International Meeting, Mission Team Previews the Science of Solar Probe Plus
Posted on 01/05/2017 13:41:46 | Views: 286

The science of Solar Probe Plus - NASA's first mission to "touch" the sun - was on stage last month at the American Geophysical Union's Fall Meeting in San Francisco.

With some 25,000 attendees, representing nearly 100 countries, AGU's Fall Meeting is the world's largest Earth and space science conference. Solar Probe Plus team members took full advantage of the large audience with presentations and posters on mission science, as well as a multimedia "flash talk" from Project Scientist Nicky Fox at the NASA exhibit.

 (https://testforum.novosti-kosmonavtiki.ru/forum/file/68455)

"Not only was this meeting a chance for us to excite people about the launch - which is now less than two years away - but it was also a wonderful opportunity to exchange ideas with colleagues and have serious conversations about how what we learn from Solar Probe Plus will revolutionize our understanding of the sun," said Fox, a scientist at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland.

Set to launch in July 2018, Solar Probe Plus will provide new data on solar activity and make critical contributions to our ability to forecast major space-weather events that impact life on Earth. The spacecraft will actually plunge several times through the sun's atmosphere, facing brutal heat and radiation conditions - and ultimately providing humanity with the first ever close-up view of a star.

Decked Out: Solar Array Cooling System Coming Together on Solar Probe Plus

Posted on 04/19/2017 13:58:23

The Solar Array Cooling System on Solar Probe Plus has one critical job - to protect the NASA spacecraft's solar arrays from incineration as it moves through the blazing atmosphere of the sun.

Several key elements of that system are now on board the spacecraft, installed last week during ongoing integration and test operations at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland. On April 5, engineers carefully attached the deck that holds the solar array cooling system components, solar array cooling system radiators and the truss structure assembly, or TSA. The TSA will support the spacecraft's signature 8-foot-wide, 4.5-inch-thick carbon-carbon foam heat shield, as well components from the FIELDS experiment and Solar Wind Electrons, Alphas and Protons (SWEAP) suite that will make direct measurements of the charged particles and electrical fields in the solar environment.

Tuning Up: Solar Probe Plus Gets its First Science Instrument
Posted on 05/17/2017 07:32

With a few electrical connections and several turns of a wrench, Solar Probe Plus had its first onboard scientific instrument. The EPI-Lo particle detector - half of the Integrated Science Investigation of the Sun instrument suite - was installed on the spacecraft on April 17 at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.

"With EPI-Lo on board - our first scientific instrument - we can begin to call Solar Probe Plus an 'observatory,'" said Andrew Driesman, Solar Probe Plus project manager from APL. "We are looking forward to the integration of the other instruments on the spacecraft, subsequent testing, on-orbit science operations and ultimately new discoveries."

Designed and built by the APL - which also designed and is building the Solar Probe Plus spacecraft - EPI-Lo will measure low-energy particles streaming from the sun. Combining EPI-Lo data with the high-energy particle measurements of its EPI-Hi component, the entire suite will explore the mechanisms that produce, accelerate and transport energetic particles in the inner heliosphere - which stretches from the Sun's corona to the orbit of Mercury.

"Measuring the energetic particles near the sun, and flying an entire suite of instruments on such a Solar Probe is an exciting event in science almost 60 years in the making," said Ralph McNutt, the EPI-Lo lead from APL. "This type of instrument has also been decades in the making at APL, and is the next extension for such time-of-flight plus energy instruments, which orbited Mercury on MESSENGER, flew by Pluto on New Horizons, and are currently circling the Earth on the Van Allen Probes and Jupiter on the Juno mission. All of these instruments came from the leadership of Don Mitchell in instrument concepts and design and through the teamwork of a gifted set of scientists, engineers, programmers and managers at APL."

David McComas of Princeton University is the Integrated Science Investigation of the Sun (IS¤IS) principal investigator, and the Southwest Research Institute, San Antonio, manages the IS¤IS suite. NASA's Jet Propulsion Laboratory is providing the EPI-Hi instrument, scheduled for integration later this week.

Solar Probe Plus will carry three other scientific instruments and suites: a solar wind plasma suite, the Solar Wind Electrons Alphas and Protons (SWEAP) investigation; an electric and magnetic field suite known as FIELDS; and a wide-field imager called WISPR. This state-of-the-art payload - riding aboard a probe that will fly closer to the sun than any spacecraft before it - will address the mission's overarching science goal: to determine the structure and dynamics of the sun's coronal magnetic field, understand how the solar corona and wind are heated and accelerated, and determine what mechanisms accelerate and transport energetic particles.

Solar Probe Plus is scheduled to launch during a 20-day window that opens July 31, 2018.

ВАШИНГТОН, 26 мая - РИА Новости. НАСА планирует летом 2018 года запустить космический исследовательский зонд, которому предстоит приблизиться к Солнцу на рекордно близкое расстояние, сообщило ведомство в пятницу.
"Запуск миссии Solar Probe Plus (SPP) запланирован на лето 2018", -- сообщает НАСА. Предварительно сообщается, что старт зонда запланирован на период между 31 июля и 19 августа на ракете-носителе Delta IV-Heavy.
Аппарат достигнет расстояния 3,9 миллиона миль (6,2 миллиона километров) над поверхностью Солнца, приблизившись к звезде ближе, чем Меркурий. По утверждению НАСА, аппарат первым "потрогает" Солнце, поскольку будет в семь раз ближе к нему, чем другой когда-либо отправлявшийся к этой звезде человеком зонд.
В ведомстве сообщают, что SPP "будет исследовать внешнюю атмосферу звезды и вести крайне важные наблюдения, которые ответят на существующие десятилетиями вопросы о ее физических характеристиках".
В НАСА рассчитывают, что результаты исследований "улучшат прогнозы о том, как крупные явления в космической погоде влияют на Землю, спутники и (работу) астронавтов в космосе". Основная миссия зонда рассчитана на 11 дней, ее подробности будут обнародованы на следующей неделе.

ВАШИНГТОН, 31 мая. /Корр. ТАСС Дмитрий Кирсанов/. Национальное управление США по аэронавтике и исследованию космического пространства (NASA) приняло решение назвать отправляемую к Солнцу автоматическую межпланетную станцию в честь американского астрофизика Юджина Паркера.

Первооткрыватели, рекордсмены, космонавты, астронавты и туристы -- мы собрали информацию обо всех, кто когда-либо совершал космические полеты
Об этом сообщил на торжественной церемонии в Университете Чикаго (штат Иллинойс), посвященной официальному объявлению о предстоящей отправке упомянутого зонда к Солнцу, руководитель научного директората NASA Томас Цурбухэн.
В состоявшемся мероприятии принял участие и 90-летний Паркер, который до сих пор ведет научную деятельность в Университете Чикаго. Паркер одним из первых специалистов в мире занимался исследованием солнечного ветра. С 1967 года он является членом Национальной академии наук США. Предполагается, что зонд Паркера подлетит в семь раз ближе к Солнцу, чем какой-либо другой из космических аппаратов, ранее отправлявшихся человеком.
Запуск станции состоится в промежутке между 31 июля и 19 августа 2018 года. Планируется, что зонд в ноябре будущего года приблизится к Солнцу на расстояние в 6,4 млн км. Это означает, что аппарат будет находиться в пределах короны Солнца, то есть внешних слоев его атмосферы, где температура может достигать 500 тыс. кельвинов (около 500 тыс. градусов по Цельсию) и даже нескольких миллионов кельвинов.
По замыслу американских ученых, в период по июнь 2025 года зонд совершит 24 витка по орбите вокруг Солнца, разгоняясь до скорости 724 тыс. км в час. На каждый такой виток у него будет уходить 88 дней.
На борту аппарата стоимостью порядка $1,5 млрд будет находиться четыре комплекта научных инструментов. При помощи этой аппаратуры специалисты рассчитывают, в частности, осуществить различные измерения солнечной радиации. Кроме того, зонд должен будет передать фотоснимки, которые станут первыми, сделанными в пределах солнечной короны. Оборудование зонда будет защищено оболочкой из углепластика толщиной 11,43 см, позволяющей выдержать температуру до примерно 1,4 тыс. градусов по Цельсию.
NASA обещает, что миссия произведет революцию в представлении человека о процессах, протекающих на Солнце. Претворение в жизнь намеченных планов позволит внести "фундаментальный вклад" в понимание причин "нагревания солнечной короны", а также возникновения солнечного ветра (потока ионизированных частиц, истекающего из солнечной короны) и "ответить на критически важные вопросы в гелиофизике, которые уже на протяжении нескольких десятилетий имеют высший приоритет", убеждено NASA. Как оно подчеркнуло, информация с борта аппарата будет иметь огромную ценность и с точки зрения подготовки дальнейших пилотируемых полетов за пределы Земли, поскольку позволит прогнозировать "радиационную обстановку, в которой предстоит работать и жить будущим покорителям космоса".

Cool Power

Posted on 06/21/2017 09:00:23 | Views: 845

As NASA's Parker Solar Probe spacecraft begins its first historic encounter with the sun's corona in late 2018--flying closer to our star than any other mission in history--a revolutionary cooling system will keep its solar arrays at peak performance, even in extremely hostile conditions.

Every instrument and system on board Parker Solar Probe (with the exception of four antennas and a special particle detector) will be hidden from the sun behind a breakthrough thermal protection system (TPS)--an eight-foot diameter shield that the spacecraft uses to defend itself against the intense heat and energy of our star.

Every system will be protected, that is, except for the two solar arrays that power the spacecraft. When the spacecraft is closest to the sun, the solar arrays will be receiving 25 times the solar energy they would while orbiting Earth, and the temperature on the TPS will reach more than 2,500F (1,370C). The cooling system will keep the arrays at a nominal temperature of 320F (160C) or below.

"Our solar arrays are going to operate in an extreme environment that other missions have never operated in before," said the Johns Hopkins Applied Physics Lab's Mary Kae Lockwood, spacecraft system engineer for Parker Solar Probe.



New Innovations to Survive the Inferno

The very outermost edges of the solar arrays are bent upward, and when the spacecraft is closest to the sun, these small slivers of array will be extended beyond the protection of the TPS in order to produce enough power for the spacecraft's systems.

The incredible heat of our star would damage conventional spacecraft arrays. So, like many other technological advances created especially for this mission, a first-of-its-kind actively cooled solar array system was developed by APL, in partnership with United Technologies Aerospace Systems (UTAS) in Windsor Locks, Connecticut (which manufactured the cooling system) and SolAero Technologies of Albuquerque, New Mexico (which produces the solar arrays).

"This is all new," Lockwood said of the innovations related to the actively cooled solar array system. "NASA funded a program for Parker Solar Probe that included technology development of the solar arrays and their cooling system. We worked closely with our partners at UTAS and SolAero to develop these new capabilities, and we came up with a very effective system."

http://parkersolarprobe.jhuapl.edu/News-Center/admin/Press-Releases/images/articles/sacs-at-gsfc_tvac-3273.jpg

The Parker Solar Probe cooling system has several components: a heated accumulator tank that will hold the water during launch ("If water was in the system, it would freeze," Lockwood said); two-speed pumps; and four radiators made of titanium tubes (which won't corrode) and sporting aluminum fins just two hundredths of an inch thick. As with all power on the spacecraft, the cooling system is powered by the solar arrays--the very arrays it needs to keep cool to ensure its operation. At nominal operating capacity, the system provides 6,000 watts of cooling capacity--enough to cool an average-sized living room.

Somewhat surprisingly, the coolant used is nothing more than regular pressurized water--approximately five liters, deionized to remove minerals that could contaminate or harm the system. Analysis showed that, during the mission, the coolant would need to operate between 50F (10C) and 257F (125C)--and few liquids can handle those ranges like water. "Part of the NASA technology demonstration funding was used by APL and our partners at UTAS to survey a variety of coolants," said Lockwood. "But for the temperature range we required, and for the mass constraints, water was the solution." The water will be pressurized, which will raise its boiling point above 257F.

The solar arrays feature their own technical innovations. "We learned a lot about solar array performance from the [APL-built] MESSENGER spacecraft, which was the first to study Mercury," said Lockwood. "In particular, we learned how to design a panel that would mitigate degradation from ultraviolet light."

The cover glass on top of the photovoltaic cells is standard, but the way the heat is transferred from the cells into the substrate of the panel, the platen, is unique. A special ceramic carrier was created and soldered to the bottom of each cell, and then attached to the platen with a specially-chosen thermally conductive adhesive to allow the best thermal conduction into the system while providing the needed electrical insulation.



From Ice to Fire: Launch Challenges

While the extraordinary heat of the sun will be the spacecraft's most intense challenge, the minutes immediately following launch are actually one of the spacecraft's most critical early performance sequences.

When Parker Solar Probe launches on board a ULA Delta IV Heavy rocket from Cape Canaveral Air Force Station, Florida, in the summer of 2018, the cooling system will undergo wide temperature swings. "There's a lot to do to make sure the water doesn't freeze," said Lockwood.

First, temperatures of the solar arrays and cooling system radiators will drop from that in the fairing (about 60F, or 15C) to temperatures ranging from -85F to -220F (-65C to -140C) before they can be warmed by the sun. The pre-heated coolant tank will keep the water from freezing; the specially designed radiators--designed to reject heat and intense temperatures at the sun--will also survive this bitter cold, thanks to a new bonding process and design innovations.

Less than 60 minutes later, the spacecraft will separate from the launch vehicle, and begin the post separation sequence. It will rotate itself to point at the sun; the solar arrays will release from their launch locks; the arrays will rotate to point to the sun; a latch valve will open to release the warm water into two of the four radiators and the solar arrays; the pump will turn on; the spacecraft will rotate back to a nominal pointing orientation, warming up the two coldest and unactivated radiators; and power from the cooled solar arrays will begin recharging the battery.

In another first, this complex and critical series of tasks will be completed autonomously by the spacecraft, without any input from mission control.

The water for the two unactivated radiators will remain in the storage tank for the first 40 days of flight; after that, the final two radiators will be activated.

"One of the biggest challenges in testing this is those transitions from very cold to very hot in a short period of time," Lockwood said. "But those tests, and other tests to show how the system works when under a fully-heated TPS, correlated quite well to our models."

Thanks to testing and modeling, the team studied data and increased the thermal blanketing on the first two radiators to be activated, in order to balance maximizing their capacity at the end of the mission, and further reduce the risk of water freezing early in the mission.



Keeping Cool, Autonomously

When Parker Solar Probe is hurtling past the sun at some 450,000 miles an hour (724,000 KPH), it will be 90 million miles from mission controllers on Earth--too far for the team to "drive" the spacecraft. This means that adjustments to how the spacecraft is protecting itself with the TPS need to be handled by Parker Solar Probe's onboard guidance and control systems. These systems use new and effective autonomous software to allow the spacecraft to instantly alter its pointing to maximize protection from the sun. This autonomous capability is critical to the operation of the spacecraft's solar arrays, which must be constantly adjusted for optimal angle as Parker Solar Probe hurdles through the sun's harsh, superheated corona.

"During solar encounters, very small changes in the wing angle of the solar array can vastly change cooling capacity needed." Lockwood said that a one degree change in the array angle of one wing would require 35 percent more cooling capacity.

The constant challenge is to make sure the spacecraft and the arrays are staying cool.

"There's no way to make these adjustments from the ground, which means it has to guide itself," Lockwood said. "APL developed a variety of systems--including wing angle control, guidance and control, electrical power system, avionics, fault management, autonomy, and flight software--that are critical parts working with the solar array cooling system."

Added Lockwood: "This spacecraft probably is one of the most autonomous systems ever flown."

That autonomy, along with the new cooling system and pioneering solar array upgrades, will be crucial to ensuring that Parker Solar Probe can perform the never-before-possible science investigations at the sun that will answer questions scientists have had about our star and its corona.

From NASA: Delta IV Heavy Booster Cores Arrive for Parker Solar Probe
Posted on 08/03/2017 11:56:00 | Views: 91

Launch preparations are beginning to get off the ground for NASA's upcoming Parker Solar Probe mission, scheduled to lift off in summer 2018 atop a United Launch Alliance Delta IV Heavy rocket.

Two of the three common booster cores comprising the rocket's first stage have arrived on the company's Mariner ship, which delivered the components to Port Canaveral in Florida. From there the cores were offloaded and transported to the Horizontal Processing Facility at Cape Canaveral Air Force Station's Space Launch Complex 37.

The Parker Solar Probe will perform the closest-ever observations of a star when it travels through the Sun's atmosphere, called the corona. The probe will rely on measurements and imaging to revolutionize our understanding of the corona and the Sun-Earth connection.

ЦитатаNASA в 2018 году запустит зонд для исследования Солнца
НЬЮ-ЙОРК, 20 сентября. /Корр. ТАСС Игорь Борисенко/. Национальное управление по аэронавтике и исследованию космического пространства (NASA) летом будущего года намерено запустить специальный зонд для исследования Солнца. Автоматическая станция Parker Solar Probe по расчетам должна пройти примерно в 6,4 млн км от поверхности звезды, то есть примерно в семь раз ближе, чем аппарат Helios 2, приближавшийся к Солнцу в 1972 году на расстояние в 43,2 млн км. Станция окажется ближе к Солнцу, чем Меркурий - ближайшая планета Солнечной системы.
"Данные, собранные в ходе этого полета, обеспечат поистине революционные изменения в наших представлениях о Солнце, - сообщило в пресс-релизе NASA. - Автоматическая станция пройдет через атмосферу Солнца и приблизится к его поверхности ближе, чем любой другой аппарат, обеспечив человечеству возможность наблюдения за Солнцем с самой близкой дистанции".
Как сообщила во вторник газета The New York Times (https://www.nytimes.com/), от испепеляющего жара солнечной короны - около 1300 градусов Цельсия - станция будет защищена специальным композитным покрытием толщиной 11,43 см. Такая защита обеспечит нормальное функционирование аппаратуры, предназначенной для изучения солнечной короны и солнечного ветра - постоянного потока заряженных частиц, испускаемого Солнцем, а также для изучения магнитных полей, плазмы и заряженных частиц. Наблюдения автоматической станции позволят более точно прогнозировать "космическую погоду" в окрестностях Земли.

In this time-lapse video taken on Sept. 21, 2017, the thermal protection system - the heat shield -- for NASA's Parker Solar Probe spacecraft is shown during installation at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. This 4.5-inch thick, eight-foot diameter shield protects the spacecraft and its instruments against the intense heat and energy of the Sun's outer atmosphere, the corona, through which the spacecraft will fly on a mission of extreme exploration. The thermal protection system is made of a carbon-carbon composite material with a special outer coating that will reach temperatures of nearly 2,500 degrees Fahrenheit. The heat shield was placed on the probe for a test of alignment as part of integration and testing, but it will soon be removed. Both spacecraft and shield will continue separate testing processes and then be re-integrated just before launch in summer 2018.

Parker Solar Probe Gets Its Revolutionary Heat Shield

On Sept. 25, 2017, media were invited to see NASA's Parker Solar Probe in its flight configuration at Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, where it is being built. The revolutionary heat shield that will protect the first spacecraft to fly directly into the Sun's atmosphere was installed for the first time on Sept. 21. This is the only time the spacecraft will have its thermal protection system -- which will reach temperatures of 2,500 degrees F while at the Sun -- attached until just before launch.

Parker Solar Probe Gets Visit Fr om Namesake

Eugene N. Parker, professor emeritus at the University of Chicago, today visited the spacecraft that bears his name: NASA's Parker Solar Probe. This is the first NASA mission that has been named for a living researcher, and is humanity's first mission to the Sun.
Parker proposed the existence of the constant outflow of solar material fr om the sun, which is now called the solar wind, and theorized other fundamental stellar science processes. On Oct. 3, 2017, he viewed the spacecraft in a clean room at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, where the probe was designed and is being built. He discussed the revolutionary heat shield and instruments with the Parker Solar Probe team and learned how the spacecraft will answer some of the crucial questions Parker identified about how stars work.

NASA's Parker Solar Probe is scheduled for launch on July 31, 2018, fr om Cape Canaveral Air Force Station, Florida. The spacecraft will explore the Sun's outer atmosphere and make critical observations that will answer decades-old questions about the physics of stars. The resulting data will also improve forecasts of major eruptions on the sun and subsequent space weather events that impact life on Earth, as well as satellites and astronauts in space.

Parker Solar Probe Successfully Completes Pre-Environmental Testing Review (http://parkersolarprobe.jhuapl.edu/News-Center/Show-Article.php?articleID=49)

ЦитатаNASA's Parker Solar Probe, the first mission to fly into the Sun's corona, has successfully completed a review that approves the beginning of the spacecraft's environmental testing.

A review panel of engineers fr om NASA and the Johns Hopkins Applied Physics Laboratory, where the spacecraft was designed and is being built, declared on September 29 that Parker Solar Probe has passed required performance tests and can move into environmental testing.

For Parker Solar Probe, this means the probe will be subjected to a series of challenging simulations of launch and space operations that will ensure the spacecraft is up to the difficult task of exploring the extreme environment of the Sun's atmosphere - the corona. The spacecraft will first be bolted to a vibration table at APL, which will simulate the violent physical forces of launch; Parker Solar Probe will be lifted skyward on a Delta IV-Heavy launch vehicle, the largest in the world currently in operation. The spacecraft has already completed mass properties testing, which is important for mating to the launch vehicle and for maneuvering and attitude control.

In early November, the spacecraft will travel a short distance to the NASA Goddard Space Flight Center in Greenbelt, Maryland, wh ere it will be subjected to acoustic, thermal cycling, and vacuum testing that will make sure the probe can withstand the sound generated at launch and the dramatic swings of hot and cold that it will be subjected to following launch from Cape Canaveral Air Force Station, Florida, in summer 2018.

"It's a testament to the hard work and diligence of the Parker Solar Probe team that we successfully completed our review, and we're excited to move forward into environmental testing," said Andy Driesman of APL, the Parker Solar Probe project manager. "We're looking forward to completing these tests, and then heading to Florida to begin the preparations for next year's launch."

NASA's Parker Solar Probe spacecraft will explore the Sun's outer atmosphere and make critical observations that will answer decades-old questions about the physics of stars. The resulting data will also improve forecasts of major eruptions on the sun and subsequent space weather events that impact life on Earth, as well as satellites and astronauts in space. The mission is named for Eugene N. Parker, whose profound insights into solar physics and processes have guided the discipline.

To ensure that NASA's Parker Solar Probe will be able to withstand the physical stresses of launch, engineers at the Johns Hopkins Applied Physics Laboratory - where the probe was designed and is being integrated and tested - used a special device called a shaker table to simulate the forces of being hurled into space. The spacecraft successfully passed vibration testing, or "vibe," as the engineers call it, in late October.
"Our vibration testing uses our 40,000-pound force shaker to simulate many of the dynamic events that occur during launch and powered flight," said APL's Dave Persons, Parker Solar Probe lead structural engineer. "By safely simulating that process here in the clean room, we're able to fully monitor the spacecraft and make sure it's cleared for flight. During the test, we actively monitored over 300 channels of data."

During and after launch aboard a Delta IV Heavy--the world's largest launch vehicle--from Cape Canaveral Air Force Station, Florida, in summer 2018, Parker Solar Probe will undergo immense shaking and vibration. These Earth-bound tests are designed to make sure all of the systems and instruments on the spacecraft are up to those stresses.

"The predicted responses for major loading events - derived from studying and analyzing how payloads like spacecraft that are attached to the launch vehicle behave - establishes just how much force and vibration that Parker Solar Probe will be subjected to," said Shelly Conkey of APL, Parker Solar Probe structural analyst. "We load that information into our simulation, and the shaker table subjects the probe to that force and vibration. This testing lets us know that the probe is adequately designed to survive launch, and is ready to move on to further environmental testing, which we'll continue at NASA's Goddard Space Flight Center."

The Parker Solar Probe spacecraft will explore the Sun's outer atmosphere and make critical observations that will answer decades-old questions about the physics of stars. The resulting data will also improve forecasts of major eruptions on the sun and subsequent space weather events that impact life on Earth, as well as satellites and astronauts in space. The mission is named for Eugene N. Parker, whose profound insights into solar physics and processes have guided the discipline.

Sound Effects: Parker Solar Probe Passes Acoustic Testing

When NASA's Parker Solar Probe lifts off on top of a Delta IV Heavy launch vehicle in summer 2018, it will undergo both intense vibration fr om the physical forces of the rocket engines, as well as acoustic effects from the sound of the engines and the rocket going through the atmosphere.

Verifying the spacecraft and its systems are ready for the rigors of launch is one of the most important parts of testing. On Nov. 3, Parker Solar Probe passed vibration testing at the Johns Hopkins Applied Physics Laboratory, or APL, in Laurel, Maryland, wh ere it was designed and built. On Nov. 14, the spacecraft successfully completed acoustic testing at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and is now being prepared for further environmental tests.
Goddard's Acoustic Test Chamber is a 42-foot-tall chamber that uses 6-foot-tall speakers -which can create sound levels of up to 150 decibels - to simulate the extreme noise levels of a rocket launch. While vibration testing focuses on how much the spacecraft will shake during launch, acoustic testing subjects the probe to intense sound forces, like those generated by the Delta IV Heavy. Each type of force affects the spacecraft differently, so both tests are necessary.

"We're launching on a very large and powerful vehicle, so we need to make sure that the spacecraft, its systems, and its instruments are going survive the launch environment," said Shelly Conkey, a Parker Solar Probe structural analyst at APL, who led the acoustic test. "We use our data models to predict the forces that will be impacting Parker Solar Probe, and by comprehensive monitoring of the spacecraft during testing, we can ensure that we're ready to move on to thermal vacuum testing."

Parker Solar Probe spacecraft will explore the Sun's outer atmosphere and make critical observations that will answer decades-old questions about the physics of stars. The resulting data will also help improve how we forecast major eruptions on the Sun and subsequent space weather events that can impact life on Earth, as well as satellites and astronauts in space. The mission is named for Eugene N. Parker, whose profound insights into solar physics and processes have helped shape the field of heliophysics.

Purple Gaze: Parker Solar Probe's Solar Arrays Pass Laser Illumination Testing

NASA's Parker Solar Probe passed laser illumination testing the week of Nov. 27, 2017. During this test, each segment of the spacecraft's solar panels was illuminated with lasers to check that they were still electrically connected after the vigorous vibration and acoustic testing completed earlier this fall.

Parker Solar Probe is in the midst of intense environmental testing at NASA's Goddard Space Flight Center in Greenbelt, Maryland, in preparation for its journey to the Sun. These tests have simulated the noise and shaking the spacecraft will experience during its launch from Cape Canaveral, Florida, scheduled for July 31, 2018.

Parker Solar Probe's integration and testing team must check over the spacecraft and systems to make sure everything is still in optimal working condition after experiencing these rigorous conditions - including a check of the solar arrays, which will provide electrical power to the spacecraft.

"This illumination testing verifies that each 'string' of solar cells on the array remains electrically connected to the spacecraft after vibration and acoustic testing," said solar array lead engineer Ed Gaddy of the Johns Hopkins Applied Physics Lab, or APL, in Laurel, Maryland. APL is building and will operate the spacecraft.

To make sure that the 44 strings -- a series of connected solar cells -- on each panel are still well-connected after environmental tests, each string was illuminated individually to ensure that they would still create electricity and transfer it to the spacecraft. Lasers are ideal for this kind of testing, because their narrow beam allows the team to illuminate just one string at a time. The strikingly colored lasers were selected because they were readily available and because the solar cells operate efficiently at that color. But by themselves, these visible lasers are insufficient to power the solar cells, so the team also used infrared lasers for this test. Infrared light is not visible to our eyes and wasn't captured in these images.

To protect NASA's Parker Solar Probe from the intense heat of the Sun's atmosphere, scientists and engineers developed a revolutionary Thermal Protection System. This heat shield, made of carbon-carbon composite material, will experience temperatures of almost 2,500 degrees Fahrenheit as the spacecraft hurtles through the solar atmosphere, while keeping the instruments on the spacecraft at approximately room temperature.

The heat shield recently moved from the Johns Hopkins Applied Physics Lab, or APL, in Laurel, Maryland, to NASA's Goddard Space Flight Center in Greenbelt to undergo testing in NASA Goddard's large Thermal Vacuum Chamber. The Thermal Vacuum Chamber will simulate the harsh conditions that the heat shield must endure during the mission: This includes the airless vacuum of space along with huge temperature fluctuations between hot and cold as the spacecraft swings past the Sun and back out into space. The Thermal Protection System's ability to withstand extreme temperatures has already been proven through testing at other facilities, as the Thermal Vacuum Chamber at NASA Goddard cannot simulate the very high temperatures of the Sun.

On Wednesday, Jan. 17, NASA's Parker Solar Probe was lowered into the 40-foot-tall thermal vacuum chamber at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The spacecraft will remain in the chamber for about seven weeks, coming out in mid-March for final tests and packing before heading to Florida. Parker Solar Probe is scheduled to launch fr om NASA's Kennedy Space Center on July 31, 2018, on a Delta IV Heavy launch vehicle.

The thermal vacuum chamber simulates the harsh conditions that Parker Solar Probe will experience on its journey through space, including near-vacuum conditions and severe hot and cold temperatures.

"This is the final major environmental test for the spacecraft, and we're looking forward to this milestone," said Annette Dolbow, Parker Solar Probe's integration and test lead from the Johns Hopkins Applied Physics Lab. "The results we'll get from subjecting the probe to the extreme temperatures and conditions in the chamber, while operating our systems, will let us know that we're ready for the next phase of our mission - and for launch."

During thermal balance testing, the spacecraft will be cooled to -292 degrees Fahrenheit. Engineers will then gradually raise the spacecraft's temperature to test the thermal control of the probe at various set points and with various power configurations.

Next, thermal cycling testing will transition the spacecraft from cold to hot and back again several times, simulating the conditions it will experience many times during its mission to the Sun. The Parker Solar Probe team will also test operation of the spacecraft's hardware at both hot and cold plateaus, as well as perform a mission simulation.

On Saturday, Jan. 27, NASA's Parker Solar Probe began space environment testing, starting with the air being pumped out of the 40-foot-tall thermal vacuum chamber at NASA's Goddard Space Flight Center in Greenbelt, Maryland where the spacecraft is currently housed. The chamber - officially called the Space Environment Simulator - creates a nearly identical replication of the conditions the spacecraft will face during its mission to the Sun.
After the air was slowly removed from the chamber over the course of five hours, cooling tubes behind the chamber walls were chilled to -320 degrees Fahrenheit (-196 Celsius).

Engineers will cycle the chamber's temperatures from hot to cold to ensure Parker Solar Probe will be prepared for operations around the Sun. During this cycling, the spacecraft's systems will undergo testing that mimics critical events that occur during its planned seven-year mission in space. The tests are designed to make sure all the systems and components of Parker Solar Probe are operating as designed.

07.03.2018НАСА собирает имена желающих отправиться в "полет к Солнцу"
Зонд Parker Solar Probe, запуск которого состоится в конце июля этого года, отправится на рандеву с Солнцем в компании с табличкой, на которой будут записаны имена любых добровольцев, желающих помочь ему раскрыть тайны жизни светила, сообщает НАСА.
"Наш зонд можно в самом прямом смысле назвать самой быстрой, горячей и крутой миссией на свете. Этот удивительный космический корабль поможет нам раскрыть огромное количество тайн Солнца и понять, как работают его недра, что раньше нам никак не удавалось узнать", -- заявила Никола Фокс (Nicola Fox), научный руководитель миссии из университета Джона Гопкинса в Балтиморе (США).
По текущим планам научной команды миссии, PSP пролетит через корону светила 24 раза, постепенно сближаясь с поверхностью Солнца. Для того, чтобы зонд не сгорел во время первого такого рандеву, он оборудован огромным тепловым экраном из специального углепластикового материала, отражающего 99% света и тепла, чья толщина составляет 11 сантиметров, а длина и ширина - несколько метров.
Несмотря на столь внушительную защиту, корпус зонд будет разогреваться до температур, составляющих примерно 1500 градусов Кельвина, и подвергаться действию мощного потока радиации, превышающего фон на Земле почти в 500 раз.
Как и при отправке многих других миссий, НАСА прикрепит к корпусу Parker Solar Probe миниатюрный кремниевый чип, на чьей поверхности будут выгравированы имена всех людей, пожелавших отправиться вместе с зондом в путешествие к поверхности Солнца. Для этого нужно заполнить анкету на сайте космического агентства до конца апреля этого года, передает РИА Новости.

Since January, Parker Solar Probe underwent a series of tests inside NASA Goddard's large thermal vacuum chamber - officially called the Space Environment Simulator - that mimicked the conditions the spacecraft will face in space throughout its seven-year mission. After initially testing the spacecraft's functions under hot and cold extremes, engineers have spent the past month slowly cycling the temperatures in the thermal vacuum chamber back and forth between hot and cold, making sure Parker Solar Probe's systems and components operate properly. This thermal cycling is similar to the conditions the spacecraft will experience as it completes 24 close approaches to the Sun over its seven-year mission.

"Successfully completing this final round of space environment testing is critical, and the team has created an exceptional spacecraft," said Andy Driesman, Parker Solar Probe program manager from the Johns Hopkins Applied Physics Lab in Laurel, Maryland, which designed, built, and will manage the mission for NASA. "We now know the spacecraft and systems are able to operate in space, and that Parker Solar Probe is ready to embark on this historic mission."

ЦитатаАмериканский зонд для исследования Солнца доставлен к космодрому на мысе Канаверал
ВАШИНГТОН, 7 апреля. /Корр. ТАСС Дмитрий Кирсанов/. Американская автоматическая межпланетная станция, предназначенная для исследования Солнца, переброшена к космодрому на мысе Канаверал (штат Флорида), с которого она должна стартовать уже летом. Об этом сообщило в пятницу Национальное управление США по аэронавтике и исследованию космического пространства (NASA).
Последние приготовления
В ночь со 2 на 3 апреля зонд был перевезен из входящего в структуру NASA Центра космических полетов имени Годдарда в Гринбелте (штат Мэриленд) на расположенную поблизости базу ВВС и ВМС США Эндрюс. Оттуда аппарат на борту военно-транспортного самолета C-17 доставили утром во вторник на сборочное предприятие компании Astrotech Space Operations, соседствующее с космодромом на мысе Канаверал. В среду зонд извлекли из контейнера, в котором он перебрасывался из Мэриленда во Флориду.
На объекте фирмы Astrotech Space Operations у космодрома на мысе Канаверал станция, по свидетельству сотрудников NASA, пройдет в оставшиеся до старта месяцы последние всеобъемлющие испытания.
Кроме того, там ее "упакуют" в специальное термозащитное покрытие, а затем заправят топливом, укроют носовым обтекателем и установят на тяжелую ракету-носитель Delta IV. На днях на космодроме на мысе Канаверал уже состыковали первую и вторую ступень той ракеты, которой и предстоит вывести зонд в космос.
Стартовое окно открывается 31 июля, а закрывается 19 августа.
В условиях, "приближенных к боевым"
С января на протяжении почти двух месяцев станцию подвергали температурным испытаниях в вакууме. Эти тесты шли в Центре имени Годдарда, где зонд, который по размерам сопоставим с небольшим автомобилем, поместили в вакуумную камеру высотой примерно 12 м.
Инженеры сначала проверяли, выдерживают ли зонд и его "начинка" низкую температуру - до минус 292 градусов Фаренгейта (минус 180 Цельсия). Затем ее постепенно увеличивали, чтобы посмотреть, как на станцию воздействует экстремально высокая температура. Потом специалисты чередовали такой перепад температур, имитируя условия полета в космическом пространстве.
Детали миссии
Планируется, что в ноябре зонд приблизится к Солнцу на расстояние в 6,4 млн км. Это означает, что аппарат будет находиться в пределах короны Солнца, то есть внешних слоев его атмосферы, где температура может достигать 500 тыс. кельвинов (около 500 тыс. градусов по Цельсию) и даже нескольких миллионов кельвинов.
По замыслу американских ученых, в период по июнь 2025 года зонд совершит 24 витка по орбите вокруг Солнца, разгоняясь до скорости 724 тыс. км в час. На каждый такой виток у него будет уходить 88 дней.
На борту аппарата стоимостью порядка $1,5 млрд будет находиться четыре комплекта научных инструментов. При помощи этой аппаратуры специалисты рассчитывают, в частности, осуществить различные измерения солнечной радиации. Наряду с этим зонд должен будет передать фотоснимки, которые станут первыми, сделанными в пределах солнечной короны. Оборудование зонда будет защищено оболочкой из углепластика толщиной 11,43 см, позволяющей выдержать температуру до примерно 1,4 тыс. градусов по Цельсию.
Как признала в июне прошлого года координатор проекта Никола Фокс, его удалось реализовать только теперь благодаря появлению новых материалов, использованных в первую очередь при создании термостойкого щита зонда. Станция получит и новые панели солнечных батарей, уточнила Фокс. "Мы наконец прикоснемся к Солнцу", - сказала специалист. По ее выражению, зонд поможет ученым понять, "как работает Солнце".
Значение проекта
NASA обещает, что миссия произведет революцию в представлении человека о процессах, протекающих на Солнце. Претворение в жизнь намеченных планов позволит внести "фундаментальный вклад" в понимание причин "нагревания солнечной короны", а также возникновения солнечного ветра (потока ионизированных частиц, истекающего из солнечной короны) и "ответить на критически важные вопросы в гелиофизике, которые уже на протяжении нескольких десятилетий имеют высший приоритет", убеждено NASA. Информация с борта аппарата, по мнению его специалистов, будет иметь огромную ценность и с точки зрения подготовки дальнейших пилотируемых полетов за пределы Земли, поскольку позволит прогнозировать "радиационную обстановку, в которой предстоит работать и жить будущим покорителям космоса".
Зонд назван в честь выдающегося американского астрофизика Юджина Паркера, которому минувшим летом исполнилось 90 лет. Несмотря на почтенный возраст, он до сих пор ведет научную деятельность в Университете Чикаго (штат Иллинойс).
Паркер стал одним из первых в мире специалистов, занимавшихся исследованиями солнечного ветра. С 1967 года он является членом Национальной академии наук США.
Предполагается, что зонд Паркера подлетит в семь раз ближе к Солнцу, чем какой-либо другой из космических аппаратов, ранее отправлявшихся человеком.

In the middle of the night on April 2, the spacecraft was driven from NASA's Goddard Space Flight Center in Greenbelt, Maryland, to nearby Joint Base Andrews in Maryland. From there, it was flown by the United States Air Force's 436th Airlift Wing to Space Coast Regional Airport in Titusville, Florida, wh ere it arrived at 10:40 a.m. EDT. It was then transported a short distance to Astrotech Space Operations, also in Titusville, wh ere it will continue testing, and eventually undergo final assembly and mating to the third stage of the Delta IV Heavy launch vehicle.

Parker Solar Probe is humanity's first mission to the Sun. After launch, it will orbit directly through the solar atmosphere - the corona - closer to the surface than any human-made object has ever gone. While facing brutal heat and radiation, the mission will reveal fundamental science behind what drives the solar wind, the constant outpouring of material from the Sun that shapes planetary atmospheres and affects space weather near Earth.

"Parker Solar Probe and the team received a smooth ride from the Air Force C-17 crew from the 436th," said Andy Driesman, Parker Solar Probe project manager from the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. "This is the second most important flight Parker Solar Probe will make, and we're excited to be safely in Florida and continuing pre-launch work on the spacecraft."

At Astrotech, Parker Solar Probe was taken to a clean room and removed from its protective shipping container on Wednesday, April 4. The spacecraft then began a series of tests to verify that it had safely made the journey to Florida. For the next several months, the spacecraft will undergo comprehensive testing; just prior to being fueled, one of the most critical elements of the spacecraft, the thermal protection system (TPS), or heat shield, will be installed. The TPS is the breakthrough technology that will allow Parker Solar Probe to survive the temperatures in the Sun's corona, just 3.8 million miles from the surface of our star.

"There are many milestones to come for Parker Solar Probe and the amazing team of men and women who have worked so diligently to make this mission a reality," said Driesman. "The installation of the TPS will be our final major step before encapsulation and integration onto the launch vehicle."

Parker Solar Probe will be launched from Launch Complex-37 at NASA's Kennedy Space Center, Florida. The two-hour launch window opens at approximately 4 a.m. EDT on July 31, 2018, and is repeated each day (at slightly earlier times) through Aug. 19.

Throughout its seven-year mission, Parker Solar Probe will explore the Sun's outer atmosphere and make critical observations to answer decades-old questions about the physics of stars. Its data will also be useful in improving forecasts of major eruptions on the Sun and the subsequent space weather events that impact technology on Earth, as well as satellites and astronauts in space. The mission is named for University of Chicago Professor Emeritus Eugene N. Parker, whose profound insights into solar physics and processes have guided the discipline. It is the first NASA mission named for a living individual.

The Thermal Protection System -- also known as the heat shield -- for NASA's Parker Solar Probe arrived in Titusville, Florida, on April 18, 2018, bringing it one step closer to reuniting with the spacecraft that will be the first to "touch" the Sun.

The Parker Solar Probe spacecraft arrived at Astrotech Space Operations two weeks prior, on April 3, to complete final testing. Though the spacecraft was flown by the Air Force's 436th Airlift Wing, the Thermal Protection System, or TPS, traveled on a flatbed truck, securely encased in a metal shipping container during its road trip to the Sunshine State. After setting off on a rainy Monday morning fr om Maryland, it was greeted with Florida's balmy heat on Wednesday afternoon at Astrotech, where it will eventually be reattached to the spacecraft before launch in late July.

The innovative TPS will be the one barrier shielding the spacecraft and its instruments from the intense heat of the Sun. Made of carbon-carbon composite and stretching approximately eight feet wide, the TPS will withstand temperatures of up to 2,500 degrees Fahrenheit while keeping the spacecraft and instruments at a comparatively comfortable 85 degrees Fahrenheit. The heat shield has a plasma-sprayed white surface that will reflect the intense heat energy of the Sun's corona away from the spacecraft.

