NASA and Roscosmos have been monitoring an air leak inside Russia's Zvezda service module on the International Space Station since 2019. The leak rate increased during cargo operations, prompting a more extensive inspection and repair effort.

The International Space Station (ISS) has been experiencing a small air leak issue since 2019. The affected area is called the PrK transfer tunnel inside Russia's Zvezda service module.

NASA and Roscosmos have been working together to understand the root cause of the leak and reduce its impact. They've used different types of sealants, including temporary and permanent ones, as part of their efforts.

Recently, the leak rate increased during cargo operations involving the Progress 95 spacecraft. This prompted engineers to identify new suspected leak areas inside the PrK transfer tunnel.

As a precaution, NASA directed the astronauts on board to take a heightened safety posture known as a safe haven. They sheltered inside the SpaceX Dragon spacecraft while the repair procedure was being evaluated.

Roscosmos decided not to proceed with the structural repair work and instead chose to gather more measurements and review additional data. This decision was supported by NASA.

After pausing the repair effort, the astronauts ended their safe haven activities and returned to normal operations aboard the ISS. NASA will continue working with Roscosmos and other international partners to assess the situation and ensure the leak issue is resolved.
