Air leak on ISS led to temporary evacuation preparedness

AI 生成的图像

A known air leak in the Russian section of the International Space Station ISS prompted a precautionary measure on Friday, with four astronauts seeking shelter in a Crew Dragon capsule.

The incident occurred on Friday after new cracks were discovered in the transfer tunnel on the Zvezda service module. NASA ordered crew members to don spacesuits and head to the docked spacecraft as a preventive measure. Swedish-American astronaut Jessica Meir, aboard since February, described the situation as unexpected. She had planned a meeting with Space Minister Lotta Edlund but instead sat in the capsule awaiting possible evacuation. After about an hour, NASA announced that the situation was under control. Spokesperson Bethany Stevens stated that it was not an acute emergency but merely a result of established procedures. The Russian cosmonauts continue repair work. The crew consists of three NASA astronauts, one French ESA astronaut and three Russian cosmonauts. All returned to normal operations after the incident.
