SpaceX and NASA are targeting a launch no earlier than Friday for the Crew-10 mission to the International Space Station to relieve Starliner astronauts Butch Wilmore and Suni Williams after Wednesday’s attempt was scrubbed due to a launch pad issue.

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.

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.
