Astronauts could be stuck in space for eight months, Nasa says

Nasa has given an update on two American astronauts who are stuck on the International Space Station (ISS), Astronauts Sunita Williams and Barry 'Butch' Wilmore, who launched into space on 5 June for a mission expected to last eight days - they've been in space for more than two months.

The spacecraft that took them there - Boeing's Starliner – has faced technical issues which has halted their return to Earth.

Nasa officials have said the duo could be in orbit for eight months if they can't return on the Starliner.

The Starliner is still the contingency vehicle if the astronauts need to return to Earth, Nasa officials said. The astronauts could return on SpaceX's Dragon, however, Nasa said this could pose other risks.
