According to the head of Roscosmos, Dmitry Rogozin, the accident of the carrier rocket “Soyuz-FG” that occurred on October 11, happened because of errors in its Assembly directly at the Baikonur cosmodrome. An emergency situation occurred at the 118-th second of the flight. In the accident “Soyuz-FG” was not able to put into orbit the spacecraft “Soyuz MS-10” with the new ISS crew. On Board were the Russian Alexey Ovchinin and American Nick Haig. The crew managed to evacuate to Earth in a rescue capsule. Fortunately, no one was hurt. For 35 years this is the first emergency case at start of manned spacecraft, reports TASS.
Rogozin also said that the particular artist that made a mistake when assembling the rocket, is already known. Created a Commission to investigate the incident. Criminal case about infringement of safety rules of construction works.
“It is a violation of operational plan — a mistake was made during Assembly of the rocket at the Baikonur cosmodrome, these are the conclusions of all members of the emergency Commission, they reported to Roscosmos,” — said the head of Roscosmos.
The results of the investigation of the Commission has already passed the U.S. space Agency NASA.
During the inspection it was found that the side unit was not properly attached to the rocket. During the installation is not prescribed in the regulations used tools, which allow with high accuracy to ensure the Assembly process.
“The defect is not constructive,” — said Rogozin.
Incorrect connection of the side block led to incorrect operation of the sensor separation steps. The unit is separated incorrectly and hit into the second stage of the launch vehicle, damaging the fuel tank. Because of this, the rocket began to collapse.
The Commission conducted the investigation developed recommendations for those already assembled rockets. Now every development and Assembly is carefully controlled. All stages of the production process will be recorded on photo and video. In addition, it is recommended to conduct a recertification of all employees of the Baikonur cosmodrome in charge of assembling the “Unions”.
