ЦитироватьThe next American polar-orbiting weather satellite that will feed long-range forecasts and track environmental trends has slipped into space-like testing ahead of launch.

The Joint Polar Satellite System spacecraft No. 1 will be launched atop a United Launch Alliance Delta 2 rocket from Vandenberg Air Force Base in California on Jan. 20 at 1:47 a.m. local (4:47 a.m. EST; 0947 GMT).

The project is a collaboration between the National Oceanic and Atmospheric Administration (NOAA) and NASA.

From a 512-mile orbit, tilted 98.7 degrees to the equator and traveling pole-to-pole, JPSS 1 will survey the entire globe twice per day with five sensor packages.

The craft will provide imagery, atmospheric temperature and humidity profiles, and land and ocean surface temperature observations, all of which are key ingredients for weather forecasting. In addition, the satellite will measure ozone levels and reflected solar radiation from the planet.

The satellite will replace the existing Suomi NPP spacecraft that launched in 2011 for a five-year mission as a gapfiller between NOAA's legacy weather satellite constellation and the new JPSS generation.

JPSS 1 will be renamed NOAA 20 once declared operational. It is designed to last seven years.

Spacecraft manufacturer Ball Aerospace has begun environmental testing at the company's Fisher Complex in Boulder, Colorado, to simulate the harsh conditions that JPSS 1 will face during its launch and once in orbit.

Tests include acoustic, vibration and electromagnetic interference and electromagnetic compatibility, followed this summer by thermal vacuum testing to expose the craft and instruments to the extreme temperature swings experienced in space.

All of the checks will culminate with certification that the satellite is ready to ship to its California launch site this fall.

"Heading into the final series of environmental tests marks completion of the development and integration phase, on time and on schedule," said Jim Oschmann, vice president and general manager for Ball's Civil Space business unit.

"We look forward to having the next polar-orbiting satellite on-orbit to ensure continuous coverage of precise and timely weather information."

JPSS 1 will be the next-to-last flight for the venerable Delta 2 rocket.

NPP [Ball]
 
NASA and the NPOESS Integrated Program Office (IPO) are developing NPP (NPOESS Preparatory Project) as the mission precursor to the NPOESS (http://space.skyrocket.de/doc_sdat/npoes-1.htm) mission and to provide data continuity between the EOS Terra (http://space.skyrocket.de/doc_sdat/eos-am-1.htm) and Aqua (http://space.skyrocket.de/doc_sdat/eos-pm-1.htm) missions and the NPOESS (http://space.skyrocket.de/doc_sdat/npoes-1.htm) launch slated for late in the decade. NPP also provides the NPOESS IPO with risk reduction for the NPOESS program through early flight validation of critical NPOESS (http://space.skyrocket.de/doc_sdat/npoes-1.htm) sensors.
Ball Aerospace will employ a modified BCP-2000 (http://space.skyrocket.de/doc_sat/ball_bcp-2000.htm) to accommodate NPP's five instruments:
 [LIST][/li][li]Visible Infrared Imaging Radiometer Suite (VIIRS)[/li][li]Cross-track Infrared Sounder (CrIS)[/li][li]Advanced Technology Microwave Sounder (ATMS)[/li][li]Ozone Mapper/Profiler Suite (OMPS)[/li][li]Clouds and the Earth Radiant Energy System (CERES)[/LIST]
These instruments will study global change, including atmospheric temperature and humidity sounding, sea-surface temperature, land and ocean biological productivity, cloud and aerosol properties and global ozone levels. The Ozone Mapping and Profiler Suite Limb Subsystem (OMPS-Limb) was added after it has been removed from NPOESS (http://space.skyrocket.de/doc_sdat/npoes-1.htm) in 2006.
After the cancellation of NPOESS in 2010, NPP is the only element retained. It will be used as an operational meteorological satellite in the JPSS (Joint Polar Satellite System).
NPP was successfully launched on a Delta-7920-10C (http://space.skyrocket.de/doc_lau_det/delta-7920.htm) booster from Vandenberg Air Force Base. After initial check out in orbit, NASA renamed the spacecraft on 24th January 2012 to Suomi National Polar-orbiting Partnership, or Suomi NPP in honor of the late Verner E. Suomi, a meteorologist at the University of Wisconsin who is recognized widely as "the father of satellite meteorology."
A second, nearly identical satellite called JPSS 1 has been ordered in September 2010 for launch in 2016. It will also be launched on a Delta-7920-10C (http://space.skyrocket.de/doc_lau_det/delta-7920.htm) rocket. The differences to NPP are: increased mission assurance requirements, increased lifetime to seven years, and addition of a Ka-band downlink.

The next-to-last Delta 2 rocket is being stacked at its California launch site to take flight in January to put a civilian weather satellite into polar orbit.
The first stage, interstage, nine strap-on boosters and second stage of the United Launch Alliance rocket are being pieced together over the next two weeks to form the 7920-configured rocket at Vandenberg Air Force Base's Space Launch Complex 2-West pad.
Lean operations dictated that the on-pad assembly would occur now while workers could break away from their duties on other rockets. They put up the first stage today.
The Delta 2 is protected against the weather by its all-enclosing gantry that cocoons the vehicle entirely.
The stages recently shipped from the United Launch Alliance production factory in Decatur, Alabama to Vandenberg. The solids arrived from Orbital ATK last year.
Launch is targeted for Jan. 20 at 1:47 a.m. local (4:47 a.m. EST; 0947 GMT) carrying the first Joint Polar Satellite System spacecraft.
JPSS is a collaborative project between NASA — which ordered the spacecraft, instruments and launcher — and satellite operator NOAA.

The Ball Aerospace-built satellite will fly in a 512-mile-high orbit, tilted 98.7 degrees to the equator and travel pole-to-pole to survey the entire globe twice per day with five sensor packages.
Data from JPSS 1 will include imagery, atmospheric temperature and humidity profiles, land and ocean surface temperature observations, and measure ozone levels and the reflected solar radiation from the planet.
The information is ingested by numerical computer models to generate weather forecasts and monitor climate trends.
The satellite will be renamed NOAA 20 once operational. It has a 7-year design life.
JPSS 1 is a direct successor in design and mission to the current Suomi NPP weather satellite launched by a Delta 2 in 2011.

Stacking of the rocket began today when the first stage was lifted vertically with the help of the pad's mobile service tower and placed atop the launch mount. The 90-foot-long, 8-foot-diameter stage was erected from its transport trailer and the gantry then rolled along its rail tracks to the mount for the rocket to be lowered and secured.
The barrel-like interstage adapter will be attached tomorrow, the nine solids will be hung from July 19 through the 27th, and the second stage will be hoisted into place on July 29 to complete the basic build up of the rocket.
The Delta 2 will be powered away from the pad by its kerosene-fueled Aerojet Rocketdyne RS-27A main engine and six of the solids firing to produce a combined thrust in excess of 750,000 pounds. The remaining three solids ignite a minute into flight.
The second stage will burn its Aerojet Rocketdyne AJ10-118K engine, fueled with storable hypergolic propellants, to reach an initial parking orbit and a further time to deliver the satellite into the prescribed orbit.
The payload is shrouded during atmospheric flight by a 10-foot-diameter composite nose cone.
The Delta 2 will stand 128 feet tall and weigh 509,000 pounds at liftoff.

The venerable Delta 2 has achieved 151 successes in 153 flights since debuting on Valentine's Day 1989. Its current consecutive success streak stands at 98 flights dating back to May 1997.
JPSS 1 will be the 53rd NASA mission to use the Delta 2.
Delta 2 was the spaceflight workhorse that deployed the Global Positioning System constellation and sustained its capabilities for billions of users around the world, as well as launched such science missions as the Mars rovers Spirit and Opportunity, the Kepler planet finder and the Dawn and MESSENGER probes.
But the Air Force, the anchor tenant of the Delta 2 from its inception in the wake of the shuttle Challenger disaster, retired the military's use of the rocket in 2009 and shifted GPS launches to the more powerful Atlas 5 and Delta 4 boosters.
With so few payloads in the Delta 2's weight class, United Launch Alliance opted to phase out the rocket. The manufacturing factory is using up key elements that were stockpiled before production lines were shut down several years ago.
After JPSS 1, the final planned Delta 2 rocket will launch NASA's ICESat 2 laser altimeter science satellite later in 2017.
Pieces remain in existence to build one additional Delta 2, but it lacks a customer and will likely become a museum piece to pay tribute to the rocket's remarkable legacy.

ЦитироватьFirst JPSS satellite launch delayed two months

WASHINGTON — The launch of the first next-generation polar orbiting weather satellite has slipped by two months because of issues with the spacecraft and its ground systems, the National Oceanic and Atmospheric Administration confirmed Aug. 5.
NOAA spokesman John Leslie said the launch of the Joint Polar Satellite System (JPSS) 1 spacecraft, which had been scheduled for January 2017, is now expected to take place in March.
"Based on recent tests of the flight and ground systems and an assessment of the remaining work to bring the system to flight readiness, NOAA has determined it cannot meet the Jan. 20, 2017 launch date for JPSS-1 with reasonable confidence," Leslie said in a statement provided to SpaceNews. He did not elaborate on the issues causing the delay, although sources say a problem with one of the spacecraft's instruments may be part of the reason for the delay.
Leslie said that NOAA, working with NASA, who is responsible for the JPSS-1 launch, has set a new "launch planning date" for the mission of March 2017. The spacecraft will be launched on a United Launch Alliance Delta 2 fr om Vandenberg Air Force Base in California.
"NOAA is committed to the successful launch and operation of the mission, which is critical to NOAA's commitment of providing the best, most reliable, long-term weather and climate prediction," Leslie said.
Jackie Berger, a spokeswoman for Ball Aerospace, the JPSS-1 prime contractor, said Aug. 5 the company was "supporting the NASA/NOAA schedule" but referred questions about the details of the delay to NOAA. "We continue to work closely with NASA, NOAA and JPSS contractor team in order to achieve the March 2017 launch date," she said.
News of the slip comes less than a month after a House Science Committee hearing wh ere David Powner, director of information technology management issues at the U.S. Government Accountability Office, said he "still remained concerned" about the launch date for JPSS-1 even though the project, at the time, appeared to be on track.
The project, Powner said at the July 7 hearing, had missed interim milestones involving the spacecraft itself, one of its instruments and the ground systems. Two key upcoming milestones, he said, were the delivery of the ground system scheduled for August and a thermal vacuum test of the spacecraft that was scheduled to begin in late July. Berger said Aug. 5 that the thermal vacuum test is current scheduled to start in mid-August.
Any delay in the launch of JPSS-1 raises concerns about a data gap. The Advanced Technology Microwave Sounder instrument on the Suomi National Polar-orbiting Partnership spacecraft is in danger of failing, and the loss of data should it fail before JPSS-1, carrying a similar instrument, enters service could adversely affect the accuracy of weather forecasts.
The delay may trigger additional congressional scrutiny of the program, as well as increased emphasis on the use of commercial data purchases to mitigate any data gaps. "Time and again we have seen that our government satellite systems are beset with cost overruns, mismanagement and a narrow mindset," Rep. Lamar Smith (R-Texas), chairman of the House Science Committee, said in an Aug. 5 statement to SpaceNews. "I call on NOAA to implement all available solutions to avoid a gap in weather data."

ВАШИНГТОН, 6 сентября. /Корр. ТАСС Дмитрий Кирсанов/. США намерены в ноябре осуществить запуск своего первого метеорологического спутника следующего поколения. Об этом сообщило Национальное управление по исследованию океанов и атмосферы, которое структурно функционирует при министерстве торговли США.
Старт ракеты-носителя Delta II с аппаратом JPSS-1 запланирован на 10 ноября. Этот спутник предназначен для дистанционного зондирования Земли, а также наблюдений за мировым океаном и атмосферой. Американские специалисты рассчитывают, что предстоящая эксплуатация пяти научных приборов, установленных на этом космическом аппарате, позволит прежде всего существенно повысить точных прогнозов погоды. Спутник будет находиться на полярной орбите, совершая в сутки 14 витков вокруг Земли на высоте 824 км над ней и обеспечивая ее полный охват.
Аппарат JPSS-1 и его научные инструменты были созданы в общей сложности пятью различными американскими компаниями, срок его эксплуатации должен составить семь лет. Запуск произведет компания United Launch Alliance, являющаяся совместным предприятием, созданным в свое время корпорациями Boeing и Lockheed Martin. В будущем Национальное управление по исследованию океанов и атмосферы предполагает приобрести еще три таких спутника. Американское правительство надеется, что эти четыре космических аппарата станут на ближайшие 20 лет основой технической системы нацуправления, позволяющей обеспечивать точные предсказания погоды в глобальном масштабе на семь дней вперед.
В пятницу спутник JPSS-1, который после вывода на орбиту получит наименование NOAA-20, был доставлен на базу ВВС США Ванденберг (штат Калифорния). Именно с нее должна стартовать ракета Delta II, которой предстоит вывести аппарат на орбиту. В настоящее время идет подготовка к размещению спутника в головном обтекателе ракеты-носителя.

ЦитироватьNext-generation weather satellite shipped to launch base in California
September 6, 2017 (https://spaceflightnow.com/2017/09/) Justin Ray (https://spaceflightnow.com/author/justin-sfn-ray/)

A new weather observatory that will track storms across the globe as it orbits from pole to pole has been trucked to its launch site in California for a long-awaited ascent into space this November.

The first spacecraft in the Joint Polar Satellite System, JPSS No. 1, is targeting a liftoff Nov. 10 at 1:47:03 a.m. local time (4:47:03 a.m. EST; 0947:03 GMT) atop a United Launch Alliance Delta 2 rocket from Vandenberg Air Force Base.

JPSS is the next American polar-orbiting weather satellite series that will collect data needed for long-range forecasts and track environmental trends. It is is a collaboration between NOAA for operational weather needs and NASA for climate research.

Built by Ball Aerospace & Technologies Corp. in Boulder, Colorado, the spacecraft left its factory for the 1,530-mile road-trip to Vandenberg, arriving early Friday, Sept. 1 at the Astrotech payload processing facility on the base.

It has been a struggle to reach this point after several technical issues with the satellite kept it in Boulder nearly a year longer than planned.

Launch dates came and went throughout this year while engineers worked through problems with one the weather instruments on the satellite, an onboard computer that was misbehaving and potentially defective capacitors inside the spacecraft that were called into question in an industry-wide alert issued in late June that was a last-minute curveball thrown at the team.

An elusive issue with the Advanced Technology Microwave Sounder instrument, dogging the mission for months, was creating noisy data on several of its channels when heaters were activated. Extensive testing was done to characterize the problem, ultimately requiring removal of the ATMS instrument from the satellite to isolate the cause. Finally, an intermittent cable short within the instrument was deemed the root cause, cable insulation was added and the instrument retested successfully.

One by one, the issues were fixed, a number of suspect capacitors were pulled out and replaced with ones from a good batch, and JPSS 1 was cleared to ship to the launch site.

Officials say a nominal launch processing flow has begun with some reserve days included, should any work take longer than planned.

"The JPSS 1 team has done an incredible job getting this extremely capable satellite prepared for launch and ready to send back quality environmental data soon after it is in orbit," said Stephen Volz, director of NOAA's Satellite and Information Service.

Now at Vandenberg, the satellite has been safely removed from its shipping container and environmental monitoring data reviewed to assure that no excessive temperature, humidity, shock or vibration events occurred during the multi-state transport.

Over the next month, JPSS 1 and its five government-furnished instruments will be put through a series of final mechanical, electrical and antenna tests to make sure that all systems are working as expected. Also, final inspections and cleaning will be performed and thermal blankets buttoned up for flight.

The lithium ion flight batteries have been charged and will be maintained at proper levels from now until launch.

And the spacecraft's propulsion system will be loaded with on-orbit maneuvering fuel.

The Delta 2 rocket, making its next-to-last flight, will be used to boost the 5,000-pound satellite into a sun-synchronous polar orbit. The half-million-pound launcher features nine solid-fuel boosters — six ignited on the pad and three that light a minute into flight — a kerosene-fed first stage, hypergolic second stage and a 10-foot-diameter composite nose cone.

Stacking of the rocket at the Space Launch Complex 2-West pad began last July, before the payload delays began, when the first stage was erected. The process was completed in April by hanging the solids and hoisting the second stage.

The satellite, standing 14 feet tall, will be delivered to the launch pad in late October, followed by installation of the fairing halves.

The daily launch window lasts just 62 seconds, a tight requirement to sync up the JPSS 1 orbit with the aging Suomi NPP weather observatory that it will replace. Depending on launch day factors, liftoff could be re-targeted for the exact center of the window for optimal performance — at 1:47:35.328 a.m. local time.

From a 512-mile orbit, tilted 98.7 degrees to the equator and traveling pole-to-pole, the JPSS 1 satellite will survey the entire globe twice per day with its sensor packages.

A single solar wing powers JPSS 1, giving the craft 2,750 watts of electricity at the beginning-of-life from a three-panel array that deploys to 32 feet wide in space.

JPSS will provide visible and infrared imagery, atmospheric temperature and humidity profiles, and land and ocean surface temperature observations, all of which are key ingredients for weather forecasting. In addition, the satellite will measure ozone levels and reflected solar radiation from the planet.

JPSS 1 is equipped with a suite of five instruments:

After approximately 90 days of post-launch commissioning, JPSS 1 should be ready to assume primary duties from S-NPP for NOAA's National Weather Service. S-NPP will become a backup satellite, while JPSS 1 is rebranded NOAA 20.

Ball Aerospace built both satellites, and JPSS 1 represents an evolutionary copy of S-NPP, with some significant upgrades. The S-NPP spacecraft was built to a five-year lifespan requirement and JPSS 1 was enhanced to a seven-year design.

What's more, high data rate instruments will use a more reliable data bus, the propulsion system's thruster catalyst was changed, the power system uses lithium-ion batteries rather than nickel-hydrogen technology and more efficient solar cells and there's a new Ka-band transmitter for sending stored data to NASA's Tracking and Data Relay Satellites and faster delivery to the ground.

The JPSS 1 satellite's legacy can be traced to 1960 and the launch of TIROS, the first Television Infrared Observation Satellite. Upgrades and technology advancements have evolved the civilian weather observatories through the decades.

There have been 44 NOAA polar orbiters launched in the 57-year line using Delta, Atlas and Titan rockets.

The second JPSS satellite is under construction at Orbital ATK for its launch by an Atlas 5 in 2021.

Four sequential satellites — JPSS 1, 2, 3 and 4 — are planned under the Joint Polar Satellite System program, ensuring observations to 2038.

"The new JPSS satellite will join GOES-16 as we are confronting one of the most tragic hurricane seasons in the past decade," said Secretary of Commerce Wilbur Ross. "The JPSS satellite system will provide advanced forecasting on not only hurricanes, but also dangerous weather events threatening communities across the United States."

