How beautiful. Just over one year ago: Atlas V launches MUOS-4 satellite into the pre-dawn sky, creating a spectacular display across Florida's Space Coast. The MUOS-4 spacecraft brought advanced, new, global communications capabilities to mobile military forces, as well as ensure continued mission capability of the existing Ultra High Frequency satellite communications system. This mission was launched aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) 551 configuration vehicle, which includes a 5-meter diameter payload fairing along with five Aerojet Rocketdyne solid rocket motors attached to the Atlas booster. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine and the Centaur upper stage was powered by the Aerojet Rocketdyne RL10C-1 engine.
