Yubileiny-2/ MiR (Mikhail Reshetnev) Microsatellite
Yubileiny-2/MiR is a follow-up mission of Yubileiny which was launched on May 23, 2008. Yubileiny-2/MiR is a Russian technology development microsatellite which was designed and built jointly by the JSC-ISS (Joint Stock Company-Information Satellite Systems), named after academician Mikhail F. Reshetnev (the founder and the first director of the company), and SibSAU (Siberian State Aerospace University) of Krasnoyarsk. 1)
The objectives and tasks of the program for creation of the scientific and educational, technological microsatellites series being implemented:
• development of the integrated system of the engineering education (distance learning system, laboratory sessions performing using the ground stations of microsatellites control etc.)
• implementation of the design-oriented educational technology during formation of the space domain specialists professional capacities (students’ participation in designing and manufacturing of satellites, service systems and scientific devices)
• scientific experiments in space (development of the Earth natural resources space monitoring methods, multifunctional nanomaterials, high-temperature superconductors and other intelligent materials use in space)
• technological development and obtaining of the flight qualification for the advanced service systems, devices and elements of the satellites (of the attitude determination and control subsystem, electric power subsystem, thermal control subsystem and other subsystems with the increased lifetime).
The microsatellite MiR (Mikhail Reshetnev) is designed on the base platform of the Yubileiny (or Yubileyniy) satellite with extended mass and power performances.
The students of SibSAU have developed and manufactured: OBC (On-Board Computer), remote data interface unit, Earth remote sensing camera and laser corner reflector intended to measure the distance from the satellite to the Earth. The function of the devices is the integration and accommodation of the new control unit and the digital line of the Earth remote sensing information transmission in space.
Note: A proper spacecraft description will be provided when enough information is available.
65 kg launch mass (platform= 30 kg, payload = 35 kg)

Spacecraft design life
The Yubileyniy-2/MiR spacecraft was launched on July 28, 2012 as a secondary payload on a Rockot/Briz-KM vehicle from the Plesetsk Cosmodrome, Russia. Launch provider: Eurockot Launch Services GmbH, a German-Russian joint venture owned by EADS Astrium and by Khrunichev State Research and Production Space Center. 2)
The primary payloads on this flight were:
- Gonets-M No.3, and Gonets-M No.4 communication satellites of Roskosmos. The spacecraft were built by JSC Academician M.F. Reshetnev Information Satellite Systems, the system operator is the Gonets Satellite Company.
- Strela-3/Rodnik (military reconnaissance satellite built by NPO Prikladnoi Mekhaniki). The Rodnik spacecraft will become a part of the Strela constellation of Ukrainian military communications satellites.
Orbit: Near-circular orbit, altitude ~ 1400 km, inclination = 82.5º, period = 115.8 minutes.
This launch marked the return-to-flight mission for the Rockot launcher that suffered a failure on its previous mission on February 1, 2011 when the upper stage of the launcher encountered a malfunction, placing the payloads in a lower-than-planned orbit. After the failure, the manufacturer of the launcher and upper stage, the Khrunichev State Research and Production Space Center, suspended Rockot launches to investigate the cause of the premature shutdown of the Briz-KM upper stage. After the cause of the failure was found, Rocket was approved for flight once again (Ref. 2).
Camera D33 is an experimental video camera developed by the SibSAU. The objective is to test the camera performance for Earth observations. The results of this experiment will be analyzed and used later in designing the camera D33 production samples.
Two experimental surveillance WEB video cameras are installed. The goal of this experiment is the integration of the space technology into the framework of the Yubileyniy-2 satellite deployment mechanisms, and to monitor the performance of the surveillance WEB video cameras.
PS (Pressure Sensor)
PS is an experimental device developed by specialists of the Novosibirsk State University. The objective of this experiment is the integration of the technology of pressure measurement inside the unpressurized instrumentation module and the performance of the sensor flight tests. The device measures the residual pressure (in the range from 1 x 10-5 to 760 Torr) on the satellite and the sensor package temperature (in the range from -10 to 55ºC). Structurally, the PS-905 consists of the one unit.
