WASHINGTON—A worsening air leak aboard the International Space Station prompted five astronauts to take shelter and prepare for evacuation for roughly two hours on Friday as Russia attempted to fix a crack on its portion of the orbital laboratory, NASA said.
The four astronauts of NASA’s Crew-12 mission aboard the station — two Americans, a French astronaut and a Russian cosmonaut — along with another U.S. astronaut were ordered by NASA mission control at 9:04 a.m. ET (1304 GMT) on Friday to enter their SpaceX-built Crew Dragon spacecraft docked to the station, NASA spokesperson Bethany Stevens said.
