Overview
- NASA directed five astronauts to board the docked SpaceX Crew Dragon and suit up as a precaution on Friday after Roscosmos detected new leaks in the Russian segment of the ISS.
- Russian specialists reported two leak points in the Zvezda module's PrK transfer tunnel, sealed one quickly and then suspended invasive repair work to collect additional diagnostic data.
- Mission controllers lifted the shelter‑in‑place order after roughly two hours once Roscosmos halted the planned structural intervention and both agencies agreed to continue monitoring.
- Ground teams say the station's air loss rate recently rose from about 0.5 kilograms per day to roughly 1 kilogram per day, increasing concern but not creating an immediate threat to crew safety.
- The episode highlights chronic wear in Zvezda, a module installed in 2000, and underlines the reliance on the Dragon and Soyuz spacecraft as on‑station lifeboats while NASA and Roscosmos plan longer‑term fixes.