The satellite, called JPSS-1, will provide meteorologists with a variety of observations, such as atmospheric temperature and moisture, sea-surface temperature, ocean color, sea ice cover, volcanic ash and fire detection. Forecasters will be able to use the data to better predict weather events and hazards, such as a hurricane's track, and when a hurricane will intensify or weaken, as well as identifying power outages in addition to locating and evaluating damage following a storm.

Circling the globe 14 times a day

JPSS-1, which will be known as NOAA-20 when it reaches polar orbit, will join the Suomi National Polar-orbiting Partnership (Suomi NPP), a joint NOAA-NASA weather satellite, giving the U.S. the benefit of two, sophisticated polar satellites in the same orbit. Each will circle the globe 14 times a day, 50 minutes apart and provide full, global observations for U.S. weather prediction. After it successfully clears the on-orbit test phase, NOAA-20 will become the nation's primary polar weather satellite and Suomi NPP will become its back up.

"Having two advanced polar satellites in the same orbit will ensure our numerical weather models have the necessary, critical data to support forecasts up to seven days ahead of extreme weather events," said Stephen Volz, Ph.D., director of NOAA's Satellite and Information Service.

"Eighty-five percent of the data flowing into our weather forecast models come from polar-orbiting satellites, such as Suomi NPP and the new JPSS series," said Louis W. Uccellini, Ph.D., director of NOAA's National Weather Service. "Using polar satellite data, we have been able to provide emergency managers with more accurate forecasts, allowing them to pre-position equipment and resources days before a storm. JPSS will continue this trend."

Major Upgrade

The five next-generation instruments on JPSS will be a major upgrade from NOAA's legacy polar-orbiting satellites. JPSS will provide more detailed information about atmospheric temperature and air moisture leading to more accurate near-term weather predictions. Over longer timescales, this data will help improve our understanding of climate patterns that influence the weather, such as El Nino and La Nina.

The JPSS program is a partnership between NOAA and NASA that will oversee all the satellites in the series. NOAA funds and manages the program, operations and data products. NASA develops and builds the instruments, spacecraft and ground system and launches the satellites for NOAA.

"The launch of JPSS-1 continues the strong, decades-long partnership between NOAA and NASA in developing state-of-the-art Earth observation satellites," said Sandra Smalley, director of NASA's Joint Agency Satellite Division. "We are proud to contribute to NOAA's continued leadership in critical weather forecasting throughout the entire JPSS series."

Ball Aerospace designed and built the JPSS-1 satellite bus, and Ozone Mapping and Profiler Suite instrument, integrated all five of the spacecraft's instruments and performed satellite-level testing and launch support. Raytheon Corporation built the Visible Infrared Imaging Radiometer Suite and the Common Ground System. Harris Corporation built the Cross-track Infrared Sounder. Northrop Grumman Aerospace Systems built the Advanced Technology Microwave Sounder and the Clouds and the Earth's Radiant Energy System instrument.

NASA-TV will cover the launch live and can be viewed at www.nasa.gov/ntv, starting at 1:15 a.m. PST on November 10.

JPSS Overview

The Joint Polar Satellite System is the nation's next generation of polar-orbiting environmental satellites. JPSS satellites circle the Earth from pole-to-pole and cross the equator 14 times daily in the afternoon orbit, providing full global coverage twice per day. Polar satellite data is considered the backbone of the weather forecast and NOAA's National Weather Service uses JPSS data as a critical input for numerical forecast models, providing the basis for essential, mid-range (3- to 7-day) forecasts. These forecasts allow for early warnings and enable emergency managers to make timely decisions to protect American lives and property, including ordering effective evacuation.    JPSS satellites also provide critical observations in polar regions. In Alaska, JPSS supports essential forecasting fore economically vital aviation, maritime, oil and gas industries. JPSS also enables scientists and forecasters to monitor and predict weather patterns with greater accuracy and to study long-term climate trends by extending the more than 30-year satellite data record.

The satellites of the JPSS constellation host state-of-the-art instruments, including the Advanced Technology Microwave Sounder (ATMS), the Cross-Track Infrared Sounder, the Visible Infrared Imaging Radiometer Suite, the Ozone Mapping and Profiler Suite, and an instrument that measures the Earth's radiation budget. Together, these instruments gather global measurements pf atmospheric, terrestrial, and oceanic conditions, including atmospheric temperature and moisture, hurricane intensity, clouds, rainfall, dense fog, volcanic ash, fire location and smoke plumes, sea and land surface temperatures, vegetation, snow and ice cover, and ozone. Information from JPSS satellites supports every area of NOAA's mission, including ensuring a more Weather-Ready Nation.

The first spacecraft in NOAA's Joint Polar Satellite System — JPSS 1 — was raised into the mobile gantry Tuesday at Space Launch Complex 2-West at Vandenberg for attachment atop the Delta 2 rocket, which had its first stage erected on the launch mount there last year to await the payload's arrival.

The Delta 2's second stage and nine solid rocket boosters were later added, and the addition of the JPSS 1 spacecraft this week moves the rocket one step closer to being fully assembled.

Fueled for a planned seven-year mission, the JPSS 1 satellite will be closed up inside the Delta 2's composite payload fairing ahead of liftoff Nov. 10 at 1:47 a.m. PST (4:47 a.m. EST; 0947 GMT).

ULA engineers inspected the Delta 2 rocket following a 4.3-magnitude earthquake centered just off Vandenberg's coast Thursday and found no issues, according to a tweet by Tory Bruno, the company's president and CEO.

The $1.6 billion JPSS 1 satellite is the first member of NOAA's new-generation series of polar-orbiting weather satellites, extending a line of meteorological spacecraft dating back to 1960. JPSS 1 carries five instruments to gather data on storms, clouds, fog, smoke plumes and snow and ice cover, measure atmospheric temperature and moisture content, and study the health of Earth's ozone layer.

With a launch mass of nearly 5,000 pounds (about 2,200 kilograms), JPSS 1 is the first of four new polar-orbiting satellites under development by NOAA in partnership with NASA. The quartet will ensure the U.S. weather agency continues receiving measurements from polar orbit through 2038, officials said.

Polar-orbiting satellites generate data inputs for global numerical forecast models, helping make medium-range weather predictions. NOAA's Suomi NPP satellite, launched in October 2011, is currently the primary U.S. civilian-operated polar-orbiting weather satellite, flying in an orbit around 500 miles (800 kilometers) above Earth that takes it over regions of the planet during the afternoon.

NOAA, the U.S. Air Force and Eumetsat, the European weather satellite agency, have a partnership to share data collected by each organization's polar-orbiting meteorological observatories. The U.S. military's DMSP satellites fly in a similar polar orbit with early morning passes, and Europe's Metop spacecraft are in orbits timed to make observations in mid-morning.

Suomi NPP was built as a demonstration for the new-generation NOAA weather satellites, but forecasters now rely on its measurements to fill a gap between the last of the previous line of polar-orbiting platforms, which launched in 2009, and JPSS 1.

"JPSS 1 is going to bring the latest, most advanced technology that NOAA has ever flown in polar orbit to produce accurate three-to-seven-day weather forecasts," said Greg Mandt, director of the JPSS program at NOAA.

NOAA began a refresh of its higher-altitude geostationary satellites with the launch of GOES R — now named GOES 16 — in November 2016. Positioned in orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator, the GOES satellites provide near-continuous imagery of developing storm systems, hurricanes and other weather phenomena for short-term forecasting.

The polar-orbiting meteorological satellites monitor broader atmospheric conditions, helping predict changing weather patterns up to a week in advance.

JPSS 1 arrived at Vandenberg on Sept. 1 after shipment from its factory at Ball Aerospace and Technologies Corp. in Boulder, Colorado.

"Since arriving at Vandenberg Air Force Base on Sept. 1, the JPSS 1 team — NOAA, NASA, Ball, Harris, Raytheon and Northrop Grumman — has completed several critical milestones in preparation for launch," said Rob Strain, president of Ball Aerospace. "The outstanding collaboration between industry and government partners will ensure a system that will help save lives and resources for many years to come."

Technicians fueled the satellite with hydrazine for its maneuvering thrusters, pressurized the propulsion system to flight pressure, completed a final thermal blanket closeout, and cleaned the spacecraft, Ball Aerospace said in a statement.

The Delta 2 rocket will place the spacecraft in a sun-synchronous-type orbit aligned with the flight path of Suomi NPP, allowing the two weather satellites to fly over the same part of the planet 50 minutes apart to conduct tandem observations.

JPSS 1 will be renamed NOAA 20 when it enters service next year.

The Nov. 10 launch will be the second-to-last flight of the venerable Delta 2 rocket, which has conducted 151 missions since its introduction in 1989, launching interplanetary missions to the moon, Mercury, Mars, comets and asteroids, NASA's planet-hunting Kepler observatory, and numerous commercial and military satellites, including the bulk of the GPS navigation network in the 1990s and 2000s.

One more Delta 2 is set to launch from Vandenberg in late 2018 with NASA's ICESat 2 mission.

The last in a series of instruments that measure the solar energy reflected by Earth, the heat the planet emits, and the role of clouds in that process will launch to orbit next month.

The Clouds and the Earth's Radiant Energy System Flight Model 6 (CERES FM6), developed by Northrop Grumman and managed by NASA's Langley Research Center in Hampton, Virginia, is scheduled to launch Nov. 10 aboard the National Oceanic and Atmospheric Administration's Joint Polar Satellite System-1 (JPSS-1) from Vandenberg Air Force Base in California.

Liftoff aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2W is targeted for 1:47 a.m. PST (4:47 a.m. EST) at the opening of a 65-second launch window. JPSS, a collaborative effort between NOAA and NASA, represents significant technological and scientific advancements in observations used for severe weather prediction and environmental monitoring.

"CERES provides critical observations of how solar energy absorbed and terrestrial infrared radiative energy emitted by Earth are distributed over the planet, thereby helping to improve seasonal weather and long-term climate predictions," said Norman Loeb, principal investigator for NASA's Radiation Budget Science Project. "CERES FM6 will extend the existing CERES record, helping to quantify decadal changes in Earth's energy budget and clouds, and improve our understanding of the mechanisms that drive those changes."

Global CERES data allow scientists to validate models that calculate the effect of clouds on planetary heating or cooling. Those data also help improve seasonal climate forecasts, including cloud and radiative aspects of large-scale climate events like El Niño and La Niña. In addition, CERES data can be used for assessing the radiative effects and climatic impact of natural disasters like volcanic eruptions, major floods and droughts.

For 32 years, Langley instruments have provided stewardship of critical climate observations both through CERES and the Earth Radiation Budget Experiment (ERBE), which began measurements in 1984.

Five CERES instruments already are on orbit aboard three satellites. CERES FM1 and FM2 launched in 1999 on the Terra satellite. CERES FM3 and FM4 launched in 2002 on the Aqua satellite. CERES FM5 launched in 2011 on the Suomi NPP satellite. A CERES instrument that launched on the TRMM satellite in 1997 stopped collecting data in 2000.

"This final instrument from a program that has spanned more than 20 years represents the culmination of a long and fruitful partnership with Northrop Grumman in designing, building, and operating the CERES instruments," said CERES Project Scientist Kory Priestley. "We fully expect the FM-6 instrument to function as well as its predecessors, providing critical observations that benefit humanity for another 10 to 15 years."

JPSS-1 to Provide More Accurate Environmental Forecasts

By Bob Granath
NASA's Kennedy Space Center, Florida

NASA is preparing to launch the Joint Polar Satellite System (http://www.jpss.noaa.gov/)-1, or JPSS-1, satellite on behalf of the National Oceanic and Atmospheric Administration (NOAA) to provide essential data for timely and accurate weather forecasts and for tracking environmental events such as forest fires and droughts.

JPSS-1 is the first in NOAA's series of four, next-generation operational environmental satellites designed to circle the Earth in a polar orbit. The JPSS program is a partnership between NOAA and NASA that will oversee all the satellites in the JPSS series. NOAA funds and manages the program, operations and data products. NASA develops and builds the instruments, spacecraft and ground system and launches the satellites for NOAA.

The mission is scheduled to begin at 4:47 a.m. EST (1:47 a.m. PST), Nov. 10, 2017, with JPSS-1 atop a United Launch Alliance (ULA) Delta II (https://www.nasa.gov/centers/kennedy/launchingrockets/delta-II-definitions.html) rocket lifting off from Space Launch Complex 2 (SLC-2) at Vandenberg Air Force Base in California.

Built by Ball Aerospace of Boulder, Colorado, the satellite will pass over the equator about 14 times each day, covering the globe twice every 24 hours. As it works, JPSS-1 will gather measurements of atmospheric, terrestrial and oceanic conditions, including sea and land surface temperatures, vegetation, clouds, rainfall, snow and ice cover, fire locations, atmospheric temperature, water vapor and ozone.

With these varied observations, JPSS will give environmental experts more accurate warnings in advance of hurricanes, tornadoes and blizzards. During its planned 10-years in orbit, JPSS-1 also will aid in assessing hazards such as droughts, forest fires, poor air quality and harmful coastal waters.

Preparations for the launch JPSS-1 rocket have been underway for more than a year. The first stage of the Delta II rocket arrived at Vandenberg's NASA Hangar 836 on April 4, 2016. Later in the month, the Delta II interstage and second stage also reached the West Coast launch site.

On July 12, 2016, the first stage of the ULA Delta II rocket was transported to SLC-2 at Vandenberg and positioned on the launch pad. The rocket's second stage was hoisted into the pad's gantry on April 11, 2017, and mounted atop the first stage of the rocket.

The JPSS-1 satellite arrived at Vandenberg on Sept. 1, 2017, for preflight preparations in the Astrotech Processing Facility. Following checkouts, the spacecraft was encapsulated in its payload fairing and moved to SLC-2 and mounted atop the Delta II rocket.

JPSS-1 will follow the joint NOAA/NASA Suomi National Polar-orbiting Partnership (https://www.nasa.gov/mission_pages/NPP/main/index.html), which was launched in 2011. Originally planned as a research and risk-reduction mission in the JPSS series, NOAA has been using Suomi NPP as its primary operational satellite for global weather observations since May 2014.

After it reaches orbit 512 miles above the Earth, JPSS-1 will be known as NOAA-20. Future satellites planned for the JPSS constellation include JPSS-2, scheduled for launch in 2021, JPSS-3 in 2026 and JPSS-4 in 2031. The series of four JPSS satellites are expected to span 20 years.

The launch of a new U.S. weather satellite from Vandenberg Air Force Base in California has been delayed at least four days to Nov. 14, allowing time for technicians to remove and replace a faulty battery on the payload's Delta 2 rocket, United Launch Alliance said Monday.

Спойлер

The satellite is set to head into an orbit circling over Earth's poles, replenishing NOAA's fleet of space-based meteorological sentinels and inaugurating a new generation of weather observatories to collect images of clouds and measurements of atmospheric temperature and moisture profiles.

The launch was set for Friday, but officials ordered a delay to swap out a faulty battery on the Delta 2 rocket set to carry the JPSS 1 satellite into orbit, ULA said in a statement Monday. The launcher and the spacecraft remain stable, the company said.

Liftoff from Space Launch Complex 2-West at Vandenberg is now targeted for no sooner than next Tuesday, Nov. 14, at 1:47 a.m. PST (4:47 a.m. EST; 0947 GMT). The launch window extends for approximately one minute, and the time remains fixed each day.

The first spacecraft in NOAA's Joint Polar Satellite System was mounted atop the Delta 2 rocket Oct. 24, and technicians have encapsulated the satellite inside the launcher's payload shroud at the seaside launch complex on California's Central Coast. The encapsulation milestone completed assembly of the 128-foot-tall (39-meter) rocket, which will take off with a boost from nine solid-fueled strap-on motors.

Officials gave approval to proceed with final launch preparations during a flight readiness review last week, but managers ordered the battery swap Monday.

The launch will mark the penultimate flight of a Delta 2 rocket, which entered service in 1989 and has launched numerous military, commercial and scientific missions with 151 successful flights to date. One more launch of the medium-class Delta 2 rocket is slated for next year with NASA's ICESat 2 satellite.

The nearly 5,000-pound (2,200-kilogram) JPSS 1 satellite was manufactured by Ball Aerospace and Technologies Corp. for a seven-year mission. Five instruments aboard JPSS 1 will gather data on storms, clouds, fog, smoke plumes and snow and ice cover, measure atmospheric temperature and moisture content, and study the health of Earth's ozone layer.

The measurements will aid medium-range forecasts by feeding data into numerical computer models formulating three-to-seven-day weather outlooks.

The Delta 2 rocket's upper stage will deliver the JPSS 1 satellite into a 500-mile-high (800-kilometer) orbit, wh ere it will join — and eventually replace — the predecessor Suomi NPP weather craft launched in October 2011.

Built by Harris Corporation, the Cross-track Infrared Sounder (CrIS) is one of the top contributors to weather forecast accuracy out to seven days. CrIS produces detailed three-dimensional temperature, pressure, and moisture profiles from space. Understanding how each element varies with altitude is critical to producing an accurate weather forecast. This animation of CrIS data shows temperature at different altitudes as the earth spins.

CrIS captures data across more than 2,000 "slices" of the atmosphere from near Earth's surface up to around 30 kilometers, compared to only 19 slices by previous instruments. This allows CrIS to observe the vertical structure of the atmosphere in much finer detail than ever before. The first CrIS instrument operates on board the NOAA/NASA Suomi National Polar-orbiting Partnership (Suomi NPP) satellite which launched in 2011. The second instrument is ready to launch on NOAA's JPSS-1 satellite.

MiRaTA Satellite Overview

MiRaTA (Microwave Radiometer Technology Acceleration) is an Earth observation technology demonstration CubeSat mission developed at MIT Lincoln Lab to test a miniaturized multi-band microwave radiometer and compact GPS occultation payload that could build the foundation of a future CubeSat constellation for the collection of global weather data at very rapid revisit intervals.

The MiRaTA project is part of NASA's InVEST (In-Space Validation of Earth Science Technologies) Program aiming to develop and test small instruments and remote-sensing subsystems that can advance the current state of technology to enable relevant Earth science measurements via smaller satellite platforms. MiRaTA will validate a new ultra-compact and low-power microwave radiometer for the collection of atmospheric profiles, a GPS occultation receiver and antenna for tropospheric radio occultation sounding and a novel approach to radiometer calibration using GPS radio occultation measurements. The goal is to advance the technology readiness level of both components fr om TRL 5 to 7 at the conclusion of the mission.

(https://img.novosti-kosmonavtiki.ru/153220.jpg) (http://spaceflight101.com/jpss-1/wp-content/uploads/sites/190/2017/11/mirata8.jpg)
Image: MIT/LL

MiRaTA is the first ever implementation of co-located radiometer and occultation sounding and the first CubeSat implementation of temperature/humidity radiometric sounding and occultation sounding. The mission will not only validate multiple subsystem technologies but also demonstrate a new sensing technique that could dramatically enhance the capabilities of future weather and climate observatories. Shrinking an operational radiometer and GPS RO system to fit onto a nanosatellite platform furthermore enables new architectural approaches for low-cost, high-return missions in the field of operational meteorology.

