Half-immortal civilization

50 people and 5 scientific research vehicles embarked on the slow road of lunar exploration.

Because the master company has only now decided to build a lunar base, targeted satellites are under intense research and development, and there is still a long time before launching the moon; therefore, what everyone can rely on now is only a passion and only The five scientific research vehicles.Of course, there is a strong communication capability on it, which can directly contact the space shuttle hovering over the moon.

Because the moon's satellite has not yet come out, we can only use the space shuttle to make a guest appearance for the time being.However, the space shuttle does not have many targeted instruments and can only be used as a simple communication base station.For the time being, the connection between the moon and the ground still uses traditional radio waves, and superstring communication devices are not yet used.Anyway, it was only three to five seconds.

It's not during the war, or the time when the meteorite hits the earth, so don't care about the delay of three to five seconds.

"Expedition team, expedition team, this is the No. [-] temporary communication station. I can't see you now. Please report the location."

"Received, received. The current position is in the northern hemisphere of the moon, north of the Ocean of Storms, close to the north pole of the moon, 35° north latitude, 40° west longitude; we are going to explore in the direction of the rainy sea. According to the previous satellite image, there is a place there There may be rifts, and there is a good chance of finding a crack leading to the interior of the moon."

This time, the person in charge of the safety of these people is a recently promoted team leader in the master company: Zhou Xu; but he was also the first batch of pilots who followed Mu Xinghai to the master company, and he can be regarded as a veteran.

"Okay. No. [-] temporary communication station received it. Keep in touch. If you have any questions, you can contact at any time. The space shuttle in space will answer it nearby."

"received, thank you."

The five scientific research vehicles are not small—or they are directly converted from medium-sized trucks. You must know that on this airless moon, every breath of air needs to be carried, let alone a large number of Scientific Instruments!All daily supplies cannot be replenished on the spot; it is heavily dependent on logistics.therefore.During the expedition to the moon.These expedition teams basically need to replenish supplies every three days.After all, the most scientific research vehicles are various scientific instruments and the like; and these things consume a lot of energy.There are also 50 people's material consumption.Relying on just five cars is also somewhat insufficient.

so.The research vehicle must keep in touch with the shuttle in space at all times.certainly.This also includes first aid.In this low-gravity environment, once any physical disease breaks out, it is not a small matter.There is no 120 and no hospital here!Everything.It's all about logistics!

There is almost no sound from the motor; driving on the desolate and soft lunar surface is effortless, after all, the moon's gravity is too low.However, the surface of the moon is like a desert after all, and it is still somewhat difficult to walk forward.

"Squeak!" The vehicle braked, "Let's test it. The ripples returned by the infrasonic detector just now are not smooth." Zhang Chen monitored the screen with all his strength, and immediately discovered the change.

Speaking of it, the principle of ultrasonic or infrasonic wave detectors is relatively simple; especially in rock detection, infrasonic waves are widely used because of their relatively strong penetrating power.The principle is that the speed of sound is different in different media. According to the tracked and returned data, compared with the standard table, the composition of the material under the ground can be roughly judged.Of course, this is not accurate. Even with the latest computer technology, it is still impossible to detect objects below one centimeter. After all, this is a geological survey; and it is not a precise ray survey.

For example, the data of the propagation speed of sound in air, water, rocks, sand, metal, etc., measured at different temperatures on the ground, is made into a software and placed in the computer; when testing, it will directly return Compared with the existing data, the following composition can be roughly judged at the first time.

Of course, nature is complicated, and too many substances have similar sound propagation speeds; in this case, a real senior expert is required to judge.According to the thickness of the formation, local temperature, moisture, pressure, whether it is a seismic zone, etc., more specific information will be judged.Of course, given the complexity of nature, even Zhang Chen cannot guarantee 100% that his conclusion is correct.

"Turn on the seismic wave generator, and turn on all the detection instruments!" Professionally, Zhang Chen is meticulous.

Several assistants next to him were nervously busy: "The seismic wave generator is turned on, and the detection is normal."

On the other side, different experts are in charge of different detection instruments, and a comprehensive comparison of various detection instruments can give the most accurate figures.It's a space age, but it's also a digital age!On the ground, virtual reality 3D games have become popular—well, they are still somewhat primitive.

"Start the seismic wave generator, start all the detection instruments, and turn on the power!" At this moment, Zhang Chen is the god king who controls the technology, serious and majestic.Science cannot be sloppy!
In fact, the so-called seismic wave generator is not mysterious. It is a special hydraulic device with a steel impact head in front.Driven by the motor of the car, the two-meter-long hard steel impact head is slowly pressed into the ground until it cannot be inserted. At this time, it has been pressed into the ground to a depth of 1.2 meters.Then, under the hydraulic vibration, the steel impact head continuously hits the ground at a predetermined impact speed.From three or two times in a second to hundreds of times in a second.

This technique is simple, but the requirements for steel are extremely strict.In hard rock, there are hundreds, possibly thousands, of vibrations a second that create enormous stresses.Ordinary steel is not as strong as glass at this time.

"Didi..." Electronic instruments are constantly working, and various detection instruments are constantly summarizing the returned data and sending them to the on-board computer, and then all the data form a three-dimensional model and superimpose each other.

Different detection instruments form three-dimensional graphics of different colors; and these graphics can restore almost [-]% of the color of the object by superimposing the three primary color technology, which is almost the same as direct observation with the naked eye; the difference is only that one is direct observation and the other is through Screen indirect observation.

This seemingly simple technology is the crystallization of years of exploration by Zhang Chen and his friends!In the underground where there is no light at all, the restored colors made by using technologies such as ripples and rays stunned the boys who were exposed to these high-tech for the first time.If this kind of technology is more powerful, it will be the legendary see-through eye!When Zhang Jingyuan heard the news, he just said with emotion: technology or practice, which one is the shortcut?

Little by little, as the seismic wave generator continued to work, the three-dimensional model on the computer screen continued to enrich.Soon, a complete perspective view of the earth was presented on the screen.Such a three-dimensional figure includes a detailed hemispherical geological map with a depth of about one kilometer and a diameter of one kilometer.Even finger-sized gravel is clearly visible inside; of course, finer gravel is beyond the working range of this detector; but this is enough.I don't know, I thought it was taken with a camera!In fact, this is the result of the fusion of multiple technologies and intelligent post-processing, an rendering that is close to [-]% of realistic colors!
"This is, a hole!" Zhou Xu pointed to the edge of the rendering in surprise, and a curved "crack" appeared in one place; the hemisphere brushed against the detection range.

"Yes, this is an underground crack! It's also what we're looking for!" Zhang Chen's eyes sparkled with surprise.Unexpectedly, the target was discovered within a week of departure.But from this point of view, the interior of the moon may also be full of such cracks.Geological surveys believe in luck, but they should believe that a certain terrain is not accidental, but a widespread phenomenon.Of course, the specifics need to be verified later.
