A small section of the International Space Station that has experienced persistent leaks for years appears to have stopped venting atmosphere into space.
The leaks were caused by microscopic structural cracks inside the small PrK module on the Russian segment of the space station, which lies between a Progress spacecraft airlock and the Zvezda module. The problem has been a long-running worry for Russian and US operators of the station, especially after the rate of leakage doubled in 2024. This prompted NASA officials to label the leak as a "high likelihood" and "high consequence" risk.
However, recently two sources indicated that the leaks have stopped. And NASA has now confirmed this.
