Experts made version of the explosion in the breeding of “progress” – RBC

When fading cargo spacecraft “Progress M-27M” into orbit could cause an explosion, told Interfax a source in the space industry, close to the commission of inquiry. According to him, this is indirect evidence analysis of the orbits of debris found near the ship.

«US and Russian space monitoring tools found near the” progress “several dozens of obscure fragments. Now experts are busy with their identification and analysis of their orbits. According to one of the pre-release “cloud” fragments could be formed as a result of the explosive effect, “- he said, adding that, most likely, the explosion occurred at the time of the separation of spacecraft from the third stage.

According to the US space center in orbit near the ship, and the third stage carrier 44 fixed debris. Experts drew attention to the large scatter fragments of heights – from 170 km to 370 km at apogee, from 130 to 180 km at perigee.

According to the source, given this fact, and the fact that the ship “Progress” was found about 30-40 km above the calculated orbit and thus strongly rotated around its axis, “it is safe to say that the separation of spacecraft from the third stage of the launch vehicle was something like an explosion.” He added that the data available is not enough to say for sure that it exploded. As they accumulate will be conducted mathematical modeling.

Start carrier rocket “Soyuz-2.1a” the ship “Progress” from the Baikonur Cosmodrome on April 28 at 10:09 MSK. The docking with the ISS has been scheduled for 16:07 MSK. However, after the separation of the third stage of the rocket from the unit ceased to act telemetry. After unsuccessful attempts to regain control of the ship in the MCC refused to take further action. “Progress” has started an uncontrolled descent from orbit.

According to the preliminary analysis of the Russian Space Agency, during additional testing of systems and components of the ship have been installed failures of individual components and assemblies cargo vehicle. Furthermore, the lack of tightness lines revealed propulsion unit. It was recorded outflow of gas from the pipelines of the ship.
