Following the SpaceX Dragon grapple and dock only a few days ago, there's a new update regarding the International Space Station orbit: the National Aeronautics and Space Administration (widely known as NASA) has evacuated its astronauts in an emergency move, following a gas leak.

Due to an unexpected breach in the American side of the International Space Station orbit, it has been decided that for the time being the crew from the United States will be spending time in another side of the station, after it was discovered that there was a leak.

According to The Independent, reports have surfaced that the crew from the International Space Station orbit has been evacuated from the US part of ISS due to the fact that an alarm went off that usually indicates a leak in ammoniac gas, so before anything got too serious they were moved to another side of the habitable satellite.

According to The Daily Mail, there are basically two options for the alarm to go off in the International Space Station orbit: the first is the actual presence of the toxic gas in the air, and the second would be that the sensor might be faulty; of course, checking unsafely was not worth the risk, so it was preventively considered to make the astronauts leave the premises. Nobody was ever in danger and the crew is healthy.

Express reports that, if the gas leak was indeed happening, it would have come from one of the ISS air conditioners, or "cooling systems" as the American space agency has stated.

"The U.S. section of the ISS has been isolated, the crew are safe and in the Russian section," stated Maxim Matyushin, the man in charge of of Russia's Mission Control Centre working for the International Space Station orbit. "The concentration of impurities in the atmosphere in the Russian section of the ISS is within permissible levels."
