50 people and 5 scientific research vehicles embarked on the slow road of lunar exploration.
Because the Gaoshou Company has just decided to build a lunar base, targeted satellites are under intense research and development, and there is still a long time before launching to the moon; therefore, what everyone can rely on now is only their passion and what they have. of five scientific research vehicles. Of course, it has powerful communication capabilities and can directly contact the space shuttle hovering over the moon.
Because the moon's satellite has not yet come out, the space shuttle can only make a cameo 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 no superstring communication devices are used. Anyway, it’s only three to five seconds.
It's not during a war, or when a meteorite hits the earth, so there is no need to care about the three to five second delay.
"Expedition team, expedition team, this is temporary communication station No. 3. I can't see you now. Please report the location."
"Received, received. The current location is in the northern hemisphere of the moon, north of Oceanus Procellarum, close to the north latitude of the moon, 35° north latitude, 40° west longitude; we are going to explore in the direction of Mare Imbrium. According to previous satellite images, there is a place there There may be rifts, and there is a high possibility of finding cracks leading to the interior of the moon.”
This time, the person responsible for the safety of these people is Zhou Xu, a recently promoted squad leader in the Gaoshou Company. He is also the first batch of pilots who followed Mu Xinghai to the Gaoshou Company, and can be regarded as a veteran figure.
"Okay. Temporary Communication Station No. 3 received it. Keep in touch. If you have any questions, you can contact us at any time. The space shuttle in space will answer the call nearby."
"Roger that, thank you."
The five scientific research vehicles are not small - or they are directly modified from medium-sized trucks. You must know that on this airless moon, every breath of air needs to be carried, not to mention a large amount of Scientific instruments! All daily supplies cannot be replenished on site; it relies heavily on logistics. therefore. During the lunar expedition. These inspection teams basically need to replenish supplies every three days. After all, the largest number of scientific research vehicles are various scientific instruments, and these things consume a lot of energy. There is also material consumption for 50 people. Relying on just five vehicles is also somewhat inadequate.
so. The research vehicle must maintain contact with the space 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 trivial matter. There is no 120 or hospital here! All in all. It all depends on logistics!
The motor makes almost no sound; 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 difficult to move forward on foot.
"Squeak!" The vehicle braked. "Let's test it. The ripples returned by the infrasound detector just now were not smooth." Zhang Chen monitored the screen with all his strength and noticed the change immediately.
Speaking of which, the principle of ultrasonic or infrasonic detectors is relatively simple; especially in rock detection, infrasound waves have many applications because of their relatively strong penetrating power. The principle is that sound has different speeds in different media. Based on the tracking and returned data and comparing it with the standard table, the material composition under the ground can be roughly judged. Of course, this is not accurate. Even with the latest computer technology, it is still unable to detect objects below one centimeter. After all, this is a geological survey; and it is not a precise radiographic survey.
For example, data on the propagation speed of sound in air, water, rocks, sand, metal, etc. measured on the ground at different temperatures are made into a software and placed in the computer; during testing, the data returned directly time distance, etc., and by comparing it with the existing data, the following composition can be roughly judged at the first time.
Of course, nature is complex, and there are too many substances with similar sound propagation speeds; in this case, real experts are needed to judge. More specific data will be determined based on the thickness of the formation, local temperature, moisture, pressure, whether it is an earthquake zone, etc. 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 detection instruments!" Professionally, Zhang Chen is meticulous.
Several assistants nearby were busy nervously: "The seismic wave generator is turned on and the detection is normal."
On the other side, different experts are responsible for different detection instruments. Comprehensive comparison of various detection instruments can produce the most accurate figures. Although this is a space age, it is also a digital age! On the ground, virtual reality 3D games have become very popular - well, they are still a bit primitive.
"Start the seismic wave generator, start all detection instruments, and turn on the power!" At this moment, Zhang Chen was the god-king who controlled technology, serious and majestic. Science has no room for sloppiness!
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 car motor, the two-meter-long hard steel impact head was slowly pressed into the ground until it could no longer be inserted. At this time, it had been pressed into the ground to a depth of 1.2 meters. Then, under the vibration of hydraulic pressure, the steel impact head continuously impacts the ground according to the established impact speed. From three or two times per minute to hundreds of times per second.
This technology is simple, but the requirements for steel are extremely strict. In hard rock, huge stresses can be generated from hundreds, perhaps even thousands, of vibrations per second. Ordinary steel is no better than glass at this time.
"Didi..." Electronic instruments are constantly working, and various detection instruments continue to summarize the returned data and send it to the on-board computer. Then all the data forms a three-dimensional model and is superimposed on each other.
Different detection instruments form three-dimensional graphics of different colors; and these graphics are superimposed using three primary color technology, which can restore almost 90% of the color of the object, which is almost the same as direct observation with the naked eye; the only difference is that one is direct observation and the other is through Screen indirect viewing.
This seems to be a simple technology, but it is the culmination of many years of exploration by Zhang Chen and his friends! The young men who came into contact with these high technologies for the first time were stunned by the restored colors produced by technologies such as ripples and rays in the underground with no light at all. If this kind of technology were more powerful, it would be the legendary clairvoyance! When Zhang Jingyuan learned the news, he just sighed: Which one is the shortcut, technology or spiritual 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 perspective view of the earth appeared on the screen. Such a three-dimensional figure includes a detailed geological map of a hemisphere with a depth of approximately one kilometer and a diameter of one kilometer. Even the finger-sized gravel inside is clearly visible; of course, smaller gravels are beyond the working range of this detector; but this is enough. For those who didn’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, a rendering that is almost 90% realistic in color!
"This is a hole!" Zhou Xu pointed in surprise at the edge of the rendering, where a crooked "crack" appeared; the hemisphere passing by the detection range. "Yes, this is an underground crack! It is also the target we are looking for!" Zhang Chen's eyes flashed with surprise. Unexpectedly, the target was discovered less than a week after setting off. However, it seems that the interior of the moon may also be full of such cracks. Geological surveys believe in luck, but we should also believe that a certain type of terrain is not accidental, but a widespread phenomenon. Of course, the specific details will need to be verified later. (To be continued...)
