@reuters: A worsening air leak aboard the International Space Station ‌prompted five astronauts to take shelter and prepare for evacuation as Russia attempted to fix a crack on its portion of the orbital laboratory, NASA said. NASA reversed that order roughly two hours later and told the astronauts they could return to the station as the agency and its Russian counterparts examined the rate of leaking air. #astronauts #nasa #internationalspacestation #iss #airleak
