Space Station Leak Prompts Brief Astronaut Safety Protocol

Astronauts aboard the International Space Station (ISS) briefly entered a safety procedure on Friday after Russian space agency Roscosmos paused repair work on a leak within a module. The temporary suspension allowed for further evaluation of collected data regarding the issue.

The leak is located in the transfer tunnel of the Russian Zvezda service module, known as PrK. NASA spokesperson Bethany Stevens stated that both NASA and Roscosmos are working together to pinpoint the root cause of the cracks and leaks that have been affecting the tunnel for some time. Roscosmos has been managing the situation with operational mitigation steps and periodic partial repairs.

Initially, Roscosmos had planned more extensive repairs on Friday following reports of a new leak. As a precaution, NASA instructed four members of the SpaceX Crew-12 mission and astronaut Chris Williams to shelter in the Dragon spacecraft during the repair process. However, once Roscosmos halted the operations, NASA permitted the crew to end the enhanced safety protocol and return to their scheduled activities.

The affected astronauts included Jessica Meir and Jack Hathaway from NASA, Sophie Adenot from the European Space Agency (ESA), Russian cosmonaut Andrey Fedyaev, and Chris Williams, who arrived on the ISS via a Soyuz spacecraft. Stevens confirmed that NASA will continue to coordinate with Roscosmos on their joint efforts to address the leak in the Russian segment of the ISS.
