‘Possibility of a catastrophic failure': Inside the space station leak problem that has NASA worried

## Russian Segment of ISS Suffers Increased Air Leak

A persistent air leak has been identified in a Russian-controlled section of the International Space Station (ISS), causing concern among astronauts and officials. Pressure is slowly escaping from this crucial part of the space laboratory, exacerbating safety concerns. Cosmonauts are working diligently to address the leak, while disputes arise between Roscosmos and NASA regarding the severity and potential impact on the ISS's structural integrity.

The leaks were first discovered in 2019 within a tunnel of the Zvezda module, a key connection point for incoming spacecraft with cargo. This year, however, the leakage has intensified, prompting the U.S. to classify it as an urgent safety threat. While NASA has flagged potential catastrophic risks, Roscosmos considers continued operations safe but lacks definitive evidence to convince their U.S. counterparts.

Efforts to agree on the severity and causes of the leaks continue as NASA advocates for an independent investigation involving experts from both agencies. Disputes have persisted despite recent discussions between the agencies. In the meantime, astronauts on board are employing safety measures, such as sealing off the leaking segment when not in use.

The leak presents a challenge, not just for the current crew's safety but also for the future of the aging ISS. As the agencies contemplate the station's eventual decommissioning, concerns about safely retiring the ISS and the necessity for an alternative space lab loom large. Commercial partners are exploring developing new space platforms, but their readiness by the time ISS operations potentially conclude remains uncertain.
