Emergency on the ISS. Russia's final decision on the ship Soyuz: what is known

The exact causes of the accident on the spacecraft have not been announced, and it is still not clear how the astronauts will return to Earth.

the Soyuz spacecraft, which is now docked with the ISS, will only be in January next year, writes Space.

According to the latest reports from officials from Roskosmos, the decision on how the three ISS astronauts will return to Earth, as well as the results of the investigation into the causes of the accident on the Soyuz spacecraft, will be announced no earlier than January 2023.

At the moment, the Russian ship Soyuz, which suffered a serious accident in the cooling system, is docked with the orbital station and it is not clear whether it will be able to bring home the two Russians and an American who flew to the station in the fall.

Focus has already written in detail about the current emergency situation on the Soyuz spacecraft, which is the main vehicle of the Russian Federation for the delivery of astronauts to the ISS.

Short chronology of events:

  • December 15, a serious coolant leak occurred on the spacecraft from -for damage to the cooling system;
  • Experts called the possible cause of the accident either a hit by a small meteorite, or a defect in the ship itself;
  • A hole was found on the outside of the ship, which just confirms the theory of a meteorite hit;
  • In NASA and Roskosmos began their investigations into the incident, but the Russian side is still more engaged in searching for the reasons, since the ship belongs to the Russian Federation;
  • The question immediately arose of how the three astronauts would return to Earth and the option of sending another spaceship.

Now officials from Roskosmos have said that the “final decision” on whether to allow the damaged Soyuz spacecraft to carry astronauts to Earth will be made in January.

According to the Russian space agency, the final results are now pending investigation of the causes of the incident by a special expert group. Based on these results, which should also show the technical condition of the spacecraft, a decision will be made on changes to the flight program.

At the moment, it is known that there is a tiny hole in the outer part of the ship, and Roscosmos insists that it appeared as a result of a micrometeorite hit. But NASA can neither confirm nor deny this statement, because such micrometeorites, smaller than a millimeter in size, cannot be tracked.

With Russia unable to launch a backup spacecraft until February, this could mean the three ISS crew members don't have “lifeboats” in case of an emergency.

Potentially, these astronauts could return on the Crew Dragon spacecraft. unless something extraordinary happens and the rest of the ISS crew members do not need this ship to return. But the problem is that the spacesuits needed to fly on this ship, which is also docked to the ISS, differ from those that the astronauts who flew on the Soyuz have. That is, they simply will not be able to be inside the ship.

The emergency Soyuz was supposed to deliver astronauts to Earth in March and Roscosmos announced that they might still send a backup ship into orbit in February to pick up part of the station's crew. But this will happen only if experts confirm the unsafe flight on the Soyuz spacecraft, which suffered from the accident.

As Focus already wrote, the ISS had to perform an evasive maneuver last week to avoid a collision with the wreckage of the Russian Fregat upper stage.