The calibration approach developed for MiRaTA calls for a pitch up/down maneuver once per orbit to complete a radiometer pass and GPS occultation across overlapping volumes of the atmosphere through Earth's limb where sensitivity, calibration, and dynamic range are optimal. For an operational mission, this type of measurement will allow for an intra-satellite calibration approach no-longer relying on blackbodies and other calibration sources. For MiRaTA, concurrent radiometer and GPS RO data will be compared with ground-based radiosondes and other satellite observations to validate the measurements.

MiRaTA is a three-unit CubeSat, 10 x 10 x 34 centimeters in size with a mass of under 4.5 Kilograms, using a platform that builds on the MicroMAS (Micro-sized Microwave Atmospheric Satellite) though with a number of simplifications, e.g. eliminating active scanning mechanisms and reducing deployable structures to a pair of solar panels and a simple tape-spring UHF communications antenna. Per the instrument requirements, the radiometer resides on the nadir-facing panel of the satellite while the GPS antennas face toward zenith.

Electrical power is provided by two double deployed solar panels that are hinged on the zenith-pointed satellite panel and feed power to a 20 Watt-hour Li-Ion battery assembly. An EPS card conditions the power buses at 3.3, 5 and 12 Volts and provides bus protection with the overall EPS design calling for a typical energy requirement per orbit around 8.3 Watts and a 20% design margin at satellite end of life. The two solar panels can deliver a peak power of 24.8 Watts.

The attitude control system of the satellite consists of reaction wheels that are used to stabilize the 3U satellite bus and keep it in an Earth-pointing attitude for normal data collection and facilitate the once-per-orbit pitch maneuver for instrument cross-calibration.

Attitude determination is provided by a series of sensors – an Inertial Measurement Unit and magnetometer are used in the initial attitude acquisition and de-tumble before the satellite begins processing sun sensor data in a TRIAD navigation method with Earth horizon sensors in use for verification of the correct attitude for science operations.

Attitude actuation uses a combination of torque rods and reaction wheels integrated within the MAI-400 assembly provided by Maryland Aerospace. In addition to two Earth horizon sensors within MAI-400, the MiRaTA satellite hosts a third sensor to assist in the pitch-up maneuver.

The satellite motherboard is a standard CubeSat board provided by Pumpkin using a PIC24 microcontroller as flight computer that runs on Pumpkin's Salvo Real Time Operating System. The satellite uses CubeSat-Kit interfaces for the reaction wheels, communication system and mass memory while the PCB is used for the attitude sensors, motor controller and payload. Payload Data is stored in an SD card.

Communications are accomplished with a half-duplex L-3 Communications Cadet UHF Nanosatellite radio. Operating at a frequency of 450MHz for uplink, the system achieves a data rate of 9.6kbit/s with GFSK modulation and 19.2kbit/s with FEC. Downlink uses the 468MHz UHF frequency for low data volumes as the payload generates a data volume of about 19 kbit/s when operating.

The MiRaTA nanosatellite hosts two complete instrument systems: MWR – the Microwave Radiometer, a tri-band atmospheric sounder, and CTAGS – the Compact TEC (Total Electron Count)/Atmosphere GPS Sensor. Both are operated to allow cross-comparison and cross-calibration to validate a new approach for potential future exploitation.

A microwave radiometer observes the radiance of the atmosphere at microwave wavelengths that are detected by an antenna which uses support electronics to amplify and record the signals of given frequency bands. The detected power level for each frequency band is used to generate temperature and moisture profiles through the various regions of the atmosphere. Elements present in the atmosphere have different absorption spectra, allowing radiometers to observe different atmospheric constituents.

MWR Electronics Block Diagram – Image: MIT/LL

The MWR instrument is a passive microwave radiometer collecting co-registered observations over three frequency bands via two radiometer subsystems. Two scalar feed horns illuminate an offset parabolic reflector that yields pitch-plane-aligned beam widths of 1.25 and 5.0° for the G- and V-Band systems, respectively with a beam efficiency higher than 95. The system has been designed with scalability in mind, allowing the aperture to be enlarged for a 6U CubeSat mission

The first subsystems hosts the systems of the 52-58 GHz V-Band channel, comprising the V-Band front end, low-noise amplifier, mixer coupled to a 81.47 GHz Local Oscillator, intermediate frequency amplifier and a compact back-end to provide six channels with temperature weighting functions approximately uniformly distributed over the troposphere and lower stratosphere up to an altitude of 20 Kilometers.

The second subsystem builds the G-Band sensing system covering a pair of channels at 175-191 and 206-208 GHz with a front end operating between 175.3 and 208.4 GHz and subharmonic detection chain with a 91 GHz Local Oscillator and conventional intermediate frequency spectrometer and back end. Both MWR subsystems share a common redundant dielectric resonator oscillator with multiplication stages in each of the local chains to match the required frequencies.

The addition of the CTAGS instrument allows MiRaTA to combine the benefits of passive sounding and GPS Radio Occultation measurements to achieve highly accurate calibration with dense geospatial sampling. Benefits of using GPS RO are primarily found in the accuracy of measurements which easily achieves 0.1 K for vertical temperature profiles in the upper troposphere and lower stratosphere; however, GPSRO measurements have sparse geospatial coverage with daily measurements ranging between a few hundred and a few thousand while traditional microwave radiometers can conduct continuous measurements and easily achieve global coverage.

GPS Occultation Measurement – Image: Tyvak/NASA

The issue that arises for microwave instruments is an elaborate calibration requirement to ensure radiometric accuracy which, for typical missions, relies on internal blackbodies as a hot reference point and soundings of cold space as cold reference as well as solar irradiance and lunar calibration measurements. The combination of a radiometer and GPSRO instrument will allow a two-way calibration without Internal Calibration Targets which often drive the instrument design and add mass to the sensors.

GNSS occultation measurements for atmospheric and ionospheric measurements is a proven method for the acquisition of temperature, pressure and humidity profiles from high altitude to near-ground level. The science and methodology behind GNSS occultation measurements is well established and has been employed for many scientific projects as well as operational meteorology systems.

GPS operates a constellation of approximately 30 active satellites in six orbital planes, 20,000 Kilometers in altitude, transmitting different L-Band signals used for navigation and precise timing applications as well as a wide variety of other applications including meteorology. At least four satellites are simultaneously visible from any position on Earth, an observer in Low Earth Orbit will usually see 12 satellites at any time.

(https://img.novosti-kosmonavtiki.ru/153224.jpg) (http://spaceflight101.com/jpss-1/wp-content/uploads/sites/190/2017/11/VCIP5.jpg)
GPS Occultation – Image: Nanyang Technological University

Occultation measurements make use of the fact that Earth's atmosphere can alter the properties of a GPS signal to extract relevant meteorological parameters. The measurement is done by a satellite that sees its line of sight to a GPS satellite penetrate Earth's atmosphere as the GPS satellite either rises for sets from the receiver's vantage point.

CTAGS flown on MiRaTA is based on the successful CTECS (Compact Total Electron Content Sensor) hosted by the OSIRIS-3U CubeSat. The advanced system employs a more compact and capable GPS receiver and a high-gain patch antenna array to extend measurements from the ionosphere into the lower atmosphere, allowing CTAGS to collect ionospheric and atmospheric measurements down to at least 20 Kilometers in altitude. The instrument consists of four primary components: a multi-element antenna array, single patch antenna for precise orbit determination, low-noise amplification stage and a NovaTel OEM628 GPS receiver.

(https://img.novosti-kosmonavtiki.ru/153219.jpg) (http://spaceflight101.com/jpss-1/wp-content/uploads/sites/190/2017/11/mirata7.jpg)
GPS Receiver & Patch Antenna Segment – Image: MIT/LL

CTAGS combines multiple heritage CTECS antenna elements and the higher gain allows the instrument to remain locked on GPS satellites as they set behind the Earth's dense atmospheric layers for low-altitude measurements. The receiver can track up to 60 dual-frequency satellites at any time, allowing for simultaneous atmospheric, ionospheric, and navigation observations, utilizing the L1, L2 and L2c signals for refraction measurements from which the total electron content/atmospheric properties and their vertical profiles can be extracted. CTAGS makes measurements of the L1/L2 pseudorange and L1/L2/L2c phase, taking advantage of the satellite's relatively low orbit to measure a large amount of density above the satellite.

The calibration of radiometers has proven to be challenging even for flagship missions like the ATMS (Advanced Technology Microwave Sounder) on the NPP and JPSS satellites and the GMI (Microwave Imager) on GPM (Global Precipitation Mission). Research has shown that biases, despite high-fidelity calibration approaches, may be as high as 2 Kelvin.

(https://img.novosti-kosmonavtiki.ru/153214.jpg) (http://spaceflight101.com/jpss-1/wp-content/uploads/sites/190/2017/11/mirata10.jpg)
Image: MIT/LL

MiRaTA proposes a two-pronged calibration approach that promises much greater accuracy while reducing complexity and instrument size through the use of the combination of a noise diode for frequent calibration of the radiometer and the less-frequent GPSRO measurement as a through-the-antenna end-to-end calibration of the instrument and as cross-check for the noise diode to calibrate its accuracy and stability.

Noise diodes are used in the radiometer front end to inject a calibration signal into the radiometer with relatively low loss, though susceptible to signal drifts and not representing a complete through-the-antenna calibration. Furthermore, integrating noise diodes into the signal path requires a switch which adds signal losses that can be of significance when aiming for large-area coverage over short time scales.

(https://img.novosti-kosmonavtiki.ru/153217.jpg) (http://spaceflight101.com/jpss-1/wp-content/uploads/sites/190/2017/11/mirata4.jpg)
MiRaTA Operational Sequence – Image: MIT/LL

Operationally, the MiRaTA concept will be realized by slewing the spacecraft from a radiometer-nadir attitude to a 90-105-degree pitch angle and back so that the radiometer and GPSRO instrument can sound the same area of Earth's limb with very little time difference. The sequence will take between 22 and 32 minutes to complete and requires at least one or two GPS satellites to set behind the atmosphere, as seen by the CTAGS instrument.

The mission ground software is in charge of computing favorable opportunities by cross checking the satellite's orbital parameters, CTAGS and MWR look angles and relative geometry with GPS satellites to isolate opportunities wh ere the GPSRO and MWR fields overlap sufficiently – also taking into account onboard resources like power and reaction wheel saturation. These are then uplinked to the satellite as time-tagged command sequences and executed autonomously. Mission simulations predict two to three favorable opportunities to be available per day with overlaps of five to seven minutes.

The MiRaTA mission aims to collect at least 100 concurrent GPSRO and MWR measurements with a radiometric accuracy achieved through the new cross-calibration process matching that of the Joint Polar Satellite System (1.5K rms) down to 20 Kilometers (requirement) or 10 Kilometers (goal).

Buccaneer RRM

Project Buccaneer is a joint initiative of the University of New South Wales and the Australian Defence Science and Technology Group within the Department of Defence dedicated to the calibration of the Jindalee over-the-horizon radar network.

Image: DSTO

The Jindalee Operational Radar Network (JORN) is used by the Australian Defence Forces to observe air and sea activity north of Australia to distances of up to 4,000 Kilometers – including Java, Papua New Guinea and the Solomon Islands.

In practice, the radar has shown to be even more sensitive, capable of observing a single-engine Cessna taking off and landing at a distance of 2,600 Kilometers and observations of missile launches more than 5,500 Kilometers away have proven feasible. Further improving the system's sensitivity by a factor of ten is underway and will employ a space-based mission to conduct high-fidelity calibration.

The A$2 billion system consists of two active radar stations in Queensland with 90° coverage and Western Australia with 180° coverage to form an overlapping coverage cone to the north, a control center in South Australia, seven transponders and a dozen vertical ionosondes to deliver ionospheric measurements, and a research radar station in Northern Territory. JORN can be temporarily expanded to three stations using the Alice Springs radar.

Signals sent by the transmitters are bounced off by the ionosphere and the echoes recorded by receiving stations at sufficient distance to the transmitter to avoid interference. Moving objects are detected using the Doppler principle.

JORN uses frequencies of 5 to 30 MHz, much lower than conventional civilian and military microwave radars. To achieve high sensitivity in changing ionospheric conditions, the ionosonde network operated by JORN, plus additional DSTO stations, generate complete ionospheric maps at a refresh rate of under four minutes.

Project Buccaneer has the overall goal of deploying an advanced high-frequency receiver into orbit to provide performance calibration for JORN at different distances and varying ionospheric conditions to help improve the system's sensitivity. Given the complexities involved in a space mission, the project was baselined for a pair of flights – the Buccaneer Risk Mitigation Mission RRM and the operational Buccaneer flight around one year later. RRM primarily deals with the deployment and stability of the radar antenna.

Both Buccaneer satellite use a commercially-available 3U Satellite Platform (10 x 10 x 34 centimeters) from Pumpkin Inc. to provide electrical power generation via body-mounted solar cells and two deployable solar arrays, attitude determination and control via magnetic torquers with sufficient pointing control for the experiment, and housekeeping and payload communications.

The payload of the satellites is a high-frequency receiver optimized for the JORN frequencies and a HF antenna deploying from a purpose-built mechanism on the satellite's forward panel.

The bowtie antenna consists of commercially available spring steel measuring tape, allowing the individual antenna segments to be wound up for launch and deploy to their full extension using a self-driving deployment system to unwind the antenna arms. Each antenna section measures 1.73 meters from its tip to the satellite body and 3.46 from tip to tip, exceeding the satellite's body length by a factor of ten.

Extensive analysis was performed into the stability of the antenna system given the very thin and flexible nature of the material which can not support its own weight in a gravity environment but will be able to remain stable when being deployed in space. Analysis focused on a buckling failure of the antenna even in the small loads present in Low Earth Orbit due to aerodynamic drag in the upper atmosphere, solar radiation pressure or internal loads on the satellite.

BRRM Antenna Assembly – Image: DSTO

Chosen for Buccaneer is a commercial measuring tape 0.1 mm thick with a flattened width of 19 mm, a broadened cross section of 18 mm and a narrow-cross section of 2.5 mm when in its rigidized state. When deployed, the antenna will be in a stable equilibrium using the manufactured curvature of the tape to provide the stiffness needed to remain in a deployed state. For deployment, the strain energy within the tape will be used to deploy the antenna to full length with burn wires holding the system in its compressed state until deployment is commanded.

The Buccaneer RRM mission will employ a flight-like antenna subsystem but substitutes the HF receiver with an on-board camera to document the antenna deployment and its stability in the actual flight environment to eliminate risk for the operational mission. The flight will also provide a platform to conduct photometric experiments with the Falcon Telescope Network operated by the University of New South Wales for astrodynamics assessments.

JPSS-1 Mission – 1U CubeSat Secondary Payloads

MakerSat 0

Спойлер

MakerSat 0 is a 1U CubeSat designed at Northwest Nazarene University for a technology demonstration of a fully 3D printed satellite structure with a common power, control, computing, and radio communication architecture connected to four science boards that integrate into the platform in a modular manner to allow it to host payloads fr om different operators. Two demonstration launches are planned to qualify the MakerSat for operational use in hosting single-board payloads fr om commercial and educational operators.

Extending the MakerSat concept, designers foresee a capability of launching CubeSat components to the Space Station, manufacturing structural frames as needed using 3D printing and having ISS crew members assemble modular platform components and integrate them with single- or multi-board payloads on ISS for deployment.

(https://img.novosti-kosmonavtiki.ru/153211.jpg) (http://spaceflight101.com/jpss-1/wp-content/uploads/sites/190/2017/11/makersat4.jpg)
Image: Northwest Nazarene University

The MakerSat 0 satellite hosts science payloads looking into the degradation of different additively-manufactured polymers in orbit as a result of mass loss due to atomic oxygen, UV radiation, ionizing radiation and outgassing.

Structurally, the MakerSat design employs four polyetherimide (PEI) 3D printed rails that slide and snap together with six Printed Circuit Boards without the use of any tools, allowing the satellite to be put together in a period of minutes, also avoiding any free-floating small components that could pose a danger for in-space assembly of the satellite. Once the six PCBs are ingrated, the satellite platform can be powered up via a USB port and go through checkouts prior to deployment.

MakerSat 0 was manufactured by a Made In Space Additive Manufacturing Facility similar to that on the Space Station while MakerSat 1 will demonstrate the ISS-based assembly process.

The MakerSat platform comprises a central Hub that interfaces with the four Science Boards which reside on the back of the four solar side panels with the Hub itself facilitated on the bottom panel and the combined EPS, Comms and Onboard Computer package on the topmost panel. The Hub hosts a microcontroller to build the central interface for all CubeSat subsystems and also facilitates an Inertial Measurement Unit to provide attitude data in addition to the solar cells on all outer panels that can be used to determine the solar vector. The solar boards include cut-outs for any external sensors of the payloads, e.g. cameras.

(https://img.novosti-kosmonavtiki.ru/153209.jpg) (http://spaceflight101.com/jpss-1/wp-content/uploads/sites/190/2017/11/makersat1.jpg)
MakerSat Structure – Image: Northwest Nazarene University

The individual components (Hub, EPS/COMMS/OBC, solar panels and science boards are pre-assembled on Earth and fly to ISS in a low-vibration environment, protected by packaging inside an ISS cargo vehicle.

The central Hub concept was chosen to provide a single connection point for all satellite components and thus reduce the probability of assembly errors. It also allows for equal access to the satellite's resources for all four science payloads.

The Hub provides sequencing, control and data return to all four science boards, operated in a peer-to-peer design with the OBC/EPS wh ere the Hub is in charge of commanding the EPS to cycle power to the payloads according to their duty cycle. The Hub also offers additional computing power and memory for the science boards and collects all science data from the boards and prepares it for transmission to Earth via the COMMS section.

An 8-bit PIC microcontroller with extensive flight heritage serves as onboard computer and handles all payload operations as well as science board commanding. Power is generated by 28% Ultra-Triple-Junction solar cells with two cells in series per solar panel to deliver 4.7 V, 2 W from each board under full illumination. Four Li-Polymer batteries with a 4.4-Ah capacity at 7.4 V provide power storage. Attitude stabilization is accomplished with a simple solution using a permanent magnet to keep the satellite aligned with Earth's magnetic field.

MakerSat Hub – Image: Northwest Nazarene University

Communications are handled by an EyeStar Simplex radio to communicate through the GlobalStar satellite constellation and provide a 24/7 data downlink capability with near global coverage via 14 ground gateways from wh ere the downlinked data is uploaded to the Internet for access by the science teams. The EyeStar radio will transmit 18-byte satellite health packets with telemetry values such as temperature and bus voltage and 39-byte science data packets containing data from the science boards. The total data volume per day is expected to be around 50 to 100 kbyte/day, limited by the power budget and data rate costs. The Simplex radio will also allow insight into satellite status via a beacon signal should the Hub or combined OBC/EPS suffer a failure.

