Why the Russian Segment of the Space Station Is Facing a Persistent Air Leak: What You Need to Know

A stubborn air leak is still troubling the International Space Station (ISS). Despite efforts to seal it, recent observations show it’s not completely fixed.

Roscosmos officials shared updates during a press conference, stating that while recent repairs have slowed air loss, the leak continues. Sergey Krikalyov, the executive director of manned space programs at Roscosmos, mentioned, “We thought we sealed the last crack, but ongoing observations say otherwise.”

The leak first surfaced in September 2019. It was traced to a vestibule connecting a docking port to the Russian Zvezda module, which was launched in July 2000. Over the past six years, the air loss rate doubled—from one pound per day to over two. This spike prompted NASA to classify it as a high-risk issue. Earlier, both NASA and Roscosmos struggled to identify the leak’s cause or how to fix it.

In June, there was a glimmer of hope. NASA pushed back the Axiom 4 mission launch to the ISS due to a new pressure signal detected in the Zvezda module. The agency suggested this signal might indicate that repairs were effective and the leaks could be contained.

This leak is proving to be quite resilient. Krikalyov emphasized the importance of preventing such issues in future space stations. If the leak persists, agencies may consider permanently closing the hatch to the Russian module. While this wouldn’t affect daily operations, it would remove one docking option for supply ships.

Interestingly, as space agencies tackle the leak, social media is buzzing with public interest. Many space enthusiasts are sharing concerns and updates, creating a community vigil around the ISS. According to a recent survey, around 67% of Americans are now more interested in space issues, thanks to increased media coverage of the ISS and other space missions.

As the situation develops, keeping an eye on this leak could inform future designs in space travel. Monitoring how these repairs are handled may influence standards in spacecraft construction and maintenance, ensuring that future missions are safer and more reliable.
