МКС 25 раз пришлось уклоняться от космического мусора

Москва. 19 апреля. INTERFAX.RU - За все время эксплуатации Международная космическая станция (МКС) осуществила 25 маневров по уклонению от фрагментов космического мусора, сообщил представитель Центрального научно-исследовательского института машиностроения (ЦНИИмаш) Дмитрий Грудин.

Эти данные приведены в его докладе на конференции "Космический мусор: фундаментальные и практические аспекты и угрозы".

Ближе всего мусор оказался к МКС в 2011 году. Некий объект приблизился к МКС на минимальное расстояние за всю историю станции - около 720 метров. Российских космонавтов предупредили об опасности, по инструкции они переместились в пристыкованный к МКС корабль "Союз".

Ранее специалисты Института прикладной физики Российской академии наук предлагали оснастить МКС лазерами для защиты от космического мусора. По их словам, уже создан стенд для исследования эффективности этого метода.

В данный момент, по оценкам специалистов Московского государственного технического университета имени Н.Э.Баумана, вокруг Земли вращается около 7,2 тыс. тонн космического мусора. На орбите находятся около 18 тысяч объектов размером более 10 сантиметров, в том числе 1200 спутников, 750 тысяч "летающих пуль" (размер каждой "пули" около сантиметра) и около 150 миллионов совсем мелких фрагментов размером меньше миллиметра.

April 19, 2019: International Space Station Configuration. Five spaceships are docked at the space station including Northrop Grumman's Cygnus space freighter and Russia's Progress 71 and 72 resupply ships and the Soyuz MS-11 and MS-12 crew ships.

After its capture this morning at 5:28 a.m. EDT, the Northrop Grumman Cygnus spacecraft was bolted into place on the International Space Station's Earth-facing port of the Unity module at 7:31 a.m. At the time of installation, Cygnus was flying 255 miles above the Indian Ocean just south of Singapore.

Cygnus will remain at the space station until July 23, when the spacecraft will depart the station, deploy NanoRacks customer CubeSats, then have an extended mission of nine months before it will dispose of several tons of trash during a fiery reentry into Earth's atmosphere.

The spacecraft's arrival brings close to 7,600 pounds of research and supplies to space station. Highlights of NASA-sponsored research to advance exploration goals and enable future missions to the Moon and Mars include:

Models for growing increasingly complex materials

Advanced Colloids Experiment-Temperature-10 (ACE-T-10) will test gels in a microgravity environment. This research could aid in the development of increasingly complex materials that may serve as the building blocks for a range of applications on Earth including foods, drugs, and electronic devices. The process also may provide an efficient method to build new materials and equipment in space.

Better life science research in a few drops

Although the space station is well equipped for health and life sciences research, the equipment available for cellular and molecular biology still is limited compared to capabilities found in laboratories on Earth. To address this limitation, CSA designed Bio-Analyzer, a new tool the size of a video game console that astronauts on station easily can use to test body fluids such as blood, saliva, and urine, with just a few drops. It returns key analyses, such as blood cell counts, in just two to three hours, eliminating the need to freeze and store samples.

Analyzing aging of the arteries in astronauts

The Vascular Aging investigation uses ultrasounds, blood samples, oral glucose tolerance tests, and wearable sensors to study aging-like changes that occur in many astronauts during their stay on the space station. It's one of three Canadian experiments exploring the effects of weightlessness on the blood vessels and heart, and the links between these effects and bone health, blood biomarkers, insulin resistance, and radiation exposure. Increased understanding of these mechanisms can be used to address vascular aging in both astronauts and the aging Earth population.

Testing immune response in space

Spaceflight is known to have a dramatic influence on an astronaut's immune response, but there is little research on its effect following an actual challenge to the body's immune system. The rodent immune system closely parallels that of humans, and Rodent Research-12: Tetanus Antibody Response by B cells in Space (TARBIS) will examine the effects of spaceflight on the function of antibody production and immune memory. This investigation aims to advance the development of measures to counter these effects and help maintain crew health during future long-duration space missions. On Earth, it could advance research to improve the effectiveness of vaccines and therapies for treating diseases and cancers.

