A SpaceX Falcon 9 rocket launched at 4:25 p.m. EST (2125 GMT) on 31 January from Cape Canaveral with the GovSat 1 communications satellite.

Juggling simultaneous launch campaigns on both coasts, a team of SpaceX engineers put a Falcon 9 rocket through a customary countdown rehearsal and hold-down firing Tuesday at Vandenberg Air Force Base in California ahead of a scheduled liftoff Sunday.

Six years after launching for the first time, a Russian Angara A5 heavy-lift rocket took off on its second test flight Monday and successfully delivered a dummy payload into orbit.
