A SpaceX capsule sent to bring back two astronauts stranded on the International Space Station (ISS) has docked.
The Dragon capsule has two empty seats for Butch Wilmore and Suni Williams, who were only meant to be on the ISS for eight days, but were forced to remain there because of a fault discovered during the flight. The pair are now expected to return to Earth in February.
The Dragon capsule lifted off from Cape Canaveral, Florida on Saturday carrying Nasa astronaut Nick Hague and Russian cosmonaut Alexander Gorbunov.
