From 1970 to 12, xichang satellite launch center began to be established. Daliangshan site is famous for its high mountains and deep gullies, and the launch site is built in these deep mountains and old gullies. Therefore, people at the launch site today call themselves "people in the ditch". When they go out, they are called "going into the city" and when they come back, they are called "going into the ditch".

Catch sheep ditch, pineapple ditch, Yangjiagou ... In these unknown ravines, thousands of "ditch people" have gone through decades of struggle and created the China miracle of "deep ditch to high rail".

High orbit is the place where geosynchronous orbit satellites run. "Geosynchronous orbit resources are limited and the positioning technology is complex. Launching satellites in this orbit is an important step towards a space power. " Li is a senior "ditch man" and is currently the Deputy Minister of Planning Department of xichang satellite launch center. Li recalled that in 1970, under the command of the CPC Central Committee, a large number of entrepreneurs marched into Xichang, which opened a new "Long March" in China's space industry where the Red Army passed. "These entrepreneurs of the older generation in Xichang worked hard and successfully sent China's first experimental communication satellite to an altitude of 36,000 kilometers in 1984." Li said, with this as a symbol, China Aerospace officially has the high orbit launch capability.

Since then, every geosynchronous orbit satellite in China has been launched by xichang satellite launch center. Before the completion of Wenchang launch site, Xichang was the only high-orbit launch site in China. Because xichang satellite launch center has developed a unique skill-launching low-temperature fuel rockets, Changsanjia series rockets can only be launched by xichang satellite launch center. Because of this, all the 43 Beidou navigation satellites that China has launched have "taken off" from xichang satellite launch center.

Up to now, xichang satellite launch center has carried out space launch missions, accounting for almost half of China's space launches, which is the most frequently launched by all launch centers. It has the full launching capability of Long March series liquid rockets, stable "zero window" launching capability and continuous launching capability with the shortest interval 15 days.

In addition, Xichang launch site has achieved an important leap from single launch to multiple launches, from launching geosynchronous orbit satellites to launching multi-orbit spacecraft, from 2-3 launches per year to more than 15 launches per year, from near-control test launch to remote control organization and command.

From the boudoir to the world, 33 alien launch missions have been carried out.

As the first of the four launch sites in China, China's space strength and brand image are displayed to the whole world from here.

"I am an old man in the ditch." Ying Hongwei, a senior engineer from the Technical Department of xichang satellite launch center, is also a "ditch man" and 1986 came to the launch site. Since 1984 launched its mission for the first time, xichang satellite launch center has organized and implemented 125 space launch missions, among which 123 should be participated grandly.

"If we used to hide in the boudoir, then 1990 is the moment when we walked out of the boudoir." In Ying Hongwei's view, China Aerospace has been conducting research behind closed doors until now, and rocket technology is kept secret at home, not to mention facing foreigners. "The turning point of opening up is the successful launch of' Asia One'."

1985, the Long March rocket began to engage in commercial launch activities, and the door of China Aerospace opened. However, at that time, China Aerospace had no experience in international commercial launch, so everything was difficult at the beginning.

At this time, a satellite entered the field of vision of Chinese astronauts. This is the HS376 satellite (later renamed as "AsiaSat- 1") manufactured by Hughes Company of the United States. 1984, this satellite was launched by the space shuttle challenger, but it did not enter the scheduled orbit. Later, the space shuttle Discovery lifted off and brought the satellite back to the ground.

"At that time, the industry compared this satellite to a' disaster star', but we saw an opportunity." Ying Hongwei said that although it took a lot of twists and turns, China still got the right to launch the satellite, and finally, with the joint efforts of astronauts all over the country, it successfully put the satellite into the scheduled orbit at Xichang launch site. Satellite manufacturer Hughes said in his congratulatory message that the orbital accuracy of this launch exceeded that of any previous launch by Hughes.

From that moment on, China became the third country in the world and the first country in Asia to enter the international commercial launch market, and xichang satellite launch center officially went to the world. In 2005, Xichang launch site successfully launched 15 international commercial satellites such as "Asia-Pacific 6", which opened up a new market for launching non-American satellites.

