SpaceX’s next Falcon 9 rocket arrived at Kennedy Space Center’s pad 39A on Thursday for a hold-down engine firing ahead of launch next week with the U.S. Air Force’s X-37B spaceplane. The brief engine ignition occurred at 4:30 p.m. EDT (2030 GMT).

These photographs span activities in March as the news media got an up-close viewing of the Orbital ATK commercial Cygnus cargo ship, its placement aboard a mobile transporter and delivery of the craft to the United Launch Alliance Atlas 5 rocket assembly building for hoisting and mating. Liftoff is scheduled for April 18.

The U.S. Air Force’s next GPS navigation satellite met its ride into space this week with the spacecraft’s bolting on top of a United Launch Alliance Delta 4 rocket at Cape Canaveral in preparation for liftoff Aug. 22.
