NASA Astronauts Seek Shelter in SpaceX Dragon Due to ISS Air Leak Repair

NASA ordered five astronauts on the International Space Station (ISS) to take shelter in a SpaceX Dragon spacecraft while Russian cosmonauts worked on a persistent air leak. According to NASA spokesperson Bethany Stevens, the decision was made "out of an abundance of caution" as the team executed repairs on the leak located in the PrK transfer tunnel, connected to Russia's Zvezda service module.

The leak, attributed to small cracks that have developed over the years, was previously managed by Russia's space agency, Roscosmos, through various repair efforts. These repairs, however, ceased to be effective recently, prompting the more intensive work initiated today. The astronauts, part of SpaceX's Crew-12 mission along with NASA astronaut Chris Williams, sheltered in the Dragon capsule “Freedom” during the operation.

Following initial repair attempts, Roscosmos decided to pause the work to reassess the situation, leading NASA to instruct the crew to return to normal operations aboard the ISS. This incident highlights the aging infrastructure of the ISS, which began construction in 1998 and has been continuously occupied since November 2000. Despite the challenges, the ISS is expected to remain operational until at least 2030, with possibilities extending to 2032.