The science boards can either use I²C or SPI interfaces to communicate with the Hub and MakerSat also supports General Purpose Input/Output (GPIO) digital logic lines and serial communications. The Hub, based on the duty cycles for each science board, will cycle the 3.3 V power supplies of each of the boards to switch it on/off and it also isolates the I²C and SPI lines of boards that are inactive.

MakerSat 0 hosts two science boards for the Polymer Loss Experiment, an Imaging Board with an Earth observation camera, and a science board designed and built at Caldwell High School, Idaho.

(https://img.novosti-kosmonavtiki.ru/153212.jpg) (http://spaceflight101.com/jpss-1/wp-content/uploads/sites/190/2017/11/makersat5.jpg)
Polymer Loss Experiment – Image: Northwest Nazarene University

The Imaging Board Integrates a Commercial Off-The-Shelf imaging sensor integrated in the science board and viewing outside the satellite through a 32 x 9-millimeter port in the outer solar array panel. Images taken by the camera will be analyzed on board to discard any images that only show dark space and compression is completed using lightweight algorithms given the very limited memory on the satellite.

The Polymer Loss Experiment will subject samples of 3D printed polymers to mass loss measurements at regular intervals to track how the space environment (oxygen radicals, UV radiation, ionizing radiation, vacuum outgassing) degrades different polymer materials. The mass of the test objects is measured by placing the 3D printed polymers at the end of piezo-electric cantilevers and measuring the change in resonant vibrational frequency of each cantilever from which the mass at the end of the beam can be calculated.

MakerSat 0 features a slightly different design than the operational MakerSats due to it being launched conventionally and having to withstand the launch G and vibration environment. Therefore, it uses a more rigid structure to survive the launch forces but retains the electronics boards from the operational satellites.

The Eagle Sat Project was selected to fly under NASA's ELaNa program in 2013 as a primarily student-run extracurricular project. The satellite uses a conventional 1U CubeSat design with six stacked circuit boards inside the satellite hosting the various subsystems while the external side panels facilitate solar cells for power generation. The power system employs super capacitors for energy storage and communications are provided via UHF at 436MHz.

EagleSat hosts a pair of payloads, a GPS receiver to track the decay of the cube's orbit to provide information for decay and re-entry modeling. The primary science payload is a RAM memory stack to be monitored for space-induced bit flips with a solid state radiation detector providing information on the radiation environment experienced by the satellite.

Suomi National Polar-orbiting Partnership, formerly known as the NPOESS Preparatory Project, will serve as a bridge between the EOS satellites and the forthcoming series of Joint Polar Satellite System (JPSS) satellites. Suomi NPP represents a critical first step in building this next-generation satellite system. The JPSS satellites, previously called the National Polar-orbiting Operational Environmental Satellite System (NPOESS), will be developed by NASA for the National Oceanic and Atmospheric Administration (NOAA).

At launch time, JPSS-1 will weigh 5,025 pounds, so getting it from Earth to space will require quite an effort. Fortunately, we have a launch vehicle that's up to the task.

JPSS-1 will rocket into space into polar orbit aboard 128-foot Delta II 7920-10C rocket consisting of a booster stage, hypergolic second stage, nine solid rocket motors and a 10-foot diameter payload fairing. (Whew!)

The JPSS-1 launch will mark the 53rd Delta II mission for NASA and 154th launch since the rocket's first launch in 1989. Previous Delta II missions for NASA include the Spirit and Opportunity Mars rovers as well as Suomi NPP, the precursor to the next-generation polar-orbiting satellite in the JPSS series.

Weather satellites have traditionally been large, both in the effort needed to build them and in actual size. A NASA-funded CubeSat, called Microwave Radiometer Technology Acceleration (MiRaTA), which will be launched into Earth's orbit from the rocket carrying the next big U.S. weather satellite (NOAA's JPSS-1) into space, was designed to demonstrate that a small satellite can carry instrument technology that's capable of reducing the cost and size of future weather satellites and has the potential to routinely collect reliable weather data.

Weather satellites have traditionally been large, both in the effort needed to build them and in actual size. They can take several years to build and can be as big as a small school bus. But all of that could change in the future with the help of a shoebox-sized satellite that will start orbiting Earth later this month.

The NASA-funded CubeSat, called Microwave Radiometer Technology Acceleration (MiRaTA), will be launched into Earth's orbit from the rocket carrying the next big U.S. weather satellite (NOAA's JPSS-1) into space. MiRaTA is designed to demonstrate that a small satellite can carry instrument technology that's capable of reducing the cost and size of future weather satellites and has the potential to routinely collect reliable weather data.

Microwave radiometers are one of the workhorse instruments aboard today's weather satellites. These sensitive instruments measure radio frequency signals related to the thermal radiation emitted by atmospheric gases, such as molecular oxygen and water vapor, and also detect particles such as cloud ice. These data are key inputs for models that track storms and other weather events. Calibrating these radiometers is important for keeping them from drifting so their data can be used for accurate weather and climate models. Therefore, a calibration target is usually included in the satellite to help the radiometer maintain its accuracy.

Miniaturizing microwave radiometer instruments to fit on a CubeSat leads to the challenge of finding a calibration instrument that is not only accurate but also compact, said Kerri Cahoy, principal investigator for MiRaTA and an associate professor in the Department of Aeronautics and Astronautics at the Massachusetts Institute of Technology. "You don't have room for the bulky calibration targets that you would normally use on larger satellites," Cahoy said. "Microwave radiometer calibration targets on larger satellites can be the size of a toaster, but for CubeSats, it would have to be the size of a deck of cards."

(https://img.novosti-kosmonavtiki.ru/207710.jpg) (https://www.nasa.gov/sites/default/files/thumbnails/image/dsc_0623cropped11.jpg)
The Microwave Radiometer Technology Acceleration (MiRaTA) satellite, a 3U CubeSat, is shown with solar panels fully deployed, flanking the body of the spacecraft, which has a circular aperture at the top for the microwave radiometer antenna, used for atmospheric science measurements. There are also two small, thin tape-measure antennas on the top, used for UHF radio communication with the ground station.

Cahoy and her colleague William Blackwell, the microwave radiometer instrument lead at MIT Lincoln Laboratory, have come up with a solution based on a technique she studied in graduate school called radio occultation (RO), whereby radio signals received from GPS satellites in a higher orbit are used to measure the temperature of the same volume of atmosphere that the radiometer is viewing. The GPS-RO temperature measurement can then be used for calibrating the radiometer.

"In physics class, you learn that a pencil submerged in water looks like it's broken in half because light bends differently in the water than in the air," Cahoy said. "Radio waves are like light in that they refract when they go through changing densities of air, and we can use the magnitude of the refraction to calculate the temperature of the surrounding atmosphere with near-perfect accuracy and use this to calibrate a radiometer."

In 2012 NASA's In-Space Validation of Earth Science Technologies (InVEST) program issued a request for technology demonstration proposals, which prompted Blackwell and Cahoy, who was then teaching at MIT, put their theory to the test by offering a project to Cahoy's students in her sensors and instrumentation class to determine if the idea was feasible. When two students demonstrated through computer modeling that radio occultation could indeed function for radiometer calibration, Cahoy and Blackwell asked The Aerospace Corporation's Rebecca Bishop, who has developed GPS-RO receivers for CubeSats, to join the team. They then submitted a full proposal for MiRaTA to NASA, which gave the greenlight for funding in the spring of 2013.

Building MiRaTA was a team effort. Bishop modified an off-the-shelf, low-cost GPS receiver to make the radio occultation measurements for calibration; MIT Lincoln Laboratory and University of Massachusetts Amherst applied their engineering skills to further miniaturize the microwave radiometer; and Cahoy and her student team, guided by expert mentors at MIT Lincoln, built the satellite that would house everything.

"Building a CubeSat can be hard because you have to put batteries, a radio, a computer, your instruments, wheels that you spin to tip and turn your satellite, and folded solar panels and antennas all into a very small space," Cahoy said. "And you're using the space equivalent of scotch tape and super glue to constrain this mess of wires and connectors and get it into its housing.

"But," Cahoy added, "the hard work will really pay off in great science data if it all goes as planned."

In the best-case scenario, three weeks after launch MiRaTA will be fully operational, and within three months the team will have obtained validation data from both the radiometer and the GPS receiver. The big goal for the mission—declaring the technology demonstration a success—would be confirmed a bit farther down the road, at least half a year away, following the data analysis.

If MiRaTA's technology validation is successful, Cahoy said she envisions an eventual constellation of these CubeSats orbiting the entire Earth, taking snapshots of the state of the atmosphere and weather every 15 minutes—frequent enough to track storms, from blizzards to hurricanes, in real time. "Our goal is to have our radiometers perform just as well as those on current weather satellites and be able to provide the kind of data that helps agencies and people in the path of a natural disaster prepare early and wisely," she said.

"This is a very exciting mission as it will be the first on-orbit demonstration of an all-weather, three-frequency radiometer CubeSat using atmospheric GPS-RO-based calibration," said NASA Jet Propulsion Laboratory's Charles Norton, a program associate in NASA's Earth Science Technology Office (ESTO) and the task manager for MiRaTA. "It's a true testament to the creativity and innovation of the teams involved that they're advancing measurement technologies for future small satellite constellation missions," he said, while adding that Utah State University's Space Dynamics Laboratory and NASA Wallops Flight Facility are supporting ground station and mission operations for the CubeSat.

MiRaTA and other Earth science InVEST missions are funded and managed by NASA's ESTO program in NASA's Earth Science Division. ESTO supports technologists at NASA centers, industry and academia to develop, refine and demonstrate new methods for observing Earth from space, from information systems to new components and instruments.

Small satellites (https://www.nasa.gov/smallsats), including CubeSats, are playing an increasingly larger role in exploration, technology demonstration, scientific research and educational investigations at NASA, including: planetary space exploration; Earth observations; fundamental Earth and space science; and developing precursor science instruments like cutting-edge laser communications, satellite-to-satellite communications and autonomous movement capabilities.

Ready for Launch, Ball Aerospace Completes Prep for JPSS-1 Satellite

BOULDER, Colo., Nov. 9, 2017 — NOAA's Joint Polar Satellite System-1 (JPSS-1) is encapsulated inside the fairing (nose cone) of a United Launch Alliance Delta II launch vehicle ready for lift off fr om Space Launch Complex-2W at Vandenberg Air Force Base, California, on November 14, 2017 at 1:47 a.m., PST. JPSS-1 is a collaborative effort between NOAA and NASA.

"The JPSS-1 bus is based on our Ball Configurable Platform (http://www.ball.com/aerospace/markets-capabilities/markets/commercial/custom-spacecraft) 2000, a proven, agile spacecraft, which has 50 years of on-orbit operations and is designed for cost-effective, remote sensing applications," said Alex Chernushin, JPSS-1 Program Manager, Ball Aerospace. "JPSS-1 is the twelfth spacecraft built on this core architecture, including the Suomi National Polar-orbiting Partnership (Suomi NPP) spacecraft launched in 2011."

The sensor capabilities for JPSS-1 have similar capabilities to those of Suomi NPP: the Advanced Technology Microwave Sounder (ATMS) and the Clouds and the Earth's Radiant Energy System (CERES), built by Northrop Grumman; the Cross-track Infrared Sounder (CrIS), built by Harris; the Ozone Mapping and Profiler Suite (http://www.ball.com/aerospace/programs/omps)-Nadir (OMPS-N), built by Ball; and the Visible Infrared Imaging Radiometer Suite (VIIRS), built by Raytheon.

Collecting data on our Earth's atmosphere, oceans and land surface, JPSS-1, or NOAA-20 as it will be known once it reaches its polar orbit, will feed NOAA's National Weather Service models, giving forecasters the actionable environment intelligence they need to monitor and predict weather patterns with greater speed and accuracy. This will enable emergency managers to make timely decisions to protect lives and property, including ordering effective evacuations five to seven days in advance.

In addition, the data from JPSS-1 gives troops a competitive advantage on the battlefield; allows transportation industry to prepare and move resources, protecting local economies; and provides citizens with more accurate weather forecasts to plan their day.

The JPSS-1 spacecraft was built and integrated by Ball Aerospace in Boulder, Colorado, wh ere the business has operated for more than 60 years and continues to invest heavily in its capabilities and the community. Since expanding its Fisher Manufacturing Complex by 82,000 square-feet in 2014, Ball is installing a new, 1,200 square-foot thermal vacuum chamber to support the continued demand for large spacecraft. Ball is also growing in nearby Westminster, Colorado with a 145,000 square-foot addition to its Aerospace Manufacturing Center currently under construction. Ball employs more than 3,000 people across the U.S., with 2,500 based in Colorado. The business has hired more than 600 new employees during the past two years to meet growing customer needs.

November 13, 2017 (http://spaceflight101.com/penultimate-delta-ii-rocket-stands-ready-for-jpss-1-launch/)

The penultimate Delta II rocket stands ready for an early morning liftoff from California's Vandenberg Air Force Base on Tuesday with the first operational satellite of the Joint Polar Satellite System, the next-generation of low-orbiting weather satellites operated by NASA and NOAA.

Liftoff has to occur within a 62-second launch window opening at 9:47:03 UTC, 1:47 a.m. local time to position the satellite opposite its predecessor, the six-year old Suomi NPP, in order to maximize coverage between the two satellites. Delta II also has five small CubeSats riding shotgun, aiming for deployment after the primary payload is on its way.

The venerable Delta II rocket – once the most-flown U.S. launch vehicle – is on the verge of closing out a remarkable career of almost three decades, debuting back in 1989 and keeping up an impressive record of 151 successful launches out of 153 missions. JPSS-1 is hoping to become Delta II's 99th consecutive launch success and the final Delta II mission set for next year with NASA's ICESat-II could send the rocket into retirement with an unprecedented 100 successes in a row.

Approaching its retirement, Delta II stepped down its launch rate over the last decade, also due to Delta IV and Atlas V reaching their full operational capabilities. Delta II's Cape Canaveral launch pad at SLC-17 saw its final launch in 2011 on the GRAIL mission to study the Moon's gravity with all remaining launches planned from Vandenberg's SLC-2W. Over the course of its career, Delta II lifted a number of notable payloads such as the Dawn spacecraft still actively collecting data in orbit around dwarf planet Ceres, the Kepler space telescope on the hunt for Exoplanets, the MESSENGER probe that explored Mercury, and a number of Mars missions including Pathfinder, Odyssey, Phoenix and, of course, the two Mars Exploration Rovers Spirit and Opportunity.

Delta II has also contributed to Earth Science and is spending the last missions of its career in support of science and operational missions focused on our planet. Delta II launched the Suomi NPP satellite in 2011 to patch a gap between NOAA's Polar Operational Environmental Satellites and JPSS. In 2014, Delta II launched the second Orbiting Carbon Observatory to study Earth's carbon cycle and the most recent Delta II delivered the Soil Moisture Active/Passive spacecraft in January 2015.

Gearing up for the inaugural launch for the Joint Polar Satellite System, Delta II was delivered to Vandenberg in 2015 and 2016 before starting assembly at SLC-2W on July 12, 2016 when the RS-27-powered first stage was installed on the pad followed by the installation of the large Interstage Assembly the next day. What followed over the next several months was the installation of nine Solid Rocket Motors around the first stage and hoisting the Delta-K second stage to take its place atop the vehicle.

JPSS-1 was delivered to Vandenberg Air Force Base on September 1s, 2017 after slipping from an initial launch target in March. The Joint Polar Satellite System finds its roots in the National Polar-Orbiting Operational Environmental Satellite Program (NPOESS) that was initiated in 1994 when efforts began to consolidate the mostly separate weather satellite programs of NASA/NOAA and the U.S. Air Force.

Under NPOESS, NOAA was to be responsible for placing satellites into afternoon orbits while the Air Force's Defence Weather Satellite System would be operated in a morning orbit with additional data available through data sharing agreements with Europe's MetOp program operating in a mid-morning orbit. However, the tri-agency effort ended in a fiasco – overrunning its original budget by a factor of two, encountering technical issues and having to undergo several re-structuring efforts since executing the program between three agencies with different objectives and long-standing acquisition procedures proved extremely difficult.

The White House hit the emergency brake in 2010 when the programs were again split up with NASA and NOAA's Joint Polar Satellite System in the afternoon orbit and data from Europe's EUMETSAT for morning orbit coverage. The Air Force's military weather satellite program, called the Defence Meteorological Satellite Program, is expected to continue delivering data into the early 2020s given the recent decision to scrap the leftover DMSP-20 satellite. What comes after is uncertain and the Air Force is expecting to enter an extended gap in its own capability to acquire data and will have to rely on inputs from the civilian satellites and international cooperation.

Transitioning into JPSS, NASA and NOAA managed to remain on budget and schedule overruns were kept to half a year due to instrument-related complications. Current plans call for a pair of JPSS missions, JPSS-1 launching this week, and JPSS-2 in 2022 to sustain operations through 2028 when JPSS follow-on satellites or a new program of its own would begin operations. JPSS-1 is a close copy of the Suomi NPP satellite, built by Ball Aerospace, while JPSS-2 will be based on a platform provided by Orbital ATK.

JPSS-1 is based on the BCP-2000 satellite platform and has a launch mass of 2,540 Kilograms, standing 4.2 meters tall and hosting over 450 Kilograms in payload mass for its five instruments. The satellite will communicate through a number of ground stations as well as the Tracking and Data Relay Satellite System to enable a fast data pipeline with a typical acquisition to product turnaround of under 85 minutes to allow operational application of data provided by the satellites in weather now- and forecasting.

JPSS-1 collects visible and infrared imagery for day-and-night cloud monitoring, fire and volcano detection as well as aerosol monitoring using the Visible and Infrared Imaging Radiometer Suite that covers 22 spectral channels and delivers imagery at resolutions between 0.26 and 1.6 Kilometers across a 3,040-Kilometer ground swath to achieve daily global coverage for daytime imagery and twice-daily coverage for specialized day-and-night-band products. The other critical meteorology instrument on JPSS-1 is the Advanced Technology Microwave Sounder, a cross-track scanning instrument sensitive in 22 frequency bands to extract atmospheric profiles of temperature and humidity with one-Kilometer layers from the surface to an altitude of up to 45 Kilometers.

The Cross-Track Infrared Sounder has proven to be an extremely valuable addition to a weather forecaster's data inventory, collecting spectral imagery in 1,305 channels to refine vertical profiles of temperature accurate to 1K, 1% for atmospheric pressure and 20% for humidity for 14 x 14 x 1-Kilometer sample cells from the surface to the top of the atmosphere.

