Russian Aerospace Group: Soyuz spacecraft leakage or caused by micrometeorites, does not affect the operation of the International Space Station

CTOnews.com, December 16, according to the Russian satellite news agency, Sergei Krikalev, executive director of the Russian Aerospace Group's manned space program, said yesterday that the leakage of the Soyuz MS-22 spacecraft docked at the International Space Station may be caused by a micrometeorite hitting the radiator, and the impact is limited to possible changes in the temperature of the instrument equipment cabin.

▲ map source NASA Krikalev pointed out that experts are currently analyzing the possible impact on instrument equipment cabins and spacecraft to check the heat balance. Measures will be taken on the next flight plan based on the results of the analysis. In addition, there are no other changes in the telemetry parameters of the Soyuz spacecraft and the International Space Station, and there is no danger to the astronauts.

CTOnews.com learned that the Soyuz MS-22 spacecraft was launched from the Baikonur Space launch site in Kazakhstan on September 21, sending American astronauts Frank Rubio and Russian astronauts Sergey Prokopyev and Dmitri Petelin into space.