On the morning of Tuesday, April 17, 2018, crews from United Launch Alliance raised the 170-foot tall Delta IV Heavy launch vehicle - the largest and most powerful rocket currently used by NASA - at Launch Complex 37 at Cape Canaveral Air Force Station in Florida. This Delta IV Heavy will carry Parker Solar Probe, humanity's first mission to the Sun's corona, on its journey to explore the Sun's atmosphere and the solar wind. Launch is scheduled for approximately 4 a.m. EDT on July 31, 2018.
The launch vehicle consists of three Common Booster Cores, with a second stage on the center core; the encapsulated spacecraft, is scheduled to arrive in early July for integration onto the rocket. The spacecraft is now at Astrotech Space Operations in nearby Titusville undergoing final integration and testing. Parker Solar Probe will be the fastest human-made object in the solar system, traveling at speeds of up to 430,000 miles per hour (700,000 kilometers per hour).

Gearing up for a predawn blastoff July 31, launch crews have positioned a Delta 4-Heavy rocket in the starting blocks on a seaside launch complex at Cape Canaveral as engineers inside a tightly-controlled clean room a few miles away put the final touches on a NASA probe that will travel closer to the sun than any mission before.
The mission's key components were on the move earlier this month, with the Parker Solar Probe's shipment fr om the Johns Hopkins Applied Physics Laboratory to Florida's Space Coast on April 3. After arriving in Florida aboard a U.S. Air Force cargo plane, the spacecraft was trucked to a clean room at the Astrotech Space Operations payload processing facility in Titusville.

Meanwhile, technicians inside the Delta 4 rocket's assembled the launcher's three first stage booster cores since their arrival fr om United Launch Alliance's factory in Decatur, Alabama, on two shipments aboard the company's Mariner rocket transport ship last July and August. Workers connected the Delta 4-Heavy's upper stage in early March, then transferred the launcher to Cape Canaveral's Complex 37B launch pad April 16.

Hydraulic lifts hoisted the rocket vertical inside the launch pad's mobile gantry April 17, beginning checkouts that will include several launch day rehearsals, including a fueling test, in the coming months.

Liftoff is scheduled for July 31 during a two-hour launch window that opens at approximately 4:15 a.m. EDT (0815 GMT).

Named for Eugene Parker, the scientist who predicted in 1958 the influence of the solar wind, the Parker Solar Probe will fly closer to the sun than any past mission, reaching a point in December 2024 as close as 3.8 million miles -- less than 6.2 million kilometers -- from the sun's visible surface, also known as the photosphere.

The Helios 2 spacecraft, a joint project by NASA and the German space agency, is the current record-holder. It flew 27 million miles -- 43.4 million kilometers -- from the sun in April 1976.

That record will be shattered early in Parker Solar Probe's mission. With the help of a big boost from the Delta 4-Heavy rocket, the most powerful launcher currently certified to carry NASA missions into space, and an extra impulse from a solid-fueled Star 48BV upper stage provided by Orbital ATK, the 1,500-pound (685-kilogram) Parker Solar Probe will reach Venus on Sept. 28 for a flyby that will use the planet's gravity to redirect the spacecraft's orbit inside the orbit of Mercury.

The big rocket, upper stage and repeated encounters with Venus are required to nudge Parker Solar Probe closer to the sun, effectively slowing the spacecraft from its initial 18-mile-perscond speed -- relatively to the sun -- at Earth's orbit to allow solar gravity to pull it closer.

"Since we're going so close to the sun, we have to lose a lot of energy, a lot of angular momentum, associated with the Earth's orbit," said Jim Kinnison, Parker Solar Probe's mission system engineer, in an interview with Spaceflight Now. "To do that, we need a really big rocket that can provide us with a high (escape velocity). The Delta 4-Heavy was the best we could get, but even that wasn't sufficient. We still need a third stage to provide even more of a boost for us. The third stage will do that, but we're also targeting Venus for gravity assists to lose even more."

SpaceX's Falcon Heavy rocket can carry heavier cargo than the Delta 4-Heavy, but the launcher must complete multiple successful flights before NASA will allow it to dispatch the agency's most expensive science probes. At the time of NASA's selection of the Delta 4-Heavy rocket for the Parker Solar Probe mission in early 2015, the Falcon Heavy was still three years from its first test flight.

Parker Solar Probe will reach its first perihelion -- or close-up solar flyby -- on Nov. 1 at a distance of around 15 million miles (24.1 million kilometers).

Six more flybys with Venus will crank the probe closer to the sun over the course of 24 orbits through 2025.

Parker Solar Probe will eventually fly through the corona, a super-heated envelope of plasma surrounding the sun wh ere temperatures soar to millions of degrees. The temperature surface of the sun hundreds of times cooler, but still a blistering 10,000 degrees Fahrenheit (6,000 degrees Celsius).

"That just doesn't make sense," said Nicola Fox, Parker Solar Probe's project scientist at the Johns Hopkins University Applied Physics Laboratory, which built the spacecraft and leads the science team. "You have a heat source, and it gets hotter as you move away. It's like walking away from a campfire and suddenly getting hotter. iI breaks the laws of nature. It breaks the laws of physics."

Scientists believe the million-mile-per-hour solar wind, a stream of plasma that travels outward through the solar system, is generated inside the corona.

Fox said that inside the corona, plasma "gets incredibly energized, so much so that it actually takes off and can break away from the huge pull of the sun with so much energy that it can move out, and it bathes all of the planets. It carries with it the sun's magnetic field."

The result, Fox said, is that the Earth is impacted by solar activity, producing geomagnetic storms as the solar wind interacts with the planet's magnetosphere, activating colorful auroral displays, potentially damaging satellites and disrupting communications and electrical grids.

"We live in the atmosphere of the sun, so when the sun sneezes, the Earth will catch a cold," Fox said in a presentation last month at the SXSW festival in Austin, Texas. "We feel whatever is going on on the sun."

Key questions Parker Solar Probe was designed to address include charting the flow of heat and energy that accelerates the solar wind, collecting data that could help scientists forecast solar storms that might affect Earth.

During its closest approaches in 2024 and 2025, Parker Solar Probe will experience 478 times the sunlight present at Earth, which orbits around 93 million miles (150 kilometers) from the sun. The spacecraft's velocity will jump to roughly 430,000 mph -- 120 miles per second or nearly 700,000 kilometers per hour -- during its final perihelion passages.

Parker Solar Probe carries a heat shield to protect the spacecraft's most critical parts from the scorching temperatures, but the craft's power-generating solar panels and some parts of its scientific payload will remain exposed.

"We will be orbiting through the 3-million-degree plasma region," Fox said. "That sounds really hot, but the plasma there is not very dense. If you imagine turning your oven on to 400 degrees and letting it heat up, you could put your hand inside that oven. It won't burn you unless you touch something, so there's a difference between temperature and heat.

"There aren't that many particles around, so the actual amount that couples into the front side of our heat shield means that the front side is about 2,500 degrees Fahrenheit, or 1,400 degrees Centigrade (Celsius)," Fox said.

Behind the heat shield, or thermal protection system, the main body of the spacecraft will be warmed a little hotter than room temperature, but still within engineering tolerances for crucial parts like the probe's computer and propulsion system.

Parker Solar Probe's heat shield arrived at the Astrotech facility in Titusville, Florida, on April 18 in a ground shipment from the Johns Hopkins Applied Physics Laboratory, or APL, in Laurel, Maryland.

One of the major activities at Astrotech in the lead-up to launch will be the installation of the heat shield, a 4.5-inch thick (11.4-centimeter) piece of carbon composite that stretches around 8 feet (nearly 2.5 meters) wide.

"The idea of exploring this region around the sun has been around for about 60 years," Kinnison said. "The primary thing that's kept us from doing that is the heat shield technology that will allow you to survive there ... That was one of the more critical technologies that we had to develop."

Once the heat shield is bolted on to the spacecraft, engineers will transfer Parker Solar Probe to a hazardous fueling facility wh ere it will be loaded with hydrazine propellant. Then ground crews will connect the probe to its Star 48 upper stage motor and encapsulate it inside the Delta 4's payload fairing before moving the spacecraft to the launch pad.

Officials are still working to resolve a couple of technical issues before clearing Parker Solar Probe for launch.

Peg Luce, the acting director of NASA's heliophysics division at NASA Headquarters, said earlier this month that engineers are studying the failure of several platinum resistance thermometers on the spacecraft.

"The platinum resistance thermometers are lightweight, highly sensitive temperature sensors used to help provide feedback to the spacecraft's cooling system and solar arrays," said Dwayne Brown, a NASA spokesperson. "We put all spacecraft through a rigorous test program to make sure all systems are working as designed and it is normal for a test program to uncover issues."

Luce said the thermometers, which contain fine wiring, could be repaired or replaced during pre-launch processing in Florida, if necessary. After assessing the situation during recent review of Parker Solar Probe's status, officials unanimously approved the spacecraft's shipment from Maryland to Florida, Brown said.

"There are a number of tests that we're doing back at the lab to understand what's going on," Kinnison said. "These sorts of things happen with spacecraft wh ere you come up with an issue at the end of the day, and the team pulls together and figures out what needs to be done, and we get it done. That's what I'm expecting to happen here."

In a presentation to a heliophysics advisory committee April 5, Luce said the mission managers are also examining "some late breaking problems that are being worked and watched very carefully" regarding the Star 48 upper stage motor.

"It all looks like that will be smoothed out in time for launch," Luce said.

But she said NASA will not go forward with the launch if there are any lingering concerns.

"We are not going to fly this mission if we have concerns about it, and if we have to take more time, we will," Luce said.

Parker Solar Probe's launch period extends through Aug. 19, and is limited by the position of Venus in its orbit around the sun. If the mission misses its launch opportunity this year, the next chance to send Parker Solar Probe into space will come in May 2019.

NASA's Parker Solar Probe is rotated down to a horizontal position during pre-launch processing and testing on April 10, 2018, at Astrotech Space Operations in Titusville, Florida, just outside Kennedy Space Center. Once horizontal, the integration and testing team will measure the alignment of the heat shield mounting points with respect to the spacecraft structure. This is done to assure that the umbra (or shadow) cast by the heat shield - called the Thermal Protection System - protects the spacecraft and instruments.

With old IMAX projector bulbs, Michigan Engineers simulate the sun.

You don't get to swim in the sun's atmosphere unless you can prove you belong there. And the Parker Solar Probe's Faraday cup, a key sensor aboard the $1.5 billion NASA mission launching this summer, earned its stripes last week by enduring testing in a homemade contraption designed to simulate the sun.

The cup will scoop up and examine the solar wind as the probe passes closer to the sun than any previous manmade object. Justin Kasper, University of Michigan associate professor of climate and space sciences and engineering, is principal investigator for Parker's Solar Wind Electrons Alphas and Protons (SWEAP) investigation.

In order to confirm the cup will survive the extreme heat and light of the sun's corona, researchers previously tortured a model of the Faraday cup at temperatures exceeding 3,000 degrees Fahrenheit, courtesy of the Oak Ridge National Laboratory's Plasma Arc Lamp. The cup, built from refractory metals and sapphire crystal insulators, exceeded expectations.

But the final test took place last week, in a homemade contraption Kasper and his research team call the Solar Environment Simulator. While being blasted with roughly 10 kilowatts of light on its surface--enough to heat a sheet of metal to 1,800 degrees Fahrenheit in seconds--the Faraday cup model ran through its paces, successfully scanning a simulated stream of solar wind.

"Watching the instrument track the signal from the ion beam as if it was plasma flowing from the Sun was a thrilling preview of what we will see with Parker Solar Probe," Kasper said.

Roilings in the sun's atmosphere can violently fling clouds of plasma into space, known as coronal mass ejections, sometimes directly at Earth. Without precautionary measures, such clouds can set up geomagnetic oscillations around Earth that can trip up satellite electronics, interfere with GPS and radio communications and--at their worst--can create surges of current through power grids that can overload and disrupt the system for extended periods of time, up to months.

By understanding what makes up the solar corona and what drives the constant outpouring of solar material from the sun, scientists on Earth will be better equipped to interpret the solar activity we see from afar and create a better early-warning system. That's wh ere Parker Solar Probe, slated for launch on July 31, 2018, comes in, with its complement of experiments that includes the Faraday cup.

To test the cup model, researchers had to create something new. Their simulator sits in a first-floor lab at the Smithsonian Astrophysical Observatory in Cambridge, Mass. and embodies the adage that necessity is the mother of invention.

It has the look of a makeshift operating room, with a metal frame holding up thick blue tarps around three sides creating a 16 x 8 workspace.

Inside the area, recreating the sun's heat and light fell to a quartet of modified older model IMAX projectors that Kasper's team purchased on eBay for a few thousand dollars apiece. These are not the digital machines you find in today's Cineplexes, but an earlier generation that utilized bulbs.

"It turns out a movie theater bulb on an IMAX projector runs at about the same 5,700 degrees Kelvin--the same effective temperature as the surface of the sun," Kasper said. "And it gives off nearly the same spectrum of light as the surface."

Space offers essentially no atmosphere, meaning a proper testing environment for the Faraday cup would have as little air as possible. So researchers placed the cup in a metal vacuum chamber for testing.

Resembling an iron lung, the seven-foot-long silver chamber has a hatch at one end that swings outward and has a small round window in it. The night before testing, the team began pumping the atmosphere out of the vacuum chamber.

By the time the simulation cranked up for testing, the chamber registered roughly one-billionth of the Earth's atmosphere.

All four of the IMAX projectors sit atop wheeled tables, and to set up for the test, researchers rolled them into place, with their beams pointed through the vacuum tube window directly at the Faraday cup.

(https://cm-web-news-files.s3.amazonaws.com/uploads/2018/04/Solar-Probe-GIF.gif)
The Solar Probe Cup is exposed to radiation and light as powerful as the sun as researchers look to pass the final test before the launch of the Parker Solar Probe

The final element of the simulator is its ability to generate the kinds of particles the Faraday cup will need to sense and evaluate. To do that, the team attached an ion gun to the vacuum tube hatch, with the "barrel" of the device reaching inside and pointed at the cup.

"The ion gun takes a pellet of metal and heats it up," said Anthony Case, an astrophysicist at the Harvard Smithsonian Institute for Astrophysics. "When it gets hot, ions start boiling off this piece of metal. Then you hook it up to a battery, accelerating the ions out of the gun. And we can direct them right toward the Faraday cup's aperture wh ere they'll be measured."

In this final test, the Faraday cup took the heat and delivered--putting Parker Solar Probe on track for its summer launch.

Kelly Korreck, a U-M alumna and astrophysicist at the Institute, serves as head of science operations on Parker's SWEAP investigation as well as SWEAP activities for the Smithsonian.

"As for the test today, it confirmed what I had suspected--when you take an amazing team of scientists and engineers, give them a complex, difficult, interesting project and the motivation of exploring a region of the universe humankind has never been to before, remarkable things happen," she said.

NASA's Parker Solar Probe gets its power from the Sun, so the solar arrays that collect energy from our star need to be in perfect working order. This month, members of the mission team tested the arrays at Astrotech Space Operations in Titusville, Florida, to ensure the system performs as designed and provides power to the spacecraft during its historic mission to the Sun.

More Than 1.1 Million Names Installed on NASA's Parker Solar Probe

Throughout its seven-year mission, NASA's Parker Solar Probe will swoop through the Sun's atmosphere 24 times, getting closer to our star than any spacecraft has gone before. The spacecraft will carry more than scientific instruments on this historic journey -- it will also hold more than 1.1 million names submitted by the public to go to the Sun.
"Parker Solar Probe is going to revolutionize our understanding of the Sun, the only star we can study up close," said Nicola Fox, project scientist for Parker Solar Probe at the Johns Hopkins Applied Physics Lab in Laurel, Maryland. "It's fitting that as the mission undertakes one of the most extreme journeys of exploration ever tackled by a human-made object, the spacecraft will also carry along the names of so many people who are cheering it on its way."
Цитата"Let's see what lies ahead."
- Gene Parker, July 2017
Back in March 2018, the public were invited to send their names to the Sun aboard humanity's first mission to "touch" a star. A total of 1,137,202 names were submitted and confirmed over the seven-and-a-half-week period, and a memory card containing the names was installed on the spacecraft on May 18, 2018, three months before the scheduled launch on July 31, 2018, from NASA's Kennedy Space Center in Florida. The card was mounted on a plaque bearing a dedication to and a quote from the mission's namesake, heliophysicist Eugene Parker, who first theorized the existence of the solar wind. This is the first NASA mission to be named for a living individual.

This memory card also carries photos of Parker, professor emeritus at the University of Chicago, and a copy of his groundbreaking 1958 scientific paper. Parker proposed a number of concepts about how stars -- including our Sun -- give off material. He called this cascade of energy and particles the solar wind, a constant outflow of material from the Sun that we now know shapes everything from the habitability of worlds to our solar system's interaction with the rest of the galaxy.

Parker Solar Probe will explore the Sun's outer atmosphere and make critical observations to answer decades-old questions about the physics of stars. The resulting data may also improve forecasts of major eruptions on the Sun and subsequent space weather events that impact life on Earth, as well as satellites and astronauts in space.

Though our understanding of the Sun and the solar wind has vastly improved since Parker first theorized the solar wind, there are still questions left unanswered. Two of the most fundamental mysteries - which scientists hope Parker Solar Probe will help solve - are the coronal heating problem and the mechanism behind solar wind acceleration.

(https://www.nasa.gov/sites/default/files/styles/full_width/public/thumbnails/image/plaquechip3.jpg?itok=UWXrz0E8) (https://www.nasa.gov/sites/default/files/thumbnails/image/plaquechip3.jpg)
In addition to a chip containing submitted names, the plaque installed on the Parker Solar Probe spacecraft also contains a dedication to and quote from Eugene Parker, the mission's namesake. It reads: "The Parker Solar Probe mission is dedicated to Dr. Eugene N. Parker whose profound contributions have revolutionized our understanding of the Sun and solar wind. 'Let's see what lies ahead' Gene Parker, July 2017"

The coronal heating problem is what scientists call the apparent mismatch between the temperature of the Sun's photosphere -- the visible "surface," measuring about 10,000 degrees Fahrenheit -- and the much higher temperature of the corona -- the Sun's atmosphere, which reaches temperatures of up to 10 million degrees Fahrenheit. Since the Sun's energy source is at its core, this increase is similar to walking away from a campfire and suddenly feeling a thousand times hotter -- completely counterintuitive. This implies that some other process is continually adding more heat to that solar atmosphere.

Scientists think that the mechanism behind this as-yet unexplained heating happens in the lower corona -- and Parker Solar Probe will get closer to this region than any spacecraft has before. Getting a closer look at this region should help scientists identify the source of this coronal heating, along with pinpointing the process that accelerates the solar wind to enormous speeds as it leaves the Sun.

A commemorative reproduction of the plaque bearing an identical memory card -- minus the submitted names -- was presented to Parker at the Johns Hopkins University Applied Physics Lab in October 2017 by the mission team.

"From the experience of seeing the probe up close, I understand now the difficult task you are undertaking, and I am sure you will succeed," said Parker after visiting the spacecraft in the clean room (https://www.nasa.gov/feature/goddard/2017/parker-solar-probe-gets-visit-from-namesake).

The plaque containing names submitted to travel to the Sun is mounted below Parker Solar Probe's high-gain antenna (the round object with gray covering), which the spacecraft will use to transmit data back to Earth.

NASA's Parker Solar Probe depends on the Sun, not just as an object of scientific investigation, but also for the power that drives its instruments and systems. On Thursday, May 31, 2018, the spacecraft's solar arrays were installed and tested. These arrays will power all of the spacecraft's systems, including the suites of scientific instruments studying the solar wind and the Sun's corona as well as the Solar Array Cooling System (SACS) that will protect the arrays from the extreme heat at the Sun.

"Unlike solar-powered missions that operate far from the Sun and are focused only on generating power from it, we need to manage the power generated along with the substantial heat that comes from being so close to the Sun," said Andy Driesman, project manager from the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. "When we're out around the orbit of Venus, we fully extend the arrays to get the power we need. But when we're near the Sun, we tuck the arrays back until only a small wing is exposed, and that portion is enough to provide needed electrical power."

The solar arrays are cooled by a gallon of water that circulates through tubes in the arrays and into large radiators at the top of the spacecraft. They are just over three and a half feet (1.12 meters) long and nearly two and a half feet (0.69 meters) wide. Mounted on motorized arms, the arrays will retract almost all of their surface behind the Thermal Protection System - the heat shield - when the spacecraft is close to the Sun. The solar array installation marks some of the final preparation and testing of Parker Solar Probe leading up to the mission's July 31 launch date.

• Rocket: Delta IV Heavy
• Mission: Parker Solar Probe
• Launch Date: No earlier than Tuesday, July 31, 2018
• Launch Broadcast: Details to come
• Launch Location: Space Launch Complex-37, Cape Canaveral Air Force Station, Florida

Mission Information: Parker Solar Probe is humanity's first mission to the sun. After launch, it will orbit directly through the solar atmosphere - the corona - closer to the surface than any human-made object has ever gone. While facing brutal heat and radiation, the mission will reveal fundamental science behind what drives the solar wind, the constant outpouring of material from the sun that shapes planetary atmospheres and affects space weather near Earth.

Parker Solar Probe is part of NASA's Living With a Star Program to explore aspects of the connected sun-Earth system that directly affect life and society.

Launch Notes: Parker Solar Probe is expected to break the record for the fastest spacecraft to leave Earth's atmosphere, a record set by the New Horizons mission during launch on an Atlas V in 2006. Due to the extremely high energy required for this mission, the Delta IV Heavy's capability will be augmented by a powerful third stage provided by Orbital ATK.

NASA and the Johns Hopkins University Applied Physics Laboratory are now targeting launch of the agency's Parker Solar Probe spacecraft no earlier than Aug. 4, 2018. Originally scheduled to launch on July 31, additional time is needed to accommodate further software testing of spacecraft systems. The Parker Solar Probe will launch on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida.

Parker Solar Probe will fly closer to the Sun's surface than any spacecraft before it, facing brutal heat and radiation conditions and ultimately providing humanity with the first-ever samplings of a star's corona.

ЦитатаСША сдвинули срок запуска своего зонда для исследования Солнца

Космос (http://tass.ru/kosmos) | 3 июля, 10:28 UTC+3

ВАШИНГТОН, 3 июля. /Корр. ТАСС Дмитрий Кирсанов/. Национальное управление США по аэронавтике и исследованию космического пространства (NASA) сдвинуло срок запуска американской автоматической межпланетной станции, предназначенной для исследования Солнца. Теперь, по свидетельству NASA, стартовое окно открывается "не ранее 4 августа", а не 31 июля. Закрывается оно 19 августа.

"Дополнительное время требуется для дальнейшего тестирования программного обеспечения систем аппарата", - отметило NASA. Вдаваться в детали и пояснять, что именно проходит дополнительные испытания, почему они потребовались, в космическом ведомстве США категорически отказались. "Вся наша обновленная информация будет появляться на сайте миссии в интернете. Стартовое окно по- прежнему открывается 4 августа", - сказала в понедельник корреспонденту ТАСС сотрудник пресс-службы NASA.

Весной станция была переброшена к космодрому на мысе Канаверал (штат Флорида), с которого ей предстоит стартовать. В понедельник была открыта аккредитация журналистов, желающих принять участие в освещении данной, как выражается NASA, "исторической миссии".

Последние приготовления
В ночь со 2 на 3 апреля зонд был перевезен из входящего в структуру NASA Центра космических полетов имени Годдарда в Гринбелте (штат Мэриленд) на расположенную поблизости базу ВВС и ВМС США Эндрюс. Оттуда аппарат на борту военно-транспортного самолета C-17 доставили на сборочное предприятие компании Astrotech Space Operations, соседствующее с космодромом на мысе Канаверал. Затем зонд со всей предосторожностью извлекли из контейнера, в котором он перебрасывался из Мэриленда во Флориду.

На объекте фирмы Astrotech Space Operations у космодрома на мысе Канаверал станция проходит последние всеобъемлющие испытания.

Кроме того, там ее "упакуют" в специальное термозащитное покрытие, заправят топливом, укроют носовым обтекателем и установят на тяжелую ракету-носитель Delta IV.
В условиях, "приближенных к боевым"
С января на протяжении почти двух месяцев станцию подвергали температурным испытаниях в вакууме. Эти тесты шли в Центре имени Годдарда, где зонд, который по размерам сопоставим с небольшим автомобилем, поместили в вакуумную камеру высотой примерно 12 м.

Инженеры сначала проверяли, выдерживают ли зонд и его "начинка" низкую температуру - до минус 292 градусов Фаренгейта (минус 180 Цельсия). Затем ее постепенно увеличивали, чтобы посмотреть, как на станцию воздействует экстремально высокая температура. Потом специалисты чередовали такой перепад температур, имитируя условия полета в космическом пространстве.
Детали миссии
Планируется, что в ноябре зонд приблизится к Солнцу на расстояние в 6,4 млн км. Это означает, что аппарат будет находиться в пределах короны Солнца, то есть внешних слоев его атмосферы, где температура может достигать 500 тыс. кельвинов (около 500 тыс. градусов по Цельсию) и даже нескольких миллионов кельвинов.

По замыслу американских ученых, в период по июнь 2025 года зонд совершит 24 витка по орбите вокруг Солнца, разгоняясь до скорости 724 тыс. км в час. На каждый такой виток у него будет уходить 88 дней.

На борту аппарата стоимостью порядка $1,5 млрд будет находиться четыре комплекта научных инструментов. При помощи этой аппаратуры специалисты рассчитывают, в частности, осуществить различные измерения солнечной радиации. Наряду с этим зонд должен будет передать фотоснимки, которые станут первыми, сделанными в пределах солнечной короны. Оборудование устройства будет защищено оболочкой из углепластика толщиной 11,43 см, позволяющей выдержать температуру до примерно 1,4 тыс. градусов по Цельсию.

Как признала в июне прошлого года координатор проекта Никола Фокс, его удалось реализовать только теперь благодаря появлению новых материалов, использованных в первую очередь при создании термостойкого щита зонда. Станция получит и новые панели солнечных батарей, уточнила Фокс. "Мы наконец прикоснемся к Солнцу", - эмоционально сказала о курируемом проекте специалист. По ее выражению, зонд поможет ученым понять, "как работает Солнце".
Значение проекта
NASA обещает, что миссия произведет революцию в представлении человека о процессах, протекающих на Солнце. Претворение в жизнь намеченных планов позволит внести "фундаментальный вклад" в понимание причин "нагревания солнечной короны", а также возникновения солнечного ветра (потока ионизированных частиц, истекающего из солнечной короны) и "ответить на критически важные вопросы в гелиофизике, которые уже на протяжении нескольких десятилетий имеют высший приоритет", убеждено NASA. Информация с борта аппарата, по мнению его специалистов, будет иметь огромную ценность и с точки зрения подготовки дальнейших пилотируемых полетов за пределы Земли, поскольку позволит прогнозировать "радиационную обстановку, в которой предстоит работать и жить будущим покорителям космоса".

Зонд назван в честь выдающегося американского астрофизика Юджина Паркера, которому минувшим летом исполнилось 90 лет. Несмотря на почтенный возраст, он до сих пор ведет научную деятельность в Университете Чикаго (штат Иллинойс).

Паркер стал одним из первых в мире специалистов, занимавшихся исследованиями солнечного ветра. С 1967 года он является членом Национальной академии наук США.

Предполагается, что зонд Паркера подлетит в семь раз ближе к Солнцу, чем какой-либо другой из космических аппаратов, ранее отправлявшихся человеком.

Cutting-Edge Heat Shield Installed on NASA's Parker Solar Probe

The launch of Parker Solar Probe, the mission that will get closer to the Sun than any human-made object has ever gone, is quickly approaching, and on June 27, 2018, Parker Solar Probe's heat shield -- called the Thermal Protection System, or TPS -- was installed on the spacecraft.

A mission 60 years in the making, Parker Solar Probe will make a historic journey to the Sun's corona, a region of the solar atmosphere. With the help of its revolutionary heat shield, now permanently attached to the spacecraft in preparation for its August 2018 launch, the spacecraft's orbit will carry it to within 4 million miles of the Sun's fiercely hot surface, where it will collect unprecedented data about the inner workings of the corona.

The eight-foot-diameter heat shield will safeguard everything within its umbra, the shadow it casts on the spacecraft. At Parker Solar Probe's closest approach to the Sun, temperatures on the heat shield will reach nearly 2,500 degrees Fahrenheit, but the spacecraft and its instruments will be kept at a relatively comfortable temperature of about 85 degrees Fahrenheit.

The heat shield is made of two panels of superheated carbon-carbon composite sandwiching a lightweight 4.5-inch-thick carbon foam core. The Sun-facing side of the heat shield is also sprayed with a specially formulated white coating to reflect as much of the Sun's energy away from the spacecraft as possible.

The heat shield itself weighs only about 160 pounds -- here on Earth, the foam core is 97 percent air. Because Parker Solar Probe travels so fast -- 430,000 miles per hour at its closest approach to the Sun, fast enough to travel from Philadelphia to Washington, D.C., in about one second -- the shield and spacecraft have to be light to achieve the needed orbit.

The reinstallation of the Thermal Protection System -- which was briefly attached to the spacecraft during testing at the Johns Hopkins Applied Physics Lab in Laurel, Maryland, in fall 2017 -- marks the first time in months that Parker Solar Probe has been fully integrated. The heat shield and spacecraft underwent testing and evaluation separately at NASA's Goddard Space Flight Center in Greenbelt, Maryland, before shipping out to Astrotech Space Operations in Titusville, Florida, in April 2018. With the recent reunification, Parker Solar Probe inches closer to launch and toward the Sun.

Parker Solar Probe is part of NASA's Living with a Star Program, or LWS, to explore aspects of the Sun-Earth system that directly affect life and society. LWS is managed by Goddard for the Heliophysics Division of NASA's Science Mission Directorate in Washington, D.C. The Johns Hopkins Applied Physics Laboratory manages the Parker Solar Probe mission for NASA. APL designed and built the spacecraft and will also operate it.

Teams require additional time for processing NASA's Parker Solar Probe spacecraft after discovering a minor tubing leak in the ground support equipment during final processing. The tubing is being repaired, and the spacecraft is healthy. As always, operations take precedence during launch and we needed to cancel media day activities on July 13, 2018. NASA will make every effort to provide updated imagery of the spacecraft prior to encapsulation.

Parker Solar Probe is the agency's mission to touch the Sun. It is scheduled to launch on a United Launch Alliance Delta IV Heavy no earlier than Aug. 4, 2018, from Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida.

Traveling to the Sun: Why Won't Parker Solar Probe Melt?

This summer, NASA's Parker Solar Probe will launch to travel closer to the Sun, deeper into the solar atmosphere, than any mission before it. If Earth was at one end of a yard-stick and the Sun on the other, Parker Solar Probe will make it to within four inches of the solar surface.

Inside that part of the solar atmosphere, a region known as the corona, Parker Solar Probe will provide unprecedented observations of what drives the wide range of particles, energy and heat that course through the region -- flinging particles outward into the solar system and far past Neptune.

Inside the corona, it's also, of course, unimaginably hot. The spacecraft will travel through material with temperatures greater than a million degrees Fahrenheit while being bombarded with intense sun light.

So, why won't it melt?

Parker Solar Probe has been designed to withstand the extreme conditions and temperature fluctuations for the mission. The key lies in its custom heat shield and an autonomous system that helps protect the mission fr om the Sun's intense light emission, but does allow the coronal material to "touch" the spacecraft.

The Science Behind Why It Won't Melt

One key to understanding what keeps the spacecraft and its instruments safe, is understanding the concept of heat versus temperature. Counterintuitively, high temperatures do not always translate to actually heating another object.

In space, the temperature can be thousands of degrees without providing significant heat to a given object or feeling hot. Why? Temperature measures how fast particles are moving, whereas heat measures the total amount of energy that they transfer. Particles may be moving fast (high temperature), but if there are very few of them, they won't transfer much energy (low heat). Since space is mostly empty, there are very few particles that can transfer energy to the spacecraft.

The corona through which Parker Solar Probe flies, for example, has an extremely high temperature but very low density. Think of the difference between putting your hand in a hot oven versus putting it in a pot of boiling water (don't try this at home!) -- in the oven, your hand can withstand significantly hotter temperatures for longer than in the water wh ere it has to interact with many more particles. Similarly, compared to the visible surface of the Sun, the corona is less dense, so the spacecraft interacts with fewer hot particles and doesn't receive as much heat.

That means that while Parker Solar Probe will be traveling through a space with temperatures of several million degrees, the surface of the heat shield that faces the Sun will only get heated to about 2,500 degrees Fahrenheit (about 1,400 degrees Celsius).

The Shield That Protects It

Of course, thousands of degrees Fahrenheit is still fantastically hot. (For comparison, lava from volcano eruptions can be anywhere between 1,300 and 2,200 F (700 and 1,200 C) And to withstand that heat, Parker Solar Probe makes use of a heat shield known as the Thermal Protection System, or TPS, which is 8 feet (2.4 meters) in diameter and 4.5 inches (about 115 mm) thick. Those few inches of protection mean that just on the other side of the shield, the spacecraft body will sit at a comfortable 85 F (30 C).

The TPS was designed by the Johns Hopkins Applied Physics Laboratory, and was built at Carbon-Carbon Advanced Technologies, using a carbon composite foam sandwiched between two carbon plates. This lightweight insulation will be accompanied by a finishing touch of white ceramic paint on the sun-facing plate, to reflect as much heat as possible. Tested to withstand up to 3,000 F (1,650 C), the TPS can handle any heat the Sun can send its way, keeping almost all instrumentation safe.

The Cup that Measures the Wind

But not all of the Solar Parker Probe instruments will be behind the TPS.

Poking out over the heat shield, the Solar Probe Cup is one of two instruments on Parker Solar Probe that will not be protected by the heat shield. This instrument is what's known as a Faraday cup, a sensor designed to measure the ion and electron fluxes and flow angles from the solar wind. Due to the intensity of the solar atmosphere, unique technologies had to be engineered to make sure that not only can the instrument survive, but also the electronics aboard can send back accurate readings.

Parker Solar Probe's heat shield is made of two panels of superheated carbon-carbon composite sandwiching a lightweight 4.5-inch-thick carbon foam core. To reflect as much of the Sun's energy away from the spacecraft as possible, the Sun-facing side of the heat shield is also sprayed with a specially formulated white coating.

The cup itself is made from sheets of Titanium-Zirconium-Molybdenum, an alloy of molybdenum, with a melting point of about 4,260 F (2,349 C). The chips that produce an electric field for the Solar Probe Cup are made from tungsten, a metal with the highest known melting point of 6,192 F (3,422 C). Normally lasers are used to etch the gridlines in these chips -- however due to the high melting point acid had to be used instead.

Another challenge came in the form of the electronic wiring -- most cables would melt from exposure to heat radiation at such close proximity to the Sun. To solve this problem, the team grew sapphire crystal tubes to suspend the wiring, and made the wires from niobium.

To make sure the instrument was ready for the harsh environment, the researchers needed to mimic the Sun's intense heat radiation in a lab. To create a test-worthy level of heat, the researchers used a particle accelerator and IMAX projectors -- jury-rigged to increase their temperature. The projectors mimicked the heat of the Sun, while the particle accelerator exposed the cup to radiation to make sure the cup could measure the accelerated particles under the intense conditions. To be absolutely sure the Solar Probe Cup would withstand the harsh environment, the Odeillo Solar Furnace -- which concentrates the heat of the Sun through 10,000 adjustable mirrors -- was used to test the cup against the intense solar emission.

The Solar Probe Cup passed its tests with flying colors -- indeed, it continued to perform better and give clearer results the longer it was exposed to the test environments. "We think the radiation removed any potential contamination," Justin Kasper, principal investigator for the SWEAP instruments at the University of Michigan in Ann Arbor, said. "It basically cleaned itself."

The Spacecraft That Keeps its Cool

Several other designs on the spacecraft keep Parker Solar Probe sheltered from the heat. Without protection, the solar panels -- which use energy from the very star being studied to power the spacecraft -- can overheat. At each approach to the Sun, the solar arrays retract behind the heat shield's shadow, leaving only a small segment exposed to the Sun's intense rays.

But that close to the Sun, even more protection is needed. The solar arrays have a surprisingly simple cooling system: a heated tank that keeps the coolant from freezing during launch, two radiators that will keep the coolant from freezing, aluminum fins to maximize the cooling surface, and pumps to circulate the coolant. The cooling system is powerful enough to cool an average sized living room, and will keep the solar arrays and instrumentation cool and functioning while in the heat of the Sun.

In the Astrotech processing facility in Titusville, Florida, near NASA's Kennedy Space Center, on Tuesday, June 5, 2018, technicians and engineers perform light bar testing on NASA's Parker Solar Probe. The spacecraft will launch on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida. The mission will perform the closest-ever observations of a star when it travels through the Sun's atmosphere, called the corona. The probe will rely on measurements and imaging to revolutionize our understanding of the corona and the Sun-Earth connection.

The coolant used for the system? About a gallon (3.7 liters) of deionized water. While plenty of chemical coolants exist, the range of temperatures the spacecraft will be exposed to varies between 50 F (10 C) and 257 F (125 C). Very few liquids can handle those ranges like water. To keep the water from boiling at the higher end of the temperatures, it will be pressurized so the boiling point is over 257 F (125 C).

Another issue with protecting any spacecraft is figuring out how to communicate with it. Parker Solar Probe will largely be alone on its journey. It takes light eight minutes to reach Earth -- meaning if engineers had to control the spacecraft from Earth, by the time something went wrong it would be too late to correct it.

So, the spacecraft is designed to autonomously keep itself safe and on track to the Sun. Several sensors, about half the size of a cell phone, are attached to the body of the spacecraft along the edge of the shadow from the heat shield. If any of these sensors detect sunlight, they alert the central computer and the spacecraft can correct its position to keep the sensors, and the rest of the instruments, safely protected. This all has to happen without any human intervention, so the central computer software has been programmed and extensively tested to make sure all corrections can be made on the fly.

Launching Toward the Sun

After launch, Parker Solar Probe will detect the position of the Sun, align the thermal protection shield to face it and continue its journey for the next three months, embracing the heat of the Sun and protecting itself from the cold vacuum of space.

Over the course of seven years of planned mission duration, the spacecraft will make 24 orbits of our star. On each close approach to the Sun it will sample the solar wind, study the Sun's corona, and provide unprecedentedly close up observations from around our star -- and armed with its slew of innovative technologies, we know it will keep its cool the whole time.

The launch of NASA's Parker Solar Probe, on the verge of kicking off a seven-year mission culminating in passages through the sun's atmosphere, has been delayed to Aug. 6 to resolve a technical snag encountered during encapsulation of the spacecraft inside the nose shroud of its United Launch Alliance Delta 4-Heavy rocket.

The two-day delay fr om the previous target launch date of Aug. 4 was announced by NASA late Wednesday, as ground crews inside the Astrotech spacecraft processing facility in Titusville, Florida, encapsulated Parker Solar Probe inside the payload fairing of its Delta 4-Heavy launch vehicle.

"Additional time was needed to evaluate the configuration of a cable clamp on the payload fairing," NASA said. "Teams have modified the configuration and encapsulation operations have continued."

Liftoff is planned for approximately 4:08 a.m. EDT (0808 GMT) Aug. 6.
The spacecraft and its Star 48 upper stage motor, which will provide an extra push to the probe after its launch fr om Cape Canaveral, are scheduled to head for the Complex 37 launch pad in the coming days for lifting atop the Delta 4-Heavy, the post powerful rocket in ULA's fleet.

NASA said technicians at the Astrotech processing facility have repaired a leak discovered last week in purge ground support tubing on the Star 48 rocket motor.

The launch was originally scheduled for July 31, the opening of a 19-day interplanetary launch period governed by the positions of Earth and Venus. Parker Solar Probe will depart Earth on a trajectory to fly by Venus in September, the first of seven gravity assist maneuvers with Earth's sister planet to crank the spacecraft's orbit closer to the sun.

Parker Solar Probe will gradually approach the sun, moving closer after each flyby of Venus before reaching a perihelion -- or closest point to the sun -- at a distance of around 3.8 million miles (about 6.2 million kilometers) in late 2024. That's well inside the orbit of Mercury, and closer to the sun than the U.S.-German Helios 2 mission reached during its record-setting mission in 1976.

The mission is named for Eugene Parker, the scientist who predicted in 1958 the influence of the solar wind, a stream of plasma that travels outward through the solar system.

Fitted with a custom carbon composite heat shield, Parker Solar Probe will fly through the corona, a super-heated envelope of plasma surrounding the sun wh ere temperatures soar to millions of degrees. The temperature at the surface of the sun is hundreds of times cooler, but still a blistering 10,000 degrees Fahrenheit (6,000 degrees Celsius).

"That just doesn't make sense," said Nicola Fox, Parker Solar Probe's project scientist at the Johns Hopkins University Applied Physics Laboratory, which built the spacecraft and leads the science team. "You have a heat source, and it gets hotter as you move away. It's like walking away from a campfire and suddenly getting hotter. It breaks the laws of nature. It breaks the laws of physics."

Scientists believe the million-mile-per-hour solar wind is generated inside the corona.

Key questions Parker Solar Probe was designed to address include charting the flow of heat and energy that accelerates the solar wind, collecting data that could help scientists forecast solar storms that might affect Earth.

Since arriving in Florida from the Johns Hopkins University Applied Physics Laboratory in April, Parker Solar Probe has been tested and had its heat shield installed. Ground crews have filled the craft with hydrazine fuel, and mounted it on its Star 48 rocket motor, built by Northrop Grumman Innovation Systems, formerly known as Orbital ATK.

Even ULA's Delta 4-Heavy rocket, one of the most powerful launchers in the world, is unable to give Parker Solar Probe enough speed to get started on its lengthy, circuitous route through the inner solar system. Engineers devised the unique combination of the two-stage Delta 4-Heavy and the Star 48 upper stage motor to meet the requirements for Parker's high-speed departure from Earth.

Engineers crafted a similar arrangement for the launch of NASA's New Horizons spacecraft on an Atlas 5 rocket in 2006, adding an extra solid-fueled upper stage to give the probe enough velocity to make a speedy nine-year trip to Pluto.

Officials pushed back Parker's launch from July 31 to Aug. 4 in order to conduct additional software testing of spacecraft systems.

