The International Space Station (ISS) is grappling with a significant air leak originating from the transfer tunnel of the Russian service module. Engineers are working to address this issue, which has been ongoing since 2019, and results in a daily loss of approximately one pound of air. NASA has publicly downplayed the severity of the situation, but internal assessments reveal a more alarming perspective, categorizing the leak as a potential 'catastrophic failure.' NASA spokesperson Josh Finch confirmed that the module is currently maintained at lower pressure and can be repressurized as needed, ensuring that operations are not currently impacted. However, the leak has been classified as a '5' on NASA's risk matrix, indicating both high likelihood and serious consequences. Phil McAlister, a former NASA director, has suggested that this incident underscores the need for transitioning to commercial platforms by 2030, emphasizing the importance of modernizing space operations. Emergency evacuation procedures remain in place as a precaution.
