1. According to preliminary information, the damage could have been caused by the micrometeoroid or space debris hit into the external cooler radiator located on the service module of the Soyuz MS-22 spacecraft.
2. There is currently no need for an emergency evacuation.
3. Due to the conducted tests of the ship’s systems, the temperature in the orbital and descent modules in the first days after the incident reached +30 C, and in the service module - +40 C, but in recent days, the temperature in the whole ship stabilized at about +30 C.
4. Two working groups have been formed to find the cause of the incident, analyze the technical condition of the ship and develop recommendations for further actions for ground specialists and the cosmonauts.
5. On December 16, 2022, a number of tests of the Soyuz MS-22 systems were conducted, including the thrusters tests. They have shown that there are no other malfunctions. The specialists plan to continue the tests.
6. On December 18, 2022, the outer surface of Soyuz MS-22 was examined using the cameras of the manipulator arm. The analysis of the data received on Earth allowed to detect a possible place of damage on the surface of the service module.
7. By the end of December, the working groups will make their conclusions, and a decision on the future of Soyuz MS-22 will be made. There are 2 options: to land the crew on this ship in March 2023, as planned, or send Soyuz MS-23 in an automatic mode to replace Soyuz MS-22.
That’s all. That was very informative, thank you @roscosmos. That’s what we wanted to hear - an explanation of the situation and your possible steps.
