Serious ISS air leak forces NASA astronauts to temporarily take shelter in Dragon capsule
NASA says life on the ISS is back to normal for now, but a persistent air leak in Russia’s Zvezda module keeps watchers on edge. After pausing repairs in the transfer tunnel, Roscosmos and NASA paused their assessments, then told the crew in the Dragon to end safe-haven precautions and resume standard ops. Reported leaks have grown from about a pound to two pounds of air per day, with the latest inspections pointing to the longest cracks seen yet. One leak was sealed with Germetall-1 sealant; a second remains to be hermetically sealed. NASA and Roscosmos are reviewing measurements to pin down the root cause and whether the issue could threaten station viability or retirement plans
