International Space Station astronauts took emergency shelter for two hours.

On the evening of June 5th at 9:04 pm Beijing time, the National Aeronautics and Space Administration (NASA) ordered multiple astronauts on the International Space Station to take refuge in the "Dragon" spacecraft docked to the space station. Five astronauts immediately entered the spacecraft for shelter and prepared for evacuation. Meanwhile, Russian astronauts attempted to repair a leak in the Russian module of the space station. Approximately two hours later, NASA lifted the shelter order and informed the astronauts that they could return to the space station. Currently, there are seven astronauts in the International Space Station, including three American astronauts, three Russian astronauts, and one French astronaut. According to a NASA spokesperson, the Russian "Progress" service module had been experiencing cracks and leaks for some time, and the Russian space agency had taken mitigating measures. However, with the emergence of new leaks, the Russian space agency decided to conduct more comprehensive repairs on June 5th. Out of extreme caution, NASA instructed four members of the 12th International Space Station crew rotation mission conducted by SpaceX, as well as American astronaut Chris Williams from another crew, to take shelter in the "Dragon" spacecraft while the Russian astronauts conducted the repair work. The Russian space agency confirmed that two potential leak points were found in the Russian module of the space station, and the Russian astronauts conducted repairs, ensuring the safety of the space station crew and systems was not compromised.
