NASA and SpaceX are preparing to launch four astronauts to the International Space Station (ISS) on Wednesday night. The new astronauts will relieve the Crew-9 astronauts, who will head back to Earth a few days later after being stuck on the ISS for nine months.

Live updates Wednesday from NASA's SpaceX Crew-10 scrub and a Falcon 9 Starlink rocket liftoff from Cape Canaveral Space Force Station in Florida.

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.
