Watch the Falcon 9 launch from pad 39A

The mission features orbital transfer vehicles that are carrying 30 of the payloads with 14 being deployed after the initial mission launch. Liftoff from pad 4 East at Vandenberg Space Force Base happened at 10:49 a.m. PST (1:49 p.m. EST, 1849 UTC).

Six days after SpaceX fired its last Falcon 9 rocket from NASA’s Kennedy Space Center, another launcher rolled to historic pad 39A and ignited its nine Merlin 1D engines at sunset Thursday in preparation for a commercial satellite delivery mission Sunday for Intelsat.

Orbital ATK’s Antares rocket will deliver the commercial Cygnus supply ship to an orbit with an altitude between 117 miles (189 kilometers) and 184 miles (296 kilometers) within about nine minutes of liftoff Saturday from Virginia’s Eastern Shore.
