The Chang'e-6 probe was officially launched on May 3 with the eagerness of various countries and is expected to return to Earth in 53 days.
I think that Chang'e-4 was responsible for taking "back photos" of the moon, and No. 5 was responsible for "digging" on the front side of the moon, so what will Chang'e-4 do this time?
The Chinese pay attention to one step at a time, and the successor, Chang'e 6, is to dig the far side of the moon.
Go dig on the far side of the moon
The scientific research work is quite rigorous, so Chang'e-6 must not find a place to land casually, the lunar probe has a limited payload, and the only two kilograms of lunar soil must be achieved step by step as much as possible.
After thousands of selections, mainland researchers finally chose the south pole of the moon - the Aitken Basin, the oldest and largest impact crater on the lunar surface.
Speaking of which, some friends may want to ask, didn't we already dig up the lunar soil back then? Something else may not be remembered, the fact that the moon cannot grow vegetables makes the Chinese people very uncomfortable.
Could it be that everyone is "soil", and can the front of the moon be different from the far side of the moon?
Not to mention, there are different mineral deposits on the earth's veins, and the front and back of the moon are a little different, isn't it normal?
Besides, the human moon is different from ours, it also rotates and rotates, it only takes 24 hours for the earth to rotate once, but it takes more than 360 days to rotate around the earth. In stark contrast to the Moon, its rotation and revolution speed are the same.
In other words, what we earthlings see is always the face of the moon, what does the far side of the moon look like? If it weren't for Chang'e-4 to take pictures, everyone wouldn't know about it!
The long face-to-face encounters also led to another problem, the far side of the moon has endured an unknown number of rounds of meteorite bombardment compared to the front, which has left the far side of the moon hollow, but also buried more evolutionary secrets under the ancient lunar crust and highlands.
And the composition of the lunar soil on the back can also be compared with the composition of the lunar soil on the front, and see if some "lunar specialties" are evenly distributed across the entire planet.
All of this is laying the foundation for the future, and it seems that it is no longer too long ago for humans to build a base on the moon and launch an assault on the vast sky.
The battle for lunar soil has begun
What is enough for two kilograms of soil? The larger pots couldn't fill up, so I barely managed to plant two lettuces.
Don't confuse lunar soil with soil for growing flowers and vegetables, scientists use lunar soil for scientific research.
Think about the 1.5 grams of lunar soil that Macron took away during his visit to China, don't think that 1.5 grams is too little, even if you give scientific researchers 0.1 grams of lunar soil, they can write you several papers.
Looking at it this way, it is not just two kilograms of soil, but the future of a country's and even the world's lunar exploration program. What countries around the world want to break through the sky first, and when the Chang'e-6 lunar exploration project was still in the planning cycle, waves of people wanted to book it.
Why is everyone worried about the "soil" dug up by the mainland? With so many developed countries, can't they dig a little bit into the sky themselves?
Looking at the whole world, there are not many countries that have the ability to land on the moon, but they are not very few, and China, the United States, and Russia naturally do not need to say much, India achieved a soft landing a few days ago, and ESA thought that it was also brilliant back then.
But those who have dug soil on the moon, so far, only China and the United States, in fact, there are three, strictly speaking, in fact, there are three who say that the Soviet Union has collapsed. And digging to the far side of the moon, only China is currently underway.
Why don't you go? Is it because you don't want to? Now that I've snatched my head, I don't look like I don't want to.
Going around and going around is back to that problem, the strength is not enough.
The lunar probe from going to the sky, changing orbits, landing on the moon, and then to observation, sampling, and return is a rather delicate and tedious process, and the difficulties to be overcome can probably be written in several books.
The process of going to the far side of the moon is more complicated, and there are several stages of preparation that must be made.
To take the simplest example, since the Moon is "face-to-face" with the Earth 24 hours a day, 365 days a day, there is no signal on the far side of the Moon if there is no special relay satellite.
That is to say, if you want to complete the operation on the far side of the moon, you must first get the relay satellite system, which is available in China, the United States, Britain and Russia, but the signal network is laid to the far side of the moon, and only China's Queqiao-2 is currently available.
The second great voyage of mankind requires not only a lot of technology, but also a lot of money. And the biggest headache is that even if enough upfront investment has been made, it may still die in outer space.
For some countries, why waste that time and money when there is an opportunity to cut corners?
Lao Mei is looking for the mainland to point "soil"?
In 2020, Chang'e-5 brought 1,731 grams of "soil" that was finally dug up, creating a monumental lesson in human history.
Lao Mei has always slandered us for eating "alone" on the moon landing project, but in fact, we have always been very generous to our "friends". Macron came around and took 1.5 grams away, and Putin came to visit China, and we also sent out 1.5 grams.
By the way, it needs to be added here that most of the lunar soil dug by the USSR in the last century was in Russia. At the beginning of 2023, Russia gave the mainland another 1.5 grams of lunar soil, which are all old antiques brought back in 1970 and have great research value for mainland scholars.
This makes it seem that the pattern of the United States is too small, didn't they say that they dug up a total of more than 700 catties of lunar soil? It didn't matter if you didn't give it back then, why don't you still want to exchange gifts now?
Not only that, but at the end of 2023, the U.S. Congress also did a shameless thing by approving NASA to ignore the Wolf clause and apply for a share of lunar soil research like the International Space Administration of China.
And what is the Wolf Clause? How can non-principled academic research need to go beyond the bill?
Thirteen years later, in order to restrict the development of China's aviation industry, the United States set a Wolf clause, completely prohibiting all exchanges between China and the United States in aviation scientific research.
Under this clause, unless China diplomatically sends a portion of lunar soil to the United States, NASA simply has no way to apply for a research share from the Chinese space agency.
How can foreign scientists also apply for the lunar soil that our country has obtained?
It turned out that on October 6, 2023, the China Space Administration opened the qualification application for the 7th batch of lunar samples to the world, NASA couldn't sit still at that time, they "asked" for several rounds, China has not been able to read back, and now that there is finally a "formal channel", people are not allowed to work hard?
As for whether China will pass it, or even whether it will give a part of the hard-earned money of Chang'e-6 to the United States, it will depend on the attitude of the United States.
