NASA mission control ordered the four astronauts of the Crew-12 mission aboard the International Space Station to enter their Crew Dragon spacecraft and don their spacesuits Friday as a precautionary measure, amid a worsening air leak in the Russian-operated Zvezda service module.

The crew — comprising two American astronauts, a French astronaut, and a Russian cosmonaut — was placed on standby for potential emergency evacuation while Roscosmos worked to address the structural breach.

Shortly thereafter, NASA spokesperson Bethany Stevens announced that Roscosmos had paused its repair efforts and that mission control had instructed the crew to stand down from safe haven procedures and return to planned operations. NASA said it looks forward to working with Roscosmos on a collaborative approach to resolving the leaks.
