Astronauts on ISS told to shelter as repairs under way to fix air leaks

The five astronauts aboard the International Space Station were instructed to shelter in their spacecraft while Russian cosmonauts repaired air leaks in the station's Russian segment, specifically in the Zvezda service module's transfer tunnel. One of two identified leaks has been repaired, and authorities confirmed the crew and station systems are not in danger. Repair work was temporarily paused to assess measurements and data before astronauts were allowed to return to the station.
