On the ground, a new wave of space shuttles to support the construction of the moon have taken off. Now, almost 100% of all the materials needed for the construction of the moon require ground support. Even in the early stages of construction, even power resources need to be transported from the ground.
At the same time, geologists on the moon have begun to enter the underground pits of the moon, preparing to explore the conditions inside the moon; especially Zhang Chen once promised Zhang Jingyuan to find large natural metal deposits on the moon!
The scientists carrying a large amount of supplies were like Mr. Turtles carrying huge turtle shells, bloated and inconvenient to move!
Fortunately, this underground cave is quite friendly and spacious. If you go alone, it will basically not cause too much crowding.
Everyone did not rush in all at once, but kept exploring around.
"It's no mistake, this is a lava cave, exactly the same as the one on the earth. The difference is that it contains a large amount of cooled metal elements. Look, this is copper, this is silver, this is lead, and this is zinc; according to the chromatogram Analysis shows that this is magnesium oxide and copper sulfate powder. Unfortunately, the moon is very dry. If it were on the earth, beautiful malachite would be formed!”
"Huh? Professor Zhang, didn't you say that there would be metal elements on the moon? Why would there be magnesium oxide?" Next to him, Zhou Xu had some questions.
"It's just that there are elements, but not all of them are elements. Geological activities are complex; especially metals such as magnesium are very active and can even rob oxygen ions from other oxides. But this is just the beginning, so many metals have been discovered Yes, it seems that there is indeed a natural treasure on the moon.”
"Yes, yes." Zhou Xu agreed, "I'm a rough guy and don't know much. But the leaders of the company have been emphasizing that in the space age, steel is more precious than gold. So, I also know a little. A large number of simple metals , is actually the most valuable resource. ”
"Haha, that's good! It seems that Gaoshou Company is what it is now. There is something special about it. While others are still thinking about going into space to find gold and silver, you have actually realized the importance of steel and other metals.
Walk. Go deeper. There is nothing here worthy of special attention and study. Except that it contains a large amount of metal elements and a particularly high content of metal particles, it is no different from the Earth group. They are all cooled lava caves. ”
Soft fluorescent lighting tool allows the surroundings to show the most natural and realistic colors. Such top-grade fluorescent lamps are extremely expensive, and only expert companies can have the ability and determination to do so. One for each person! The price is as high as one million yuan. This is truly top of the line equipment.
"Dangdang! Found a piece of gold!" All of a sudden. Even Zhou Xu was moved. Unexpectedly, he won the first prize.
"Throw it away!" After Zhang Chen observed it for a moment, he curled his lips disdainfully. "A piece of shit gold, the legendary copper-zinc alloy!"
"Uh... I'm so happy for nothing!" After cutting it with a knife, it was easy to tell; there were even some places inside that were unevenly blended, showing silvery white or purple-red color. But this thing also has collection value; it's not heavy anyway, so Zhou Xu threw it into his backpack.
The ground is not flat, it is just a lava cave after all; and it is even a bit narrow in some places, which is caused by the uneven cooling of the lava. But everyone can occasionally find beautiful stones here. Such as crystal, calcite, etc.
Some people will collect specimens. After all, it is not easy to go to the moon, especially Zhang Chen and others, who are not from a master company.
"Be careful, there seems to be a change on the ground ahead!" warned the person from the master company who was walking at the front.
When we got closer, we discovered that the front suddenly became much steeper, even showing a downhill slope of about 30°.
"Don't worry, it's normal. After all, volcanic lava comes from the interior of the earth's crust, and it is normal for it to go downhill. Even this slope is already very gentle." Zhang Chen is a geologist after all, so he was not surprised.
However, after everyone walked about a hundred meters again, the road became steep again; but it was not an instant change, but a gradual change. The area around the cave is becoming more and more empty, and in some places you can even see beautiful crystal clear stones, or gems; and the frequency of simple metals has also increased a lot.
Suddenly, a team member accidentally pushed a weak stone, and then it rolled down into the depths of the moon.
Rumble? ? ?
For a moment, everyone was stunned. They did not expect that there was air in the space inside the moon!
"Didi..." No air analysis instrument was prepared, but it didn't trouble the experts. Through spectral analysis, the proportion of atoms in the air can be directly measured.
"12% sulfur atoms, 42% oxygen atoms, 7% carbon atoms, 4.5% nitrogen atoms, and 11% hydrogen atoms... According to reasonable proportion distribution, the main components of air are sulfur dioxide and sulfur trioxide, carbon dioxide, and nitrogen oxides; followed by It is composed of water (steam), hydrogen molecules, methane, hydrogen sulfide and other gases, which are toxic to the human body
In addition, the density of air is approximately 0.12 kilograms per cubic meter. Only one tenth of the Earth's atmosphere. ”
"Okay, make a record." Zhang Chen nodded, and then used a high-brightness flashlight to look forward. The front began to get steeper, and even tended to develop towards a bottomless pit.
"Prepare the rope." Before Zhang Chen could speak, Zhou Xu had already directed the people in the master company to take action. High-strength carbon fiber cable, strong and lightweight. The diameter is less than 7 mm, but it can lift objects weighing three tons.
Sections of rope were spliced together, and the approximate depth below was first explored.
"Boom!" A muffled sound came, and the stone tied in front had fallen.
"Depth of 87 meters." The team member responsible for distributing ropes reported the number.
"Change the direction and continue the exploration!" Compared to Zhou Xu and others, Zhang Chen is more cautious and knows how to make the expedition safer.
88 meters, 102 meters, 79 meters, 81 meters...
Several consecutive numbers come out, so that everyone has a general understanding of the following. Zhou Xu took the risk himself, hanging himself on the rope, and using a strong flashlight to explore the terrain below while dangling in mid-air.
Zhou Xu: "The bottom is a typical terrain after the lava has cooled. There are no rocks, only a relatively smooth ground. It is quite undulating."
Zhang Chen: "Have you seen the colors clearly? Different colors represent different geological conditions and different material compositions."
Zhou Xu: "I can't see clearly. There seems to be reflection like water in some places. I don't know if it's an illusion."
"It shouldn't be! The interior of the moon should be very dry. It may be fragments of calcite or crystal and other transparent rocks." Zhang Chen's tone was almost certain.
"Oh, yes, it's not like water, because there is no change at all. If anyone is convenient, throw a few stones and let me see how the ground is."
Bump... Several rocks exploded on the ground.
"The ground is very solid, there should be no danger. I'll go down first and wait for my news!" Zhou Xu slid down slowly along the rope, constantly observing the rock wall along the way. As we go deeper, there are more and more metal particles on the rock wall, and there are even large amounts of metal blocks gathered in some places. (To be continued...)
