Soyuz MS-10 was an aborted flight of the Russian spacecraft Soyuz to the International Space Station . As part of the ISS program, the flight is designated ISS AF-56S. It was to be the 56th visit by a Soyuz spacecraft to the ISS and the 162nd flight in the Soyuz program. However, the flight had to be canceled after two minutes due to a problem with the step separation . The spaceship with two spacemen was able to make a successful emergency landing.

Planned return crew

  • Alexei Nikolajewitsch Ovchinin, Commander (Russia / Roscosmos)
  • Tyler N. Hague, Flight Engineer (USA / NASA)
  • a spaceman from the United Arab Emirates . The outward flight was planned with Soyuz MS-12 , due to the lack of a return flight, the flight of this cosmonaut is not carried out.

Mission description

The mission was to bring two crew members from ISS expeditions 57 and 58 to the International Space Station. Originally, Nikolai Tichonow was also supposed to fly to the ISS with Soyuz MS-10. However, as with Soyuz MS-04, he was taken off the mission by Roscosmos. This time, the reason was a further delay in the planned start of the Russian research module Naúka . On the return flight, the vacant space was to be taken by a spaceman from the United Arab Emirates who was planning a short stay on the ISS.

Abortion of the mission and emergency landing

Almost two minutes after take-off, the separation of the first stage of the Soyuz launcher, consisting of four boosters , was initiated as planned. The boosters are first released at the lower end and rotate outwards. Then a valve opens in the upper area of ​​the booster, through which the remaining oxygen flows out of their tanks. The recoil causes them to spin away from the missile.

When assembling the MS-10 rocket, the sensor on one of the boosters that triggers the opening of the valve was bent. The booster was not pushed away, but collided with the second stage and damaged its tank. As a result, the attitude control failed and the rocket began to rotate. This automatically activated the rescue system at a height of around 50 kilometers - as provided in such cases - which separates the spaceship from the rocket and maneuvers it out of the danger zone. At this point in time, the rescue rocket, which had been dropped as planned a few seconds earlier, was no longer used at the tip, but special engines fired on the payload fairing of Soyuz MS-10. The emergency landing was then initiated, with the landing module returning to earth at a steeper angle than when landing from orbit. The landing site was 32 kilometers southeast of the city of Sheqasghan in the Kazakh steppe. Search and rescue teams made their way to the spaceship's expected arrival point immediately after the incident. The crew was unharmed and was then brought back to Baikonur . A state commission investigated the incident and issued a preliminary report. The final report was announced for October 30, 2018, and a press conference was held on November 1.
