Excuse me, where are the four space launch centers in China?

About 95% of the sub-bases are located in Jiuquan City and 5% in Alxa League.

2. xichang satellite launch center

Xichang satellite launch center, China Satellite Launch Base, was built in 1970 and delivered in 1982. It is located in Mianning County, Liangshan Yi Autonomous Prefecture, Sichuan Province.

3. Taiyuan Satellite Launch Center

Located in kelan county Plateau, Xinzhou City, Shanxi Province, it is located in the temperate zone, with an altitude of about 1500m, and adjacent to Luya Mountain Scenic Area. It is one of the launch test bases for experimental satellites, applied satellites and launch vehicles in China.

Taiyuan Satellite Launch Center has multi-directional, multi-orbit, long-distance and high-precision measurement capabilities, and undertakes the launching tasks of all kinds of medium and low orbit satellites and launch vehicles such as meteorology, resources and communication in sun-synchronous orbit. The launch center was established in 1967. Winter here is long without summer, and spring and autumn are connected. The frost-free period is only 90 days, and the average annual temperature is 5℃.

4. Wenchang Satellite Launch Center

Located in Longlou Town, Wenchang City, Hainan Province, China, it is the first coastal launch base in China and one of the few low-latitude launch sites in the world. The launch center can launch the Long March 5 series rockets and the Long March 7 launch vehicle, and mainly undertake the launching tasks of spacecraft such as geosynchronous orbit satellites, large-mass polar orbit satellites, large-tonnage space stations and deep space exploration satellites.

Extended data:

Site selection conditions of satellite launch center

1. Latitude condition: low latitude, high linear velocity of spacecraft and high initial velocity, saving fuel and reducing launch cost.

2. Climatic conditions: dry climate, less precipitation, sunny weather and high air visibility.

3. Terrain conditions: open and flat, with relatively high surrounding terrain.

4. Transportation conditions: convenient transportation and convenient transportation of instruments and equipment.

5. Safety conditions: sparsely populated to ensure safety.
