Photos: Falcon takes flight

Take a look back at the Dec. 22 liftoff of a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California, a launch that was visible across Southern California and as far away as Arizona as the booster climbed into sunlight at dusk to deliver 10 commercial communications satellites to orbit.

The Starlink 17-9 mission added another 24 broadband satellites to its low Earth orbit constellation of more than 8,300. Liftoff from pad 4E at Vandenberg Space Force Base happened at 11:06 a.m. PDT (2:06 p.m. EDT / 1806 UTC).

SpaceX’s Falcon Heavy rocket rolled out of its hangar and up the ramp to pad 39A at NASA’s Kennedy Space Center in Florida, then was raised vertical at the seaside launch complex early Monday in preparation for a late-night liftoff with two dozen weather observation and technology demonstration satellites.
