Commission Roskosmos State Corporation to investigate the causes of the hole in the spacecraft "Union MS-09" held on Monday the first meeting. As Nikolay Sevastyanov, chairman of the commission, told journalists, the plan of work was outlined: the crew is being trained and sent to the International Space Station (ISS) on November 15, and it is he who personally checks the presence of a sealant inside the docked ship's hull. This will allow you to determine exactly where you worked with a drill - in space or on earth. The state corporation Kommersant also said that the internal commission of the RSC Energia found the true reasons and the perpetrators of the appearance of the hole failed.
The fact that RSC Energia hosted the first meeting of the Roskosmos commission to investigate the reasons for the opening of the Soyuz MS-09 spacecraft became known on Tuesday. The commission, which began its work last week, was headed by the acting President. The first deputy head of the state corporation Nikolai Sevastyanov. He said that the experts outlined a plan for the upcoming investigation. According to him, Roskosmos will send two specialists to the ISS. They will go into open space and cut out some of the anti-meteorite protection from the outside of the docked Soyuz spacecraft to investigate the hole that led to air leakage from the station. Crew members on the ISS can not do this now, since special operations are required for such an operation. Two specialists have already started training, Nikolai Sevastyanov specified.
The cosmonauts' exit into outer space is scheduled for November 15. "They have a task to approach the ship and work with it outside. Usually the output lasts about six hours, this task will roughly take about two hours, that is, a third of the usual output, "Mr. Sevastyanov explained. Cutting a piece of protection with a special scissors, the astronauts will find out if there are any traces of drilling on the outside of the hole. It is a question of burrs on an aluminum sheet and glue traces, which were originally covered with a hole if it appeared on the ground. The design of the module is such that the main body is covered with anti-meteorite protection sheets. Between them and the main body there is a small gap, which only the Earth could reach with a sealant. Thus, as suggested by Roskosmos commission, the presence of glue residues may indicate that the hole did not appear in space, but suspect that the probability of this is extremely small.
A hole in the docking of the docked Soyuz was discovered on August 30, when the sensors on the ISS showed a slight decrease in air pressure. In the evening of the same day, the crack was treated with a sealant, at present it is completely enclosed. First on earth, it was suggested that the cause of the hole was a micrometeorite, but soon it became clear that it was a hole from a drill.
On September 10, the head of the RSC Energia Sergey Romanov presented a report on the results of the investigation of the company's internal commission (this commission has already completed its work, the second commission was created after) to the director general of the state corporation Dmitry Rogozin. As Kommersant learned today, the first commission was unable to establish the true causes of the damage and the perpetrators of its appearance. The specialists did not find evidence that the hole appeared at the plant. "The commission has not identified any systemic problems and has completed its work," explained Mr. Sevastyanov.
As previously reported to "Kommersant" (see the September 12 issue), one of the versions of the causes of the depressurization of the spacecraft was the deliberate drilling of the hole by American astronauts. While the official confirmation in "Roskosmos" this information was not received. In addition, the American astronaut, the commander of the ISS crew Andrew Feistel rejected this option: "I can say unequivocally that the crew is not involved in this." Mr. Feistel called attempts to accuse astronauts a waste of time.
The commission under the leadership of Nikolai Sevastyanov will meet every two weeks and will finish its work by the end of November.
