About this place

Xichang satellite launch center( or Xichang sitellite space center ) was built in the early 70's, officially opened in November 1, 1984, is the only open high-tech space as tourist attraction .the Center has a test launch, command and control, tracking and communications, weather, technical service support system, it can launch a variety of satellite, after 20 years of construction, has become the world's top space launch site. it is China's first launch center. The launch site is located in the city of Xichang in the territory of 60 km north of Mianning County in the valley, with an average altitude of 1500 meters.
Xichang Satellite is mainly used for launching geosynchronous satellite launch, but also the sun synchronous orbit satellite and low earth orbit satellite.

In 1990, the center sent the USA manufacturing Asian 1  satellite into a geosynchronous transfer orbit
24 Oct, 2007, the center launch successfully China first lunar orbiter Chang'e 1
1 Oct,2010, successful launch Chang'e 2
2 Dec,2013 successful launch Chang'e 3

"There are three superior conditions of natural emission field": 1.the low latitude (28.2 degrees north latitude), high altitude (1500 m), emission angle,  a short distance from the equator ground to air, at lower latitudes, closer, which can make full use of the centrifugal force of the earth's rotation, and can shorten the ground to satellite orbit distance,  in order to save the rocket effective load.

2. the canyon terrain, geological structure is solid, the overall layout to launch, launch facilities, technical equipment and tracking measurement on the ground, communication network, the construction can meet the multiple launching site.

3. the good weather, "launch window". The annual average temperature is 18 degrees Celsius, it is one of the smallest area of national climate change, sunshine up to 320 days, almost no fog, more time to test cycle and launching .

Gernerally speaking : low latitude, high altitude, low clouds, no pollution, air transparency is good.
