On October 11, the Soyuz-MS-10 planned launch with the Soyuz-FG launch vehicle took place. But he failed to go into orbit. The accident occurred at the 119th second when the side blocks of the first stage were separated from the central unit of the second stage. Then the emergency beacon worked, the ship divided into compartments and released a parachute. The crew is alive and crash landed in Kazakhstan. After the investigation, it became known what led to the accident of the carrier.

According to RIA Novosti, referring to a source familiar with the investigation, in assembling the Soyuz-FG rocket, the experts used excessive force and bent the part, holding the steps together. This was the cause of the accident.

What did the Soyuz collapse from?
“When assembling, when assembled, the assemblers assembled the steps into a“ package, ”the left ledge slightly bent, it did not immediately enter the groove – and it was driven out with force. When the step fell on him with the whole mass, the projections, in fact, stood in a strut. In order to make the stage easier to separate, a grease was applied to the hole, ”said the source.

Because of all this, the ball bearing of the side unit could not easily get out of the thrust bearing and rammed the central unit during the flight. The consequences you know.

According to the results of the investigation, a discussion took place at a meeting of the emergency commission at the Progress center. Specialists were asked about the “production culture”. In response, they said that sometimes when assembling rockets it is necessary to deviate from the technological documentation. That is, do not as written.

Public announcement of the causes of the accident will take place early next week.

With all this, the launch system of the Union is currently the only way to send people into space. SpaceX and Boeing are working on their alternatives, but they are still far from ready. The Soyuz missiles remain reliable enough to take people into space.
