A possible cause of a recent coolant leak on a spacecraft docked to the ISS has become known.
As already mentioned by FocusOn December 15, the Russian Soyuz MS-22 spacecraft docked to the ISS leaked coolant from the external cooling system. A possible cause of the accident is the impact of a micrometeorite. At the same time, information appeared that the temperature on the spacecraft had risen to 50 degrees Celsius as a result of the accident.
Due to the incident on the Soyuz spacecraft, Russian dispatchers on Earth canceled the spacewalk of two astronauts from the Russian Federation – Sergei Prokopiev and Dmitry Petelin, writes ScienceAlert. According to the results of a preliminary analysis by NASA and Roscosmos specialists, this accident does not pose any threat to either the orbital station or the crew.

The representative of the Russian space agency Sergey Krikalev said that the cause of the accident on the spacecraft could be a micrometeorite hit. It was this damage to the ship's cooling system that caused the leak. According to Krikalev, this could lead to an increase in temperature on the Soyuz spacecraft, although no other problems were found. NASA also said that the astronauts on the ISS are working normally and this also applies to the station itself.
Later, information appeared that the temperature on the Soyuz spacecraft had risen to 50 degrees Celsius. This was reported to RIA Novosti by an unnamed source in Roskosmos, writes Meduza. The reason for such a high temperature is precisely the accident preceding this event. And now Russian experts are busy looking for ways to reduce it. At the same time, the source said that due to damage to the Soyuz spacecraft, its instruments may stop working.
According to former Russian cosmonaut Mikhail Kornienko, the spacecraft that delivered Prokopiev and Petelin, as well as American Frank Rubio to the ISS in September, may have to undock from the station. And in order for them to return to Earth in March 2023, another ship will have to be used. But this, according to Kornienko, will happen for the first time. According to ScienceAlert, NASA is also considering this option if there are really serious problems with the Russian spacecraft.
At the same time, official confirmation from Roskosmos regarding the temperature increase on board the Soyuz “, was not, writes Meduza. The space agency said that now the temperature on the ship is 30 degrees and this is a slight deviation from the norm, which will not affect the operation of the instruments of the spacecraft.
As Focus already wrote, now modules of the new space station are being tested, which should replace the ISS in a few years. NASA's main contractor for the creation of this orbital station is Jeff Bezos' company Blue Origin. Just the specialists of her partner in the construction of the station from the company Sierra Space conducted a test, during which they blew up the residential segment of the new station.
