The state Commission on investigation of the crash of a cargo spaceship “Progress MS-04″ heading to the International space station (ISS), began to work. As reported by “Interfax”, first and foremost it will decode the telemetry received before the 383-th second of the flight lost contact that will allow you to determine which systems and components failed.

According to the source Agency in the space industry, the decoding can be completed at the beginning of December, and the first conclusions are made mid-month.

According to Roscosmos, the cargo spacecraft “Progress”, launched on the eve of the Baikonur cosmodrome using rocket “Soyuz-U” was lost at an altitude of 190 km over Tuva. Most of the debris burned in the dense layers of the atmosphere. As it became known, the wreckage fell in the 60-70 kilometers West of the city Kyzyl. Information on casualties or damage were reported. While the wreckage was not found.

On the causes of the crash were not reported, experts have only a preliminary version. The state Commission investigating the accident, leaning to the assumption that maybe the crash happened because of the burnout of the engine of the third stage of the rocket, said on Friday, TASS source in the space industry. The burnout could lead enters the engine extraneous particles and poor Assembly of the engine.

In turn, the source RIA “Novosti”, said that as one of the versions of falling of the space truck may be considered negligence in the manufacture of the RD-0110 of the third stage of the carrier rocket “Soyuz-U”.

“Most likely, the outcome of the investigation, the state Commission once again will be forced to admit revealed the poor quality of Assembly of the RD-0110 and bench simulation that will be conducted after analysis of the available telemetry, it will show which component of the propulsion system was made with violations,” – said the Agency interlocutor.

If the fault of the engine builders will be proved, most likely this will be followed by some personnel decisions, the source said. In this case, all the finished engines, including those already installed on launch vehicles of “Soyuz” type, it will be necessary to remove, deliver to the company, re-test, to eliminate possible defects in the Assembly that will lead to yet another postponement of the planned launches, he said. Note that the developer of the RD-0110 is Voronezh KB Khimavtomatika.

The source stressed that until the end of the emergency to the Commission any final conclusions to do prematurely.

In Roscosmos earlier said that “the loss of the cargo ship
will affect the normal operations of the ISS and life
the space station crew”. “Progress MC-04″ was to deliver to the ISS about 2.5 tons of various cargoes, including propellant for refueling the ISS, water and air for astronauts. In the cargo hold was laboratory equipment and accessories, containers with food, clothes, medicines and personal hygiene products. The next cargo ship “Progress of MS” it is planned to send to the ISS 2 Feb.

In the past flying cargo “Progress” had twice over
failure. A similar accident with a rocket carrier “Soyuz-U”, which led to the fall of the truck “Progress M-12M”, took place on 24 August 2011. Unburned elements of the third stage and spacecraft fell in the sparsely populated mountain area of the Altai Republic. The cause of the accident was declared abnormal operation of the engine RD-0110 third stage of the rocket – a violation of the conditions of functioning of the gas generator. According to the Commission, to the state of emergency caused reduction in fuel consumption due to clogging of the path of its submission. Then, a manufacturing defect was ruled accidental.

Another cargo ship “Progress M-27M”, launched on 28 April
2015 from the Baikonur cosmodrome using rocket “Soyuz-2.1 a”,
has an arbitrary unmanaged decayed and ceased to exist
May 8. The entrance to the dense layers of the atmosphere occurred at the 160-m coil over the Central Pacific ocean. As reported in the “Roskosmos”, the reason for the failed launch of “Progress M-27M” was the damage to the ship,
the resulting non-standard separation from the third stage
booster.
