Mission
TJSW-20
- Type: Government/Top Secret
- Orbit: Geostationary Transfer Orbit
Chinese classified satellite claimed to be for communication technology test purposes. Actual mission not known.
Location
101
Wenchang Space Launch Site, People's Republic of China
101 has witnessed the launch of 17 rockets, including 17 orbital launch attempts. While Wenchang Space Launch Site, People's Republic of China, has been the site for 57 rocket launches.
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.
Rocket
China Aerospace Science and Technology Corporation Long March 5
Long March 5 is a Chinese heavy lift launch system developed by China Academy of Launch Vehicle Technology (CALT). CZ-5 is the first Chinese vehicle designed from the ground up to focus on non-hypergolic liquid rocket propellants. Currently, two CZ-5 vehicle configurations are planned, with maximum payload capacities of ~25,000 kilograms (55,000 lb) to LEO and ~14,000 kilograms (31,000 lb) to GTO. The Long March 5 roughly matches the capabilities of American EELV heavy-class vehicles such as the Delta IV Heavy.
Agency
China Aerospace Science and Technology Corporation
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.
