Vol 4 Chapter 2357: Yatuhai Landing Field

As the team drove over the entire dune, Wu Hao saw a vast flat Gobi Desert. At this moment, the entire Gobi Desert is covered with a thin layer of snow, and the gravel below can be clearly seen.

In the middle of the Gobi Desert, there are three huge landmarks, which are very eye-catching.

The first is the two landmarks on both sides, which are actually a red and white "four-quadrant mark", much like the logo of a luxury car. However, this is indeed a measurement standard used in industrial photogrammetry, and it is also a visual identification reference point.

This four-quadrant marker will be used to identify the coordinates of the ground during the return and landing of the secondary rocket, as well as the reference point. It will be used for the adjustment of the position and flight attitude of the secondary rocket when it is landing, so as to control the smooth landing of the secondary rocket. above the landing point.

The other sign is actually a long line, and it’s also a long dashed line. This is actually a measurement baseline. Its function is the same as the four-quadrant mark, and it is used for the secondary rocket to measure its own landing flight speed and the deviation of the landing trajectory during the landing and landing.

The third one is the main landing site where the second-stage rocket will land. The entire shape is circular, and it is painted with red, yellow, white, black, and green from the middle to the outside. Concentric circles, Kind of like an arrow target.

In fact, the entire landing and landing process can be seen as an arrow shot from space, how to accurately 'stick' to the target.

At this moment, some construction vehicles are parked on the site, and many workers in orange down jackets are busy.

Looking at the convoy coming from a distance, everyone at the scene waved their hands and greeted excitedly. Seeing this, Wu Hao couldn't help but smile. Compared to being intrigued with some messy people and trying their best. He prefers to deal with this group of tech talent. There is no intrigue here, there is just a happy atmosphere where everyone works together for the same goal.

The convoy stopped in front of the landing pad, and several staff members in orange down jackets responded immediately.

When the car door opened, Wu Hao felt a chill, and the howling northwest wind made him froze. And he finally recognized their identities from the faces of the staff who were covering their faces.

Mr. Wu, welcome to come to Yatuhai for guidance work. It's been hard work along the way. Zhou Xiangming quickly took off his thick gloves, and shook hands with Wu Hao.

Wu Hao smiled and shook hands with the other party, and then said with a smile: "It is hard work for everyone to work in such an extreme weather environment. On behalf of the company, I would like to express my condolences to everyone."

At this time, Shen Ning, the secretary who was following behind, also walked over with a back orange down jacket and put it on him. This also made him warm up immediately, at least the cold wind couldn't get into his clothes.

Seeing this, Zhou Xiangming smiled and said, "It's cold here, so you should pay more attention to keep warm and don't catch a cold."

"I heard you say that this place is called Yatuhai, do you have any idea?" Wu Hao asked Zhou Xiangming while closing the zipper of his down jacket.

Hearing Wu Hao's culture, Zhou Xiangming, Yu Chengwu and others looked at each other and smiled, and they all laughed at will. Yu Chengwu led Wu Hao inside, and introduced to Wu Hao with a smile: "Yatu is the name of the Mongolian area, which means poor, while Haina generally refers to lakes. So the real name here is actually poor. ocean.

It is said that this place was a saltwater lake before the Ming Dynasty. The lake was bitter, there was no fish, and cattle and sheep could not drink, and it was surrounded by bald stones and no grass, so it was called Yatu Sea.

In the Ming Dynasty, in order to consolidate the northwest frontier fortress and resist the attack of the Tatar thorns, it began to renovate the frontier fortresses of the northwest generation, rebuild the Great Wall, and fill the borders with immigrants. The water became less and less, which also caused the area of ​​Yatu Sea to become smaller and smaller, until the Republic of China completely dried up.

So we are actually at the bottom of a dry lake, almost southeast. "

I said, how come there is such a large stretch of Gobi Desert here, it turns out to be a lake bottom. Wu Hao heard the words, looked at the boundless next door, and said with a smile.

At this time, Zhou Xiangming also opened his mouth and said to him: "Actually, there was originally a village here, but it was just because it was too difficult to get water, coupled with inconvenient transportation, and the natural environment was harsh.

So after 10 years, the local people relocated all the more than a dozen families of herdsmen living in this village to nearby towns.

over there…"

Zhou Xiangming pointed to the far south, and continued to Wu Hao: "This village is right there near the edge, there is a Danshui spring, and these dozen herdsmen live by this Danshui spring. Woolen cloth.

Now the houses over there have been abandoned and become a piece of broken eaves and walls, which can no longer survive.

It is said that a few years ago, there was a protection station for wild camels, but because the environment was too bad, it was also moved.

We were able to find this place by accident. The landing site that has been tested before is too close to the launch point, and the area is too small, and there are some towns nearby, so it is very troublesome to test every time, and it needs to be evacuated Residents of nearby towns.

So we have always wanted to find a landing site for the second-stage rocket to land, but it is really difficult to find such a large area of ​​no man's land and meet some other conditions.

By chance, our site selection and investigation team met a paleontological research team, and learned from their mouths that there is such a large dry lake, so we came to investigate with great joy and found that the environment here is very suitable for our construction. this landing pad.

So we communicated with the local authorities~www.readwn.com~ They are also very supportive for us to build this landing site. So we hit it off and decided to build a high-orbit return spacecraft vertical landing site here.

In the future, it will not only be used for the landing and landing experiments and related tasks of the returnable second-stage rocket, but also can be used for the landing and landing recovery tasks of the high-orbit of the first-stage rocket.

In addition to this, it can also be used for the landing needs of some of our returnable spacecraft. "

Speaking of this, Zhou Xiangming said with a smile: "In the future, there will be a dedicated road from the highway dozens of kilometers away from here to here, so that we can carry out the recovery and transportation of secondary rockets and other spacecraft.

The bottom of the Yatuhai lake will also be fenced off, preventing some tourists and herders from entering. We have also signed relevant agreements with the local government, and will gradually help them restore the ecological environment here, and cover the bare sand and gravel here with genetically modified desert drought-tolerant plants in a few years.
