Unresolved Air Leak on ISS Sparks Concerns of Catastrophic Failure

TL;DR Summary
The International Space Station (ISS) is experiencing significant air leaks, losing over 3 pounds of air per day, which has heightened tensions between NASA and Roscosmos. The leaks, originating from the PrK transfer tunnel between the Zvezda module and a Russian docking port, have been ongoing since 2019 and worsened this year. While Roscosmos attributes the leaks to micro-vibrations, NASA suspects more severe mechanical stresses. The disagreement extends to the potential risks, with NASA expressing concerns about structural integrity and possible catastrophic failure, while Roscosmos maintains that operations remain safe.
