Astronauts told to return to ISS after sheltering over air leak repairs

The currently available information is limited to the title: "Astronauts told to return to ISS after sheltering over air leak repairs." From the title we can tell this is a breaking news item related to a safety incident on the International Space Station (ISS), with the core scenario being that astronauts temporarily took shelter or stayed in a safer location during air leak repairs, and were later told they could return to the ISS. The title does not specify which module of the ISS the air leak occurred in, whether the leak has been fully repaired, which space agency or mission team handled the repairs, how long the astronauts sheltered, whether emergency procedures were activated, or whether it affected the station's daily operations or return plans. Therefore, this should not be read as a known major disaster or mission failure; it can only be conservatively viewed as an on-the-spot update on the safety and repair status of the space station. For AI-circle readers, this is not news about an AI model, tool, research paper, or industry policy, but rather an event-type news item that Hacker News may have included for its relevance to technology, aerospace, and engineering safety. To further judge its importance would require additional detail from the original source — for example, whether the leak involved life-support systems, whether NASA or Roscosmos issued an official statement, whether the ISS entered a special safety mode, and whether there were subsequent mission delays or equipment inspections. Based on only the title, the summary must avoid speculating about the specific cause, attribution of responsibility, or risk level.
