With 50 people and 5 scientific research vehicles, we embarked on a slow road of lunar exploration.

Because the expert company has decided to establish a lunar base now, targeted satellites are under intense research and development, and it is still a long time before the launch of the moon; so what everyone can rely on now is just a passion and the only five scientific research vehicles in their hands. Of course, this has strong communication capabilities and can be directly connected to the space shuttle hovering over the moon.

Because the moon's satellite has not yet come out, we can only use the space shuttle as a guest player. 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 there is no superstring communication device. Anyway, it only takes three to five seconds.

It is not during the war, or the time when a meteorite hits the earth, so there is no need to care about the delay of three to five seconds.

"Examination Team, Expedition Team, this is the No. 3 temporary communication station. I can't see you now. Please report the location."

"Received, received. It is currently located in the northern hemisphere of the moon, north of the storm ocean, close to the direction of the north pole of the moon, 35° north latitude and 40° west longitude; we are preparing to explore the direction of the rain sea. According to the previous satellite map, there may be a rift there, and it is very possible to find a crack leading to the interior of the moon."

This time, the person in charge of these people's safety was a team leader recently promoted by the master's company: Zhou Xu; but he was also the first group of pilots who followed Mu Xinghai to the master's company, and he was also considered veterans.

"Okay, the 3 temporary communication station received it. Stay in touch. If you have any questions, you can contact us at any time. The space shuttle in space will be answered nearby."

"Received, thank you."

The five scientific expedition vehicles are not small - or directly modified from medium-sized trucks. You should know that on this moon without air, even every breath of air you breathe needs to be carried. Not to mention that there are a large number of scientific instruments! All daily supplies cannot be replenished on the spot; they rely heavily on logistics. Therefore, during the moon's inspection, these inspection teams basically need to replenish supplies every three days. After all, the most scientific expedition vehicles are various scientific instruments and the like; and these things consume a lot of energy. There is still a 50-person consumption of materials, and relying solely on five vehicles is a bit insufficient.

Therefore, the scientific expedition vehicle must be in touch with the space shuttle in space at any time. Of course, this also includes first aid. In this low gravity environment, once there is any physical disease outbreak, it is not a trivial matter. There is no 120 or hospital here! Everything is all based on logistics!

The motor has almost no sound; it is not difficult to drive on the desolate and soft moon surface. After all, the moon's gravity is too low. However, the moon's surface is like a desert after all, and it is still a bit difficult to walk forward.

"Squeak!" The vehicle brakes, "Let's test it. The ripple return of the infrasonic detector just now was not smooth." Zhang Chen tried his best to monitor the screen and discovered the changes immediately.

Speaking of which, the principle of ultrasonic or infrasonic detectors is relatively simple; especially in rock detection, infrasonic waves are more widely used because of their strong penetration. The principle is that the sound has different speeds in different media. According to the tracking and returned data, compared with standard tables, the composition of the material under the ground can be roughly judged. Of course, this is not accurate. Even if the latest computer technology is used, objects below one centimeter cannot be detected. After all, this is geological exploration; and it is not precise ray exploration.

For example, the data on the ground that is measured at different temperatures of the sound, the propagation speed of air, water, rocks, sand, metal, etc., is made into a software and placed in a computer; and during the test, the returned time distance and other data are directly compared with the existing data, so that the following composition can be roughly judged at the first time.

Of course, nature is complex, and too many substances have similar sound propagation speeds; in this case, real senior experts need to judge. More specific data will be judged based on the thickness of the strata, local temperature, moisture, pressure, whether the seismic zone, etc. Of course, given the natural complexity, even Zhang Chen cannot guarantee that his conclusion is correct.

"Open the seismic wave generator and all the detection instruments are turned on!" Zhang Chen is meticulous in his professionalism.

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

On the other hand, different experts are responsible for different detection instruments and a comprehensive comparison of various detection instruments to obtain the most accurate numbers. Although this is a space age, it is also a digital age! On the ground, virtual reality 3D games are already popular - well, and it is still a bit primitive.

"Start the seismic wave generator, start all detection instruments, and the power is fully turned on!" At this moment, Zhang Chen was the God King who controls technology, serious and majestic. Science cannot tolerate carelessness!

In fact, the so-called seismic wave generator is not mysterious. It is a special hydraulic device. In front of it is a steel impact head. Driven by a car motor, a hard steel impact head of two meters is slowly pressed into the ground until it cannot be inserted. At this time, it has been pressed into the ground at a depth of 1.2 meters. Then, under the vibration of the hydraulic pressure, the steel impact head continuously impacts the ground according to the established impact speed. From three or two times in the first minute to hundreds of times in one second.

This technology is simple, but the requirements for steel are extremely strict. In hard rocks, hundreds of vibrations in a second, or even thousands of vibrations, will produce huge stress. Ordinary steel is not stronger than 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 is formed into a three-dimensional model and superimposing them on each other.

Different detection instruments form three-dimensional figures of different colors; these figures can be superimposed by three primary color technology, which can almost restore 90% of the object's color, which is almost no different from direct observation of the naked eye; the only difference is that one is direct observation and the other is indirect observation through the screen.

This seemingly simple technology is the crystallization of years of exploration by Zhang Chen and his friends! In the underground without light, the restored colors made by using ripples, rays and other technologies were shocked by the young men who were exposed to these high-tech for the first time. If such technology is more powerful, it is the legendary perspective eye! When Zhang Jingyuan learned the news, he just sighed: Which is the shortcut, technology or practice?

Little by little, as the seismic wave generator continues to work, the three-dimensional model on the computer screen continues to enrich. Soon, a complete earth perspective is presented on the screen. Such a three-dimensional figure covers a hemispherical geological detail of a depth of about a thousand meters and a diameter of kilometers. Even the gravels of fingers are clear inside; of course, even smaller gravels, etc., exceed the working range of the detector; but this is enough. If you don’t know, you think it was taken with a camera! In fact, this is the result of a combination of multiple technologies and post-intelligent processing, a rendering of nearly 90% of the color!

"This is, a hole!" Zhou Xu pointed at the edge of the rendering in surprise, and a curved "crack" appeared in one place; it rubbed against the hemisphere of the detection range.
