Time lapse: Watch the Falcon Heavy placed on pad 39A

The Starlink 6-88 added 29 broadband internet satellites to the constellation of more than 9,300 in low Earth orbit. Liftoff from pad 40 at Cape Canaveral Space Force Station happened at 1:48 a.m. EST (0648 UTC).

SpaceX says Sunday is the target launch date for the first launch of a remodeled version of its Falcon 9 rocket, and the launcher’s first mission since a June failure, after completing a practice countdown and engine ignition test Friday.

A Northrop Grumman Cygnus supply ship — named the S.S. Katherine Johnson for the trailblazing NASA mathematician portrayed in “Hidden Figures” — was loaded with time-sensitive cargo Friday at a launch pad in Virginia for a midday blastoff Saturday toward the International Space Station.
