What is the significance of human landing on the moon?

First, the energy of the earth where human beings live will be exhausted one day, and it is an important scientific research topic for human beings to seek new energy. As the most faithful satellite of the earth, the moon is the energy warehouse on which human beings will live in the future. The volume of ilmenite in the basalt above it accounts for 25%, and titanium is about 10 trillion tons. In the future, mankind can directly use this basalt to produce water, liquid oxygen fuel and other resources. There are abundant mineral resources on the moon, such as uranium and rare earth, especially helium -3, which is unique in lunar soil. As the raw material of nuclear fusion, it will change the energy structure of human society and become an inexhaustible energy treasure house for human beings in the future. There are millions of tons of helium -3, 1 ton of helium -3 in the surface soil of the moon, and the electricity generated is enough for all mankind to use 1 year ... Second, the surface of the moon has high vacuum, no magnetic field, stable geological structure, weak gravity and high environmental cleanliness, which can be used for the development and research of biological products and new materials; The back of the moon is not disturbed by the earth's radio waves, so it is possible to establish a lunar astronomical observation base and laboratory and build the moon into a frontier post for human beings to explore the starry sky in the universe. In a word, the moon is an ideal place for human beings to study moon science, astrochemistry, space physics, life science, earth observation science and materials science. Third, a series of technological revolutions and progress triggered by human exploration and landing on the moon have become new technical support for social and economic development, promoted and promoted a series of innovations and developments in basic science and technology, formed a large number of high-tech industrial groups, and produced remarkable social and economic benefits. At that time, the Apollo moon landing program in the United States cost a lot, reaching $26.5 billion, but it created more than 3,000 new technologies in radio guidance, synthetic materials, high-performance computers and other high-tech aspects. Judging from the economic benefit evaluation, every 1 US dollar invested in the Apollo moon landing project can generate 4 to 5 US dollars, which shows that the economic benefits of human exploration and landing on the moon are enormous and immeasurable.
