Atlas Speeds U.S. Navy's Latest Spacecraft into Orbit

The third time was the charm for NASA and the U.S. Navy.

After weather scrubbed two launches last week, an Atlas 5 rocket carrying the Navy's newest generation of mobile communications spacecraft -- the Mobile User Objective System-1 (MUOS-1) -- got off the ground just after 5:15 p.m. Friday.

The launch marked the 200th flight of the Centaur upper stage.
