Live coverage: Falcon 9 disintegrates after launch

SpaceX’s Falcon 9 rocket ignited its nine Merlin main engines for several seconds Thursday at launch pad 39A in Florida, moving the previously-flown booster closer to a scheduled blastoff Monday with a Bulgarian communications satellite.

Watch a Falcon 9 rocket lift off from Cape Canaveral on December 8, 2010, at 10:43 a.m. EST (1543 GMT) on the COTS (Commercial Orbital Transportation Services) Demo Flight 1. It was the first test flight of the Dragon cargo ship.

The Starlink 11-20 mission saw SpaceX’s Falcon 9 rocket fly on a south-easterly trajectory upon departure from Vandenberg Space Force Base. Liftoff from pad 4E happened at 7:04 p.m. PDT (10:04 p.m. EDT / 0204 UTC).
