The two astronauts who traveled to the International Space Station on Boeing's Starliner spacecraft could be stuck in space until next year.
On Wednesday, NASA announced a further delay in Butch Wilmore and Suni Williams' return home from the ISS.
Williams is from Massachusetts.
The astronauts were originally scheduled to return after eight days when they first went up in the Starliner in June.
Issues with helium leaks and thruster failures have forced the astronauts to remain aboard the ISS for more than 60 days.
NASA said if tests show a return flight on Starliner to be too risky, then the astronauts could be forced to wait and come back on Boeing rival SpaceX's CrewDragon in February.