Since/KLOC-0 was opened to the outside world in 1984 under the name of "xichang satellite launch center, China", Xichang has carried out 33 alien launch missions.

"Since the reform and opening up, we have overcome many difficulties and challenges, successfully launched the Long March series of launch vehicles to the world and opened up the international market." Ying Hongwei said that Asia No.1 was the beginning, and xichang satellite launch center made a stunning appearance in the world on behalf of China Aerospace. China's space market has gradually expanded to countries and regions in Europe, Asia and South America, and China's commercial launch contracting mode has been further expanded to include all-star export, all-star delivery and on-board launch. Now, China has successfully helped Nigeria, Venezuela, Pakistan, Bolivia, Laos, Belarus and other countries realize their "space dreams".

From the island to deep space, a center will build and manage two space launch sites at the same time.

"5, 4, 3, 2, 1, ignite!" 1 65438+1October1,the 4th Beidou navigation satellite in China was launched. As the first female "0 1" commander at the launch site in China, Zhang Runhong became a news figure for a time, and many netizens gave her a thumbs up. When talking about her husband Chen Xiaojun, the famous "Iron Lady" at Xichang launch site always said happily, "My husband is better than me."

Chen Xiaojun just transferred back to Xichang from Wenchang Space Launch Site not long ago, and the young couple ended the days of "seeing from two launch sites". Chen Xiaojun responded to the call to build a new launch site in Wenchang 20 12. In Wenchang, he grew from an ordinary post operator to a measurement system commander.

Behind the love story of the space couple is another China in xichang satellite launch center, a center that manages two launch sites at the same time. Today, xichang satellite launch center is responsible for the construction and management of two space launch sites, Xichang and Wenchang. It has 17 units, mainly distributed in eight cities (counties) in Sichuan, Guizhou and Hainan provinces, and consists of five systems: test launch, measurement and control, communication, meteorology and technical service guarantee.

One center, "two battlefields", now xichang satellite launch center is accelerating its March to build a world-class launch site. No.3 station of Xichang launch site is known as "meritorious tower" and No.2 station is known as "the first tower in Asia". The two launch pads have been through many battles, sharing weal and woe. In 2009, it was awarded as one hundred classic excellent projects for the 60th anniversary of the founding of New China. Wenchang Space Launch Site has two launch stations, Long March 7 and Long March 5, and adopts a brand-new "three vertical and one far" experimental launch mode, which represents the latest technology and the highest level of space launch in China.

Wenchang Space Launch Site is the first coastal launch base in China and one of the few low-latitude launch sites in the world. When completed and put into use, it will, together with Xichang launch site, carry the dream of China's space flight into a more distant deep space.

Deep space exploration is an important symbol to measure the strength of space, and lunar exploration is the first step into deep space. All the launches of China's lunar exploration project were undertaken by xichang satellite launch center, and were carried out at Xichang launch site in the early stage.

In the Chang 'e-1 mission, xichang satellite launch center put forward the "zero window" launch target for the first time, and all the system personnel kept pace, and tens of thousands of devices were not bad every minute, thus realizing the Chinese nation's Millennium dream of flying to the moon. During the Chang 'e II mission, the center grasped the best launch opportunity, saved a lot of fuel for the satellite, enabled China to detect the Lagrange point for the first time, and extended the space reach of China to 654.38 billion kilometers. The Chang 'e III mission once again realized the "zero window" launch, which created the best conditions for the probe to run to the moon and also created the best orbit for the lunar landing.

In May this year, the relay star "Queqiao" of Chang 'e IV was sent into space. Not long ago, the Chang 'e IV probe was successfully launched. According to the relevant person in charge, with the full maturity of Wenchang Space Launch Site, it will take over the baton from Xichang in the future and undertake the third phase of the lunar exploration project, expanding the pace of China's space exploration to more distant deep space such as Mars. In the future, China's Mars probe will also be launched here.
