Watch the Falcon 9 launch from pad 39A

The astronauts assigned to fly SpaceX’s Crew Dragon spacecraft beginning later this year said Friday they are excited for the capsule’s first orbital mission set for launch Saturday, but significant work remains before the ship is cleared to carry people.

SpaceX test-fired a Falcon 9 rocket Friday at Cape Canaveral in preparation for liftoff as soon as Sunday with the company’s fifth batch of Starlink broadband satellites.

New video released by the Russian space agency Thursday shows the moment a Soyuz rocket ran into trouble around two minutes after liftoff with a two-man crew Oct. 11, when one of the vehicle’s four first stage boosters crashed into the Soyuz core stage.
