A meeting was held today at TsNIIMash (part of the state corporation Roscosmos) at which they discussed the situation with the damaged ship docked at the International Space Station.

According to Roskosmos, the conclusions of two working groups formed to find out the reasons for the emergency situation, analyze the technical state of the ship and develop recommendations for future actions were heard. It is already obvious: the cause of what happened is external mechanical damage.

Previously, it was suggested that the heat sink of the thermal control system was damaged due to the impact of a micrometeoroid or space debris. According to the general director of Roskosmos, Yuri Borisov, a preliminary inspection showed that there is a small hole there. “About 0.8mm, which caused depressurization,” Borisov told Izvestia.

Let’s remember: on December 15, 2022, in preparation for the planned Russian spacewalk, a pressure drop was recorded in the external thermal control system of the Soyuz MS-22 manned spacecraft, which in September delivered to Roscosmos cosmonauts Sergey Prokopiev and Dmitry Petelin to the ISS, as well as NASA astronaut Frank Rubio.

A visual inspection of the ship from the station confirmed a refrigerant leak, so the departure was cancelled.

In January 2023, on the basis of the conclusions of the working groups, the commission will make organizational decisions on the further actions of ground specialists and the crew of the Russian segment of the ISS, as well as on a possible change in the program station flight.
