The Technology Tree of Xueba

Peng Feng led the prospecting team to dig more than 20 detection points in half a month.

They came to the depths of a larger crater on the back of the moon and continued to collect samples of the lunar crust.

Peng Feng encouraged: Hurry up, everyone, this is the last detection point. After we collect samples, we can return to the lunar advance base.

They began to collect the lunar rock formations at this detection point according to the previous procedures.

Wang Zhihua was in charge of adjusting the scale of the equipment. He thought that after his work this time, he would have completed his service plan on the moon, and he could apply to return to Earth.

Now he is debating whether he should return to Earth or still work at the Moon Advance Base.

Wang Zhihua was a little absent-minded, and set the scale of the machine directly according to the previous operation process.

Time passed slowly, and the drilling machine trembled tremendously, and soon stopped working.

When Peng Feng saw this situation, he immediately shouted: Wang Zhihua, what did you do? How could you follow the scale set last time? Last time we collected on a mountain peak, this time it was in a crater At the bottom, the difference in the thickness of the crust can be as much as 5 kilometers.

The bottom of the moon's crust is very dense and can easily damage a drilling rig.

When Wang Zhihua saw that the drilling rig was damaged, he thought it was his fault and just wanted to apologize.

Suddenly seeing the parameters of the depth of the drilling rig, he immediately retorted: Captain Peng Feng, you must have misunderstood it!

That's right, there is a height difference of 5 kilometers between the last collection point and this place based on the lunar horizon.

But what we collected were 20 kilometers of lunar crust samples, and now the drilling rig has just drilled 18.9 kilometers, which has not reached the scheduled 20 kilometers at all.

Our depth reference is measured at the height of the detection ground, not the height of the lunar horizon.

Peng Feng checked the data carefully, and found that what Wang Zhihua said was correct, he said with some embarrassment: I didn't investigate carefully just now, I misunderstood you just now.

Without reaching a depth of 20 kilometers, how could the drilling rig be damaged suddenly.

As they spoke, the rest of the team had pulled the damaged rig up.

Peng Feng watched the impact, the blade made of high-density material in front had been completely polished.

After the blade was sharpened, the drill could no longer cut through the rock, causing it to get stuck in rock crevices, burning out the drill components.

Peng Feng looked at the collected rock samples of the lunar crust, and he said relaxedly: Fortunately, the crust samples were collected, and the damage to the drilling rig can be reported. Our work is completed.

On January 11, 2028, Zhou Yu was learning about the minerals of the moon at the Spark Science and Technology Research Institute.

Huang Ke is reporting the statistical results of the scientists to Zhou Yu.

Mr. Zhou, we have repeatedly explored lunar resources with advanced lunar resource exploration satellites and space shuttles.

We sent another 76 prospecting teams to sample lunar crustal rocks. Scientists have analyzed thousands of lunar crustal rock samples.

Now we have all the resources on the moon under control.

There are not many valuable minerals on the moon. Most of the elements that exist on the earth are found on the moon, but they are not enriched together to form mineral veins.

There are only 43 iron mines, 27 copper mines, 8 zinc mines, 5 silver mines, and 2 gold mines in the large veins with reserves of more than one million tons.

Because moon mining is relatively expensive, they are extremely valuable mines.

The cost of mining other veins is relatively high, it is better to send the space shuttle directly to the asteroid belt for mining.

Zhou Yu smiled and said: This is already very good, now send intelligent robots to mine these valuable ore veins, and leave the other ore veins for future generations.

When the technology matures, we can resell those veins with relatively low reserves at a good price.

Zhou Yu is very satisfied with the large mineral veins found on the moon, especially the discovery of precious metals such as large gold mines.

Gold and silver are two metals that are extremely useful in modern industry, but they are somewhat expensive.

Now they can mine and refine these metal mines with the largest reserves by themselves, which can save a lot of cost.

Mr. Zhou, our company's scientists analyzed the moon rock samples and found some strange phenomena. Huang Ke said somewhat mysteriously.

What kind of strange phenomenon is it? It is a good thing that strange phenomena appear. Cracking these phenomena may bring about some technological progress.

There are no mysteries in the world, and now we feel mysterious, but technology has not yet developed to such an extent that it cannot explain this phenomenon. Zhou Yu asked excitedly.

When the ancients saw a mobile phone playing a video, they must have thought it was a mysterious phenomenon.

If some future technologies appear on the present earth, people on earth will definitely feel that this is a mysterious phenomenon.

It is not terrible to have mysterious phenomena, what is terrible is to worship them as superstitions.

Huang Ke saw Zhou Yu's expectant eyes, and he immediately told the situation they introduced when chatting with the scientists.

Mr. Zhou, in order to detect the existence of mineral veins in the lunar crust, we dispatched multiple prospecting teams to collect many samples of the lunar crust.

The density of rock specimens brought back is far greater than that of earth rocks.

It is common for lunar rock specimens to have a high density. There are differences in their densities, but they are all denser than rocks on Earth.

The total mass of the moon will be much larger than the current calculation result, and correspondingly, its gravitational strength will also be larger.

Considering that the surface of the moon is much closer to the center of the moon than the surface of the earth is from the center of the earth, plus its total mass, the gravitational force will be much greater than we imagined.

However, the gravitational force of the moon is only one-sixth of the gravitational force on the surface. According to the gravitational force, the mass of the moon is much smaller than the mass of the moon inferred from the density of lunar rock samples.

It seems that the gravitational force of the moon has nothing to do with its density and mass.

This is of course impossible. Scientists speculate that the density distribution of the moon is extremely uneven.

Inside the lunar crust, there are many gases or cavities that can cause this phenomenon.

It's just that what causes the uneven density of the moon's crust remains to be tested in the future.

Zhou Yu heard that Huang Ke was talking about this matter, and he felt that there were not many secrets hidden in it.

Different parts of celestial bodies have different densities, which is very normal.

For example, the magma inside the earth must have a different density than the crust.

The density at the center of the sun is also very different from the density at the surface of the sun, which is a very normal phenomenon on a planet.

Even if the difference of the moon is a bit large, it is within a reasonable range.

This problem is nothing special. It's not worth our continuous tracking. I'll take a look at where the moon rock samples are placed. Zhou Yu asked.

Huang Ke replied immediately: Mr. Zhou, he is in the Astroenvironmental Laboratory. We have collected too many moon rock samples, and we plan to donate some to other scientific research institutions.

Rare things are more expensive, and now Xinghuo Technology has too many samples of moon rocks, and the value has dropped sharply.

These moon rock samples are kept in the laboratory, which costs a lot of money every day.

Huang Ke had long wanted to get rid of this hot potato, and seeing that Zhou Yu was interested in lunar rock samples, he immediately took him to the laboratory where lunar rock samples were stored.
