Agency source in the rocket and space industrytold that outside the American segment of the ISS found a small leak of ammonia - 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 is used outside the ISSfor the removal of heat from the station modules into outer space. This chemical is classified as moderately toxic, but in high concentrations it can be dangerous to human health.
RIA Novosti's interlocutor claims that there was a similar leak in the American segment in 2017, and it was fixed during a spacewalk.
