The collision of elements during the separation of The Soyuz rocket The first and second stages are the main cause of the recall failure that forced the two astronauts to abandon the launch and make an emergency landing, media reports said.
"There is no final version, but the main cause is understandable and is related to the collision of a secondary element being part of the first stage," said Moscan's executive director in Roscosmos, Sergei Krikalyov, quoted by the newspaper. TASS news agency on October 12th.

The Soyuz MS-10 took off from the Baikonur Cosmodrome, Kazakhstan, bound for the International Space Station (ISS) at 1140 on 11 October. Russian cosmonaut Alexey Ovchinin and American astronaut Nick Hague made an emergency landing after the malfunction of their rocket.
According to NASA, there was a "problem with the booster" and the crew returned to Earth in a ballistic descent mode, which corresponds to a clearer descent angle than normal.
"A deviation from the standard trajectory occurred and apparently the bottom of the second stage disintegrated.The rocket stopped its normal flight and then the automatic system worked," Krikalyov said. .
An element of the first stage of the servomotor collided with the second stage.
"This could have been caused by the failure of the normal separation system, which should have been activated.We will analyze the causes in detail," said the head of Roscosmos.
The results of the government's investigation into the causes of the Soyuz-FG rocket's failure will be available later this month, the report said.
"The investigation commission is set to work yesterday and the results are expected after October 20. The first components discovered in the Kazakh steppe will help to find out what happened." necessary will be taken afterwards and the flights pursued, "said Krikalyov.
He added that the use of all rockets of this class would be allowed only when the causes of the failure would be clearly identified.
