Two astronauts stuck in space for more than nine months head back to E

Two astronauts stuck in space for more than nine months have left the International Space Station on their 17-hour journey back to Earth.

Butch Wilmore and Suni Williams blasted off to the ISS on 5 June, and were meant to be up there for just eight days.

They were testing out Boeing’s long-awaited Starliner, a ship designed to rival SpaceX’s Crew Dragon that is currently used to ferry astronauts into space.

But by the time they docked at the ISS, the Starliner had suffered major problems – with five helium leaks, five dead manoeuvring thrusters and a propellant valve that failed to close completely.

It returned to Earth without them, after it was decided the astronauts would be safer waiting in orbit.

Since then, the two US Navy veterans have completed spacewalks, experiments and even helped sort out the plumbing onboard.

The astronauts have repeatedly said they have enjoyed the mission, with Ms Williams describing the space station as her “happy place”.

“Every day is interesting because we’re up in space and it’s a lot of fun,” she said earlier this month, although she added the waiting was likely hard for family members on the ground.
