Vol 2 Chapter 845: Space junk is also valuable!

While listening to Zhang Hanxiu's introduction, Lei Tiantang looked at the original simulation test screen, and found that this space garbage processor seemed to look really good.
"Is this capturing net strong enough? I don't think the thickness of the net is very thick?" Lei Tiantang asked after observing for a while, pointing to the capturing net in the projection.
"We calculated the thickness is enough. Although it looks like this net looks very ordinary, and the thickness is indeed only 0.5 cm, but it has 1500 layers!
Because our capture net is woven with the latest carbon nanotube technology provided by the material company, its strength is very high, and because the density of our weave is also very dense, and the mesh is small enough, our The space waste disposer can clean up space waste with a minimum diameter of 0.5 cm. This design has fully met the boss's requirements!
According to the data of the capture net we have actually tested, even under the impact of 2000 meters per second, the capture net will not be pierced, so there is no need to worry about it having problems when it is working. "Zhang Hanxiu explained.
Lei Tiantang nodded, and then groped his chin and said, "I saw that there is basically no problem with your design. The first-generation design is perfectly fine.
However, it would be better if you could add a parachute system to this space waste processor. I think, although these space wastes look like rubbish, it does not mean that they are all worthless.
For example, those satellites that cannot be used due to accidental failures, etc., are very valuable in themselves. If such satellites are retrieved, we will not need them by ourselves, but we can sell them. Although they don’t make much money, they are valuable. It's not a lot of fun at all.
You see, if the satellite’s country is unwilling to spend money to buy these satellites back, then we can sell them to their hostile countries. We don’t care about some data and design ideas in the satellites, but some people care about this kind of things. Right?
And I think those satellites launched in the 1960s are also a valuable asset after they are recovered. It is not that their materials are valuable, but we can intuitively see various metal materials and other types from them. The corrosion effect of the material in the space environment.
The corrosion effect in this natural environment is definitely different from the space environment we simulated in the laboratory, and these data will be very helpful for our company to build spacecraft in the future.
We need to know that our future spacecraft will fly in space for dozens of hundreds of years or even travel to other galaxies. With our current technology, it is possible for thousands of years. For such a long time, the outer shell and internal parts of the spacecraft Whether it can cope with corrosion for such a long time is a matter of consideration.
If we have more data in this area, we will be more confident in the design of future spacecraft. Do you understand what I said? "
Lei Tiantang said that Zhang Hanxiu still has nothing to understand. The recycling of abandoned satellites in the front is a trivial matter, and at most it is fun. This matter can be done, anyway, the company is taking the initiative. No matter how you want to operate.
As for other aerospace wastes that are made of precious metals such as gold and platinum, not only the boss looks down on these things, but he also looks down on them.
Even if all the 8,000 tons of space junk in the orbit of the earth can be recovered, the precious metals extracted are not worth much. You must know that his total income last year was nearly 80 million yuan, and it should be more this year. Many, the company is not short of money, so this aspect is really not worth considering.
They are high-tech companies. It's okay to have some fun in recycling garbage. It really allows them to collect garbage in a solid manner, even if it is space garbage, he is unwilling to do it.
However, the boss said that the space junk that has been floating in the orbit of the earth for decades is a treasure. He really agrees. If the boss said that he hadn't thought about it.
We must know that corrosion is a common phenomenon in people's daily life. Whether it is metal or wood products, they are inseparable from the fate of being corroded over time. Even plastic products that are difficult to degrade in nature. It will also be slowly eroded away under the "grabbing" of microorganisms.
The corrosion of metal objects is mainly reflected in chemical reactions, for example, iron will rust little by little under the action of water and oxygen, but this kind of situation is not limited to the earth.
Even when there is no water and air in outer space, metals or other materials will be corroded, and the situation is far more serious than that of the earth. So, what causes this kind of phenomenon? Scientists believe that the following three substances are "gnawing" on the spacecraft~EbookFREE.me~ The first is radiation. Radiation is almost ubiquitous in the universe. It includes not only the residual energy in the universe after the Big Bang, but also the high-energy radiation emitted by major celestial bodies in the process of colliding with each other or the formation of supernovae. The sun that makes a living also radiates powerful radiant energy to the earth at all times.
It is worth mentioning that the reason why organisms living on the earth are not adversely affected by radiation is mainly because the earth has a thick atmosphere. This layer of material not only ensures that the human body will not be harmed by radiation, but also allows The sun's rays continue to glow and heat through the earth.
The second substance is the oxygen that we most often come into contact with in our daily lives. Oxygen is ubiquitous on the earth, but once it reaches the vacuum of outer space, oxygen disappears without a trace.
The reason why the spacecraft is subject to oxidation is mainly because when it is launched on the earth, it first contacts the environment in the low-orbit region of the earth, where the oxygen content exceeds 80%. Under the action of high temperature, the surface material of the spacecraft rich in oxygen atoms undergoes oxidation, which leads to corrosion.
The last one is temperature. Since the Big Bang, the temperature of space has been continuously decreasing. Today, the temperature of space is as low as minus 270.3 degrees, and the extreme temperature environment will affect the strain force of spacecraft materials, thereby making the spacecraft materials brittle and aging. Even fall off.
And those materials that have been corroded by radiation, temperature and other environments in space for decades are really valuable to the company, because the data they carry is really a valuable resource for the company !
