NASA says a crew member aboard the International Space Station is stable after a medical situation, prompting the agency to postpone the planned Jan. 8 spacewalk.
Officials are evaluating all options, including possibly ending the Crew-11 mission early.
The walk had been scheduled for today and was intended to prepare for the installation of a new solar array.
The station currently hosts two NASA astronauts, a Japanese astronaut, and a Russian cosmonaut.
NASA emphasized that safely conducting missions is the top priority and said such situations are part of routine training and preparations. Further updates are expected within 24 hours.
