Shijian 1



Shijian 1 was a Chinese experimental satellite launched on a LM-1 booster into a 265 x 1825 km orbit inclined at 69.8 deg. The mission was to broadcast stored messages. It broadcast messages for 12 days when the batteries apparently failed. Other reports claim the satellite operated for eight years. The satellite bus was similar to that of DFH-1, with the addition of solar cells. The satellite was launched from the Shwanf Chengtze Space Facility in northwest China.
