Live coverage: Falcon 9 disintegrates after launch

With this launch, SpaceX is now one flight shy of tying the total number of Space Shuttle missions from this historic launch pad. This was the 81st flight of a Falcon rocket compared to the 82 total shuttle flights. Liftoff of the Starlink 6-51 mission happened at 5:26 p.m. EDT (2126 UTC).

The Russian Progress 58P cargo freighter launches and six hours later docks to the International Space Station.

The National Reconnaissance Office has confirmed it will launch a payload on a SpaceX Falcon 9 rocket from Cape Canaveral later this month, a mission on SpaceX’s schedule that was not publicly disclosed until recently.
