Watch the Falcon 9 launch from pad 39A

SpaceX lofted another batch of Starlink internet satellites into orbit on Friday from Vandenberg Space Force Base in California. A Falcon 9, with 48 satellites inside its payload fairing, lifted off at 12:29:50 p.m. PDT (3:29:50 p.m. EDT; 1929:50 UTC) from Space Launch Complex 4-East.

Nine Merlin main engines on a SpaceX Falcon 9 rocket ignited at 12 p.m. EDT (1600 GMT) Friday, April 17, during a hold-down test-firing on launch pad 39A at NASA’s Kennedy Space Center in Florida.

Orbital Sciences Corp. announced Tuesday it selected United Launch Alliance’s Atlas 5 rocket to launch a Cygnus space station resupply mission in late 2015 while the company redesigns its Antares booster with a new engine following a catastrophic failure seconds after liftoff in October.