Big buzz for new robot

A fleet of small robots is set to take on big jobs aboard the space station. Building on the success of SPHERES, NASA will test Astrobee, a robotic system comprised of three cube-shaped robots and a docking station for recharging; the first two are aboard Cygnus. The free-flying robots use electric fans for propulsion and cameras and sensors help them navigate their surroundings. The robots also have an arm to grasp station handrails or grab and hold items. Astrobee can operate in automated mode or under remote control from the ground as it assists with routine chores on station, and requires no supervision from the crew. This has the potential to free up astronauts to conduct more research.

Американский грузовик Cygnus доставил на МКС еду и оборудование

Москва. 19 апреля. INTERFAX.RU - Выведенный на орбиту Земли американский грузовой космический корабль Cygnus в пятницу успешно состыковался с Международной космической станцией (МКС), сообщили в НАСА.

По данным Центра управления полетами НАСА в Хьюстоне, операция по стыковке Cygnus с американским сегментом станции - модулем Unity была завершена в 14:31 по московскому времени. Перед этим сблизившийся с МКС корабль в 12:28 по московскому времени был захвачен с помощью 17-метрового манипулятора Canadarm-2, которым управляла американский астронавт Энн Макклейн. Последующая подводка "грузовика" дистанционной рукой-манипулятором к МКС и сам процесс стыковки осуществлялся по командам с Земли.

Спойлер

Cygnus доставил на МКС около 3,5 тонн груза, в том числе продовольствие, а также оборудование и материалы для проведения десятков научных исследований.

Как сообщалось, грузовой корабль был выведен на орбиту ракетой-носителем Antares, стартовавшей в среду в 23:46 по Москве с космодрома Уоллопс, который размещается на одноименном острове у атлантического побережья американского штата Вирджиния.

Запуск прошел по коммерческому контракту НАСА с корпорацией Northrop Grumman, которой принадлежит ракета-носитель и автоматический грузовой космический корабль.

Это уже 11-й полет американского космического грузовика данного типа к МКС. Был также еще один неудачный запуск в 2014 году, когда "грузовик" не долетел до станции вследствие аварии ракеты-носителя Antares. Первый запуск Cygnus состоялся 18 сентября 2013 года.

Корабль состоит из двух модулей цилиндрической формы: оборудованного солнечными батареями служебного модуля и герметичного грузового модуля.

Cygnus будет находиться в составе МКС до 23 июля. Он заберет с собой со станции мусор и отходы. После расстыковки "грузовик" выведет на орбиту малые спутники.

Cygnus продолжит автономный полет до декабря, когда он будет сведен с орбиты и прекратит свое существование в акватории Тихого океана. Большая его часть сгорит в плотных слоях атмосферы Земли. В общей сложности полет "грузовика" продлится рекордные для этого типа кораблей восемь месяцев.

Экипаж МКС состоит из российских космонавтов Олега Кононенко и Алексея Овчинина, американских астронавтов Энн Макклейн, Кристины Кох и Ника Хейга и канадского астронавта Давида Сен-Жака.

Northrop Grumman's Cygnus Spacecraft Successfully Completes Rendezvous and Berthing with International Space Station

"S.S. Roger Chaffee" delivers approximately 7,600 pounds of cargo to the orbiting laboratory
April 19, 2019

Dulles, Va. – April 19, 2019 – Northrop Grumman Corporation (NYSE: NOC)  today announced that the "S.S. Roger Chaffee" Cygnus™ spacecraft successfully completed its rendezvous and berthing maneuvers with the International Space Station earlier this morning. The mission marks the company's 11th successful berthing with the orbiting laboratory.

Cygnus launched aboard a Northrop Grumman Antares™ rocket on April 17, 2019 from the Mid-Atlantic Regional Spaceport Pad 0A on Wallops Island, Virginia. As the spacecraft approached the space station, Cygnus executed a series of thruster burns to raise its orbit. Once the spacecraft was in close range, crew members on board the space station grappled the spacecraft with the station's robotic arm at 5:30 a.m. EDT. Cygnus was then guided to its berthing port on the nadir side of the station's Unity module and officially installed on to the space station at 7:31 a.m. EDT.

