The International Space Station (ISS) has an ammonia leak in the US segment. In “Roskosmos” it was called insignificant, the state corporation claims that it does not affect security.
An insignificant ammonia leak in the US segment of the ISS does not affect the safety of the station and the crew and does not in any way affect the Russian segment of the ISS.
An agency source in the rocket and space industry said that a small ammonia leak was found outside the US segment of the ISS – its rate is about 700 grams per year. According to him, the leak was localized using a special American device. In 2017, a similar problem was found and fixed elsewhere outside the American segment, the agency’s source added.
Liquid ammonia outside the ISS is used to remove heat from the station modules into outer space. This chemical is classified as moderately toxic, but in high concentration it can be dangerous to human health.
The interlocutor of RIA Novosti claims that there was a similar leak in the American segment in 2017, it was eliminated during a spacewalk.
