I have a little black hole

While listening to Zhang Hanxiu's introduction, Lei Tiantang looked at the simulation test screen of the origin and found that this space garbage processor seemed to look really good.

"Is the capture net strong enough? I don't think the thickness of the net is too thick?" Lei Tiantang asked after pointing at the capture net in the projection for a while.

"We can calculate the thickness enough. Although it looks like this net is very normal, and the thickness is indeed only 0.5 cm, it has 1500 layers!

Because our capture net is woven using the latest carbon nanotube technology provided by the material company, its strength is very large. At the same time, because the density of our weave is also very dense, the mesh is also small enough, so our The space trash processor can clean up space trash with a minimum diameter of 0.5 cm. This design has fully met the boss's requirements!

According to the data of the capture network that we actually tested, even if it is impacted at a speed of 2000 meters per second, the capture network will not be broken, so there is no need to worry that it will go wrong during work.Zhang Hanxiu explained.

Lei Tiantang nodded, then fumbled his chin and said, "I have basically no problem with your design. The first-generation design can use this.

However, it would be better if a parachute system could be added to this space junk processor. I think that although these space junk seem to be garbage, it does not mean that they are worthless.

For example, satellites that cannot be used due to unexpected failures, etc., are of great value in themselves. If such satellites are recovered, we can’t use them ourselves, but we can sell them, although we can’t make much money, but this There is no shortage of fun.

You see, if the satellite's country is not willing to spend money to buy these satellites back, then we can sell them to their hostile countries. We don't care about some of the data and design ideas in the satellite, but some of this kind of things are people's concern. Right?

And I think those satellites launched around the 1960s are also a valuable asset after being recovered. It is not that their materials are valuable, but that 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 manufacture spaceships in the future.

To know that our future spacecraft will fly in space for dozens of hundreds of years or even sail to other galaxies. With our current technology, it is possible for thousands of years. For such a long time, the outer shell of the spacecraft has internal parts. Whether it can cope with such long-term corrosion is a matter to be considered.

We have a little more data in this area, and we will be more confident in the design of future spacecraft. I said so, do you understand?"

Lei Tiantang said that Zhang Hanxiu still has nothing to understand. The previous recycling of abandoned satellites is a trivial matter. At most, they can have some fun. This matter can be done. The company is taking the initiative anyway. No matter how you want to operate.

As for what other precious metals such as gold and platinum are used to make other aerospace wastes, these things are not only despised by the boss, even by him.

Even if all the 8,000 tons of space junk in Earth orbit can be recovered, the precious metals extracted from it will not be worth much. Know that his total income last year was nearly 80 million yuan, and this year should be even more. More, the company is not so bad at this point, so this is really not worth considering.

They are high-tech companies. It's okay to have some fun in recycling garbage. It really makes them solid to collect garbage, even if it is space garbage, which is a tall garbage, he is not willing to do it.

But the boss said that the space junk that has been floating in the earth's orbit for decades has been a treasure. He really recognizes it. The boss has never said that he has never thought about it.

To know that corrosion is a common phenomenon in people's daily life, whether it is metal or wood products, with time, they are inseparable from the fate of being corroded, even if it is a plastic product that is difficult to degrade in nature, It will also be slowly eroded under the "nibbling" of microorganisms.

The corrosion of metal objects is mainly reflected in chemical reactions, such as iron will rust a little bit under the action of water and oxygen, but this kind of situation is not limited to the earth.

Even in the absence of water and air in outer space, whether it is metal or other materials, they will be corroded, and the situation is far more serious than the earth, so what caused this phenomenon?Scientists believe that the following three substances are "eating" the spacecraft.

The first is radiation.Radiation is almost ubiquitous in the universe. It includes not only the energy left by the universe after the Big Bang, but also the high-energy radiation emitted by the major objects during the collision or the formation of supernovae. The living sun 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 Sunlight continues to glow and heat through the earth.

The second substance is the oxygen we are most often exposed to in daily life.Oxygen is ubiquitous on earth, but as soon as it reaches the vacuum environment 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 of the earth’s low-orbit area, where the oxygen content exceeds 80%.Under the action of high temperature, the surface material of the spacecraft rich in oxygen atoms oxidized, which caused corrosion.

The last one is temperature.Since the Big Bang, the temperature of space has been continuously decreasing. Today’s space temperature has been as low as minus 270.3 degrees, and the extreme temperature environment will affect the strain force of the spacecraft material, which makes the spacecraft material brittle and aging. It even fell off.

And materials that have been corroded by radiation, temperature, and other environments in space for decades have been really valuable to the company, because the data they carry is really a precious resource for the company. !
