Russia put into orbit from the Plesetsk military satellite – BBC News

A military satellite “Cosmos-2506″ was successfully launched into orbit from the Plesetsk cosmodrome in the Arkhangelsk region. The satellite went into the calculated orbit and adopted by the management of troops Aerospace Defense of Russia.

The onboard systems of the spacecraft are functioning normally, with the spacecraft established and maintained a stable telemetry, Tass reported.

A military satellite into space led rocket “Soyuz-2.1b.” It was launched from Baikonur in 19 hours 44 minutes Moscow. Ten minutes after the satellite was in orbit.

This is the first launch in 2015, “Soyuz-2.1b” and the launch of the second war in June. June 5 was launched from Plesetsk “Soyuz-2.1a” with the military apparatus. This was the first launch of the accident with a truck “Progress M-27M”. Total in 2015 from the Plesetsk cosmodrome was four missile launch three rockets launch “Soyuz-2″ and one rocket “Rokot”.

“Soyuz-2.1b” – modification of a space rocket “Soyuz-2″ , the name of developmental work – “Rus”. It was created in the mid-1990s on the basis of operated since 1973. “Soyuz-U”. Over 39 years of use were conducted from Plesetsk launch 434 “Soyuz-U” into orbit were put 430 satellites of various purposes.

“Soyuz-2.1b” – a three-stage rocket of the middle class. The starting weight – 312 tons, maximum length – 46.3 meters. The missile is produced in Samara and is equipped with a control system based on digital computer “Malachite-3″ Scientific-Production Association of Automation named after Academician NA Semikhatova (Yekaterinburg). On the first and second steps are applied liquid rocket engines RD-107A and RD-108A Khimki NPO Energomash, the third stage – four-chamber RD-0124 Voronezh Chemical Automatics Design Bureau.

The fuel is kerosene. Its liquid oxygen oxidizer acts. On the “Soyuz-2.1b” may be applied fairing diameter of 2.7 or 3 meters, as well as 3.3, 3.715 and 4.11 meters.

The launches “Soyuz-2.1b” and go from Baikonur Plesetsk. The upper stage rocket can work “Frigate” NGO named SA Lavochkin or “Volga” RCC “Progress”.
