A section of the Russian-controlled International Space Station (ISS) has been leaking for several years, letting pressure and air escape. The leak has recently gotten worse, raising questions about both the crew’s safety and the orbiting laboratory’s long-term sustainability.

Leaks are affecting a key part of the International Space Station. NASA and Russia’s space agency, Roscosmos, are not seeing eye to eye about the level of risk.

The space station having a size equal to a football field must remain pressurised and filled with breathable gases at all times.

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.

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.

NASA has concerns about the structural integrity of the Russian module and the "possibility of a catastrophic failure," per ISS Advisory Committee chair Bob Cabana

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, 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,
