The mission was launched from Cape Canaveral Air Force Station in Florida by a United Launch Alliance Delta IV rocket. Aerojet Rocketdyne propulsion included an RS-68A booster engine and an RL10B-2 upper-stage engine, 12 helium pressurant tanks and 12 reaction control thrusters on the upper stage for roll, pitch, yaw and settling burns.
