China's Yutu-2 found alien material on the far side of the moon for the first time!
As we all know, on January 3, 2019, the "Chang'e-4" lunar probe launched in the second phase of China's lunar exploration project successfully launched its own inspection work on the soft landing on the far side of the moon, which is also the first time in history that human beings have landed the probe on the mysterious far side of the moon. The Yutu-2 is the rover carried by Chang'e-4, and its function is naturally not weak. Not only is it equipped with panoramic interstellar, but also with a visible-near-infrared imaging spectrometer, so that ground workers can see clearer images of the lunar surface and those complex hyperspectral data.
In fact, the moon we usually see has always been facing us on the same side, even if the United States has explored the moon for so many years, every time it lands on the front of the moon, so the significance of the Chang'e-4 mission, even for all mankind, is also significant and far-reaching!
No, Chinese science has made another discovery:
There is extraterrestrial material on the far side of the Moon, and the distance from the current time should be within 1 million years!
Although carbonaceous chondrite meteorite fragments have also been found in previous "Apollo" samples in the United States, humans have never been directly observed by remote sensing on the lunar surface. This means that the "Jade Rabbit II" carried by China's Chang'e-4 has found special residues that did not belong to the moon for the first time in the lunar impact crater!
Where did the "alien visitor" come to the moon?
The discovery of this extraterrestrial material is indeed based on the observation of Yutu-2, but it is also inseparable from the study of spectral data and images by Chinese scientists. To put it simply, this kind of material that does not belong to the moon is actually left by a carbonaceous chondrite meteorite after hitting the moon, but it is this inconspicuous material that may provide water for the moon!
Originally, Yutu-2 only found a relatively "young" impact crater, but the residue inside attracted the attention of researchers because its spectral information was different from the typical lunar soil and rock inside and outside the impact crater. People may not understand it too professionally, so the researchers also said that first of all, there is a difference in color:
The soil and rocks on the surface of the moon will show the characteristics of "redness" in the reflection spectrum, and the moon will also be subjected to stronger effects of space weathering, so its redness will look more obvious.
But the residue in the impact crater is different, its spectrum is not only not reddish, but shows the characteristics of "bluening", the former is due to the increase in wavelength and reflectivity increase, the latter is because the wavelength increases and shows a decrease in reflectivity, which is completely opposite performance.
The reason why this residual material should be left by carbonaceous chondrite meteorites when they hit the moon is not difficult to understand, because scientists have only found this "blue" feature in the spectrum of carbonaceous asteroids. In order to make this conclusion more rigorous, the researchers also collected a lot of spectral information about carbonaceous chondrite meteorites, and confirmed through strict comparison that the young residues found in this lunar crater are indeed very similar to the spectra of this meteorite.
Subsequently, the researchers also based on the relevant information collected by Yutu II, conducted a professional simulation, from the analysis of the situation, this impact crater can not be a secondary impact crater, numerical simulation technology shows: the impactor of this small impact crater, because the diameter of the gaga i is 15 cm, the running speed of 15 kilometers per second, and then left some residue after the impact, which is why it can be concluded that the object that hits the moon should be a small carbonaceous meteorite.
Will the moon eventually become a base for humanity? NASA says it will build a nuclear power plant on the moon!
In the past, the United States was a famous space power, but after decades of catching up, we have also become one of the space powers. We can't get on the International Space Station, so we build a space station ourselves, no manned landing on the moon before, but it doesn't affect us to become the first country to land a probe on the far side of the moon!
The Earth's environment is as you can see, with global warming making the Planet less livable than it was a hundred years ago, and extreme weather events becoming more frequent. From the evolution of the solar system, it is true that the earth can not be forever for human reproduction, and it is necessary to find other planets suitable for life to live, so scientists in many countries are studying planets other than the earth, including the moon that is closer to us.
I don't know if you have seen that NASA has publicly stated that it wants to build a nuclear power plant on the moon in 2030, and is soliciting suggestions from all citizens, such as: how to install a uranium-powered nuclear reactor for a 4-meter rocket? That is, the United States hopes that it can send a durable, high-power reactor to the moon within 10 years.
Of course, scientists need to complete the assembly of the reactor on The earth first, its weight can not exceed 6000 kilograms, but to ensure the normal operation of this reactor, it is necessary to continuously provide 40 kilowatts of continuous power, the focus is that the temperature of this reactor also needs to be controlled, which can ensure that the equipment remains cool, and the purpose of doing all this is to make the moon a base for human beings, a base to help humans explore aliens, such as the probability of success of humans landing on Mars and going directly. It is likely that it was not higher from the moon.
The United States once Apollo series of moon landing program, has sent 12 astronauts to the moon, but also brought back to the lunar soil, but there are still people questioning the authenticity of the moon landing, and this proposal to build a nuclear power plant on the moon, in fact, in addition to strengthening the Artemis moon landing program together, that is, the United States has been ready to return to the moon, is expected to cost 93 billion US dollars, from this figure can also be seen, the moon landing is really not only a technical problem, but also the cost is really high!
