NASA has finally set a return date for its stranded astronauts – and it seems the pair don’t have long to wait to come back to Earth.

Veteran astronauts Butch Wilmore and Suni Williams were due to spend eight days on the International Space Station (ISS) but have been there for more than eight months after their Boeing Starliner spacecraft suffered propulsion problems.

Although their return craft has been docked with the station since September, Williams and Wilmore have been stuck while NASA prepares to send their replacements in the Crew 10 mission.

The mission was originally pushed back to late March, but the space agency now says it is ‘accelerating’ the launch to target Wednesday, March 12.

Crew 9, which includes Williams and Wilmore, will then spend a few days handing over to the new arrivals before making their way back to Earth.

The mission is scheduled to launch ‘pending mission readiness’, but further delays are possible if there is not an appropriate weather window.

Steve Stich, manager of NASA’s Commercial Crew Program, says: ‘Human spaceflight is full of unexpected challenges.

‘Our operational flexibility is enabled by the tremendous partnership between NASA and SpaceX and the agility SpaceX continues to demonstrate to safely meet the agency’s emerging needs.’

Wilmore and Williams first arrived at the ISS on June 5 last year aboard the Boeing Starliner spacecraft but became stranded after the experimental craft developed serious issues.

By the time the capsule arrived at the station, it had sprung a number of helium leaks, and five of its 28 thrusters had failed.

After weeks of tests, NASA ultimately decided that Starliner wasn’t safe enough to carry humans back to Earth and in September, the doomed spacecraft was sent home empty.

The SpaceX Crew Dragon spacecraft they are scheduled to return on arrived later that month, but the pair must wait until March to use it.

Since Williams and Wilmore have become official members of NASA’s Crew 9 mission, they must wait to hand over with Crew 10 before leaving the station.

Originally, the Crew 10 mission was due to launch in February aboard a brand-new SpaceX Crew Dragon capsule.

However, the mission had to be delayed when it emerged that SpaceX was not able to complete the construction and testing of the new capsule on time.

NASA explains that this latest scheduling change comes after SpaceX agreed to use a Crew Dragon capsule called Endurance which has already been used three times.

Boeing’s Starliner spacecraft was plagued by technical issues even before it launched. By the time it arrived at the ISS, it had sprung more helium leaks and five of its 28 thrusters had failed, leaving Williams and Wilmore stranded

SpaceX and NASA are now working together to assess the spacecraft’s hardware, refurbish the interior, and get it ready for flight.

The capsule will launch with NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov.

Crew 10 will then meet with Williams and Wilmore on the ISS for a brief handover period window in which they will be familiarised with ongoing scientific and maintenance projects.

Finally, Crew 9 will return home with NASA astronauts Butch Wilmore, Suni Williams, and Nick Hague alongside Roscosmos cosmonaut Aleksandr Gorbunov.

Pending good weather conditions, the capsule should splash down off the coast of Florida.

This announcement comes after Donald Trump called for SpaceX CEO Elon Musk to ‘go get’ the stranded astronauts and blamed delays on former president Joe Biden.

In a statement posted to his Truth Social platform, Trump wrote: ”I have just asked Elon Musk and SpaceX to “go get” the two brave astronauts who have been virtually abandoned by the Biden administration.’

He added: ‘Elon will soon be on his way. Hopefully, all will be safe. Good luck Elon!!!’

Having now become part of the NASA Crew 9 mission, Williams (pictured) and Wilmore must wait until the Crew 10 mission arrives so that they can hand over to their replacement crew

The mission to collect the stranded astronauts has been accelerated after SpaceX agreed to use a previously used Crew Dragon capsule rather than a new spacecraft which was not going to be ready in time

This comes after SpaceX CEO Elon Musk (left) and Donald Trump (right) created confusion by claiming that Musk had been ordered to ‘go get’ the stranded astronauts, despite the mission being planned for months in advance

In response, Musk tweeted: ‘The @POTUS has asked @SpaceX to bring home the 2 astronauts stranded on the @Space_Station as soon as possible. We will do so.

‘Terrible that the Biden administration left them there so long.’

These statements spread widespread confusion on social media given that SpaceX had been tasked with bringing the pair home months ago by Biden administration.

Likewise, despite the most recent delays being caused by SpaceX, Musk has been quick to celebrate the accelerated timeline.

In a post on X Musk wrote: ‘They’re coming home.’

In January, Wilmore and Williams said their spirits were still high, adding that they had plenty of food and were enjoying their time on the space station.

Yet there has been growing concern for the pair’s health after images appeared to show Williams looking thin and gaunt.

Williams has pushed back against the claims, blaming her appearance of unusual fluid distribution in microgravity and claiming that she has actually gained muscle in her legs.

Pictures of mission commander Williams have since sparked health concerns due to her ‘gaunt’ appearance. Williams maintains that she has actually gained weight while in space and that her unusual appearance is due to ‘fluid shift’

But, in January, Williams admitted that she had forgotten what it was like to walk after 234 days in space.

‘I’ve been up here long enough, right now I’ve been trying to remember what it’s like to walk. I haven’t walked. I haven’t sat down. I haven’t laid down,’ she said during a video call with students at Needham High School in Massachusetts.

However, NASA maintains that their astronauts are trained for extended stays in space and that some deterioration of muscle function is entirely normal.

If Williams and Wilmore do return home in late March as expected, their mission will have lasted two months longer than a standard long-term ISS mission, which typically lasts six months.

While their protracted stay is notable, it has not yet surpassed Frank Rubio’s record-breaking 371 days aboard the ISS, which he completed in 2023 after the Russian spacecraft designated for his return developed a coolant leak.
