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