Can the moon become the second home of mankind? Tell the answer and explain the reason.

"The earth is the cradle of mankind, but mankind will not live in the cradle forever." -(tsiolkovsky)

The 20th century is the most brilliant century in human history. In this century, human beings walked out of its cradle-the earth for the first time, leaving footprints on the moon, which has been entrusted with the beautiful dreams of human beings for thousands of years. With the coming of 2 1 century, the pace of human marching into space will be greatly accelerated, and the primary goal is to establish a space base on the moon and immigrate to it.

To move to the moon, we must first solve a series of basic problems such as life support, life and work on the moon, such as the supply of water, air and food, the protection of cosmic radiation, and the adaptation of lunar gravity. Among them, the problem of water is the most critical.

1June 1998, the lunar probe was launched. It flew around the moon for two months and found data signals showing the characteristics of water molecules in the north and south poles of the moon, which proved that there was a lot of frozen water on the moon. These waters may be brought by meteorites or comets, and the estimated reserves are 40 million to120,000 tons, which can be used by at least 2,000 people 100 years.

With water, as long as oxygen and nitrogen are extracted from the soil of the moon to synthesize air and a closed ecological circulation system is established, plants and animals can be planted on the moon, and the problem of food supply will be solved.

There are two basic requirements for the location of the future lunar base: one is to be close to the water source near the polar regions of the moon, and the other is to have enough sunlight to provide solar energy. Because the geological structure of the moon surface is much more stable than that of the earth, with the support of future science and technology, it is possible for human beings to give full play to their imagination and creativity and build their own magnificent and comfortable moon home.

With the support of life support system, people can make use of the lunar environment with high vacuum, strong radiation and low gravity to develop the rich resources of the moon and carry out scientific research in life science, astronomy and high-energy physics. As a bridgehead for human beings to enter space, the moon will provide most of the raw materials for the construction of future space cities, high-orbit space stations, space ports and other planetary bases.

The moon is the closest celestial body to the earth, and its gravity is only one sixth of that of the earth. Soil contains 40% oxygen, which can be used as rocket fuel and is the most ideal space base and transit station for human beings. After human beings move to the moon, they can launch heavier spacecraft with rockets with lower thrust, and the cost is much lower than that from the earth.

The moon is also rich in helium -3, which is an ideal raw material for nuclear fusion reaction, and there is no such resource on earth. This unique treasure can not only provide sufficient non-toxic and non-radioactive energy for the lunar base, but also serve as the best fuel, providing powerful power for future nuclear spacecraft and helping mankind truly realize the dream of "space navigation".

2/kloc-On a weekend in the 20th century, people on earth may forget their busy week, take a convenient "space bus" to a space transit station in Earth orbit, and take a regular "Earth-Moon flight" to visit relatives and friends at the moon base. At that time, the word "moon" may only be found in history books, because the moon has become the eighth continent on the map of mankind.
