Chapter 895

Therefore, the company's propaganda department used the company's media resources and technical advantages to suppress some news that was not conducive to the company, so as to ensure that the company can occupy an advantage in the field of publicity.

When the new propaganda war is in full swing on this side of the earth, Lei Tiantang and others on the lunar advance base have completed the overall tour work and are ready to start their own work. Of course, before this, they should first enter the sealed cabin of the base, which is not a simple thing!

The environment on the moon is quite different from that on the earth. It can be said that it is very dangerous. In ancient times, people filled with beautiful imagination about the moon, such as Chang'e flying to the moon, Guanghan palace, Wu Gang's expedition to GUI, etc.

However, after the real exploration of the moon, we found that the moon is not as beautiful as we think, its surface is only desolate.

It is traditionally believed that human life on the moon and other celestial bodies without air will be threatened by cosmic radiation, high-energy particles and other characteristics of outer space, such as the threat of meteorite impact.

As a satellite of the earth, the moon has been guarding the earth's side. It protects the earth from the impact of meteorites and asteroids in the universe. Therefore, we can see that there are craters all over the moon, which is visible to the naked eye.

We should know that the moon does not have an atmosphere. If astronauts and bases encounter meteorite impact, even if it is a fragment meteorite with the size of nail plate, it is also very dangerous. We can imagine the power of meteorite impact that exceeds the flying speed of bullets!

Of course, the scientists of the company will not ignore the threat that can be found at a glance. They use the high-performance protective materials developed by the materials company. After scientific design, they have added a very strong defense layer to the outer layer of the base cabin to ensure that even if the base encounters some small meteorite impact, it will not be broken down.

Of course, the specially designed spacesuit can also ensure the safety of astronauts. After all, the company has the electromagnetic railgun, which is a convenient test equipment. Of course, we can test whether the spacesuit can resist the impact of small debris meteorite.

In addition, the detection system composed of the radar installed in the base and various satellite detectors in the lunar orbit can also detect these high-speed meteorites in advance, and can give early warning before the danger is found.

Then through a set of defense system composed of electromagnetic railgun and laser weapon system to resist the impact threat of these meteorites on the base, the debris meteorites that are hard to be found and the meteorite fragments produced after defense attack are basically not too dangerous.

Therefore, the dangers on the surface can be basically eliminated, but in addition to these threats, there are also some risks that we will ignore if we do not conduct careful scientific research. This kind of risk factors from the moon itself will also bring a huge threat to the safety of astronauts and forward bases!

If man wants to conquer the moon and establish a base there, the dust of the moon is a huge obstacle in the way of conquering the moon.

In a previous study by American scientists, some pharmacologists, geneticists and earth scientists have found that exposure to lunar dust will seriously affect the health of future astronauts.

The Apollo 17 spacecraft of the United States carried three astronauts to complete the last lunar walk mission of human beings on the moon so far. After falling down several times during the investigation, the surface of the spacesuit was covered with dust. The goggles of the helmet were not smooth, and there were numerous small scratches, among which the helmet damage was particularly serious.

He even doubted whether the suit would stick to the planned extravehicular activities before returning to earth. And the astronauts lamented to the Houston command center that "I've never seen so much dust in my life.".

After returning to the lunar module, it was even difficult for the two to take off their gloves, because the dust still penetrated into the mechanical joint although the protective flap was added to the spacesuit.

After returning to earth, the two also confirmed a statement made by all astronauts since the Apollo 11 mission that one of the main problems encountered in landing on the moon is dust, which must be solved if we want to return to the moon and establish a semi permanent base.

And this problem was also discovered by the scientists of the infinite gravitation group. After their preliminary exploration and research, they also found that if this problem is not solved, it is impossible to complete the lunar colonization.

So what's the problem with this lunar dust? The first, of course, is the severe destruction of the lunar landing equipment. Although the lunar dust looks like talcum powder, it is only a surface phenomenon.

In fact, lunar dust is a kind of floating soil, mainly composed of silicified or vitrified fragments. The average diameter of these small particles is only 20 μ M. if most of the particles are less than 5 μ m, they form a few meters thick floating soil layer, which is very destructive.

We should know that the moon has no atmosphere and water, and it has not suffered any erosion for more than 4 billion years. Therefore, every particle of dust here retains its original shape, and its sharp edges and corners can be seen only under a microscope. They are comparable to the first-rate abrasives used in industrial production on earth!If astronauts stay in this environment for a few hours, these "Abrasives" may cause problems in the spacesuit and threaten the life of astronauts.

What's more, in addition to direct wear and tear, the dust will stick to the surface of the spacesuit like the nylon fastener. Even if you use a brush or vacuum cleaner to suck, you still feel helpless about these tiny particles.

In addition, there are some metal components such as iron, aluminum, titanium and so on in this kind of floating soil. Under the radiation of sunlight, these materials make these dust generate static electricity, which is easier to adsorb on the surface of various metal or plastic products, especially at the joints of gloves, helmets and hatch doors, resulting in the reduction of sealing performance of these equipment, and even cause gas leakage in serious cases.

Therefore, it is precisely because of the existence of these dust, Apollo mission equipped with space suits used on the surface of the moon more than 20 hours, there will be a great security risks, so that astronauts face a major threat.

Why should the scientists of the infinite gravitation group customize the suits suitable for the moon instead of the previous ones used in the space station? The reason is that they also found that if they want to work on the lunar base for a long time, the quality and safety of space suits must be solved!
