Boeing’s Starliner will be returning unmanned from the International Space Station, leaving the two astronauts it delivered into orbit at ISS until February.
NASA announced it would turn to Boeing-rival SpaceX to bring Butch Wilmore and Suni Williams home, extending their planned 8-day mission to about 8 months.
The decision to return Wilmore and Williams on a different craft was made out of concern for their safety, due to issues with Starliner’s propulsion system.
