Steve Stich, program manager for NASA’s Commercial Crew Program, said NASA is considering sending SpaceX’s Dragon Crew-9, set to launch to the ISS in September, with only two of the four astronauts assigned to it.
The spacecraft would carry extra spacesuits for Wilmore and Williams. However, the two would remain on the ISS until February 2025, when Crew-9 is set to return to Earth. Stich said the proposed plan has not formally been approved yet.
“Our prime option is to return Butch and Suni on Starliner. However, we have done the requisite planning to make sure we have other options open,” Stich said.
Stich added that Starliner does not currently have the ability to autonomously undock from the ISS. To do that, the Starliner software would need to be updated and the Boeing flight control team would need to undergo additional training.
In a statement to ABC News, Boeing said it was confident in Starliner’s ability to bring the astronauts home.
“[Crew Flight Test] is currently a crewed mission, and we still believe in Starliner’s capability and its flight rationale,” the statement read. “If NASA decides to change the mission, we will take the actions necessary to configure Starliner for an uncrewed return.”
Starliner is part of the larger Commercial Crew Program at NASA, which was testing if Boeing’s spacecrafts could be certified to perform routine missions to and from the ISS.
Wilmore and Williams were originally scheduled to return on June 14 but have since had their return delayed multiple times.
