Tengfei History will speak 史 | The wreckage of the rocket, witness the guardianship of the mountains and wading

Speak hard, sigh, fearlessness, and danger.

At the History Exhibition Hall of the Xichang Satellite Launch Center, there is such a rocket wreckage, describing a history of the Xichang astronauts' hard struggle to carry out the work of the landing area.

This photo shows the grid of the Long March 2 Cross Rockets.

On July 26, 2019, the center successfully launched the remote sensing 35 group 05 satellite. This grid rudder dropped in the mountainous area of ​​Guizhou during the rocket flight. According to reports, the main function of grid rudder is when the rocket wreckage enters the atmosphere, adjusting the air resistance and lift direction by controlling the posture, changing the trajectory of the rocket wreckage, so that the wreckage can fly towards the scheduled area, and realize that the area of ​​the landing area will be from hundreds of square meters from hundreds of square meters. The kilometers are reduced to a few square kilometers, so that the scientific and technological personnel can accurately carry out the evacuation and wreckage recycling of the Rockets.

And this work is the settlement of the Guiyang Observation Station of the Xichang Satellite Launch Center.

The working group in the landing area is looking for the wreckage of the rocket

Time to trace, in March 1978, Guiyang Observation was established in Xichang, Sichuan, and moved to Huaxi County, Guiyang City, Guizhou Province in March 1979. Here, the wreckage recycling during the rocket launch is an important task. When the Rockets lift off at the Xichang launch site, the wreckage area covers 59 counties (cities) in 9 provinces including Guizhou, Hunan, Sichuan, and Jiangxi, about 30,000 square kilometers, and more than 7.5 million people. Along the way, the work group of the landing area is "suffering, sighing, fearlessness, and dangerous". It is a hero who dare to fight hard and cooperate.

It turned out that the Guizhou landing area belonged to the typical Karst landforms, with complex geographical environment, poor signal in mountainous areas, and navigation positioning software often shifted. If you do not pay attention, you may receive the work group of the landing area to the “Jedi” that can be left without a way. Essence

Rocket wreckage in the mountains

In order to clarify the terrain of the landing area, the most of the astronaut phone in the setting area is the map software in order to clarify the terrain and local fabrics of the setting area. The topography of the terrain and the landforms, after arriving at the landing area, check the local government's topography information, and visit the masses to ask about the mountain forest road where they can reach ... These are the essential tasks of their mission every time.

They are known as the "living map" walking in the landing area. During the search of the wreckage in the mountains of Qiandongnan Prefecture, the local guidance was dizzy by the clusters of bushes, and it was fascinated in the mountains. At the critical moment, the "Living Maps" relying on the accumulated topographic and local information, assisting the simple map of the marked marked, calmly sorted out a "sheep intestine road" in the predicament, and arrived smoothly to the rocket wreckage. Half an hour.

Afterwards, the guide asked them: "The villagers are dizzy, do you know?" The astronauts laughed and said, "We just traveled this path in our heads many times."

Notify the masses to evacuate on time

In recent years, the space launch mission of Xichang Satellite Launch Center is very dense, but the landing area has still achieved the goal of "no casualties, no major property losses, no major public opinion". Behind the grade is that the workers in the landing area are tirelessly paid. Every time the evacuation work is carried out, the working group of the landing area will be households from households, and they will be arranged one by one. They repeatedly, and the people of the landing area will clarify the significance of the national launch satellite and avoid the necessity of avoiding the falling wreckage in a timely manner. They said, "One more words, you can remind you, understand one more, less gap, and less loser."

Carry out the propaganda work of the landing area

Stepping on the bumps into avenue, the more difficult it is. At the same time, because of the needs of the space industry, the settlement of the settlement area has been running in the landing area for more than a hundred days. Facing ultra -high -density aerospace launch tasks, they are either working in the sunset or on the way to the landing area. There are very few time to accompany your family.

Because of the long -term outburst, comrades of the settlement of the settlement area have become "Son of Voice", "Video Husband", "Photo Dad" ... But in accordance with the belief of "must not lose the masses", they climb the mountains, crosses the rush, cross the suspension bridge, and cross the suspension bridge , Diamonds, turning loyalty to the party into a full enthusiasm for the people, and pouring all their efforts in the aerospace cause of the motherland.

When the rocket dragged orange -red tail flames across the sky, the settlement of the landing area was already on the way. They used the rush and persistence to build a "security barrier" for the people ...
