NASA and Russia Clash Over ISS Leak Severity Amid Catastrophic Concerns

NASA and Roscosmos are at odds over the severity of ongoing leaks in the Russian segment of the International Space Station, with NASA warning of potential catastrophic failure while Roscosmos downplays the risk. The leaks, attributed to factors like micro-vibrations and mechanical stresses, have been a persistent issue, leading to disagreements over their cause and impact. Despite the concerns, some NASA officials have minimized the threat, noting that sealant applications have reduced leak rates. The situation highlights the aging infrastructure of the 24-year-old space station.
