The U.S. space agency and SpaceX are on a mission to bring home astronauts Butch Wilmore and Suni Williams. They have been stuck on the International Space Station for nine months.

SpaceX has launched a rocket carrying a new crew to the International Space Station (ISS) as part of a plan to bring astronauts Butch Wilmore and Suni Williams home. The pair were due to be on the ISS for only eight days,

The delayed mission must reach the space station before the two astronauts who've been "stuck" in space can return home.

SpaceX launched a crew to the International Space Station on Friday, a closely watched mission that would allow marooned astronauts Butch Wilmore and Suni Williams to finally return home.
