CASC 1999

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.

Upcoming Spaceflights


Long March 5B | Xuntian Telescope

China Aerospace Science and Technology Corporation | China
Wenchang Space Launch Site, People's Republic of China
TBD December, 2027
Status: To Be Determined
Mission:

Xuntian, formerly known as the Chinese Space Station Telescope (CSST), is a Chinese space telescope designed to perform high-resolution, large-area, multi-band imaging and slit-less spectroscopy surveys of the sky at ultraviolet to infrared wavelengths of 255 – 1000 nm. The survey camera is slated to cover approximately 17500 square degrees of the sky in various bands, reaching maximum magnitudes of about 26. Xuntian will carry a survey camera, a tera-hertz receiver, a multi-channel imager, an integral field spectrograph, and a cool planet imaging coronagraph. Xuntian will be launched to a Low Earth Orbit that will be co-orbiting with the Tiangong space station/Chinese Space Station, which will allow for periodic docking with the station for regular maintenance by astronauts.
