Astronauts on the International Space Station (ISS) have been ordered to enter evacuation mode due to newly discovered cracks and leaks in the Russian segment's transfer tunnel. NASA press secretary Bethany Stevens confirmed that all four SpaceX Crew-12 members and NASA astronaut Chris Williams are to shelter in their Dragon spacecraft during an extensive repair operation planned for June 5. While the specifics of the repairs remain undisclosed, the situation reflects ongoing challenges with leaks in the Russian segment that have been problematic since at least September 2019. In previous efforts, crew members have employed various methods, including using a tea bag to locate leaks. NASA's inspector general has flagged these ongoing issues as a top safety risk for the station in 2024. Despite the current situation, there is no indication that the crew is in immediate danger. The ISS, which has been continuously occupied by humans for decades, is set to be retired in roughly four years, underscoring the urgent need for repairs as its age becomes increasingly apparent.
