(Telecompaper) The Russian space agency Roskosmos has announced that it has lost contact with an Angolan telecommunications satellite launched from the Baikonur Cosmodrome. Roskosmos said that the launch on 27 December was successful, but that ground control stopped receiving telemetric data from the satellite shortly after it entered orbit. In a brief statement, it said officials were trying to restore contact with Angosat-1, the African country's first telecommunications satellite.
