Chapter 835

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

"Is this net strong enough? I don't think the thickness of the net is very thick After observing for a while, Lei Tiantang points to the capture net in the projection and asks.

"The thickness is enough by calculation. Although it seems that the net looks very ordinary, and the thickness is only 0.5cm, it has 1500 layers!

Because our capture net is woven with the latest carbon nanotube technology provided by the materials company, its strength is very high. At the same time, because the density of our weaving is also very dense, and the mesh is small enough, our space waste processor can clean up the space garbage with a minimum diameter of 0.5cm. This design has fully met the boss's requirements Yes!

According to our actual test data, even under the impact of 2000 meters per second, the capture network will not be broken, so there is no need to worry about its problems when it works Zhang explained.

Lei Tiantang nodded, then groped his chin and said, "I have seen that there is no problem with your design. The first generation design can use this one.

But it would be better if we could add a parachute system to this space waste processor. I think, although the space garbage looks like garbage, it doesn't mean that they are worthless.

For example, the satellites that can't be used due to accidents and other reasons are very valuable. If such satellites are retrieved, we don't need them, but we can sell them. Although we can't make much money, there is a lot of fun in it.

You see, if the countries where the satellites belong don't want 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 do people care about some of these things?

And I think those satellites launched around the 1960s are also a valuable asset after they are recovered. It is not that their materials are valuable, but that we can directly see the corrosion effects of various metal materials and other types of materials in the space environment.

The corrosion effect in this natural environment is certainly different from the space environment simulated in our laboratory, and these data will be very helpful for our company to build spaceships in the future.

If we want to know that our future spaceships will often fly for tens of thousands of years in space and even travel far away to other galaxies, it is possible for thousands of years with our current technology. In such a long time, whether the shell and internal parts of the spacecraft can cope with such a long time of corrosion is a matter that needs to be considered.

If we have more data in this area, we can have more confidence in the design of future spaceships. Do you understand me

Lei Tiantang said that Zhang hanxiu didn't understand what he didn't understand. The recovery of abandoned satellites in front of him was a small matter. At most, he had to have some fun or something. This matter could be done. Anyway, the company took the initiative, and there was no problem in how to operate it.

As for other space wastes, they are made of precious metals such as gold, platinum, etc., but these things are not only looked down upon by the boss, but also by him.

Even if we can recycle all the 8000 tons of space waste in the orbit of the earth, the extracted precious metals are not worth much. We should know that his total income last year was nearly 80 million yuan, and this year should be more. The company is not short of such money, so it is not worth considering.

They are high-tech companies. It's OK to have some fun in recycling garbage. They really let them collect garbage in a down-to-earth manner. Even if it's space garbage, which is high-rise garbage, he is not willing to do it.

However, the boss said that the space garbage that has been floating in the earth orbit for decades is a treasure. He really agrees with it. The boss has never thought about it.

We should know that corrosion is a common phenomenon in people's daily life, whether it is metal or wood products, as time goes on, they are inseparable from the fate of corrosion, even if it is difficult to degrade plastic products in nature, they will be slowly eroded under the "gnawing" of microorganisms.

The corrosion of metals is mainly reflected in chemical reactions. For example, 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 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 more serious than that of the earth. So what is the cause of this phenomenon? Scientists believe that the following three substances are "nibbling" the spacecraft.

The first is radiation. Radiation is almost everywhere in the universe. It includes not only the residual energy of the universe after the big bang, but also the high-energy radiation emitted by the major celestial bodies in the process of collision or supernova formation. Even the sun, which we depend on, also radiates the powerful radiation energy to the earth at all times.It is worth mentioning that the reason why living creatures on the earth are not affected by radiation is mainly because the earth has a thick atmosphere, which not only ensures that human body will not be damaged by radiation, but also allows the sunlight to continue to glow and heat through the earth.

And the second substance is the most common oxygen we are exposed to in our daily life. Oxygen is ubiquitous on earth, but once in the vacuum of outer space, oxygen disappears.

The reason why the spacecraft is subject to oxidation is mainly because when it is launched from the earth, it first contacts the environment of the earth's low orbit area, where the oxygen content exceeds 80%. However, under high temperature, oxygen rich spacecraft surface materials are oxidized, which leads to corrosion.

The last one is temperature. Since the big bang, the temperature of space has been continuously decreasing. Today, the space temperature has been as low as minus 270.3 degrees. The extreme temperature environment will affect the strain stress of spacecraft materials, which will make the spacecraft materials brittle, aging and 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!
