A SpaceX crew on a rescue mission have arrived at the International Space Station, but it will still be some time before stranded Boeing Starliner astronauts Butch Wilmore and Suni Williams can return back to Earth.

NASA decided using the Boeing Starliner capsule to bring Butch Wilmore and Suni Williams back to Earth was too risky following a string of technical glitches on their outwards journey.

When they return from the space station in February, they will bring back the two space veterans – Butch Wilmore and Suni Williams – whose stay on the ISS was prolonged for months by problems with their Boeing-designed Starliner spacecraft.
