Video: Falcon 9 fires up engines on pad 39A (members only)

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.

A new Russian weather observatory and the first prototype for Telesat’s planned network of 100-plus broadband communications satellites in low Earth orbit were among 19 spacecraft feared lost after a Fregat rocket stage ran into trouble soon after liftoff aboard a Soyuz booster Tuesday.

Launch of the Starlink 11-9 mission carrying 27 satellites for SpaceX’s internet service slipped a day from Sunday to Monday. Liftoff from pad 4 East at Vandenberg Space Force Base happened at 1:42 p.m. PDT (4:42 p.m. EDT, 2042 UTC).
