Russia's Rassvet fleet loses first satellite

Object 4, one of 16 satellites in Russia's Rassvet broadband network, re-entered Earth's atmosphere around June 6 after failing to perform any orbit-raising maneuvers. The satellite launched March 23 from Plesetsk Cosmodrome and decayed from a 288km x 324km insertion orbit. Six other satellites slowly climb while eight hold altitude. The cause of Object 4's failure is unconfirmed but could be a dead propulsion system or loss of ground control.