Tim Dunn, a launch director at NASA's Launch Services Program at the Kennedy Space Center, said last month that Parker Solar Probe engines wanted to complete further modeling and testing of temperature sensors on the spacecraft. The probe's platinum resistance thermometers provide data feedback to the craft's solar arrays and cooling system during its passage through the scorching solar corona.

"Right before they shipped (to Florida), they were having some temp sensor hardware issues on the spacecraft," Dunn said. "So what they wanted to do is they wanted to further evaluate wh ere they were with that system and do some more modeling, additional testing and then they needed to take that through the layers of the independent review."

ULA's launch team put the Delta 4-Heavy rocket through a pair of fueling tests, or wet dress rehearsals, earlier this month on its launch pad at Cape Canaveral.

Parker Solar Probe's interplanetary launch window closes Aug. 19, but ULA and NASA engineers have plotted launch trajectories for four additional days through Aug. 23, Dunn said.

"However, there is still discussion from the spacecraft (team) as to whether they want to choose to accept that," Dunn said. "The deeper we get into our window and we haven't launched, they may change their decision-making process."

If Parker misses its launch period in August, the next opportunity to send the mission toward the sun will open in May 2019.

We have created a "where's Parker?" web viewer. To help navigate where our Parker spacecraft will be in the future and to better understand how close to the Sun it will be going, check out our new interactive web tool (http://www.spaceforecaster.com/parker/index.html) that we quickly prototyped in a week.
A freshman intern fr om the US Naval Academy (Abhishek Gorti (http://abhishek.cc/)) worked closely with me over the summer, and we spent a week to prototype a web development tool that everyone can use. All the software to recreate the orbit viewer is open source and available (https://github.com/nasa902neel/nasa902neel.github.io).

As an inspiration fr om our earlier blog about interactive touch-tables (https://blogs.nasa.gov/stem-innovation-lab/2018/07/06/interactive-multi-touch-tables-too-daunting-to-create-software/?preview_id=80&preview_nonce=ab6c7f2ecd&post_format=standard&_thumbnail_id=104&preview=true), we used D3 software web development to create an interactive display on the internet for everyone to better understand wh ere the Parker spacecraft is going.

The telemetry data for Parker came directly from the raw orbital information, which was then saved into a simple asii format. The file is available in our open source repo linked above. So feel free to take it to better understand for yourself.

What other features do you think would be really cool to add? Anyone brave enough to take our repo and add something on top, maybe a circle wh ere the planets, Venus and Mercury, are located? Let us know how you get along!!

Parker Solar Probe will swoop to within 4 million miles of the sun's surface, facing heat and radiation like no spacecraft before it. Launching in 2018, Parker Solar Probe will provide new data on solar activity and make critical contributions to our ability to forecast major space-weather events that impact life on Earth.

In order to unlock the mysteries of the corona, but also to protect a society that is increasingly dependent on technology from the threats of space weather, NASA will send Parker Solar Probe to touch the Sun.

In 2017, the mission was renamed for Eugene Parker, the S. Chandrasekhar Distinguished Service Professor Emeritus, Department of Astronomy and Astrophysics at the University of Chicago. In the 1950s, Parker proposed a number of concepts about how stars--including our Sun- -give off energy. He called this cascade of energy the solar wind, and he described an entire complex system of plasmas, magnetic fields, and energetic particles that make up this phenomenon. Parker also theorized an explanation for the superheated solar atmosphere, the corona, which is - contrary to what was expected by physics laws -- hotter than the surface of the sun itself.

This is the first NASA mission that has been named for a living individual.

Early on an August morning, the sky near Cape Canaveral, Florida, will light up with the launch of Parker Solar Probe. No earlier than Aug. 6, 2018, a United Launch Alliance Delta IV Heavy will thunder to space carrying the car-sized spacecraft, which will study the Sun closer than any human-made object ever has.

On July 20, 2018, Nicky Fox, Parker Solar Probe's project scientist at the Johns Hopkins University Applied Physics Lab in Laurel, Maryland, and Alex Young, associate director for science in the Heliophysics Science Division at NASA's Goddard Space Flight Center in Greenbelt, Maryland, introduced Parker Solar Probe's science goals and the technology behind them at a televised press conference fr om NASA's Kennedy Space Center in Cape Canaveral, Florida.
"We've been studying the Sun for decades, and now we're finally going to go where the action is," said Young.

Our Sun is far more complex than meets the eye. Rather than the steady, unchanging disk it seems to human eyes, the Sun is a dynamic and magnetically active star. The Sun's atmosphere constantly sends magnetized material outward, enveloping our solar system far beyond the orbit of Pluto and influencing every world along the way. Coils of magnetic energy can burst out with light and particle radiation that travel through space and create temporary disruptions in our atmosphere, sometimes garbling radio and communications signals near Earth. The influence of solar activity on Earth and other worlds are collectively known as space weather, and the key to understanding its origins lies in understanding the Sun itself.

"The Sun's energy is always flowing past our world," said Fox. "And even though the solar wind is invisible, we can see it encircling the poles as the aurora, which are beautiful - but reveal the enormous amount of energy and particles that cascade into our atmosphere. We don't have a strong understanding of the mechanisms that drive that wind toward us, and that's what we're heading out to discover."

That's where Parker Solar Probe comes in. The spacecraft carries a lineup of instruments to study the Sun both remotely and in situ, or directly. Together, the data from these state-of-the-art instruments should help scientists answer three foundational questions about our star.

A Sun-skimming mission like Parker Solar Probe has been a dream of scientists for decades, but only recently has the needed technology - like the heat shield, solar array cooling system, and fault management system - been available to make such a mission a reality.

One of those questions is the mystery of the acceleration of the solar wind, the Sun's constant outflow of material. Though we largely grasp the solar wind's origins on the Sun, we know there is a point - as-yet unobserved - wh ere the solar wind is accelerated to supersonic speeds. Data shows these changes happen in the corona, a region of the Sun's atmosphere that Parker Solar Probe will fly directly through, and scientists plan to use Parker Solar Probe's remote and in situ measurements to shed light on how this happens.

Second, scientists hope to learn the secret of the corona's enormously high temperatures. The visible surface of the Sun is about 10,000 F - but, for reasons we don't fully understand, the corona is hundreds of times hotter, spiking up to several million degrees F. This is counterintuitive, as the Sun's energy is produced at its core.

"It's a bit like if you walked away from a campfire and suddenly got much hotter," said Fox.

Finally, Parker Solar Probe's instruments should reveal the mechanisms at work behind the acceleration of solar energetic particles, which can reach speeds more than half as fast as the speed of light as they rocket away from the Sun. Such particles can interfere with satellite electronics, especially for satellites outside of Earth's magnetic field.

To answer these questions, Parker Solar Probe uses four suites of instruments.

Parker Solar Probe will launch on a United Launch Alliance Delta IV Heavy from Cape Canaveral Air Force Station in Florida. The mission requires such a powerful launch vehicle - despite the spacecraft's relatively small size - because of the energy needed to achieve Parker Solar Probe's Sun-grazing orbit.

The FIELDS suite, led by the University of California, Berkeley, measures the electric and magnetic fields around the spacecraft. FIELDS captures waves and turbulence in the inner heliosphere with high time resolution to understand the fields associated with waves, shocks and magnetic reconnection, a process by which magnetic field lines explosively realign.

The WISPR instrument, short for Wide-Field Imager for Parker Solar Probe, is the only imaging instrument aboard the spacecraft. WISPR takes images from of structures like coronal mass ejections, or CMEs, jets and other ejecta from the Sun to help link what's happening in the large-scale coronal structure to the detailed physical measurements being captured directly in the near-Sun environment. WISPR is led by the Naval Research Laboratory in Washington, D.C.

Another suite, called SWEAP (short for Solar Wind Electrons Alphas and Protons Investigation), uses two complementary instruments to gather data. The SWEAP suite of instruments counts the most abundant particles in the solar wind -- electrons, protons and helium ions -- and measures such properties as velocity, density, and temperature to improve our understanding of the solar wind and coronal plasma. SWEAP is led by the University of Michigan, the University of California, Berkeley, and the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts.

Finally, the ISʘIS suite - short for Integrated Science Investigation of the Sun, and including ʘ, the symbol for the Sun, in its acronym - measures particles across a wide range of energies. By measuring electrons, protons and ions, ISʘIS will understand the particles' lifecycles -- wh ere they came from, how they became accelerated and how they move out from the Sun through interplanetary space. ISʘIS is led by Princeton University in New Jersey.

Parker Solar Probe is a mission some sixty years in the making. With the dawn of the Space Age, humanity was introduced to the full dimension of the Sun's powerful influence over the solar system. In 1958, physicist Eugene Parker published a groundbreaking scientific paper theorizing the existence of the solar wind. The mission is now named after him, and it's the first NASA mission to be named after a living person.

Only in the past few decades has technology come far enough (https://www.nasa.gov/feature/goddard/2018/traveling-to-the-sun-why-won-t-parker-solar-probe-melt) to make Parker Solar Probe a reality. Key to the spacecraft's daring journey are three main breakthroughs: The cutting-edge heat shield, the solar array cooling system, and the advanced fault management system.

"The Thermal Protection System (the heat shield) is one of the spacecraft's mission-enabling technologies," said Andy Driesman, Parker Solar Probe project manager at the Johns Hopkins Applied Physics Lab. "It allows the spacecraft to operate at about room temperature."

Other critical innovations are the solar array cooling system and on-board fault management systems. The solar array cooling system allows the solar arrays to produce power under the intense thermal load from the Sun and the fault management system protects the spacecraft during the long periods of time when the spacecraft can't communicate with the Earth.

Using data from seven Sun sensors placed all around the edges of the shadow cast by the heat shield, Parker Solar Probe's fault management system protects the spacecraft during the long periods of time when it can't communicate with Earth. If it detects a problem, Parker Solar Probe will self-correct its course and pointing to ensure that its scientific instruments remain cool and functioning during the long periods when the spacecraft is out of contact with Earth.

Parker Solar Probe's heat shield - called the thermal protection system, or TPS - is a sandwich of carbon-carbon composite surrounding nearly four and half inches of carbon foam, which is about 97% air. Though it's nearly eight feet in diameter, the TPS adds only about 160 pounds to Parker Solar Probe's mass because of its lightweight materials.

Though the Delta IV Heavy is one of the world's most powerful rockets, Parker Solar Probe is relatively small, about the size of a small car. But what Parker Solar Probe needs is energy - getting to the Sun takes a lot of energy at launch to achieve its orbit around the Sun. That's because any object launched from Earth starts out traveling around the Sun at the same speed as Earth - about 18.5 miles per second - so an object has to travel incredibly quickly to counteract that momentum, change direction, and go near the Sun.

The timing of Parker Solar Probe's launch - between about 4 and 6 a.m. EDT, and within a period lasting about two weeks - was very precisely chosen to send Parker Solar Probe toward its first, vital target for achieving such an orbit: Venus.

"The launch energy to reach the Sun is 55 times that required to get to Mars, and two times that needed to get to Pluto," said Yanping Guo from the Johns Hopkins Applied Physics Laboratory, who designed the mission trajectory. "During summer, Earth and the other planets in our solar system are in the most favorable alignment to allow us to get close to the Sun."

The spacecraft will perform a gravity assist to shed some of its speed into Venus' well of orbital energy, drawing Parker Solar Probe into an orbit that - already, on its first pass - carries it closer to the solar surface than any spacecraft has ever gone, well within the corona. Parker Solar Probe will perform similar maneuvers six more times throughout its seven-year mission, assisting the spacecraft to final sequence of orbits that pass just over 3.8 million miles from the photosphere.

"By studying our star, we can learn not only more about the Sun," said Thomas Zurbuchen, the associate administrator for the Science Mission Directorate at NASA HQ. "We can also learn more about all the other stars throughout the galaxy, the universe and even life's beginnings."

Parker Solar Probe is part of NASA's Living with a Star Program, or LWS, to explore aspects of the Sun-Earth system that directly affect life and society. LWS is managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland, for the Heliophysics Division of NASA's Science Mission Directorate in Washington. Johns Hopkins APL manages the Parker Solar Probe mission for NASA. APL designed and built the spacecraft and will also operate it.

Опубликовано: 27 июл. 2018 г.

Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun's blazing surface.

Temperatures in the corona -- the Sun's outer atmosphere -- spike to 3 million degrees Fahrenheit, while just 1,000 miles below, the underlying surface simmers at a balmy 10,000 F. How the Sun manages this feat is a mystery that dates back nearly 150 years, and remains one of the greatest unanswered questions in astrophysics. Scientists call it the coronal heating problem. Watch the video to learn how astronomers first discovered evidence for this mystery during an eclipse in the 1800s, and what scientists today think could explain it.

NASA's Parker Solar Probe and the Curious Case of the Hot Corona

Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches fr om the Sun's blazing surface.

Temperatures in the corona -- the tenuous, outermost layer of the solar atmosphere -- spike upwards of 2 million degrees Fahrenheit, while just 1,000 miles below, the underlying surface simmers at a balmy 10,000 F. How the Sun manages this feat remains one of the greatest unanswered questions in astrophysics; scientists call it the coronal heating problem. A new, landmark mission, NASA's Parker Solar Probe (https://www.nasa.gov/content/goddard/parker-solar-probe/) -- scheduled to launch no earlier than Aug. 11, 2018 -- will fly through the corona itself, seeking clues to its behavior and offering the chance for scientists to solve this mystery.
Fr om Earth, as we see it in visible light, the Sun's appearance -- quiet, unchanging -- belies the life and drama of our nearest star. Its turbulent surface is rocked by eruptions and intense bursts of radiation, which hurl solar material at incredible speeds to every corner of the solar system. This solar activity can trigger space weather events that have the potential to disrupt radio communications, harm satellites and astronauts, and at their most severe, interfere with power grids.

Above the surface, the corona extends for millions of miles and roils with plasma, gases superheated so much that they separate into an electric flow of ions and free electrons. Eventually, it continues outward as the solar wind, a supersonic stream of plasma permeating the entire solar system. And so, it is that humans live well within the extended atmosphere of our Sun. To fully understand the corona and all its secrets is to understand not only the star that powers life on Earth, but also, the very space around us.

A 150-year-old mystery

Most of what we know about the corona is deeply rooted in the history of total solar eclipses. Before sophisticated instruments and spacecraft, the only way to study the corona fr om Earth was during a total eclipse, when the Moon blocks the Sun's bright face, revealing the surrounding, dimmer corona.

The story of the coronal heating problem begins with a green spectral line observed during an 1869 total eclipse. Because different elements emit light at characteristic wavelengths, scientists can use spectrometers to analyze light fr om the Sun and identify its composition. But the green line observed in 1869 didn't correspond to any known elements on Earth. Scientists thought perhaps they'd discovered a new element, and they called it coronium.

Not until 70 years later did a Swedish physicist discover the element responsible for the emission is iron, superheated to the point that it's ionized 13 times, leaving it with just half the electrons of a normal atom of iron. And therein lies the problem: Scientists calculated that such high levels of ionization would require coronal temperatures around 2 million degrees Fahrenheit -- nearly 200 times hotter than the surface.

For decades, this deceptively simple green line has been the Mona Lisa of solar science, baffling scientists who can't explain its existence. Since identifying its source, we've come to understand the puzzle is even more complex than it first appeared.

"I think of the coronal heating problem as an umbrella that covers a couple of related confusing problems," said Justin Kasper, a space scientist at the University of Michigan in Ann Arbor. Kasper is also principal investigator for SWEAP, short for the Solar Wind Electrons Alphas and Protons Investigation, an instrument suite aboard Parker Solar Probe. "First, how does the corona get that hot that quickly? But the second part of the problem is that it doesn't just start, it keeps going. And not only does heating continue, but different elements are heated at different rates." It's an intriguing hint at what's going on with heating in the Sun.

Since discovering the hot corona, scientists and engineers have done a great deal of work to understand its behavior. They've developed powerful models and instruments and launched spacecraft that watch the Sun around the clock. But even the most complex models and high-resolution observations can only partially explain coronal heating, and some theories contradict each other. There's also the problem of studying the corona from afar.

We may live within the Sun's expansive atmosphere, but the corona and solar plasma in near-Earth space differ dramatically. It takes the slow solar wind around four days to travel 93 million miles and reach Earth or the spacecraft that study it -- plenty of time for it to intermix with other particles zipping through space and lose its defining features.

Studying this homogenous soup of plasma for clues to coronal heating is like trying to study the geology of a mountain, by sifting through sediment in a river delta thousands of miles downstream. By traveling to the corona, Parker Solar Probe will sample just-heated particles, removing the uncertainties of a 93-million-mile journey and sending back to Earth the most pristine measurements of the corona ever recorded.

"All of our work over the years has culminated to this point: We realized we can never fully solve the coronal heating problem until we send a probe to make measurements in the corona itself," said Nour Raouafi, Parker Solar Probe deputy project scientist and solar physicist at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland.

Traveling to the Sun is an idea older than NASA itself, but it's taken decades to engineer the technology that makes its journey possible. In that time, scientists have determined exactly what kinds of data -- and corresponding instruments -- they need in order to complete a picture of the corona and answer this ultimate of burning questions.

Explaining the corona's secrets

Parker Solar Probe will test two chief theories to explain coronal heating. The outer layers of the Sun are constantly boiling and roil with mechanical energy. As massive cells of charged plasma churn through the Sun -- much the way distinct bubbles roll up through a pot of boiling water -- their fluid motion generates complex magnetic fields that extend far up into the corona. Somehow, the tangled fields channel this ferocious energy into the corona as heat -- how they do so is what each theory attempts to explain.

One theory proposes electromagnetic waves are the root of the corona's extreme heat. Perhaps that boiling motion launches magnetic waves of a certain frequency -- called Alfvén waves -- from deep within the Sun out into the corona, which send charged particles spinning and heat the atmosphere, a bit like how ocean waves push and accelerate surfers toward the shore.

Another suggests bomb-like explosions, called nanoflares, across the Sun's surface dump heat into the solar atmosphere. Like their larger counterparts, solar flares, nanoflares are thought to result from an explosive process called magnetic reconnection. Turbulent boiling on the Sun twists and contorts magnetic field lines, building up stress and tension until they explosively snap -- like breaking an over-wound rubber band -- accelerating and heating particles in their wake.

The two theories aren't necessarily mutually exclusive. In fact, to complicate matters, many scientists think both may be involved in heating the corona. Sometimes, for example, the magnetic reconnection that sets off a nanoflare could also launch Alfvén waves, which then further heat surrounding plasma.

The other big question is, how often do these processes happen -- constantly or in distinct bursts? Answering that requires a level of detail we don't have from 93 million miles away.

"We're going close to the heating, and there are times Parker Solar Probe will co-rotate, or orbit the Sun at the same speed the Sun itself rotates," said Eric Christian, a space scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and member of the mission's science team. "That's an important part of the science. By hovering over the same spot, we'll see the evolution of heating."

Uncovering the evidence

Once Parker Solar Probe arrives at the corona, how will it help scientists distinguish whether waves or nanoflares drive heating? While the spacecraft carries four instrument suites for a variety of types of research, two in particular will obtain data useful for solving the coronal heating mystery: the FIELDS experiment and SWEAP.

Surveyor of invisible forces, FIELDS, led by the University of California, Berkeley, directly measures electric and magnetic fields, in order to understand the shocks, waves and magnetic reconnection events that heat the solar wind.

SWEAP -- led by the Harvard-Smithsonian Astrophysical Observatory in Cambridge, Massachusetts -- is the complementary half of the investigation, gathering data on the hot plasma itself. It counts the most abundant particles in the solar wind -- electrons, protons and helium ions -- and measures their temperature, how fast they're moving after they've been heated, and in what direction.

Together, the two instrument suites paint a picture of the electromagnetic fields thought to be responsible for heating, as well as the just-heated solar particles swirling through the corona. Key to their success are high-resolution measurements, capable of resolving interactions between waves and particles at mere fractions of a second.

Parker Solar Probe will swoop within 3.9 million miles of the Sun's surface -- and while this distance may seem great, the spacecraft is well-positioned to detect signatures of coronal heating. "Even though magnetic reconnection events take place lower down near the Sun's surface, the spacecraft will see the plasma right after they occur," said Goddard solar scientist Nicholeen Viall. "We have a chance to stick our thermometer right in the corona and watch the temperature rise. Compare that to studying plasma that was heated four days ago from Earth, wh ere a lot of the 3D structures and time-sensitive information are washed out."

This part of the corona is entirely unexplored territory, and scientists expect sights unlike anything they've seen before. Some think the plasma there will be wispy and tenuous, like cirrus clouds. Or perhaps it will appear like massive pipe cleaner-like structures radiating from the Sun.

"I'm pretty sure when we get that first round of data back, we'll see the solar wind at lower altitudes near the Sun is spiky and impulsive," said Stuart Bale, University of California, Berkeley, astrophysicist and FIELDS principal investigator. "I'd lay my money on the data being much more exciting than what we see near Earth."

The data is complicated enough -- and comes from multiple instruments -- that it will take scientists some time to piece together an explanation for coronal heating. And because the Sun's surface isn't smooth and varies throughout, Parker Solar Probe needs to make multiple passes over the Sun to tell the whole story. But scientists are confident it has the tools to answer their questions.

The basic idea is that each proposed mechanism for heating has its own distinct signature. If Alfvén waves are the source of the corona's extreme heat, FIELDS will detect their activity. Since heavier ions are heated at different rates, it appears that different classes of particles interact with those waves in specific ways; SWEAP will characterize their unique interactions.

If nanoflares are responsible, scientists expect to see jets of accelerated particles shooting out in opposite directions -- a telltale sign of explosive magnetic reconnection. Wh ere magnetic reconnection occurs, they should also detect hot spots wh ere magnetic fields are rapidly changing and heating the surrounding plasma.

Discoveries lie ahead

There is an eagerness and excitement buzzing among solar scientists: Parker Solar Probe's mission marks a watershed moment in the history of astrophysics, and they have a real chance of unraveling the mysteries that have confounded their field for nearly 150 years.

By piecing together the inner workings of the corona, scientists will reach a deeper understanding of the dynamics that spark space weather events, shaping conditions in near-Earth space. But the applications of this science extend beyond the solar system too. The Sun opens a window into understanding other stars -- especially those that also exhibit Sun-like heating -- stars that could potentially foster habitable environments but are too far to ever study. And illuminating the fundamental physics of plasmas could likely teach scientists a great deal about how plasmas behave elsewh ere in the universe, like in clusters of galaxies or around black holes.

It's also entirely possible that we haven't even conceived of the greatest discoveries to come. It's hard to predict how solving coronal heating will shift our understanding of the space around us, but fundamental discoveries such as this have the capacity to change science and technology forever. Parker Solar Probe's journey takes human curiosity to a never-before-seen region of the solar system, wh ere every observation is a potential discovery.

"I'm almost certain we'll discover new phenomena we don't know anything about now, and that's very exciting for us," Raouafi said. "Parker Solar Probe will make history by helping us understand coronal heating -- as well as solar wind acceleration and solar energetic particles -- but I think it also has the potential to steer the direction of solar physics' future."

Опубликовано: 25 июл. 2018 г.

The Integrated Science Investigation of the Sun--IS☉IS, pronounced ee-sis and including the symbol for the Sun in its acronym--on board Parker Solar Probe uses two complementary instruments in one combined scientific investigation to measure particles across a wide range of energies. By measuring electrons, protons and ions, IS☉IS will understand the particles' life cycles--where they came from, how they became accelerated and how they move out from the Sun through interplanetary space The two energetic particle instruments on IS☉IS are called EPI-Lo and EPI-Hi (EPI stands for Energetic Particle Instrument).

IS☉IS is led by Princeton University in Princeton, New Jersey (principal investigator David McComas), and was built largely at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, and Caltech, in Pasadena, California, with significant contributions from Southwest Research Institute in San Antonio, Texas, and NASA's Goddard Space Flight Center in Greenbelt, Maryland The IS☉IS Science Operations Center is operated at the University of New Hampshire in Durham.

NASA's Parker Solar Probe, fueled and buttoned up for liftoff Aug. 11 on the first mission to fly through the sun's corona, arrived at its launch pad at Cape Canaveral early Tuesday after a convoy trip fr om a nearby fueling and test facility.

Riding a slow-moving over-the-road transporter, the spacecraft, its solid-fueled Star 48BV upper stage, and protective aerodynamic fairing departed the Astrotech spacecraft processing facility in Titusville, Florida, late Monday for an overnight journey to the Complex 37B launch pad at nearby Cape Canaveral Air Force Station.

The convoy arrived at the launch pad before dawn Tuesday, and a heavy-lifting crane hooked to the 63-foot-tall (19-meter) fairing to hoist it atop a Delta 4-Heavy rocket, capping assembly of the launcher ahead of a predawn blastoff scheduled for Aug. 11.

The 45-minute launch window Aug. 11 opens at 3:48 a.m. EDT (0748 GMT), kicking off a 43-minute flight across the Atlantic Ocean before deployment of the 1,424-pound (646-kilogram) Parker Solar Probe spacecraft fr om the Star 48BV upper stage.
"I'm very happy to say that Solar Probe is in the fairing and ... is on top of the Delta 4-Heavy," said Nicky Fox, Parker Solar Probe's project scientist at the Johns Hopkins University Applied Physics Laboratory, which developed the mission for NASA. "It was hoisted up this morning ... I think it's fair to say that Parker Solar Probe is go for the sun."

Named for Eugene Parker, who correctly predicted the existence of the solar wind in 1958, Parker Solar Probe will head for Venus after its Aug. 11 launch, using the planet's gravity to slingshot into a tighter orbit around the sun. Assuming launch occurs Aug. 11, Parker Solar Probe will reach Venus on Oct. 2, then make its first close approach to the sun -- or perihelion -- on Nov. 5.

During its first solar encounter later this year, Parker Solar Probe will reach a distance of roughly 15 million miles (24.1 million kilometers) from the sun's surface, breaking a record set by the U.S.-German Helios 2 mission, which passed as close as 27 million miles (43.4 million kilometers) from the sun in April 1976.

Six more Venus flybys will spiral Parker Solar Probe ever-closer to the sun, redirecting the craft's trajectory toward its closest encounter with the sun at a distance of 3.83 million miles (6.16 million kilometers) in 2024, roughly 4 percent the distance of the sun from Earth.

"Venus is very important to us," Fox said. "We actually use Venus to do gravity assists. Not like other missions you've heard about that take energy from the planet to speed up, we actually generously give energy to Venus, and we use Venus to slow us down just a little bit, really to focus our orbit, almost like doing a little handbrake turn and focusing us in towards the sun. We will do 24 petal orbits, coming very close to the sun on one side, going out around the orbit of Venus on the other."

Parker Solar Probe will fly through the corona, a super-heated envelope of plasma surrounding the sun wh ere temperatures soar to millions of degrees. The temperature at the surface of the sun is hundreds of times cooler, but still a blistering 10,000 degrees Fahrenheit (6,000 degrees Celsius).

The corona is also thought by scientists to be the origin of the solar wind, a supersonic stream of charged particles flowing away from the sun in every direction, influencing the entire solar system and driving space weather.

"How is the solar wind accelerated up to millions of mph very quickly in the solar corona? The work that Dr. Parker has laid out is the foundational work for understanding this process, and this is one of the primary goals of the Parker Solar Probe," said Alex Young, associate director for science in the heliophysics division at NASA's Goddard Space Flight Center in Maryland.

"Why does this all matter? We're living in this dynamic sun's atmosphere. We're living in the solar wind streaming by the Earth, streaming by other planets," Young said. "We see the beautiful results with the aurora, but this also creates an incredibly dynamic environment that impacts our technology, makes the environment hostile for astronauts, and in the most extreme cases, can even impact technology and power grids here on Earth."

Parker Solar Probe's arrival at the launch pad is a key milestone in the $1.5 billion mission's launch campaign. In the coming days, ground crews will ensure the spacecraft is correctly attached to the Delta 4-Heavy rocket. Launch rehearsals are also on tap over the next week-and-a-half, according to Andrew Driesman, Parker Solar Probe's project manager at the Johns Hopkins University Applied Physics Laboratory.

"Picture this 63-foot-high fairing on this vehicle moving through the Cape and part of Titusville," Driesman said in an interview. "They arrive at the pad, hook it up to the crane, and lift this nearly 70-foot structure up to the top of the rocket, move it onto the top of the rocket, and then they bolt it on.

"Once we get there, after the mechanical operations are done, one of the first things we'll do is power up the spacecraft and do what we call an aliveness test," Driesman said. "That's to make sure everything was transported safely, and there are no issues with either the spacecraft or the instruments."

Launch was originally scheduled for July 31, but software reviews and snags encountered during encapsulation of the spacecraft inside the Delta 4-Heavy's payload fairing forced a delay.

The mission's launch period in August is governed by the positions of Earth and Venus in their orbits around the sun. Parker Solar Probe's interplanetary launch period was supposed to close Aug. 19, but trajectory analyses suggest the mission could depart Earth through Aug. 23 and still meet its date with Venus in early October, giving managers an extra four launch opportunities after giving up the first 11 days of the interplanetary launch period.

If further delays keep Parker Solar Probe on Earth after Aug. 23, the next chance to launch the mission will come in May 2019.

But Driesman told Spaceflight Now he is confident the mission will get off the ground in August.

"The operations are proceeding at what I would call a normal pace," he said. "There's always time built in for not getting things right. At this point, we're on track for the 11th (of August) launch date."

Parker Solar Probe's launch campaign got into full swing in April, with the arrival of the spacecraft at the Florida launch base from the Johns Hopkins University Applied Physics Laboratory on April 3. The probe's heat shield arrived a couple of weeks later, and ULA crews transferred the Delta 4-Heavy rocket to the launch pad April 16, followed the next day by the raising of the launcher vertical.

Inside the clean room at Astrotech, technicians installed Parker Solar Probe's power-generating solar arrays and heat shield over the past few months. The solar arrays have a custom design to withstand the blistering heat and sunlight the power generators will see near the sun, using a unique water cooling system to stay within temperature tolerances.

Workers also bolted on Parker Solar Probe's heat shield, a 4.5-inch thick (11.4-centimeter) piece of carbon composite that stretches around 8 feet (nearly 2.5 meters) wide. The heat shield, or thermal protection system, will take the brunt of the heat during the probe's close-up encounters with the sun, keeping most of the spacecraft -- except for the solar arrays and a few scientific sensors -- a bit above room temperature.

The spacecraft carries autonomous control software to ensure temperature-sensitive components don't get too hot, using inputs from temperature sensors to gauge wh ere the probe should be pointed. Some of the sensors failed during testing, so engineers added a redundant set to the spacecraft, according to Fox.

Parker Solar Probe's team at Astrotech loaded around 176 pounds (80 kilograms) of hydrazine into the craft's monopropellant propulsion system July 7. The probe will use the fuel and 12 tiny rocket thrusters to tweak its trajectory over its seven-year-plus mission, and help unload momentum from four spinning reaction wheels located inside the spacecraft's main body, which will control the orbiter's pointing.

Once fueled, Parker Solar Probe was lifted on top of its Star 48BV rocket motor, which will act as a third stage during launch. Fitted with a vectoring nozzle, the solid-fueled kick stage was built by Northrop Grumman Innovation Systems, formerly known as Orbital ATK.

The Star 48BV motor will fire for approximately 89 seconds after separation from the Delta 4-Heavy's second stage, giving Parker Solar Probe an extra velocity boost. The Delta 4-Heavy's triple-core first stage, powered by three RS-68A main engines producing 2.1 million pounds of thrust, will give the mission its initial lift, followed by two firings of an RL10 upper stage engine before the Star 48BV burn.

"Since we're going so close to the sun, we have to lose a lot of energy, a lot of angular momentum, associated with the Earth's orbit," said Jim Kinnison, Parker Solar Probe's mission system engineer, in an interview with Spaceflight Now. "To do that, we need a really big rocket that can provide us with a high (escape velocity). The Delta 4-Heavy was the best we could get, but even that wasn't sufficient. We still need a third stage to provide even more of a boost for us. The third stage will do that, but we're also targeting Venus for gravity assists to lose even more."

During its closest approaches in 2024 and 2025, Parker Solar Probe will experience 478 times the sunlight present at Earth, which orbits around 93 million miles (150 kilometers) from the sun. The spacecraft's velocity will jump to roughly 430,000 mph -- 120 miles per second or nearly 700,000 kilometers per hour -- during its final perihelion passages, setting a new mark for the fastest human-made object in history.

SpaceX's Falcon Heavy rocket can carry heavier cargo than the Delta 4-Heavy, but NASA would not commit to launching a high-priority science probe on an unproven booster. At the time of NASA's selection of the Delta 4-Heavy rocket for the Parker Solar Probe mission in early 2015, the Falcon Heavy was still three years from its first test flight.

With the spacecraft now on its Delta 4-Heavy launcher, the ULA and Parker Solar Probe teams plan to conduct an integrated systems test, a checkout to verify proper electrical connections between the rocket and payload. Engineers also plan to condition Parker Solar Probe's battery to maximize its lifetime, according to Driesman.

"We (will) go through basically a verification of all the flight software and parameters," Driesman said. "We'll dump every single bit off the spacecraft and compare it to what it should be, and make sure that we've got a good load of not only the flight software, but the parameters themselves."

There are also practice runs for the launch team planned. ULA's controllers already accomplished two countdown rehearsals in early July, during which they filled the Delta 4-Heavy with liquid hydrogen and liquid oxygen, then drained the cryogenic propellants from the rocket.

Technicians will also enter the Delta 4-Heavy's payload shroud to take off "remove-before-flight" covers protecting sensitive scientific instrumentation.

"We do some further launch rehearsals to make sure the team is as ready as the spacecraft is," Driesman said. "And then we'll go into the fairing. There are just a few red tag covers on-board that cover some sensitive instruments. We'll crawl into the fairing and remove the red tag covers, and then we're pretty much, at that point, ready to launch."

Зонд Паркера
©  NASA/Johns Hopkins APL/Ed Whitman (https://nasa.gov/)

ВАШИНГТОН, 1 августа. /Корр. ТАСС Дмитрий Кирсанов/. Специалисты Национального управления США по аэронавтике и исследованию космического пространства (NASA) установили на ракету-носитель автоматическую межпланетную станцию, предназначенную для исследования Солнца. Об этом сообщила во вторник на брифинге для журналистов координатор этого проекта NASA Никола Фокс.

"Я чрезвычайна счастлива сказать, что зонд заключен в обтекатель. По состоянию на полдень сегодняшнего дня <...> обтекатель установлен на верхушку тяжелой ракеты Delta IV. Он был поднят этим утром. <...> Зонд Паркера готов лететь к Солнцу", - заявила специалист из Лаборатории прикладной физики Университета Джонса Гопкинса.

Стартовое окно для запуска станции открывается 11 августа. Закрывается оно 19 августа. Дата старта несколько раз сдвигалась за последние недели, в том числе для дополнительного тестирования программного обеспечения систем зонда.

Последние приготовления
Весной аппарат был переброшен к космодрому на мысе Канаверал (штат Флорида), с которого ему предстоит стартовать.

В ночь со 2 на 3 апреля зонд был перевезен из входящего в структуру NASA Центра космических полетов имени Годдарда в Гринбелте (штат Мэриленд) на расположенную поблизости базу ВВС и ВМС США Эндрюс. Оттуда аппарат на борту военно-транспортного самолета C-17 доставили на сборочное предприятие компании Astrotech Space Operations, соседствующее с космодромом на мысе Канаверал. Затем зонд со всей предосторожностью извлекли из контейнера, в котором он перебрасывался из Мэриленда во Флориду.

На объекте фирмы Astrotech Space Operations у космодрома на мысе Канаверал станция проходила последние всеобъемлющие испытания. Именно там ее "упаковали" в специальное термозащитное покрытие, укрыли обтекателем и установили на носителе.

Условия, "приближенные к боевым"

С января на протяжении почти двух месяцев станцию подвергали температурным испытаниях в вакууме. Эти тесты шли в Центре имени Годдарда, где зонд, который по размерам сопоставим с небольшим автомобилем, поместили в вакуумную камеру высотой примерно 12 м.

Инженеры сначала проверяли, выдерживают ли зонд и его "начинка" низкую температуру - до минус 292 градусов Фаренгейта (минус 180 Цельсия). Затем ее постепенно увеличивали, чтобы посмотреть, как на станцию воздействует экстремально высокая температура. Потом специалисты чередовали такой перепад температур, имитируя условия полета в космическом пространстве.

Детали миссии

Планируется, что в ноябре зонд приблизится к Солнцу на расстояние в 6,4 млн км. Это означает, что аппарат будет находиться в пределах короны Солнца, то есть внешних слоев его атмосферы, где температура может достигать 500 тыс. кельвинов (около 500 тыс. градусов Цельсия) и даже нескольких миллионов кельвинов.

По замыслу американских ученых, в период по июнь 2025 года зонд совершит 24 витка по орбите вокруг Солнца, разгоняясь до скорости 724 тыс. км в час. На каждый такой виток у него будет уходить 88 дней.

На борту аппарата стоимостью порядка $1,5 млрд будет находиться четыре комплекта научных инструментов. При помощи этой аппаратуры специалисты рассчитывают, в частности, осуществить различные измерения солнечной радиации. Наряду с этим зонд должен будет передать фотоснимки, которые станут первыми, сделанными в пределах солнечной короны. Оборудование зонда будет защищено оболочкой из углепластика толщиной 11,43 см, позволяющей выдержать температуру до примерно 1,4 тыс. градусов Цельсия.

Как признала в июне прошлого года Никола Фокс, проект удалось реализовать только теперь благодаря появлению новых материалов, использованных в первую очередь при создании термостойкого щита зонда. Станция получит и новые панели солнечных батарей, уточнила Фокс. "Мы наконец прикоснемся к Солнцу", - эмоционально сказала о курируемом проекте эксперт. По ее выражению, зонд поможет ученым понять, "как работает Солнце".

Значение проекта

NASA обещает, что миссия произведет революцию в представлении человека о процессах, протекающих на Солнце. Претворение в жизнь намеченных планов позволит внести "фундаментальный вклад" в понимание причин "нагревания солнечной короны", а также возникновения солнечного ветра (потока ионизированных частиц, истекающего из солнечной короны) и "ответить на критически важные вопросы в гелиофизике, которые уже на протяжении нескольких десятилетий имеют высший приоритет", убеждено NASA. Информация с борта аппарата, по мнению его специалистов, будет иметь огромную ценность и с точки зрения подготовки дальнейших пилотируемых полетов за пределы Земли, поскольку позволит прогнозировать "радиационную обстановку, в которой предстоит работать и жить будущим покорителям космоса".

Зонд назван в честь американского астрофизика Юджина Паркера, которому минувшим летом исполнилось 90 лет. Несмотря на свой возраст, он до сих пор ведет научную деятельность в Университете Чикаго (штат Иллинойс).

Паркер стал одним из первых в мире специалистов, занимавшихся исследованиями солнечного ветра. С 1967 года он является членом Национальной академии наук США.

Предполагается, что зонд Паркера подлетит в семь раз ближе к Солнцу, чем какой-либо другой из космических аппаратов, ранее отправлявшихся человеком.

ЦитатаPrinceton in space: Meet ISʘIS, heading to touch the sun

Liz Fuller-Wright, Office of Communications
July 30, 2018 10 a.m.


Within the next month, NASA's Parker Solar Probe will lift off fr om Cape Canaveral, heading for a rendezvous with the sun. Onboard will be ISʘIS, an instrument suite led by Princeton's David McComas to measure energetic particles fr om the sun's corona and the solar wind.

McComas, a professor of astrophysical sciences (https://web.astro.princeton.edu/) and the vice president of the Princeton Plasma Physics Laboratory (https://www.pppl.gov/), is the principal investigator for the ISʘIS mission. The Integrated Science Investigation of the Sun uses the symbol of the sun (ʘ) in the middle of its acronym, which is pronounced like the Egyptian goddess Isis is pronounced in Arabic: "EEE-sys." By measuring electrons, protons and ions, ISʘIS will equip researchers to understand the particles' lifecycles -- where they originate, how they are accelerated, and how they move out fr om the sun through interplanetary space. 

Parker Solar Probe, with a launch window between Aug. 11 and 19, is designed to plunge repeatedly into the innermost regions of the solar system wh ere the sun's million-degree atmosphere, or corona, begins its outward expansion to produce the supersonic solar wind. At its closest approach, it will be less than 4 million miles away from the surface of the sun, inside the sun's atmosphere, measuring and sampling particles in situ.
It will pass close enough to the sun to watch the solar wind speed up from subsonic to supersonic, and it will fly though the birthplace of the highest-energy solar particles. In addition, Parker Solar Probe will be the fastest human-made object ever, traveling at 430,000 miles per hour. That's fast enough to get from Princeton to New York City in half a second.

"It's a super exciting mission," said McComas. "Almost everybody has seen an eclipse, or at least an eclipse picture, and you see that hairy stuff around the sun when it's blocked by the moon -- that's the corona. Our spacecraft will fly inside the corona, just incredibly close, and do it over and over and over again, so you can sample different solar wind environments. The sun is highly variable, so solar wind can be really fast, or slow, with transient solar particle events or more steady fluxes, so having lots and lots of re-visits is really great for the science."

EPI-Lo is one of the two instruments that make up ISʘIS, an instrument suite on NASA's Parker Solar Probe, which will pass closer to the sun than any mission in human history. ISʘIS will take dozens of passes through the sun's million-degree atmosphere, or corona, wh ere EPI-Lo's 80 tiny openings will measure the spectra of the lower-energy particles streaming from the sun.

Measurements from the ISʘIS instruments will allow McComas' team of researchers to explore energetic particles dynamics, including their origins, their acceleration as they are buffeted by the shockwaves and turbulence of the solar atmosphere, and their transport from the corona out to the heliosphere (https://www.princeton.edu/news/2018/07/18/princetons-mccomas-will-lead-imap-nasa-mission-study-heliosphere), the bubble-shaped region that surrounds the solar system.

