The cause of the fall of a military satellite “Canopus”, probably was a failure in its control systems, said “Interfax” sources. A source close to the Commission investigating the incident, said that accurate data on the composition of the emergency management system satellite is now being investigated.

He noted that the predecessor of “Canopus-ST” satellite “Canopus-B” – almost all elements of the control system were supplied by the British satellite company SSTL, among which sensors: star sensors, sun sensors, magnetometers, actuators – gyros, and an onboard computer system and its software.

December 5 the new rocket “Soyuz-2.1 b” with the two military satellites launched from the Plesetsk cosmodrome in the Arkhangelsk region. The press service of the defense Ministry hurried to report on the success, saying that both devices have successfully entered the calculated orbit. But then it turned out that one of the satellites dual use “Canopus-ST”, which among other things, the military hoped to detect a foreign submarine in the immersed state, is not separated from the block of removal “Volga”.

Later the interdepartmental Commission at the Plesetsk cosmodrome admitted “Canopus-ST”, which is preparing to launch nearly 15 years, lost. Representatives of rocket and space industry reported that the cause of the problem is already pre-installed – didn’t work one of the four locks holding “Canopus”.

December 8 a source in the headquarters of the aerospace forces (VKS) Russia reported that “Canopus-ST” in conjunction with “the river” came down from orbit and the debris burned in the dense layers of the atmosphere over the Atlantic ocean. The second satellite of the defense Ministry, launched with the “Union-2.1 b” to launch managed.

Meanwhile, it is worth Recalling that in may of this year a complete failure over the launch from Baikonur rocket “proton-M” with the Mexican communications spacecraft MexSat-1. In the Russian Federal space Agency and the international Commission of the cause of the accident has seen in a constructive errors of the creators of the booster.

The “Canopus-ST” preparing to launch nearly 15 years. Development of the device began in the early 2000-ies, in the past four years has conducted its finalisation and preparation for start-up. “Canopus-ST” was equipped with a multispectral camera, the microwave radiometer with a swath 2200 km and a spatial resolution of 12-160 kilometers. The satellite was designed to explore the ocean. In particular, using this device was intended to detect submarines in the submerged condition.
