Astronauts Butch Wilmore and Suni Williams welcome SpaceX capsule that will bring them back to earth
The two astronauts stuck at the International Space Station since June have welcomed their new ride home with the arrival of a SpaceX capsule.
SpaceX launched the rescue mission on Saturday with a downsized crew of two astronauts and two empty seats reserved for Butch Wilmore and Suni Williams, who will return in 2025.
The Dragon capsule docked in darkness on Sunday high over Botswana as the two craft soared 420km above Earth.

It was the first Starliner test flight with a crew, and NASA decided the thruster failures and helium leaks that cropped up after lift-off were too serious and poorly understood to risk the test pilots’ return. So Starliner returned to Earth empty earlier in September.
The Dragon carrying NASA’s Nick Hague and the Russian Space Agency’s Alexander Gorbunov will remain at the space station until February, turning what should have been a wee-long trip for Wilmore and Williams into a mission lasting more than eight months.
Two NASA astronauts were pulled from the mission to make room for Mr Wilmore and Ms Williams on the return leg.
NASA likes to replace its station crews every six months or so. SpaceX has provided the taxi service since the company’s first astronaut flight in 2020.
NASA also hired Boeing for ferry flights after the space shuttles were retired, but flawed software and other Starliner issues led to years of delays and more than $US1 billion ($A1.4 billion) in repairs.
Starliner inspections are under way at NASA’s Kennedy Space Center, with post-flight reviews of data set to begin this week.
“We’re a long way from saying, ‘Hey, we’re writing off Boeing,’” NASA’s associate administrator Jim Free said at a pre-launch briefing.
The arrival of two fresh astronauts means the four who have been up there since March can return to Earth in their own SpaceX capsule in just over a week. Their stay was extended a month because of the Starliner turmoil.
Although Saturday’s lift-off went well, SpaceX said the rocket’s spent upper stage ended up outside its targeted impact zone in the Pacific because of a bad engine firing. The company has halted all Falcon launches until it figures out what went wrong.
