The Russian military satellite Kanopus-ST jointly with the  upper stage Volga lost orbit and burned in the Earth atmosphere over Atlantic.

      It was reported to TASS by a high-ranking source at the headquarters of the Aerospace Forces of Russia.

      The Soyuz-2.1 spacecraft with two military satellites was launched from the Plesetsk Cosmodrome on December 5. It was reported that both the satellites successfully got to the intended orbits. Next day, however, several media stated that one of the satellites had failed to separate from the  upper stage Volga. The source in the ASF headquarters confirmed that the device was lost. The reason for the emergency situation was that one of the four locks holding Kanopus did not work.

      The launch of Kanopus became the second one for the Soyuz-2.1 spacecraft, which is undergoing flight development tests in Plesetsk. For the first time this carrier was launched in December, 2013.
