The hardware that will fly SpaceX's next astronaut mission for NASA is poised and ready for liftoff.

The Crew-5 mission is scheduled to launch at noon EDT (1600 GMT) on Wednesday (Oct. 5) from Pad 39A at NASA's Kennedy Space Center (KSC) in Florida, and team members have been checking off boxes in the leadup.

On Saturday (Oct. 1), for example, the four Crew-5 astronauts — NASA's Nicole Mann and Josh Cassada, Japan's Koichi Wakata and Russian cosmonaut Anna Kikina — arrived at KSC from NASA's Johnson Space Center in Houston.

SpaceX, NASA and the Crew-5 astronauts also "completed a full rehearsal of launch day activities" on Sunday, SpaceX said via Twitter (opens in new tab).

For instance, Kikina will become the first cosmonaut ever to fly on a SpaceX mission to orbit.
