Chapter 434 Entering the Moon Underground World 2


The moon does not have a synchronous orbit; in fact, the moon's synchronous orbit has entered the gravitational range of the earth and will be pulled into an earth satellite. It seems that having a powerful neighbor is not very comfortable.

"Report to the Rising aircraft that the expedition team has arrived at the designated safe location. Zhou Xu reports!"

"Received, please make a record. All the shooting data this time needs to be collected." The pilot's voice came from the Rise.

"Understood!"

Zhang Chen and others took out instruments and prepared to record the data of this shooting. Every data collection is material for scientific development; it is also the basis for calculations for the next shooting. Science is accumulated bit by bit.

"Attention everyone, the countdown begins now. 59 seconds, 58..."

The electronic sound of the countdown sounded in everyone's headsets; a tense atmosphere began to spread. In space, every action carries a certain degree of danger.

"5, 4, 3, 2, 1, 0! Launch!"

Then I saw bright silver-white light spots in space violently shaking and retreating; this was the space shuttle that was affected by the recoil force. But there was nothing in the dark space of the moon.

Of course, no one would be foolish enough to ask. High-speed flying projectiles cannot be caught by the human eye. Moreover, it also takes a certain amount of time for the projectile to land on the lunar surface from space.

After waiting for more than three minutes, there was still no change; some young geologists who were exposed to rail gun launches at close range for the first time looked at the surrounding experts' company personnel with some suspicion: Did the launch fail? Deflected?

"Okay, okay. Don't think too much, bullets take time to fly! Even light needs time to fly!" Of course Zhou Xu had to explain to these curious babies: According to the boss's urine, these people probably escaped Without the Tathagata Buddha’s Wuzhi Mountain, in the future everyone will basically be colleagues.

After more than five minutes, a plume of smoke and dust suddenly burst out in front of them. Even if they were ten kilometers away, they could still see the smoke and dust rising violently into the sky, at least several hundred meters high. The entire smoke appears in the shape of a long strip, extending forward; the first one is very high and sparse; the later one is shorter. But there is more sediment. Almost blocking out the sun.

Rumble... It was only at this moment that the dull roar of the earth was transmitted into the space suit through the feet, allowing the team members here to hear the shallow groan of the earth.

"Success!" Some young people have begun to cheer. Just drive forward.

"Wait a minute!" Zhou Xu stopped these active young people; in fact, these so-called young people were all around 30 years old. Become a capable geologist. It takes some time to accumulate. But the environment of space makes everyone excited; especially now, seeing the collision of heaven and earth with their own eyes. Huge plumes of smoke rose into the sky, covering an area of ​​three to two kilometers! Only at this time will we have the most intuitive feeling for human technology. It is no lie to say that humans now have the ability to break the earth into pieces.

"Wait until all the dust settles before we go there." Zhang Chen was more attentive and discovered the problem immediately. There is so much smoke, dust and sediment rushing into the "sky" now, it is still very dangerous.

It took more than two hours for most of the sediment to settle in the low-gravity environment; even so, there is still a large amount of fine dust floating disorderly, some even finer, like hazy gauze, or even It is already drifting towards the outer space of the moon. Of course, the moon is not small. What can really break out of the moon is only a very small part, which can almost be ignored.

"Forward!" Zhou Xu is responsible for the safety of the team. Therefore, at a time like this, when life safety is at stake, even Zhang Chen must obey the command. Safety comes with great responsibility.

When they got closer, everyone looked at what they saw in surprise. At first, there were some inconspicuous gravels, but they had very fresh fractures, which were obviously different from the rocks on the lunar surface, and even had a certain color.

As it got closer, there were more and more rubbles, and the fragments were getting bigger and bigger. By the time they were a hundred meters away from the crater, there were already rubbles the size of a human head scattered all over. The most shocking thing is that because the projectiles were fired at a 45° angle, what appeared in front of everyone was a crater more than fifty meters long and more than twenty meters wide; the front of the crater had been impacted, Extrude a small hill with a height of ten meters. A large amount of gravel was scattered around in a radial pattern, covering a distance of several hundred meters. At first glance, this looks more like a new crater!

"Hurry up and find the underground passage, explore the passage conditions, and calculate the damage value and influence of this rail gun." Zhang Chen reacted the fastest. After taking pictures and taking samples on the spot, he immediately drove all the personnel to start working, racing against time.

It is not a simple matter to completely complete such a test work. The geological composition, crater depth, siltation depth, radiation range, vibration range, etc. all need to be measured one by one; even when necessary, a three-dimensional simulation map archive must be established.

The intense work took a full three hours; unfortunately, this time the rail gun was fired a little more carefully, and the passage with a depth of about 200 meters was not damaged - of course, this is also because the impact point is a bit far away. ; In addition, the depth of the crater is 30 meters and the depth of the projectile is 70 meters; 40 meters are caused by backfilling of quicksand and gravel in the later period.

With detailed data, calculations are faster. In just ten minutes, the supercomputer has already come up with the answer: "The calculation has been completed. The impact point should be 53 meters back, and the angle is 55°. It will be launched twice in a row."

"The Rise has been received, please everyone to move back ten kilometers!"

Returning to his previous position, Zhang Chen couldn't sit still. He stood on the roof of the car and looked into the distance, feeling silently in his heart and making calculations at the same time. I feel sad because I never thought that geological exploration, which is famous for its cautiousness, would one day need to use rail guns to open roads! If my colleagues on earth knew about it, I don’t know what kind of weird things they would say; but in this position, I feel a sense of pride and passion! However, this is indeed an effective solution and contingency measure!

At the same time, I was silently calculating in my mind; the depth of the first shot was 70 meters, and the backfill was 40 meters; and after adjusting the angle and power, the depth of the second shot was estimated to be 100 meters, and the depth of backfill should be fifty or sixty meters. meters; the following third shot, based on the second shot, should have a depth of 120 meters, and the backfill should be about 60 or 70 meters; even if the depth of the cave is not reached by then, it will not cause too much damage to the cave. influence. There is a little depth left, and the method will be decided after testing the calculations. The adjusted rail gun is more intense, and the vibration of the earth can be felt from a distance! Smoke and dust covered the sky, rushing into the sky nearly a thousand meters high. (To be continued...)
