I Have a Little Black Hole

While listening to Zhang Hanxiu's introduction, Lei Tiantang looked at the simulation test screen of Origin, and found that the space junk disposer 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, pointing to the capturing net in the projection after observing for a while.

We calculated that the thickness is enough. Although this net seems to be very ordinary, and the thickness is indeed only 0.5 cm, it has 1,500 layers!

Because our capture net is woven with the latest carbon nanotube technology provided by the material company, it is very strong. At the same time, because the density of our weaving is also very dense and the mesh is small enough, our The space junk disposer can clean up space junk 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 that we have actually tested, even if it is hit at a speed of 2000 meters per second, the capture net will not be pierced, so there is no need to worry about it going wrong when it is working. Zhang Hanxiu explained.

Lei Tiantang nodded, then groped his chin and said, I've seen basically no problem with your design, and it's totally fine to use this design for the first generation.

However, it would be even better if a parachute system could be added to this space junk disposer. I think, although these space junk looks like junk, it does not mean that they are all worthless.

For example, those satellites that cannot be used due to unexpected failures and other reasons are very valuable in themselves. If such satellites are brought back, we will not need them, but we can sell them. The fun is not much at all.

You see, if the country to which the satellite belongs 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 data and design ideas in the satellites, but some of this kind of thing is something that people care about. Bar?

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. Corrosion effect of materials in space environment.

The corrosion effect in this natural environment is definitely different from the space environment we simulate in the laboratory, and these data will be very helpful for our company to manufacture spacecraft in the future.

We must know that our future spacecraft will fly in space for tens 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 of the spacecraft and the internal parts Whether it can cope with corrosion for such a long time is something to be considered.

If we have a little more data in this area, we will have more confidence in the design of future spaceships. Do you understand when I say this?

Lei Tiantang said what Zhang Hanxiu didn't understand. The recycling of abandoned satellites in front of them was a trivial matter. At most, it was just to have some fun. This matter can be done. Anyway, the company is taking the initiative. No matter what you want to do.

As for other aerospace wastes, they are made of precious metals such as gold and platinum, but these things are not only disliked by the boss, but also disliked by him.

Even if he can recover all the 8,000 tons of space junk in Earth's orbit, the precious metals extracted are not worth much. You must know that his total income last year was nearly 80 million yuan, and this year should be even more. There are many, and the company's side is not so bad, so this aspect is really not worth considering.

They are high-tech companies, and it’s okay to have some fun in recycling garbage. It really makes them collect garbage down-to-earth, even if it is space junk, he is unwilling to do it.

But the boss said that the space junk that has been floating in Earth's orbit for decades is a treasure,

He really recognized it, and the boss didn't think about it unless the boss said it.

You must know that corrosion is a common phenomenon in people's daily life. Whether it is metal or wood products, over time, they are inseparable from the fate of being corroded. Even plastic products that are difficult to degrade in nature, It will also be slowly eroded under the gnawing of microorganisms.

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

Even if there is no water and air in outer space, whether it is metal or other materials, they will be corroded, and the situation is far worse than the earth. So, what is causing this phenomenon? Scientists believe that the following three substances are gnawing the spacecraft.

The first is radiation. Radiation is almost ubiquitous in the universe. It includes not only the energy remaining in the universe after the big bang, but also the high-energy radiation released by major celestial bodies in the process of collision with each other or the formation of supernovae. The sun, which is alive, also radiates powerful radiation energy to the earth at all times.

It is worth mentioning that the reason why the organisms living on the earth are not affected by radiation is mainly because the earth has a thick atmosphere, which not only ensures that the human body will not be harmed by radiation, but also makes 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 Earth, but once it reaches the vacuum of outer space, it disappears without a trace.

The reason why the spacecraft is subject to oxidation is mainly because when it is launched from the earth, the first contact is with the environment in the low orbit 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 is oxidized, which leads to 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 spacecraft materials, thus making the spacecraft materials brittle and aging. even fall off.

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