Xichang and Jiuquan

Xichang is in Mianning County, Liangshan Prefecture, Sichuan Province.

Jiuquan is in Gansu, but Jiuquan launch center is in Ejina Banner, Alxa League, Inner Mongolia.

But I think the geographical location is too far-fetched.

As we all know, the closer a satellite is to the equator, the better.

I think it should be that China kept the army quite secret at that time, but of course it hasn't changed now, so we are looking for sparsely populated and relatively secret places, and we can see from the names that they are all avoiding real addresses.

Xichang: First, China's first geosynchronous orbit satellite was successfully launched on June 8,1984; Secondly, 1,1In February 1986, China's first communication and broadcasting satellite Dongfanghong II was successfully launched, ending the history of renting foreign satellites to watch TV in China. The TV programs and weather forecasts we are watching now are transmitted by our own satellite. These satellites were all launched from here with the launch position of the third child. Third, the commercial satellite contracted by China was successfully launched in 1990. Asia One and Asia One are made in Houston, USA. It can be said that they were called "catastrophe" at that time, but they were not successfully launched in five countries. Later, it was captured by the space shuttle and successfully launched from the third launch tower on April 7, 1990. So it is the meritorious tower. It's time to retire now.

Xichang satellite launch center was founded in 1970 and put into use in 1982. Since 1984+ 10 launched China's first communication satellite, 28 domestic and foreign satellites have been launched. 1985- 10, XSLC officially opened to the outside world, undertaking the business of launching extraterrestrials and receiving technical exchanges and inspection teams from more than 50 countries and regions. Advanced and reliable facilities and conditions provide safe and high-quality services for the launch of aliens. Since 1984, xichang satellite launch center has launched 17 communication satellites at home and abroad, which shows that China is one of several important countries in the world that have mastered the capability and technology of commercial launch and occupies a place in the field of world space city. With the acceleration of the construction of Xichang Aerospace City, the rise of Xichang inland open city, and the establishment of the national first-class air port of Xichang Qingshan Airport, xichang satellite launch center has left a good impression and memories for many visitors.

Since 1984 successfully launched the first experimental communication satellite, by the end of 2003, 34 satellite launches had been successfully organized at home and abroad. 1986, Xichang Satellite Launch Site was officially opened to the public. The launch center was completed at 1983. Since 1984, China's first experimental communication satellite, practical communication broadcasting satellite and practical communication satellite have been launched one after another. 1990, the American-made "Asia 1" communication satellite was sent into geosynchronous transfer orbit. In April 2004, "Experimental Satellite No.1" and "Naxing No.1" were successfully launched in xichang satellite launch center, which was the first time that the center launched a sun-synchronous orbit, which indicated that the space launch capability of the center was further improved and it could launch multi-directional and multi-orbit satellites. As of April 2004, the center has two independent launch stations, which can launch different types of Long March launch vehicles, send large-tonnage satellites into synchronous transfer orbit and send small satellites into sun-synchronous orbit.

On June 24th, 2007 18: 05: 04 (UTC+8: 00), China's first man-made satellite around the moon, Chang 'e-1, was launched in xichang satellite launch center, and the whole "flying to the moon" took about 10- 12 days. It is estimated that the total weight of the satellite is about 2350kg and its service life is more than 1 year. The main detection objectives of the satellite are: to obtain three-dimensional images of the lunar surface (the first three-dimensional image of the lunar surface is expected to be sent back in late 165438+ 10); The contents and distribution characteristics of four useful elements (K, Th, U, O, Si, Mg, Al, Ca, Fe, Na, Mn, Cr, GD) on the lunar surface are analyzed. Detect the thickness of lunar soil and the space environment from the earth to the moon.

Jiuquan: Over the past decades, Jiuquan Satellite Launch Center has established a relatively complete set of comprehensive launch facilities and has an excellent scientific and technological team. Thirty-seven satellites were launched one after another, creating many firsts in China's space launch history:1960165438+10. On October 5th, the first surface-to-surface missile made in China was successfully launched here. 1966101October 27th, China's first missile nuclear weapon test was also successful here. Since1April 24, 970, when the Long March-1 carrier rocket successfully launched China's first satellite, Dongfanghong-1, Jiuquan Satellite Launch Center has successfully launched more than 20 scientific experimental satellites with Long March-1, Long March-2 C and Long March-2 D rockets. 1975165438+1October 26th, China's first recoverable satellite was successfully launched here. 1In August, 1987, Jiuquan Satellite Launch Center provided launch services for the French company Matra, which made China's space technology go global. 1980 On May 18, China's first long-range launch vehicle was successfully launched here. 1992 10, Jiuquan Satellite Launch Center carried out the launch mission for international users for the first time, that is, when China's recoverable satellite was launched by the Long March II C rocket, the Feullias satellite of Swedish Space Company was launched into the scheduled orbit and was successful. 1999165438+1On October 20th, the Shenzhou experimental spacecraft was launched from here, which opened the curtain of China's manned spaceflight project. Since then, Shenzhou II, Shenzhou III, Shenzhou IV, Shenzhou 5, Shenzhou VI and Shenzhou VII have been successfully launched from here.
