As the large-scale data antenna system on the lunar surface was set up, Wu Hao led Zhang Jun and the others to reappear in the Xinyuehu Space Command and Control Hall.

Seeing their arrival, Yu Chengwu and Zhou Xiangming greeted them enthusiastically.

After a few pleasantries, Wu Hao then looked at the screen and said, "Let's get started."

Okay, Yu Chengwu nodded when he heard this and then ordered: "Retrieve all the images from the surveillance cameras on the lunar surface from 01 to 10 at the research station."

"clear!"

Immediately, the data screen on the big screen disappeared, and ten surveillance video screen windows appeared tiled on the big screen. The images in these video screen windows are all similar. They are all desolate moon surfaces and black cosmic backgrounds. In some of them, the earth can be seen hanging in mid-air.

"Why do I see that several scenes are repeated?" Zhang Jun observed it and then asked curiously.

Hearing Zhang Jun's inquiry, Yu Chengwu smiled and looked at Zhou Xiangming, who immediately replied: "These are ten surveillance cameras, all deployed on large data antennas.

According to different angle and position functions, it can be mainly divided into three types: wide-angle fixed machine position, rotating machine position and special machine position.

The first is the fixed position, located on the antenna mast, with a total of four at the bottom. They can cover a huge area of ​​360 degrees around the antenna, and because they use ultra-high-definition wide-angle cameras, they have strong resolution and the captured images will not be distorted.

Through these ultra-high-definition wide-angle cameras, we can realize real-time high-definition monitoring of the entire area near the lunar scientific research station, and we can also adjust the angles of these cameras as needed to achieve key monitoring.

The three cameras above are rotating cameras. They can achieve 360 ​​degrees of free rotation, monitor any angle through adjustment, and can also monitor nearby moving objects.

For example, when our intelligent control robots are working, they can achieve uninterrupted tracking and monitoring.

The three rotating cameras are all ultra-high-definition cameras that can track and monitor multiple targets at the same time. They will be our main focus in the future and will be used in the construction of scientific research stations and other scientific research projects.

Among the three cameras above, except for the top panoramic camera, the remaining two are special cameras, and an infrared spectrum camera, a synthetic aperture camera, is used to monitor infrared spectrum signals. The other one is an ultra-high-definition telephoto camera used to monitor distant areas. "

After hearing Zhou Xiangming's introduction, everyone present nodded. Zou Xiaodong, who followed Wu Hao and the others, looked at the pictures on the big screen and couldn't help but ask.

"Where is this large data antenna built? Why can't we see the lander?"

"The lander is here!" Zhou Xiangming zoomed in on a picture, pointed at the white dot in the distance and said to Zou Xiaodong. While talking, he was controlling the keyboard in his hand. As the screen continued to zoom in, everyone finally saw the full picture of the lander and the packages placed near the lander.

"How far is this lander from the antenna?" Zhang Jun couldn't help but asked curiously. Obviously, he did not expect that the antenna was so far away from the lander, and he needed to zoom in to see the lander.

The distance between the antenna and the lander is about 350 meters. With that said, Zhou Xiangming produced a lunar satellite map and introduced it to everyone.

"Everyone, please take a look. This is the satellite map of the moon near the Liffey Mountains in the northwest of Zhihai. To the west of the map is the Liffey Mountains. This is the landing site of our lander. This is the white spot.

Our antenna is established 350 meters northwest of this white spot, right here. "

At this point, Zhou Xiangming changed to a satellite map. This satellite map was the same as the previous one, except that it had many areas marked with colored boxes, lines and text.

"Everyone, please take a look, this is the satellite planning diagram of our entire lunar surface scientific research station."

"This area in the southeast on the picture, which is the dark yellow circular area, is our landing site. The entire landing site is five hundred meters in diameter. Our lander lands about ten meters in the center of the landing site, which is this white spot. .

In the northwest area of ​​the landing site, this point is our large data antenna system, and the flat area on its north side is the core area of ​​our lunar scientific research station.

This side near the Riffey Mountains is a material and equipment warehouse we built, mainly used for the storage of some materials and equipment. The area near the northwest region is one of our resource storage stations, which stores the water resources we collected, as well as liquid oxygen, liquid hydrogen and other resources obtained from electrolysis.

To the northeast of the research station is the solar power station we planned. This area will be used for the laying and installation of solar cell sail panels, and next to it will be a supporting large-scale energy storage power station to store the electricity generated by the solar power station.

To the east of the research station is the endless Zhihai Plain. We have set up an outdoor test area here to conduct some outdoor exposure experiments on the lunar surface. Find Shuyuan www.zhaoshuyuan.com ”

At this point, Zhou Xiangming changed his tone and said with a kind smile: "Of course, this is just our design and planning plan. The specific construction method must be adapted to local conditions, and some changes should be made to this planning plan according to relevant needs."

"A landing site of five hundred meters is not large in scale." Wu Hao commented after listening to Zhou Xiangming's introduction, and then said: "How do you ensure the accuracy of each landing so that the lander will land within this range? within to ensure the safety of the research station.

The second question is that the landing site is so small. How should subsequent landers land? Can it accommodate other landers? "

Upon hearing Wu Hao's inquiry, Yu Chengwu and Zhou Xiangming also put away their smiles and took it seriously.

Zhou Xiangming, who was in charge of technical aspects, explained to Wu Hao: "That's right, this landing site is just the main landing site we plan for the future landing of the ascender.

The landers currently landing on this landing site will be dismantled according to the construction needs of our research station. The parts and materials on the landers will be used in the construction of our research station to avoid related resources. Waste, this has been taken into consideration from the beginning of the design of our lunar cargo transport system lander.

As for the subsequent landing ascender, compared to this disposable lander, the control is more precise. The landing height is 14 kilometers, and the actual error is no more than 50 meters for accurate landing. Therefore, we are confident and have sufficient capabilities to ensure the safety of the lander's landing and the safety of our research station.

In addition, in order to meet subsequent needs, we will also build a larger secondary landing site outside the main landing site. It can be replaced at any time according to the needs of the task. Ensure that the safety of the research station is not compromised. "
