NASA has growing concerns about an ongoing air leak on a Russian section of the International Space Station (ISS) that has been going on since 2019.

According toSpaceNews, Bob Cabana, a former NASA astronaut who now chairs the ISS Advisory Committee, raised the issue during a meeting on Wednesday, Nov. 13.

“While the Russian team continues to search for and seal the leaks, it does not believe catastrophic disintegration of the PrK [module] is realistic. NASA has expressed concerns about the structural integrity of the PrK and the possibility of a catastrophic failure,” said Cabana.

“The Russians believe that continued operations are safe but they can’t prove to our satisfaction that they are, and the U.S. believes that it’s not safe but we can’t prove to the Russians’ satisfaction that that’s the case,” he continued, per the news site.

Areportfrom NASA’s Office of Inspector General published in September stated that while the leaks' root cause remains unknown, the ISS and Russia’s space agency, Roscosmos, have “narrowed their focus to internal and external welds.”

The ISS Program and Roscosmos officially met in May and June to discuss heightened concerns, elevating the leak risk to the highest level in its risk management system, per the report.

“According to NASA, Roscosmos is confident they will be able to monitor and close the hatch to the Service Module prior to the leak rate reaching an untenable level. However, NASA and Roscosmos have not reached an agreement on the point at which the leak rate is untenable,” the report further stated.
