"Teacher, we have determined that this crack is 832 meters deep, 1.2 meters wide and two meters high; the measured length is 33 meters.
The surrounding materials are mainly rocks, which contain abundant iron particles and a small amount of copper particles. The rock composition is mainly basalt and breccia, with a very small amount of sedimentary rock.
The metal content of surface sand and gravel is 17%; the metal content of deep layers is 19%, showing a steady increasing trend. It is estimated that there is a huge metal core inside the moon!
There are no earthquake faults, but there are rock faults. The geology is relatively stable. Given the moon's low gravity, essentially no change will occur. ”
The professional names kept scrolling, and the geologists were discussing with each other. Zhou Xu and his team members could only stare. Fortunately, I finally knew that this was a strong and stable crack. The final result of the discussion was to explore the crack carefully to see if it had actual use value.
The scientific research vehicle advanced along the crack, and the seismic wave generator continued to work. In just three hours, it consumed 30% of the energy of a vehicle.
But three hours of hard work paid off with wonderful results. This is a crack that slowly extends underground, and as the depth increases, the overall trend shows a slight increase. The surrounding area is not smooth, it can even be said to be uneven; after all, it may be a lava cave, not a man-made cave.
The section that has been detected is more than 700 meters long, and the shallowest part is more than 200 meters deep from the ground, filled with a large amount of sediment, and the bottom has some characteristics of sedimentary rocks; the deepest part is more than 1,000 meters. It also exceeds the capabilities of detection instruments.
More than two hundred meters! ! !
Seeing this data, Zhang Chen and his friends began to frown. This is not the earth. If it were on the earth, with the current technology, let alone more than 200 meters, it could still be more than 2,000 meters! The deepest oil well is over 10,000 meters - 10 kilometers!
But here is the moon, and we have five scientific research vehicles. Although they carry many instruments, a pit of more than ten meters is no problem; but a pit of more than 200 meters is beyond our reach! A clever woman cannot make a meal without rice. Scientists are not gods either!
For a while. These old experts debated endlessly; some people suggested digging here, isn't it just 200 meters! But more people suggested that by searching separately, you can always find shallower caves. But here comes a question - are you sure you can find it down there? And find it quickly? Don't forget. We are not rich in supplies. A space shuttle delivery is required every three days. Even the current detection consumption. It is estimated that it can only be supported for two days!
When doing anything in space, you have to consider the cost!
In fact, everyone also understands that this underground cave can be discovered. There is definitely a lot of luck involved; but the depth of 200 meters is a bit painful! On the earth, construction machinery can be built without any hassle in three or two days; but on the moon, you can’t even find decent tools! You can't say, Boss Zhang, we need to dig a cave and bring in a construction machine!
People don’t know yet whether they are willing to pay attention to you! God knows how much it would cost to send a machine capable of drilling a hole 200 meters from the earth to the moon!
"First make a mark, and we will explore the surrounding area for three to five days." Zhang Chen finally made the decision. In any case, a depth of 200 meters is not an easy task for the current geological expedition team.
Next to him, Zhou Xu opened his mouth, but finally said nothing; let these experts examine it first. In fact, Zhou Xu wanted to say that we have rail guns. Who says you need construction machinery to dig holes? After the rail gun is fired, the soil here will be crushed, and then digging will be much easier. Of course, rail guns also have certain dangers, what if the cave collapses!
Therefore, Zhou Xu opened his mouth in the end, but still did not speak; he was going to see how the next inspection went. It would be better if we could find shallow caves.
But what happened next was not ideal; that kind of cracks are indeed common, but most of them are in the ground below 300 meters, because the openings on the ground have been filled with sand from the lunar surface. Got it! The surface of the moon is constantly being impacted, resulting in the emergence of large amounts of sediment. The slow flow of this sediment during vibrations and the flow caused by the earth's gravity will eventually submerge all these caves.
In three days, 7 underground caves were discovered, but the shallowest one was 170 meters deep; and this underground cave was narrow.
"Go back to the original place!" Zhang Chen frowned; although no one could see the other's face clearly through the reflective mask, the voice could still be heard. Obviously, this expert, who is said to be one of the top fifty experts in the world, and a large number of top experts, are all at a loss to deal with the situation in front of them. Without tools, everything is in vain.
At this time, Zhou Xu finally had to speak. If he waits any longer, the materials consumed by the master company will be terrible; "Well, Professor Zhang, in fact, we don't have to dig, we can still destroy it!"
"Destruction?"
"Yes, you see, Gaoshou Company has a powerful electromagnetic rail gun. We can launch the rail gun from space and penetrate the ground."
"This is a good idea," Zhang Chen was not angry - why didn't you say it earlier? Instead, he asked thoughtfully: "But will this cause the ground to collapse? Bury the cave?"
"It is possible. But now a total of 8 caves have been discovered. If one of them is unsuccessful, we can just find the next one; now it seems that there are not many such caves on the moon."
"Okay, let's try the first one first. It would be better if it succeeds in one go." After thinking about it, Zhang Chen still did not reject the suggestion. First of all, everyone really has no choice; and as Zhou Xu said, there are many such caves anyway, as long as one can succeed, it is enough!
If you want to dig up hundreds of meters of crust on the ground, ordinary electromagnetic rail guns are not enough. This requires the use of large rail guns on the Rise aircraft; however, the master company's management of large rail guns is very strict and requires high-level authorization to decode. . However, Zhang Jingyuan nodded directly to this plan, which did not cause any trouble. Maybe for Zhang Jingyuan, he has already paid so much, so he won't care about more!
In addition, because of the shooting experience of Ceres and Mars, the master company is not completely violent shooting, but a design with a certain angle: about 45° to the ground, and the direction is opposite to the direction of the cave. In this case, the aftermath of the vibration will The impact on the cave will be minimized, and more importantly, after such a shooting, the trouble of later excavation will be saved! A large amount of gravel, etc., will be thrown out by the impact of the rail gun's projectiles.
"Back off, back off, 10 kilometers back!" The rail gun shooting is terrifying, especially the rail gun on the Rise, which is definitely a representative product of destruction. In space, the huge Uprising space shuttle slowly floated, entered the short and stable orbit of the moon, and then slowly changed direction. From the surface of the moon, a silver-white ghost is slowly floating in the sky! (To be continued...)
