Stranded astronauts will stay on space station until February, NASA says

Two U.S. astronauts who flew to the International Space Station in June aboard Boeing's faulty Starliner capsule will need to return to Earth on a SpaceX vehicle early next year, NASA said on Saturday.

Faulty Boeing spacecraft deemed too risky for return trip, so astronauts must wait for next SpaceX departure

Why 2 NASA astronauts are stuck on the International Space Station

Time is ticking for NASA to decide on how it's going to bring two American astronauts stuck on the International Space Station back to Earth. It's been three months since Butch Wilmore and Suni Williams went to space on Boeing's Starliner, which is now facing technical malfunctions that have, so far, prevented a return trip.

Two NASA astronauts who flew to the International Space Station (ISS) in June aboard Boeing's faulty Starliner capsule will need to return to Earth on a SpaceX vehicle early next year, NASA officials said on Saturday, deeming issues with Starliner's propulsion system too risky to carry its first crew home as planned.

Veteran NASA astronauts Butch Wilmore and Suni Williams, both former military test pilots, became the first crew to ride Starliner on June 5 when they were launched to the ISS for what was expected to be an eight-day test mission.

But Starliner's propulsion system suffered a series of glitches in the first 24 hours of its flight to the ISS that has so far kept the astronauts atthe station for 79 days as Boeing scrambled to investigate the issues.

NASA officials told reporters during a news conference in Houston that Wilmore and Williamsare safe and prepared to stay even longer. They will use their extra time to conduct science experiments alongside the station's other seven astronauts, NASA said.

In a rare reshuffling of NASA's astronaut operations, the two astronauts are now expected to return in February 2025 on a SpaceX Crew Dragon spacecraft that is due to launch next month as part of a routine astronaut rotation mission. Two of the Crew Dragon's four astronaut seats will be kept empty for Wilmore and Williams.

The agency's decision, tapping Boeing's top space rival to return the astronauts, is one of NASA's most consequential in years. Boeing had hoped the test mission would redeem the Starliner program after years of development problems and more than $1.6 billion US in budget overruns since 2016.

Five of Starliner's 28 thrusters failed during flight, and it sprang several leaks of helium, which is used to pressurize the thrusters. It was still able to dock with the station, a football field-sized laboratory that has housed rotating crews of astronauts for more thantwo decades.

NASA said in a statement thatStarliner will undock from the ISS without a crew in "early September." The spacecraft will attempt to return to Earth autonomously, forgoing a core test objective of having a crew present and in control for the return trip.

"I know this is not the decision we had hoped for, but we stand ready to carry out the actions necessary to support NASA's decision," Boeing's Starliner chief Mark Nappi told employees in an email.

"The focus remains first and foremost on ensuring the safety of the crew and spacecraft," Nappi said.

Several senior NASA officials and Boeing representatives made the decision during a Saturday morning meeting in Houston.

NASA's space operations chief Ken Bowersox said agency officials unanimously voted for Crew Dragon to bring the astronauts home. Boeing voted for Starliner, which it said was safe.

Bill Nelson, NASA's administrator,told reporters at a news conference in Houston that he discussed the agency's decision with Boeing's new CEO, Kelly Ortberg, and was confident Boeing would continue its Starliner program.

Nelson said he was "100 per cent" certain the spacecraft would fly another crew in the future.

"He expressed to me an intention that they will continue to work the problems once Starliner is back safely," Nelson said of Ortberg.

Boeing's struggles

Boeing struggled for years to develop Starliner, a gumdrop-shaped capsule designed to compete with Crew Dragon as a second U.S. option for sending astronaut crews to and from Earth's orbit.The company is also struggling with quality issues on production of commercial planes, its most important products.

Starliner failed anuncrewed test launch to the ISS in 2019, but it mostly succeeded in a 2022 do-over attempt, which also had some thruster problems. Its June mission with its first crew was required before NASA can certify the capsule for routine flights, but now Starliner's crew certification path is uncertain.

The drawn-out mission has cost Boeing $125 million US, securities filings show. The company arranged tests and simulations on Earth to gather data that it has used to try and convince NASA officials that Starliner is safe to fly the crew back home.

But results from that testing raised more difficult engineering questions and ultimately failed to quell NASA officials' concerns about Starliner's ability to make its crewed return trip the most daunting and complex part of the test mission.

Starliner's now-uncertain path to receiving a long-sought NASA certification will add to the crises faced by Ortberg, who started this month with the goal to rebuild the planemaker's reputation after a door panel dramatically blew off a 737 MAX passenger jet in midair in January.