"Our arrival at the space station as the 'S.S. Roger Chaffee' marks a proud moment for the NASA and Northrop Grumman teams," said Frank DeMauro, vice president and general manager, space systems, Northrop Grumman. "As we deliver critical supplies and cargo to the astronauts aboard the space station, we are inspired by Lt. Commander Chaffee's courage and commitment to the human exploration of space. The Cygnus spacecraft represents his planned journey to space in memory of those who took great risks to advance our nation's space program."

Astronaut Roger Chaffee and his crewmates, Virgil "Gus" Grissom and Ed White II, all died in a tragic accident after a fire occurred in the space capsule during a simulation of the Apollo 1 launch in 1967. While his crewmates had flown to space on previous missions, Chaffee had not yet traveled to space. The naming of Cygnus in honor of his memory recognizes his legacy and valued contributions to human spaceflight.

Cygnus arrived at the space station with nearly 7,600 pounds (approximately 3,450 kilograms) of cargo, supplies and scientific experiments. The crew is now scheduled to open Cygnus' hatch and make initial ingress into the cargo module to begin unloading the pressurized cargo. Cygnus will remain docked at the station for approximately three months before departing on secondary missions.

Once Cygnus departs the station, the spacecraft will begin a secondary mission to deploy CubeSats for two commercial customers. Cygnus will reposition to deploy three CubeSats using a NanoRacks deployer in the Company's seventh commercial mission. The Slingshot CubeSat Deployer system is also on board and marking its second mission on a Cygnus spacecraft. Slingshot is a flexible platform that can fly hosted payloads and CubeSats. The system is scheduled to be installed by astronauts while Cygnus is docked to the station in preparation for another round of CubeSat deployments during the next phase of its mission.

After the CubeSats are deployed, Cygnus will remain in orbit for an extended duration mission, an achievement marking a "first" for the spacecraft as it demonstrates capabilities beyond cargo supply and disposal. This newest innovation showcases Cygnus as a future testbed for various types of hosted payload missions. Upon completion of its secondary missions, Cygnus will perform a safe, destructive reentry into Earth's atmosphere over the Pacific Ocean.

Fluids Integrated Rack (FIR)/Light Microscopy Module (LMM)/Biophysics-6 experiment start:

Спойлер

As a followup to the discovery of the plate with damaged sample capillary(s) on Monday, today the crew removed another LMM/Biophysics-6 (Bio-6) plate fr om MELFI and allowed it to thaw. Following a good inspection, it was ins erted in the LMM to begin the experiment. LMM/Bio-6, more formally known as Growth Rate Dispersion as a Predictive Indicator for Biological Crystal Samples Wh ere Quality Can Be Improved with Microgravity Growth, studies ground-based predictions of which crystals benefit from crystallization in microgravity, wh ere Earth's gravity does not interfere with their formation. The plate installed contains samples of Geranylgeranyl pyrophosphate synthase (GGPPS) which is a protein produced in osteoporosis, multiple myeloma, and Paget's disease. Observing crystallized proteins via X-ray crystallography on the ground allows scientists to determine how they are built, which can explain how they work or how other molecules, such as drugs, might interact with them.

Rodent Research-12:

Спойлер

The crew performed the Habitat installation and participated in a crew conference to discuss RR-12 and transfers of the mice. The actual mouse transfer from NG-11 to ISS occurs Saturday. RR12 has 2 specific aims: 1) To determine the impact of the spaceflight environment on primary and secondary antibody responses. 2) Establish that adjuvants that function through Tlr9 receptors are effective during spaceflight. Rodent Research-12, Tetanus Antibody Response by B cells in Space (TARBIS), examines the effects of spaceflight on the function of antibody production and immune memory. Spaceflight is known to have a dramatic influence on immune response, but there is little research on its effect following an actual challenge to the body's immune system. Using a mouse model makes this possible, as the mouse immune system closely parallels that of humans.
