WASHINGTON: NASA officials said on Wednesday the two astronauts delivered to the International Space Station in June by Boeing’s Starliner could return on SpaceX’s Crew Dragon in February 2025 if Starliner is still deemed unsafe to return to Earth.
The US space agency has been discussing potential plans with SpaceX to leave two seats empty on an upcoming Crew Dragon launch for NASA astronauts Butch Wilmore and Suni Williams, who became the first crew to fly Boeing’s Starliner capsule.
The astronauts’ test mission, initially expected to last about eight days on the station, has been drawn out by issues on Starliner’s propulsion system that have increasingly called into question the spacecraft’s ability to safely return them to Earth as planned.
A Boeing spokesperson said if NASA decides to change Starliner’s mission, the company “will take the actions necessary to configure Starliner for an uncrewed return.”
Thruster failures during Starliner’s initial approach to the ISS in June and several leaks of helium — used to pressurize those thrusters — have set Boeing off on a testing campaign to understand the cause and propose fixes to NASA, which has the final say. Recent results have unearthed new information, causing greater alarm about a safe return.
The latest test data have stirred disagreements and debate within NASA about whether to accept the risk of a Starliner return to Earth, or make the call to use Crew Dragon instead.
Using a SpaceX craft to return astronauts that Boeing had planned to bring back on Starliner would be a major blow to an aerospace giant that has struggled for years to compete with SpaceX and its more experienced Crew Dragon.
Starliner has been docked to the ISS for 63 of the maximum 90 days it can stay, and it is parked at the same port that Crew Dragon will have to use to deliver the upcoming astronaut crew.
Early Tuesday morning, NASA, using a SpaceX rocket and a Northrop Grumman capsule, delivered a routine shipment of food and supplies to the station, including extra clothes for Wilmore and Williams.
Starliner’s high-stakes mission is a final test required before NASA can certify the spacecraft for routine astronaut flights to and from the ISS. Crew Dragon received NASA approval for astronaut flights in 2020.
Starliner development has been set back by management issues and numerous engineering problems. It has cost Boeing $1.6 billion since 2016, including $125 million from Starliner’s current test mission, securities filings show.
CONCERNS AT NASA
A meeting this week of NASA’s Commercial Crew Program, which oversees Starliner, ended with some officials disagreeing with a plan to accept Boeing’s testing data and use Starliner to bring the astronauts home, officials said during a news conference.
“We didn’t poll in a way that led to a conclusion,” Commercial Crew Program chief Steve Stich said.
“We heard from a lot of folks that had concerns, and the decision was not clear,” Ken Bowersox, NASA’s space operations chief, added.
A Boeing executive was not at the Wednesday press conference.
While no decision has been made on using Starliner or Crew Dragon, NASA has been buying Boeing more time to do more testing and gather more data to build a better case to trust Starliner. Sometime next week is when NASA expects to decide, officials said.
The agency on Tuesday delayed by more than a month SpaceX’s upcoming Crew Dragon mission, a routine flight called Crew-9, that is expected to send three NASA astronauts and a Russian cosmonaut to the ISS.
NASA’s ISS program chief said the agency has not yet decided which astronauts they would pull off the mission for Wilmore and Williams if needed.
Boeing’s testing so far has shown that four of Starliner’s jets had failed in June because they overheated and automatically turned off, while other thrusters re-fired during tests appeared weaker than normal because of some restriction to their propellant.
Ground tests in late July at the White Sands Missile Range in New Mexico have helped reveal that the thrusters’ overheating causes a teflon seal to warp, choking propellant tubes for the thrusters and thereby weakening their thrust.
“That, I would say, upped the level of discomfort, and not having a total understanding of the physics of what’s happening,” Stich said, describing why NASA now appears more willing to discuss a Crew Dragon contingency after previously downplaying such a prospect to reporters.

Backlash as Australia kills dingoes after backpacker death
- The euthanization program has stirred debate about how to manage the local population of dingoes
- Wildlife experts said killing the animals was the wrong response and may threaten the island’s dingo population
SYDNEY: Australian authorities have sparked a backlash by killing a group of dingoes linked to the death of a young Canadian woman on an island in the country’s east.
The Queensland government said six animals were put down after 19-year-old backpacker Piper James’s body was found on January 19 at a beach on the World Heritage-listed island of K’gari.
The euthanization program has stirred debate about how to manage the local population of dingoes, a sandy-colored canine believed to have first arrived in Australia 4,000 to 5,000 years ago.
An autopsy conducted on James’ body found evidence “consistent with drowning” but also detected injuries corresponding to dingo bites.
“Pre-mortem dingo bite marks are not likely to have caused immediate death,” said a spokesperson for the Coroners Court of Queensland.
The coroner’s investigation into the cause of death was expected to take several weeks.
In response, the Queensland government said a pack of 10 dingoes involved would be euthanized after rangers had observed some “aggressive behavior.”
Six of the dingoes had already been euthanized, the state’s environment minister, Andrew Powell, told reporters Sunday.
“Obviously, the operation will continue,” he said.
The traditional owners of K’gari, the Butchulla people, said the state’s failure to consult with them before euthanizing the dingoes — or wongari in their language — was “unexpected and disappointing.”
“Once again, it feels as though economic priorities are being placed above the voices of the people and traditional owners, which is frustrating and difficult to accept,” the Butchulla Aboriginal Corporation said in a statement to Australian media this week.
‘You are food’
Wildlife experts said killing the animals was the wrong response and may threaten the island’s dingo population, estimated at just 70-200 animals.
Given their small numbers, killing a pack of 10 animals would harm the population’s genetic diversity, said Mathew Crowther, professor of quantitative conservation biology at the University of Sydney.
“There’s no moral from the dingoes’ point of view. They’re just being wild animals, doing wild things,” Crowther said.
Dingoes tend to lose their fear of people as they interact with tourists, some of whom defy advice against feeding the animals.
“That’s the worst thing you can do to a wild animal,” Crowther said.
“They just relate humans to food, and if you don’t give them food, well, you are food — that’s basically how it is.”
Dingoes are wild, predatory animals and need to be treated with respect, said Bill Bateman, associate professor in the school of molecular and life sciences at Curtin University.
The canines are more likely to attack children or people who are alone, and may be triggered when people turn their backs or run, he said.
“These are important animals, and therefore we need to change the way we deal with them, otherwise we’re just going to keep reacting to these attacks and driving the population of dingoes down,” Bateman said.
Wildlife managers, rangers, Indigenous people and tourism operators need to work together so that humans and dingoes can coexist on the island, he said.
Todd James, the father of Piper, has described on social media how his family’s hearts were “shattered” by her death.
News of the dingoes’ euthanization was “heart-wrenching,” he told Australian media, adding however that he recognized it may be necessary for safety because of the pack’s behavior.
