The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program. It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.
The payload is an experimental reusable spacecraft. It is rumored to be a prototype of a reusable spaceplane (similar to Boeing X-37B vehicle). The spacecraft stayed in orbit for two days and returned to Earth on September 6. Though the landing site was not disclosed, the spacecraft is presumed to have landed at an airbase near Lop Nor nuclear test site.
