Crew-12 Sheltered in Dragon as ISS air leaks prompted safety pause, then resumed operations

NASA ordered the ISS Crew-12 team to shelter inside the docked Crew Dragon after Russian repairs uncovered air leaks in the Zvezda module, with leaks rising to about two pounds of air per day; after about 90 minutes, NASA said the crew should end the safe‑haven status and return to planned ISS operations as Roscosmos continued repairs. The episode underscores ongoing discussions between NASA and Roscosmos about the leaks’ cause, and, despite this temporary safety drill, the ISS has not evacuated in its 27-year history. Crew-12 comprises NASA astronauts Jack Hathaway and Jessica Meir, ESA astronaut Sophie Adenot, Russian cosmonaut Andrey Fedyaev, and NASA astronaut Chris Williams.
