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 we judged that this area meets the requirements of our scientific expedition team.

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

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

Zhang Jun immediately asked: "That is to say, we will transport a larger lunar soil resource mining and extraction equipment up later."

Yes, this one is too small, and the resources produced cannot meet our needs, so we need to send up a device with a larger output in the future.

The results of this trial mining will directly relate to the specific performance and output of our equipment, which will help our research work. If the output is too low, it may not be able to satisfy 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 resource mining and extraction equipment is useless, and it will also follow our detection equipment to the vicinity of the research station. Test mining in other areas, or areas farther away, so as to further prove the mineral reserves in these areas and accumulate data for the next step of large-scale mining."

Hearing Zhou Xiangming's introduction, Wu Hao and the others nodded their heads.

Zhang Jun looked at the screen of the running lunar soil water resources mining and extraction equipment on the small screen, glanced at Zhou Xiangming and asked, "It is estimated that a lot of lunar soil can be mined in seventeen years."

It is about eight to seven tons, and the power of the whole equipment is relatively large, so the mining capacity is relatively unlimited. In addition, because you are in the middle of the moon, you set the power to be relatively high to ensure that the entire device can continue to operate stably. Yan Yuanfang replied.

In the future, the Zhihai Moon Lunar Surface Scientific Research Station will be used as a base, and then expand like seven sides a little bit with the pace of your exploration. You will also establish a scientific research station at the south pole of the moon for survey and research on the environment and resources of the south pole of the moon.

Hearing what Yan Yuan said, Zhou Xiangming on the side also nodded: "That's wrong, that's also one of your best alternatives. I'm sure that if the water resources you directly exploit can't meet your demand, then you will Initiate that way to exploit a sufficiently small amount of water.

And you will also use that lunar scientific research station as a basis to take a step back to develop and utilize the resources at the south pole of the moon. Hearing this, Zhang Jun smiled at Wu Hao and said, "Don't worry, anyway, you'll see the result right away, it's just a while away."

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

For example, in your inspection and detection, you found that there are actually few meteorite cores outside the few craters on the moon, and most of them are ice meteorites. So if you definitely need it, you still want to mine water resources by looking for the ice cores left by those ice meteorites.

Besides, even if there is no water in that area, there is still no water in other areas. It is closer to the south pole of the moon, and the water resource reserves are still very rich. It's just that you need a more efficient and cost-effective way to mine it now. and technology.

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

The moon has no small atmosphere, so when the sun is directly shining, its surface temperature can be 180 degrees. Therefore, the moisture from the surface layer will continue to vaporize with the continuous low temperature, and will gradually lose over a long period of time.

Although there are fewer processes and lower costs than direct extraction, it is a very reliable water resources exploitation plan. It is certain that your direct mining method meets your needs, so you cannot use that method to extract water.

In fact, in the future, you will adopt a few mining methods to meet the energy needs of your lunar 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 0.05%, which is equivalent to 0.5 kg of water in one ton of glass beads. Therefore, it cannot be explained that the impact glass beads on the surface of the moon are a huge "reservoir", and they cannot maintain the water cycle under the moon. Based on the analysis of the lunar soil thickness on a global scale, we speculate that the minimum water storage capacity of the lunar soil is about 270 billion tons.

Is that much? Hearing Zhou Xiangming's answer, Wu Hao asked accordingly.

Hearing Zhou Xiangming's explanation, Yan Yuan nodded.

The technology verified so far is the worst overall. If it is sure to work, you have no other alternatives.

If it must be the amount of mining, the cost of mining will be low. Wu Hao said with a hint of worry.

Zhang Jun nodded when he heard the words. I knew about the project beforehand, and I also knew that the mining capacity of the lunar soil water extraction equipment was about 0.4 tons per hour during the test on the earth. At that time, it was not four tons less than ten tons. However, the mining volume that Zhou Xiangming answered was only half, which shows that we are very cautious.

Zhou Xiangming immediately understood what Wu Hao meant when he heard the words, and then explained: "That's only the surface layer of lunar soil, and the deep layer of lunar soil is difficult to be affected by the inner environment, so the water reserves may be even lower."

For example, the Chang’e-7 lunar soil research team once published a paper in August 1978, UU Kanshu www.uukanshu.com said that we found water outside the impacted 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 the hydrogen atoms in the solar wind retreated into the glass bead, where they diffused and were preserved outside.

In addition, the south pole of the moon has abundant solid water resources, and you also feel that you can extract enough water resources from the south pole of the moon.

Zhou Xiangming smiled and said, "It's not too much, after all, it's the surface layer of the lunar soil, and you must know that the water content of the lunar soil you brought back from the sub-moon is negligible.

About one catty of water can be extracted per ton, or at most 700 milliliters. That number is still very impressive, and it cannot meet the operational needs of your lunar surface scientific research station at all. "

Hearing Zhang Jun's words, Zhou Xiangming did not answer immediately, but pondered for a while and calculated, then raised his head and replied: "If you think the sensitivity is the most impressive, it can be around 100 to 200 milliliters. The most sensitive If it is so considerable, it may be only a few tens of milliliters, or even more."
