Watch the Falcon 9 launch from pad 39A

The mission came a little more than 12 hours after SpaceX performed a static fire test of the rocket Monday night. Liftoff of the Starlink 10-5 mission happened at 9:20 a.m. EDT (1320 UTC).

On the eve of the 10th anniversary of the Falcon 9 rocket’s debut flight, SpaceX launched a Falcon 9 from Cape Canaveral with a reused first stage Wednesday, then landed the previously-flown booster for a record fifth time after sending 60 more Starlink Internet satellites into space.

SpaceX, the upstart rocket company that has shaken up the launch industry with low-cost reusable boosters and ambitious long-range plans to carry people to Mars and beyond, plans to reduce its workforce by about 10 percent, company sources said late Friday.
