Four Northrop Grumman Corporation 63-inch-diameter Graphite Epoxy Motors (GEM 63) solid rocket boosters have helped successfully launch and deploy the National Oceanic and Atmospheric Administration’s (NOAA) Geostationary Operational Environmental Satellite T (GOES-T) aboard a United Launch Alliance (ULA) Atlas V rocket. The GEM 63 boosters provided approximately 1.5 million pounds of additional maximum thrust at launch, with each motor contributing approximately 375,000 pounds of thrust. Northrop Grumman also produced the composite heat shield, the Centaur interstage adapter and the boattail on the ULA Atlas V launch vehicle.
