The rocket that will launch NASA's Crew-10 is on the pad. This comes after a spacecraft swap and Falcon 9 incidents required additional testing.

The company did not immediately announce a new launch date, but noted the next try could be as early as Thursday night.

NASA and SpaceX on Wednesday night scrubbed the Falcon 9 launch of a flight intended to retrieve from the International Space Station astronauts Suni Williams and Butch Wilmore, who have spent nine months in orbit.