The remaining two instruments on JPSS-1 are the Ozone Mapping and Profiler Suite, delivering data valuable to the scientific community tracking ozone hole recovery and operational weather forecasters for UV index predictions, and CERES (Clouds and Earth's Radiant Energy System) providing continuation of one of the most-critical climate variables for long-term climate change studies.

JPSS-1 took its position atop the Delta II rocket on October 24 for encapsulation in the protective payload fairing followed by a series of integrated tests to verify the launch vehicle was ready to support its mission. The Flight Readiness Review for the satellite side was clean, but a four-day delay from the original November 10 target was necessitated by a faulty battery on the Delta II booster that required replacement and re-tests for a re-aligned launch target of November 14 with a 70% chance of favorable weather conditions for the brief nighttime window.

Flying in the 7920 configuration, Delta II employs the standard two-stage stack with a Thor/Delta XLT first stage and Delta-K second stage plus nine GEM-40 Boosters, marking the final nine-booster Delta II rocket to fly since ICESat-II will use the 7420 configuration with four SRMs. Delta II 7920-10C stands 38.9 meters tall with a core diameter of 2.44 meters and a launch mass of 228 metric tons, capable of placing three metric tons into Sun Synchronous Orbit.

The first stage of the Delta II is 26.1 meters long with a launch mass of 101,800 Kilograms including 96,120kg of Kerosene and Liquid Oxygen propellants. It is powered by a single RS-27A main engine delivering 1,054kN of vacuum thrust with engine gimbaling used to provide pitch and yaw control. Two 4.4kN LR-101 sustainer engines are used for roll control.

Each of the GEM-40 boosters stands 11 meters tall and is 1.03 meters in diameter, loaded with 11,800kg of solid propellant to deliver an average thrust of 499 Kilonewtons over a burn of 63 seconds. Six of the boosters will be fired up to lift the vehicle off the ground while the remaining three will be ignited upon burnout of the first set.

The Delta-K stage is six meters long and hidden inside the Interstage Assembly and Payload Fairing, holding six metric tons of Aerozine-50 and Nitrogen Tetroxide, a self-igniting propellant combination consumed by a 43.4kN AJ-10-118K engine. Delta II is topped by a three-meter diameter, 8.5-meter long payload fairing providing protection to the JPSS-1 satellite.

Final preparations for Tuesday morning's launch will be underway on Monday and include filling the first stage with its dose of 29,600 Kilograms of Rocket Propellant 1 before completing final close outs of the rocket and retracting the Mobile Service Tower, planned for around four in the afternoon, local time. This will be followed by final close outs of the pad ahead of evacuation of the launch zone for the initiation of the Launch Checklist.

Four hours before the planned T-0 time, the launch team will report to console as the Countdown Clock is initiated at T-2 hours and 30 minutes, starting with a 60-minute built in hold. This countdown hold allows teams to complete setup tasks such as communication checks between the individual launch support stations and the preparation of ground systems for upcoming countdown operations.

At T-2 hours 30 minutes and counting, the RIFCA, Delta II's primary flight controller, will be activated for pre-launch checkouts and software load. Helium and Nitrogen system pressurization is expected to begin around the same time and teams will put the Delta II through a series of electrical, communication system, Flight Termination System and propulsion system checkouts.

Starting at L-2 Hours, the launch team will go through polling for a GO/No GO for Liquid Oxygen loading – the only propellant component that has to be loaded during the countdown as RP-1 and second stage propellants will already be on board.

LOX load starts at L-1 hour 45 minutes, beginning with the pressurization and chilldown of transfer lines and the 1st stage tank before the -183°C LOX starts flowing into the vehicle. It takes about 30 minutes for LOX to be loaded to the 100% level to enable a test of the first stage propellant system – cycling the various valves and pressurizing the LOX tank to confirm its integrity. When the test is complete, Liquid Oxygen will be dumped to the 95% level.

Shortly after LOX load completion, Delta II will undergo hydraulic system activation and pressurization for pre-flight testing of the Thrust Vector Control System with gimbal motions on the first stage main engine and the two sustainer engines. Open Loop Testing of the Flight Termination System is finished 50 minutes before launch and a final round of communication checks with Delta II will be completed afterwards.

Helium and nitrogen will be topped-off as the countdown enters a planned built-in hold at T-15 minutes (L-45min). When the countdown resumes at L-25 minutes, Range Safety Checks will commence and a refined version of the flight software will be loaded into RIFCA based on the latest measurements of conditions in the upper atmosphere. LOX will enter topping to 99% at L-17 minutes.

Entering the final built-in hold at T-4 minutes, the launch team has ten minutes to complete the final polls for the Automated Countdown and configure JPSS-1 for launch by switching to onboard battery power.

Kicking off its automated countdown sequence at T-4 minutes, Delta II will begin arming its Flight Termination System and switch both stages to internal power followed by arming of igniters and separation pyros. Three minutes before launch, the RP-1 tank of the first stage pressurizes to flight level and the fuel umbilical is purged; pressurization of the LOX tank starts at T-2 minutes as the tank finishes topping at 100%.

A final verification of hydraulic pressures occurs at T-90 seconds and the Western Range will provide a GREEN status for launch. From T-1 minute, Delta II will be in control of the countdown, working towards arming of the ignition system at T-10 seconds, considered the hands-off point for manual aborts.

Three seconds ahead of liftoff, the RS-27A main engine ignites, soaring up to its full thrust of 90,750 Kilogram-force. When the engine reaches operational conditions, Delta II issues the command to ignite six of its Solid Rocket Motors to soar off the pad.

Jumping off the ground with a thrust of 480 metric-ton-force, Delta II will rise vertically for less than ten seconds before initiating its pitch and roll maneuver as the boosters reach their maximum operating pressure before entering a planned decline for the MaxQ period. Speeding due south, Delta II will reach the speed of sound 33 seconds after lifting off with Maximum Dynamic Pressure coming 15 seconds later as the vehicle cuts through the dense atmospheric layers.

>> Launch Profile (http://spaceflight101.com/jpss-1/flight-profile/)

The six ground-lit motors will burn out 63 seconds after launch and Delta II will fire up its three remaining boosters to continue towards orbit with a total thrust of 304 metric-ton-force.

To ensure a safe water impact point, Delta II will carry the dead weight of the spent ground-lits until one minute and 26 seconds into the flight. For the air-lits, burnout at T+2:06 will be followed five seconds later by jettison.

Having shed all nine boosters, Delta II will continue firing its RS-27A engine at a nominal vacuum thrust of 107,500 Kilogram-force, passing ten times the speed of sound three minutes into the flight. MECO – Main Engine Cutoff on the RS-27A will occur four minutes and 23.4 seconds into the flight followed four seconds later by VECO, shutdown on the twin LR-101 vernier engines. Stage separation occurs after another four seconds and the hypergolic-fueled AJ-10 engine will light up four minutes and 36.9 seconds into the flight to push the stack into orbit with a thrust of 4,300-Kilogram-force.

Delta II will jettison its payload fairing just four seconds into the second stage burn, revealing the JPSS-1 satellite for the rest of its journey, initially aiming for a slightly elliptical Parking Orbit peaking 830 Kilometers in altitude via a second stage burn of six minutes and 1.3 seconds. Next will be a passive coast phase of 40 minutes and 12 seconds to allow the vehicle to reach the high point of the Parking Orbit so that the second stage can circularize the orbit via a brief, 24-second burn starting 50 minutes and 50 seconds into flight to deliver JPSS-1 to a circular orbit of 830 Kilometers, inclined 98.7 degrees.

Separation of the JPSS-1 satellite is planned 57 minutes and 30 seconds after launch into an orbit separated by 50 minutes to the NPP satellite to establish a two-satellite constellation with optimized revisit characteristics to make the most of the overlap period between the two missions.

Having sent its primary payload on the way, Delta-K is set for a 10.2-second burn 75 minutes into the flight to lower its orbit for the separation of five CubeSats flying under NASA's ELaNa program. Deployment of the CubeSats will begin 81 minutes into the flight with three deployment events spaced by 100 seconds before the Delta upper stage fires up a fourth time at T+1 hour and 51 minutes on a 41-second deorbit maneuver that will take the stage to an ocean impact two hours and 11 minutes into the flight.

Today is "L-1" — one day remaining until the planned launch of a United Launch Alliance Delta II rocket carrying NOAA's Joint Polar Satellite System-1. Liftoff is scheduled for 1:47 a.m. PST (4:47 a.m. EST) Tuesday fr om Space Launch Complex 2 at California's Vandenberg Air Force Base.

The gantry-like tower at the launch site will be rolled back later today prior to the start of countdown activities. Live countdown coverage here on the JPSS-1 Launch Blog and on NASA TV will begin Tuesday at 1:15 a.m. PST (4:15 a.m. EST).

Meteorologists with the U.S. Air Force's 30th Weather Squadron have issued the L-1 Day forecast. The primary weather concern is ground winds that may equal or exceed the 26-knot lim it. Overall, the forecast predicts a 70 percent chance of favorable conditions at launch time.

United Launch Alliance's next-to-last Delta 2 rocket is set for liftoff from Vandenberg Air Force Base in California at 1:47 a.m. PST (4:47 a.m. EST; 0947 GMT) Tuesday with the JPSS 1 weather satellite, the first in a new line of polar-orbiting meteorological observatories for NOAA.

The 128-foot-tall (39-meter) rocket is sitting on its launch pad at Space Launch Complex 2-West. There is a 66-second launch window available Tuesday to allow the JPSS 1 satellite to enter an orbit synced with the Suomi-NPP weather spacecraft already in orbit.

Спойлер

The $1.6 billion JPSS 1 mission is the first satellite in NOAA's new-generation Joint Polar Satellite System, a fleet of four weather observatories developed to extend the weather agency's polar-orbiting program through 2038.

"These are exciting times for NOAA," said Ajay Mehta, acting director for systems in NOAA's satellite and information service.

The first in a new generation of geostationary satellites, named GOES-R before launch and since renamed GOES-16, lifted off from Cape Canaveral last November.

"(Now) we're going to be launching NOAA's JPSS 1, the first in a series of four highly advanced polar-orbiting satellites that will improve the accuracy and timeliness of NOAA's numerical weather prediction models and ultimately its weather forecasts," Mehta said.

ULA and NASA officials held a launch readiness review yesterday, clearing the Delta 2 rocket for final countdown preparations.

The mobile gantry at the Vandenberg launch pad will be wheeled back to launch position this afternoon in preparation for the start of the countdown overnight.

JPSS-1 to Provide More Accurate Environmental Forecasts

By Bob Granath
NASA's Kennedy Space Center, Florida

Editor's note: The JPSS-1 launch is now targeted for 1:47 a.m. PST (4:47 a.m. EST) on Tuesday, Nov. 14 (https://www.nasa.gov/press-release/jpss-1-now-scheduled-for-nov-14).

NASA is preparing to launch the Joint Polar Satellite System (http://www.jpss.noaa.gov/)-1, or JPSS-1, satellite on behalf of the National Oceanic and Atmospheric Administration (NOAA) to provide essential data for timely and accurate weather forecasts and for tracking environmental events such as forest fires and droughts.

Спойлер

JPSS-1 is the first in NOAA's series of four, next-generation operational environmental satellites designed to circle the Earth in a polar orbit. The JPSS program is a partnership between NOAA and NASA that will oversee all the satellites in the JPSS series. NOAA funds and manages the program, operations and data products. NASA develops and builds the instruments, spacecraft and ground system and launches the satellites for NOAA.

The mission is scheduled to begin at 4:47 a.m. EST (1:47 a.m. PST), Nov. 10, 2017, with JPSS-1 atop a United Launch Alliance (ULA) Delta II (https://www.nasa.gov/centers/kennedy/launchingrockets/delta-II-definitions.html) rocket lifting off from Space Launch Complex 2 (SLC-2) at Vandenberg Air Force Base in California.

Built by Ball Aerospace of Boulder, Colorado, the satellite will pass over the equator about 14 times each day, covering the globe twice every 24 hours. As it works, JPSS-1 will gather measurements of atmospheric, terrestrial and oceanic conditions, including sea and land surface temperatures, vegetation, clouds, rainfall, snow and ice cover, fire locations, atmospheric temperature, water vapor and ozone.

With these varied observations, JPSS will give environmental experts more accurate warnings in advance of hurricanes, tornadoes and blizzards. During its planned 10-years in orbit, JPSS-1 also will aid in assessing hazards such as droughts, forest fires, poor air quality and harmful coastal waters.

Preparations for the launch JPSS-1 rocket have been underway for more than a year. The first stage of the Delta II rocket arrived at Vandenberg's NASA Hangar 836 on April 4, 2016. Later in the month, the Delta II interstage and second stage also reached the West Coast launch site.

On July 12, 2016, the first stage of the ULA Delta II rocket was transported to SLC-2 at Vandenberg and positioned on the launch pad. The rocket's second stage was hoisted into the pad's gantry on April 11, 2017, and mounted atop the first stage of the rocket.

The JPSS-1 satellite arrived at Vandenberg on Sept. 1, 2017, for preflight preparations in the Astrotech Processing Facility. Following checkouts, the spacecraft was encapsulated in its payload fairing and moved to SLC-2 and mounted atop the Delta II rocket.

JPSS-1 will follow the joint NOAA/NASA Suomi National Polar-orbiting Partnership (https://www.nasa.gov/mission_pages/NPP/main/index.html), which was launched in 2011. Originally planned as a research and risk-reduction mission in the JPSS series, NOAA has been using Suomi NPP as its primary operational satellite for global weather observations since May 2014.

After it reaches orbit 512 miles above the Earth, JPSS-1 will be known as NOAA-20. Future satellites planned for the JPSS constellation include JPSS-2, scheduled for launch in 2021, JPSS-3 in 2026 and JPSS-4 in 2031. The series of four JPSS satellites are expected to span 20 years.

The U.S. government will make data from the JPSS system available to domestic and international users in support of U.S. commitments to the Global Earth Observation System of Systems (GEOSS).

The mobile service tower at Space Launch Complex 2-West was rolled away from the Delta 2 rocket and into launch position a few hours ago, setting the stage for an overnight countdown targeting liftoff at 1:47:02 a.m. PST (4:47:02 a.m. EST; 0947:02 GMT).

Спойлер

The moveable gantry, painted in blue-green to match the Delta 2, stands 177 feet (54 meters) tall and was used to assemble the launch vehicle and hoist the JPSS 1 spacecraft atop the rocket. It also houses a climate-controlled clean room for the satellite payload and protects the Delta 2 launcher from weather conditions at the seaside launch complex.

The countdown will come out of a built-in hold at T-minus 150 minutes at 10:47 p.m. PST (1:47 a.m. EST). A few minutes later, the Delta 2 launch team at Vandenberg will begin activating the rocket's guidance computer, followed by the start of propellant loading in the rocket's first stage.

The Delta 2's upper stage was filled with its mix of Aerozine 50 and nitrogen tetroxide propellants earlier in the launch campaign, and the nine strap-on boosters have their solid fuel pre-packed before attachment to the base of the rocket.

The official "go" has been given to start Delta II first stage liquid oxygen loading right on time today.

Цитировать11/14/2017 11:05

The Delta 2's first stage is now being loaded with cryogenic liquid oxygen chilled to minus 298 degrees Fahrenheit. The super-cold oxidizer is flowing from a 28,000-gallon storage tank at Space Launch Complex 2 into the Delta 2 rocket through plumbing at the base of the first stage.

The first stage's Aerojet Rocketdyne RS-27A main engine will consume the liquid oxygen with the RP-1 kerosene already pumped into the vehicle.

November 14, 2017 (https://spaceflightnow.com/2017/11/) Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

A Delta 2 rocket boosted by nine strap-on motors and two liquid-fueled stages will launch NOAA's JPSS 1 weather satellite into a 511-mile-high (822-kilometer) orbit following liftoff from Vandenberg Air Force Base, California.

Спойлер

https://www.youtube.com/watch?v=tLkbdYZyf1c (https://www.youtube.com/watch?v=tLkbdYZyf1c)

It will take 57-and-a-half minutes to deliver the JPSS 1 satellite to orbit from liftoff until spacecraft separation.

Launch is set for 1:47:02 a.m. PST (4:47:02 a.m. EST; 0947:02 GMT) from Space Launch Complex 2-West at Vandenberg.

The command to start the Delta 2's first stage RS-27A main engine is set for T-minus 2.7 seconds. After passing a computer health check, the six of the Delta 2's nine strap-on solid rocket boosters will ignite to send the launcher south from Vandenberg, following an arcing trajectory over the Pacific Ocean bound for polar orbit.

The RS-27A engine, manufactured by Aerojet Rocketdyne, will generate around 200,000 pounds of thrust at liftoff, consuming a mix of RP-1 kerosene and liquid oxygen. Each 40-inch-diameter (1-meter) booster ramps up to 145,000 pounds of thrust in vacuum.

The Delta 2 will surpass the speed of sound in 32 seconds and reach the phase of flight with maximum aerodynamic pressure at approximately T+plus 48 seconds. The six ground-lit boosters will burn for about 63 seconds, and three air-lit boosters will ignite around two seconds later to continue the climb into space.

The six burned-out motors will release in sets of three from the Delta 2 at about T+plus 1 minute, 26 seconds, jettisoning once the launcher is clear of offshore oil rigs. The other three boosters will consume their pre-packed solid propellants before separating to fall into the Pacific Ocean at T+plus 2 minutes, 12 seconds.

The Delta 2's main engine will continue firing until T+plus 4 minutes, 23 seconds. Seven seconds later, the rocket's first stage will detach, giving way to the upper stage's AJ10-118K engine to ignite at T+plus 4 minutes, 37 seconds.

Separation of the launcher's composite nose fairing is scheduled for T+plus 4 minutes, 41 seconds, once the Delta 2 is out of the lower atmosphere, exposing the JPSS 1 satellite to space for the first time.

Burning a blend of Aerozine 50 and nitrogen tetroxide storable liquid propellants, the second stage engine will fire until T+plus 10 minutes, 38 seconds, to place the JPSS 1 spacecraft in a preliminary egg-shaped elliptical orbit.

After coasting over Antarctica, the AJ10-118K engine will reignite at T+plus 50 minutes, 50 seconds. The 24-second burn will circularize the upper stage's orbit at an altitude of approximately 511 miles (822 kilometers) and an inclination of 98.7 degrees for deployment of the JPSS 1 weather satellite at T+plus 57 minutes, 30 seconds.

A third upper stage maneuver at T+plus 1 hour, 15 minutes, will last for 10 seconds to fine-tune the orbit for release of five CubeSat secondary payloads sponsored by NASA and developed by universities and institutions in Arizona, Idaho, Massachusetts, Tennessee and Australia.

The CubeSats will pop out of their launch containers beginning at T+plus 1 hour, 21 minutes, 40 seconds.

One more second stage firing will de-orbit the rocket to burn up in Earth's atmosphere.

