Watch the Falcon 9 launch from pad 39A

SpaceX said Sunday that the first Falcon 9 rocket launch from pad 39A, a former shuttle-era complex at NASA’s Kennedy Space Center in Florida, is scheduled to send a Dragon supply ship to the International Space Station in mid-February, deferring a mission with an EchoStar communications satellite that was set to take off this month.

SpaceX ran a Falcon 9 rocket through a customary preflight checkout Tuesday, filling it with super-cold propellants and firing its nine Merlin first stage engines in preparation for liftoff Friday on a resupply run to the International Space Station.

SpaceX’s Dragon spaceship, carrying more than 4,100 pounds of cargo and research specimens, descended to a predawn splashdown Monday in the Pacific Ocean southwest of Los Angeles, completing the first re-flight of one of SpaceX’s unpiloted supply ships to the International Space Station.
