Radio Sputnik 40 - Yubileiny-2
NASA Catalog: 38735
The light-weight launcher lifted off on July 28, 2012, at 05:35:00 Moscow Time (01:35 GMT) from Pad 3 at Site 133 in Plesetsk. According to official reports, it carried a pair of Gonets-M communications satellites for the Gonets-D1M multifunction network, MSPSS, and a MiR (Mikhail Reshetnev, a.k.a. Yubileiny-2) remote-sensing spacecraft. A classified military satellite was also announced to be onboard. According to Russian sources, it belonged to the Strela communications network and similar to civilian Gonets satellites. Russian space agency, Roskosmos, confirmed that both Gonets payloads and MiR successfully reached the orbit, separating from their upper stage at 07:19 Moscow Time on July 28. For Gonets the operational orbit has an altitude of 1,500 kilometers and an inclination 82.5 degrees toward the Equator. Industry sources confirmed that the first communication session between ground control and MiR (Yubileiny-2) satellite had been conducted successfully. The launch was previously planned for June 30, but slipped to July 13 and then to July 28, primarily due to issues with avionics onboard Rockot's Briz-KM upper stage.
The Yubileiny-2 experimental micro-satellite, later known as MiR, was designed for remote-sensing of the Earth among its goals. It was expected to be used for educational student projects. Siberian State Aerospace University, SibGAU, supplied key systems for the satellite, employing its students in various stages of the development process. SibGAU developed a laser reflector, the main payload control unit, a power supply unit, two small web cameras, remote-sensing camera for the satellite.
