SpaceX capsule begins rescue mission to return stranded astronauts

SpaceX has launched its mission to bring back two astronauts stranded on the International Space Station (ISS) since June.
The Dragon capsule, which has two empty seats for Butch Wilmore and Suni Williams, lifted off from Cape Canaveral, Florida on Saturday.

The pair's mission at the space station had only been expected to last about eight days but after a fault was found on the new Boeing Starliner it returned to Earth empty as a precaution.
