NASA will wait at least another two days to launch its next space station crew, delaying the return of Starliner astronauts Barry "Butch" Wilmore and Sunita Williams a bit longer.

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.

After being stranded in space for nine months, two NASA astronauts are getting closer to finally returning to Earth as a new group of astronauts prepare to head to the International Space Station.

Sunita Williams and Barry “Butch” Wilmore were meant to spend about a week in space. They’ve been stuck for nine months — but may soon be on their way home.

A replacement crew is heading to the ISS, and Suni Williams and Butch Wilmore will come home at last. But first, another delay.

SpaceX launch scheduled for Wednesday will carry replacement crew for astronauts who have been stuck on the International Space Station since their troubled Starliner mission.
