MUOS 5 is scheduled for launch from CCAFS on an Atlas V-551 on 2016 Jun 24; the launch window is from 14:30 to 15:14 UTC. Spaceflight Now will provide live coverage: http://spaceflightnow.com/2016/06/23/av063_journal/ The following *rough* TLEs are based on launch at window-open.

Spacecraft separation is planned to occur at T+2:53:18. Soon afterward, the Centaur will perform a Collision and Contamination Avoidance Maneuver (CCAM), followed by a blow-down of remaining Centaur propellants. The typical Centaur end of mission occurs 4400 s after spacecraft separation. Prospective observers should use the MECO 3 TLE to evaluate visibility. Eventually, the payload will enter an approximately 5 deg inclined GEO orbit in one of the existing UFO slots.
