China's next Shijian-11 Satellite launched atop Long March 2C
Shijian-4 was delivered to orbit in 1994 and carried six payloads dedicated to the study of near-Earth space radiation.
The China Academy of Science built Shijian 5 to demonstrate a new satellite bus for future application in Low Earth Orbit mission. Additionally, the satellite featured six instruments for science experiments studying radiation and the microgravity environment.
Four pairs of satellites were launched between 2004 and 2010 serving undisclosed scientific purposes. Shijian-7 was a single satellite launched in 2005 carrying an infrared camera as well as other scientific demonstration payloads. Next up was Shijian-8 that flew a short duration mission in 2008 to demonstrate a re-entry capsule and all its associated systems in preparation for sample returns from the moon. The capsule carried plant seeds and organisms that were exposed to the space environment and returned to Earth for post-flight studies.
The Long March 2C is a member of the Long March Rocket family and was derived from the DF-5 Ballistic Missile. CZ-2C is a two-stage Rocket standing 39.93 meters tall and it has a diameter of 3.35 meters with a liftoff weight of about 233,000 Kilograms. It is an often used member of China's workhorse launcher family.
Both Stages of the Long March 2C use Nitrogen Tetroxide and Unsymmetrical Dimethylhydrazine as propellants while an optional third stage in the SMA version of the launcher uses solid propellant. The first stage of the stack is 25.72 meters long and 3.35 meters in diameter with a launch mass of 171,300 Kilograms that includes 162,700 Kilograms of propellants.