The two ISʘIS Energetic Particle Instruments measure lower (EPI-Lo) and higher (EPI-Hi) energy particles. EPI-Lo has 80 tiny openings that sample nearly a complete hemisphere, measuring ions and ion composition from about 20 keV/nucleon-15 MeV total energy and electrons from about 25-1000 keV. "To be able to instantaneously view such particles over half the sky, basically, has never been done before," said McComas.

"This is not a spinning spacecraft, so it's hard to get a big field of view," he said. "You can't predict exactly wh ere the particles will be coming in. We want to measure the distribution of particles that come in different intensities, from different directions."

EPI-Lo measures the spectra of electrons and ions and identifies carbon, oxygen, neon, magnesium, silicon, iron and two isotopes of helium, He-3 and He-4. Distinguishing between helium isotopes will help determine which of several theorized mechanisms caused the particles' acceleration.

An ion that enters EPI-Lo through one of the 80 dime-sized openings passes through two carbon-polyimide-aluminum foils before encountering a solid-state detector. Upon impact, the foils produce electrons that are measured by a microchannel plate. The sensors can identify the species of the particles by using the amount of energy left by the ion's impact on the detector and the time it takes the ions to pass through the sensors.

EPI-Hi combines three particle sensors composed of stacked layers of detectors to measure ions from about 1-200 MeV/nucleon and electrons from about 0.5-6 MeV. It uses a series of ultra-thin silicon wafers to detect the trajectory of the particles and their species. At the probe's closest approach to the sun, EPI-Hi will be able to detect up to 100,000 particles per second.

These high-energy particles are moving incredibly fast, McComas said. They are much, much faster than the satellite, which will be whipping through space at almost half a million miles per hour. Considering how much faster the energetic particles are, "We're effectively standing still," he said. Counting and measuring solar energetic particles is less like scooping up pebbles than like sampling rain as a hurricane blows past, or measuring dust as a tornado whirls by.

EPI-Hi, the other instrument making up ISʘIS, combines three particle sensors to detect the trajectory and species of high-energy particles ejected from the sun. At its closest approach to the sun, EPI-Hi will be able to detect up to 100,000 particles per second.

EPI-Hi has evolved from a tried-and-true design, said McComas, and EPI-Lo is even more innovative.

"It's a really interesting balancing act," he said. "New designs have some risk to them, but you absolutely cannot fail in space. It's not like any other area. You can't go fix it, so it's got to work right, and you have to have really tight system engineering -- but if you're not taking some level of risk in your design and development and your measurements, you're not pushing the forefront of science."

ISʘIS is also designed to reveal previously unknown features of the inner heliosphere, which stretches from the sun's corona out to the orbit of Mercury. ISʘIS instruments will observe continuously when the spacecraft is within 23 million miles of the sun (0.25 AU) with a high data collection rate. When it is farther from the sun, it will operate in a low-rate science mode whenever it can, to capture as complete a record as possible of the solar energetic particle environment and provide calibration and continuity for measurements closer in to the sun.

Together, ISʘIS' unique observations will enable scientists to discover, untangle and understand the important physical processes that govern energetic particles in the innermost regions of our heliosphere, for the first time.

"A lot of what we haven't been able to understand about these energetic particles has to do with the fact that we're so far from the source," McComas said. "It's hard for us to disentangle effects from the source versus acceleration and transport processes." He described a solar storm observed in 1980 by the Helios-1 spacecraft, located about halfway between the Earth and the sun, which detected five distinct bursts of electrons and helium ions, while another instrument near Earth only detected a single particle event.

"Understanding energetic particles is really important, not just scientifically, but also because they affect space weather, which can impact GPS, telecommunications, and all kinds of practical things," McComas said. "They can destroy the functioning of spacecraft in orbit. They also cause the aurora borealis, which are beautiful to see, but when they're raining on a spacecraft, it's less good."

By disentangling the complicated questions around the origin, acceleration and transport of solar energetic particles, ISʘIS will "help us be much smarter about looking at energetic particle data measured near Earth and interpreting what it means back on the sun, how the particles got there, and how to deal with them as a part of space weather," McComas said. "This is a really critical mission."

NASA's Parker Solar Probe, secured inside its payload fairing, was moved July 30, 2018, from nearby Astrotech Space Operations in Titusville, Florida, to Space Launch Complex 37 on Cape Canaveral Air Force Station. The following day, the spacecraft was lifted and attached to the top of the United Launch Alliance Delta IV Heavy rocket in the Vertical Integration Facility.

Parker Solar Probe is being prepared for its launch, on its mission to "touch" the Sun. The spacecraft will travel directly into the Sun's atmosphere, about 4 million miles from its surface -- and more than seven times closer than any spacecraft has come before, thanks to its innovative Thermal Protection System. The mission will perform the closest-ever observations of a star when it travels through the Sun's outer atmosphere, called the corona. The mission will rely on measurements and imaging to revolutionize our understanding of the corona and how processes there ultimately affect near-Earth space.

ЦитатаReady for Its Day in the Sun: The SWEAP Investigation

Release No.: 2018-15
For Release: Friday, August 3, 2018 - 1:00pm

(https://www.cfa.harvard.edu/sites/www.cfa.harvard.edu/files/styles/width720/public/images/pr//2018-15.jpg?itok=-LEmtPsQ)

Cambridge, MA - When NASA's Parker Solar Probe launches into space from the Kennedy Space Center, it will begin its journey to the Sun, our nearest star. The Parker Solar Probe will travel almost 90 million miles and eventually enter through the Sun's outer atmosphere to encounter a dangerous environment of intense heat and solar radiation. During this harrowing journey, it will fly closer to the Sun than any other human-made object.

To revolutionize our understanding of our most important and life-sustaining star, scientists and engineers have built a suite of instruments aboard the Parker Solar Probe to conduct different experiments. Some of these instruments will be protected by a thick carbon-composite heat shield. However, others will be more exposed.

The Solar Wind Electrons Alphas and Protons (SWEAP) investigation is the set of instruments that will directly measure the hot ionized gas in the solar atmosphere during the solar encounters. A key instrument on SWEAP called the Solar Probe Cup (SPC) was built at the Smithsonian Astrophysical Observatory (SAO) in Cambridge, Mass.
The SPC is a small metal device that will peer around the protective heat shield of the spacecraft directly at the Sun. It will face some of the most extreme conditions ever encountered by a scientific instrument, and allow a sample of the Sun's atmosphere to be swept up for the first time.

The SPC uses high voltages to determine what type of particles can enter, which is a way of measuring the energy of the particle. This is crucial information for probing the wind of hot ionized gas that is constantly produced by the Sun. As the spacecraft flies towards the Sun for an encounter, the wind is directed straight into the cup. Without the SPC, Parker Solar Probe would miss most of what is in between Earth and the Sun. This unique probe of the solar wind is important for scientists to better understand space weather, which is responsible for effects that range from endangering astronauts on space walks to impacting the electronics in communications satellites.

The Parker Solar Probe spacecraft, about the size of a small car, will travel towards the Sun's atmosphere at speeds of about 430,000 mph (700,000 km/hr), becoming the fastest human-made object. Eventually, Parker Solar Probe will enter an orbit that approaches to within only 4 million miles from the star's surface. (For context, the Earth averages a distance of about 93 million miles from the Sun during its elliptical orbit. Or, to put it another way, the spacecraft will travel about 96% of the way from the Earth to the Sun.) Parker Solar Probe, which will be carried into space by a Delta-IV Heavy rocket, is currently scheduled to launch on August 11, 2018.

The SWEAP Team is led by Justin Kasper currently at the University of Michigan (and currently an SAO Research Associate). On the SWEAP Investigation, SAO partners with team members from University of California, Berkeley Space Sciences Laboratory, the NASA Marshall Space Flight Center, the University of Alabama Huntsville, NASA Goddard Space Flight Center, Los Alamos National Laboratory, and the Massachusetts Institute of Technology. SAO built the SPC (Instrument Scientist: Tony Case), leads the Science Operations Center (Head of Science Operations: Kelly Korreck), and manages the overall SWEAP program.

It also carries four suites of advanced instruments (https://t.umblr.com/redirect?z=https%3A%2F%2Fwww.nasa.gov%2Fcontent%2Fgoddard%2Fparker-solar-probe-instruments&t=YTQ4NjRjMDgyZGQ3NzMxMjcyYTk2NjhhZWZlNGRhYWE1NWUyNWY4NSxOc1JSWDlqOQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F176450633409%2Ftools-of-the-trade-how-parker-solar-probe-will&m=0) designed to study the Sun in a multitude of ways.  

1. Measuring particles

Two of Parker Solar Probe's instrument suites are focused on measuring particles - electrons and ions - within the corona.

One of these particle-measuring instrument suites is SWEAP (Solar Wind Electrons Alphas and Protons). SWEAP (https://t.umblr.com/redirect?z=https%3A%2F%2Fwww.nasa.gov%2Fcontent%2Fgoddard%2Fparker-solar-probe-instruments&t=YTQ4NjRjMDgyZGQ3NzMxMjcyYTk2NjhhZWZlNGRhYWE1NWUyNWY4NSxOc1JSWDlqOQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F176450633409%2Ftools-of-the-trade-how-parker-solar-probe-will&m=0) counts the most common particles in the solar wind (https://t.umblr.com/redirect?z=https%3A%2F%2Fwww.nasa.gov%2Ffeature%2Fgoddard%2F2018%2Fparker-solar-probe-and-the-birth-of-the-solar-wind&t=OGIzZjAzYTk5ZTcyNzU0YWUwOGU3YjljOGIzZjYyODdlOWI1MDdmNCxOc1JSWDlqOQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F176450633409%2Ftools-of-the-trade-how-parker-solar-probe-will&m=0) - the Sun's constant outflow of material - and measures their properties, like velocity, density and temperature. Gathering this information about solar wind particles will help scientists better understand why the solar wind reaches supersonic speeds and exactly which part of the Sun the particles come fr om.

One instrument in the SWEAP suite is the Solar Probe Cup. Most of the instruments on Parker Solar Probe stay safe and cool in the shadow of the heat shield, but the Solar Probe Cup is one of the few that sticks out. That's so it can capture and measure particles streaming straight out from the Sun, and it had to go through some intense testing (https://t.umblr.com/redirect?z=https%3A%2F%2Fnews.umich.edu%2Fkey-parker-solar-probe-sensor-bests-sun-simulator-last-launch-hurdle%2F&t=ZmNhNzFmODliNzJhNzQ3YjM3NmMwZTE5NzA1MzQ3MjhmOTM5NTg5MSxOc1JSWDlqOQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F176450633409%2Ftools-of-the-trade-how-parker-solar-probe-will&m=0) to get ready for this position in the Sun's incredibly hot corona.

The ISʘIS suite (pronounced EE-sis, and including the symbol for the Sun in its acronym) also measures particles. ISʘIS (https://t.umblr.com/redirect?z=https%3A%2F%2Fwww.nasa.gov%2Fcontent%2Fgoddard%2Fparker-solar-probe-instruments&t=YTQ4NjRjMDgyZGQ3NzMxMjcyYTk2NjhhZWZlNGRhYWE1NWUyNWY4NSxOc1JSWDlqOQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F176450633409%2Ftools-of-the-trade-how-parker-solar-probe-will&m=0) is short for Integrated Science Investigation of the Sun, and this instrument suite measures particles that move faster - and therefore have more energy - than the solar wind.

These measurements will help scientists understand these particles' lifecycles - wh ere they came from, how they got to be traveling so fast (these particles can reach speeds more than half the speed of light!) and what path they take as they travel away from the Sun and into interplanetary space.

2. Taking pictures - but not of the Sun's surface.

WISPR (Wide-Field Imager for Parker Solar Probe) has the only two cameras on Parker Solar Probe - but they're not pointed directly at the Sun. Instead, WISPR (https://t.umblr.com/redirect?z=https%3A%2F%2Fwww.nasa.gov%2Fcontent%2Fgoddard%2Fparker-solar-probe-instruments&t=YTQ4NjRjMDgyZGQ3NzMxMjcyYTk2NjhhZWZlNGRhYWE1NWUyNWY4NSxOc1JSWDlqOQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F176450633409%2Ftools-of-the-trade-how-parker-solar-probe-will&m=0) looks out the side of the spacecraft, in the direction it's traveling, looking at the space Parker Solar Probe is about to fly through. From that vantage point, WISPR captures images of structures within the corona like coronal mass ejections, or CMEs. CMEs are clouds of solar material that occasionally explode from the Sun at millions of miles per hour. Because this solar material is magnetized, CMEs can trigger geomagnetic storms when they reach Earth - which, in turn, can cause effects like auroras and even, in extreme cases, power outages (https://t.umblr.com/redirect?z=https%3A%2F%2Fwww.nasa.gov%2Ffeature%2Fgoddard%2F2016%2Fnasa-helps-power-grids-weather-geomagnetic-storms&t=NzMyM2FiYTM0ZmI5ODZlMGI0YmU3YWI1NmE0MzZhYmIwOThjZTc4NSxOc1JSWDlqOQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F176450633409%2Ftools-of-the-trade-how-parker-solar-probe-will&m=0).

Right now, our observations of events like these come from satellites orbiting near Earth, so WISPR will give us a whole new perspective. And, scientists will be able to combine WISPR's images with Parker Solar Probe's direct particle measurements to get a better idea of how these structures change as they travel.

3. Studying electric & magnetic fields

The FIELDS instrument suite is appropriately named: It's what scientists will use to study the electric and magnetic fields in the corona.

Electric and magnetic fields are key to understanding what happens, not only on the Sun, but throughout space, because they are the primary driver accelerating charged particles. In particular, a process called magnetic reconnection (https://nasa.tumblr.com/post/144300595759/exploring-the-invisible-magnetic-reconnection) - when magnetic field lines explosively realign, sending particles rocketing away at incredible speeds - is thought to drive solar explosions, as well as space weather effects on Earth, like the aurora.

FIELDS (https://t.umblr.com/redirect?z=https%3A%2F%2Fwww.nasa.gov%2Fcontent%2Fgoddard%2Fparker-solar-probe-instruments&t=YTQ4NjRjMDgyZGQ3NzMxMjcyYTk2NjhhZWZlNGRhYWE1NWUyNWY4NSxOc1JSWDlqOQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F176450633409%2Ftools-of-the-trade-how-parker-solar-probe-will&m=0) measures electric and magnetic field at high time resolution, meaning it takes lots of measurements in a short amount of time, to track these processes and shed some light on the mechanics underlying the Sun's behavior. FIELDS' measurements are precisely synced up with those of the SWEAP suite (one of the sets of instruments studying particles) so that scientists can match up the immediate effects that electric and magnetic fields have on the material of the solar wind.

ЦитатаSpace probe to plunge into fiery corona of the sun

By Robert Sanders (mailto:rlsanders@berkeley.edu?subject=RE:%20Space%20probe%20to%20plunge%20into%20fiery%20corona%20of%20the%20sun), Media relations | AUGUST 6, 2018

On August 11, NASA plans to launch Earth's first spacecraft to venture inside the orbits of Venus and Mercury to touch the very edge of the sun's fiery corona.

Outfitted with instruments designed and built at the University of California, Berkeley, the Parker Solar Probe will achieve a goal that space scientists have dreamed about for decades: to get close enough to the sun to learn how the turbulent surface we see fr om Earth dumps its energy into the corona and heats it to nearly 2 million degrees Fahrenheit, spawning the solar wind that continually bombards our planet.

(Applied Physics Laboratory video, Johns Hopkins University)

"This is a piece of heliophysics science we all really wanted for a long time, since the 1950s," said Stuart Bale (http://physics.berkeley.edu/people/faculty/Stuart-Bale), a UC Berkeley professor of physics, former director of the campus's Space Sciences Laboratory and one of four principal investigators for the instruments aboard the mission. "For me personally, I've been working on the probe since it was approved in 2010, but I really spent a large part of my career getting ready for it."

The solar probe will travel faster than any spacecraft in history, at its peak reaching 430,000 miles per hour, and will be only four-and-a-half solar diameters, or 3.8 million miles, above the solar surface at its closet approach to the sun around 2024. The probe is equipped with a heat shield to protect its sensors fr om the sun's heat, which could reach 2,500 degrees Fahrenheit, nearly hot enough to melt steel.

At this distance, the solar probe will be within a region wh ere electrons and ionized atoms - mostly hydrogen ions, or protons, and helium ions, called alpha particles - are accelerated and shot out toward the planets at high speed.

When these ions, called the solar wind, hit Earth, they interact with Earth's magnetic fields and generate the northern and southern lights as well as storms in the outermost atmosphere that interfere with radio communications and satellite operations. Accelerated to higher speeds, so-called "solar energetic" particles can pose a hazard to astronauts.

Scientists still do not know how the solar wind ions are accelerated, or why the ions and electrons in the corona are so much hotter, about 1.7 million degrees Fahrenheit, than the surface of the sun, which is a relatively cool 10,000 degrees Fahrenheit. The Parker Solar Probe could answer those questions, and help scientists on Earth forecast the large eruptions from the sun that pose the greatest peril to our spacecraft and communications systems.

Follow the magnetic fields

FIELDS, a suite of instruments built at UC Berkeley's Space Sciences Laboratory, is one of four instrument packages aboard the probe. With the help of a six-foot boom projecting in the direction the spacecraft is moving, it will measure the electric and magnetic fields in the corona, which will tell scientists the total energy streaming outward from the sun.

In defiance of all logic, the sun's atmosphere gets much, much hotter farther from its blazing surface. Learn how astronomers first discovered evidence for this mystery during an eclipse in the 1800s, and what scientists today think could explain it. (NASA Godddard video)

These measurements will test one theory of how the sun heats the corona: by jiggling the magnetic field lines. The strong magnetic field of the sun stretches out far into space, but the magnetic field lines are anchored in surface regions that constantly move around because of convection below, like boiling water. The constant movement of the base of the magnetic field lines creates waves that travel outward along the lines, just as jiggling the end of a long rope sends waves to the other end. Somehow, these so-called Alfvén waves accelerate particles to high speeds and fling them into space.

"If the wave-driven model is correct, then I think our measurements will be the fundamental measurements on the mission," Bale said.

The other popular theory is that tiny flares called nanoflares all over the surface of the sun produce magnetic fields that cross, reconnect and fling disconnected loops of magnetic field into space, accelerating ions along with it. This was first proposed in 1987 by Eugene Parker, after whom the solar probe is named. Now 91, Parker predicted the existence of and named the solar wind in the 1950s.

Radio antennas on the FIELDS package will look for radio waves created by nanoflares, which have yet to be detected, while another package of instruments, SWEAP (Solar Wind Electrons Alphas and Protons), will record the speed of solar wind electrons, protons and alpha particles as they whiz by the probe. Correlating nanoflare or microflare activity with the flux of particles streaming from the sun could confirm the magnetic reconnection theory. SWEAP is led by the University of Michigan and the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, though much of the instrument was designed and built at the Space Sciences Laboratory at UC Berkeley.

The surface of the sun, or photosphere, is about 10,000 degrees Fahrenheit, but the region through which the solar probe flies, the corona, is 2 million degrees. Scientists want to know why. (NASA image)

Two other instrument packages will be aboard the probe. WISPR, the Wide-Field Imager for Parker Solar Probe, was built at the Naval Research Laboratory and will capture visible-light images of the sun's corona directly in front of the orbiting probe. ISʘIS (pronounced E-sis) - short for Integrated Science Investigation of the Sun, and including ʘ, the symbol for the Sun, in its acronym - is led by Princeton University and will measure the energy and identity of energized electrons and ions, including ions heavier that hydrogen and helium, in order to find out how they are sometimes accelerated to nearly light speed close to the sun.

Together, these instruments should be able to record the speed-up of the solar wind from subsonic to supersonic and the birth of the highest-energy solar particles.

"Plasma physics is really hard to study in the laboratory," said Bale, who focuses on the role of magnetic fields and ionized plasma in space, in particular around stars like the sun. "Sticking a spacecraft right in the hot plasma makes an ideal laboratory."

Looping around Venus

This probe is the chance of a lifetime for Bale. Though his team will deploy booms and test instrument functions one day after launch, most of the instruments will then be turned off and won't begin taking real measurements of the corona until the probe reaches its first close approach to the sun in November.

(https://news.berkeley.edu/wp-content/uploads/2018/08/aplguypspthird900.jpg) (https://news.berkeley.edu/wp-content/uploads/2018/08/aplguypspthird900.jpg)

After a loop around Venus to slow down, the probe will get the closest any spacecraft has ever been to the sun, a distance from the center of the sun equal to 36 times the sun's radius (36 solar radii). Venus orbits at 155 solar radii and Mercury at 83 solar radii.

Over the next six years, the probe will loop around Venus six more times, gradually working its way to approximately 9.8 solar radii from the center of the sun. There, it will be well within the corona, at the outer edge of which particles exceed the speed of sound - the Alfvén speed, which is about 200 miles per second - and no longer call the sun home.

"The goal of the mission is to get inside that transition region, so we get into the real corona wh ere the flow is subAlfvénic," Bale said. "We think that boundary is at about 15 solar radii, so we probably won't start hitting it until 2021."

Once inside the corona, the probe may see the jiggling magnetic field lines, or Alfvén waves, bouncing back and forth between the sun's surface and the edge of the corona, a turbulent cascade that may be the feedback loop that accelerates particles to the high speeds seen in the solar wind.

"In early December, I am counting on having that first pass of data at 35 solar radii, and I am sure it will be revolutionary. There will be great new stuff in there, from what we know about previous missions," Bale said.

Over its seven-year mission lifetime, the probe will dip into the sun's inner atmosphere 24 times. As part of NASA's outreach efforts, more than 1.1 million people submitted their names to be recorded on a memory card that will accompany the spacecraft around the sun.

The probe is scheduled for launch in the early hours of Monday, Aug. 11, from Cape Canaveral Air Force Station in Florida, aboard a United Launch Alliance Delta IV Heavy rocket with an upper stage to boost it out of Earth orbit toward Venus.

Since the mission was approved in 2010, some 40 to 50 people at Berkeley's Space Sciences Laboratory have worked on the solar probe. Through the formal end of the mission in 2026, and including subsequent data analysis, UC Berkeley will have received about $100 million out of a total of $1.5 billion spend on the mission.

Parker Solar Probe will provide unprecedented information about our Sun, where changing conditions can spread out into the solar system to affect Earth and other worlds. The spacecraft will fly directly into the Sun's atmosphere wh ere, from a distance of - at the closest approach -- approximately 4 million miles from its surface, the spacecraft will trace how energy and heat move through the Sun's atmosphere and explore what accelerates the solar wind and solar energetic particles.

The agency is holding a prelaunch mission briefing Thursday, Aug. 9, at 1 p.m. The briefing will be broadcast live on NASA Television and at http://www.nasa.gov/live. Live launch coverage will begin Saturday, Aug. 11, at 3 a.m. For a complete schedule of mission coverage, including opportunities for media participation, visit https://www.nasa.gov/press-release/parker-solar-probe-briefings-and-events.

Parker Solar Probe Briefings and Events

NASA's Parker Solar Probe (https://www.nasa.gov/parker), a historic mission that will revolutionize our understanding of the Sun, is scheduled to launch on Saturday, Aug. 11. The first launch opportunity is at 3:33 a.m. EDT, at the opening of a 65-minute window. The spacecraft will launch on a United Launch Alliance Delta IV Heavy rocket fr om Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida. The deadline for media to apply for accreditation for this launch has passed.

Launch coverage will begin on NASA Television and the agency's website (http://www.nasa.gov/live) at 3:00 a.m. EDT.

Parker Solar Probe, protected by a first-of-its-kind heat shield and other innovative technologies, will provide unprecedented information about our Sun, where changing conditions can spread out into the solar system to affect Earth and other worlds. The spacecraft will fly directly into the Sun's atmosphere wh ere, from a distance of - at the closest approach -- approximately 4 million miles from its surface, the spacecraft will trace how energy and heat move through the Sun's atmosphere and explore what accelerates the solar wind (https://solarscience.msfc.nasa.gov/SolarWind.shtml) and solar energetic particles (https://helios.gsfc.nasa.gov/sep.html).

Parker Solar Probe is part of NASA's Living with a Star (https://science.nasa.gov/heliophysics/programs/living-with-a-star) Program, managed by the agency's Goddard Space Flight Center in Greenbelt, Maryland, for NASA's Science Mission Directorate in Washington. The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, designed, built and manages the mission for NASA.

ЦитатаIt's Surprisingly Hard to Go to the Sun

NASA Goddard (https://www.youtube.com/channel/UCAY-SMFNfynqz1bdoaV8BeQ)

Опубликовано: 8 авг. 2018 г.

The Sun contains 99.8 of the mass in our solar system. Its gravitational pull is what keeps everything here, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion miles away. But even though the Sun has such a powerful pull, it's surprisingly hard to actually go to the Sun: It takes 55 times more energy to go to the Sun than it does to go to Mars.

Why is it so difficult? The answer lies in the same fact that keeps Earth from plunging into the Sun: Our planet is traveling very fast - about 67,000 miles per hour - almost entirely sideways relative to the Sun. The only way to get to the Sun is to cancel that sideways motion.

Since Parker Solar Probe will skim through the Sun's atmosphere, it only needs to drop 53,000 miles per hour of sideways motion to reach its destination, but that's no easy feat. In addition to using a powerful rocket, the Delta IV Heavy, Parker Solar Probe will perform seven Venus gravity assists over its seven-year mission to shed sideways speed into Venus' well of orbital energy. These gravity assists will draw Parker Solar Probe's orbit closer to the Sun for a record approach of just 3.83 million miles from the Sun's visible surface on the final orbits.

Though it's shedding sideways speed to get closer to the Sun, Parker Solar Probe will pick up overall speed, bolstered by Sun's extreme gravity - so it will also break the record for the fastest-ever human-made objects, clocking in at 430,000 miles per hour on its final orbits.

ЦитатаParker Solar Probe Proceeds Toward Launch Aug. 11

Linda Herridge (https://blogs.nasa.gov/parkersolarprobe/author/lherridg/)
Posted Aug 9, 2018 at 11:06 am


The Parker Solar Probe mission and launch teams today concluded a successful Launch Readiness Review. There are no technical issues being worked at this time. Teams are proceeding for liftoff on Saturday, Aug. 11, at 3:33 a.m. EDT. On a United Launch Alliance Delta IV Heavy rocket with NASA's Parker Solar Probe.

Parker Solar Probe will provide unprecedented information about our Sun, where changing conditions can spread out into the solar system to affect Earth and other worlds. The spacecraft will fly directly into the Sun's atmosphere where, from a distance of - at the closest approach -- approximately 4 million miles from its surface, the spacecraft will trace how energy and heat move through the Sun's atmosphere and explore what accelerates the solar wind and solar energetic particles.

Meteorologists with the U.S. Air Force 45th Space Wing are predicting a 70 percent chance of favorable weather on launch day. Primary weather concerns are anvil clouds and cumulus clouds.

ЦитатаParker Solar Probe Instruments: SWEAP

JHU Applied Physics Laboratory (https://www.youtube.com/channel/UCz4r-ikQdWEj1gG1aFJTy-g)

Опубликовано: 7 авг. 2018 г.

The Solar Wind Electrons Alphas and Protons investigation, or SWEAP, gathers observations using two complementary instruments: the Solar Probe Cup, or SPC, and the Solar Probe Analyzers, or SPAN. The instruments count the most abundant particles in the solar wind -- electrons, protons and helium ions -- and measure such properties as velocity, density, and temperature to improve our understanding of the solar wind and coronal plasma. SWEAP was built mainly at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, and at the Space Sciences Laboratory at the University of California, Berkeley. The institutions jointly operate the instrument. The principal investigator is Justin Kasper from the University of Michigan.

ЦитатаParker Solar Probe Instruments: WISPR

JHU Applied Physics Laboratory (https://www.youtube.com/channel/UCz4r-ikQdWEj1gG1aFJTy-g)

Опубликовано: 7 авг. 2018 г.

The Wide-Field Imager for Parker Solar Probe is the only imaging instrument aboard the spacecraft. WISPR looks at the large-scale structure of the corona and solar wind before the spacecraft flies through it. About the size of a shoebox, WISPR takes images fr om afar of structures like coronal mass ejections, or CMEs, jets and other ejecta from the Sun. These structures travel out from the Sun and eventually overtake the spacecraft, wh ere the spacecraft's other instruments take in-situ measurements. WISPR helps link what's happening in the large-scale coronal structure to the detailed physical measurements being captured directly in the near-Sun environment. WISPR was designed and developed by the Solar and Heliophysics Physics Branch at the Naval Research Laboratory in Washington, DC (principal investigator Russell Howard), which will also develop the observing program.

ЦитатаParker Solar Probe Thermal Protection System Installation

JHU Applied Physics Laboratory (https://www.youtube.com/channel/UCz4r-ikQdWEj1gG1aFJTy-g)

Опубликовано: 8 авг. 2018 г.

On June 27, 2018, Parker Solar Probe's heat shield - called the Thermal Protection System, or TPS - was installed on the spacecraft.

A mission sixty years in the making, Parker Solar Probe will make a historic journey to the Sun's corona, a region of the solar atmosphere. With the help of its revolutionary heat shield, now permanently attached to the spacecraft in preparation for its August 2018 launch, the spacecraft's orbit will carry it to within 4 million miles of the Sun's fiercely hot surface, where it will collect unprecedented data about the inner workings of the corona.

The eight-foot-diameter heat shield will safeguard everything within its umbra, the shadow it casts on the spacecraft. At Parker Solar Probe's closest approach to the Sun, temperatures on the heat shield will reach nearly 2,500 degrees Fahrenheit, but the spacecraft and its instruments will be kept at a relatively comfortable temperature of about 85 degrees Fahrenheit.

The heat shield is made of two panels of superheated carbon-carbon composite sandwiching a lightweight 4.5-inch-thick carbon foam core. The Sun-facing side of the heat shield is also sprayed with a specially formulated white coating to reflect as much of the Sun's energy away from the spacecraft as possible.

The heat shield itself weighs only about 160 pounds - here on Earth, the foam core is 97% air.

NASA's Parker Solar Probe is About to Lift Off

At 3:33 a.m. EDT on Aug. 11, while most of the U.S. is asleep, NASA's Kennedy Space Center in Florida will be abuzz with excitement. At that moment, NASA's Parker Solar Probe, the agency's historic mission to touch the Sun, will have its first opportunity to lift off.

Launching fr om Cape Canaveral Air Force Station in Florida, Parker Solar Probe will make its journey all the way to the Sun's atmosphere, or corona -- closer to the Sun than any spacecraft in history.

"Eight long years of hard work by countless engineers and scientists is finally paying off," said Adam Szabo, the mission scientist for Parker Solar Probe at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Nestled atop a United Launch Alliance Delta IV Heavy -- one of the world's most powerful rockets -- with a third stage added, Parker Solar Probe will blast off toward the Sun with a whopping 55 times more energy than is required to reach Mars. About the size of a small car, it weighs a mere 1,400 pounds.

"That's a relatively light spacecraft," said Andy Driesman, project manager for the mission at the Johns Hopkins Applied Physics Lab. "And it needs to be, because it takes an immense amount of energy to get to our final orbit around the Sun."

Zooming through space in a highly elliptical orbit, Parker Solar Probe will reach speeds up to 430,000 miles per hour -- fast enough to get fr om Philadelphia to Washington, D.C., in a second -- setting the record for the fastest spacecraft in history. During its nominal mission lifetime of just under 7 years, Parker Solar Probe will complete 24 orbits of the Sun -- reaching within 3.8 million miles of the Sun's surface at closest approach.

"We'll be going where no spacecraft has dared go before -- within the corona of a star," said project scientist Nicky Fox of APL. "With each orbit, we'll be seeing new regions of the Sun's atmosphere and learning things about stellar mechanics that we've wanted to explore for decades."

But getting so close to the Sun requires slowing down -- for which Parker will use the gravity of our neighbor planet, Venus.

"Parker Solar Probe uses Venus to adjust its course and slow down in order to put the spacecraft on the best trajectory," said Driesman. "We will fly by Venus seven times throughout the mission. Each time we fly by we get closer and closer to the Sun."

In an orbit this close to the Sun, the real challenge is to keep the spacecraft fr om burning up.

"NASA was planning to send a mission to the solar corona for decades, however,
we did not have the technology that could protect a spacecraft and its instruments from the heat," said Szabo. "Recent advances in materials science gave us the material to fashion a heat shield in front of the spacecraft not only to withstand the extreme heat of the Sun, but to remain cool on the backside."

The heat shield is made of a 4.5-inch thick carbon composite foam material between two carbon fiber face sheets. While the Sun-facing side simmers at 2,500 degrees Fahrenheit, behind the shield the spacecraft will be a cozy 85 degrees Fahrenheit.

Parker Solar Probe is also the first NASA mission to be named after a living individual: Dr. Eugene Parker, famed solar physicist who in 1958 first predicted the existence of the solar wind, the stream of charged particles and magnetic fields that flow continuously from the Sun, bathing Earth. The spacecraft's path through the corona allows it to observe the acceleration of the very solar wind that Parker predicted, right as it makes a critical transition from slower than the speed of sound to faster than it.

The corona is also wh ere the solar material is heated to millions of degrees and wh ere the most extreme events on the Sun occur, such as solar flares and coronal mass ejections -- accelerating particles to a fraction of the speed of light. These explosions create space weather events that can pummel Earth with high energy particles, endangering astronauts, interfering with GPS and communications satellites and, at their worst, disrupting our power grid.

This will be the first time that solar scientists can see the objects of their study up close and personal.

"All of our data on the corona so far have been remote," said Nicholeen Viall, solar physicist at Goddard. "We have been very creative to get as much as we can out of our data, but there is nothing like actually sticking a probe in the corona to see what's happening there."

And scientists aren't the only ones along for the adventure -- the spacecraft holds a microchip carrying the names of more than 1.1 million participants who signed up to send their name to the Sun (https://www.nasa.gov/feature/goddard/2018/more-than-11-million-names-installed-on-nasa-s-parker-solar-probe). Sometime between Aug. 11 and 23, the close of the launch period, these names and 1,400 pounds of solar protection and science equipment will begin their journey to the center of our solar system.

Three months later, Parker Solar Probe will reach its first close approach of the Sun in November 2018, and will send the data back in December.

"For scientists like myself, the reward of the long, hard work will be the unique set of measurements returned by Parker," said Szabo. "The solar corona is one of the last places in the solar system wh ere no spacecraft has visited before. It gives me the sense of excitement of an explorer."

Stay tuned -- Parker is about to take flight.

ЦитатаParker Solar Probe: Building the Thermal Protection System

JHU Applied Physics Laboratory (https://www.youtube.com/channel/UCz4r-ikQdWEj1gG1aFJTy-g)

Опубликовано: 9 авг. 2018 г.

The Thermal Protection System, or TPS, is an essential technology that enables Parker Solar Probe to get so close to the Sun. The TPS is a composite structure made of top and bottom carbon fiber facesheets with 4.5 inches of carbon-carbon foam between them. Together, they form the 8-foot diameter heat shield on the top of the spacecraft.

The outer Sun facing facesheet is sprayed with a special bright white plasma optical coating.

The TPS is light - only 160 pounds - yet very effective at protecting the spacecraft and scientific instruments from the Sun.

During closes approach the Sun-facing side of the TPS will reach temperatures of about 2,500°F, while the spacecraft and majority of the instruments will only experience temperatures around 85°F.

Ready for a journey into the sun's enigmatic, scorching corona, NASA's Parker Solar Probe has been encapsulated inside the nose cone of its Delta 4-Heavy rocket for liftoff Saturday.

These photos show the solar-powered probe's enclosure inside the Delta 4 fairing at the Astrotech payload processing facility in Titusville, Florida, last month. Ground crews transported the spacecraft, inside the fairing, to Cape Canaveral's Complex 37B launch pad July 31 for hoisting atop the already-assembled United Launch Alliance Delta 4-Heavy rocket.

Parker Solar Probe is set for launch at 3:33 a.m. EDT (0733 GMT) Saturday, kicking off a more than seven-year voyage that will take the spacecraft closer to the sun than any previous mission. Built at the Johns Hopkins University Applied Physics Laboratory, the $1.5 billion NASA-funded mission will get an extra boost fr om a solid-fueled Star 48BV third stage motor, giving the spacecraft enough speed to escape Earth's gravity.

The Star 48 upper stage motor is seen in these images attached to the bottom of Parker Solar Probe, as the combined stack was surrounded by the Delta 4's two-section payload shroud.

The probe will head for a flyby with Venus on Oct. 2, using the planet's gravity to slingshot closer to the sun for its first close approach to our star in November.

Scientists want to learn how the solar wind is generated in the sun's corona, and Parker Solar Probe carries sensors and a camera to investigate the unexplored region, wh ere temperatures soar to millions of degrees.

ЦитатаParker Solar Probe cleared for Saturday launch to 'touch the sun'

NASA managers Thursday cleared the $1.5 billion Parker Solar Probe for launch early Saturday on a daring mission to "touch the sun," repeatedly flying through its outer atmosphere to find out why the blazing corona is millions of degrees hotter than our star's visible surface.

The spacecraft's instruments also will map the sun's powerful magnetic field, the torrent of electrically charged particles that are constantly blasted away into space in explosive outbursts and the mechanism that accelerates those particles to extreme velocities.

The goal is to understand and be better able to predict the behavior of the solar wind that triggers auroral displays on Earth and occasionally wreaks havoc with power grids and satellites.
"This space weather has a direct influence, not always positive, on our technology in space, our spacecraft, it disrupts our communications, it creates a hazardous environment for astronauts and in the most extreme cases can actually affect our power grids here on the Earth," said Alex Young, associate director of NASA's Heliophysics Science Division.

"So it's of fundamental importance for us to be able to predict this space weather much like we predict weather here on Earth."

As for the sun's corona, the fiery halo of shimmering light seen during a total solar eclipse, scientists hope the Parker Solar Probe can answer one of their most fundamental questions.

"We're used to the idea that if I am standing next to a camp fire and I walk away fr om it, it gets cooler," Young said. "But this is not what happens on the sun. As we go fr om the surface of the sun, which is 10,000 degrees, and move up into the corona, we find ourselves quickly at millions of degrees.

"So this is a fundamental question that drives not only how this star works, our sun, but actually all the stars in the universe. And so, these are sort of the three fundamental questions we want to address: the speed of the solar wind, this eruptive phenomena, solar storms, and how is the corona heated?"

Nicola Fox, the Parker project scientist at Johns Hopkins University's Applied Physics Laboratory, described the solar probe as "the coolest hottest mission under the sun."

"Until you actually go there and touch the sun, you really can't answer these questions," she said. "Why is the corona hotter than the surface of the sun? That defies the laws of nature. It's like water flowing uphill, it shouldn't happen. Why in this region does the solar atmosphere suddenly get so energized that it escapes from the hold of the sun and bathes all of the planets? We have not been able to answer these questions."

But the Parker Solar Probe was built to do just that.

Perched atop a heavy-lift United Launch Alliance Delta 4 rocket, Parker will blast off from pad 37 at the Cape Canaveral Air Force Station at 3:33 a.m. EDT (GMT-4) Saturday. Forecasters are predicting a 70 percent chance of acceptable weather.

The powerful Delta 4 Heavy, ULA's most powerful launcher, will be making only its 10th flight since 2004. It is equipped with a Northrup Grumman solid-fuel upper stage that will act to drop the Parker probe out of Earth's 18-mile-per-second orbit around the sun, allowing it to fall inward for the first of seven gravity assist flybys of Venus over a planned seven-year mission.

"It is a beast of a rocket," Fox said of the Delta 4. "We need to go so fast because we have to lose the influence of the Earth."

The Venus flybys will help shape Parker's trajectory, eventually putting the spacecraft into an elliptical orbit with a low point of just 3.8 million miles from the sun's visible surface and a high point around the orbit of Venus.

To put that in perspective, if the Earth and sun were at opposite ends of a football field, the Parker probe would be on the four-yard line nearest the sun during close approach.

Along with being the first spacecraft to fly that close to a star, Parker also will be the fastest, streaking through the outer corona at some 430,000 mph -- fast enough to fly from Washington, DC, to Tokyo in less than one minute.

Those extremes will not be seen until the later orbits, but Parker will be collecting data during all of its trips around the sun, starting with its first close encounter three months after launch.

"In our very first flyby (of the sun), we get a little more than 15 million miles away from the sun's surface," Fox said. "We're still three times closer than anything has been before. ... The spacecraft is staying over the same area of the sun for many, many days, allowing us to do some really incredible science on our very first flyby."

While the corona blazes at millions of degrees, it is a tenuous environment and the heat transferred to the spacecraft will be much less. Even so, Parker's four-inch-thick 160-pound carbon composite heat shield will be subjected to some 2,500 degrees Fahrenheit during the closest approaches, hotter than flowing lava.

But on the back side of that heat shield, wh ere Parker's four instruments, its flight computer and other critical systems are located, temperatures will be maintained at a relatively cool 85 degrees. Its water-cooled solar panels will be retracted behind the heat shield during close approach with just the tips exposed to the blazing light -- and heat -- of the sun.

"You can put your hand inside your oven and you won't get burned unless you actually touch a surface," said Fox. "And it really is the same. The corona is a very tenuous plasma.

"If you think about the amount of particles that actually are striking the heat shield and depositing that heat in, the whole thing gets heated up to 2,500 degrees Fahrenheit. Again, I would just say don't touch the oven surface, don't touch the three-million-degree plasma!"

Appropriately enough, the spacecraft is named for Eugene Parker, the University of Chicago scientist who first theorized the existence of the solar wind in 1958. Now 91, Parker, the first living scientist to have a spacecraft named in his honor, flew to the Florida Space Coast to witness his first rocket launch.

"Since this is a mission into unknown territory, we have to be prepared for some surprises, things we never thought of or things we thought of but were not correct," he said in a recent briefing. "The heating, particularly during stormy times when the sun has a lot of flares and activity, that's wh ere one really doesn't know what we're going to find."

The Parker Solar Probe is equipped with four instruments. The FIELDS instrument will map out the sun's electric and magnetic fields, measuring waves and turbulence in the star's atmosphere to help scientists understand how magnetic field lines can explosively snap apart and re-align.

