NEW YORK (AP) — In a rare move, NASA is cutting a mission aboard the International Space Station short after an astronaut had a medical issue. The space agency said Thursday the U.S.-Japanese-Russian crew of four will return to Earth in the coming days, earlier than planned.

The early departure of Crew-11, leaving Williams as the only US astronaut aboard, also means NASA will be unable to perform spacewalks. This will mean a “slightly elevated risk” in NASA’s ability to respond to a major hardware failure that might require a spacewalk to fix, said Amit Kshatriya, the agency’s associate administrator.
