What can the Chinese do? If you want to go to the moon to "mine", and find a way to transport it back, technology? Indeed, I am really happy to see the news, and I have told you before that the lunar resources are very rich, and there are even more rare resources.
If that country can lock in lunar resources in advance and has the ability to develop, transport, etc., it may get the world's "first opportunity" in the development strategy of the moon.
Therefore, it must be a good thing to see the new technologies, new methods, and new schemes that can be transported back from the lunar "mining" proposed this time, after all, there is no country that can realize it, which highlights the importance that the mainland attaches to this direction in the aerospace field, so what is going on?
This is the overall scheme of the new technology of the moon-based magnetic levitation rotary projectile return system proposed by the Shanghai Key Laboratory of Deep Space Exploration Technology and the Magnetoelectric General Department of the Academy of Aerospace Science and Industry Flight Technology.
Whether this is realistic or not, let's first explain the "mining" of the moon, what resources are on it, and then talk about the plan.
What exactly is the "rare resource" of the moon?
That's right, whether it's a continental mission to the moon, or a mission to the moon by other countries, whether it's to understand the moon or the future strategic plan of the moon, in fact, one of the most important tasks is to find rare resources on the moon, and "collect" them and transport them back to Earth.
And the fact is that the moon has a lot of resources, very rich, many of them that are not available on Earth.
What are the "rare resources" of the moon? Yes, the moon can be said to be a "treasure trove of resources", in the lunar soil, it contains various mineral elements, for example, the oxygen content of the lunar soil is 40%, from which the oxygen can be extracted as a rocket propellant, and it can also be used to replenish the spacecraft in orbit or synthetic water for human use, with a silicon content of 20%, which can be used for solar cells, as well as aluminum (14%), iron (4%), calcium and a small amount of titanium, manganese, magnesium, chromium and other elements.
The most critical and rare resource, and the resource that human beings care about the most, is helium-3, once humans can mine this resource and transport it back to Earth, it will be the moment when human beings break through the "energy pattern".
Helium-3 is considered the "perfect energy source" and is considered to be an efficient, clean and safe fuel for controlled nuclear fusion power generation.
However, it is very scarce on Earth and is basically invisible, while on the Moon it is too much, and it is estimated that the total helium-3 content of the lunar soil layer is about 1 million to 5 million tons, which can be used by humans for more than a thousand years.
The substance has also been discovered by the mainland Chang'e-5 before, and when it was announced, it also caused a worldwide sensation, which may be why, many countries in the world have applied for China's Chang'e-5 lunar samples, hoping to achieve some research.
The same is true for the United States, which can even ignore the "Wolf Clause" and apply for it, but in the end it is not known whether the mainland will share it.
It is just that the lunar samples of China's Chang'e-5 are extremely valuable, and they are some "high-quality" lunar soil that no other country in the world has at all.
Therefore, if you get a sample of the Chinese Chang'e-5 moon, you may be able to analyze the content of some lunar minerals, and this is the factor.
However, after the discovery of lunar minerals, how to return them at a uniform speed is the key, including in 2024, the United States has also announced that it will go to the moon to mine helium-3 and transport it back, but there is no clear plan yet.
No, the continent has proposed some models in this regard, which will make it possible to transport the "rare resources" of the moon, but here we need to take the lead in explaining the new methods built on the "ideas".
The moon was "mined" and transported back to Earth, and China proposed new technology
True, it is a matter of time before the moon "mines", and transporting it back to Earth, no matter how difficult, is also a trend in the future.
The new technology proposed this time is to carry out the mode of "Chang'e throwing hydrangea" to send lunar minerals back to Earth. It is mainly to establish a moon-based magnetic levitation rotary projectile return system, using the characteristics of high vacuum and weak gravity of the moon, only need a speed of 2.4km/s to "throw" the cargo container filled with helium-3 to the earth - it can also be said to directly send the lunar "minerals", rare resources, back to the earth.
And this is much simpler than the technology that humans have, using a rocket on Earth, launching a returner to the moon, and then transporting it back to Earth after loading.
In detail, this projectile system is under the overall operation of the system, and then the energy storage device transmits electrical energy to the superconducting motor through the converter, and the superconducting motor provides suspension and driving force for the spiral arm, and the returner and the spiral arm rotate and accelerate in the suspension state. After acceleration, a predetermined value of "lunar escape" can appear.
It separates and then enters the return route, even if it does not directly enter the predetermined orbit, the returner can directly correct the orbit to reach the standard return orbit.
However, the returner then passes through the moving orbit and enters the moon-Earth return orbit and then returns to the Earth, which improves the angular accuracy of the projectile into orbit.
Compared with the sample-return mode that has been utilized, this mode actually turns the bottom lander into a "catapult", and then executes this process. This can be seen from the new technical drawings that have been published.
However, according to the assumption, this system has a low estimated single launch cost of the whole system, and can be used for a long time without limit under the condition of good maintenance, and its transmission frequency is high, and theoretically a single system can achieve more than 2 times / day of repeated launches.
Therefore, it seems that it can still be done, but this proposed new technology actually faces many difficulties, such as facing problems such as high-speed and smooth rotation, high-precision ejection, and extreme environment on the lunar surface.
Do you think it's feasible?
Whether it works or not, it's a solution
Indeed, whether this works or not, it shows that it is the embodiment of a new technology and a new solution.
Moreover, only with more exploration can it be possible to find the best solution. Therefore, it is expected that such an innovation will appear, because it is only a matter of time before the collection of lunar resources is carried out in the future.
Isn't the construction of a lunar base and the establishment of a permanent base in the future due to these factors?
Therefore, it is necessary to accelerate the development of technologies such as "mining and transportation" on the moon, as long as one country takes the lead in the front, it may lead to explosive enhancements.
However, at this stage, there are many lunar exploration missions in various countries around the world, but there are few countries that are really powerful, so there is still time, just continue to explore and find out the best way, this is the general situation.
