Military Technology

Hearing Zhang Jun's question, Zhou Xiangming replied with a smile: "The previous exploration only gave us a general understanding of the basic situation of this area, and judged that this area meets our requirements for building a scientific expedition team.

But we still don’t know what is going on here, so we need to conduct a more detailed exploration and trial mining to find out the specific and detailed resource reserves of this area, which is very important for our next use of this area. "

After listening to Zhou Xiangming's introduction, both Zhang Jun and Wu Hao nodded involuntarily.

Zhang Jun then asked: "In other words, we will have to transport a larger lunar soil resource mining and extraction equipment later."

Yes, this machine is too small, and the resources it produces cannot meet our needs, so we need to send in a piece of equipment with a larger output in the future.

The results of this trial mining will be directly related to the specific performance and output of our equipment and will be helpful to our research work. If the output is too low, it may not be able to meet the operation of our lunar surface scientific research station, which will have an important impact on our subsequent related work.

Speaking of this, Zhou Xiangming paused for a moment, and then continued: "Of course, this does not mean that this lunar soil water resources mining and extraction equipment is useless. It will also follow our detection equipment to the vicinity of the research station. Conduct trial mining in other areas, or further away areas, to further explore the mineral reserves in these areas and accumulate data for the next large-scale mining."

After hearing Zhou Xiangming's introduction, Wu Hao and several others nodded.

Zhang Jun looked at the picture of the lunar soil water resources mining and extraction equipment in operation on the small screen, glanced at Zhou Xiangming and asked: "How much lunar soil is expected to be mined in seventeen days."

It is about eight to seven tons. The entire equipment is relatively powerful, so the mining capacity is relatively unlimited. In addition, because we are on the moon, you set the power to a relatively high level to ensure that the entire device can continue to operate stably. Yan Yuanfang replied.

In the future, the Zhihai Lunar Lunar Surface Scientific Research Station will serve as a base, and then it will gradually expand to the seven sides as your exploration progresses. You will also establish a scientific research station on the lunar south pole for survey and research on the lunar south pole environment and resources.

Hearing what Yan Yuan said, Zhou Xiangming on the side also nodded: "Yes, that is also one of your best alternatives. If the water resources you directly mined can meet the demand, then you will Start that way to exploit a small enough amount of water.

And you will also take a step back to develop and utilize the moon's Antarctic resources based on the lunar scientific research station. Hearing this, Zhang Jun smiled at Wu Hao and said, "Don't worry, you'll see the results right away anyway. It's just a short time away."

So how much water does he think can be extracted from eight to seven tons of lunar soil?

For example, during your patrols and detections, you found that there are actually very few meteorite cores outside the few craters on the moon, and most of them are ice meteorites. So if necessary, you can still mine water resources by looking for the ice cores left behind by ice meteorites.

Besides, even if there is no water in that area, there is still no water in other areas. There are still very abundant water resources closer to the south pole of the moon, but now you need a more sensible and cost-effective way to exploit them. Just technology.

The outer dimension is relatively low, and it is far away from the Waifei Mountains, so some water resources will be retained on the surface. "

The moon has a small atmosphere, so when the sun shines directly on it, its surface temperature can reach 180 degrees. Therefore, the moisture on the surface will continue to evaporate with the low temperature and gradually lose over a long period of time.

Although it requires fewer processes and lower costs than direct extraction, it is a very reliable water resource extraction solution. Make sure your direct mining method meets your needs, so you can't use that method to extract water.

In reality, you will adopt several mining methods in the future to meet the energy needs of your lunar surface scientific research station.

Of course, the water we are talking about is not the liquid water you usually talk about, but exists outside the glass beads in the form of hydrogen atoms. It needs to be converted into water that you can use most through chemical reactions.

We say that the average water content in glass beads reaches up to 0.05%, which is equivalent to 0.5 kilograms of water in one ton of glass beads. This does not mean that the impact glass beads on the lunar surface are a huge "reservoir" and they cannot maintain the water cycle under the moon. Based on the analysis of the moon's global-scale lunar soil thickness, we infer that the minimum water storage capacity of the lunar soil is about 270 billion tons.

So much? After hearing Zhou Xiangming's answer, Wu Hao asked.

After hearing Zhou Xiangming's explanation, Yan Yuan nodded.

The technology that has been verified so far is the worst overall. If it is definitely feasible, you don’t have any other alternatives.

If the mining volume is definitely that, the mining cost will be low. Wu Hao said with a hint of worry.

Zhang Jun nodded when he heard this. I had learned about the project beforehand, and also knew that the lunar soil water resources mining and extraction equipment mined about 0.4 tons per hour when tested on Earth. Seventeen tons per hour. At that time, it was not four tons less, but ten tons slower. The mining volume that Zhou Xiangming answered is only less than half. It can be seen that we are very cautious.

Zhou Xiangming immediately understood what Wu Hao meant when he heard this, and then explained: "That is only the surface lunar soil. The deep lunar soil is difficult to be affected by the environment inside, so the water reserve may be even lower."

For example, the Chang'e-7 lunar soil research team published a paper in August 2078, saying that we found moisture outside the impact glass beads in the lunar samples of Chang'e-7. The researchers measured the water content in the center and edge of the glass beads and found that the water content in the glass beads gradually decreased from the edge to the center. We reasoned that this was because hydrogen atoms in the solar wind retreated into the glass bead, where they were diffused and preserved outside.

In addition, the South Pole of the Moon has abundant reserves of solid water resources, and we also feel that it is difficult to exploit enough water resources from the South Pole of the Moon.

Zhou Xiangming smiled and said: "That's not too much. After all, it is the surface lunar soil. You must know that the water content of the lunar soil you will bring back from the samples taken from the moon is very small.

Each ton can extract approximately one kilogram of water, or up to 700 milliliters. That number is still very impressive, and it cannot meet the operational needs of your lunar surface scientific research station at all. "

After hearing Zhang Jun's words, Zhou Xiangming did not answer immediately. Instead, he pondered for a moment and calculated, then raised his head and replied: "If you think the most significant amount is around 100 to 200 milliliters." If it is so considerable, it may only be a few tens of milliliters, or even more."
