Did you find out? In the past two years, China's new discoveries on lunar exploration are particularly numerous, as long as the new discoveries of the Chang'e spacecraft and the Jade Rabbit lunar rover must be big news, and they are on the hot search list, and they are constantly brushed by netizens, but American scientists have become silent and have not published new discoveries on the moon.
Recently, the Yutu 2 lunar rover saw the "mysterious hut" in the distance, with two working days to approach, the result of a closer look, the "mysterious hut" is actually a moon rock like a cute rabbit, Chang'e 5 found "moon water", the water content of the lunar soil is as high as 120 grams per ton, and the water content of the moon rock reaches 180 grams per ton.
Just recently, China's lunar exploration has once again ushered in a good news, China's lunar exploration 4 project has officially started, but in the next 10 years, the Chang'e series of spacecraft will land on the moon three times, which means that China has opened a new chapter of lunar exploration, which is of great significance to all mankind.
What did the Chang'e spacecraft do when it landed on the moon?
Wu Yanhua, China's top lunar exploration scientist, stressed: There are three major space missions that need to be completed.
First, the exploration of the lunar south pole, as we all know, the earth's south pole is one of the coldest and most mysterious regions on the earth, there are endless mysteries, then the lunar south pole will not also be one of the most mysterious regions on the moon? So the lunar south pole is worth exploring.
It is planned that the Chang'e 7 spacecraft will first land on the lunar south pole, Chang'e 7 is an upgraded version of Chang'e 4, also carrying a lunar rover, which will conduct a comprehensive exploration of the topography, material composition and space environment of the lunar south pole, and then conduct a comprehensive assessment of the lunar south pole and whether samples are needed to be returned.
Second, the lunar south pole sample return, the launch of Chang'e 6 spacecraft, Chang'e 6 is the sister version of Chang'e 5, with sample return capabilities, before chang'e 5 preparatory spacecraft, in case Chang'e 5 launch failure, Chang'e 6 will replace Chang'e 5 to perform lunar sample return missions.
But now That Chang'e 5 has successfully retrieved lunar samples, everyone knows that Chang'e 5 lunar samples have obtained a lot of research results, so The mission of Chang'e 6 will be to return to the lunar south pole to take samples.
Third, the basic type of the establishment of the lunar research station, after the successful return of the Chang'e 6 lunar south pole sample, followed by the launch of the Chang'e 8 spacecraft, the main task of the Chang'e 8 spacecraft is not to explore, nor to sample, but to establish a basic type of lunar research station on the moon.
The basic type of the lunar research station is a test mission to establish a lunar scientific research station, to know that the lunar surface environment is worse than Mars, the daytime temperature is as high as 120 ° C, the night is as low as minus 180 ° C, after passing the test, it is necessary to establish a real lunar scientific research station, the future Of our astronauts will live in the lunar scientific research station.
Why should China build a lunar research station?
Lunar research stations are not so easy to build, to solve a number of space problems that have never been encountered, for example, the problem of the source of life for astronauts, is it mainly self-sufficient, or completely dependent on spacecraft for transportation? How astronauts operate on the moon and what kind of machinery they use.
The construction of lunar scientific research stations also consumes a lot of money, and the cost of replenishment of space stations in low Earth orbit itself is very high, and the cost of transporting a kilogram of materials is almost 70,000, but to transport materials to the moon 384,000 kilometers away, I am afraid that the transportation cost will be several times higher.
Lunar research stations are both difficult to build and very expensive, so why should China work hard to build them?
First, the moon contains a large number of resources, including thorium (Th) and titanium (Ti) ore, especially the clean energy helium-3, which is the best material for nuclear fusion, which is the most scarce resource on the earth.
Although the earth has rich resources, but according to the current scale and speed of mining, it will not be long before some rare resources will be exhausted, but there are on the moon, if human beings can achieve lunar mining, this is undoubtedly more conducive to the development of human civilization.
Second, the earth is not an absolutely safe planet, the earth's 5 mass extinctions have proved the fragility of life, every once in a while, a large number of life is destroyed, including the invincible dinosaurs, becoming the comet hit the earth victims.
In the future, if humans want to avoid comets hitting the earth, the most effective way is to back up human beings and colonize some humans to other planets, which is the meaning of colonizing Mars, but the moon is the closest planet to earth, and it can be used as a springboard for humans to colonize other planets.
Third, the ultimate mission of the existence of intelligent life is to conquer the universe, sprinkle the seeds of life on every suitable planet, and make the entire vast universe full of vitality, and the moon will become the first stop for human beings to conquer extraterrestrial planets.
At last
In the next 10 years, China's Chang'e spacecraft will land on the moon 3 times, Chang'e 7, Chang'e 6 and Chang'e 8, China's aerospace opened a new chapter in lunar exploration, when China's lunar exploration 5 project was launched, it was time for Chinese to land on the moon, and it has to be said that China's aerospace has become very strong.
