Live coverage: Falcon 9 disintegrates after launch

The access arm astronauts will transit when boarding SpaceX’s Crew Dragon commercial capsule has arrived at launch pad 39A at the Kennedy Space Center in Florida.

A SpaceX Falcon 9 rocket, built with extended propellant tanks and engines rated for higher thrust, is poised for liftoff on the company’s first launch since a catastrophic failure in June grounded the commercial booster.

SpaceX’s first partially-assembled Starship vehicle, originally built for atmospheric test flights, ruptured in dramatic fashion Wednesday during a cryogenic loading test at the company’s launch facility in South Texas.