The liquid oxygen tank on the Delta 2 rocket's first stage is now full. Liquid oxygen will continue flowing into the tank throughout the countdown to replace the super-cold oxidizer as it naturally boils away.

With the completion of liquid oxygen tanking, the Delta 2 rocket now stands fully fueled for launch with the JPSS 1 weather satellite at 1:47:35 a.m. PST (4:47:35 a.m. EST; 0947:35 GMT) from Vandenberg Air Force Base, California. RP-1 fuel was loaded into the first stage earlier in the countdown, and the second stage received its blend of Aerozine 50 and nitrogen tetroxide hypergolic propellants earlier in the launch campaign. The nine solid rocket boosters came with their propellants pre-packed.

ULA's Delta II rocket was forced to abandon a nighttime launch attempt fr om California in the early hours on Tuesday due to a technical issue with the rocket's second stage engine actuator as well as a fouled range with boasts in the offshore hazard area wh ere the vehicle's ground-lit boosters were expected to impact. Liftoff with the JPSS-1 satellite has been rescheduled for 9:47:02 UTC on Wednesday, the opening of a brief window.

The second-to-last Delta II rocket to take flight was revealed atop its SLC-2W launch pad at Vandenberg Air Force Base Monday afternoon when the Mobile Service Tower retracted to its launch position to mark the start of an overnight countdown operation. A picturesque sunset behind the 39-meter tall rocket followed by the typical nighttime fog moving in over Vandenberg set the stage for the penultimate Delta II mission, approaching the end of a three-decade career next year.

With the complex cleared by all personnel, countdown operations formally began with an hour-long hold at the T-2 hour and 30-minute mark before teams pressed into activation of the rocket's avionics for a detailed set of checkouts. Delta II received its dose of nearly 30 metric tons of Rocket Propellant 1 before clocks hit the T-2-hour mark and launch controllers cleared the vehicle to load 67 metric tons of Liquid Oxygen oxidizer.

Delta II stood fully fueled atop its launch pad as oxygen naturally boiled off and was replenished on its first stage while the second stage had been sitting fully fueled for a number of days given its use of storable propellants. The vehicle entered a series of slew checks on its RS-27A first stage main engine, two sustainer engines on the first stage and the AJ-10 on the Delta-K second stage. No issues were reported at that point and final countdown operations commenced with the upload of the appropriate trajectory file into the rocket's computers while the 2.5-metric-ton JPSS-1 satellite made its transition to battery power.

The countdown held at T-4 minutes and all appeared to be ready for liftoff until two problems were reported to the launch team. The first was a RED condition on the Western Range due to boats straying into the offshore hazard area and the second was a red line limit tripped for the yaw actuator current on the second stage's thrust vector control system, occurring just as the team was pressing into final polling.

Due to these two No-GO conditions, a HOLD was called immediately before the countdown would have resumed. Since the launch had been re-targeted for the center of the night's launch window at 1:47:35 a.m. local time, the launch team only had half a minute before window time ran out – not nearly enough time to troubleshoot the suspect current signature and clear the range. With the launch officially scrubbed, teams headed into safing of the Delta II rocket and de-tanking procedures.

The initial call made to the launch team instructed a 24-hour recycle operation to go in motion with an identical launch window of 9:47:02 to 9:48:08 UTC on Wednesday, looking at 80% odds of favorable weather with ground winds remaining the primary concern for the nighttime liftoff.

This is the second launch from the U.S. to be impacted by range intrusions in the last week after the Antares rocket launching the Cygnus OA-8 cargo spacecraft (http://spaceflight101.com/cygnus-oa8/wp-admin/) had to abort its countdown on Saturday due to a low-flying aircraft moving into the closed airspace around the rocket's Wallops Island launch complex. Antares had to move to the back of its five-minute launch window on Sunday as boats had to be moved out of the off-shore hazard area.

For Delta II missions from the Western Range, closed air and marine space exists for the standard hazard zone around the launch pad to protect the public in the event of an explosion on the pad or failure early in flight. Additional offshore areas are closed for Delta II launches due to the six impacting Solid Rocket Motors that separate only 86 seconds into the flight and are actually held after burnout to ensure their safe off-shore impact.

One additional peculiarity for nine-booster Delta II vehicles is the ejection of three nozzle plugs from the three air-lit boosters which are the first components coming off the launch vehicle as the air-lits ignite around 65 seconds into the mission. These three plugs have been known to actually make their way back to shore if upper level wind conditions are just right, requiring careful planning of exclusion zones.

The Joint Polar Satellite System finds its roots in the National Polar-Orbiting Operational Environmental Satellite Program (NPOESS) that was initiated in 1994 when efforts began to consolidate the mostly separate weather satellite programs of NASA/NOAA and the U.S. Air Force. This three-agency effort eventually failed and the White House cut the cord in 2010 when the civilian and military programs were split up again with NASA/NOAA transitioning into the Joint Polar Satellite Program.

Current plans call for a pair of JPSS missions, JPSS-1 launching this week, and JPSS-2 in 2022 to sustain operations through 2028 when JPSS follow-on satellites or a new program of its own would begin operations. JPSS-1 is a close copy of the Suomi NPP satellite, built by Ball Aerospace, while JPSS-2 will be based on a platform provided by Orbital ATK. JPSS-1 is based on the BCP-2000 satellite platform and has a launch mass of 2,540 Kilograms, standing 4.2 meters tall and hosting over 450 Kilograms in payload mass for its five instruments. The satellite will communicate through a number of ground stations as well as the Tracking and Data Relay Satellite System to enable a fast data pipeline with a typical acquisition to product turnaround of under 85 minutes to allow operational application of data provided by the satellites in weather now- and forecasting.

ЦитироватьBoats in safety zone, technical problem combine to scrub Delta 2 launch

United Launch Alliance called off the launch of a Delta 2 rocket from California's Central Coast early Tuesday after boats venturing into a restricted safety exclusion zone and engineers ran out of time to resolve a technical problem on the launcher.

The Delta 2 rocket had only 66 seconds to take off Tuesday from Vandenberg Air Force Base in California, or else launch another day. Engineers sel ected short launch window to allow the mission's JPSS 1 weather satellite payload to enter an optimal orbit circling over Earth's poles.

Спойлер

Launch officials aborted the countdown as it was scheduled to resume after a pre-planned hold at T-minus 4 minutes.

"Hold hold hold," a member of the launch team called out over the countdown net.

ULA said in a statement that two issues prevented launch Tuesday. The Air Force's Western Range reported it was "red" due to boats that ventured into restricted waters in the Pacific Ocean too close to the Delta 2's flight path, and a technical problem on the Delta 2 triggered an alarm in the final minutes of the countdown.

"Due to the short window there was insufficient time to fully coordinate a resolution," ULA said in a statement.

Liftoff from Space Launch Complex 2-West at Vandenberg was rescheduled for Wednesday at 1:47:03 a.m. PST (4:47:03 a.m. EST; 0947:03 GMT), one second later than the opening of Tuesday's launch window. Like Tuesday's launch attempt, the Delta 2 will have 66 seconds to get off the ground.

"Up until the last 10 minutes, about the only thing we were working had to do with a couple of boats in the boat exclusion area off the coast here," said Omar Baez, NASA's launch manager for the mission. "Shortly (later), as we were trying to come out of that hold, one of the paramters on the first stage went out of limits, and there were some short brief discussions.

"With the short window, there wasn't enough time to outbrief that issue and come to resolution, and a hold was called just before we were supposed to go into the T-minus 4 (minute) count," he said. "So we're setting up for a 24-hour recycle."

Members of the launch team discussed an issue in the steering system of the Delta 2's main engine just prior to scrubbing the launch.

The JPSS 1 weather satellite mounted on top of the 128-foot-tall (39-meter) Delta 2 rocket is the first in a new line of polar-orbiting meteorological observatories for NOAA. Carrying five instruments, the satellite — set to be renamed NOAA 20 once in space — will fly more than 500 miles (800 kilometers) above Earth for a planned seven-year mission.

NASA acts as a procurement and technical agent for the development and launch of NOAA weather satellites.

The launch of JPSS 1 will be the penultimate flight of a Delta 2 rocket after more than 150 missions since its debut in 1989. One more Delta 2 launch is planned fr om California in late 2018 with NASA's ICESat 2 mission.

NOAA's JPSS 1 weather satellite is enshrouded inside the nose fairing of a Delta 2 rocket, awaiting liftoff fr om Vandenberg Air Force Base in California on a seven-year mission to collect data to improve global weather forecasts.

Спойлер

The satellite weighs around 5,025 pounds (2,280 kilograms), according to NOAA, and will orbit more than 500 miles (800 kilometers) above Earth with a suite of sensors and instruments measuring conditions in the atmosphere, monitoring the health of the ozone layer, and detecting how much thermal radiation is reflected off the planet.

The measurements are vital to feed data into numerical forecast models used to generate medium-term weather outlooks extending out to seven days.

The spacecraft was built by Ball Aerospace and Technologies Corp. in Boulder, Colorado, and is based on the contractor's Ball Configurable Platform (BCP) 2000 satellite design.

JPSS 1's solar panels are folded up for launch to fit inside the Delta 2 rocket's 10-foot-diameter (3-meter) payload shroud. These photos show the two halves of the Delta 2's fairing enclosure inside the mobile service tower at Space Launch Complex 2-West, wh ere technicians prepared to encapsulate the JPSS 1 satellite on top of the rocket.

The current weather conditions at Space Launch Complex 2-West are observed "green," and are forecast to remain acceptable for launch throughout the countdown. There is a 0 percent chance of violating the Delta 2's launch weather constraints.

The outlook for launch time calls for high clouds at 24,000 feet, unrestricted visibility, winds from the east at 6 to 9 knots, and a temperature in the upper 40s to lower 50s Fahrenheit.

The liquid oxygen tank on the Delta 2 rocket's first stage is now full. Liquid oxygen will continue flowing into the tank throughout the countdown to replace the super-cold oxidizer as it naturally boils away. The liquid oxygen loading operation in today's countdown took 25 minutes, 18 seconds.

With the completion of liquid oxygen tanking, the Delta 2 rocket now stands fully fueled for launch with the JPSS 1 weather satellite at 1:47:35 a.m. PST (4:47:36 a.m. EST; 0947:36 GMT) from Vandenberg Air Force Base, California. RP-1 fuel was loaded into the first stage earlier in the countdown, and the second stage received its blend of Aerozine 50 and nitrogen tetroxide hypergolic propellants earlier in the launch campaign. The nine solid rocket boosters came with their propellants pre-packed.

Today's second launch attempt of NOAA's Joint Polar Satellite System-1, or JPSS-1, on a United Launch Alliance Delta II rocket from Vandenberg Air Force Base in California has been scrubbed. Launch team managers made the decision due to upper level wind conditions that would not be cleared at the time of launch.

The penultimate Delta II rocket encountered a second launch scrub on Wednesday, keeping the first satellite in the Joint Polar Satellite System grounded for at least another day, possibly more given an unfavorable outlook for conditions in the upper atmosphere over the California launch site.

Спойлер

Delta 378 had to abandon its first launch attempt in the early hours on Tuesday due to an out-of-spec indication on an engine actuator and a fouled range by boats entering the offshore hazard area. The 39-meter tall rocket spent Tuesday protected inside its Mobile Service Tower while engineers reviewed the technical issue before clearing the vehicle for another try Wednesday morning. Clocks started ticking back from T-2 hours and 30 minutes after an hour-long hold, picking up with activation of the rocket's flight control system for checkouts followed by loading the first stage with 96 metric tons of Rocket Propellant 1 and Liquid Oxygen.

Delta II stood fully fueled and checked off final engine steering checks as countdown operations proceeded without any technical issues. Range Weather was given as 100% favorable for launch, but balloons measuring conditions in the upper atmosphere showed brisk winds from the west, violating Delta II's launch criteria.

Upper Level Winds are not part of the range weather criteria and the percentage of cooperative weather issued prior to launch. Instead, winds aloft are examined under vehicle-specific flight dynamics analysis to ensure forces encountered by the ascending launch vehicle do not exceed its structural limits.

In the L-30-minute weather briefing, the Launch Weather Officer reported data from the last pre-launch weather balloon, showing upper level winds from the west at 250° at a present speed of 114 knots with further strengthening to 120 kts expected until liftoff. With this unfavorable outlook, the Delta II launch team around Launch Director Tom Heter and Launch Conductor Scott Barney was forced to back out of the countdown at T-6 minutes and 42 seconds, pressing into de-tanking.

Per the standard operational procedure, the Delta II launch team went into a 24-hour turnaround to preserve the opportunity of launching Thursday morning, though meetings later in the day will determine whether an attempt will be made based on upper level wind forecasts. Although Range Weather is expected to remain favorable through Thursday's backup slot, there is not much hope for improvement higher up in the atmosphere.

Flow from the west will prevail over the next 24 hours with upper level winds of 125 knots predicted for Thursday's opportunity, slightly stronger than Wednesday from the same direction. The wind direction will shift slightly west to 260° by Friday morning, remaining strong at 120 knots as the result of a frontal system approaching the launch base.

NASA said in a statement after Wednesday's Scrub that assessments on when the next launch attempt can made are underway, also in coordination with the Western Range. The earliest possible launch window available for the mission opens at 9:47 UTC on Thursday.

NOAA's Joint Polar Satellite System-1 spacecraft will launch aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2 at California's Vandenberg Air Force Base. Launch managers are working to determine a launch date after today's planned liftoff was scrubbed due to upper-level winds.

The ULA launch team is expected to reschedule the next Delta 2 launch attempt for Saturday, with a backup day of Sunday, pending final approval of the U.S. Air Force's Western Range at Vandenberg Air Force Base.

High-altitude winds over the next couple of days are forecast to be much like conditions today, so officials want to wait for improved winds before making another launch attempt.

The launch time Saturday will be 1:47 a.m. PST (4:47 a.m. EST; 0947 GMT).

The Delta 2 rocket and the JPSS 1 weather satellite on-board have been safed, and the booster's first stage has been drained of propellant following the scrub earlier this morning.

Brisk upper level winds blowing from the west thwarted a second try to launch a new NOAA weather satellite aboard a United Launch Alliance Delta 2 rocket Wednesday, likely postponing the liftoff from Vandenberg Air Force Base in California until at least Saturday.

High-altitude were measured at more than 110 knots (126 mph) by a weather balloon sent aloft from Vandenberg during Wednesday's early morning countdown. Safety officials from the U.S. Air Force's Western Range were concerned the winds might blow debris from the rocket, such as nozzle covers on the Delta 2's air-lit solid rocket boosters, back over populated areas on land as it climbs south over the Pacific Ocean.

Спойлер

Six of the Delta 2's nine strap-on solid-fueled motors will ignite on the launch pad to boost the 128-foot-tall (39-meter) rocket skyward, along with the first stage's liquid-fueled RS-27A main engine. Once the six ground-lit boosters burn out, three air-lit boosters will fire about a minute into the flight, ejecting plugs from their nozzles when they ignite.

Similar strong upper level winds are predicted Thursday and Friday. ULA is expected to target the Delta 2's next launch attempt Saturday at 1:47 a.m. PST (4:47 a.m. EST; 0947 GMT).

The scrubbed launch attempt Wednesday came 24 hours after ULA aborted a countdown when boats ventured into an offshore safety exclusion zone near the Delta 2's flight path, and a technical problem cropped up a few minutes before liftoff.

The launch of the JPSS 1 weather satellite will mark the 154th flight of a Delta 2 rocket since 1989, and the 378th mission by the Delta family of launch vehicles since 1960. One more Delta 2 mission is on the books for late 2018 with NASA's ICESat 2 mission to measure the shrinkage of Earth's ice caps.

Built by Ball Aerospace and Technologies Corp., the 5,025-pound (2,280-kilogram) JPSS 1 satellite is the first of new NOAA polar-orbiting weather observatories. The Joint Polar Satellite System, succeeding from a precursor series of weather satellites, will ensure data on atmospheric chemistry, clouds, fog, smoke, temperature, humidity, and Earth's ozone layer reach scientists and weather forecasters through at least 2038.

The Delta 2 launch crew at Vandenberg Air Force Base in California is prepping for another launch attempt early Saturday with NOAA's JPSS 1 polar-orbiting weather satellite.

The 66-second launch window opens at 1:47:03 a.m. PST (4:47:03 a.m. EST; 0947:03 GMT), but officials are expected to target liftoff in the middle of the window.

Спойлер

This afternoon at Space Launch Complex 2-West, technicians will wheel away the mobile gantry from the Delta 2 rocket, revealing the launcher on its mount overlooking the Pacific Ocean.

The three-hour countdown will commence at 10:47 p.m. PST (1:47 a.m. EST; 0647 GMT), and the launch team will load refined RP-1 kerosene and liquid oxygen into the Delta 2's first stage. The rocket's second stage consumes pre-loaded storable liquid propellants, and the nine strap-on boosters are solid-fueled.

The weather outlook calls for a 100 percent chance of acceptable conditions at the launch pad during Saturday's brief launch window.

A front passed through the area Friday, and forecasters predict drying and cooler conditions during the countdown.

Conditions at launch time should be favorable, with northerly winds of 15 to 20 knots and temperatures in the upper 40s to lower 50s Fahrenheit.

Winds aloft are not expected to be as strong Saturday morning as they were Wednesday, when the upper level winds exceeded range safety constraints.

The strongest high-altitude winds should be around 85 knots between 40,000 and 45,000 feet, but the final say on the acceptability of the winds aloft will come from data collected by weather balloons launched in the final hours of the countdown.

The liquid oxygen tank on the Delta 2 rocket's first stage is now full. Liquid oxygen will continue flowing into the tank throughout the countdown to replace the super-cold oxidizer as it naturally boils away. The liquid oxygen loading operation in today's countdown took 25 minutes, 17 seconds.

With the completion of liquid oxygen tanking, the Delta 2 rocket now stands fully fueled for launch with the JPSS 1 weather satellite at 1:47 a.m. PST (4:47 a.m. EST; 0947 GMT) from Vandenberg Air Force Base, California. RP-1 fuel was loaded into the first stage earlier in the countdown, and the second stage received its blend of Aerozine 50 and nitrogen tetroxide hypergolic propellants earlier in the launch campaign. The nine solid rocket boosters came with their propellants pre-packed.

The launch team is beginning the "slew" or steering checks of the first and second stage engines. These are gimbal tests of the nozzles on the first stage main engine and twin vernier engines and second stage engine to ensure the rocket will be able to steer itself during launch.

Testing of the Delta 2's flight termination system, which would be used to end the flight in the event of a mishap, was also accomplished in the last few minutes.