The Wide-Field Imager for Parker Solar Probe, or WISPR, will photograph the large scale structure of the corona before the spacecraft flies into it, studying coronal mass ejections, jets and other phenomena.

The Solar Wind Electrons Alphas and Protons Investigation, or SWEAP, will use two instruments to characterize the particles making up the solar wind, measuring their velocity, density and temperature.

Finally, the Integrated Science Investigation of the Sun, or ISOIS, relies on two instruments to measure particle energies, shedding light on their origin and how they were accelerated.

"The science is ground breaking, it's compelling, it's confused scientists and puzzled us for decades and decades and decades," Fox said. "We're now going to fly this mission."

ЦитатаLive coverage: Heavy-lifting Delta 4 rocket set for launch with Parker Solar Probe
August 10, 2018 (https://spaceflightnow.com/2018/08/) | Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

Launch crews are syncing their schedules for Saturday's early morning blastoff of NASA's Parker Solar Probe fr om Cape Canaveral.

Liftoff is set for the opening of a 65-minute window at 3:33 a.m. EDT (0733 GMT) aboard a United Launch Alliance Delta 4-Heavy rocket.
Parker Solar Probe will fly closer to the sun than any mission before, reaching a point as close as 3.8 million miles from our star in 2024 after a series of gravitational assist flybys of Venus.

With the help of a Northrop Grumman Star 48 upper stage motor, Parker Solar Probe will depart Earth with blistering speed to reach Venus for the mission's first planetary encounter Oct. 2. The spacecraft, built by the Johns Hopkins University Applied Physics Laboratory, will reach its first perihelion at a distance of roughly 15 million miles from the sun Nov. 5.

The will break a record set by the U.S.-German Helios 2 mission, which passed as close as 27 million miles (43.4 million kilometers) from the sun in April 1976.

Named for Eugene Parker, who correctly predicted the existence of the solar wind in 1958, Parker Solar Probe will fly through the corona, a super-heated envelope of plasma surrounding the sun wh ere temperatures soar to millions of degrees. The temperature at the surface of the sun is hundreds of times cooler, but still a blistering 10,000 degrees Fahrenheit (6,000 degrees Celsius).

The corona is thought by scientists to be the origin of the solar wind, a supersonic stream of charged particles flowing away from the sun in every direction, influencing the entire solar system and driving space weather.

"How is the solar wind accelerated up to millions of mph very quickly in the solar corona? The work that Dr. Parker has laid out is the foundational work for understanding this process, and this is one of the primary goals of the Parker Solar Probe," said Alex Young, associate director for science in the heliophysics division at NASA's Goddard Space Flight Center in Maryland.

The launch Saturday is timed to put Parker Solar Probe on the correct course to kick off its planned seven-year mission. The spacecraft has until Aug. 23 to leave Earth, or else wait for the next interplanetary launch period in May 2019.
The joint NASA/ULA launch team planned to adjust their schedules late this week for the Delta 4 countdown, which is scheduled to begin at 6:33 p.m. EDT (2233 GMT).

Final launch preps for the Parker Solar Probe spacecraft are scheduled to get underway Friday morning, and ULA's ground crew at Cape Canaveral's Complex 37B launch pad will ready the facility's mobile gantry for retraction into position for liftoff.

The 330-foot-tall Mobile Service Tower should be rolled away from the Delta 4-Heavy rocket on rail tracks around 6:18 p.m. EDT (2218 GMT) to reveal the launcher, which is comprised of three hydrogen-fueled first stage cores, a cryogenic second stage, and the solid-fueled Star 48 third stage motor.

The Delta 4-Heavy rocket stands approximately 233 feet tall, and Saturday's mission will mark the 10th flight of ULA's most powerful launcher.

ULA workers will clear the launch pad later Friday evening ahead of the start of fueling of the Delta 4-Heavy with around 465,000 gallons of super-cold liquid hydrogen and liquid oxygen propellants.

The launch team will arrive at their consoles at the Delta Operations Center shortly before 11 p.m. EDT (0300 GMT). Controllers will oversee loading of cryogenic propellants into the Delta 4-Heavy beginning around 11:30 p.m. EDT (0330 GMT).
Forecasters from the U.S. Air Force's 45th Weather Squadron predict a 70 percent probability of favorable weather. Here's the forecast summary:
ЦитатаThe Bermuda high pressure ridge is south, and the low-level flow over the Space Coast is from the southwest. The southwest flow will converge with the sea breeze this afternoon and cause mid-afternoon thunderstorms. This pattern will continue for the next several days. Friday, afternoon thunderstorms will be in the area near the time of the Mobile Service Tower roll operations, but weather will improve shortly thereafter. Thunderstorms will likely continue over the Gulf Stream ~30nm offshore during the overnight hours, and northeast upper-level winds could cause anvils from offshore thunderstorms to migrate toward the Space Coast. The primary concerns for launch are cumulus clouds and anvil clouds.
At launch time, the forecast calls for offshore thunderstorms, scattered clouds at 3,000 feet, broken clouds at 25,000 feet, winds from the west at 8 knots, and a temperature of 79 degrees Fahrenheit.

Цитата08/11/2018 02:12 Stephen Clark

The Mobile Service Tower at Cape Canaveral's Complex 37B launch pad is in motion, revealing the 233-foot-tall Delta 4-Heavy rocket for liftoff at 3:33 a.m. EDT (0733 GMT) with NASA's Parker Solar Probe.

The mobile gantry -- which weighs in at around 9 million pounds -- is moving on rail tracks to a park position around 300 feet northeast of the launch mount at Complex 37B.

The structure provided weather protection for the Delta 4-Heavy, and access to the launch vehicle for engineers and technicians, since the rocket's rollout and erection at the launch pad in April.

The tower stands around 330 feet tall, and measures 90 feet wide and 40 feet deep. It was built before the first Delta 4 launch in 2002.
The next step in this evening's countdown will be final closeouts at the launch pad, before evacuation of workers to a safe fallback position ahead of the start of cryogenic tanking. Launch managers from United Launch Alliance and NASA will receive a weather briefing at around 10 p.m. EDT (0200 GMT), and fueling of the Delta 4-Heavy with liquid hydrogen and liquid oxygen should begin soon after 11 p.m. EDT (0300 GMT).

There remains a 70 percent probability of acceptable weather during Saturday's 65-minute launch window.

The countdown has resumed following a built-in hold at T-minus 4 hours, 15 minutes, and the Delta 4 launch team is on station inside the Delta Operations Center a couple of miles from the Complex 37B launch pad.

ULA's launch team is now targeting liftoff at 3:53 a.m. EDT (0753 GMT) after using an extra 20 minutes in the built-in hold to resolve an unspecified technical issue.

Coming up in the next hour, the launch team will kick off steps to fill the Delta 4-Heavy's three first stage Common Booster Cores and second stage with a mixture of liquid hydrogen and liquid oxygen propellants.

... Stage 2 will fire again to reach escape velocity, and end up in an solar orbit that I estimate around 0.37 x 1.0 AU. Stage 3 will then fire to add even more speed, and it and the PSP will end up in a 0.21 x 1.0 AU orbit.

Super-cold liquid hydrogen and liquid oxygen propellants are now being pumped aboard the Delta 4-Heavy rocket at Cape Canaveral.

About 465,000 gallons of cryogenic propellants will be loaded into the launcher during the countdown, starting with 330,000 gallons of liquid hydrogen for the Delta 4-Heavy's three Common Booster Cores.

Another 120,000 gallons of liquid oxygen is also flowing into the Common Booster Cores. An Aerojet Rocketdyne RS-68A main engine at the base of each booster will consume the hydrogen/oxygen propellant mixture in flight.

The liquid hydrogen is stored at minus 423 degrees Fahrenheit, while the liquid oxygen is chilled to minus 298 degrees Fahrenheit. Both fluids will be replenished in the rocket's tanks throughout the countdown to replace the cryogenics as they boil off in the warm ambient atmosphere on Florida's Space Coast.

This launch uses a special three-stage configuration of the United Launch Alliance Delta IV Heavy rocket to launch Parker Solar Probe from the Earth.
This configuration of the Delta IV is created by taking three hydrogen-fueled common booster cores, each with an Aerojet Rocketdyne RS-68A main engine, and strapping them together to provide over two million pounds of Earth-shaking thrust at liftoff. The Delta Cryogenic Second Stage, powered by an Aerojet Rocketdyne RL10B-2 engine, puts the vehicle into a preliminary orbit, then fires a second time to achieve an Earth-escape trajectory. A Star 48BV third stage, built by Northrop Grumman, provides a significant kick of additional velocity for the Parker Solar Probe on its journey into the inner solar system.

The Delta IV Heavy launches on the combined power of three RS-68A engines, burning liquid hydrogen and liquid oxygen to produce 702,000 pounds of thrust each. The port and starboard boosters are more than 150 feet tall, and the center core with the interstage attached is over 175 feet in length. They measure 16.7 feet in diameter.

The Delta Cryogenic Second Stage also burns liquid hydrogen and liquid oxygen to produce 24,750 pounds of thrust from the RL10B-2 engine. The powerplant features a deployable carbon-carbon nozzle that is 7 feet in diameter.

The Star 48BV motor serves as the Delta IV Heavy's third stage. It is the latest evolution in the long line of Star 48 stages and incorporates a vectorable nozzle for added maneuverability.

The Delta IV Heavy has successfully flown into space 9 times before, deploying vital national security payloads for the U.S. Air Force and National Reconnaissance Office and sending NASA's Orion capsule on its first flight test.

These photos taken Friday evening show the mobile gantry being wheeled away fr om a United Launch Alliance Delta 4-Heavy rocket at Cape Canaveral, hours before its scheduled blastoff with NASA's Parker Solar Probe.

The rollback of the Mobile Service Tower at Cape Canaveral's Complex 37B launch pad occurred shortly after 7 p.m. EDT (2300 GMT) Friday as launch crews prepped the 233-foot-tall (71-meter) Delta 4-Heavy rocket for liftoff.
Launch was set for a 65-minute window opening at 3:33 a.m. EDT (0733 GMT) Saturday.

NASA's Parker Solar Probe will depart Earth on a $1.5 billion mission to investigate the sun's corona, our star's super-heated atmosphere wh ere the solar wind is generated, extending the sun's influence throughout the solar system. ULA's biggest rocket, the Delta 4-Heavy, is required to send Parker Solar Probe on its speedy journey into the inner solar system, eventually reaching an orbit taking just 3.83 million miles (6.16 million kilometers) in 2024.

Fitted with sensors and a white light camera, the 1,424-pound (646-kilogram) spacecraft needs an extra boost to give it more velocity than even the Delta 4-Heavy can provide. A solid-fueled Star 48BV rocket motor, provided by Northrop Grumman Innovation Systems, will give the solar probe roughly two-thirds of the speed it requires to leave Earth.

Multiple flybys of Venus will use gravity to spiral Parker Solar Probe ever-closer to the sun over the course of 24 orbits, eventually placing the spacecraft well inside the orbit of Mercury.

An automatic alarm in the final two minutes of the Delta 4-Heavy rocket's countdown early Saturday forced officials to delay blastoff with NASA's Parker Solar Probe by 24 hours.

NASA and United Launch Alliance -- the builder of the Delta 4-Heavy -- rescheduled the launch of the $1.5 billion solar probe for 3:31 a.m. EDT (0731 GMT) Sunday, at the opening of a 65-minute window.

Officials hope to dodge anvil clouds that could blow over the Cape Canaveral spaceport fr om offshore thunderstorms during Sunday's early morning launch window. The official launch weather forecast fr om the U.S. Air Force's 45th Weather Squadron predicts a 60 percent probability of acceptable conditions for launch Sunday.

Scattered thunderstorms are forecast to move through Central Florida from the west Saturday afternoon, but the weather should improve in the evening hours.
"Storms should move offshore and dissipate before the Mobile Service Tower roll operations, and weather will improve in the overnight hours," the Air Force weather team wrote in a launch forecast issued early Saturday. "Closer to the launch window, thunderstorms will likely continue over the Gulf Stream offshore, and east upper-level winds could cause anvils from offshore thunderstorms to migrate toward the Space Coast."

NASA and ULA officials intended to launch Parker Solar Probe on Saturday, but a series of unspecified technical issues -- capped by an alarm at T-minus 1 minute, 55 seconds -- kept the 233-foot-tall (71-meter) Delta 4-Heavy rocket on the ground.

A problem early in the countdown caused a 20-minute delay from Saturday's original launch time of 3:33 a.m. EDT (0733 GMT), then a data stream issue further delayed the Delta 4-Heavy's takeoff time to 4:28 a.m. EDT (0828 GMT).

The countdown picked up from a hold at T-minus 4 minutes, but a member of the launch team announced a gaseous helium regulator alarm at T-minus 1 minute, 55 seconds. There was not enough time remaining in the launch window Saturday to resolve the alarm, so launch managers declared a scrub for the day.

In a brief statement, ULA said the launch was scrubbed "due to a violation of a launch lim it, resulting in a hold."

No other information about the gaseous helium system alarm, or the other technical concerns during the countdown, were released by NASA or ULA.

Parker Solar Probe has until Aug. 23 to depart Earth and kick off a seven-year mission to fly through the sun's atmosphere, making 24 orbits through the inner solar system and using the gravity of Venus to nudge ever-closer to our star. The compact, automated space probe will reach an orbit passing as close as 3.83 million miles (6.16 million kilometers) from the sun in 2024.

The spacecraft carries instrumentation to measure the environment in the sun's corona, the super-heated halo of plasma extending out from the solar surface, wh ere temperatures reach millions of degrees. Scientists designed the mission to probe the corona for the first time, and study how the solar wind is generated and accelerated into the solar system.

Parker Solar Probe will set records as the closest spacecraft to fly to the sun, and it will become the fastest human-made object in history, reaching a speed of roughly 430,000 mph -- 120 miles per second or nearly 700,000 kilometers per hour -- during its final perihelion passages in the mid-2020s.

If the mission has not launched by Aug. 23, the liftoff will be delayed to May 2019, the next opportunity to take advantage of an alignment in the orbits of Earth and Venus to make the journey to the sun possible.

This is Delta Launch Control from the Delta Operations Center at Cape Canaveral Air Force Station in Florida as we begin a second launch attempt for the Delta IV Heavy rocket carrying NASA's Parker Solar Probe.

The Air Force weather officer on duty at the 45th Weather Squadron just provided a briefing to senior management on conditions expected during retraction of the launch pad's mobile service gantry and the forecast for the rest of the evening.

Overall, weather looks favorable for rolling the tower to its launch position. Typical summertime thunderstorms around Central Florida are being monitored, but skies at the Cape are clear right now. One final weather check will be made before the actual move begins.

The tower was returned to its position shielding the rocket following this morning's scrub and de-fueling operations. Now, we're getting ready to retract the tower for tonight's countdown.

This is Delta Launch Control at T-minus 8 hours and counting.

The launch team has initiated a second countdown to fly the United Launch Alliance's Delta IV Heavy rocket and send NASA's Parker Solar Probe on its voyage to become the first spacecraft to "touch" the sun.

The application of power to the avionics aboard the Delta IV Heavy rocket is beginning at the start of today's countdown. The equipment is being powered up to start launch day testing and final preparations for fueling operations.

Activities are on schedule for liftoff at 3:31 a.m. EDT (0731 UTC). The day's launch window will remain open through 4:36 a.m. (0836 UTC), a duration of 65 minutes.

The countdown features two pre-planned, built-in holds, each lasting 30 minutes, scheduled in the count. One pause is reserved prior to fueling at T-minus 4 hours, 15 minutes, the other occurs prior to the Terminal Count at T-minus 4 minutes.

ЦитатаDelta 4-Heavy launch timeline with Parker Solar Probe
August 11, 2018 (https://spaceflightnow.com/2018/08/) | Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

A United Launch Alliance Delta 4-Heavy rocket, crowned by a solid-fueled upper stage kick motor, will send NASA's Parker Solar Probe on a speedy voyage through the inner solar system following liftoff from Cape Canaveral.

The 233-foot-tall (71-meter) launcher is set for liftoff from Cape Canaveral's Complex 37B launch pad powered by three Aerojet Rocketdyne RS-68A main engines.

The Delta 4-Heavy has flown nine times before, and is made up of three modified Delta 4 first stage cores bolted together. The all-cryogenic launcher burns a mixture of liquid hydrogen and liquid oxygen.

The $1.5 billion Parker Solar Probe mission will become the first spacecraft to travel inside the sun's corona, a scorching region of plasma extending a few million miles away from our star's surface. The mission's objectives include helping scientists unravel how the solar wind is heated and accelerated into the solar system, impacting the planets, including our own.

The timeline below is a rough approximation of the timing of the major launch events for the Delta 4-Heavy launch with Parker Solar Probe. The exact timing changes day-to-day based on the launch date in the mission's interplanetary window, which extends to Aug. 23.
Date source: ULA

T+00:00:00 -- Liftoff

(https://mk0spaceflightnoa02a.kinstacdn.com/wp-content/uploads/2018/08/d4h_liftoff-678x382.jpg)
The United Launch Alliance Delta 4-Heavy rocket takes off powered by three Aerojet Rocketdyne RS-68A main engines. The hydrogen-burning powerplants ignite in a staggered fashion, with the starboard Common Booster Core set to ignite at T-minus 7 seconds, followed by the port and center boosters at T-minus 5 seconds.

T+00:03:57.6 -- Port and Starboard Booster Jettison

(https://mk0spaceflightnoa02a.kinstacdn.com/wp-content/uploads/2018/08/d4h_boosterjettison-678x382.jpg)
After consuming their liquid hydrogen and liquid oxygen propellant mixture, the Delta 4-Heavy's port and starboard Common Booster Cores shut down their RS-68A main engines and jettison from the center core, which throttles up from a partial thrust setting to a full thrust mode after booster separation.

T+00:05:35.9 -- Booster Engine Cutoff

(https://mk0spaceflightnoa02a.kinstacdn.com/wp-content/uploads/2018/08/d4h_beco-678x382.jpg)
The Delta 4's center RS-68A main engine shuts down after burning its supply of super-cold liquid hydrogen and liquid oxygen.

T+00:05:42.4 -- First Stage Separation

The Delta 4's second stage Aerojet Rocketdyne RL10B-2 engine ignites and powers up to 24,750 pounds of thrust in the first of its two firings on the Parker Solar Probe mission.

T+00:06:05.4 -- Payload Fairing Jettison

(https://mk0spaceflightnoa02a.kinstacdn.com/wp-content/uploads/2018/08/d4h_fairingjettison-678x381.jpg)
The Delta 4's composite bisector fairing jettisons from the rocket once the launcher reaches a safe altitude above the dense lower layers of Earth's atmosphere.

T+00:10:37.1 -- First Main Engine Cutoff

(https://mk0spaceflightnoa02a.kinstacdn.com/wp-content/uploads/2018/08/d4h_meco1-678x383.jpg)
The second stage's RL10B-2 engine shuts down after placing Parker Solar Probe in a preliminary parking orbit, beginning a 12-minute coast before the engine reignites.

T+00:22:25.4 -- Second Main Engine Start

(https://mk0spaceflightnoa02a.kinstacdn.com/wp-content/uploads/2018/08/d4h_mes2-678x384.jpg)
The RL10B-2 second stage engine ignites again to send Parker Solar Probe on a trajectory to escape Earth's gravitational bond.

T+00:36:38.9 -- Second Main Engine Cutoff

(https://mk0spaceflightnoa02a.kinstacdn.com/wp-content/uploads/2018/08/d4h_meco2-678x379.jpg)
After burn lasting more than 14 minutes, the RL10B-2 second stage engine shuts down to end its second firing on the Parker Solar Probe mission.

T+00:37:09.0 -- Second Stage Separation

(https://mk0spaceflightnoa02a.kinstacdn.com/wp-content/uploads/2018/08/d4h_3rdstagesep-678x382.jpg)

We are entering the final 60 minutes of our countdown to launch of the Delta IV Heavy rocket and NASA's Parker Solar Probe, a mission decades in the making to fly through the sun's outer atmosphere to obtain in-situ measurements of how the corona is heated and how the solar wind is accelerated.

The launch team has begun to power up the Northrop Grumman Star 48BV third stage. The stage provides a significant kick of additional velocity for the Parker Solar Probe on its journey into the inner solar system.

No significant issues are being addressed by the launch team, the current weather conditions are favorable and all activities are progressing smoothly for a liftoff at 3:31 a.m. EDT (0731 UTC).

Это должен быть великий аппарат! Специально попробую написать что-то по поводу приоритетов в исследовании Солнца.

The key thing to understand about this launch is that it was in the OPPOSITE direction to Earth's motion. It was basically a retro burn, like a spacecraft in Earth orbit does to reenter and land.

In the launch control at Cape Canaveral Air Force Station, NASA and contractor managers and engineers monitor progress in the countdown to launch NASA's Parker Solar Probe. The poll is designed to verify that all is ready for liftoff. The spacecraft will perform the closest-ever observations of a star when it travels through the Sun's atmosphere, called the corona. Liftoff is scheduled to lift off at 3:31 a.m. EDT on Aug. 12, 2018.

Cape Canaveral Air Force Station, Fla., (Aug. 11, 2018) - A United Launch Alliance (ULA) Delta IV Heavy rocket carrying NASA's Parker Solar Probe spacecraft lifted off from Space Launch Complex-37 on Aug. 12 at 3:31 a.m. EDT. NASA selected ULA's Delta IV Heavy for its unique ability to deliver the necessary energy to begin the Parker Solar Probe's journey to the sun.

The Delta IV Heavy is the nation's proven heavy lift launch vehicle, delivering high-priority missions for NASA, the U.S. Air Force and the National Reconnaissance Office. With its advanced cryogenic upper stage, Delta IV Heavy can deliver more than 14,000 pounds directly to geosynchronous orbit, as well as a wide variety of complex interplanetary trajectories.

"The unique requirements of this mission made the Delta IV Heavy the perfect launch vehicle to deliver Parker Solar Probe into orbit with the highest precision," said Gary Wentz, ULA vice president of Government and Commercial Programs. "Congratulations to our team and mission partners, we are proud to launch this exceptional spacecraft that will provide invaluable scientific information benefiting all of humankind."

This mission was launched aboard a Delta IV Heavy, which is comprised of three common core boosters each powered by an Aerojet Rocketdyne (AR) RS-68A liquid hydrogen/liquid oxygen engines producing a combined total of more than 2.1 million pounds of thrust. The second stage was powered by an AR RL10B-2 liquid hydrogen/liquid oxygen engine. Due to the extremely high energy required for this mission, the Delta IV Heavy's capability was enhanced by a powerful third stage provided by Northrop Grumman.

This was the 37th launch of the Delta IV rocket, and the 10th in the Heavy configuration. It also marks ULA's sixth launch in 2018 and the 129th successful launch since the company was formed in December 2006.
ULA's next launch is the ICESat-2 mission for NASA on what will be the final Delta II mission. The launch is scheduled for Sept.15 at Space Launch Complex-2 at Vandenberg Air Force Base, California.

With more than a century of combined heritage, United Launch Alliance is the nation's most experienced and reliable launch service provider. ULA has successfully delivered more than 125 satellites to orbit that aid meteorologists in tracking severe weather, unlock the mysteries of our solar system, provide critical capabilities for troops in the field and enable personal device-based GPS navigation.

NASA, ULA Launch Parker Solar Probe on Historic Journey to Touch Sun

Hours before the rise of the very star it will study, NASA's Parker Solar Probe (http://nasa.gov/solarprobe) launched fr om Florida Sunday to begin its journey to the Sun, wh ere it will undertake a landmark mission. The spacecraft will transmit its first science observations in December, beginning a revolution in our understanding of the star that makes life on Earth possible.

The United Launch Alliance Delta IV Heavy rocket launches NASA's Parker Solar Probe to touch the Sun, Sunday, Aug. 12, 2018, from Launch Complex 37 at Cape Canaveral Air Force Station, Florida. Parker Solar Probe is humanity's first-ever mission into a part of the Sun's atmosphere called the corona. Here it will directly explore solar processes that are key to understanding and forecasting space weather events that can impact life on Earth.

Roughly the size of a small car, the spacecraft lifted off at 3:31 a.m. EDT on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex-37 at Cape Canaveral Air Force Station. At 5:33 a.m., the mission operations manager reported that the spacecraft was healthy and operating normally.

The mission's findings will help researchers improve their forecasts of space weather events, which have the potential to damage satellites and harm astronauts on orbit, disrupt radio communications and, at their most severe, overwhelm power grids.

"This mission truly marks humanity's first visit to a star that will have implications not just here on Earth, but how we better understand our universe," said Thomas Zurbuchen, associate administrator of NASA's Science Mission Directorate. "We've accomplished something that decades ago, lived solely in the realm of science fiction."

During the first week of its journey, the spacecraft will deploy its high-gain antenna and magnetometer boom (https://www.nasa.gov/image-feature/parker-solar-probe-magnetometer-boom-deployed). It also will perform the first of a two-part deployment of its electric field antennas. Instrument testing will begin in early September and last approximately four weeks, after which Parker Solar Probe can begin science operations.

"Today's launch was the culmination of six decades of scientific study and millions of hours of effort," said project manager Andy Driesman, of the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland. "Now, Parker Solar Probe is operating normally and on its way to begin a seven-year mission of extreme science."

Over the next two months, Parker Solar Probe will fly towards Venus, performing its first Venus gravity assist (https://solarsystem.nasa.gov/basics/primer/) in early October - a maneuver a bit like a handbrake turn - that whips the spacecraft around the planet, using Venus's gravity to trim the spacecraft's orbit tighter around the Sun. This first flyby will place Parker Solar Probe in position in early November to fly as close as 15 million miles from the Sun - within the blazing solar atmosphere, known as the corona - closer than anything made by humanity has ever gone before.

Throughout its seven-year mission, Parker Solar Probe will make six more Venus flybys and 24 total passes by the Sun, journeying steadily closer to the Sun until it makes its closest approach at 3.8 million miles. At this point, the probe will be moving at roughly 430,000 miles per hour, setting the record for the fastest-moving object made by humanity.

Parker Solar Probe will set its sights on the corona to solve long-standing, foundational mysteries of our Sun. What is the secret of the scorching corona (https://www.nasa.gov/feature/goddard/2018/nasa-s-parker-solar-probe-and-the-curious-case-of-the-hot-corona), which is more than 300 times hotter than the Sun's surface, thousands of miles below? What drives the supersonic solar wind (https://www.nasa.gov/feature/goddard/2018/parker-solar-probe-and-the-birth-of-the-solar-wind) - the constant stream of solar material that blows through the entire solar system? And finally, what accelerates solar energetic particles, which can reach speeds up to more than half the speed of light as they rocket away from the Sun?

Scientists have sought these answers for more than 60 years, but the investigation requires sending a probe right through the unrelenting heat of the corona. Today, this is finally possible with cutting-edge thermal engineering advances (https://www.nasa.gov/feature/goddard/2018/traveling-to-the-sun-why-won-t-parker-solar-probe-melt/) that can protect the mission on its daring journey.

"Exploring the Sun's corona with a spacecraft has been one of the hardest challenges for space exploration," said Nicola Fox, project scientist at APL. "We're finally going to be able to answer questions about the corona and solar wind raised by Gene Parker in 1958 - using a spacecraft that bears his name - and I can't wait to find out what discoveries we make. The science will be remarkable."

Parker Solar Probe carries four instrument suites designed to study magnetic fields, plasma and energetic particles, and capture images of the solar wind. The University of California, Berkeley, U.S. Naval Research Laboratory in Washington, University of Michigan in Ann Arbor, and Princeton University in New Jersey lead these investigations.

Parker Solar Probe is part of NASA's Living with a Star program to explore aspects of the Sun-Earth system that directly affect life and society. The Living with a Star program is managed by the agency's Goddard Space Flight Center in Greenbelt, Maryland, for NASA's Science Mission Directorate in Washington. APL designed and built, and operates the spacecraft.

NASA's Parker Solar Probe (https://www.nasa.gov/content/goddard/parker-solar-probe) is on its way for a rendezvous with the Sun. A United Launch Alliance Delta IV Heavy rocket, carrying the spacecraft, lifted off at 3:31 a.m. EDT, from Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida, its engines blazing golden in the clear night sky during ascent.

"It was a very quiet launch countdown, it went off like clockwork," said Omar Baez, NASA Launch Director. "Parker Solar Probe has been one of our most challenging missions to date. I'm very proud of the team that worked to make this happen. We at NASA and the Launch Services Program are thrilled to be part of this mission."

About four minutes into flight, a series of key events occurred. The Delta IV port and starboard booster engines shut down and separated, the main core booster engine cut off and then separated from the second stage. After second stage engine ignition, the payload fairing was jettisoned. After second stage main engine cutoff and separation, the Parker Solar Probe separated from the third stage, provided by Northrup Grumman. Shortly afterward, mission managers confirmed that the spacecraft's solar arrays successfully deployed and the spacecraft was operating on its own power.

During its mission to "touch" the Sun, Parker Solar Probe will use gravity assists from Venus seven times over nearly seven years to gradually bring its orbit closer to the Sun. It will fly directly through the Sun's atmosphere, as close as 3.8 million miles from its surface, closer to the surface than any spacecraft before it. The spacecraft will hurtle around the Sun at speeds up to 430,000 miles per hour. That's 15 times faster than a speeding bullet.

Parker Solar Probe will revolutionize our understanding of the Sun's corona. Facing brutal heat and radiation, the spacecraft will fly close enough to watch the solar wind speed up from subsonic to supersonic, and fly through the birthplace of the highest-energy solar particles. Parker Solar Probe and its instruments will be protected from the Sun's heat by a 4.5-inch-thick, carbon-carbon composite heat shield. The shield's front surface will be able to withstand temperatures outside the spacecraft up to 2,500 degree Fahrenheit. While the inside, or back surface of the shield will withstand temperatures up to 650 degrees Fahrenheit.

For more than 60 years, scientist have wondered how energy and heat move through the solar corona and what accelerates the solar wind as well as solar energetic particles. Now, with the help of cutting-edge thermal technology that can protect the mission on its dangerous journey, the spacecraft's four instrument suites will study magnetic fields, plasma and energetic particles, and image the solar wind.

In 2017, the mission was renamed for Eugene Parker, the S Chandrasekhar Distinguished Service Professor Emeritus, Department of Astronomy and Astrophysics at the University of Chicago. In the 1950s, Parker, a solar astrophysicist, proposed a number of concepts about how stars-including our Sun-give off energy. He called this cascade of energy the solar wind, and he described an entire complex system of plasmas, magnetic fields, and energetic particles that make up this phenomenon. Parker also theorized an explanation for the superheated solar atmosphere, the corona, which is-contrary to what was expected by physics laws-hotter than the surface of the Sun itself. This is the first NASA mission that has been named for a living individual.

Parker Solar Probe is part of NASA's Living With a Star program to explore aspects of the Sun-Earth system that directly affect life and society. The Living With a Star flight program is managed by the agency's Goddard Space Flight Center in Greenbelt, Maryland, for NASA's Science Mission Directorate in Washington. The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, manages the mission for NASA. APL designed and built the spacecraft and also will operate it.

Parker Solar Probe is the fourth mission for NASA's Launch Services Program (https://www.nasa.gov/centers/kennedy/launchingrockets/index.html) (LSP) this year. LSP is responsible for launch service acquisition, integration, analysis and launch management for each mission.

This concludes today's coverage of NASA's Parker Solar Probe countdown, launch and ascent into space for its mission to explore the Sun.

Конечно, наука - это прекрасно. Но поскольку многие не имеют здесь к ней отношения, все же интересно вернуться к теме семьи. Так как, Алексей, плохо жить одному, когда все тебе крутят у виска, да? Плохо. А почему? Потому что гадов никто не терпит. Даже не то, что не любит, их невозможно любить. Невозможно не только любить, но и ненавидеть равнодушных плоских бесцветных "граждан".

ВАШИНГТОН, 12 августа. /ТАСС/. Национальное управление США по аэронавтике и исследованию космического пространства (NASA) осуществило в воскресенье запуск автоматической станции Parker Solar Probe для изучения Солнца. Она отправилась в космическое путешествие с помощью тяжелой ракеты-носителя Delta IV, стартовавшей с космодрома на мысе Канаверал (штат Флорида).

Американские ученые рассчитывают, что зонд, оснащенный научными приборами, предоставит им новые данные о процессах в солнечной атмосфере, имеющих важное значение для жизни на Земле. В конце своей миссии, запланированной на восемь лет, он приблизится к единственной звезде Солнечной системы на расстояние около 6 млн километров - столь тесного знакомства с ней не было еще ни у одного из космических аппаратов. Проект оценивается в $1,5 млрд.
Особые условия

Станция размером с небольшой автомобиль построена по правительственному заказу специалистами Лаборатории прикладной физики Университета Джонса Гопкинса, расположенной в Лореле (штат Мэриленд). А ее запуск осуществлен по программе "Жизнь со звездой", которую разработал научный департамент NASA совместно с Центром космических полетов имени Годдарда в Гринбелте (штат Мэриленд).

На этом объекте, также входящим в структуру космического ведомства США, в течение двух месяцев аппарат проходил испытания в условиях перепада экстремальных температур. Сначала инженеры поместили его в вакуумную камеру высотой около 12 метров, чтобы проверить, как зонд и его "начинка" будут чувствовать себя при минус 180 градусов по Цельсию, а затем стали повышать температуру, наблюдая за поведением своего подопечного. Специалисты чередовали низкую и высокую температуру, имитируя условия полета станции в космическом пространстве.

Изучение Солнца

Планируется, что зонд выйдет на орбиту вокруг Солнца и уже в ноябре приблизится к нему на расстояние 6,4 млн километров. Это означает, что он будет находиться в пределах короны Солнца, то есть внешнего и самого жаркого слоя его атмосферы, где температура может превысить 500 тыс. градусов по Цельсию.

По замыслу ученых, в период по июнь 2025 года аппарат совершит 24 витка вокруг Солнца, разгоняясь до скорости 724 тыс. километров в час. На каждый такой виток у него будет уходить 88 дней.

Во время трех последних витков зонд пройдет на расстоянии 6,08 млн километров от Солнца. Это в семь раз ближе рекордной дистанции, которая отделяла солнечную поверхность от аппарата Helios 2 в ходе научной миссии в 1976 году. Средняя удаленность Земли от Солнца составляет 149,6 млн километров.

Новый зонд Parker полетит к Солнцу, чтобы лучше понять процессы, происходящие на границе короны и атмосферы нашей звезды. Инфографика ТАСС поможет представить, какое Солнце удивительное. 

На борту Parker Solar Probe находятся научные приборы, с помощью которых специалисты рассчитывают, в частности, осуществить измерения солнечной радиации. Наряду с этим зонд должен будет передать на Землю фотоснимки, которые станут первыми, сделанными в пределах солнечной короны. Оборудование станции защищено оболочкой из углепластика толщиной 11,43 сантиметров, позволяющей выдержать температуру почти до 1,4 тыс. градусов по Цельсию.

Координатор проекта Никола Фокс из Лаборатории прикладной физики Университета Джонса Гопкинса отметила, что замыслы отправки такой миссии к Солнцу удалось реализовать только после того, как появились новые композитные материалы, использованные в первую очередь при создании термостойкого щита. Кроме того, станция оснащена новыми панелями солнечных батарей. "Мы наконец прикоснемся к Солнцу", - сказала эксперт. По ее словам, зонд поможет ученым понять, "как работает Солнце".

В честь Юджина Паркера

NASA обещает, что миссия произведет чуть ли не революцию в представлении о процессах, протекающих на Солнце.

Претворение в жизнь намеченных планов позволит внести "фундаментальный вклад" в понимание причин "нагревания солнечной короны", а также возникновения солнечного ветра - потока ионизированных частиц из внешней оболочки Солнца, считают американские ученые. Они уверены, что данные, которые зонд передаст на Землю, помогут "ответить на критически важные вопросы гелиофизики" и будут использованы при подготовке пилотируемых полетов в дальний космос, в том числе для прогнозирования радиационной обстановки.

Зонд назван в честь американского астрофизика Юджина Паркера, которому минувшим летом исполнилось 90 лет. Несмотря на возраст, он до сих пор ведет научную деятельность в Университете Чикаго (штат Иллинойс). Паркер стал одним из первых в мире специалистов, занимающихся исследованиями солнечного ветра. С 1967 года он является членом Национальной академии наук США.

Running a day late, a United Launch Alliance heavy-lift Delta 4 rocket thundered away from Cape Canaveral early Sunday, boosting NASA's $1.5 billion Parker Solar Probe into space on a daring seven-year mission to "touch the sun" with repeated trips through the star's blazing outer atmosphere.

Passing within 3.8 million miles of the sun's visible surface -- well within the shimmering halo of the outer atmosphere, or corona -- the spacecraft's heat shield will endure 2,500-degree heating while whipping past the star at a record 430,000 mph, fast enough to fly from New York to Tokyo in less than a minute.

The goal is to help scientists figure out what makes the corona hotter than the sun's visible surface and what accelerates charged particles to enormous velocities, producing the solar wind that streams away from the corona in all directions.

And the mystery is profound. The visible surface of the sun has a temperature of about 10,000 degrees Fahrenheit. But just above it, in the corona, the temperature shoots up to several million degrees.

Even though it will repeatedly fly through the corona, Parker will not experience such extreme temperatures because the ionized gas making up the outer atmosphere is so tenuous. But the probe's heat shield will still get hotter than lava while its instruments study the hellish environment in unprecedented detail.

Scientists have two theories about what heats up the corona. It could be due to interactions between electrically charged particles and the sun's powerful magnetic field, or it could be the result of countless "nanoflares" governed by another mechanism. Or maybe, both.

"Until you actually go there and touch the sun, you really can't answer these questions," said Project Scientist Nicola Fox. "Why is the corona hotter than the surface of the sun? That defies the laws of nature. It's like water flowing uphill, it shouldn't happen.

"Why in this region does the solar atmosphere suddenly get so energized that it escapes from the (gravitational) hold of the sun and bathes all of the planets? We have not been able to answer these questions."

Learning more about the solar wind also will help scientists better predict the effects of solar storms and the impact of the solar wind on Earth's magnetic field, wreaking havoc with communications, power grids and navigation.

"This space weather has direct influence, not always positive, on our technology in space, our spacecraft, it disrupts our communications, it creates a hazardous environment for astronauts and in the most extreme cases can actually affect our power grids here on the Earth," said Alex Young, associate director of NASA's heliophysics program.

"So it's of fundamental importance for us to be able to predict this space weather much like we predict weather here on Earth."

To reach its target, the Delta 4 Heavy and a solid-propellant upper stage had to supply enough energy to counteract Earth's 18-mile-per-second orbital velocity around the sun, allowing the spacecraft to fall into the inner solar system.

Running 24 hours late because of a last-minute countdown glitch Saturday, the trek began at 3:31 a.m. EDT (GMT-4) Sunday when the 233-foot-tall Delta's three hydrogen-fueled Aerojet-Rocketdyne RS-68A main engines ignited with a rush of brilliant orange flame and quickly throttled up to 2.1 million pounds of thrust.

Looking on at launch was Eugene Parker, the University of Chicago astrophysicist who first theorized the existence of the solar wind in 1958. Now 91, Parker, the first living scientist to have a space probe named in his honor, flew to Cape Canaveral to witness his first rocket launch.

The Delta 4 Heavy did not disappoint.

"I really have to turn from biting my nails and getting it launched to thinking about all the interesting things, which I don't know yet, and which will be made clear, I assume, over the next five or six or seven years," Parker said in a NASA interview.

"It's a whole new phase, and it's going to be fascinating throughout. ... All I can say is wow, here we go. We're in for some learning over the next several years."

Trailing a plume of fiery exhaust visible for scores of miles around, the huge 1.6-million-pound rocket majestically climbed away from launch complex 37B at the Cape Canaveral Air Force Station, arcing away on an easterly trajectory over the Atlantic Ocean.

The rocket smoothly accelerated as it consumed propellant and lost weight, powering out of the thick lower atmosphere in spectacular fashion. The two side boosters shut down and fell away as expected a bit less than four minutes after liftoff.

The central core booster continued firing for another minute and a half before it, too, shut down and fell away from the fast-moving second stage. A few seconds after that, the upper stage's single hydrogen-fueled Aerojet Rocketdyne RL10B-2 engine ignited to continue the climb to space.

Finally, after two firings of the second-stage engine, the Parker Solar Probe and its Northrup Grumman solid-fuel upper stage were released from the Delta 4. The upper stage then ignited for a short burn, supplying more than half of the probe's final velocity.

Forty-three minutes after launch, the spacecraft jettisoned the spent upper stage and began flying on its own.

If all goes well, the Parker Solar Probe will swing by Venus in about six weeks for a gravitational encounter that will help the spacecraft slow down still more. Seven Venus flybys are planned over the seven-year mission to fine-tune the trajectory, setting up the close-in aim points.

The first pass by the sun, at a distance of about 15 million miles -- three times closer than any previous spacecraft -- is expected in November.

"So we're already in a region of very, very interesting coronal area," Fox said. "In fact, one of the key things about our early orbits is we're actually just at this sort of sweet spot ... over the same area of the sun for many, many days, allowing us to do some really incredible science on our very first flyby."

August 13, 2018 (https://spaceflightnow.com/2018/08/) | Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

Driven by three RS-68A main engines, a United Launch Alliance Delta 4-Heavy rocket lifted off early Sunday from Cape Canaveral carrying NASA's Parker Solar Probe on a historic mission to study the sun.

The heavy-duty rocket, standing 233 feet (71 meters) tall, climbed away from Cape Canaveral's Complex 37B launch pad at 3:31 a.m. EDT (0731 GMT) Sunday, a day after officials scrubbed launch attempt due to an alarm in the final two minutes of the countdown.

Three Aerojet Rocketdyne RS-68A main engines ignited in a staggered step-by-step fashion beginning at approximately T-minus 7 seconds, then throttled up to generate a combined 2.1 million pounds of thrust as the Delta 4-Heavy took off from Cape Canaveral.

NASA's Parker Solar Probe was bolted on top of the Delta 4-Heavy, the biggest rocket in the world, to begin a $1.5 billion mission to explore the sun's corona for the first time.

