After Chang'e-5 in 2020, the lunar soil was brought back, and the United States has been thinking about it!
NASA not only issued a message to congratulate Chang'e-5 just after it took off, but its director Bill Nielsen even issued a message in early May 2022 saying that China should share lunar soil with other countries, because the United States gave us 1 gram of lunar soil that year, but China did not give a gift in return.
Chang'e-5 brought back 1,731 grams of lunar soil, and then NASA began to play all kinds of demons.
Of course, if the relationship between China and the United States is normal, China can give back the lunar soil, after all, the United States gave China one gram back then (from the perspective of scientific research, one gram is enough for scientific research, or even half a gram is enough)
But it can't stand up to the US blockade of China:
The 1999 "Cowsk Report" slandered China's aerospace as espionage, and the lethality of this report was too great for China, because the cost of China's series of rockets was relatively low, and it had very important commercial value in the world, and this report led to the fact that the Western world would not use China's aerospace for commercial launches, and whoever gave China a commercial order would be sanctioned - the United States is so hegemonic.
The silver of the white flowers is gone······ China's aerospace industry is making hundreds of billions of dollars less on the scale!
In 2011, the United States came up with the Wolf Clause, prohibiting China from participating in international space activities, and even prohibiting Chinese experts from participating in international scientific research conferences!
It's just that the United States did not expect that the Chinese would be so fierce! I made a manned spaceflight, and returned from the moon to explore Mars!
So after China's Chang'e-5 retrieved lunar soil, why is the United States in a hurry?
The United States has landed on the moon six times and brought back 382 kilograms of lunar soil, although the more you look at the matter of the United States' manned landing on the moon, the more problematic it becomes, but in fact the United States has really landed on the moon, but there is a problem with the photos and videos he released, and the places where the United States collects lunar soil are relatively concentrated.
The 382 kilograms of lunar soil are very similar, and the United States has studied them thoroughly for so many years. In addition, the United States has poorly preserved the lunar soil, resulting in a certain amount of lunar soil being polluted, and American researchers could not have imagined that the United States would never land on the moon again after 50 years.
Chang'e-5 sampled the northern side of Mount Lumke in the northern part of the Storm Ocean, which was once the youngest volcano on the moon, and the samples obtained here are of great value for the evolution of the moon, which has made the United States angry.
Secondly, the lunar soil brought back by China is very special - there will be color changes, that is, when excavated, it is dark, and soon after the sun is exposed, it becomes white, which is completely different from the samples from the United States and Russia.
Since then, NASA Administrator Bill Nelson has asked China for lunar soil, which has become a "menstrual patch", which is often mentioned.
But China's attitude is very clear, you can't do it, should your two own laws be repealed? This NASA can not be said or not.
Of course, there is one thing that makes NASA even more furious: in February 2022 and April 2023, when Russian President Vladimir Putin and French President Emmanuel Macron visited China, China presented 1.5 grams of lunar samples for scientific use to Russia and France respectively.
This move made NASA angry, and the NASA administrator began to publicly slander China, calling for a ban on other countries from participating in China's space station program.
Subsequently, China announced that it would allow the world's scientific research institutions to apply directly to China for lunar samples.
That is, your scientific research institution, as long as it is an excellent and capable scientific research institution, does not need to go through the national government level, you can directly apply to China, this policy is exactly the same as the model of Tianyan in Guizhou.
However, NASA of the United States is still blaming China in a shrewd style at this time. However, important scientific research institutions around the world have actively submitted applications.
China will not monopolize the research of lunar soil on its own, but share it with the world, and the first batch of lunar scientific research samples totaling 17.4764 grams will be distributed to 31 applications from 13 scientific research institutions, and these samples are for scientific research purposes, each of which is about 1.5 grams.
To the great surprise of the world, scientists from the United States, Britain, Germany, France, Japan and Pakistan came to China one after another, and all other countries came to China with one scientist, and five from the United States came, and finally all of them passed the application!
This made NASA's tongue almost flash, and it was even ridiculed by American scientists, although science knows no borders, but scientists have nationality.
The laboratories and scientists engaged in related research in the United States are all led by NASA, and it is a big deal to go to Moon Rock with China, and the U.S. government needs to come forward, but the superior leaders have not ·····done it, and the scientists and laboratories have done it themselves... Where do you put NASA's face?
At the same time, China has also made clear its attitude that China hopes to establish a global scientific research system, share major basic scientific research results, and tell the world's laboratories and scientists that they should seriously engage in research and not be linked to politics, and that China is open and welcome.
The struggle between politics and ideology is a matter between governments, and it has nothing to do with you scientists, China gives face to you scientists, not NASA, the US government.
In this way, China responded to the U.S. move to send China one gram of lunar soil, which is also reasonable.
Now Chang'e-6 is about to go to the moon for sampling, sampling of the Apollo crater in the Apollo Crater in the Aikent Basin on the far side of the moon, this site is too important, if human beings really want to build a lunar base in the future, this place is the choice, and this crater was formed relatively late, which is of great value to lunar research.
And the Artemis program of the United States is not likely to go to the back of the moon to sample, Chang'e-6 brought back a unique sample.
When the time comes, NASA will definitely want it, and this time, either you cancel the Wolf clause, no longer prohibit China's space from participating in commercial launches in the international market, and open up exchanges.
If you can't do this, it doesn't matter, the Chinese still leave you a way:
The OSIRIS-REx probe, which returned to Earth on September 24, 2023, brought back a 250-gram sample from the asteroid 101955 "Bennu"...
Everyone knows, come and don't be rude!
Thirty years in Hedong and thirty years in Hexi, times have changed!
