NASA's Crew Safety Alert Exposed a Bigger ISS Leak Problem

The ISS air leak has intensified into a major ongoing issue, prompting shelter‑in‑place actions as NASA and Roscosmos debated repair access. On Friday, June 5, five crew members moved into a SpaceX Dragon while Roscosmos pursued a plan to cut a bracket to reach a suspected crack in the PrK transfer tunnel that connects the Zvezda module. NASA warned the maneuver could raise structural risk, and Roscosmos paused to collect more data as two cosmonauts and four astronauts prepared to continue work.
