Astronauts aboard the International Space Station sprung to action late Monday night following concerns that a persistent air leak had grown in size. It turned out to be a false alarm, but during the event, the crew managed to trace the source of the leak to a Russian service module.
NASA astronaut Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner were awakened by flight controllers late Monday and told to scour the Russian side of the International Space Station in an attempt to pinpoint the source of an air leak that appeared to be growing in size. Thankfully, the flight controllers were wrong, as they mistook a temporary temperature change aboard the ISS for a growing leak, according to NASA. The overall rate of the air leak, which was detected a year ago, is the same as it was before.
