Live coverage: Falcon 9 disintegrates after launch

SpaceX’s first Falcon Heavy rocket was loaded with propellants Saturday at Kennedy Space Center’s launch pad 39A, as engineers make progress preparing for a hold-down engine firing, and eventually liftoff of the huge commercial launcher.

With another SpaceX rocket poised for launch just a few miles away, a Falcon 9 launcher soared through a moonlit sky over Cape Canaveral on Feb. 4 carrying 60 more Starlink internet satellites into orbit.

United Launch Alliance scrubbed the launch of a Delta 4-Heavy rocket Wednesday night less than 10 seconds before liftoff from Cape Canaveral, the second such abort suffered by this mission.. The launch of a classified National Reconnaissance Office spy satellite is expected to be delayed at least several more days as engineers assess the cause of Wednesday’s last-minute abort.
