Aerojet Rocketdyne Supports ULA Delta II Launch of Joint Polar Satellite System-1
November 18 2017 - 8:29AM
Aerojet Rocketdyne, Inc., a subsidiary of Aerojet Rocketdyne
Holdings, Inc. (NYSE:AJRD), helped propel the United Launch
Alliance Delta II rocket, carrying the Ball Aerospace-built
JPSS-1 satellite, the first of the new JPSS (Joint Polar Satellite
System) constellation, into orbit for the National Oceanic and
Atmospheric Administration (NOAA) and NASA. The mission will
provide sophisticated meteorological data and observations of
atmosphere, ocean and land to help NOAA’s National Weather Service
improve the 3 to 7 day weather forecasts aiding emergency personnel
in pre-storm preparation. JPSS-1 launched from Vandenberg Air Force
Base in California. Aerojet Rocketdyne propulsion included an
RS-27A engine system and an AJ10-118K upper-stage engine.
“The RS-27A and AJ10-118K engines continue Aerojet Rocketdyne’s
strong legacy of placing critical satellites into orbit with
100 percent mission success,” said Aerojet Rocketdyne CEO and
President Eileen Drake. “It’s an honor to know we are helping to
support climate research, weather and storm prediction for civil,
military and international partners. Congratulations to everyone
involved.”
Aerojet Rocketdyne’s role in the launch began during liftoff
when the RS-27A engine ignited to provide 237,000 pounds of
vacuum-level thrust to launch the Delta II rocket. The RS-27
family of engines has compiled one of the most consistent and
successful launch records in the history of rocketry, with 240
launches since 1974.
After separation of the first stage, the AJ10-118K upper-stage
engine ignited to place the payload into orbit, providing
approximately 10,000 pounds of vacuum thrust for orbital insertion.
The AJ10 family of engines has provided second-stage propulsion for
more than 270 Delta flights, with 100 percent mission
success.
The RS-27A and AJ10-118K engines have helped place payloads into
space aboard the Delta II launch vehicle for the U.S. Air
Force, NASA and commercial spacecraft missions, including the
Phoenix Mars Lander, Deep Impact, Kepler, NEAR Shoemaker and the
Mars Exploration Rovers, Spirit and Opportunity, as well as the
U.S. Air Force Global Positioning Block IIR fleet.
The JPSS next-generation polar-orbiting, non-geosynchronous
satellites will circle the Earth from pole-to pole and cross the
equator about 14 times per day, providing full global coverage
twice a day, according to NOAA. It is a collaborative program
between NOAA and NASA. The JPSS constellation will carry a suite of
sensors designed to collect measurements of atmospheric,
terrestrial and ocean conditions, including clouds, rainfall, snow
and ice cover, vegetation, fire location, water vapor and ozone, as
well as sea and land surface temperatures.
