Seven-Year Zvezda Air Leak Elevates ISS Safety Risk

A hairline crack in the Zvezda module's PrK tunnel has vented breathable air into space since 2019, at times roughly 1.7 kilograms per day. NASA safety auditors have designated the PrK leak as the International Space Station's top open risk because a rapid failure could require a crew evacuation. Repairs and patches slowed the loss but did not stop it; the current workaround is to keep the hatch closed when not docking, containing the leak to the tunnel. NASA and Roscosmos remain at odds over cause and fixes, with options including permanently sealing the hatch or abandoning the aft docking port. The issue underscores aging ISS hulls and factors into the deorbit plan slated for 2030.

Seal the Door? Russia Considers Securing Zvezda to Contain ISS Leaks

With persistent leaks traced to the PrK in the Zvezda module, Russia reportedly plans to seal the hatch and abandon repairs to avoid a confrontation with NASA. While this would sacrifice a docking port and complicate reboosts, it would keep the aging ISS functional for its remaining years and reflect a pragmatic compromise between the space agencies.

Persistent ISS leaks test the US-Russia space partnership

NASA briefly ordered astronauts to prepare for an emergency departure after Roscosmos flagged ongoing leaks in the Zvezda module; crews did not evacuate as inspections continued and a permanent fix was postponed. The leaks are believed to stem from microscopic cracks; officials say there’s no crew threat, but the episode underscores the fraught US-Russia partnership on the ISS, which is slated to deorbit in 2031.
