"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 (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-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.

RELEASE 17-086

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


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.

"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.

Delta 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.

Penultimate Delta 2 rocket launch lofts advanced polar-orbiting weather satellite
November 18, 2017 Stephen Clark

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.

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



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.
