NASA audit identifies ongoing leak as top safety risk for International Space Station

A NASA audit has identified a long-standing leak in the Russian segment of the International Space Station (ISS) as the top safety risk. The leak, ongoing since 2019, has recently increased to 3.7 pounds per day, raising concerns about the aging station's operations. NASA and Roscosmos are investigating the leak, which affects the Zvezda module. While officials state it poses no immediate threat to crew safety, the ISS requires ongoing maintenance and repairs to remain operational until its planned retirement in 2030. The audit also highlighted other risks, including space debris and potential failures of commercial spacecraft. Recommendations include improving tracking practices and preparing for the ISS's eventual deorbiting, with SpaceX selected for the task.
