Glonass-M, also known as Uragan-M, are the second generation of Uragan satellite design used for GLONASS satellite navigation system. GLONASS is a Russian space-based navigation system comparable to the similar GPS and Galileo systems. This generation improves on accuracy, power consumption and design life. Each satellite weighs 1415 kg, is equipped with 12 L-band antennas, and has an operational lifetime of 7 years.
Medium Earth OrbitThis is the first docking mission for China's Shenzhou program. Being the first spacecraft to visit the Tiangong-1 space station, it was launched without crew to demonstrate spacecraft rendezvous and docking techniques. The spacecraft docked automatically to the station on 2 November 2011. A second undocking and re-docking to test accuracy and reliability of equipment and sensors in a bright environment was performed on 14 November 2011. Shenzhou 8 undocked on 17 November 2011 and landed safely back on Earth the same day.
Low Earth OrbitThe first two In Orbit Validation satellites of the Galileo constellation. The Galileo constellation is ESA's satellite navigation system and is expected to be completed by 2020. Galileo will provide Europe with an alternative to the American GPS and Russian GLONASS constellations, but will be interoperable with both systems. First launch of the Soyuz rocket from the Guiana Space Centre.
