NASA placed five astronauts on standby for potential evacuation from the International Space Station (ISS) on Friday due to a significant air leak in the Zvezda service module. The alert was initiated at 9:04 am ET as Russian experts worked to repair a crack in the module, which had seen its air loss rate unexpectedly double from one pound to two pounds per day. The Crew-12 mission, which includes two American astronauts, a French astronaut, and a Russian cosmonaut, was instructed to move to their docked SpaceX Crew Dragon spacecraft as a precaution. After discussions between NASA and Russia’s space agency, Roscosmos, the evacuation order was lifted about two hours later. Roscosmos confirmed that one of the two identified leaks was sealed, and there was no immediate danger to the crew or the ISS systems. NASA expressed its commitment to collaborating with Roscosmos to address the leaks, emphasizing that despite regular emergency drills, there has never been a need for an evacuation in the ISS's history.
