6 times!
So far, humans have successfully landed on the moon 6 times. It was completed by the United States using Apollo , in July and November 1969, February and July 1971, April and December 1972 respectively.
These 6 successful landings on the moon, explored the central plateau of the moon, collected lunar samples, and stayed successfully for 75 hours in the last time. If we can establish a foothold on the moon, it will be a huge progress in human exploration of the universe in the future.
This time, if nothing unexpected happens, China will become the second and the seventh country in the world to successfully land on the moon.
will realize the Chinese dream of "flying to the moon" for thousands of years.
Many beautiful science fiction scenes in " Loneliness Moon " which was popular this year may all have the opportunity to see them with our own eyes in the near future.
Why are humans so persistent in exploring the moon and landing on the moon?
mainly considers three aspects.
First, it is to facilitate humans to better observe the universe.
According to scientific analysis, the moon has high cleanliness and weak gravity characteristics, and is extremely suitable for celestial observation. Especially the geological activities on the moon are very little, and the impact on telescope observation will be much smaller. Once humans establish a large lunar-based observatory and scientific research base on the moon, it will provide more favorable conditions for humans to observe cosmic celestial bodies.
2 is to promote scientific research and industrial development.
Moon exploration is a very complex systematic project. Through lunar exploration activities, human beings are constantly exerting their imagination and developing science and technology to facilitate the successful realization of lunar exploration. This has driven and promoted the rapid development of basic scientific research and high-tech in disguise, and promoted the cross-section, penetration and common development of multiple disciplines.
Like Musk's company, it has been conducting commercial rocket launches, lunar exploration, landing on Mars and other projects. The continuous development of such projects has allowed Musk's company to always stand at the forefront of cutting-edge technology innovation companies. Our country's aerospace companies conduct scientific and technological research such as moon landing plans, which will also stimulate the continuous development of science and technology , and thus achieve the goal of a top science and technology power.
The third aspect is to explore resources on the moon.
Scientists' analysis shows that the moon contains a large number of natural resources, and there are more than 100 known minerals, such as titanium, iron, uranium, thorium, rare earth , sodium, potassium, nickel, chromium, manganese and other minerals. In the html February alone, the sea basalt can be mined, at least 100 trillion tons of titanium can be mined. There are even five kinds of substances in it, not even on the earth.
In addition to these purposes, landing on the moon can also explore more unknown things. Many people are curious about the "mysterious back of the moon". The first country in the world to explore the back of the moon was the former Soviet Union. Before the Apollo landed on the moon, the former Soviet Union took more than 20 confidential photos of the back of the moon with a probe. Later, Apollo landed on the moon to conduct an investigation and found that there were many large and small meteorite craters on the surface of the moon.
Scientists judge that this is the moon that has suffered countless impacts in the past billions of years, and has helped us block countless meteorite impacts.
Some people say there are aliens on the back of the moon. Even Stephen Hawking During his lifetime, they said that there are very likely mysterious creatures on the back of the moon. Once warned humans not to explore too much, so as not to "preserve the weak."
. The United States Apollo 17 has landed on the moon for the sixth time on December 11, 1972. After staying on the moon for 75 hours and returning to Earth, the United States has never landed on the moon again. The reason can be said to be different. Some people say that Apollo's lunar exploration is a scam, and there is another saying that the cost of manned lunar exploration is too high, and huge investment has not achieved considerable returns.
In any case, if China conducts manned moon exploration, many puzzles may be solved one by one with our strong scientific and technological strength.