ЦитироватьSecond-To-Last Delta II Successfully Delivers JPSS-1 Weather Satellite to Orbit
November 18, 2017 (http://spaceflight101.com/jpss-1/delta-ii-launches-jpss-1-weather-satellite/)

The second-to-last Delta II rocket lit up the night over California's Vandenberg Air Force Base in the early hours on Saturday, taking to the skies with the JPSS-1 Weather Satellite for NASA and NOAA, set to become America's primary meteorological spacecraft in Polar Orbit. Checking off its 99th consecutive success and 154th overall mission, Delta II successfully placed the 2,540-Kilogram satellite into orbit 57 minutes and 30 seconds after its nighttime blastoff.

Delta II, counted on for many years by numerous missions to Earth orbit and beyond, is approaching its final flight assignment in 2018 with NASA's ICESat-II that will close out a career of nearly three decades for the former workhorse of the American space program. Debuting in 1989, Delta II became the most-flown U.S. launch vehicle, lifting government and commercial satellites into Earth orbit and deploying flagship missions for NASA including the Mars Exploration Rovers and the Kepler Exoplanet telescope.

The venerable Delta II kept up a remarkable record of 151 successful missions out of 153 launches, encountering one partial failure and one outright failure when a crack in one of the rocket's boosters caused a spectacular explosion of Delta 241 in 1997 during the rocket's initial climb-out fr om Cape Canaveral. Saturday's launch was the 53rd Delta II launch for NASA and the 723rd of a Thor-based launch vehicle finding its roots in the very beginnings of America's space program.

Delta II completed its final launch from Cape Canaveral in 2011 on the GRAIL mission to explore the Moon's gravity and its final launches are dedicated to Earth science, requiring only the Vandenberg launch complex at SLC-2W to be kept in operation until the vehicle's retirement.

Saturday's mission marked the final flight of the nine-booster Delta II variant known as 7920, hosting the Thor-XLT as first stage and a hypergolic-fueled Delta-K second stage with nine GEM-40s clustered around the core. Standing 39 meters tall with a core diameter of 2.34 meters and a launch mass of 228 metric tons, Delta II can lift up to three metric tons into a Sun Synchronous Orbit.

Hidden under Delta II's three-meter payload fairing was the first satellite of the Joint Polar Satellite System, becoming America's primary weather asset in polar orbit. Operational meteorological satellite architectures typically employ satellites in Geostationary Orbits to capture high-revisit data to monitor weather systems while polar-orbiting satellites provide detailed atmospheric properties to be combined for weather forecast models.

The Joint Polar Satellite System (JPSS) was born out of the National Polar-Orbiting Operational Environmental Satellite System (NPOESS) initiated in the 1990s in an effort to consolidate the civilian weather program operated by NOAA/NASA and the military's Defense Meteorological Satellite Program. However, the tri-agency effort ended in a fiasco with budget overruns by a factor of two and years of delays as collaboration between three government agencies with different objectives and long-standing acquisition techniques proved impossible.

The programs were again split up in 2010 with NOAA and NASA proceeding into the JPSS Program to provide continuation for weather data collection in an afternoon orbit while the morning orbit will be covered through international cooperation with Europe's MetOp program.

Suomi NPP, originally intended as a pathfinder for the NPOESS program, launched in 2011 as a demonstration mission and as gapfiller to continue NOAA's operational record begun in the 1970s with the most recent satellite, NOAA-19, launching in 2009.

Standing 4.2 meters tall, the JPSS-1 satellite was built by Ball Aerospace as a close copy of the Suomi NPP spacecraft with strategic improvements on the craft's thrusters, internal data transmission system and communications system that now includes the ability of sending data back through NASA's Tracking and Data Relay Satellite System in addition to a series of ground stations.

JPSS-1 employs Ball's BCP-2000 satellite platform and hosts five instruments developed by a number of contractors, covering typical meteorological sensors like visible and infrared imaging equipment, a microwave sounder to extract atmospheric profiles and an infrared spectrometer for refinement of profiling data and atmospheric constituent data. Additionally, JPSS hosts specialized instruments to measure ozone, of interest in operational UV index forecasting and of great importance to the scientific community looking at ozone hole recovery, and JPSS hosts a dedicated instrument measuring Earth's Energy Budget – identified as one of the most critical climate variables.

The primary imaging instrument of JPSS-1 is the Visible Infrared Radiometer Suite (VIIRS), a scanning instrument covering a broad ground swath of 3,040 Kilometers in 22 spectral channels to create color imagery to monitor cloud patterns, infrared data is applied to surface and ocean temperature measurements and cloud property assessments, and a special day-and-night band delivers cloud imaging in virtually all lighting conditions. The primary atmospheric profilers on JPSS are the Advanced Technology Microwave Sounder (ATMS) – a 22-channel microwave radiometer – and the Cross-Track Infrared Sounder – a 1,305-channel Fourier-transform infrared spectrometer, delivering temperature and humidity profiles from ground level into the upper troposphere to provide information on atmospheric disturbances and constituent concentration.

JPSS-1 is the first of four planned JPSS spacecraft to guarantee access to weather data through the 2020s and into the first half of the 2030s with each satellite expected to operate for seven years and sufficient overlap between missions for cross calibration. To be re-named NOAA-20 once in operation, JPSS-1 will be placed opposite Suomi NPP to optimize the two-satellite system for revisit rate to get the most out of NPP's remaining years of operation.

Delta II had to remain on the ground after launch scrubs on Tuesday and Wednesday, the first due to a technical issue and fouled range followed by a 24-hour turnaround that eventually ended when upper level winds intensified beyond allowable limits for the Delta II rocket. Teams had to stand down Thursday and Friday as winds aloft were forecast to remain strong.

Countdown operations again went in motion Friday afternoon with the retraction of the Mobile Service Tower, enabling teams to close out the launch pad by removing access platforms around the base of the rocket before evacuating the complex, at which point the RIFCA, Delta's primary flight control assembly was powered up for checkouts and reconfigurations.

Over the course of a 20-minute sequence, Delta II's first stage received nearly thirty metric tons of Rocket Propellant 1, followed by loading 67 metric tons of -183°C Liquid Oxygen inside L-2 hours. Standing fully fueled, Delta II went through pressurization checks and gimbal checks on all engines confirmed the vehicle would have good thrust vector control on its way into orbit.

Weather was no issue through the night and all operations proceeded smoothly as Delta received its upd ated flight software and JPSS-1 switched to internal power for its climb to orbit. T-0 was re-aligned for the middle of the day's brief 66-second launch window to position the satellite in the optimal slot relative to Suomi NPP. A unanimous GO for launch was given by all Stations when polled during the T-4-minute hold, allowing the countdown to proceed into its automated sequence.

Delta II was commanded to switch to battery power and all onboard ordnances were armed before final pressurization started at T-3 minutes on the first stage fuel tank and T-2 minutes for Liquid Oxygen. Final verifications of hydraulic pressures occurred at T-90 seconds and the Western Range reported clearance for launch before Delta's flight computer assumed control at T-1 minute, heading towards the hands-off point for launch controllers at T-10 seconds.

Delta 378 came to life at T-3 seconds when the RS-27A main engine was fired up to soar to a launch thrust of 91 metric-ton-force along with its two LR-101 sustainer engines to assist in attitude control and add another metric ton of thrust. Clocks hit zero at 9:47:36 UTC and Delta II lit six of its nine Solid Rocket Motors to leap off the pad with a peak thrust of 480 metric-ton-force.

Lighting up the night over Vandenberg, Delta II did not hang around and was off in a hurry – climbing vertically for less than ten seconds before initiating its pitch maneuver to depart to the south-west heading for a 98.7-degree orbit. The vehicle passed the speed of sound 33 seconds after launch and pressures on the boosters began to plateau as the vehicle made its way through Maximum Dynamic Pressure 47 seconds into flight.

The six ground-lit boosters exhausted their 11,800-Kilogram propellant load after 63 seconds of firing time and burnout of the ground-lits prompted Delta II to fire up the remaining three GEM-40s, continuing toward orbit with a thrust of 304 metric-ton-force. Delta II held the spent ground lit boosters until T+1 minute and 26 seconds when the 11-meter long SRMs were jettisoned in two groups, ensuring a safe off-shore impact.

The three air-lits dropped away from the ascending rocket two minutes and 11 seconds after launch at which point Delta II weighed less than half of what it did at liftoff. With all boosters cleanly separating, Delta II continued blazing towards orbit relying on its first stage alone, creating a vacuum thrust of 107,500 Kilogram-force as it burned 365 Kilograms of propellant per second.

]MECO – Main Engine Cutoff was called out four minutes and 23 seconds into the flight when the first stage shut down the RS-27A engine with the twin sustainer engines continuing to burn another four seconds for an attitude stabilization before shutting down as well. The 26-meter long first stage departed the stack four minutes and 31 seconds after launch, handing off to the Delta-K for the final boost to orbit.

Six seconds after staging, Delta-K fired up its 4,350-Kilogram-force AJ-10-118K engine burning a self-igniting mixture of six metric tons of Aerozine-50 fuel and Nitrogen Tetroxide oxidizer. Just five seconds into operation of the second stage, Delta II split open and jettisoned its two 8.5-meter long fairing halves after crossing 150 Kilometers in altitude wh ere aerodynamic forces were no-longer a threat to the satellite.

The initial boost by the Delta-K was by far the longest of its four burns on Saturday, firing for just over six minutes to inject the stack into an elliptical Parking Orbit. Shutdown was confirmed ten and a half minutes after liftoff and Delta's onboard navigation system showed an orbit of 185 by 865 Kilometers as the vehicle headed into a coast phase of 40 minutes to climb to the peak of the preliminary orbit.

AJ-10 re-started 50 minutes and 50 seconds after launch and fired for just 24 seconds to circularize the orbit at 830 Kilometers in altitude with measured orbital parameters lining up very well as Delta's navigation system showed injection at 816 by 828 Kilometers, 98.72°. Arriving in its target orbit, Delta-K used its thrusters to re-orient for the separation of the JPSS-1 satellite 57 minutes and 30 seconds after blastoff, sailing off on a mission of at least seven years to continue the collection of world-class weather forecasting data and climate parameters.

Separation of the primary payload did not mark the end for the Delta-K stage that had five CubeSats riding shotgun with JPSS-1, separating after a 10.2-second orbit-lowering maneuver performed right at the T+75-minute mark to adjust the orbit to 450 x 812 Kilometers, 97.7°. Packed in three deployers were two three-unit and three one-unit CubeSats four of which were flying under NASA's Educational Launch of Nanosatellites (ELaNa) program.

MiRaTa (http://spaceflight101.com/jpss-1/mirata/), the Microwave Radiometer Technology Acceleration Satellite, is a technology demonstration of NASA and MIT, using a miniaturized microwave radiometer and GPS occultation instrument to demonstrate a potentially ground-breaking onboard calibration technique for future weather satellites. The Buccaneer Risk Reduction Mission (http://spaceflight101.com/jpss-1/buccaneer-rrm/) is being flown in a joint initiative of the University of New South Wales and the Australian Defence Ministry, geared toward demonstrating the deployment of a spaceborne high-frequency antenna in preparation for the operational Buccaneer mission that will be used to calibrate the Jindalee over-the-horizon radar.

The three 1U CubeSats (http://spaceflight101.com/jpss-1/jpss-1-secondary-payloads/) flying on Delta II are RadFxSat from Vanderbilt University looking into radiation effects on electronics, Embry-Riddle's Eagle Sat that also studies the effect of radiation on memory in space, and MakerSat 0 – demonstrating a different paradigm of CubeSat assembly and launch that would allow for several science payloads to be integrated into a modular 1U platform on demand, including space-based assembly on the International Space Station before deployment.

After sending the CubeSats on their way, the Delta-K stage was se t for a 41-second deorbit burn one hour and 51 minutes into the flight to place it on a sub-orbital arc for destructive re-entry and splashdown of surviving components two hours and 11 minutes after liftoff.

"It has been an honor to partner with our teammates at NASA and NOAA in launching this critical earth observation mission," said Laura Maginnis, ULA vice president of Government Satellite Launch. "Together, we were able to overcome multiple challenges in the last two weeks, culminating in the successful delivery of JPSS to orbit today."

In addition to JPSS-1, this mission includes five CubeSats which launched from dispensers mounted to the Delta II second stage. The miniaturized satellites will conduct research in 3D-printed polymers for in-space manufacturing, weather data collection, bit flip memory testing, radar calibration and the effects of space radiation on electronic components.

This mission was launched aboard a Delta II 7920-10 configuration rocket which includes a 10-ft diameter Payload Fairing (PLF). The booster for this mission was powered by the RS-27A engine and the second stage was powered by the AJ10-118K engine. This is ULA's 8th launch in 2017 and the 123rd successful launch since the company was formed in December 2006. This is the penultimate launch of the Delta II rocket, first launching in 1989 with 154 launches to date. The final Delta II mission is scheduled for 2018 and will put ICEsat-2 in orbit for NASA.

"The Delta II rocket has truly created a legacy throughout its history, and has proven to be an industry workhorse," said Maginnis. "After almost 3 years since our last Delta II mission, it was great to see it flying and delivering mission success for our customers once again."

ULA's next launch is the NROL-47 for the National Reconnaissance Office. The launch is scheduled for Dec. 13 from Space Launch Complex-6 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 120 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.

BOULDER, Colo., Nov. 18, 2017 — NOAA's Joint Polar Satellite System-1 (JPSS-1) successfully launched this morning at 1:47 a.m., PST, from Vandenberg Air Force Base, California, aboard a United Launch Alliance Delta II rocket. Ten minutes after launch vehicle separation, the spacecraft successfully deployed its solar array which provides its electrical power, and established communications with mission operators.

Спойлер

"JPSS-1 is one of the most advanced environmental systems ever created by government and industry partners – NOAA, NASA, Ball, Harris, Raytheon, Northrop Grumman and United Launch Alliance," said Rob Strain, president, Ball Aerospace. "The information collected from its next-generation suite of instruments will soon deliver advanced data to help protect lives, property and our planet."

JPSS-1, or NOAA-20 as it will be known once it reaches its polar orbit, will join the Ball-built, Suomi National Polar-orbiting Partnership (http://www.ball.com/aerospace/programs/suomi-npp) (Suomi NPP), which has served as NOAA's primary operational satellite for global weather observations since May 2014. Together, the two satellites, each circling the Earth 14 times per day, will provide global observations for U.S. weather and environmental predictions.

The JPSS series of polar-orbiting weather satellites will work as the foundation of NOAA's operational environmental forecasting system for the next 20 years. The JPSS missions are funded by NOAA to provide global environmental data in low-Earth polar orbit. NASA is the acquisition agent for the flight systems, launch services and components of the ground segment.

Ball designed and built the JPSS-1 spacecraft, the Ozone Mapping and Profiler Suite (http://www.ball.com/aerospace/programs/omps)-Nadir instrument (OMPS-N), integrated all five of the satellite's instruments, performed satellite-level testing and launch support, and will hand over control of the satellite to NOAA 90 days after launch for continued operations. Ball will build the OMPS instruments for NOAA's Follow-On/JPSS-3 and JPSS-4 missions, under a sole source contract modification award from NASA.

NASA Launches NOAA Weather Satellite Aboard United Launch Alliance Rocket to Improve Forecasts

(https://img.novosti-kosmonavtiki.ru/207816.jpg) (https://www.nasa.gov/sites/default/files/thumbnails/image/jpss-launch-3a.jpg)
At Vandenberg Air Force Base's Space Launch Complex 2, the Delta II rocket engines roar to life. The 1:47 a.m. PST (4:47 a.m. EST), liftoff begins the Joint Polar Satellite System-1, or JPSS-1, mission. JPSS is the first in a series four next-generation environmental satellites in a collaborative program between NOAA and NASA.

NASA has successfully launched for the National Oceanic and Atmospheric Administration (NOAA) the first in a series of four highly advanced polar-orbiting satellites, equipped with next-generation technology and designed to improve the accuracy of U.S. weather forecasts out to seven days.

The Joint Polar Satellite System-1 (JPSS-1) lifted off on a United Launch Alliance Delta II rocket from Vandenberg Air Force Base, California, at 1:47 a.m. PST Saturday.

Approximately 63 minutes after launch the solar arrays on JPSS-1 deployed and the spacecraft was operating on its own power. JPSS-1 will be renamed NOAA-20 when it reaches its final orbit. Following a three-month checkout and validation of its five advanced instruments, the satellite will become operational.

Спойлер

"Launching JPSS-1 underscores NOAA's commitment to putting the best possible satellites into orbit, giving our forecasters -- and the public -- greater confidence in weather forecasts up to seven days in advance, including the potential for severe, or impactful weather," said Stephen Volz, director of NOAA's Satellite and Information Service.

JPSS-1 will join the joint NOAA/NASA Suomi National Polar-orbiting Partnership satellite in the same orbit and provide meteorologists with observations of atmospheric temperature and moisture, clouds, sea-surface temperature, ocean color, sea ice cover, volcanic ash, and fire detection. The data will improve weather forecasting, such as predicting a hurricane's track, and will help agencies involved with post-storm recovery by visualizing storm damage and the geographic extent of power outages.

"Emergency managers increasingly rely on our forecasts to make critical decisions and take appropriate action before a storm hits," said Louis W. Uccellini, director of NOAA's National Weather Service. "Polar satellite observations not only help us monitor and collect information about current weather systems, but they provide data to feed into our weather forecast models."

JPSS-1 has five instruments, each of which is significantly upgraded from the instruments on NOAA's previous polar-orbiting satellites. The more-detailed observations from JPSS will allow forecasters to make more accurate predictions. JPSS-1 data will also improve recognition of climate patterns that influence the weather, such as El Nino and La Nina.

The JPSS program is a partnership between NOAA and NASA through which they will oversee the development, launch, testing and operation all the satellites in the series. NOAA funds and manages the program, operations and data products. NASA develops and builds the instruments, spacecraft and ground system and launches the satellites for NOAA. JPSS-1 launch management was provided by NASA's Launch Services Program based at the agency's Kennedy Space Center in Florida.

"Today's launch is the latest example of the strong relationship between NASA and NOAA, contributing to the advancement of scientific discovery and the improvement of the U.S. weather forecasting capability by leveraging the unique vantage point of space to benefit and protect humankind," said Sandra Smalley, director of NASA's Joint Agency Satellite Division.

Ball Aerospace designed and built the JPSS-1 satellite bus and Ozone Mapping and Profiler Suite instrument, integrated all five of the spacecraft's instruments and performed satellite-level testing and launch support. Raytheon Corporation built the Visible Infrared Imaging Radiometer Suite and the Common Ground System. Harris Corporation built the Cross-track Infrared Sounder. Northrop Grumman Aerospace Systems built the Advanced Technology Microwave Sounder and the Clouds and the Earth's Radiant Energy System instrument.

ЦитироватьDelta II launch successful
30th Space Wing Public Affairs / Published November 18, 2017

VANDENBERG AIR FORCE BASE, Calif. --
A United Launch Alliance Delta II rocket carrying a NASA/National Oceanic and Atmospheric Administration satellite was successfully launched from Space Launch Complex-2 here Saturday, Nov. 18, at 1:47 a.m. PST.

