NASA puts ISS astronauts on evacuation alert after worsening air leak

NASA ordered Crew-12 to shelter in their docked Crew Dragon and don spacesuits as a precaution after a worsening air leak on the Russian side of the ISS.
The leak traces to Russia’s Zvezda module, and NASA and Roscosmos have been debating causes and repairs for months.
Officials said the leak rate reportedly rose from about one pound of air per day to two pounds, prompting the precautionary move.
