Why NASA and SpaceX’s Mission to Relieve Starliner Astronauts Is Delayed Again
After an unexpected nine months in orbit, astronauts Suni Williams and Butch Wilmore are waiting for the arrival of Crew-10 before they head home. That launch is now expected for Friday

NASA and SpaceX have once again delayed a mission that means astronauts Suni Williams and Butch Wilmore will spend a little more time on the International Space Station (ISS) before heading home.
Originally sent to space on a short test flight in June, the two Americans have now been in orbit for more than nine months. Their spacecraft, Boeing’s Starliner, encountered multiple malfunctions on the way to the station and later returned to Earth without its passengers.
They’ve been waiting for the arrival of four astronauts on the Crew-10 mission, which was scheduled to lift off on a SpaceX Falcon 9 rocket from Florida’s Kennedy Space Center Wednesday night. A technical issue with a clamp arm that holds the rocket caused engineers to postpone the launch.
“This is a ground issue. Everything was fine with the rocket and the spacecraft,” NASA spokesperson Derrol Nail said during the live stream of the launch attempt on Wednesday, according to Jackie Wattles of CNN.
Inclement weather took a Thursday launch off the table, pushing the launch window to no earlier than 7:03 p.m. Eastern time on Friday.
The spacecraft will carry the Crew-10 astronauts to the station: NASA’s Nichole Ayers and Anne McClain, Japan’s Takuya Onishi and Russia’s Kirill Peskov. Once the new crew members have acclimated and completed the necessary handover with Crew-9, Williams and Wilmore will return home, no earlier than March 19.
The pair of Starliner astronauts has become the focus of public interest due to their extended stay and recent political drama surrounding their return. Despite being far from home for longer than anticipated, Williams and Wilmore have maintained a positive attitude about their circumstances.
“This is my happy place,” Williams told CNN in September. “I love being up here in space. It’s just fun. You know, every day you do something that’s work—quote, unquote—you can do it upside down. You can do it sideways, so it adds a little different perspective.”
The astronauts’ unexpected stay has also highlighted the challenges faced by Boeing in NASA’s human spaceflight program. After the issues with the Starliner capsule, NASA had no choice but to rely on SpaceX’s Crew Dragon capsule, which has been the agency’s method for transporting astronauts to and from the ISS for years.
Technically, the spacecraft that will carry Williams and Wilmore home has been docked at the space station since September—so in a way, the astronauts are not stranded and could have left at any time, writes the New York Times’ Kenneth Chang. NASA could have rushed Crew-10’s arrival to the ISS to accelerate the pair’s return, but the agency decided it was best to integrate the astronauts into the Crew-9 mission, keep the station fully staffed and stick to the intended mission schedule.
NASA moved the Crew-10 launch two weeks earlier than planned after pressure from President Donald Trump and SpaceX CEO Elon Musk, reports Reuters’ Joey Roulette. To meet the demand, NASA switched out a SpaceX capsule that was delayed and will be using a different SpaceX capsule.
The two astronauts have been helping with ongoing research and maintenance on the ISS, assisting with experiments on everything from space agriculture to physical health studies in microgravity.
Nevertheless, Williams told reporters this month that she’s looking forward to seeing her family and dogs when she gets home.
“It’s been a roller coaster for them, probably a little bit more so than for us,” Williams said of her family, per Reuters. “We’re here, we have a mission—we’re just doing what we do every day, and every day is interesting because we’re up in space and it’s a lot of fun.”
