NASA and Russia Clash Over Persistent ISS Leak and Safety Concerns

NASA has warned of a potential "catastrophic failure" due to a persistent air leak in the Russian-controlled section of the International Space Station, which has worsened over five years. The leak, located in a tunnel connecting the Zvezda module to a docking port, is causing safety concerns and disagreements between NASA and Roscosmos over its risks and causes. While NASA suggests mechanical stress and environmental exposure as factors, Russia attributes it to micro-vibrations. Precautionary measures are being taken, but the two agencies remain at odds over the severity and solutions.
