"China National Space Administration: No application for lunar samples from foreign institutions"
In fact, the truth is: according to the convention, we only accept domestic scientific research institutions to apply for lunar soil sample research, foreign scientific research institutions want to study, can discharge scientists if The Chinese scientific research institutions, and then apply, is it excessive? Not too much at all, because that's what NASA does!
This month has been allocated to 31 applications from 13 scientific research institutions, corresponding to 21 samples, a total of 17.4764 grams! It is estimated that it will take some time for their research results to be released, but the microscopic images of the lunar soil have been published, changing everyone's understanding of the moon's gray fluttering, but there is a boundless and brilliant microscopic world!
<h1 class="pgc-h-arrow-right" data-track="4" > moon soil is actually colored: what are the ingredients? </h1>
The color of the moon soil brought back by our country is also gray, and the color is even darker than imagined, the particles are very delicate, of course, under the vacuum " exposed" tens of millions of years (maybe hundreds of millions of years), has been extremely dry!
But when you put it under the microscope, the moon soil is colorful, not only yellow, but also brown, and even white and orange and gold, etc., which is really surprising!
Li Chunlai, deputy chief designer of the third phase of the lunar exploration project and chief engineer of the ground application system, explained that the yellow one is generally olivine, the brown one is generally glass, the white one is generally oblique feldspar, and the dark color is generally pyroxene.
This is the basic component of the largest amount of basalt on the moon, in fact, it is a kind of igneous rock, fine-grained dense, the appearance looks roughly black, it is condensed by the eruption of matrix magma, the main component is sodium silica aluminuminate or calcium silica aluminate, the content of silica is about 45-52%, and it also contains high iron oxides and magnesium oxide.
Therefore, there are two possibilities for the formation of igneous rocks, one is that the moon must have suffered from the super impact process of an asteroid, and even the rupture of the lunar crust, the lunar sea was formed in this process, this part of the region suffered a huge impact billions of years ago, the crust rupture, forming a huge magma ocean, cooling after the formation of a relatively flat "lunar sea".
The other is the formation of the early moon and volcanic activity, these basalts came from volcanic eruptions! However, due to the relatively small size of the moon, volcanic activity has disappeared as early as 3-4 billion years ago, but near Mount Lümke in the northern part of the storm ocean where China's Chang'e-5 landed!
This is a volcano that was still active 2.5 billion years ago, and China's Chang'e 5 landing here has a very meticulous plan, because the lunar rock samples obtained by the Apollo spacecraft are basically formed 3-4 billion years ago, so a key link in the origin of the moon is missing!
This is also an important reason why NASA wants to obtain the Chang'e 5 moon rock! Chinese lunar exploration is not decided by patting your head, of course, the choice of landing site is more in-depth planning, such as Chang'e 4 landing in the Von Kármán impact crater in the Eykent Basin of the lunar south pole, because there is the oldest impact crater in the solar system!
At least one of the purposes of China's lunar exploration is very clear, to solve the problem of the origin of the moon and to make up for the most important link in the birth of the solar system, because it is directly related to the origin of the earth!

These colored lunar soils are a mixture of minerals formed after the disintegration of basalt, which is caused by harsh conditions on the lunar surface: the surface temperature can reach about 160 °C when direct sunlight is direct, and as low as -180 °C when there is no sunlight, and the temperature difference is about 340 °C
So this dog shouldn't exist
Although it is no longer a lunar rock in the physical sense, it has become a lunar soil, but there is no difference in composition! Because the moon has no weathering effect, and there is no organic matter, it will not become lunar mud, there is no organic matter (perhaps there is organic matter brought by meteorites)!
So the question is, if the moon soil is added to the water, placed on the earth NNNNNN year, will life be born?
<h1 class="pgc-h-arrow-right" data-track="18" >Why is the American moon rock gray? </h1>
The "whole process" of the Apollo moon landing brought everyone the feeling of being gray, which was really a bit "dark", but there was no rut, only americans had been on the moon, and they said that the land was on the ground!
But after the Chang'e-3 moon landing, everyone found that it was not right, Chinese sent back photos are yellow can be a piece, like going to a loess slope, this result makes everyone exclaim that this NASA moon landing fake hammer, but also posted the photo on NASA's social media, so that NASA is not embarrassed!
But in fact, there is really nothing to be surprised, because friends who play photography know a color temperature, once the color temperature is lowered, what is taken is a cool tone, and after the color temperature is adjusted, what is taken is a warm color, the americans in the moon surface with the film color temperature should be low, early film has this problem!
Therefore, it is not difficult to understand that the cold gray is not difficult to understand, and the Chinese use is a digital camera, the color temperature can be adjusted, and the color temperature can be adjusted, and the color temperature is what we want, of course, it is still our standard habit to operate, so the original Chang'e-3 shot is yellow soil, and later it has become gray, after all, gray is still the tone of the moon soil.
What exactly is the color of the American moon soil?
In fact, and the Chinese is almost the same, there are also american moon rock slices of the micrography, is also as beautiful as mosaic glass, so from the general composition point of view, the difference may not be very large, of course, the formation process and age tell us that the amount of information is greater, in addition to other differences will also have, and the key information is often hidden in inconspicuous details!

I hope that our research results will be released as soon as possible, and everyone is waiting for it!!!
