Having studied all the materials, the members of the State Commission came to the preliminary conclusion that objectively confirmed version abnormal division, including two consecutive events associated with depressurization (opening after turning off the main engine third stage rocket) first oxidizer tank, and then – fuel tank third stage of the launch. The working group will present its findings on 22 March. As a result, the ship and the third stage of the rocket were on an unplanned orbit. Attempts to contact the cargo transport ship were unsuccessful – to stabilize the situation “progress” and reduce the rotation around its own axis was not possible.
The upgraded carrier rocket “Soyuz-2.1a” Samara Production Rocket Space Center “Progress” with cargo spacecraft “Progress M-27M” launched from Baikonur on April 28. “There has been an unintended separation of the third stage of the rocket carrier cargo ship.” The accident “Progress” will not affect the livelihood of the crew of the International Space Station. “At this point, lost virtually all telemetry data that was on board the launch vehicle and partly on board the cargo ship,” – said the first deputy head of the Federal Space Agency Alexander Ivanov. It turned out that a missile brought it to a higher orbit than planned. Experts have tried to take the “Progress” under control, but contact with the ship could not – he began the descent of uncontrolled orbit.
