“On Friday, specialists from the Mission Control Center near Moscow, together with Russian cosmonauts aboard the International Space Station, conducted a number of tests of the systems of the Soyuz MS-22 manned spacecraft, including measuring the temperature in the spacecraft’s living space (descent module and utility compartment), where the temperature was about +30 °C,” the message says.

It is noted that this is a slight change in temperature.

On December 15, cosmonauts, after a visual inspection, confirmed a leak from the cooling system of the Soyuz MS-22 spacecraft.
