ISS PrK Module Leak Stops After Years of High-Risk Anxiety
The persistent air leak in the ISS PrK module has finally stopped. NASA confirms the end of a years-long crisis that saw leak rates double in 2024.
The persistent air leak that's been haunting the International Space Station (ISS) for years has finally gone quiet. NASA officially confirmed that the venting from the Russian segment's PrK module has ceased, marking a significant relief for orbital operations.
Inside the ISS PrK Module Leak Crisis
The trouble started with microscopic structural cracks within the PrK module, located between the Zvezda module and a Progress spacecraft airlock. The situation turned critical in 2024 when the leakage rate suddenly doubled. This spike forced NASA officials to designate the leak as a "high likelihood" and "high consequence" risk, sparking fears over the long-term viability of the Russian segment.
Recent Stabilization and NASA Confirmation
While the leak had been a long-running worry, recent data from two sources indicated that the atmosphere is no longer escaping. NASA has since verified these reports. It’s a major win for the station's maintenance crews, though they'll likely keep a close watch on the area to ensure the cracks don't reopen under the intense thermal cycling of low Earth orbit.