These photos show the Delta 4-Heavy's launch in the wee hours of Sunday morning.

Миссия «коснется Солнца», пролетев прямо через солнечную корону, столкнувшись с жестокой жарой и радиацией и предоставив беспрецедентно близкие наблюдения за звездой, у которой мы живем. Эти наблюдения будут касаться нерешенных научных вопросов, таких, например, как создаётся солнечная энергия Солнца и как ускоряется солнечный ветер. Это также принесет пользу людям на Земле, внося важный вклад в нашу способность прогнозировать основные события космической погоды, которые влияют на жизнь и технологии на Земле. Такая информация может пролить свет не только на то, как Солнце управляет космической средой в нашей собственной солнечной системе, но и обеспечит понимание других звезд во всей Вселенной. Чтобы раскрыть тайны короны, Parker Solar Probe будет иметь четыре инструмента, предназначенные для изучения магнитных полей, плазменных и энергетических частиц и изображения короны и солнечного ветра. Миссия будет использовать семь полётов Венеры в течение почти семи лет, чтобы постепенно уменьшать свою орбиту вокруг Солнца и выполнить в общей сложности 24 близких пролёта. Космический аппарат приблизится к Солнцу примерно на 3,8 миллиона миль (6,2 миллиона километров), гораздо ближе, чем раньше.
 Чтобы выполнить эти беспрецедентные исследования, космические аппараты и приборы защищены от солнечного тепла теплозащитным щитом толщиной до 4,5 дюйма (11,4 см), который выдерживает температуры почти 2500 градусов по Фаренгейту [1370 градусов Цельсия]». Обзор аппарата, его миссии и экспериментов, также приводятся некоторые основные факты по солнечной физике.

    ЦитатаChina's radio heliograph may cooperate with NASA's spacecraft in solar observation: scientist
    Source: Xinhua | 2018-08-14 22:19:42 | Editor: Yurou

    HOHHOT, Aug. 14 (Xinhua) -- A Chinese scientist says the country's solar radio heliograph is likely to cooperate with NASA's recently launched Parker Solar Probe to study the Sun.

    The Chinese Spectral Radioheliograph (CSRH), built at Ming'antu, a radio quiet region in north China's Inner Mongolia Autonomous Region, consists of 100 antennas with different frequency spectra covering an area of 10 square km. It can monitor solar activities on a wide imaging resolution spectrum.

    According to Yan Yihua, president of Division E Sun and Heliosphere, International Astronomical Union, the observation range of the CSRH and the Parker Solar Probe will overlap and it's possible that the two will cooperate in the future for specific scientific tasks.

    NASA's Parker Solar Probe, the fastest spacecraft in history, launched on Sunday, is on a mission to study the Sun at closer range than any other spacecraft.

    During its mission lifetime of seven years, the probe will complete 24 orbits of the Sun and fly within 6.1 million km of the Sun's surface at closest approach.

    "Data from both sides could corroborate and supplement each other," said Yan.

    ЦитатаКитайский радиогелиограф и американский солнечный зонд "Паркер" будут взаимодействовать в наблюдениях за Солнцем
    2018-08-14 14:49:56丨Russian.News.Cn

    Хух-Хото, 14 августа /Синьхуа/ -- После запуска в США солнечного зонда "Паркер" китайское степное "Небесное око" начало пристально следить за аппаратом, также планируется наладить взаимодействие с соответствующей стороной в области исследований Солнца, сообщил глава Отделения Солнца и гелиосферы Международного астрономического союза и заведующий Лабораторией по изучению солнечной активности Академии наук Китая Янь Ихуа.

    Зонд "Паркер" был запущен в США 12 августа в 15:31 по пекинскому времени. Он будет двигаться вокруг Солнца по эллиптической орбите и, выполнив семь гравитационных маневров около Венеры, будет постепенно приближаться к Солнцу, минимальное расстояние между зондом и звездой составит 6,1 млн км.

    Миссия зонда рассчитана на семь лет. За это время китайское степное "Небесное око" - Минъаньтуский спектральный радиогелиограф /MUSER/ во Внутренней Монголии - станет по своим возможностям самым мощным среди подобных устройств в мире. Это означает, что американский зонд и китайский радиогелиограф смогут еще больше взаимодействовать в изучении Солнца.

    В будущем, по мере введения в строй нового оборудования, область наблюдений китайского радиогелиографа за солнечной радиацией расширится с 700 тыс. км от поверхности Солнца до 7 млн км и пересечется с областью наблюдений, осуществляемых зондом "Паркер".

    Работа "Паркера" и китайского степного "Небесного ока" тесно переплетается, как по области наблюдений, так и по стоящим перед ними конкретными задачами, в частности, в изучении солнечного ветра и межпланетных мерцаний. Это позволит осуществлять одновременный анализ данных, полученных двумя сторонами, сверять их и дополнять, сказал Янь Ихуа.

    Early in the morning of Aug. 12, NASA launched Parker Solar Probe, humanity's first mission to the Sun. This spacecraft will fly closer to the Sun than any before it, in a daring journey facing brutal heat and radiation.

    Parker Solar Probe sets its sights on the Sun's scorching outer atmosphere, called the corona, in order to solve our star's greatest mysteries. It will revolutionize our understanding not only of the Sun, but also the space around us, and even the lives of stars beyond our solar system -- crucial information as we explore more of space.

    On Aug. 10, Scientists and mission experts gathered at NASA's Kennedy Space Center for a live sunset show -- one of the last times the Sun set on Parker Solar Probe before it launched -- to talk about what this landmark mission will teach us of the Sun.

    Just two days after launch on Aug. 11, 2018, from Cape Canaveral Air Force Station in Florida, NASA's Parker Solar Probe achieved several planned milestones toward full commissioning and operations, announced mission controllers at the Johns Hopkins Applied Physics Laboratory, or APL, in Laurel, Maryland.

    On Aug. 13, the high-gain antenna, which Parker Solar Probe uses to communicate high-rate science data to Earth, was released from locks which held it stable during launch. Controllers have also been monitoring the spacecraft as it autonomously uses its thrusters to remove (or "dump") momentum, which is part of the flight operations of the spacecraft. Managing momentum helps the spacecraft remain in a stable and optimal flight profile.

    There are four instrument suites on board Parker Solar Probe, which will each need to be powered and readied for science data collection. The FIELDS investigation, which consists of the most elements, went first. It was powered up on Aug. 13 for two activities. First was the opening of the clamps which held four of the five FIELDS antennas stowed during takeoff. These antennas will be deployed roughly 30 days after launch, and they will stick out from the corners of the spacecraft's heat shield -- called the Thermal Protection System -- and be exposed to the harsh solar environment. Second, the spacecraft's magnetometer boom was fully deployed. This boom contains three magnetometers and a fifth, smaller electric field antenna, all part of the FIELDS suite. Further instrument check-outs and deployments are scheduled in the coming days for the spacecraft.

    As of 12:00 p.m. EDT on Aug. 16, Parker Solar Probe was 2.9 million miles from Earth, traveling at 39,000 miles per hour, and heading toward its first Venus flyby scheduled for Oct. 3, 2018, at 4:44 a.m. EDT. The spacecraft will use Venus to slightly slow itself and adjust its trajectory for an optimal path toward first perihelion of the Sun on Nov. 5, 2018, at 10:27 p.m. EST (Nov. 6, 2018, at 03:27 UTC).

    "Parker Solar Probe is operating as designed, and we are progressing through our commissioning activities," said Project Manager Andy Driesman of APL. "The team -- which is monitoring the spacecraft 24 hours a day, seven days a week -- is observing nominal data from the systems as we bring them on-line and prepare Parker Solar Probe for its upcoming initial Venus gravity assist."

If space were a football field, with Earth at one end and the Sun at the other, Parker would be at the four-yard line, just steps away from the Sun! This journey will revolutionize our understanding of the Sun, its surface and solar winds.

    Supporting Parker on its journey to the Sun are our communications networks. Three networks, the Near Earth Network (https://t.umblr.com/redirect?z=https%3A%2F%2Fesc.gsfc.nasa.gov%2Fnen&t=MDQwNjRmOWE4M2RiOThmMmJiMjQ5NWMyNjdmNTYyM2QxNzVhNzJhMixQdG5mZk9nQQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F177093627469%2Fin-conversation-with-the-sun-parker-solar-probe&m=0), the Space Network (https://t.umblr.com/redirect?z=https%3A%2F%2Fesc.gsfc.nasa.gov%2Fsn&t=NzM0ZjQyMzQ5Y2I0MzBiZTAzYjUxYTVlNjYxNDUwYzM3NTEwYWYyMyxQdG5mZk9nQQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F177093627469%2Fin-conversation-with-the-sun-parker-solar-probe&m=0) and the Deep Space Network (https://t.umblr.com/redirect?z=https%3A%2F%2Fdeepspace.jpl.nasa.gov%2F&t=ZTYxNDEzOTJjMWRkOWRkYzZjNTkyOTIwZTVmZWE1MTVkNDExZjQ0NSxQdG5mZk9nQQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F177093627469%2Fin-conversation-with-the-sun-parker-solar-probe&m=0), provide our spacecraft with their communications, delivering their data to mission operations centers. Their services ensure that missions like Parker have communications support from launch through the mission.

    For Parker's launch (https://t.umblr.com/redirect?z=https%3A%2F%2Fwww.nasa.gov%2Fpress-release%2Fnasa-ula-launch-parker-solar-probe-on-historic-journey-to-touch-sun&t=ZWJlYTg5MmZkOTRjZTY2MzU0NzkzNDc5MDQ5MTA4NDU4ZGJlNjk0OSxQdG5mZk9nQQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F177093627469%2Fin-conversation-with-the-sun-parker-solar-probe&m=0) on Aug. 12, the Delta IV Heavy rocket that sent Parker skyward relied on the Space Network. A team at Goddard Space Flight Center's Networks Integration Center monitored the launch, ensuring that we maintained tracking and communications data between the rocket and the ground. This data is vital, allowing engineers to make certain that Parker stays on the right path towards its orbit around the Sun.

    The Space Network's constellation of Tracking and Data Relay Satellites (https://t.umblr.com/redirect?z=https%3A%2F%2Fesc.gsfc.nasa.gov%2Ftdrs&t=OTVkMGZmZWNlYTNlODAyM2MzZTc3M2QzYzMxNjAzY2U1MzAyYWZjZCxQdG5mZk9nQQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F177093627469%2Fin-conversation-with-the-sun-parker-solar-probe&m=0) (TDRS) enabled constant communications coverage for the rocket as Parker made its way out of Earth's atmosphere. These satellites fly in geosynchronous orbit, circling Earth in step with its rotation, relaying data from spacecraft at lower altitudes to the ground. The network's three collections of TDRS over the Atlantic, Pacific and Indian oceans provide enough coverage for continuous communications for satellites in low-Earth orbit.

    The Near Earth Network's Launch Communications Segment tracked early stages of Parker's launch, testing our brand new ground stations' ability to provide crucial information about the rocket's initial velocity (speed) and trajectory (path). When fully operational, it will support launches from the Kennedy spaceport, including upcoming Orion (https://t.umblr.com/redirect?z=https%3A%2F%2Fwww.nasa.gov%2Fexploration%2Fsystems%2Forion%2Findex.html&t=YjMxNTE5NDBmNWVkZjAxN2MxZjAwZWRkNGRjMmFiNTRjZjgwM2I2YSxQdG5mZk9nQQ%3D%3D&b=t%3AUFcrB_DpY1hYQssYTNl5fw&p=https%3A%2F%2Fnasa.tumblr.com%2Fpost%2F177093627469%2Fin-conversation-with-the-sun-parker-solar-probe&m=0) missions. The Launch Communications Segment's three ground stations are located at Kennedy Space Center; Ponce De Leon, Florida; and Bermuda.

    When Parker separated from the Delta IV Heavy, the Deep Space Network took over. Antennas up to 230 feet in diameter at ground stations in California, Australia and Spain are supporting Parker for its 24 orbits around the Sun and the seven Venus flybys that gradually shrink its orbit, bringing it closer and closer to the Sun. The Deep Space Network is delivering data to mission operations centers and will continue to do so as long as Parker is operational.

    https://www.youtube.com/watch?v=RGhyjX4opD8 (https://www.youtube.com/watch?v=RGhyjX4opD8)
    Near the Sun, radio interference and the heat load on the spacecraft's antenna makes communicating with Parker a challenge that we must plan for. Parker has three distinct communications phases, each corresponding to a different part of its orbit.

    When Parker comes closest to the Sun, the spacecraft will emit a beacon tone that tells engineers on the ground about its health and status, but there will be very little opportunity to command the spacecraft and downlink data. High data rate transmission will only occur during a portion of Parker's orbit, far from the Sun. The rest of the time, Parker will be in cruise mode, taking measurements and being commanded through a low data rate connection with Earth.

    Communications infrastructure is vital to any mission. As Parker journeys ever closer to the center of our solar system, each byte of downlinked data will provide new insight into our Sun. It's a mission that continues a conversation between us and our star that has lasted many millions of years and will continue for many millions more.

    Space missions dispatched into the solar system often have journeys lasting years before reaching a scientific payoff, but NASA's Parker Solar Probe launched last weekend on a speedy departure fr om planet Earth is already getting ready to sweep closer to the sun than any spacecraft in history during a flyby later this year.

    The armored spacecraft lifted off Sunday, Aug. 12, from Cape Canaveral on top of a United Launch Alliance Delta 4-Heavy rocket, one of the most powerful launchers in the world.

    Sometimes used to launch satellites as big as a school bus, the Delta 4-Heavy and a kick motor shot Parker Solar Probe -- the size of a small car -- into space with enough speed to reach Venus in just 52 days, the fastest-ever journey to from Earth to another planet.

    Parker Solar Probe will slingshot past Venus, with the craft's closest approach expected Oct. 3 at 4:44 a.m. EDT (0844 GMT) to redirect its orbit closer to the sun. The gravity assist flyby will set up the solar probe for its first perihelion -- or close approach to the sun -- on Nov. 5 at 10:27 p.m. EST (0327 GMT on Nov. 6).

    Those dates changed slightly after launch delays pushed back Parker Solar Probe's liftoff from an original target date of July 31.

    In November, the spacecraft will reach a point in its elliptical, oval-shaped orbit roughly 15 million miles (24.1 million kilometers) from the sun's surface, breaking a record set by the U.S.-German Helios 2 mission, which passed as close as 27 million miles (43.4 million kilometers) from the sun in April 1976.
    Parker Solar Probe carries four instrument packages to measure magnetic and electric fields, detect, count and characterize particles in the solar wind and inside the sun's atmosphere, and take white light images inside the sun's corona.

    The $1.5 billion mission has been on NASA's to-do list for six decades, since the agency's formation and the first prediction of the solar wind by Eugene Parker, a University of Chicago physicist whose hypotheses about the supersonic stream of particles emanating from the sun were later confirmed by early space missions.

    NASA named the solar probe for Parker last year, the first time the agency has named a science mission for a living person. Parker, 91, traveled to the Kennedy Space Center for the Aug. 12 launch.

    The 1,424-pound (646-kilogram) spacecraft separated from a kick stage that launched atop the Delta 4-Heavy less than 45 minutes after liftoff last Sunday. A few minutes later, ground controllers confirmed the probe extended its two solar panels to begin generating electricity.

    Parker Solar Probe's high-gain antenna, designed to downlink science data to Earth, was released from its launch locks Aug. 13. The mission's autonomous control system, which uses fast-spinning reaction wheels and thrusters, has also been activated as planned, according to an update released Friday by NASA and the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, which built the spacecraft.

    The spacecraft also powered up the first of four instrument suites beginning Aug. 13. The spacecraft released clamps holding four of five antennas comprising the FIELDS instrument. The roughly 6-foot-long (2-meter) antennas will be deployed around 30 days after launch to stick out from behind the probe's heat shield, exposing the sensors to the harsh environment of the corona for measurements of electric and magnetic fields, plasma waves, and interplanetary radio emissions.

    Parker Solar Probe also extended its magnetometer boom, which holds three magnetometers and a smaller, fifth antenna that is part of the FIELDS instrument suite.

    "Parker Solar Probe is operating as designed, and we are progressing through our commissioning activities," Andy Driesman, the mission's project manager at APL. "The team - which is monitoring the spacecraft 24 hours a day, seven days a week - is observing nominal data from the systems as we bring them online and prepare Parker Solar Probe for its upcoming initial Venus gravity assist."

    Scientists will have to wait more than six years for Parker Solar Probe's closest encounter with the sun, but the mission could produce results well before then.

    "In our very first flyby of the corona (in November), we get to a little more than 15 million miles from the sun's surface," said Nicola Fox, Parker Solar Probe's project scientist at APL. "We're already in a ... very, very interesting coronal area. In fact, one of the key things about our early orbits is we're actually just sort of at this sweet spot.

    "As we're rotating around the sun, the sun is rotating at the same time, the same speed," Fox said. "If you think about it in that frame, the spacecraft is staying over the same area of the sun for many, many days, allowing us to do some incredible science on our very first flyby."

    The first perihelion in November will also return data to help scientists fully calibrate the spacecraft's science instruments.

    Six more Venus flybys will spiral Parker Solar Probe ever-closer to the sun, redirecting the craft's trajectory toward its closest encounter with the sun at a range of 3.83 million miles (6.16 million kilometers) in 2024, roughly 4 percent the distance of the sun from Earth.

    At that distance, the sun's gravity will whip Parker Solar Probe around in its orbit at a velocity of up to 430,000 mph (nearly 700,000 kilometers per hour), fast enough to travel from Philadelphia to Washington, D.C., in one second.

    Reaching such immense speeds requires -- perhaps counterintuitively -- that Parker Solar Probe to first slow down, allowing solar gravity to pull it closer to the sun.

    "Venus is very important to us," Fox said. "We actually use Venus to do gravity assists. Not like other missions you've heard about that take energy from the planet to speed up, we actually generously give energy to Venus, and we use Venus to slow us down just a little bit, really to focus our orbit, almost like doing a little handbrake turn and focusing us in towards the sun. We will do 24 petal orbits, coming very close to the sun on one side, going out around the orbit of Venus on the other."

    Parker Solar Probe will fly through the corona, a super-heated envelope of plasma surrounding the sun wh ere temperatures soar to millions of degrees. The temperature at the surface of the sun is hundreds of times cooler, but still a scorching 10,000 degrees Fahrenheit (6,000 degrees Celsius).

    (https://mk0spaceflightnoa02a.kinstacdn.com/wp-content/uploads/2018/08/psp_traj.jpg)

    The corona is also thought by scientists to be the origin of the solar wind, a flow of charged particles flowing away from the sun in every direction, influencing the entire solar system and driving space weather.

    "How is the solar wind accelerated up to millions of miles per hour very quickly in the solar corona? The work that Dr. Parker has laid out is the foundational work for understanding this process, and this is one of the primary goals of the Parker Solar Probe," said Alex Young, associate director for science in the heliophysics division at NASA's Goddard Space Flight Center in Maryland.

    "Why does this all matter? We're living in this dynamic sun's atmosphere. We're living in the solar wind streaming by the Earth, streaming by other planets," Young said. "We see the beautiful results with the aurora, but this also creates an incredibly dynamic environment that impacts our technology, makes the environment hostile for astronauts, and in the most extreme cases, can even impact technology and power grids here on Earth."

    A heat shield made of two carbon-carbon panels sandwiching a carbon foam core will protect most of the spacecraft from the blistering conditions in the corona. The heat shield's sun-facing side also has a sprayed-on white coating to reflect as much of the sun's heat as possible.

    "We will be orbiting through the 3-million-degree plasma region," Fox said. "That sounds really hot, but the plasma there is not very dense. If you imagine turning your oven on to 400 degrees and letting it heat up, you could put your hand inside that oven. It won't burn you unless you touch something, so there's a difference between temperature and heat.

    "There aren't that many particles around, so the actual amount that couples into the front side of our heat shield means that the front side is about 2,500 degrees Fahrenheit, or 1,400 degrees Centigrade (Celsius)," Fox said.

    Behind the heat shield, or thermal protection system, the main body of the spacecraft will be warmed a little hotter than room temperature, but still within engineering tolerances for crucial parts like the probe's computer and propulsion system.

    But some parts of the spacecraft, such as its science instrumentation and solar panels, will be exposed to the hot corona.

    "We are very happy that we are well protected," Fox said. "We have a full suite of instruments to make the measurements that are so key and important for us to be able to close the science. So we have instruments that measure all of the magnetic and electric fields, they're looking for plasma waves, the very high-energy particles, and we also have a while light imager that is taking pictures of basically what we're about to plow through. So we have a full suite of instruments."

    Engineers designed a cooling system using five liters of water to keep the craft's sensitive solar cells from overheating.

    "Solar cells need to stay cool," Fox said. "They don't like to overheat and if they do, they don't work. So we (had) to find a way to cool our panels as we are making these cuts through the corona."

    When Parker Solar Probe is closest to the sun, its on-board computer will automatically adjust its pointing, the performance of the cooling system, and other factors to keep the spacecraft safe. Ground controllers will not be able to uplink commands in real-time as the spacecraft transits through the corona.

    "She is the most independent spacecraft, she's highly, highly autonomous," Fox said. "She has to look after herself when she's in this coronal region. There is no person in the loop, she is fully capable of figuring out if there's an anomaly how to rectify it. It takes light eight minutes to get from the sun to the Earth, we don't have time for her to send a signal so we can think about it and send it back. She has to be able to look after herself."

    Parker Solar Probe will radio a beacon signal back to Earth as it flies through the corona, but ground commands and high-speed data downlinks will have to wait for times when the spacecraft is farther from the sun.

    "These are kind of the big technology leaps we've had to make," Fox said. "That is why we've had to wait 60 years for this mission."

    ЦитатаAfter Near-Perfect Trajectory Maneuver, Parker Solar Probe On Course To Touch The Sun

    Sarah Frazier (https://blogs.nasa.gov/parkersolarprobe/author/sfrazie2/)
    Posted Aug 21, 2018 at 10:00 am


    At 6:07 a.m. EDT on Aug. 20, 2018, NASA's Parker Solar Probe successfully completed its first trajectory correction maneuver (known as TCM-1), achieving a near-perfect firing of its propulsion system and putting the spacecraft on course to "touch" the Sun. This maneuver sets up the orbital geometry that will allow Parker Solar Probe to come within about 3.83 million miles (8.86 solar radii) of the Sun's surface on its closest approach in 2024.

    Following launch at 3:31 a.m. EDT on Aug. 12, the spacecraft control team at the Johns Hopkins Applied Physics Laboratory, or APL, in Laurel, Maryland, analyzed Parker Solar Probe's position and quickly developed a re-optimized trajectory to place it in the best path for the seven Venus gravity assist maneuvers and 24 solar orbits that the mission will make. Re-assessing a spacecraft's trajectory after launch is a normal step, as the mission team is then able to accurately track the spacecraft's actual speed, direction and position to create a more precise trajectory plan.

    Spacecraft controllers at the mission operation center initiated the two-part TCM-1 beginning at 6:00 a.m. EDT on Aug. 19 with a 44-second burn of the engines. The majority of the engine firing, which lasted just over seven minutes, began at 6:00 a.m. EDT on Aug. 20.

    "TCM-1 is one of the critical events of the mission and a major mission milestone," said Parker Solar Probe mission design and navigation manager Yanping Guo, from APL. "In the future, we only need to fine-tune the trajectory periodically, and no major adjustments or large maneuvers will be required unless something unusual happens. In short: We are on our way to touch the Sun!"

    "The team completely nailed this maneuver," said APL's Andy Driesman, Parker Solar Probe project manager. "Execution of the burn was exceptional, measuring at less than 0.2 percent magnitude error--which translates to a 0.3 standard deviation, or sigma, from optimal. We had defined success for TCM-1 as up to 3 sigma, which really illustrates how phenomenally this was executed."

    As of 12:00 p.m. EDT on August 20, Parker Solar Probe was 5.5 million miles from Earth, travelling at 39,500 miles per hour.

    JPL Roles in NASA's Sun-Bound Parker Solar Probe

    The navigation for NASA's Parker Solar Probe is led by the agency's Jet Propulsion Laboratory in Pasadena, California, which also has a role in two of the spacecraft's four onboard instrument suites. Parker Solar Probe will fly closer to the Sun than any previous spacecraft and through the solar corona itself.
    One instrument, called the Energetic Particle Instrument-Hi (EPI-Hi), will investigate the mysteries of high-speed solar particles that hurtle toward Earth at close to the speed of light. Observations by the Parker Solar Probe will lead to better predictions of space weather and address fundamental mysteries about the Sun's dynamic corona. EPI-Hi is part of the Integrated Science Investigation of the Sun, led by Principal Investigator David McComas of Princeton University in New Jersey.

    "We will be exploring a region of space that has never before been visited," said Mark Wiedenbeck, the lead investigator on the EPI-Hi instrument and a principal research scientist at JPL. "We have ideas about what will be found, but the most important results may well come fr om observations that are completely unexpected."

    Of particular interest to the EPI-Hi team is the unsolved riddle of how a small fraction of the charged particles from the Sun reach near-light speeds. These particles, protons, electrons and heavy ions can reach Earth in less than an hour, creating space weather hazards to humans and hardware in space. Until now, scientists had been observing from a distance the effects of what is happening near the Sun. With the Parker Solar Probe now on its way to fly through the region wh ere it is happening, scientists are confident they will obtain new clues and insight into the process.

    The EPI-Hi instrument consists of stacks of silicon detectors designed to snag high-speed particles and measure their energies. Some of the detectors are very thin, with the thinnest being about one-eighth the thickness of a standard sheet of paper. For the detectors to make the required measurements, the thickness of these detectors could vary by no more than one-hundredth the thickness of a sheet of paper.

    Another instrument on Parker Solar Probe -- the Wide-Field Imager for Solar Probe Plus (WISPR) - is the only camera aboard the spacecraft. It will take images of the Sun's corona and inner heliosphere. The imager has two telescopes that will capture images of the solar wind, shock waves and other coronal structures as they approach and pass the spacecraft. WISPR provides a very wide field-of-view, extending from 13 degrees away from the center of the Sun to 108 degrees away.

    (video (https://www.youtube.com/watch?time_continue=1&v=8ZEwvQL486o) 0:20)
    This animation shows Parker Solar Probe flying through the solar corona and coronal mass ejections. The fields of view of the two WISPR telescopes are defined by the pyramid-shaped rays coming from WISPR instrument. When approaching the Sun, the spacecraft flies such that its heat shield is always facing the Sun to protect the instruments and spacecraft from the intense solar radiation. As it gets closer to the Sun, the solar panels are folded back behind the shield so that only the tips are exposed to sunlight. The animation also shows how WISPR uses the heat shield to block out the direct sunlight so it can view the corona, which is seen in reflected sunlight.

    "If you saw the solar eclipse last August, you saw the Sun's corona. That is our destination. WISPR will be taking images of the corona as it flies through it. The images will help us understand the morphology, velocity, acceleration and density of evolving solar wind structures when they are close to the Sun," said JPL scientist Paulett Liewer, a member of the WISPR Science Team. The WISPR principal pnvestigator is Russell Howard of the Naval Research Laboratory.

    In leading Parker's navigation efforts, JPL is helping to implement the mission's innovative trajectory, developed by the Johns Hopkins Applied Physics Laboratory, Laurel, Maryland, which built and operates the spacecraft for NASA. The Parker Solar Probe will use seven Venus flybys over nearly seven years to gradually shrink its orbit around the Sun, coming as close as 3.83 million miles (6.16 million kilometers) to the Sun, well within the orbit of Mercury and about seven times closer to the Sun than any spacecraft before.

    In addition, the Parker Solar Probe Observatory Scientist, Principal Investigator Marco Velli, a UCLA professor, holds a part-time appointment as Heliophysics Liaison to NASA at JPL.

    The Parker Solar Probe lifted off on Aug. 12, 2018, on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex-37 at Cape Canaveral Air Force Station in Florida. The mission's findings will help researchers improve their forecasts of space weather events, which have the potential to damage satellites and harm astronauts on orbit, disrupt radio communications and, at their most severe, overwhelm power grids.

    EPI-Hi is managed for NASA by Caltech in collaboration with JPL, which is a division of Caltech. The Parker Solar Probe is part of NASA's Living with a Star Program, or LWS, to explore aspects of the Sun-Earth system that directly affect life and society. LWS is managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland, for the Heliophysics Division of NASA's Science Mission Directorate in Washington. Johns Hopkins APL manages the Parker Solar Probe mission for NASA.

    experience some particularly harsh conditions. We constructed a mechanical model of the
    L0 detector having a thin silicon membrane of the same diameter but only 80 % of the L0

    level of 143 dB.
    The model came through this test undamaged.

    NASA's historic Parker Solar Probe mission that launched Aug. 12, 2018 from Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida will revolutionize our understanding of the Sun. The Parker Solar Probe spacecraft will travel through the Sun's atmosphere, closer to the surface than any spacecraft before it, facing brutal heat and radiation conditions -- and ultimately providing humanity with the closest-ever observations of a star. This is a look at the moments leading up to T-Zero for NASA's mission to "touch" the Sun.

    ЦитатаParker Solar Probe Continues Successful Commissioning Operations

    Sarah Frazier (https://blogs.nasa.gov/parkersolarprobe/author/sfrazie2/)
    Posted Sep 5, 2018 at 10:31 am


    Parker Solar Probe continues to bring its instruments and secondary systems online -- slightly ahead of schedule -- as it speeds away from Earth.

    On Friday, Aug. 31, flight controllers at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland performed a second planned Trajectory Correction Maneuver (TCM-2), a thruster burn which lasted for seven minutes and five seconds. This maneuver, which was executed with a high degree of precision, adjusted the direction of the spacecraft to position it for its Venus flyby on Oct. 3, when it will use Venus' gravity (https://www.nasa.gov/feature/goddard/2018/its-surprisingly-hard-to-go-to-the-sun) to shed speed and draw its orbit closer to the Sun in preparation for its first solar approach.

    On Sept. 2, four two-meter electric field antennas, part of the FIELDS instrument suite, were deployed. These antennas (as well as a fifth, which is mounted on the long boom at the other end of Parker Solar Probe) need to be extended away from the spacecraft to accurately measure the electric fields of the corona. These four antennas are not protected by Parker Solar Probe's Thermal Protection System, or heat shield, so they are made of niobium C-103, a high-temperature alloy that can withstand the intense solar heat.

    Just a few hours after the FIELDS antennas were deployed, the Solar Wind Electrons Alphas and Protons (SWEAP) investigation team successfully opened the covers of two instruments, the Solar Probe Analyzer (SPAN) instruments. The SPAN instruments are used to measure the solar wind when it is coming in at an angle relative to the spacecraft.

    Before opening the SPAN instrument doors, the team ramped up high voltages on the Solar Probe Cup (SPC) instrument, also part of SWEAP. Solar Probe Cup measures the thermal solar wind plasma flowing radially from the Sun -- requiring this instrument to be mounted outside the heat shield and pointed directly at the Sun. Like the FIELDS antennas, Solar Probe Cup is constructed of niobium C-103.

    Other systems and instruments have completed checkouts as well. The spacecraft's high gain antenna -- which will be used to send high-rate science data to Earth -- has been moved through its full range of motion.

    EPI-Lo and EPI-Hi, the two Energetic Particle Instruments that make up the IS☉IS suite (pronounced "ee-sis" and short for Integrated Science Investigation of the Sun), have been turned on and have completed low voltage checks.

    The Wide-field Imager for Solar Probe (WISPR) instrument has been turned on and has taken closed-door test images to calibrate the systems and imagers.

    "The spacecraft continues to perform as designed, and thanks to the team's careful planning and execution, we're commissioning instruments slightly ahead of schedule," said APL's Andy Driesman, Parker Solar Probe project manager.

    "The science team is excited to begin the investigation phase of the mission," said Nour Raouafi of APL, Parker Solar Probe project scientist. "We're looking forward to seeing this initial science data and getting our first look at what we know will be many discoveries that Parker Solar Probe will make."
    As of 12 p.m. EDT on Sept. 4, Parker Solar Probe was more than 15 million miles from Earth, travelling at about 44,700 miles per hour (72,000 kilometers per hour).

    ЦитатаParker Solar Probe's Solar Array Cooling System Fully Activated

    Sarah Frazier (https://blogs.nasa.gov/parkersolarprobe/author/sfrazie2/)
    Posted Sep 14, 2018 at 3:00 pm


    On Sept. 13, Parker Solar Probe's first-of-its-kind water-cooled Solar Array Cooling System (or SACS) was made fully operational. The SACS will protect Parker Solar Probe's solar arrays -- responsible for powering the spacecraft -- from the intense heat of the Sun.

    Though the solar arrays rely on the Sun's energy to create electrical power for the spacecraft, they're also very sensitive to overheating, and Parker Solar Probe is the first scientific mission to use a water-cooled solar array thermal management system. Water flows through mini-channels embedded in the solar arrays to absorb heat, then flows into four radiators to release that heat into space. This keeps the solar panels cool while near the Sun, allowing them to efficiently generate power for the spacecraft.

    Though the Sun-facing side of Parker Solar Probe's heat shield will reach temperatures as high as 2,500 degrees Fahrenheit when the spacecraft is close to the Sun, the SACS will keep the solar arrays -- partially exposed to the Sun's direct radiation -- at less than 302 degrees.
    (https://blogs.nasa.gov/parkersolarprobe/wp-content/uploads/sites/274/2018/09/dpsponthirdstage-0-659x1024.jpg) (https://blogs.nasa.gov/parkersolarprobe/wp-content/uploads/sites/274/2018/09/dpsponthirdstage-0.jpg)

    As planned, the cooling system came partially online shortly after launch on Aug. 12. Roughly one hour after Parker Solar Probe's 3:31 a.m. EDT launch, the spacecraft autonomously released the launch locks on its two solar arrays and deployed the panels. The spacecraft then released approximately two-thirds of a gallon of deionized water from a heated tank into two of four large radiators, mounted just below the spacecraft's heat shield.

    Then on Sept. 13, at around 11 p.m. EDT -- when the spacecraft had reached a distance of about 84 million miles (135 million kilometers) from the Sun -- the remaining one-third of a gallon of water was released, activating the last two radiators and making the SACS fully operational. These events were controlled by the mission operations team at the Johns Hopkins Applied Physics Lab in Laurel, Maryland.

    "There are a number of technological breakthroughs on Parker Solar Probe that make the mission possible," said APL's Andy Driesman, project manager for mission. "The Solar Array Cooling System is really the heart and circulatory system of the spacecraft. Without it, the solar arrays would not survive the heat from the Sun, and we would not be able to operate the instruments that will explore the Sun's corona and the systems that protect the spacecraft from the intense solar environment."

    As of 12 p.m. EDT on Sept. 14, Parker Solar Probe was 21 million miles (34 million km) from Earth, traveling at about 51,000 miles per hour (82,000 kph). Track the spacecraft's progress online (http://parkersolarprobe.jhuapl.edu/The-Mission/index.php#Where-Is-PSP).

    Posted Sep 19, 2018 at 12:01 pm


    Just over a month into its mission, Parker Solar Probe has returned first-light data from each of its four instrument suites. These early observations - while not yet examples of the key science observations Parker Solar Probe will take closer to the Sun - show that each of the instruments is working well. The instruments work in tandem to measure the Sun's electric and magnetic fields, particles from the Sun and the solar wind, and capture images of the environment around the spacecraft.

    "All instruments returned data that not only serves for calibration, but also captures glimpses of what we expect them to measure near the Sun to solve the mysteries of the solar atmosphere, the corona," said Nour Raouafi, Parker Solar Probe project scientist at the Johns Hopkins University Applied Physics Lab in Laurel, Maryland.

    The mission's first close approach to the Sun will be in November 2018, but even now, the instruments are able to gather measurements of what's happening in the solar wind closer to Earth. Let's take a look at what they've seen so far.

    WISPR (Wide-field Imager for Solar Probe)
    As the only imager on Parker Solar Probe, WISPR will provide the clearest-yet glimpse of the solar wind from within the Sun's corona. Comprising two telescopes, WISPR sits behind the heat shield between two antennae from the FIELDS instrument suite. The telescopes were covered by a protective door during launch to keep them safe.

    WISPR was turned on in early September 2018 and took closed-door test images for calibration. On Sept. 9, WISPR's door was opened, allowing the instrument to take the first images during its journey to the Sun.

    (https://blogs.nasa.gov/parkersolarprobe/wp-content/uploads/sites/274/2018/09/01_WISPR-crop.png) (https://blogs.nasa.gov/parkersolarprobe/wp-content/uploads/sites/274/2018/09/01_WISPR-crop.png)
    The right side of this image -- from WISPR's inner telescope -- has a 40-degree field of view, with its right edge 58.5 degrees from the Sun's center. The left side of the image is from WISPR's outer telescope, which has a 58-degree field of view and extends to about 160 degrees from the Sun. There is a parallax of about 13 degrees in the apparent position of the Sun as viewed from Earth and from Parker Solar Probe. Credit: NASA/Naval Research Laboratory/Parker Solar Probe

    Download these images in HD formats from NASA's Scientific Visualization Studio.  (https://svs.gsfc.nasa.gov/13072)

    Russ Howard, WISPR principal investigator from the Naval Research Laboratory, studied the images to determine the instrument was pointing as expected, using celestial landmarks as a guide.

    "There is a very distinctive cluster of stars on the overlap of the two images. The brightest is the star Antares-alpha, which is in the constellation Scorpius and is about 90 degrees from the Sun," said Howard.

    The Sun, not visible in the image, is far off to the right of the image's right edge. The planet Jupiter is visible in the image captured by WISPR's inner telescope -- it's the bright object slightly right of center in the right-hand panel of the image.

    "The left side of the photo shows a beautiful image of the Milky Way, looking at the galactic center," said Howard.

    The exposure time - i.e. the length of time that light was gathered for this image, an interval which can be shortened or lengthened to make the image darker or brighter - is on the lower end, and there's a reason: "We intentionally wanted to be on the low side in case there was something very bright when we first turned on, but it is primarily because we are looking so far from the Sun," explains Howard.

    As the spacecraft approaches the Sun, its orientation will change, and so will WISPR's images. With each solar orbit, WISPR will capture images of the structures flowing out from the corona. While measurements have been made before by other instruments at a distance of 1 AU - or approximately 93 million miles - WISPR will get much closer, about 95% of the way to the Sun from Earth, dramatically increasing the ability to see what's occurring in that region with a much finer scale than ever before and providing a more pristine picture of the solar corona.
    ISʘIS (Integrated Science Investigation of the Sun)
    (https://blogs.nasa.gov/parkersolarprobe/wp-content/uploads/sites/274/2018/09/02_ISIS-1024x392.png) (https://blogs.nasa.gov/parkersolarprobe/wp-content/uploads/sites/274/2018/09/02_ISIS.png)
    Credit: NASA/Princeton University/Parker Solar Probe

    ISʘIS (pronounced "ee-sis" and including the symbol for the Sun in its acronym) measures high-energy particles associated solar activity like flares and coronal mass ejections. (The mission's other particle instrument suite, SWEAP, focuses on low-energy particles that make up the solar wind.) ISʘIS' two Energetic Particle Instruments cover a range of energies for these activity-driven particles: EPI-Lo focuses on the lower end of the energy spectrum, while EPI-Hi measures the more energetic particles. Both instruments have gathered data under low voltage, making sure their detectors work as expected. As Parker Solar Probe approaches the Sun, they will be fully powered on to measure particles within the Sun's corona.

    EPI-Lo's initial data, on the left, shows background cosmic rays, particles that were energized and came rocketing into our solar system from elsewh ere in the galaxy. As EPI-Lo's high voltage is turned on and Parker Solar Probe gets closer to the Sun, the particles measured will shift toward solar energetic particles, which are accelerated in bursts and come streaming out from the Sun and corona.

    On the right, data from EPI-Hi shows detections of both hydrogen and helium particles from its lower-energy telescopes. Nearer to the Sun, scientists expect to see many more of these particles -- along with heavier elements -- as well as some particles with much higher energies, especially during solar energetic particle events.

    "The ISʘIS team is delighted with instrument turn-on so far," said David McComas, Professor of Astrophysical Sciences at Princeton University and principal investigator of the ISʘIS instrument suite. "There are a few more steps to go, but so far everything looks great!"
    FIELDS
    The FIELDS instrument suite aboard Parker Solar Probe captures the scale and shape of electric and magnetic fields in the Sun's atmosphere. These are key measurements to understanding why the Sun's corona is hundreds of times hotter than its surface below.

    FIELDS' sensors include four two-meter electric field antennas -- mounted at the front of the spacecraft, extending beyond the heat shield and exposed to the full brunt of the solar environment -- as well as three magnetometers and a fifth, shorter electric field antenna mounted on a boom that extends from the back of the spacecraft.

    The data above, gathered during the boom deployment shortly after the spacecraft's launch in August, shows how the magnetic field changes as the boom swung away from Parker Solar Probe. The early data is the magnetic field of the spacecraft itself, and the instruments measured a sharp drop in the magnetic field as the boom extended away from the spacecraft. Post-deployment, the instruments are measuring the magnetic field in the solar wind -- illustrating the very reason such sensors need to be held out far from the spacecraft.

    In early September, the four electric field antennas on the front of the spacecraft were successfully deployed -- and almost immediately observed the signatures of a solar flare.

    "During its commissioning time, FIELDS measured its first radio burst from a solar flare," said principal investigator Stuart Bale, of the Space Sciences Laboratory at the University of California, Berkeley. Such bursts of radio waves can be detected during solar flares -- enormous eruptions of energy and light -- and are associated with the energetic electrons that flares release. This radio burst was captured by the FIELDS electric field antennas, shown above with measurements from NASA's Wind spacecraft (https://wind.nasa.gov/) (on the top) for comparison.

    "FIELDS is one of the most comprehensive fields and waves suites ever flown in space, and it is performing beautifully," said Bale.

    The SWEAP suite includes three instruments: Two Solar Probe Analyzers measure electrons and ions in the solar wind, while the Solar Probe Cup sticks out from behind Parker Solar Probe's heat shield to measure the solar wind directly as it streams off the Sun. After opening covers, turning on high voltages and running internal diagnostics, all three instruments caught glimpses of the solar wind itself.

