Four astronauts will soon launch to the space station — a flight that will kick off a series of events culminating in the long-awaited return of NASA astronauts Suni Williams and Butch Wilmore.

Update: NASA and SpaceX have postponed the launch, according to posts on X. NASA and SpaceX will launch the Crew-10 mission to retrieve astronauts Suni Williams and Butch Wilmore from the International Space Station on Wednesday evening.

A launch pad problem prompted SpaceX to delay a flight to the International Space Station on Wednesday to replace NASA's two stuck astronauts. The new crew needs to get to the International Space Station before Butch Wilmore and Suni Williams can head home after nine months in orbit.
