NASA said it could permanently isolate the Russian Zvezda module from the ISS due to an air leak

According to NASA ISS program director Robin Gatens, the Russian Zvezda module of the ISS station, in case of emergency, is waiting for permanent isolation if the crew fails to eliminate the air leak. “The leak is so small that it is difficult to detect with detectors and ultrasonic diagnostics,” said Gaitens.
