A United Launch Alliance Atlas 5 successfully launched the fourth in a series of military mobile communications satellites Wednesday. The Atlas 5 551 lifted off from Cape Canaveral at 6:18 am EDT (1018 GMT) Wednesday and released the MUOS-4 satellite into geostationary transfer orbit nearly three hours later. The launch had been delayed two days because of weather, and took place nearly 20 minutes late Wednesday because of a brief glitch with ground equipment. The satellite is the fourth in the Mobile User Objective System, which provides mobile communications for military forces.
