The current temperature range aboard the Soyuz MS-22 is kept between 28 and 30 degrees Celsius, staying within the standard limits. This information comes from the Roscosmos press service via its official telegraph channel.
Earlier reports suggested that daytime warming on the Soyuz MS-22 was caused by cooling-system malfunctions, with temperatures reportedly spiking to as high as 50 degrees Celsius. Roscosmos clarified that those claims did not reflect the actual situation on board.
The agency stressed that crew safety and comfort are not at risk at this time, and the ship continues to operate under approved thermal-control parameters.
Additionally, Roscosmos reported that on December 17 the crew conducted routine station cleaning. In the afternoon, Sergei Prokopiev, Dmitry Petelin, and Anna Kikina were scheduled to have a rest period through the morning of December 19, ensuring proper crew rhythm and maintenance cadence.
On December 15, Sergei Krikalev, the head of manned space programs at Roscosmos, indicated that a micrometeorite impact might have damaged the outer surface of the Soyuz MS-22 radiator assembly. He noted that such damage could influence the thermal regime of the facility and potentially alter temperatures in connected systems.
Throughout the mission timeline, mission controllers have emphasized careful monitoring of onboard environmental conditions, with corrective actions prepared should any deviations occur. The focus remains on maintaining stable thermal performance while enabling uninterrupted crew operations and scientific activities. All statements cited originate from official Roscosmos communications and subsequent corroborations from spaceflight monitoring teams.
