Mission description
Third test flight of the Shenzhou spacecraft, without crew on board. Main objective of the mission was to test the systems required to support a human in space. A human dummy was carried in the descent module to simulate the physiological signals of a human. 44 different experiments were carried, including an imaging spectrograph, cloud sensor, radiation sensor, solar ultraviolet monitor, solar constant monitor, atmospheric composition detector, atmospheric density detector, multi-chamber space crystallization furnace, space protein crystal equipment, a cell bioreactor, a solid matter tracking detector, and a microgravity gauge. Also on board was a video camera that broadcast images of the Earth as seen through one of the windows on the spacecraft.
