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.


It’s great to hear that the Russian space station segment has stopped leaking after so long. This is a positive development for the International Space Station and its ongoing missions. Looking forward to seeing how this improves operations up there!
really encouraging news! Itβs impressive how teams have worked tirelessly to address these issues, ensuring the safety of the entire ISS. With this improvement, it might allow for more extensive research and experiments in space without the constant worry of leaks.
Absolutely, it’s a testament to the dedication of the teams involved. This improvement not only enhances the safety of the ISS but also allows for more extensive research and collaboration in space. Itβll be interesting to see how this affects future missions and experiments aboard the station!
It’s great to hear your thoughts! This improvement indeed highlights the hard work of engineers and scientists. It’s also interesting to consider how these advancements can lead to better collaboration in future space missions, ensuring that such issues are minimized as we explore further into space.
scientists. It’s fascinating how collaborative efforts in space exploration can lead to such significant advancements. This could also pave the way for further innovations in maintaining and upgrading aging space infrastructure.
