Named the new version of the accident “Progress» – Lenta.ru

A source in the space industry announced a new version of the accident transport spacecraft “Progress M-27M”. According to him, the release of gas after opening the oxidizer and fuel tanks of the third stage was the result of the explosion of the engine. It is reported by “Interfax».

«That blast scattered in different directions from the target orbit THC (transport cargo ship – note.” Heathcliff! ») and the third step (in 40 kilometers and 20 kilometers above the lower, respectively), while creating several dozen fragments of the third stage. Only he could give the spin THC, which he got, “- said the source.

The agency’s interlocutor said that the Mission Control Center (MCC) after the ship turned into an unplanned orbit, tried using the motor mooring stop its rotation around its own axis, but this did not have a truck fuel.

The death of “Progress»

The damage from the loss of the ship is estimated at five billion rubles. Most likely, he will be recognized as debris

The source added that the perspective is also a version according to which there have been failures in the control systems. “We can not exclude that the team went to the Department of TGC earlier than necessary, even when the engine is running the third stage, which immediately caught up with the ship and hitting it,” – he said.

The State Commission meeting which took place May 12, 2015 under the chairmanship of the deputy head of Russian Federal Space Agency Alexander Ivanov, presented the preliminary findings on the situation of “progress.” Experts said that in the second flight was 526.716 unintended separation of the rocket and the truck, causing the ship was in orbit with an apogee of 40 km above the third step – in an orbit with an apogee of 20 km below the calculated trajectory launch.

Members of the State Commission came to the preliminary conclusion that an unintended separation consisted of two consecutive events associated with depressurization (opening after turning off the main engine of the third stage of the rocket) first oxidizer tank, and then the fuel tank. It is expected that the final results of the investigation will be released May 22, 2015.

Start spacecraft “Progress M-27M” was produced on April 28 with the help of a rocket “Soyuz-2.1a.” The truck was on the short-lived orbit and began to uncontrolled motion. The ship has ceased to exist on May 8 at 05:04 Moscow time, burned over the Pacific Ocean.

The cost of start-up “progress” made 2.6 billion rubles, but the insurance payments completely cover them. Problems with the truck will not affect the livelihood of the crew of the International Space Station (ISS), but have led to the transfer of the start of a new expedition to the ISS.
