The ISS has a major air leak, forcing NASA crew to take shelter in Dragon capsule

Business is back to normal in the orbital station, but one of two newly discovered leaks is still unrepaired

Operations on the International Space Station may have returned to normal on Friday, but concerns over a persistent air leak in the Russian segment of the station remain unresolved.NASA spokesperson Bethany Stevens confirmed on Friday that NASA had instructed crew members sheltering in a docked Dragon spacecraft to resume normal operations aboard the International Space Station after Roscosmos paused repair work in the Zvezda service module's transfer tunnel, known as PrK. Reuters reported that concerns over air leaks in the Russian module prompted NASA to order astronaut Chris Williams and the four-member SpaceX Crew-12 team into the Dragon spacecraft as part of a precautionary safe-haven procedure on Friday. The crew entered the spacecraft wearing spacesuits, per Reuters. Stevens did not specify exactly when the crew was instructed to shelter in place.
