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 Wenchang Space Launch Site is a rocket launch site located in Wenchang on the island of Hainan, in China. Formally a suborbital test center, it currently serves as China's southernmost spaceport. The site was selected for its low latitude, 19° north of the equator, allowing for larger payloads to be launched. It is capable of launching the Long March 5, the heaviest Chinese rocket. Unlike launch facilities on the mainland, Wenchang uses its seaport for deliveries.
