The results of the investigation of the accident "Union MS-10"
On Thursday, a press conference of the emergency commission for journalists was held, at which they named the cause of the accident "Union MS-10". Rumors about the valve that did not open turned out to be true, but it did not open due to the fact that the sensor was damaged when the rocket was assembled, which normally forms a command for this discovery. 3r3196.

There is no independent telemetry system on the side unit, and the mechanical sensor does not write logs, so the investigation commission had to analyze the hypotheses that the sensor was bent when the top of the step was steaming the central unit or it was damaged when the step fell to the ground. 3r3196.

Thus, the accident follows the scenario of thirty-two years old,
3r3138. [i] 03/26/1986 - Soyuz-U - Baikonur - Emergency separation of the side block G of the first step from the central block A of the second step of the PH due to the non-retraction of the upper part of the side block G due to the failure of the command to enter the keypad BU302-0M opening the cover B4300-845M of the jet nozzle oxidizer tank due to non-output of the B4411-0A contact probe stem as a result of its jamming in the housing due to deformation of the stem during assembly of the “package” at the cosmodrome, caused by the joining of the side block G with random deviation from the requirements of technical documentation by the mutual position of the blocks at the moment of docking and inserting the spherical support into the thrust bearing 3r3158. 3r3141. 3r3196.

After the press conference, Roskosmos published a chronology of the emergency rescue system. When the side unit destroyed the central one, the rocket spun tightly (we had time to notice it in the video from the ship’s cabin), and the SAS triggered the ship to the side. 3r3196.

3r3163. Conclusion 3r3164. 3r3196.
It is curious that the assembly process of this particular emergency rocket is on the Roscosmos TV video. And it seems that the fatal mistake was made just then. 3r3196.

I am against the defamation of these people. We love the phrase “every mistake has a last name, a first name and a middle name” and begin to dream of the strictest punishments possible, but the imperfection of our world is such that the one who does nothing is not mistaken. And it is more correct, in my opinion, to improve the processes so that the inevitable errors are trapped by subsequent checks and do not cause any harm. So most importantly, what was said at the press conference about the change in assembly operations. After 32 years, the Soyuz launch vehicles may well fly, but it is precisely this mistake that should not manifest itself again. Also, the incident showed at least two very good things:

3r3192. The emergency algorithms of the control system of the descent of the Soyuz spacecraft worked correctly, despite the fact that they needed to be at least refined (and, most likely, programmed again) when the on-board computers were replaced with TMA-M unions (the first flight in 2010). Soviet astronauts on the Soyuz-18-1 in 1975 were saved by a completely different computer, the Argon-16. 3r3193.
3r3192. The search and rescue service was also at the height despite the fact that the last time they searched for a ship that had landed in a planned area was 10 years ago, when the Soyuz TMA-11 crashed into a ballistic descent when returning from orbit. 3r3193.

So in the end, despite all the troubles from the accident, she showed excellent work of equipment and people, which is doubly valuable, because this work is not very noticeable in normal flight, and it is difficult to maintain readiness for decades without accidents. 3r3204.
