Sample studio

The main purpose of collecting soil samples on the moon is to speculate on the evolution history of the moon and prepare for the earth to collect a large number of lunar resources, which will also become an important foundation for starcraft in the future.

(1) Chang 'e V

The mission of Chang 'e V is to collect dust and debris from the unexplored area on the front of the moon and send them back to Earth. Lunar scientists can't wait to study new samples because they can understand the evolution of the moon. These substances can also help researchers more accurately determine the age of the surfaces of planets such as Mars and Mercury. ? The choice of landing site is extremely wise. ? Harald Hiesinger, a geologist at the University of Mü nster, said.

Scholars believe that the Chang 'e-5 sample can fill an important gap in scientists' understanding of lunar volcanic activity. The rocks obtained by the United States and the former Soviet Union in previous missions to the moon show that volcanic activity on the moon reached its peak 3.5 billion years ago, and then weakened and stopped. However, the observation on the surface of the moon found that some areas may contain volcanic lava, which was formed 65.438 billion to 2 billion years ago. If the samples of Chang 'e V confirm that the moon is still active during this period, it will rewrite the history of the moon.

(2) Significance

In fact, if Chang 'e V is successfully launched, it will bring us the following benefits.

First, China ranks among the world's space powers. You know, countries that have made plans to land on the moon include the United States, India, Israel, Japan and so on. Among them, the United States successfully achieved the feat of sending an overloaded man to the moon, which is considered to be a big step for mankind to enter space. But the manned landing on the moon in the United States has always been considered? Scenes shot in Hollywood studios? . So America needs to return to the moon to prove its ability. However, due to the epidemic, the US space program may have to be shelved. In the past two years, Israel and India have launched their own lunar probes, but both failed. Japan's moon landing plan is still in preparation and may be shelved due to insufficient funds. China has full technical and financial support. Once China successfully launches Chang 'e V, it will surely become one of the world's space powers. Second, show China's comprehensive national strength, enhance our national self-confidence and cohesion, and enhance our right to speak in the world. Aerospace science and technology is a demonstration of a country's comprehensive strength in science, technology, military and economy. China has continuously completed the development of Chang 'e series detectors without any accident, which fully shows that China's comprehensive national strength has been qualitatively improved. At the same time, this move will greatly enhance the self-confidence and cohesion of the Chinese nation. And China's voice in the world will be improved accordingly. Third, lay a foundation for the future immigration of our country and mankind. You know, during the cold war, the United States and the Soviet Union each collected some small soil samples from the moon. This is of great scientific value to the study of lunar resources. Experts pointed out that at present, the earth's resources are increasingly exhausted, and the helium -3 on the moon can meet the energy demand of human beings for about 6.5438+0 million years after being used for nuclear fusion power generation. If Chang 'e V brings back samples, it will not only rewrite the history of the moon, but also lay the foundation for human migration to the moon.