The Delta II rocket carried the first satellite of the Joint Polar Satellite System.

Col. Greg Wood, 30th Space Wing vice commander, was the space launch commander.

The Joint Polar Satellite System (JPSS) is the Nation's advanced series of polar-orbiting environmental satellites. JPSS represents significant technological and scientific advancements in observations used for severe weather prediction and environmental monitoring. This data is critical to the timeliness and accuracy of forecasts three to seven days in advance of a severe weather event. JPSS is a collaborative effort between NOAA and NASA.

A United Launch Alliance Delta 2 rocket climbed into space Saturday from California with a $1.6 billion polar-orbiting weather satellite for NOAA, the first of four upgraded observatories designed to keep vital meteorological data flowing to forecasters for the next two decades.

The government-owned weather sentinel was deployed into orbit more than 500 miles (800 kilometers) above Earth by the Delta 2 rocket to begin a seven-year mission.

The successful launch was the second-to-last flight of a Delta 2 rocket, but it also signaled a beginning for NOAA's Joint Polar Satellite System, a multi-spacecraft program established in 2010 under civilian leadership after the cancellation of an over-budget joint weather satellite initiative with the U.S. Air Force.

Atmospheric measurements from the new satellite will feed computations by numerical prediction models, which process data multiple times every day to forecast storm developments and movements days and weeks ahead of time.

But the finely-tuned computer models are worthless without accurate data inputs, and NOAA's polar-orbiting weather satellites gather much of information fed into models that predict hurricane tracks, flooding rains and winter storms before they arrive.

JPSS 1 will be renamed NOAA 20 once it reaches its final orbit and becomes operational in approximately 90 days.

"Launching JPSS 1 underscores NOAA's commitment to putting the best possible satellites into orbit, giving our forecasters — and the public — greater confidence in weather forecasts up to seven days in advance, including the potential for severe, or impactful weather," said Stephen Volz, director of NOAA's satellite and information service.

The Delta 2 rocket fired its RS-27A main engine in the final few seconds of Saturday's countdown, and six strap-on solid rocket boosters ignited at 1:47:36 a.m. PST (4:47:36 a.m. EST; 0947:36 GMT) to propel the launcher away from Space Launch Complex 2-West at Vandenberg Air Force Base northwest of Los Angeles.

The main engine and six boosters combined to generate nearly 800,000 pounds of thrust at full power, sending the half-million-pound Delta 2 rocket faster than the speed of sound in 33 seconds as it quickly arced south from Vandenberg.

The six ground-lit boosters, made by Orbital ATK, burned out after about one minute, and three air-lit motors ignited to continue the trip into space. The first six boosters jettisoned to fall into the Pacific once the Delta 2 was safely away from offshore oil rigs, and the other three followed less than a minute later.

The Aerojet Rocketdyne RS-27A main engine, with design roots from the Saturn 1 and 1B rockets of the 1960s, continued firing with 200,000 pounds of thrust, consuming a mixture of rocket-grade RP-1 kerosene and liquid oxygen.

The Delta 2's first stage shut down and jettisoned around four-and-a-half minutes into the flight, leaving the second stage's AJ10-118K engine to complete multiple firings to place the JPSS 1 weather satellite and five secondary CubeSat payloads in orbit.

The second stage engine's first burn ended nearly 11 minutes after liftoff, and the rocket passed over Antarctica before heading northbound over the Indian Ocean. Then its engine fired again for a 24-second engine restart.

The second AJ10 engine firing placed the JPSS 1 spacecraft in its planned 500-mile-high nearly-circular orbit orbit, setting the stage for deployment of the satellite at T+plus 57 minutes, 30 seconds.

Live video transmitted from the rocket showed the JPSS 1 satellite receding from the second stage after explosive bolts and springs engaged to push the craft away.

Engineers with Ball Aerospace and Technologies Corp., JPSS 1's manufacturer in Boulder, Colorado, confirmed the satellite unfurled its power-producing solar array wing as scheduled a few minutes later. The solar panel extension is one of the first major steps in the life of a satellite.

Meanwhile, the Delta 2's second stage maneuvered away from JPSS 1 and ignited its engine a third time to slightly shift its orbit for release of five CubeSats developed for educational and research missions and sponsored by NASA.

The CubeSats range in scale from the size of a Rubik's Cube to a toaster oven, and NASA paid for their launch on the Delta 2 rocket.

The five CubeSats launched Saturday included payloads developed by students and research institutions, along with an experimental nanosatellite from the Australian military. A summary of the CubeSat missions was released by NASA:

[/li]
• MiRaTA, a compact atmospheric sensing nanosatellite from Massachusetts Institute of Technology that will measure temperature, water vapor, and cloud ice in the atmosphere for severe weather monitoring and the study of cyclone structure.
• MakerSat-0, a CubeSat from Northwest Nazarene University in Nampa, Idaho, carrying several student-build experimental payloads.
• RadFxSat, a technology demonstration mission to monitor ionizing radiation effects in a memory integrated circuit from Vanderbilt University and AMSAT.
• EagleSat-1, a scientific investigation developed by Embry-Riddle Aeronautical University in Prescott, Arizona, that will attempt to measure the decay of the satellite's orbit over time by the means of an unlocked Global Positioning System receiver in the space environment.
• Buccaneer, a CubeSat developed by the Australian Department of Defence and the University of New South Wales that carries a 10.5-foot (3.2-meter) deployable antenna to calibrate over-the-horizon radars used by the Australian military.
  

The CubeSats were ejected from three PPOD carriers affixed to the Delta 2's second stage, and telemetry radioed from the rocket indicated all three deployers opened their doors as expected.

A final burn of the second stage engine steered the rocket on a trajectory toward a destructive re-entry to keep it from becoming another piece of space junk.

"Things went absolutely perfect today," said Omar Baez, the NASA launch manager for Saturday's flight. "The weather cooperated with us, and the upper level winds cooperated with us. The vehicle was perfect, the spacecraft was perfect. The range instrumentation worked great. Couldn't ask for better.

"The nation's got another wonderful weather asset up in space, and we can't wait to have the products coming back from it," Baez said.

Two launch attempts earlier in the week were scrubbed by boats that ventured into an offshore exclusion zone, a technical alarm on the rocket, and brisk westerly winds aloft that threatened to blow debris from the Delta 2 back over land.

"It took a little bit longer than we thought, but we got it done," Baez said.

JPSS 1 is the first of four new polar-orbiting satellites under development by NOAA in partnership with NASA. The quartet will ensure the U.S. weather agency continues receiving measurements from polar orbit through 2038, officials said.

The $1.6 billion satellite mission features five instruments to monitor Earth's atmosphere, ozone layer and radiation reflectance, providing data for numerical forecast models designed to produce three-to-seven day weather outlooks.

The JPSS program overall is budgeted at $11.3 billion, including the satellites, instruments, launch services and ground network.

"These are exciting times for NOAA," said Ajay Mehta, acting director for systems in NOAA's satellite and information service.

The first in a new generation of geostationary satellites, named GOES-R before launch and since renamed GOES-16, lifted off from Cape Canaveral last November.

The geostationary satellites provide near real-time imagery of cyclones, storms, lightning and other phenomena, while polar-orbiting weather satellites gather background data on the forces that drive changing weather patterns.

"The satellite systems are complementary, and both are critical for NOAA to provide a complete picture of what's happening with the weather today, tomorrow, next week, or next month," Mehta said before JPSS 1's launch.

JPSS 1 follows the launch of a pathfinder satellite named Suomi NPP in October 2011. That spacecraft is now operating beyond its design life, and JPSS 1's launch was timed — to the second — to allow it to enter an orbit around 50 minutes behind Suomi-NPP for tandem observations.

Suomi NPP was built as a demonstration for the new-generation NOAA weather satellites, but forecasters now rely on its measurements to fill a gap between the last of the previous line of polar-orbiting platforms, which launched in 2009, and JPSS 1.

While JPSS 1 is the first in a new generation of weather satellites, its launch extends a line of meteorological spacecraft dating back to 1960.

"To provide the observations, JPSS carries five highly sophisticated instruments, instruments so precise that they can measure temperatures to better than one-tenth of a degree in the entire atmosphere from the Earth's surface up to the edge of space," said Greg Mandt, director of the JPSS program at NOAA.

The second JPSS mission is scheduled to launch in 2021 on a ULA Atlas 5 rocket from Vandenberg.

NOAA, the U.S. Air Force and Eumetsat, the European weather satellite agency, have a partnership to share data collected by each organization's polar-orbiting meteorological observatories. NOAA's satellites have afternoon coverage, and the U.S. military's DMSP satellites fly in a similar polar orbit with early morning passes. Europe's Metop spacecraft are in orbits timed to make observations in mid-morning.

Saturday's launch marked second-to-last flight of the venerable Delta 2 rocket, which has conducted 154 missions since its introduction in 1989, launching interplanetary missions to the moon, Mercury, Mars, comets and asteroids, NASA's planet-hunting Kepler observatory, and numerous commercial and military satellites, including the bulk of the GPS navigation network in the 1990s and 2000s.

The Delta 2 traces its heritage back to the Thor missile from the Cold War era.

One more Delta 2 is set to launch from Vandenberg in September 2018 with NASA's ICESat 2 mission.

Orbital ATK Supports Launch of ULA's Delta II Rocket

Nine Orbital ATK Solid Rocket Motors Help Boost JPSS-1 to Orbit

Dulles, Virginia 20 November 2017 – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, contributed to the successful launch of a United Launch Alliance Delta II rocket as it lifted off Saturday from Vandenberg Air Force Base, California, carrying the first Joint Polar Satellite System (JPSS-1) spacecraft. Orbital ATK's contributions to the Delta II include nine Graphite Epoxy Motors (GEM 40) and a large composite fairing for the rocket. This event marks the penultimate launch of the Delta II rocket. It is also the last launch to use nine GEM 40 motors.

Спойлер

"As the Delta II program nears its retirement, more than 1,020 GEM 40 strap-on boosters have helped launch 153 Delta II missions," said Charlie Precourt, Vice President and General Manager of Orbital ATK's Propulsion Systems Division. "We'd be nostalgic if not for the significant progress we're already making on the new generation GEM 63 motor that will support Atlas V and future launch vehicles."

The nine GEM 40 motors used today, which is the maximum number for the Delta II design, provided an additional 1.3 million pounds of maximum thrust to boost ULA's Delta II launch vehicle on its successful mission. Orbital ATK manufactured the motors' composite cases in Clearfield, Utah, and the motors themselves in Magna, Utah.

In addition to the GEM 40 motors, Orbital ATK manufactured the composite 10-foot diameter payload fairing, which encapsulates and protects the payload, at its facility in Iuka, Mississippi. Orbital ATK also designed and built the launch vehicle's second stage helium and nitrogen pressurization bottles at its facility in Commerce, California.

For the JPSS-1 spacecraft, Orbital ATK manufactured the diaphragm propellant tank at its Commerce facility. The company also designed and produced heat pipes for two instruments aboard the satellite at its facilities in Beltsville, Maryland.

The Joint Polar Satellite System (JPSS) is a collaborative venture between NASA and NOAA. It will monitor existing environmental conditions such as temperature, vegetation, snow and ice cover, and ozone. JPSS will also enable forecasters to more accurately predict severe weather patterns and storm systems. JPSS-1 will be renamed NOAA-20 after it successfully reaches orbit. Orbital ATK's Space Systems Group is now designing and building the JPSS-2 spacecraft with options to build JPSS-3 and -4 spacecraft in the future.

November 21, 2017 (https://spaceflightnow.com/2017/11/) Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

Launching from Vandenberg Air Force Base on California's Central Coast on its third try, United Launch Alliance's Delta 2 rocket lifted off Saturday with NOAA's JPSS 1 polar-orbiting weather satellite.

Спойлер

It was the 154th and second-to-last flight of a Delta 2 rocket, the workhorse for NASA's interplanetary exploration program, climate and weather satellites, and a host of commercial and military missions in the 1990s and 2000s.

The 128-foot-tall (39-meter) Delta 2 rocket took off at 1:47 a.m. PST (4:47 a.m. EST; 0947 GMT) Saturday from Space Launch Complex 2-West at Vandenberg.

ЦитироватьJPSS-1 Has a New Name: NOAA-20
Nov 21, 2017

(https://img.novosti-kosmonavtiki.ru/209289.jpg)

JPSS-1 not only reached polar orbit on Saturday, November 18; it also officially became known as NOAA-20.

Спойлер

Traditionally, when NOAA's polar-orbiting satellites were planned, designed and built, NOAA assigned each one with a letter (-A, -B, -C ...). Then, when the satellite reached orbit after launch, it was given a number. For example, the polar-orbiting satellite NOAA-H launched on September 24, 1988. When it reached polar orbit, it became known as NOAA-11.

The polar-orbiting satellites of the Joint Polar Satellite System (JPSS-1, -2, -3, and -4) are a bit different. Instead of letters, they are designated by numbers during their construction, testing, and launch phases. However, they still become NOAA-20, -21, -22, and -23 when they attain orbit.  NOAA-20 takes its historical place in the sky as a next generation satellite with significant imaging capability improvements from its predecessors.

Why will their names change from "JPSS" to "NOAA"? According to NOAA documentation, the change is to maintain consistency in naming conventions that NOAA has followed since 1978 for polar-orbiting satellites.

Except for the NOAA-NASA Suomi National Polar-orbiting Partnership satellite (Suomi NPP), which was developed as a joint research mission and therefore not renamed a numbered NOAA satellite when it reached orbit, NOAA's satellites are typically built in sets or series. 

Now that JPSS-1 has reached polar orbit, the satellite's designation has been transitioned to NOAA-20. However, the entire series of satellites, of which JPSS-1 is the first, is still referred to as the JPSS series.

Forty-eight days after JPSS-1 (NOAA-20) was launched into Earth orbit, it sent back its first Cross-track Infrared Sounder (CrIS) science data. This data is a part of a series of instrument activation and checkout tests that occur before the satellite is declared fully operational. CrIS is one of five key instruments onboard NOAA-20 that will improve day-to-day weather forecasting while extending the record of many long-term observations of Earth's climate.

National Oceanic and Atmospheric Administration (NOAA) объявила о том, что она успешно активировала расположенные на КА Joint Polar Satellite System 1 (JPSS 1, NOAA 20) пару произведенных Northrop Grumman инструментов. Данная процедура последовала вслед за тем, как запущенный 18 ноября 2017 года с базы Ванденберг космический аппарат достиг заданной орбиты. Получаемая с приборов информация позволит агентству продолжать сбор данных о температурных профилях в пределах от земной поверхности до 45 км над уровнем моря, а также собирать информацию распределении водяного пара, отраженном Землей солнечном свете и термальном излучении. Как ожидается, получаемые данные позволят существенно нарастить точность предсказаний появления ураганов.

What Happens After Launch: Two NASA Educational CubeSats

A small group of students recently got to experience a rare, spaceflight thrill: seeing if the tiny satellite, called a CubeSat, they designed and built not only survived a rocket launch to space but also successfully gathered and transmitted data once on orbit.

The educational CubeSat missions were sel ected through the CubeSat Launch Initiative as part of the 14th installment of NASA's Educational Launch of Nanosatellites (ELaNa) missions. The ELaNa XIV mission was an auxiliary payload on the Nov. 18, 2017, launch of the Joint Polar Satellite System-1 satellite (now NOAA-20), a collaborative effort between the National Oceanic and Atmospheric Administration (NOAA) and NASA.

One CubeSat launched fr om the JPSS-1 rocket, RadFxSat, is a partnership between students at Vanderbilt University, Nashville, Tennessee, and AMSAT, a worldwide group of amateur radio operators. The Vanderbilt team built the science payload while AMSAT did the integration onto their own CubeSat platform. Their experiment is designed to obtain early on-orbit data in support of modeling radiation effects in a commercial memory, currently used for consumer electronics.

So far the project is successfully sending back data. "Because we partnered with the company donating the memory, there were engineering challenges to make sure we could communicate with the memory properly. I learned about power allocation and making sure the memories were within their power budget. I didn't realize how important power was for a spacecraft until I had to do it myself," said Rebekah Austin, a graduating Ph.D. student in electrical engineering at Vanderbilt. Austin is also a returning engineering summer intern at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Meanwhile, another CubeSat project, called EagleSat-1, is working through post-launch challenges. "It turns out we are not getting data back. There is still learning occurring, which is our main reason for doing the program. The students are learning the process of failure analysis and understanding the spacecraft a little bit better as a result of trying to figure out what could have gone wrong and try to figure out if there is anything we can do while it is on orbit," said Dr. Gary Yale, associate professor of aerospace engineering and faculty mentor for EagleSat-1, at Embry-Riddle Aeronautical University in Prescott, Arizona.

One possibility under consideration by the team of undergraduate researchers is that their antenna did not deploy after launch. The EagleSat-1 team hopes that if that is the problem, eventually the fishing line holding the antenna down will decay due to ultraviolet radiation in the space environment, causing the line to break and deploy the antenna, which was the backup plan for that eventuality.

"It is disappointing we haven't gotten data yet, and everyone is trying to make contact with it," said Deborah Jackson, an undergraduate and project manager for EagleSat-1. "We've passed down our lessons learned to our next project, EagleSat-2." EagleSat-1 has two functions, one is to track the satellite orbit as it decays over time and the second is to study the use of super capacitors in space as an alternative to traditional batteries, which rely on chemical reactions.

The results fr om these two NASA ELaNa CubeSat projects illustrates the program's function as an educational platform. "It is a way to pull kids into practical science application. I've seen junior and senior high kids building these things too," said Rex Engelhardt, NASA's ELaNA XIV mission manger and a launch services program mission manager, based at Kennedy Space Center in Florida. The process begins with a proposal that is competitively selected. Each group funds the building of their spacecraft, and NASA provides a ride to space using available capacity on NASA rockets.

"For JPSS-1, we had to assure them we were tracking the design, build and testing of these spacecraft and would not negatively impact the JPSS-1 satellite," Engelhardt said. After the primary satellite is released and sent on its way, then the CubeSats are released. Each CubeSat group is responsible for shock and vibration tests to prove their satellite can survive the launch.

"The teams were a lot of fun to work with, and they are excited about what they are doing," Engelhardt said. "We have a mission readiness review, wh ere they bring a briefing package which includes all their designs, how they built the spacecraft and met the requirements. We ask hard questions and challenge them in each three- to four-hour presentation. It is fun watching the different teams and personalities. One presenter drove in during his college break and did his presentation while munching an apple. We let him know that's not a good idea."

While the ELaNA CubeSat teams work through various stages of science and engineering challenges to get their CubeSats ready for flight, at the end it is about the learning process. "Motivating people to work to a common goal to stay focused on a project and complete it, is a huge educational win," Engelhardt said.
