China will return to Mars by sampling in the future. Why study the soil of other celestial bodies?

In June 65438+February 65438+July 2020, Chang 'e V returned to Earth with lunar soil. This is the first time that China has successfully brought back celestial samples from the earth. This is the second time in 44 years that the world has retrieved lunar soil from the moon after the United States retrieved it from the moon. This means that human beings will further understand and study extraterrestrial objects, and they will be more fully understood. It is reported that China will sample and return Martian soil in the future. Why should it study the soil of other extraterrestrial bodies? I think the main reasons are as follows:

First, the full study of extraterrestrial objects is conducive to the future migration of human beings. First of all, according to scientific research, the earth's resources are limited, a considerable part of the earth's resources are non-renewable, and the growth rate of human beings is much higher than that of the earth's resources. So one day in the future, the earth's resources may be exhausted, and human beings need to find another planet to inhabit. Therefore, a full study of extraterrestrial objects can help us compare the similarities and differences between celestial bodies, which is conducive to the great migration of human beings in the future.

Second, a full study of extraterrestrial objects will enable human beings to have a deeper understanding of the universe, and a full understanding of extraterrestrial objects will enable human beings to have a deeper understanding of the universe. So far, human understanding of the universe is limited to the solar system. In fact, the universe is vast, and our understanding of it is extremely small. Therefore, studying the soil on extraterrestrial celestial bodies can deepen our understanding of other planets in the universe, compare the differences between other celestial bodies and the earth, and then move from the solar system to the Milky Way until we enter the vast universe.

Third, explore whether there are aliens. The third point is a cliche. Hawking said that there must be aliens in this universe. Therefore, a full study of extraterrestrial bodies and soil can help us compare the differences between the earth and extraterrestrial bodies, and we can find out whether there may be aliens in other celestial bodies. If we can find sanitation, it will greatly promote the future development of our mankind and the development of civilization.
