ISS Faces Critical Air Leak Challenge

The International Space Station (ISS) is facing a critical challenge due to an ongoing air leak in the Russian-controlled Zvezda module, initially detected in 2019 and recently escalating. NASA and Roscosmos have differing views on the severity and causes of the leak, with NASA concerned about potential catastrophic failure and structural integrity, while Roscosmos believes the situation is manageable. Earlier this year, the leak rate peaked but has been partially controlled by Russian cosmonauts' efforts to seal problematic areas. NASA attributes the leak to factors like pressure variations and material stress, whereas Russian engineers suggest micro-vibrations as a possible cause. Despite meetings and discussions, both agencies have not reached an agreement on the safety and sustainability of continued operations, and NASA is advocating for independent experts to evaluate the issue. The leak remains the most pressing issue for the ISS, threatening astronaut safety if unresolved.