    Because of Parker Solar Probe's position and orientation, the science team expected that Solar Probe Cup would mostly measure background noise at first, without picking up the solar wind. But just after the instrument was powered on, a sudden, intense gust of solar wind blew into the cup, visible in the data as the red streak. As the spacecraft approaches the Sun, such observations will be Solar Probe Cup's bread and butter -- and will hopefully reveal new information about the processes that heat and accelerate the solar wind.

    The two Solar Probe Analyzers (SPAN) also caught early peeks of the solar wind. During commissioning, the team turned the spacecraft so that SPAN-A -- one of the two SPAN instruments -- was exposed to the solar wind directly. It captured about 20 minutes' worth of data (right), including measurements of solar wind ions (top) and electrons (bottom). While SPAN-A and its sister instrument, SPAN-B, will measure solar wind electrons throughout the mission, the spacecraft's orientation now means that SPAN-A will likely go several more years before it captures such ion measurements again. This is because solar wind electrons can be measured from any direction, as their low mass and high temperature make their motion much more random, while the much heavier solar wind ions follow a relatively direct path out from the Sun.

    "SWEAP's solar wind and corona plasma instrument performance has been very promising," said Justin Kasper, principal investigator of the SWEAP instrument suite at University of Michigan. "Our preliminary results just after turn-on suggest we have a set of highly sensitive instruments that will allow us to do amazing science close to the Sun."

    Three NASA Missions Return 1st-Light Data

    NASA's continued quest to explore our solar system and beyond received a boost of new information this week with three key missions proving not only that they are up and running, but that their science potential is exceptional. On Sept. 17, 2018, TESS (http://nasa.gov/tess) -- the Transiting Exoplanet Survey Satellite -- shared its first science observations. Later in the week, the latest two missions to join NASA's heliophysics fleet returned first light data: Parker Solar Probe, (https://www.nasa.gov/feature/goddard/2018/nasa-prepares-to-launch-parker-solar-probe-a-mission-to-touch-the-sun) humanity's first mission to "touch" the Sun, and GOLD (https://www.nasa.gov/feature/goddard/2018/nasa-gold-mission-to-image-earth-s-interface-to-space), a mission that studies the dynamic boundary between Earth and space.
    ...
    Together, the two other missions represent two key observation points in the giant system of space -- dominated by particles and magnetic energy from the Sun -- studied by the field of heliophysics. Parker Solar Probe will help us understand how the Sun's atmosphere drives particles out into space; ... The two viewpoints support heliophysics' focus on our star and how it influences the very nature of space -- and, in turn, the atmospheres of planets and human technology.

    In early September, each of Parker Solar Probe's four instrument suites (http://parkersolarprobe.jhuapl.edu/Spacecraft/index.php#Instruments) powered on and returned their first observations (https://blogs.nasa.gov/parkersolarprobe/2018/09/19/illuminating-first-light-data-from-parker-solar-probe/) on the spacecraft's journey to the Sun. While the data are not yet examples of the key science observations the spacecraft will take closer to the Sun, they show that each of the instruments is working well.

    The instruments work in tandem to measure the Sun's electric and magnetic fields, and particles from the Sun and solar wind. They also capture images of the solar wind environment around the spacecraft. The mission's first close approach to the Sun will be in early November 2018, but even now, still outside the orbit of Venus, the instruments indicate they're ready to gather measurements of what's happening in the solar wind.

    "All instruments returned data that not only serves for calibration, but also captures glimpses of what we expect them to measure near the Sun to solve the mysteries of the solar atmosphere, the corona," said Nour Raouafi, Parker Solar Probe project scientist at the Johns Hopkins University Applied Physics Lab in Laurel, Maryland.

    These are the first images from WISPR, short for the Wide-field Imager for Parker Solar Probe. Researchers studied the images to determine the instrument was pointed as expected, using celestial landmarks as their guide. The left image shows the Milky Way, looking at the galactic center. In the right image, there is a distinctive cluster of four stars near the right edge that is in the constellation Scorpius. The planet Jupiter is also visible in the right image as the bright object slightly right of center. The Sun, not visible in the image, is far off to the right of the image's right edge.

    WISPR, the mission's only onboard imager, captured the first snapshots from its journey to the Sun on Sept. 9, 2018. Similarly, the FIELDS instrument suite provided the first magnetic field observations and even captured a burst of radio waves, signatures of a solar flare. One of the SWEAP instruments sampled its first gust of solar wind, and the ISʘIS instrument -- pronounced "ee-sis" and including the symbol for the Sun in its acronym -- successfully measured the energetic particle environment.
    ...
    Meanwhile, Parker Solar Probe will travel into the blazing corona, closer to the Sun than any spacecraft before it. The mission seeks to answer fundamental questions about the Sun -- questions that lie at the root of understanding how solar activity shapes space weather across the solar system.
    ...
    Parker Solar Probe is part of NASA's Living with a Star Program, or LWS, to explore aspects of the Sun-Earth system that directly affect life and society. LWS is managed by Goddard for the Heliophysics Division of NASA's Science Mission Directorate in Washington. Johns Hopkins APL manages the Parker Solar Probe mission for NASA. APL designed, built and operates the spacecraft.

    We like to call Parker Solar Probe the coolest, hottest, fastest mission under the Sun -- and fall 2018 will prove why. Here are a few mission milestones to look forward to over the coming months.

    Oct. 3, 2018 (about 4:45 a.m. EDT) -- Parker Solar Probe performs its first Venus gravity assist. This maneuver -- to be repeated six more times over the lifetime of the mission -- will change Parker Solar Probe's trajectory to take the spacecraft closer to the Sun.

    (https://blogs.nasa.gov/parkersolarprobe/wp-content/uploads/sites/274/2018/10/Parker-Venus-2-300x166.png)

    Oct. 29, 2018 -- Parker Solar Probe is expected to come within 27 million miles of the Sun. This is the record currently held by Helios 2, set in 1976.

    Oct. 30, 2018 -- Parker Solar Probe is expected to surpass a heliocentric speed of 153,454 miles per hour. This is the record for fastest spacecraft measured relative to the Sun, set by Helios 2 in 1976.

    These speed and distance estimates could change after Parker Solar Probe performs its Venus gravity assist on Oct. 3.

    Oct. 31 - Nov. 11, 2018 -- Parker Solar Probe performs its first solar encounter. Throughout this period, the spacecraft will gather valuable science data. It will not be in contact with Earth because of the Sun's interference and the orientation needed to keep the spacecraft's heat shield between it and the Sun. The spacecraft is expected to reach its closest approach on Nov. 6. Like the distance and speed records, this estimate could change after the Venus gravity assist.

    December 2018 -- Parker Solar Probe will downlink the science data gathered during its first solar encounter.

    On Oct. 3, Parker Solar Probe successfully completed its flyby of Venus at a distance of about 1,500 miles during the first Venus gravity assist of the mission. These gravity assists will help the spacecraft tighten its orbit closer and closer to the Sun over the course of the mission.

    NASA: американский зонд успешно выполнил гравитационный маневр у Венеры на пути к Солнцу

    Такие маневры помогут аппарату приблизиться к солнечной короне

    ВАШИНГТОН, 4 октября. /Корр. ТАСС Дмитрий Кирсанов/. Американская автоматическая станция, предназначенная для исследования Солнца, благополучно выполнила в среду первый гравитационный маневр у Венеры на своем пути к пункту назначения. Об этом сообщило Национальное управление США по аэронавтике и исследованию космического пространства (NASA).

    "Зонд имени Паркера успешно выполнил 3 октября пролет у Венеры на расстоянии примерно 1,5 тыс. миль (2,4 тыс. км)", - отметило космическое ведомство. По его свидетельству, речь идет о "первом гравитационном маневре" с использованием силы притяжения Венеры, предназначенном для изменения траектории полета станции. "Эти гравитационные маневры помогут аппарату переходить на орбиту все ближе и ближе к Солнцу по мере реализации миссии", - пояснило NASA. Согласно изложенной им информации, в течение 7-летней миссии станция должна совершить аналогичный маневр еще шесть раз.

    Детали миссии
    Планируется, что в ноябре зонд приблизится к Солнцу на расстояние в 6,4 млн км. Это означает, что аппарат будет находиться в пределах короны Солнца, то есть внешних слоев его атмосферы, где температура может достигать 500 тыс. кельвинов и даже нескольких миллионов кельвинов.

    По замыслу американских ученых, в период по июнь 2025 года зонд совершит 24 витка по орбите вокруг Солнца, разгоняясь до скорости 724 тыс. км в час. На каждый такой виток у него будет уходить 88 дней.

    На борту аппарата стоимостью порядка $1,5 млрд размещено четыре комплекта научных инструментов. При помощи этой аппаратуры специалисты рассчитывают, в частности, осуществить различные измерения солнечной радиации. Наряду с этим зонд должен будет передать фотоснимки, которые станут первыми, сделанными в пределах солнечной короны. Оборудование зонда защищено оболочкой из углепластика толщиной 11,43 см, позволяющей выдержать температуру до примерно 1,4 тыс. градусов Цельсия.

    Как признала в июне прошлого года координатор данного проекта NASA Никола Фокс, его удалось реализовать только теперь благодаря появлению новых материалов, использованных в первую очередь при создании термостойкого щита зонда. Станция получила и новые панели солнечных батарей, уточнила Фокс. "Мы наконец прикоснемся к Солнцу", - сказала о курируемом проекте эксперт из Лаборатории прикладной физики Университета Джонса Гопкинса. По ее выражению, зонд поможет ученым понять, "как работает Солнце".
    Значение проекта
    NASA обещает, что миссия произведет революцию в представлении человека о процессах, протекающих на Солнце. Претворение в жизнь намеченных планов позволит внести "фундаментальный вклад" в понимание причин "нагревания солнечной короны", а также возникновения солнечного ветра (потока ионизированных частиц, истекающего из солнечной короны) и "ответить на критически важные вопросы в гелиофизике, которые уже на протяжении нескольких десятилетий имеют высший приоритет", убеждено NASA.

    Информация с борта аппарата, по мнению его специалистов, будет иметь огромную ценность и с точки зрения подготовки дальнейших пилотируемых полетов за пределы Земли, поскольку позволит прогнозировать "радиационную обстановку, в которой предстоит работать и жить будущим покорителям космоса".

    Зонд назван в честь выдающегося американского астрофизика Юджина Паркера, которому минувшим летом исполнился 91 год. Паркер стал одним из первых в мире специалистов, занимавшихся исследованиями солнечного ветра. С 1967 года он является членом Национальной академии наук США.

    Предполагается, что зонд Паркера подлетит в семь раз ближе к Солнцу, чем какой-либо другой из космических аппаратов, ранее отправлявшихся человеком.

    Parker Solar Probe Changed the Game Before it Even Launched

    On Oct. 3, 2018, Parker Solar Probe performed the first significant celestial maneuver of its seven-year mission. As the orbits of the spacecraft and Venus converged toward the same point, Parker Solar Probe slipped in front of the planet, allowing Venus' gravity -- relatively small by celestial standards -- to twist its path and change its speed. This maneuver, called a gravity assist, reduced Parker's speed relative to the Sun by 10 percent -- amounting to 7,000 miles per hour -- drawing the closest point of its orbit, called perihelion, nearer to the star by 4 million miles.

    Performed six more times over the course of the seven-year mission, these gravity assists will eventually bring Parker Solar Probe's closest approach to a record 3.83 million miles from the Sun's surface -- about a seventh the distance of the current record-holder, Helios 2, which achieved a pass of 27 million miles from the Sun in 1976. Even before its closest approach, Parker Solar Probe is expected to overtake this record and become the closest human-made object to the Sun in late October 2018.
    A long-held dream
    A solar probe has been on the minds of scientists and engineers for decades, since the late '50s, when a new theory and the first satellite measurements of the Sun's constant outflow of material, called the solar wind, pointed towards previously unsuspected complexity. But if you'd asked anyone before 2007 -- well after serious planning for such a mission began -- Venus would not have come up as the key to the mission puzzle. For the three-plus decades that various committees and teams worked on different concepts for the solar probe mission, it was widely agreed that the only way to dive into the solar atmosphere required sending the spacecraft to Jupiter first.

    "No one believed using Venus gravity assists would be possible, because the gravity assist a planetary body can provide is proportional to the body's mass, and Venus' mass is so much smaller -- only 0.3 percent of Jupiter's," said Yanping Guo, mission design and navigation manager for the Parker Solar Probe mission at the Johns Hopkins University Applied Physics Lab in Laurel, Maryland. " You compare the gravity assist Venus can provide to what Jupiter can provide, and you have to do repeated flybys to achieve the same change. Then you're getting a very long mission duration."

    Getting close to the Sun is more difficult than one might think. Any spacecraft launched from Earth starts off traveling at our planet's 67,000-mile-per-hour sideways pace, speed that it must counteract before it can get anywhere near the Sun. Gravity assists are one of the most powerful tools in an orbit designer's toolbox to solve this problem: Instead of using expensive, precious fuel to change direction or speed (or both), gravity assists let you harness the natural pull of a planet, with time as the only cost.

    Most deep-space missions that use planetary gravity assists use them to gain speed -- like OSIRIS-Rex (https://www.nasa.gov/feature/goddard/2017/asteroid-bound-spacecraft-to-slingshot-past-earth), which used Earth's gravity to rocket towards asteroid Bennu -- or to change direction -- like Voyager 2 (https://solarsystem.nasa.gov/missions/voyager-2/in-depth/), which performed a gravity assist after its final planetary flyby at Neptune to bank toward its moon, Triton.  

    The idea for a solar probe gravity assist was a little different. In the original orbit plans, the primary functions of the Jupiter gravity assist were to slow the spacecraft's speed to almost nothing and fling it upwards, out of the nearly-flat plane that contains all of the known planets of the solar system, called the ecliptic plane. This would put the solar probe on a path to get a rare and better-than-ever look at the Sun's polar regions, which are difficult to image, but important scientifically as they produce some of the Sun's high-speed solar wind. Nearly all of our solar observatories have orbited in the ecliptic plane, with the exception of Ulysses (https://solarsystem.nasa.gov/missions/ulysses/in-depth/), which used a Jupiter gravity assist to achieve polar passes more than 200 million miles from the Sun.

    But sending a spacecraft out to Jupiter and bringing it back into the inner solar system is hard. First, no matter how you plan the journey, it's a long mission, with a minimum of nearly half a decade between meaningful events. Most of the time would be spent cruising in deep space.

    Second, traveling that far from the Sun means you have to get creative with power. Near Jupiter, the sunlight is about 25 times dimmer than what we experience at Earth, so the only options are huge solar panels to make the most of the sparse sunlight, or some other source of power, like nuclear. Large solar panels pose a problem for a solar probe, though, because the panels would need to be shielded during solar encounters to avoid overheating. The size of a solar panel required to power the spacecraft out near Jupiter is too big to effectively stow near the Sun, so they'd have to be jettisoned at perihelion -- and that limits you to just one solar pass, once you've lost your source of power. With nuclear power -- a radioisotope thermoelectric generator, or RTG, the same source that powers deep-space missions like Cassini (https://www.nasa.gov/mission_pages/cassini/main/index.html) and New Horizons (https://www.nasa.gov/mission_pages/newhorizons/main/index.html) -- performing a Jupiter gravity assist is a viable option.
    Changing the mission paradigm
    But the mission design was soon to change. David McComas, chair of the definition committee, remembers a call from Andy Dantzler, then project manager for the Solar Probe mission at APL. Dantzler passed away in 2011 at age 49; the Delta IV Heavy rocket that carried Parker Solar Probe to space was dedicated to him (http://parkersolarprobe.jhuapl.edu/News-Center/Show-Article.php?articleID=102).  

    "Andy asked if there was any way the committee might go for a mission wh ere you stay in the ecliptic plane but have lots of passes by the Sun and slowly reduce the perihelion," said McComas, who is now the principal investigator of the mission's Integrated Science Investigation of the Sun, or ISʘIS, suite and a professor of astrophysical sciences at Princeton University in New Jersey.

    This was an entirely new paradigm for the mission. A hallmark of the original plan was passing over the Sun's poles, the source of the Sun's fast solar wind but a region of relative mystery to scientists. Additionally, staying in the ecliptic plane would almost certainly mean ending up farther from the Sun than had previously been anticipated.

    "If you're trading perihelion distance, you have to swap it for something that will give you opportunities to fill in the science in some other way," said McComas.

    Subsequently, two developments supported the choice to make these changes to the orbit and create the Parker Solar Probe mission we know today.

    The first was new research published in 2009 (https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2009GL039181) by Thomas Zurbuchen -- then a scientist at the University of Michigan and now the associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. This research showed that the solar wind that could be measured from the ecliptic plane was actually from a diverse mix of sources. It was not only the slower solar wind known to be more common near the Sun's equator, but also the high-speed solar wind that often originates closer to the Sun's poles. By sampling the solar wind from the ecliptic plane over a period of years, scientists could learn about this fast solar wind in ways they hadn't previously anticipated.

    The second development was the shift that made such sampling possible: the design of Parker Solar Probe's current trajectory.  

    "When starting, I had no clue if I could find a solution," said Guo, the mission trajectory designer. "Everybody thought Jupiter was the only practical way you could get closer to the Sun, within 10 solar radii."

    In 2007, she came up with five alternative options that would keep the spacecraft near the ecliptic plane and would not require traveling out to Jupiter. These trajectory options used some combination of Earth and Venus gravity assists to gradually draw the spacecraft closer to the Sun over the course of a number of years. One fulfilled all the requirements for the Solar Probe mission -- a total mission duration under 10 years, with a final close approach clocking in under 10 solar radii (equivalent to 4.3 million miles). This was chosen as the trajectory of the current mission, now called Parker Solar Probe after Dr. Eugene Parker (https://www.nasa.gov/content/goddard/eugene-newman-parker), including seven Venus gravity assists that spiral the orbit in closer and closer to the Sun over the mission's seven-year lifetime.

    (https://www.nasa.gov/sites/default/files/styles/full_width/public/thumbnails/image/parker_orbits_v5.jpg?itok=zRDCq4IN) (https://www.nasa.gov/sites/default/files/thumbnails/image/parker_orbits_v5.jpg)
    The final orbit for the Parker Solar Probe mission uses seven Venus gravity assists to rack up more than 900 hours close to the Sun. The original mission concept, using a single Jupiter gravity assist, got the spacecraft closer to the Sun, but gave scientists less than 100 hours in key areas.

    The biggest hurdle to overcome for a trajectory with such repeated gravity assists is phasing. Of course, Venus is in constant motion around the Sun, so every time the spacecraft passes the planet and swings around our star, Venus is in a completely different place. But Guo's design solves that problem, with multiple opportunities for launch. This trajectory design carries the spacecraft through 24 orbits around the Sun. The seven Venus gravity assists happen at different points in the spacecraft's orbit, to account for the phasing problem -- some, like the one on Oct. 3, happen as the spacecraft heads towards the Sun, while the others happen as Parker Solar Probe speeds away from the Sun.

    This orbit is decidedly different than the original single-Jupiter-gravity-assist concept. Rather than two passes over the Sun's poles, coming within 1.23 million miles of the surface, this version of the mission provides 24 passes around the Sun near its equator, coming within 3.83 million miles of the Sun's surface.

    Though Parker Solar Probe doesn't get as close to the Sun, this version of the trajectory provides the spacecraft with more than 900 hours in this critical inner region of the Sun's corona, within 20 solar radii (about 8.65 million miles). In comparison, earlier designs using Jupiter gravity assists provided less than 100 hours in this region.

    "Here was this technical solution that was safer and cheaper and a better scientific mission because of all the samples we'd be getting," said McComas. "The Sun isn't a stable object -- it's variable -- so this would let us do a better scientific job."

    This change to the mission also solved the power problem. Instead of requiring an RTG or unmanageably-large solar panels, Parker Solar Probe is powered by a pair of articulated solar panels that are slowly drawn into the shadow of the heat shield as the spacecraft approaches the Sun. At closest approach, only a small area remains exposed to generate the needed power for the spacecraft, cooled by the mission's first-of-its-kind solar array cooling system.

    But though it solved a major problem, rethinking the mission in this way also required a complete rethinking of the spacecraft itself.

    "The whole spacecraft design changed dramatically," said Nicola Fox, formerly the mission's project scientist at APL. Fox is now the director of the heliophysics division at NASA Headquarters. "With the earlier trajectory, the heat shield was the spacecraft. It was like a cone, with the pointed end facing the Sun, because when you're doing such a fast polar orbit it's tough to keep a shield oriented correctly."

    "We aren't going in as far with the new trajectory, so we could go to a simpler shape for the heat shield, because it's possible to keep the heat shield oriented between the spacecraft and the Sun at all times. The whole thing looks really different."

    The mission team credits Andy Dantzler with guiding them through this fundamental change in the mission's design that led to the mission we know today.

    "When Andy called and asked if the definition team would go for it, I really didn't know the answer," said McComas. "As our definition team worked through the science, I became convinced that it wasn't just an equivalent mission, but actually a better scientific mission, because we get so much more time close to the Sun and so many more samples at different times."
    The first flyby
    During the Oct. 3 gravity assist, Parker Solar Probe came within about 1,500 miles of Venus' surface, reaching this closest point at about 4:45 a.m. EDT.  

    Venus is an interesting case for heliophysicists, who study not only the Sun, but also its effects on planets. Unlike Earth, Venus doesn't have an internal magnetic field -- instead, a weak magnetic field is induced over the surface by the constant barrage of solar charged particles flowing over the planet and interacting with its very dense atmosphere.

    This first flyby offered a unique opportunity for calibration, as Parker Solar Probe flew through the trailing end of Venus' magnetic field, called the magnetotail.  Three of Parker Solar Probe's four instrument suites -- SWEAP, ISʘIS and FIELDS -- gathered data during the flyby on particles and fields in this region.  

    Though the data is still making its way back to Earth, the science team hopes to analyze it before they set their sights on Parker Solar Probe's next major celestial encounter: its first close approach to the Sun. Parker Solar Probe's first solar encounter will happen Oct. 31 - Nov. 11, with the closest approach happening on Nov. 5 at a distance of 15 million miles from the Sun. The science data from this encounter will start downlinking to Earth in early December.

    Parker Solar Probe is part of NASA's Living with a Star program to explore aspects of the Sun-Earth system that directly affect life and society. The Living with a Star program is managed by the agency's Goddard Space Flight Center in Greenbelt, Maryland, for NASA's Science Mission Directorate in Washington. APL designed, built and operates the spacecraft.

    Two days after Parker Solar Probe flew past Venus toward its rendezvous with the Sun, the spacecraft had drawn close enough to our star that its power-generating solar array wings began to tilt themselves inward - a task directed by the spacecraft itself, based on the rising temperatures - away from the Sun and behind the spacecraft's heat shield. This is the first time that autonomous, closed-loop solar array angle control based on temperature has taken place on a spacecraft.

    This solar array movement, controlled by software within the spacecraft's main processor, began on Oct. 5, soon after Parker Solar Probe's distance from the Sun dropped below about 65 million miles.

    Parker Solar Probe Looks Back at Home

    On Sept. 25, 2018, Parker Solar Probe captured a view of Earth as it sped toward the first Venus gravity assist of the mission. Earth is the bright, round object visible in the right side of the image.

    (https://www.nasa.gov/sites/default/files/styles/full_width/public/thumbnails/image/parker-view-of-earth.jpg?itok=radk4BIX) (https://www.nasa.gov/sites/default/files/thumbnails/image/parker-view-of-earth.jpg)

    The image was captured by the WISPR (Wide-field Imager for Solar Probe) instrument, which is the only imaging instrument on board Parker Solar Probe. During science phases, WISPR sees structures within the Sun's atmosphere, the corona, before they pass over the spacecraft. The two panels of WISPR's image come from the instrument's two telescopes, which point in slightly different directions and have different fields of view. The inner telescope produced the left-hand image, while the outer telescope produced the image on the right.

    A close-up of Earth from WISPR's Sept. 25, 2018, image shows what appears to be a bulge on our planet's right side -- this is the Moon.

    Zooming in on Earth reveals a slight bulge on the right side: that is the Moon, just peeking out from behind Earth. At the time the image was taken, Parker Solar Probe was about 27 million miles from Earth.

    The hemispherical shaped feature in the middle of the right-hand image is a lens flare, a common feature when imaging bright sources, which is caused by reflections within the lens system. In this case, the flare is due to the very bright Earthshine. Close passes by Venus and Mercury may occasionally create similar patterns in the future, but these are limited cases and do not affect the science operations of the instrument.

    Some of the visible objects in the image -- like Pleiades to the low-left of Earth in the right-hand image and the two bright objects, Betelgeuse and Bellatrix, near the bottom of the left-hand image -- appear elongated because of reflections on the edge of the detector.

    ЦитатаАмериканский зонд побил рекорд приближения к Солнцу, установленный космическими аппаратами
    ВАШИНГТОН, 30 октября. /Корр. ТАСС Дмитрий Кирсанов/. Американская автоматическая станция имени Юджина Паркера побила рекорд приближения к Солнцу, установленный космическими аппаратами. Об этом сообщило Национальное управление США по аэронавтике и исследованию космического пространства (NASA).
    По его свидетельству, станция, предназначенная для исследования звезды, превзошла 29 октября примерно в 13:04 по времени Восточного побережья США (20:04 мск) прежнее достижение такого рода, принадлежавшее германо-американскому зонду Helios 2. Последний 17 апреля 1976 года приблизился к Солнцу на 43,4 млн км. На сколько именно зонд Паркера обошел державшийся 42 года рекорд, не уточняется. NASA, впрочем, подчеркивает, что теперь аппарат будет подлетать к Солнцу в ходе своей рассчитанной на семь лет миссии все ближе и ближе.
    "Прошло всего 78 дней с момента запуска зонда имени Паркера, а мы уже подобрались к нашей звезде ближе, чем какой-либо другой космической аппарат в истории, - заявил руководитель проекта Энди Дрисмэн из Лаборатории прикладной физики Университета Джонса Гопкинса. - Команда горда, но мы продолжаем концентрировать внимание на нашем первом контакте с Солнцем, который начинается 31 октября". В этот день станция начнет подбираться все ближе к поверхности Солнца, пока не достигнет 5 ноября своего первого перигелия - ближайшей к Солнцу точки орбиты.
    Зонд стартовал 12 августа с космодрома на мысе Канаверал (штат Флорида), он отправился в космос с помощью тяжелой ракеты-носителя Delta IV. Дата запуска несколько раз сдвигалась, в том числе для дополнительного тестирования программного обеспечения систем станции.

    Детали миссии
    Планируется, что в 2024 году зонд приблизится к Солнцу на расстояние около 5 млн км.
    Это означает, что он будет находиться в пределах короны Солнца, то есть внешних слоев его атмосферы, где температура может достигать 500 тыс. кельвинов (около 500 тыс. градусов Цельсия) и даже нескольких миллионов кельвинов.
    По замыслу американских ученых, в период по июнь 2025 года зонд совершит 24 витка по орбите вокруг Солнца, разгоняясь до скорости 724 тыс. км в час. На каждый такой виток у него будет уходить 88 дней.
    На борту аппарата размером с небольшой автомобиль и стоимостью порядка $1,5 млрд размещено четыре комплекта научных инструментов. При помощи этой аппаратуры специалисты рассчитывают, в частности, осуществить различные измерения солнечной радиации. Наряду с этим станция должна будет передать фотоснимки, которые станут первыми, сделанными в пределах солнечной короны. Оборудование зонда защищено оболочкой из углепластика толщиной 11,43 см, позволяющей выдержать температуру до примерно 1,4 тыс. градусов Цельсия.
    Как признала в июне прошлого года прежний координатор проекта Никола Фокс, его удалось реализовать только теперь благодаря появлению новых материалов, использованных в первую очередь при создании термостойкого щита зонда. Станция получила и новые панели солнечных батарей, уточнила Фокс. "Мы наконец прикоснемся к Солнцу", - эмоционально сказала эксперт, ставшая в сентябре директором управления гелиофизики NASA. По ее выражению, зонд поможет ученым понять, "как работает Солнце".
    Значение проекта
    NASA обещает, что миссия произведет революцию в представлении человека о процессах, протекающих на Солнце. Претворение в жизнь намеченных планов позволит внести "фундаментальный вклад" в понимание причин "нагревания солнечной короны", а также возникновения солнечного ветра (потока ионизированных частиц, истекающего из солнечной короны) и "ответить на критически важные вопросы в гелиофизике, которые уже на протяжении нескольких десятилетий имеют высший приоритет", убеждено NASA. Информация с борта аппарата, по мнению его специалистов, будет иметь огромную ценность и с точки зрения подготовки дальнейших пилотируемых полетов за пределы Земли, поскольку позволит прогнозировать "радиационную обстановку, в которой предстоит работать и жить будущим покорителям космоса".
    Зонд назван в честь американского астрофизика Юджина Паркера, которому летом исполнился 91 год. Ученый до сих пор ведет научную деятельность в Университете Чикаго (штат Иллинойс). Паркер стал одним из первых в мире специалистов, занимавшихся исследованиями солнечного ветра. С 1967 года он является членом Национальной академии наук США.
    Предполагается, что зонд Паркера подлетит в семь раз ближе к Солнцу, чем какой-либо другой из космических аппаратов, ранее отправлявшихся человеком.

    On Oct. 29, 2018, at about 1:04 p.m. EDT, Parker Solar Probe became the closest spacecraft to the Sun, breaking the record of 26.55 million miles fr om the Sun's surface set by the Helios 2 in April 1976. But this is just the beginning. Parker Solar Probe -- NASA's mission to touch the Sun -- will get closer still.

    This process is the result of carefully planned orbital mechanics, which will result in 24 passes around the Sun. Parker starts off in an orbit around the Sun which is the same as Earth's - that's where it starts, after all - and gradually moves to a position inside the orbit of Mercury. To do this, the spacecraft must slow down significantly (see Figure 1).

    (https://blogs.nasa.gov/sunspot/wp-content/uploads/sites/289/2018/11/ParkerOrbit.png) (https://blogs.nasa.gov/sunspot/wp-content/uploads/sites/289/2018/11/ParkerOrbit.png)
    Figure 1: Parker Solar Probe orbit in the plane of the solar system. Parker orbit data fr om JHU Applied Physics Lab. Solar system orbit data from JPL/NAIF.
    One of the fundamental principles of orbital dynamics is that if you want to change the periapsis, or point of closest approach, of an elliptical orbit, you get the most bang for your buck if you change speed at the apoapsis, or the point when you're furthest away.

    You can see this principle applied in the case of Parker Solar Probe. Figure 2 below plots Parker's orbital velocity on the y-axis (how fast it's moving relative to the Sun, in kilometers per second, km/s), with time plotted along the x-axis. Parker is represented by the purple curve; Mercury (black curve) and Earth (blue curve) are included for reference. [Click on the graph to see a full-size version.]

    Figure 2: Parker Solar Probe orbit speed plotted with inner solar system planets for comparison. Parker orbit data from JHU Applied Physics Lab. Solar system orbit data from JPL/NAIF.

    The first thing you'll notice is that the purple line is moving up and down quite a bit, indicating changes in its orbital velocity: Parker doesn't travel at a constant speed throughout its orbit, but rather speeds up and slows down at different points.

    The little dots that appear at the spikes and the dips on the curve mark the times when Parker is either furthest from or closest to the Sun on each orbit. The aphelion positions, when Parker is farthest away from the Sun, are marked with red dots: Note that they coincide with the dips in the curve, when Parker has its slowest speed. The perihelion, or close approaches, are marked with green dots, and coincide with the spikes in the graph, wh ere Parker is traveling fastest.

    Over time, you can see that the spikes get taller: Parker's speed at perihelion gets faster and faster. Although the graph doesn't directly show this, these increases in speed correspond to Parker's perihelion moving closer and closer to the Sun: The closer it gets, more of the Sun's gravitational energy gets translated into the spacecraft's energy of motion, increasing its speed. Parker launched from Earth orbit with a speed of about 17 kilometers per second (38,000 miles per hour), slower than the orbital speed of Earth (about 29 kilometers per second or 65,000 miles per hour), enabling it to 'fall' towards the Sun. Accelerating in the Sun's gravity, it reached a speed of over 95 kilometers per second (212,000 miles per hour) at the first closest approach. But looking at the graph, we see that Parker will go faster (and closer) still, its final orbit approaching over 190 kilometers per second (425,000 miles per hour).

    But how does Parker keep getting closer? Getting closer to the Sun doesn't come for free -- each shift in the orbit requires the help of gravitational assists from Venus. Note on the graph above that every time the spacecraft transitions to a higher speed at perihelion, or spike in the curve, there is a prior speed decrease near aphelion, or the dip in the curve, marked on the plot by a thicker red line. For Parker, these speed changes are accomplished with fly-bys of the planet Venus near Parker's aphelion position. Unlike many gravity assists wh ere spacecraft gain energy from sling-shotting around a planet, Parker is losing energy to Venus in order to slow down. By slowing down at aphelion, the orbit's overall size decreases, which in turn increases the spacecraft's speed near the Sun.

    Parker doesn't fly by Venus on every single orbit, it will only go past the planet seven times over the course of seven years - but you can spot the flybys in the graph by noticing a small jag in certain spots. If Parker is accelerating towards the Sun -- i.e., on the upward slopes in the graph, after the dip in a curve -- the flyby appears as a little jag in the orbit, like the one just after October 2019 and October 2021. However, some flybys occur while the spacecraft is outbound from the Sun and decelerating, like the one near July 2020, which is a little less obvious in the plot. Each jag represents Parker moving just a bit slower, just a bit closer to the Sun - on each orbit gathering unprecedented, in situ observations of the star we live with.

    ЦитатаЗонд НАСА передал на Землю первый после сближения с Солнцем сигнал
    07:52 08.11.2018

    ВАШИНГТОН, 8 ноя - РИА Новости. Зонд НАСА Parker Solar Probe успешно перенес сближение с Солнцем и передал первый сигнал на Землю, сообщили в американском космическом ведомстве.

    Parker Solar Probe приблизился к Солнцу на расстояние 24 миллионов километров, став первым из созданных человеком космических кораблей, достигшим такого расстояния от звезды. В среду во второй половине дня специалисты миссии получили первый сигнал от зонда.

    "Полученный сигнал - сигнал А -- является лучшим из всех возможных и свидетельствует, что Parker Solar Probe действует нормально и все его инструменты работают и собирают данные и, если и были незначительные проблемы, они были решены аппаратом автоматически", -- сообщили в НАСА.

    В понедельник аппарат достиг рекордной скорости в 343 тысяч километров в час. "Наряду с достижением максимального приближения к Солнцу, Parker Solar Probe будет повторно бить собственные скоростные рекорды по мере того, как его орбита будет вести его еще ближе к звезде, и он будет двигаться быстрее и быстрее в перигелии (ближайшей к Солнцу точки своей орбиты)", -- отмечают в НАСА.

    Ранее, 29 октября, зонд стал самым близким к Солнцу из созданных когда-либо человеком аппаратов, побив принадлежавший немецко-американскому зонду Hellios 2 рекорд в 26 миллионов миль (41,8 миллиона километров).
    Parker Solar Probe, названный в честь астрофизика Юджина Паркера, стартовал с Земли в августе текущего года. По расчетам создателей, в течение семи лет ему предстоит совершить 24 витка вокруг Солнца.

    Зонд оснащен рядом инструментов, расположенных под массивным тепловым щитом, который должен защитить зонд от "солнечного ожога", в их числе камера, прибор для измерения магнитного и электрического поля в атмосфере Солнца, а также два инструмента для измерения и наблюдения за частицами "солнечного ветра".

    Ранее в НАСА сообщили, что первые полученные им данные будут переданы на Землю в декабре.

    ЦитатаFirst Perihelion: Into the Unknown - Parker Solar Probe

    JHU Applied Physics Laboratory (https://www.youtube.com/channel/UCz4r-ikQdWEj1gG1aFJTy-g)

    Опубликовано: 2 нояб. 2018 г.

    At about 10:28 p.m. EST on Nov. 5, Parker Solar Probe will achieve its first perihelion - its first close approach to the Sun - and will come within 15 million miles of the Sun's surface. During perihelion, the spacecraft will reach a top speed of 213,200 miles per hour relative to the Sun.

    This speed and distance will mark new records for both closest solar approach and top heliocentric speed by a spacecraft.

    At perihelion, Parker Solar Probe will fly through material at about 3.6 million degrees Fahrenheit. The spacecraft will be protected from intense solar radiation by its Thermal Protection System, or heat shield. Parker Solar Probe employs a host of autonomous systems to keep the spacecraft safe without guidance from Earth -- including automatic retraction of the solar panels to regulate their temperature, attitude control using solar limb sensors that ensures all of the instruments remain in the heat shield's shadow, and a sophisticated guidance and control system that keeps the spacecraft pointed correctly.

    For several days around the Nov. 5 perihelion, Parker Solar Probe will be completely out of contact with Earth because of interference from the Sun's overwhelming radio emissions.

    Following perihelion, the mission operations team at the Johns Hopkins Applied Physics Laboratory will await a beacon tone from the spacecraft, which will let them know the status of Parker Solar Probe.

    Parker Solar Probe Reports Good Status After Close Solar Approach

    Parker Solar Probe is alive and well after skimming by the Sun at just 15 million miles from our star's surface. This is far closer than any spacecraft has ever gone -- the previous record was set by Helios B in 1976 and broken by Parker on Oct. 29 (https://www.nasa.gov/feature/goddard/2018/parker-solar-probe-breaks-record-becomes-closest-spacecraft-to-sun) -- and this maneuver has exposed the spacecraft to intense heat and solar radiation in a complex solar wind environment.

    "Parker Solar Probe was designed to take care of itself and its precious payload during this close approach, with no control from us on Earth -- and now we know it succeeded," said Thomas Zurbuchen, associate administrator of NASA's Science Mission Directorate at the agency headquarters in Washington. "Parker is the culmination of six decades of scientific progress. Now, we have realized humanity's first close visit to our star, which will have implications not just here on Earth, but for a deeper understanding of our universe."

    Mission controllers at the Johns Hopkins University Applied Physics Lab received the status beacon from the spacecraft at 4:46 p.m. EST on Nov. 7, 2018. The beacon indicates status "A" -- the best of all four possible status signals, meaning that Parker Solar Probe is operating well with all instruments running and collecting science data and, if there were any minor issues, they were resolved autonomously by the spacecraft.

    At its closest approach on Nov. 5, called perihelion, Parker Solar Probe reached a top speed of 213,200 miles per hour, setting a new record for spacecraft speed. Along with new records for the closest approach to the Sun, Parker Solar Probe will repeatedly break its own speed record as its orbit draws closer to the star and the spacecraft travels faster and faster at perihelion.

    At this distance, the intense sunlight heated the Sun-facing side of Parker Solar Probe's heat shield, called the Thermal Protection System, to about 820 degrees Fahrenheit. This temperature will climb up to 2,500 F as the spacecraft makes closer approaches to the Sun -- but all the while, the spacecraft instruments and systems that are protected by the heat shield are generally kept in the mid-80s F.

    Parker Solar Probe's first solar encounter phase began on Oct. 31, and the spacecraft will continue collecting science data through the end of the solar encounter phase on Nov. 11. It will be several weeks after the end of the solar encounter phase before the science data begins downlinking to Earth.

    Less than three months after its fiery departure fr om Cape Canaveral, NASA's Parker Solar Probe flew within 15 million miles (24 million kilometers) of the sun Monday for the $1.5 billion mission's first close-up solar encounter.

    Flying in an autonomous mode out of contact with ground controllers, the solar probe was on a trajectory that reached its closest point to the sun at 10:28 p.m. EST Monday (0328 GMT Tuesday), according to NASA.

    Parker Solar Probe is circling the sun in an elliptical loop that takes the spacecraft fr om perihelion -- the closest point to the sun which it passed Monday -- to a distant point between the orbits of Venus and Earth. The spacecraft's perihelion Monday reached a position less than half the distance from the sun as Mercury.
    "You're going into an environment that's completely unforgiving," said Andy Driesman, Parker Solar Probe's project manager at the Johns Hopkins University Applied Physics Laboratory, which built and operates the spacecraft. "The temperatures that we are seeing on the spacecraft have not been seen by any other spacecraft ever before. The first perihelion we're going into, we have very minimal contact. All we can get is a tone."

    Ground controllers at APL received a good status tone from Parker at 4:46 p.m. EST Wednesday (2146 GMT), confirming the probe survived the first of at least two dozen journeys close to the sun.

    "Parker Solar Probe was designed to take care of itself and its precious payload during this close approach, with no control from us on Earth -- and now we know it succeeded," said Thomas Zurbuchen, associate administrator of NASA's Science Mission Directorate at the agency headquarters in Washington. "Parker is the culmination of six decades of scientific progress. Now, we have realized humanity's first close visit to our star, which will have implications not just here on Earth, but for a deeper understanding of our universe."

    The spacecraft launched Aug. 12 from Cape Canaveral aboard a United Launch Alliance Delta 4-Heavy rocket, which propelled Parker Solar Probe on a high-speed departure from Earth on the way to Venus. The solar probe flew by Venus on Oct. 3 at a distance of about 1,500 miles (2,400 kilometers), using the planet's gravity like a brake to slow its velocity enough for the sun to pull the spacecraft closer.

    The probe set a record Oct. 29 for the closest approach by a human-made object to the sun, besting a mark se t in April 1976 by the German-American Helios 2 spacecraft at a distance of 26.55 million miles (42.7 million kilometers). On the same day, Parker Solar Probe became the fastest spacecraft relative to the sun, exceeding a heliocentric velocity of 153,454 mph (42.6 miles per second; 68.6 kilometers per second).

    The spacecraft started its first solar encounter phase Oct. 31, and reached the closest point to the sun in its current orbit late Monday, reaching a top speed relative to the sun of 213,200 mph (59.2 miles per second; 95.3 kilometers per second).

    Parker Solar Probe was expected to fly through a region of tenuous material in the sun's outer atmosphere, wh ere temperatures reach 3.6 million degrees Fahrenheit (2 million degrees Celsius), according to a statement released by APL.

