SAST has been in charge of the development of the manned spacecraft, cargo spacecraft, space laboratory, and space station core module, experimental module I, and experimental module II, optical module in the China’s Manned Space Program. SAST plays a supportive role in this program in developing several subsystems, such as propelling/resource modules, power, docking mechanism, digital transmission and communication subsystem. Meanwhile, SAST is a major force for the overall design of the space station experimental module II.
So far, SAST has made a significant contribution to the program. Missions accomplished include the launching of spacecrafts from SZ-1 to SZ-11, target aircraft TG-1 and space station TG-2, spacewalk and docking and supplementation propellant for the cargo spacecraft (TZ-1).
