June 5 (UPI) — NASA briefly moved five of the seven crew members aboard the International Space Station to the docked SpaceX Crew Dragon “Freedom” while Russian cosmonauts planned to repair leaks in a transfer tunnel in the Russian module.

The Russian crew members decided to only perform measurements Friday, so Mission Control told the crew members it was OK to exit the safe haven configuration.

“Roscosmos has paused Friday’s structural repair efforts … as more measurements and data is assessed. Given this development, NASA has instructed the crew members inside the Dragon spacecraft to end the safe haven procedures and return to planned operations aboard the International Space Station. We look forward to working with Roscosmos on a collaborative approach to address the leaks,” NASA Spokesperson Bethany Stevens posted on X.

The cracks have created a small air leak on and off for about six years and is a safety risk.

“The Zvezda service module transfer tunnel, known as PrK, has suffered from cracks and leaks for some time, and has been mitigated by Roscosmos as much as possible to date. The cracks have always been a concern that NASA watches very closely. NASA and Roscosmos have been working to determine the root cause of the cracks, and Roscosmos manages the issue through operational mitigation measures and periodic partial-repair efforts,” Steven wrote in another post.

The NASA Crew-12 members on the ISS include: Jessica Meir, Jack Hathaway, Sophie Adenot and Andrew Fedyaev. Astronaut Chris Williams went to the Dragon spacecraft, Stevens said.

Roscosmos noticed a slow pressure drop in the tunnel last month after a Russian cargo ship arrived, CBS News reported. NASA and Roscosmos have been working on “operational mitigation measures and periodic partial-repair efforts.”
