On September 19, 2015 at 23:01 UTC (on September 20 at 07:01 Beijing time) the “Long March – 6” (“Changzheng-6”) rocket-carrier was launched from the Taiyuan Satellite Launch Center in north China's Shanxi Province. The rocket orbited 20 small satellites. Some of the 20 satellites sent into space went up housed inside mothership satellites, where they were stowed for later deployment. Many were assembled by students at Chinese universities. They will conduct technology demonstrations in orbit, including tests of electric propulsion, in-space communications links, new software and cameras, nanotechnology, and amateur radio relay. The following satellites were orbited: Xinyan-2; Lüliang-1; Naxing-2; Zheda Pixing-2A, -2B; Zidingxian-2; Xiwang-2A, -2B, -2C, 2D;… The 20 satellites are the most number of satellites ever launched on a single rocket by China.
