The first flight of SpaceX’s Dragon capsule

The quartet touched down at the Launch and Landing Facility around 1:45 p.m. EST (1845 UTC). They’re set to launch aboard a SpaceX Falcon 9 rocket on Friday, March 1, at 12:04 a.m.

SpaceX’s Falcon 9 booster accomplished a delicate maneuver after a glowing predawn launch from Cape Canaveral on Saturday, autonomously navigating its away to a modified barge the size of a football field hidden in darkness beneath a blanket of low clouds, before it crashed and broke apart.

Running through a practice countdown and hold-down engine firing at NASA’s Kennedy Space Center, a SpaceX Falcon 9 rocket passed a key checkpoint Thursday ahead of liftoff next week with the U.S. Air Force’s fifth X-37B spaceplane flight, a mission that will come with several firsts.
