Environmental testing underway for JPSS 1 launching in January

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.

Спойлер
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 mission and to provide data continuity between the EOS Terra and Aqua missions and the NPOESS 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 sensors.
Ball Aerospace will employ a modified BCP-2000 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 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 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 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
by Jeff Foust — August 5, 2016

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.

September 6, 2017 Justin 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:

The Advanced Technology Microwave Sounder (ATMS)
    – Atmospheric water vapor, temperature and pressure profiler
    – Built by Northrop Grumman
 The Visible/Infrared Imager Radiometer Suite (VIIRS)
    – Visible and infrared imagery and take sea-surface temperatures
    – Built by Raytheon
 The Cross-track Infrared Sounder (CrIS)
    – Hyperspectral sounder for atmospheric temperature and moisture
    – Built by Harris Corporation
 The Ozone Mapping and Profiler Suite (OMPS)
    – Monitor concentration of ozone in the Earth's atmosphere
    – Built by Ball Aerospace
 The Clouds and the Earth Radiant Energy System (CERES)
    – Reflected sunlight and Earth thermal radiation measurements
    – Built by NASA's Langley Research Center

JPSS 1 will replace the existing Suomi NPP spacecraft that launched in 2011 as a gapfiller between NOAA's legacy weather satellite constellation and the new JPSS generation.

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.

NOAA's JPSS-1 satellite arrived Sept. 1 at the Astrotech Processing Facility at Vandenberg, where it is undergoing final steps toward encapsulation in the protective payload fairing. The Delta II rocket is in place at Space Launch Complex-2, awaiting the arrival of the fairing at the launch site.

NOAA partnered with NASA to implement the JPSS series of U.S. civilian polar-orbiting environmental remote sensing satellites and sensors. JPSS-1 has a seven-year design life and is the first in a series of NOAA's four next-generation, polar-orbiting weather satellites.
