Thevery first satellite launched by the USSR in 1957 helped to advance the understanding of the upper atmosphere. Since then, Russian spacecraft have been making significant contributions in the mankind's understanding of the Solar System and the broader Universe. The Earth-orbiting satellites studied cosmic radiation, distant objects and physical phenomena in deep space. They also helped to advance material science and space biology.

The Granat X-ray observatory launched on Dec. 1, 1989, became one of the last major scientific satellites operating in orbit before the fall of the Soviet Union.

On August 29, 2006, speaking at the 5th International Aerospace Congress in Moscow, Deputy Chief of the Federal Space Agency, Vitaly Davydov said that a fleet of three astronomy observatories of the Spektr series, along withKoronas-Foton and Intergelio-Zond spacecraft were promised funding.

A Russian rocket lifted off with a cluster of five satellites, among them a pair of new-generation spacecraft inaugurating platforms for future scientific and commercial applications.

ASoyuz-FG/Fregat rocket blasted off fromSite 31 inBaikonur on July 22, 2012, at 10:41:39 Moscow Time, carrying RussianKanopus-V No. 1 remote-sensing satellite along with a similarBKA spacecraft built for the government of Belarus. As secondary payloads, the mission carried a RussianMKA-FKI science satellite, an exactView satellite for a Canadian company and a TET-1 experimental satellite funded by the German space agency, DLR.

According to the Russian space agency, theFregat upper stage separated from thethird stage of the launch vehicle at 10:50 Moscow Time and started its own flight including five firings of its main engine.

All five payloads reached orbit successfully. BKA separated from the Fregat at 11:26 Moscow Time, followed by Kanopus-V at 11:31, TET-1 at 11:33, exactView-1 and MKA-FKI at 13:00:33 Moscow Time, when flying over the Pacific Ocean beyond the communication range ofRussian ground stations. The Fregat upper stage then conducted a deorbiting maneuver and reentered the Earth atmosphere at 13:50:53 Moscow Time. A ground control team responsible for MKA-FKI spacecraft confirmed establishing normal contact with the satellite shortly after it had entered the communication range at 13:55:21 Moscow Time. Industry sources also reported that Kanopus and BKA satellites estblished contact and downlinked telemetry during the second orbit of the mission.

Both Russian spacecraft onboard this Soyuz rocket represented new types of standard carriers, which are scheduled to be customized for future missions. TheKanopus platform is intended primarily for remote-sensing commercial applications, while a smallerKarat bus is well suited for a wide variety of low-cost science experiments. Both platforms already have a backlog of future missions waiting for launch.
