On December 15, there was a depressurization of the external contour of the radiator of the thermal control system of the Soyuz MS-22 spacecraft. The version of technical damage to the radiator during manufacture is not confirmed. It has been experimentally proven that damage to the radiator pipeline occurred as a result of a meteoroid impact. The hole diameter is less than 1 mm.
