GOES-S Launch Marks Flight of 100th Aerojet Rocketdyne AJ-60A Solid Rocket Booster
The AJ-60A is one of numerous
GOES-S is the second in a new generation of geostationary-orbiting weather satellites built under contract to NASA for the
new generation of satellites, the first of which launched in
"The GOES-R Series of satellites will save lives and property every year, particularly in areas prone to severe storms like hurricanes and tornadoes," said
The AJ-60A was designed specifically to augment the lifting power of the Atlas V,
which is used to launch most
The GOES-S launch utilized four AJ-60A SRBs, bookended by the 97th and 100th units to fly to date. "What's important to note about this milestone is that it was reached with 100 percent mission success," Drake said.
The Atlas V's Centaur upper stage, meanwhile, relies on Aerojet Rocketdyne's RL10C-1 engine, which generates 22,900 pounds of thrust to deliver payloads to orbit. Variants of this engine have been in use for five decades - 487 have flown to date - and are still relied upon today to launch the vast majority of operational
The Centaur upper stage also uses smaller

The 16 MR-401 LTRs, designed specifically for the next-generation GOES-R Series, debuted on GOES-R, now GOES-16, and are used to keep the satellites stabilized in orbit on their east-west axis. The MR-510 electric thrusters are used for north-south station keeping and to propel the satellite into a graveyard orbit, where it will not pose any threat to other spacecraft in the geostationary-orbit arc, at the end of its mission.