    The spacecraft is armored for the extreme temperatures, carrying a 4.5-inch thick (11.4-centimeter) carbon composite heat shield covered in a white ceramic coating. The thermal barrier measures around 8 feet (nearly 2.5 meters wide) on the sun-facing side of the probe, keeping most of the craft's components -- except a few of its sensors and solar arrays -- at a little above room temperature.

    The outside of the heat shield was expected to reach a temperature of around 820 degrees Fahrenheit (437 degrees Celsius) during Monday's closest approach to the sun, significantly lower than the temperature of the surrounding environment. The low-density particles in Parker Solar Probe's orbit do not transfer much of their heat to the spacecraft, allowing it to survive the conditions similar to the way you can put your hand in a kitchen oven -- as long as you don't touch any surfaces.

    "We keep the thermal shield between the spacecraft body and the sun," said Betsy Congdon, lead thermal engineer on Parker Solar Probe at APL. "We have designed the spacecraft to be able to do the right thing, no matter what it sees."

    Scientists programmed Parker Solar Probe's four instrument suites to directly measure the properties of the material in the solar atmosphere, collecting data closer to the sun than ever before. Parker Solar Probe's objectives include studying the origin of the solar wind, a supersonic flow of particles streaming away from the sun in every direction, which drives space weather and influences the entire solar system.

    Named for Eugene Parker, who correctly predicted the existence of the solar wind in 1958, Parker Solar Probe will also investigate why the sun's atmosphere, or corona, is many times hotter than the sun's surface.

    Controllers are unable to fully contact Parker Solar Probe for several days around perihelion due to the interference from solar radio emissions, officials said. Only basic status tones will be transmitted from the spacecraft back to Earth to confirm its health.

    Parker Solar Probe carries autonomous control software to ensure temperature-sensitive components don't get too hot, using inputs from temperature sensors to gauge wh ere the probe should be pointed, and to keep key parts of the spacecraft in the heat shield's shadow. The probe's solar panels can also be pivoted or turned to stay within thermal limits, all without the intervention of ground controllers.

    At the time of Monday's perihelion, Parker Solar Probe was located around 98 million miles (158 million kilometers) from Earth. At that distance, it takes more than 17 minutes for radio signals to make the round-trip journey from the spacecraft to Earth and back.
    The encounter phase ends Nov. 11, and the first science data from Parker Solar Probe's first perihelion will be downlinked to Earth beginning in early December.

    Monday's solar encounter was the first of 24 planned during the probe's mission.

    Six more Venus flybys will spiral Parker Solar Probe ever-closer to the sun, redirecting the craft's trajectory toward its closest encounter with the sun at a distance of 3.83 million miles (6.16 million kilometers) in 2024, roughly 4 percent the distance of the sun from Earth.

    On Nov. 16, Parker Solar Probe reported that all systems are operating well in the first detailed performance and health update sent to Earth by the spacecraft since its first solar encounter.

    At about 6:00 p.m. EST on Friday, Nov. 16, mission controllers at the Johns Hopkins Applied Physics Lab in Laurel, Maryland, received the report from the spacecraft, which also included information about the data collected by the four instrument suites during its first solar encounter. Parker Solar Probe's first solar encounter phase took place Oct. 31 - Nov. 11, culminating in its first close approach to the Sun -- called perihelion -- on Nov. 6 at just 15 million miles from the Sun's surface, the closest any spacecraft has ever come to our star.

    All Parker Solar Probe systems are operating well and as designed. The solid state recorder on the spacecraft indicated that, as planned, the four instrument suites had recorded a significant amount of data, which is scheduled to be downloaded to Earth via the Deep Space Network over several weeks starting Dec. 7. In addition to helping scientists begin to explore fundamental questions about the physics of our star, the data from this initial perihelion -- collected closer to the Sun than any before -- will help instrument teams calibrate Parker Solar Probe's instruments and plan future observations.
    "The team is extremely proud to confirm that we have a healthy spacecraft following perihelion," said APL's Nick Pinkine, mission operations manager for Parker Solar Probe. "This is a big milestone, and we're looking forward to some amazing science data coming down in a few weeks."

    During the 11-day solar encounter, the spacecraft executed only one autonomous momentum dump - a procedure in which small thrusters are used to adjust the speed of Parker's reaction wheels. The rate of spin of the wheels is adjusted to maintain the desired orientation of the spacecraft relative to the Sun. Momentum dumps are expected during solar encounters, as the wheels spin up to counter increasing torque from the gravitational effects of the solar environment. Executing only one dump indicates that the spacecraft is well balanced, minimizing the need for these dumps during future solar encounters, which will save propellant.
    Parker Solar Probe's second perihelion will occur on April 4, 2019. During the seven-year mission, the spacecraft will perform a total of 24 perihelia, with the last three bringing the spacecraft to less than 4 million miles from the Sun's surface.

    ЦитатаAll Systems Go As Parker Solar Probe Begins Second Sun Orbit

    Posted on 01/22/2019 09:15:00

    On Jan. 19, 2019, just 161 days after its launch from Cape Canaveral Air Force Station in Florida, NASA's Parker Solar Probe completed its first orbit of the Sun, reaching the point in its orbit farthest from our star, called aphelion. The spacecraft has now begun the second of 24 planned orbits, on track for its second perihelion, or closest approach to the Sun, on April 4, 2019.

    Parker Solar Probe entered full operational status (known as Phase E) on January 1, with all systems online and operating as designed. The spacecraft has been delivering data from its instruments to Earth via the Deep Space Network, and to date more than 17 gigabits of science data has been downloaded. The full dataset from the first orbit will be downloaded by April.

    "It's been an illuminating and fascinating first orbit," said Parker Solar Probe Project Manager Andy Driesman, of the Johns Hopkins University Applied Physics Laboratory. "We've learned a lot about how the spacecraft operates and reacts to the solar environment, and I'm proud to say the team's projections have been very accurate." APL designed, built, and manages the mission for NASA.

    "We've always said that we don't know what to expect until we look at the data," said Project Scientist Nour Raouafi, also of APL. "The data we have received hints at many new things that we've not seen before and at potential new discoveries. Parker Solar Probe is delivering on the mission's promise of revealing the mysteries of our Sun."

    The Parker Solar Probe team is not only focused on analyzing the science data but also preparing for the second solar encounter, which will take place in about two months.

    In preparation for that next encounter, the spacecraft's solid state recorder is being emptied of files that have already been delivered to Earth. In addition, the spacecraft is receiving upd ated positional and navigation information (called ephemeris) and is being loaded with a new automated command sequence, which contains about one month's worth of instructions.

    Like the mission's first perihelion in November 2018, Parker Solar Probe's second perihelion in April will bring the spacecraft to a distance of about 15 million miles from the Sun - just over half the previous close solar approach record of about 27 million miles se t by Helios 2 in 1976.

    The spacecraft's four instrument suites will help scientists begin to answer outstanding questions about the Sun's fundamental physics -- including how particles and solar material are accelerated out into space at such high speeds and why the Sun's atmosphere, the corona, is so much hotter than the surface below.

    On March 30, 2019, Parker Solar Probe begins the second solar encounter phase of its mission, culminating in its closest approach to the Sun, called perihelion, on April 4.

    During this solar encounter phase, which lasts until April 10, the spacecraft's four suites of science instruments (https://www.nasa.gov/content/goddard/parker-solar-probe-instruments) are fully operational and storing science data collected from within the Sun's corona. As designed, Parker Solar Probe will be out of contact with Earth for several days during the solar encounter. This allows the spacecraft to prioritize keeping its heat shield, called the Thermal Protection System (https://www.nasa.gov/feature/goddard/2018/traveling-to-the-sun-why-won-t-parker-solar-probe-melt), oriented towards the Sun, rather than pointing its transmitter towards Earth. Science data from this second solar encounter phase will downlink to Earth over several weeks later in spring 2019.

    Like the mission's first orbit, Parker Solar Probe will reach a perihelion of about 15 million miles from the Sun's surface -- meeting its own record for closest-ever approach to the Sun, a little more than half the previous record distance of about 27 million miles set by Helios 2 in 1976. The spacecraft's top speed of about 213,200 miles per hour is also the same as the first solar encounter of the mission. In December 2019, Parker Solar Probe will perform the second of seven Venus gravity assists (https://www.nasa.gov/feature/goddard/2018/parker-solar-probe-changed-the-game-before-it-even-launched/) of its mission, setting up the trajectory that will carry the spacecraft closer to the Sun and to a higher top speed.

    Солнечный зонд «Паркер» начал второе тесное сближение с Солнцем: 4 апреля он пролетит на минимальном на данный момент расстоянии от звезды (около 24 миллионов километров). Это позволит зонду получить новые данные о солнечном ветре и короне Солнца, сообщается (http://parkersolarprobe.jhuapl.edu/News-Center/Show-Article.php?articleID=120) на сайте миссии.
    Запуск зонда «Паркер» (https://en.wikipedia.org/wiki/Parker_Solar_Probe) в космос состоялся (https://nplus1.ru/news/2018/08/12/launch) 13 августа 2018 года. Цель миссии -- измерение основных характеристик солнечного ветра (потока высокоэнергетичных заряженных частиц, непрерывно испускаемых Солнцем) и солнечной атмосферы вдоль своей траектории, а также изучение электромагнитных полей вблизи Солнца и процессов, идущих в его внешних слоях. От сильного нагрева и потоков заряженных частиц и излучения от звезды аппарат защищают система охлаждения и теплозащитный щит, под которым укрываются все научные приборы. По плану процесс сближения со звездой продлится семь лет: с каждой новой орбитой (всего их 24) аппарат будет все ближе подходить к светилу.
    В ноябре 2018 года «Паркер» прошел свой первый перигелий (https://ru.wikipedia.org/wiki/%D0%9F%D0%B5%D1%80%D0%B8%D0%B3%D0%B5%D0%BB%D0%B8%D0%B9), побив рекорд аппарата Helios-B (https://en.wikipedia.org/wiki/Helios_(spacecraft)#Helios-B), который подлетал к звезде на 43,5 миллиона километров в 1976 году. 30 марта 2019 года зонд начал новую фазу сближения со звездой в рамках полета по второй научной орбите вокруг Солнца, а 4 апреля должен пролететь на расстоянии около 24 миллионов километров от звезды, двигаясь со скоростью 343 тысячи километров в час. Собирать научные данные зонд будет в полностью автономном режиме. Фаза сближения окончится 10 ноября, после чего начнется передача данных на Землю.

    В декабре 2019 года зонд совершит второй гравитационный маневр вблизи Венеры, а самое тесное сближение с Солнцем запланировано на середину декабря 2024 года, когда «Паркер» окажется на расстоянии около 9-10 солнечных радиусов (около шести миллионов километров) от звезды. Это в семь раз ближе, чем перигелий орбиты Меркурия: еще ни один космический аппарат не подбирался настолько близко к Солнцу.

    Parker Solar Probe has successfully completed its second close approach to the Sun, called perihelion, and is now entering the outbound phase of its second solar orbit. At 6:40 p.m. EDT on April 4, 2019, the spacecraft passed within 15 million miles of our star, tying its distance record (https://www.nasa.gov/feature/goddard/2018/parker-solar-probe-breaks-record-becomes-closest-spacecraft-to-sun/) as the closest spacecraft ever to the Sun; Parker Solar Probe was traveling at 213,200 miles per hour during this perihelion.

    The Parker Solar Probe mission team at the Johns Hopkins Applied Physics Laboratory, or APL, in Laurel, Maryland scheduled a contact with the spacecraft via the Deep Space Network for four hours around the perihelion and monitored the health of the spacecraft throughout this critical part of the encounter. Parker Solar Probe sent back beacon status "A" throughout its second perihelion, indicating that the spacecraft is operating well and all instruments are collecting science data.

    "The spacecraft is performing as designed, and it was great to be able to track it during this entire perihelion," said Nickalaus Pinkine, Parker Solar Probe mission operations manager at APL.(https://blogs.nasa.gov/parkersolarprobe/wp-content/uploads/sites/274/2019/04/SolarSwingBy2.gif) (https://svs.gsfc.nasa.gov/12729)
    "We're looking forward to getting the science data down from this encounter in the coming weeks so the science teams can continue to explore the mysteries of the corona and the Sun."

    Parker Solar Probe began this solar encounter on March 30, and it will conclude on April 10. The solar encounter phase is roughly defined as when the spacecraft is within 0.25 AU -- or 23,250,000 miles -- of the Sun. One AU, or astronomical unit, is about 93 million miles, the average distance from the Sun to Earth.

    As NASA's Parker Solar Probe approaches its third encounter with the Sun, mission scientists are hard at work poring over data from the spacecraft's first two flybys of our star -- and thanks to excellent performance by the spacecraft and the mission operations team, they're about to get something extra.

    On May 6, 2019, just over a month after Parker Solar Probe completed its second solar encounter, the final transmission of 22 gigabytes of planned science data -- collected during the first two encounters -- was downlinked by the mission team at the Johns Hopkins Applied Physics Laboratory, or APL, in Laurel, Maryland.

    This 22 GB is 50% more data than the team had estimated would be downlinked by this point in the mission -- all because the spacecraft's telecommunications system is performing better than pre-launch estimates. After characterizing the spacecraft's operations during the commissioning phase, which began soon after launch, the Parker mission team determined that the telecom system could effectively deliver more downlink opportunities, helping the team maximize the download of science data.

    The team has capitalized on the higher downlink rate, instructing Parker Solar Probe to record and send back extra science data gathered during its second solar encounter. This additional 25 GB of science data will be downlinked to Earth between July 24 and Aug. 15.

    In this image from the Deep Space Network Now (https://eyes.nasa.gov/dsn/dsn.html) site, Parker Solar Probe is shown connecting with a carrier wave to antennas 25 and 55 on Aug. 1, 2019. Parker Solar Probe is identified as SPP by DSN; the mission, formerly Solar Probe Plus, was renamed for solar scientist Eugene Parker in 2017.

    "All of the expected science data collected through the first and second encounters is now on the ground," said Nickalaus Pinkine, Parker Solar Probe mission operations manager at APL. "As we learned more about operating in this environment and these orbits, the team did a great job of increasing data downloads of the information gathered by the spacecraft's amazing instruments."

    There are four instrument suites (https://www.nasa.gov/content/goddard/parker-solar-probe-instruments) on Parker, gathering data on particles, waves, and fields related to the Sun's corona and the solar environment. Scientists use this information -- gathered closer to the Sun than any previous measurements -- along with data from other satellites and scientific models to expand on what we currently know about the Sun and how it behaves. Data collected during the first two perihelia will be made available to the public later this year.

    Parker Solar Probe continues on its record-breaking exploration of the Sun with its third solar encounter beginning Aug. 27, 2019; the spacecraft's third perihelion will occur on Sept. 1.

    After Parker Solar Probe's successful first year in space, the mission team has decided to extend science observations as the spacecraft approaches its third solar encounter.

    Parker Solar Probe turned on its four instrument suites (https://www.nasa.gov/content/goddard/parker-solar-probe-instruments) on Aug. 16, 2019 -- earlier than during its previous two solar encounters, extending the observation period from 11 days to about 35 days.

    During the spacecraft's first two solar encounters, the science instruments were turned on when Parker was about 0.25 AU from the Sun and powered off again at the same distance on the outbound side of the orbit. (One AU, or astronomical unit, is about 93 million miles, the average distance between the Sun and Earth.) For this third solar encounter, the mission team turned on the instruments when the spacecraft was around 0.45 AU from the Sun on the inbound side of its orbit and will turn them off when the spacecraft is about 0.5 AU from the Sun on the outbound side.

    "We've seen very intriguing phenomena below 0.25 AU, and are confident we will see interesting things all the way out to 0.5 AU," said Nour Raouafi, Parker Solar Probe project scientist at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. "We cannot wait to see how this extended campaign data will compare to our previous data collected during the shorter periods and to the data from previous missions, such as Helios."

    The extended observation time before and after Parker Solar Probe's perihelion -- its closest approach to the Sun during a given orbit -- will let scientists capture the evolution of the solar wind over greater distances as it travels away from the Sun. They also hope the additional data will yield more insight into the energetic particles surrounding the Sun, the corona and the overall solar environment.

    The data gathered during this period will start downlinking immediately at the end of the extended campaign. The data from the first two encounters will be released to the public in 2019. Parker Solar Probe's third perihelion will occur on Sept. 1.

    At just before 1:50 p.m. EDT on Sept. 1, 2019, NASA's Parker Solar Probe completed its third close approach of the Sun, called perihelion. At the time of perihelion, the spacecraft was about 15 million miles from the Sun's surface, traveling at more than 213,200 miles per hour.

    Mission controllers at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, received a green "A" beacon from the spacecraft soon after perihelion, meaning all systems were performing as designed and that the spacecraft was in good health.

    This third encounter, which was at approximately the same distance from the Sun and speed as the first two, differs in that the spacecraft's four instrument suites have been on and gathering data for a longer period than other perihelia.

    For this third solar encounter, the mission team turned on the instruments when the spacecraft was around 0.45 astronomical units from the Sun on the inbound side of its orbit. (One astronomical unit, or AU, is about 93 million miles, the average distance between the Sun and Earth.) The instruments will be turned off when Parker Solar Probe is about 0.5 AU from the Sun on the outbound side, which will occur on about Sept. 20. For the prior two perihelia, the instruments were on from 0.25 AU prior to and after completing the close approach.

    Data from the Wide-field Imager for Solar Probe (WISPR) instrument on board Parker Solar Probe captured during the spacecraft's first solar encounter in November 2018.

    The released encounter data encompasses measurements made during the first two solar encounters, spanning the time between Oct. 31 and Nov. 12, 2018, and March 30 and April 19, 2019, when the spacecraft was within 0.25 AU of the Sun, as well as data collected at farther distances. One AU, or astronomical unit, is about 93 million miles, the average distance between the Sun and Earth.

    Science teams led by principal investigators from partner institutions have been busy poring over the wealth of information collected by Parker Solar Probe in preparation for the mission's first science results, to be released later this year. The four instrument suites onboard - FIELDS, ISʘIS, SWEAP, and WISPR (https://www.nasa.gov/content/goddard/parker-solar-probe-instruments) - have been observing the characteristics of the solar wind (fields, waves, flows, and particles) in the immediate environment surrounding the Sun, called the corona.

    "Parker Solar Probe is crossing new frontiers of space exploration, giving us so much new information about the Sun," said Parker Solar Probe Project Scientist Nour E. Raouafi, from the Johns Hopkins Applied Physics Laboratory, or APL, in Laurel, Maryland, which manages the mission for NASA. "Releasing this data to the public will allow them not only to contribute to the success of the mission along with the scientific community, but also to raise the opportunity for new discoveries to the next level."

    With three of 24 planned solar orbits under its belt, Parker Solar Probe will continue to get closer to the Sun in the coming years, eventually swooping to within 4 million miles of the Sun's surface, facing heat and radiation like no spacecraft before it. The mission seeks to provide new data on solar activity and how the solar corona works, which contributes significantly to our ability to forecast major space weather events that impact life on Earth. The mission launched in 2018 and is slated to perform its primary science mission until 2025.

    NASA's Parker Solar Probe mission has returned unprecedented data from near the Sun, culminating in new discoveries published on Dec. 4, 2019, in the journal Nature. Among the findings are new understandings of how the Sun's constant outflow of material, the solar wind, behaves. Seen near Earth -- wh ere it can interact with our planet's natural magnetic field and cause space weather effects that interfere with technology -- the solar wind appears to be a relatively uniform flow of plasma. But Parker Solar Probe's observations reveal a complicated, active system not seen from Earth.

    Благодаря зонду Parker Solar Probe внутри солнечного ветра нашли "американские горки"
    Астрономы обнаружили и другие аномалии магнитного поля светила

    ТАСС, 5 декабря. Астрономы проанализировали первые данные, которые собрал зонд Parker Solar Probe в ходе первых двух сближений с Солнцем на максимально близкие расстояния. Эти замеры раскрыли необычные особенности магнитного поля внутри солнечного ветра и другие странности в поведении светила, которые нельзя увидеть с орбиты Земли. Ученые пишут об этом в статьях, которые опубликовал научный журнал Nature (1 (https://www.nature.com/articles/s41586-019-1813-z), 2 (https://www.nature.com/articles/s41586-019-1818-7), 3 (https://www.nature.com/articles/s41586-019-1811-1), 4 (https://www.nature.com/articles/s41586-019-1807-x)).

    "Первые сближения с Солнцем были просто потрясающими. Мы смогли изучить магнитную структуру короны и подтвердили, что солнечный ветер исходит из так называемых корональных дыр, открыли загадочные плазменные "американские горки", предположительно связанные с процессом формирования солнечного ветра, а также увидели очаги нестабильности внутри этого потока газа. Вдобавок, нас удивила сила "пылевых бурь" в непосредственной близости от Солнца", - прокомментировал результаты один из авторов работы, астроном из Калифорнийского университета в Беркли (США) Стюарт Бейл.

    Зонд Parker Solar Probe (PSP) стартовал в августе прошлого года. Цель миссии - решить одну из самых амбициозных задач в истории астрономии и космонавтики - сближения с Солнцем на минимально возможное расстояние, которое составит примерно шесть миллионов километров. В конечном итоге, работа PSP завершится погружением в раскаленную атмосферу светила, что произойдет, как ожидают ученые, в середине следующего десятилетия.

    По текущим планам NASA, этот аппарат пролетит через корону Солнца 24 раза, постепенно сближаясь с поверхностью светила. Parker Solar Probe оборудован тепловым экраном из специального углепластикового материала толщиной в 11 сантиметров и шириной в несколько метров, который защитит его от уничтожения в ходе этих встреч со светилом.

    Как надеются ученые, данные, которые уже собрал и продолжает получать PSP, помогут астрофизикам понять, почему корона Солнца на несколько порядков горячее, чем его поверхность. Полноценного объяснения этого феномена пока не существует. Многие астрономы предполагают, что атмосферу Солнца разогревают мощные выбросы плазмы или же микровспышки, которые постоянно возникают на его поверхности. Однако однозначных свидетельств, которые подтвердили бы эти предположения, астрономы пока не нашли.

    Солнечные "американские горки"

    Первые данные такого рода PSP получил в ноябре прошлого года, когда он впервые пролетел через окрестности короны Солнца. За последующие месяцы он успел еще два раза сблизиться со светилом, получая новую информацию по устройству атмосферы звезды и свойствам солнечного ветра. Специалисты NASA и ведущие астрономы мира только недавно завершили обработку и интерпретацию замеров, которые четыре инструмента зонда провели во время двух первых пролетов.

    Как отметил Бейл, эти замеры принесли массу неожиданных открытий несмотря на то, что они были проведены с расстояния в 24 миллиона километров от поверхности Солнца. В частности, ученые выяснили, что светило вырабатывает солнечный ветер не постоянно, а своеобразными порциями, и что внутри него существуют странные структуры, которые астрономы NASA окрестили "американскими горками". Их появление сопровождалось усилением ветра и выделением больших количеств энергии.

    Как предполагают ученые, эти структуры представляют собой S-образные изгибы линий магнитного поля, которые периодически появлялись внутри плазмы солнечного ветра и исчезали через несколько часов. По мнению Бейла, их появление связано с пока неизвестными выбросами плазмы на поверхности Солнца, и они могут играть ключевую роль в разогреве короны светила и формировании солнечного ветра.

    На этом странности не закончились - замеры инструментов PSP показывают, что светило "закручивает" солнечный ветер гораздо сильнее, чем показывали компьютерные модели и наблюдения с Земли. Кроме того, в его ближайших окрестностях, скорее всего, присутствует значительно меньше пыли, чем ожидали увидеть астрономы.

    При этом ее скопления оказались гораздо более плотными и "агрессивными" в тех регионах околосолнечного пространства, где есть значительные количества перемолотой материи комет и астероидов. В частности, во время одного из пролетов PSP пылинка попала в один из 90 объективов инструмента WISPR и пробила его. Его потеря, как подчеркнули в NASA, не скажется на качестве работы WISPR и решении научных задач миссии.

    Все эти открытия, как ожидают ученые, теоретикам придется объяснять заново. Кроме того, для этого нужны будут еще и новые наблюдения, которые PSP проведет уже в начале 2020 года. С другой стороны, уже собранные данные, по мнению Бейла и других участников миссии, значительно сузят перечень теорий, которые описывают процесс формирования солнечного ветра. Это поможет астрономам точнее предсказывать космическую погоду уже в ближайшем будущем.

    Miles Hatfield (https://blogs.nasa.gov/parkersolarprobe/author/mshatfie/)

    After nearly 17 months in space culminating with the release of new science data (https://www.nasa.gov/feature/goddard/2019/nasas-parker-solar-probe-sheds-new-light-on-the-sun/), Parker Solar Probe is right on course for its second Venus gravity assist maneuver. This flyby will set the spacecraft up for its fourth perihelion of the Sun, during which it will set records for spacecraft speed and closest solar distance, while continuing to gather groundbreaking data from within the Sun's corona to help scientists make new discoveries.

    (https://blogs.nasa.gov/parkersolarprobe/wp-content/uploads/sites/274/2019/12/VGA-diagram2-1.png) (https://blogs.nasa.gov/parkersolarprobe/wp-content/uploads/sites/274/2019/12/VGA-diagram2-1.png)
    Diagram of the locations and dates of Parker Solar Probe's first four Venus gravity assists. The upcoming Venus gravity assist on Dec. 26, 2019, will be the second such maneuver of the mission.

    On Dec. 26, at 1:14 p.m. EST, Parker Solar Probe will perform its second Venus flyby, during which the spacecraft will fly within 1,870 miles of Venus, using the planet to slow itself down and adjust its trajectory for an optimal path toward the Sun. This move allows Parker Solar Probe to precisely position itself for a fourth orbit around Earth's star--with its next close approach, or perihelion, on January 29, 2020--when it will break its own speed and distance records (https://www.nasa.gov/feature/goddard/2018/parker-solar-probe-breaks-record-becomes-closest-spacecraft-to-sun/), flying within 11.6 million miles of the Sun's surface, 20 percent closer than its first three perihelia.

    "These gravity assist maneuvers create the enormous orbit reduction required to get Parker Solar Probe close to the Sun," said Yanping Guo, mission and navigation design manager for Parker Solar Probe at the Johns Hopkins Applied Physics Lab (APL) in Laurel, Maryland. "The seven Venus flybys are connected in a unique sequence, and each of the flybys is chosen not only to make the necessary orbit reductions, but also to hit the subsequent flybys."

    To prepare for this planetary maneuver, the Parker Solar Probe mission operations team at APL performed a small trajectory correction maneuver (TCM) on the spacecraft on Dec. 8. This TCM very accurately lined up the spacecraft for the rendezvous with Venus. After the flyby, the team will perform another TCM to fine-tune Parker Solar Probe's final approach for its fourth perihelion.

    The spacecraft will complete five more of these critical Venus flybys in the coming years in order to gradually pull it closer to the Sun.

    ЦитатаСолнечный зонд Паркер готовится для второго маневра у Венеры
    Спустя почти 17 месяцев в космосе, кульминацией которого стали публикации новых научных данных, Parker Solar Probe начинает свой второй маневр у Венеры. Этот маневр выведет космический аппарат к четвертому перигелию у Солнца, во время которого он установит рекорд скорости космического аппарата и ближайшего расстояния до солнца, продолжая при этом собирать новаторские данные о солнечной короне, чтобы помочь ученым сделать новые открытия.
    26 декабря в 21:14 по московскому времени, Солнечный зонд Parker выполнит свой второй маневр у Венеры, во время которого космический аппарат пролетит в пределах 3000 километров от Венеры, используя планету, чтобы замедлить себя и скорректировать свою траекторию для оптимального пути к Солнцу. Это позволит солнечному зонду Parker точно спозиционировать себя для четвертого пролета у Солнца - с последующим приближением или перигелием, 29 января 2020 года. В этот день он побьет свои собственные рекорды скорости и расстояния, пролетев в пределах 18,7 миллионов километров от поверхности Солнца, что на 20 процентов ближе, чем его первые три перигелия.
    «Эти гравитационные маневры помогают создать огромное снижение орбиты, необходимое для того, чтобы приблизить зонд Parker к Солнцу», - сказал Янпинг Го (Yanping Guo), менеджер по проектированию и навигации Parker Solar Probe в Лаборатории прикладной физики Джонса Хопкинса (APL) в Лореле, штат Мэриленд. «Семь пролетов у Венеры соединены в уникальной последовательности, и каждый из них выбран не только для того, чтобы сделать необходимые сокращения орбиты, но и для того, чтобы улучшить последующие маневры».
    Чтобы подготовиться к этому маневру, оперативная группа миссии Parker Solar Probe в APL выполнила небольшой маневр коррекции траектории (TCM) на космическом корабле 8 декабря. Этот маневр очень точно выстроил космический корабль для встречи с Венерой. После облета команда выполнит еще один маневр, чтобы точно настроить окончательный подход зонда к его четвертому перигелию.
    В ближайшие годы космический аппарат завершит еще пять таких критических пролетов у Венеры, чтобы постепенно приблизить ее к Солнцу.
    "её", естественно, не Венеру, а собственную орбиту :)

    On Dec. 26, Parker Solar Probe successfully completed its second flyby of Venus. The spacecraft used Venus to slow itself down, approaching the planet at a distance of about 1,870 miles from Venus's surface during the second gravity assist of the mission. This gravity assist maneuver adjusted Parker Solar Probe's trajectory to set it up for its fourth orbit around the Sun, or perihelion, which will occur on January 29, 2020. The flight operations team will use the data collected during the recent flyby to make adjustments for the remaining five Venus gravity assists which will occur over the course of the seven-year mission.

    ЦитатаЗонд Parker Solar Probe совершил гравитационный маневр на орбите Венеры
    ТАСС, 27 декабря. Межпланетная станция NASA Parker Solar Probe сблизилась с Венерой, пролетев на расстоянии в три тысячи километров от поверхности планеты, и успешно использовала ее притяжение для того, чтобы скорректировать курс на сближение с Солнцем. Оно состоится 29 января, пишет пресс-служба NASA.
    "Этот гравитационный маневр снизил скорость движения и изменил траекторию полета Parker Solar Probe таким образом, что он в четвертый раз подойдет к Солнцу на рекордно малое расстояние. Данные, собранные в ходе этого сближения с Венерой, помогут скорректировать остальные пять гравитационных маневров, которые PSP проведет за семь лет работы на орбите", - пишет пресс-служба.
    Миссия Parker Solar Probe (PSP) стартовала в августе прошлого года. Ее цель - сблизиться с Солнцем на минимально возможное расстояние, примерно шесть миллионов километров. Завершив свою работу, PSP должен погрузиться в раскаленную атмосферу светила, что произойдет, как ожидают ученые, в середине следующего десятилетия.
    Согласно текущим планам NASA, этот аппарат должен пролететь через корону светила 24 раза, постепенно сближаясь с поверхностью Солнца. Не сгореть ему поможет специальный тепловой экран из специального углепластикового материала толщиной в 11 сантиметров и шириной в несколько метров. Во время последнего сближения, когда Parker Solar Probe должен сгореть в атмосфере Солнца, зонд будет двигаться на скорости 690 тысяч километров в час.
    Как надеются ученые, данные, которые уже собрал и продолжает получать PSP, помогут астрофизикам понять, почему корона Солнца на несколько порядков горячее, чем его поверхность. Пока полноценного объяснения не существует. С момента запуска PSP уже три раза пролетел через окрестности Солнца, открыв несколько новых феноменов в работе его атмосферы и недр, о существовании которых ученые раньше не подозревали.

    Наоборот.
    Аппарат уменьшил полуось своей гелиоцентрической орбиты, а значит и полную энергию,
    а, следовательно, Венера должна увеличить - т.е. удалиться немножко от Солнца.

    There's a wind that emanates from the Sun. It blows not like a soft whistle but like a hurricane's scream. Made of electrons, protons and heavier ions, the solar wind courses through the solar system at roughly 1 million mph (1.6 million kph), barreling over everything in its path. Yet through the wind's roar, NASA's Parker Solar Probe hears the small chirps, squeaks and rustles that hint at the origin of this mysterious and ever-present wind. The spacecraft's FIELDS instrument can eavesdrop on the electric and magnetic fluctuations caused by plasma waves. The Parker Solar Probe it can "hear" when the waves and particles interact with one another, recording frequency and amplitude information about these plasma waves that scientists could then play as sound waves. And it results in some striking sounds.

    NASA's Parker Solar Probe began its fourth solar encounter today at 9:00 a.m. EST, at a distance of about 23.3 million miles from the Sun's surface. It will reach perihelion, its closest distance to our star, during this orbit on Jan. 29 at about 4:30 a.m. EST.

    Parker Solar Probe began its fourth solar encounter on Jan. 23, 2020. Track the spacecraft's speed and position online. (http://parkersolarprobe.jhuapl.edu/The-Mission/index.php#Where-Is-PSP)

    The fourth perihelion will send the spacecraft within 11.6 million miles of the Sun, closer than its first three perihelia, which were at about 15 million miles from the Sun. The spacecraft's four instrument suites will acquire data in this new environment, sampling this previously unexplored region around the Sun and potentially revealing new information about the solar wind and atmosphere.

    Parker Solar Probe's first three orbits of the Sun were all approximately the same distance from our star. Following the mission's second Venus flyby on Dec. 26, 2019, and after one trajectory correction maneuver on Jan. 10, the spacecraft will set new records for distance from the Sun and fastest human-made object during its fourth perihelion; both records are currently held (https://www.nasa.gov/feature/goddard/2018/parker-solar-probe-breaks-record-becomes-closest-spacecraft-to-sun) by Parker Solar Probe.

    At 4:37 a.m. EST on Jan. 29, 2020, NASA's Parker Solar Probe broke speed and distance records as it completed its fourth close approach of the Sun. The spacecraft traveled 11.6 million miles from the Sun's surface at perihelion, reaching a speed of 244,225 miles per hour. These achievements topple Parker Solar Probe's own previous records for closest spacecraft to the Sun -- previously about 15 million miles from the Sun's surface -- and fastest human-made object, before roughly 213,200 miles per hour.

    Parker Solar Probe will continue to fly ever closer to the Sun on its seven-year journey, exploring regions of space never visited before and providing scientists with key measurements to help unveil the mysteries of the solar corona and wind.

    As with most of Parker Solar Probe's close approaches, the spacecraft is out of contact with Earth for several days around perihelion.

    NASA's Parker Solar Probe is healthy and operating as designed following its fourth close approach to the Sun, called perihelion, on Jan. 29.

    Mission controllers at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, received a "status A" beacon from the spacecraft at 5:20 a.m. EST on Feb. 1. Status A is the best of four possible status signals, and indicates that the spacecraft is operating nominally and the instrument suites are collecting science data. This status also indicates that any minor issues that may have occurred were identified and resolved by Parker Solar Probe's onboard autonomy and fault management systems.

    During this perihelion, Parker Solar Probe broke its own records for speed and proximity to the Sun for a human-made object. The spacecraft reached a speed of 244,255 miles per hour (about 393,044 kilometers per hour) as it whipped around the Sun at a distance of 11.6 million miles (about 18.6 million kilometers).

    Parker Solar Probe's heat shield, called the Thermal Protection System, or TPS, reached new record temperatures as well. At this distance from the Sun, computer modeling estimates show that the Sun-facing side of the TPS experienced a blazing 1,134 degrees Fahrenheit (612 degrees C), about 300 degrees hotter than encountered on the spacecraft's previous three perihelia. The spacecraft and instruments behind this protective heat shield remained at a temperature of about 85 F (30 C). During the spacecraft's closest three perihelia in 2024-25, the TPS will see temperatures around 2,500 F (1,370 C).

    As the mission team learns more about operations and conditions in this region of space, they have increased the amount of time the instruments are on and gathering data. Parker Solar Probe's fourth solar encounter phase began on Jan. 23, and the spacecraft will continue to acquire science data through Feb. 29, beyond the originally-planned end of the solar encounter phase on Feb. 4. This solar encounter data will be downlinked to Earth beginning in March.

    NASA's Parker Solar Probe team released a second collection of science data to the public on April 14, 2020. The release includes science data from all four of Parker Solar Probe's instrument suites, spanning the mission's third orbit around the Sun, which began on June 18, 2019 and completed on November 15, 2019. Also included are high-resolution measurements from the FIELDS and SWEAP instruments.

    The data files and graphical displays can be accessed through NASA's Space Physics Data Facility (SPDF) (https://spdf.gsfc.nasa.gov/) and Solar Data Analysis Center (SDAC) (https://umbra.nascom.nasa.gov/index.html/), the APL Parker Solar Probe Gateway (http://sppgway.jhuapl.edu/), and the Science Operation Centers of the four science investigation teams (the University of California, Berkeley (http://fields.ssl.berkeley.edu/); Princeton University (https://spacephysics.princeton.edu/missions-instruments/isois); Harvard-Smithsonian Center for Astrophysics (http://sweap.cfa.harvard.edu/); and Naval Research Laboratory (https://wispr.nrl.navy.mil/).) Data from Parker Solar Probe's first two orbits is also available.

    New findings from the mission's first record-setting year in space were released in the Dec. 12, 2019 issue of the journal Nature (https://www.nature.com/nature/volumes/576/issues/7786) and a special issue of the Astrophysical Journal Supplement Series (https://iopscience.iop.org/journal/0067-0049/page/Early_Results_from_Parker_Solar_Probe). Parker Solar Probe's observations reveal a complicated, active system near the Sun's surface, including a notable phenomenon called switchbacks, which are traveling disturbances in the solar wind that cause the magnetic field to bend back on itself. These switchbacks may be a major source for the heating and acceleration of the solar wind plasma.

    To date, Parker Solar Probe has completed four of its planned 24 orbits around the Sun. It will eventually travel within 4 million miles of the Sun's surface, facing extreme heat and radiation. The mission seeks to provide new data on solar activity and how the solar corona works, which contributes significantly to our ability to forecast major space weather events that impact life on Earth. Parker Solar Probe launched in 2018 and will conduct its primary science mission until 2025.

    On May 9, 2020, NASA's Parker Solar Probe began its longest observation campaign to date. The spacecraft, which has already completed four progressively closer orbits around the Sun, activated its instruments at a distance of 62.5 million miles from the Sun's surface, some 39 million miles farther from the Sun than a typical solar encounter. The four instrument suites will continue to collect data through June 28, markedly longer than the mission's standard 11-day encounters.

    The nearly two-month campaign is spurred by Parker Solar Probe's earlier observations, which revealed significant rotation of the solar wind and solar wind phenomena occurring much farther from the Sun than previously thought. The earlier activation of the science instruments allows the team to cover a larger range in order to trace the evolution of the solar wind as it moves away from the Sun.

    "We have a real opportunity here to see what's going on in these regions further from the Sun's corona," said Nour Raouafi, Parker Solar Probe project scientist at the Johns Hopkins Applied Physics Laboratory. "While our primary goal is to understand the mysteries at the Sun's corona and the 'young' solar wind closer to the Sun, there is evidence indicating very interesting physics to explore earlier in the orbit and link that to what occurs near the Sun. We have the capability to gather this data and see what it yields."

    The spacecraft will reach its closest point to the Sun for this orbit, called perihelion, on June 7. At perihelion, Parker Solar Probe will be about 11.6 million miles from the Sun's surface, matching its own record for closest human-made object to the Sun set during its fourth orbit (https://blogs.nasa.gov/parkersolarprobe/2020/02/01/parker-solar-probe-reports-successful-record-setting-fourth-close-encounter-of-the-sun/) on Jan. 29.

    After this solar encounter, the spacecraft will swoop by Venus for its first outbound flyby of the planet. This is when Parker Solar Probe will perform its third Venus gravity assist, which will allow the spacecraft to shed some of its orbital energy and get much closer to the Sun on the following orbit. Flying at an altitude of approximately 516 miles above Venus' surface -- much lower than the previous two flybys but still well above Venus' atmosphere -- Parker Solar Probe will also witness a brief 11-minute solar eclipse during the maneuver. All four instrument suites will be on and collecting data about the near-Venus environment and the planet's night side during the flyby.

    Data from this fifth observation campaign will be downlinked to Earth between late June and mid-August 2020, and will be released to the public in November 2020.

    On June 9, 2020, NASA's Parker Solar Probe signaled the success of its fifth close pass by the Sun, called perihelion, with a radio beacon tone. The spacecraft completed the fifth perihelion of its mission two days prior, flying within 11.6 million miles from the Sun's surface, reaching a top speed of about 244,225 miles per hour, which matches the spacecraft's own records for closest human-made object to the Sun and fastest human-made object, set during its fourth orbit on January 29.

    Mission controllers at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, received a "status A" beacon from the spacecraft at 4:40 p.m. EDT. Status A is the best of four possible status signals, and indicates that the spacecraft is operating nominally and the instrument suites are collecting science data. This beacon tone comes after a five-day period where communications with the spacecraft were not possible.

    After completing the solar encounter on June 13, Parker Solar Probe will travel toward Venus for its third flyby of the planet -- the first Venus flyby that will happen as the spacecraft travels away from the Sun, rather than towards the Sun. Parker Solar Probe will use Venus to shed some of its orbital energy and get much closer to the Sun on the following orbit. Passing at an altitude of approximately 516 miles above Venus' surface -- much lower than the previous two flybys but still well above Venus' atmosphere -- Parker Solar Probe will also witness a brief 11-minute solar eclipse during the maneuver while passing through the shadow of the planet.

    Coming off its fifth encounter with the Sun -- and the mission's longest observation campaign (https://blogs.nasa.gov/parkersolarprobe/2020/05/12/parker-solar-probe-begins-longest-science-observation-campaign/) yet -- Parker Solar Probe is now headed toward Venus.

    Early on July 11, 2020 (UTC), the spacecraft will perform its first outbound flyby of Venus, passing approximately 516 miles above the surface as it curves around the planet. Such Venus gravity assists play an integral role in the Parker Solar Probe mission. The spacecraft relies on the planet to rid itself of orbital energy, which in turn allows it to travel ever closer to the Sun after each Venus flyby. The mission's previous two Venus flybys swooped past the Sun-facing side of the planet, and this will be Parker Solar Probe's first pass on Venus' night side.
