After a refrigerant leak from the thermal control system of the Soyuz MS-22 in December last year, the temperature on the ship reached 60-70 degrees Celsius. According to Interfax, this was announced by the head of the flight of the Russian segment of the International Space Station Vladimir Solovyov.
“The rise in temperature, when we calculated it, it turned out to be catastrophic, there we very quickly approached temperatures of 60-70 degrees,” he said in a video distributed by the press service of Roscosmos.
According to him, there are also devices on board the ship that are not suitable for high temperatures. “At temperatures somewhere around 40 or 50 degrees, the microcircuits are already starting to fly out,” the flight director noted.
Earlier, Roskosmos reported that after the damage, the temperature in the instrument and assembly compartment of the Soyuz MS-22 spacecraft reached plus 40 degrees, and in the residential compartment – plus 30.
The state corporation noted that these changes in the temperature regime are not critical and there is no need for emergency evacuation of astronauts.
