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.
The project was also supported by the Krasnoyarsk science center of the Siberian Section of the Russian Academy of Science, RAN.
According to industry sources, ISS Reshetnev hoped to eventually market the Yubileiny/MiR platform to commercial users around the world. A modular service module of the satellite was designed to be adaptable for different architectures reaching around 100 kilograms. The basic satellite was expected to have a mass of 48 kilograms.
Mission of Yubileiny-1
2008 May 23: A converted ballistic missile delivered a cluster of satellites, after a successful launch from Russia's northern cosmodrome. The Rockot booster lifted off from Plesetsk on May 23, 2008, at 19:20:09. The vehicle carried a trio of Strela-3/Rodnik satellites along with the Yubileiny experimental spacecraft.
The separation of three Strela satellites from Briz-KM upper stage was scheduled for 21:04:18 Moscow Time on May 23, 2008. The separation of the Yubileiny spacecraft was scheduled for 21:05:08. The maneuver of deorbiting of the Briz-KM upper stage was scheduled between 21:15:15 and 21:16:55 Moscow Time.
The launch was previously expected at the end of 2007 and on Feb. 28, 2008.
Mission of Yubileiny-2
2012 July 28: More than a year and a half after a launch failure, Russia's Rockot booster returned to flight Saturday successfully delivering four satellites.
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 MiR/Yubileiny spacecraft was designed to function for one year, however in February 2013, a poster on the online forum of the Novosti Kosmonavtiki magazine reported that just a single passive system had remained functioning onboard the satellite.
