NASA and SpaceX on Wednesday delayed the launch of a replacement crew of four astronauts to the International Space Station that would have set in motion the long-awaited homecoming of U.S. astronauts Butch Wilmore and Suni Williams.

SpaceX and NASA are aiming for a launch no earlier than Friday for a mission to relieve Starliner astronauts Butch Wilmore and Suni Williams, who have been in orbit for nine months.  The Crew-10 is now targeting a liftoff no earlier than Friday at 7:03 p.

A launch pad problem has forced a flight delay 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.
