The ISS is aging. Zvezda and the PrK launched in July 2000 and will mark a quarter-century in orbit next year. NASA wants to keep the space station operating until at least 2030, while Roscosmos, Russia's space agency, has committed only through 2028.

For the past five years, air has been escaping through a Russian section of the International Space Station (ISS) at an increasing rate. NASA and its Russian counterpart, Roscosmos, are still in disagreement over the root cause of the leak, as well as the severity of the consequences.

Crew-8 commander Matthew Dominick says NASA is carefully making decisions for astronaut safety while the ISS deals with a leak, and spacesuit issues, related to aging hardware.

Officials with NASA are at odds with their counterparts at the Russian space agency Roscosmos over the severity of a leak aboard the International Space Station.

The station has been leaking air for five years, and NASA is concerned that this might indicate a potential failure in the structural integrity of the International Space Station.

Nasa fear for 'the possibility of a catastrophic failure' after a leak was discovered in the tunnel that connects a docking port of the ISS to the Russian Zvezda module

NASA, the US space agency, is worried an air leak at the International Space Station could lead to a catastrophic failure. Spacenews.com says NASA and its Russian equivalent Roscosmos disagree over the cause of the leak in the Russian part of the space station,

NASA and Russia's Roscosmos cannot agree on how dangerous the leaks in the Zvezda module may be to the station. While Russia believes the risk is low, NASA is reportedly concerned the leaks could lead to a catastrophic structural failure.
