ISS air-leak worsens; NASA briefly orders shelter/evacuation alert via SpaceX Dragon as Russian crew attempt Russian-segment rep
NASA briefly put ISS astronauts on a shelter and possible evacuation alert June 5 after an air leak worsened in the Russian segment. Astronauts took shelter aboard the attached SpaceX Dragon capsule while cosmonauts worked to fix the leak, before officials later determined no urgent action was needed after about 1.5 hours.
