Throughout the past and present, everyone likes to explore things because of their curiosity. Previously, Copernicus and once proposed the "heliocentric theory", which shocked everyone; later, Hawking proposed the evaporation of black holes, and the world was shocked again; there was also Wang Zhenyi observing the sky in the Qing Dynasty. All these show that human beings’ curiosity about the universe has continued to this day. There are also many ancient books that record celestial phenomena, but as Lu You’s poems wrote: "You can feel shallow on paper, absolutely knows that this matter must be practiced ", We have to pay our own practical actions.
Since ancient times, Chinese people have a beautiful yearning for the universe. The gold-inlaid pearl celestial globe , which is treasured in the Forbidden City, is a good example. We also have stories about the universe that have been passed down from generation to generation, such as Chang'e flying to the moon. In ancient times, people thought that Chang'e lived on the moon , there was a moon palace, and a jade rabbit. These are all people’s beautiful imaginations. People never thought about it. I will be able to land on the moon one day in the future.
As time goes by, the science and technology of various countries are also constantly moving forward. Through people's efforts, mankind has successfully landed on the moon and is further realizing the desire of mankind to explore the moon. From the exploration and research, we also found that the composition of the moon and the earth is completely different. The soil on the moon cannot be used for planting. There is no life on the moon, so why is it on the moon without life? There are hundreds of tons of garbage ?
Some netizens have also raised the question "Who threw it?" In the early days of technological development, my country was in a backward position, while the United States was very advanced. They were also the first country in the world to land on the moon, . In July 1967, Armstrong landed on the moon as an American astronaut. This was not only the first time in the United States, but also the first time in human history. Since the United States, various countries have begun to accelerate their own scientific research processes.
However, landing on the moon is not a matter of saying that success can be achieved. Therefore, many countries have not yet realized their desire to land on the moon due to their own economic conditions and other reasons. Globally, has so far only three countries have landed on the moon, and my country is one of them.
Through years of scientific and technological research and unremitting efforts, China has brought the country’s aerospace industry to the height of a “powerful country”. With the successful launch of the " Chang'e-5 ", which has brought my country into a mature field for exploring the moon, has improved my country's international status, which is also the so-called technological power . my country's exploration also provides more effective information for studying the moon.
Of course, we mentioned earlier that various countries are actively exploring the moon, which will inevitably bring some damage to the moon. No matter which country it is in, the lunar probe is made of metal materials when it is manufactured, which is difficult to be physically degraded . Before we explore the moon, we must do a series of analyses, and develop the probe based on the four characteristics of the moon: " high vacuum, high cleanliness, weak gravity, and weak magnetic field ".
However, because the level of science and technology in many countries of is not up to standard, the detectors developed cannot meet the standards for landing on the moon. Therefore, many detectors that crashed due to unsuccessful detection are left on the moon. These metals The equipment cannot be taken away with our existing human technology. The weight of these detectors is also quite large, which led to the current moon with about 187 tons of garbage.
But we all have to believe in the development of science and technology, and mankind will surely be able to realize the wish of taking away these metal garbage from the moon in the near future. But now some people think, why are human beings so persistent in exploring the moon? To put it simply, people want to find a place suitable for human existence outside the earth .
The climate has become bad, and the earth's resources are constantly being developed by people , which is one of the reasons why mankind explores the universe ; secondly, mankind also wants to find more applicable resources. And because the distance of the moon is the nearest to the earth, the moon has become the first object of detection.
The wishes of human beings are all beautiful, but we also have to look at these “desires” from a dialectical perspective. There is a poem in ancient times that “looks like ridges and peaks, with different distances and heights”. Two-sidedness. It is like humans exploring the moon. The good thing is to broaden the field of human exploration and increase the scientific research results of human beings; but the bad thing is that our human explorations put an unloaded burden on the moon. ", bringing it a lot of metal garbage.
It is a very good thing for human beings to be curious about the world and the universe. The famous astronomer Copernicus also said: "The nature of human beings is the exploration of the unknown world." It is precisely because of this that I hope to be able to In the future, humans can develop materials that can be degraded for the moon, and even materials that can be degraded for other planets. Human beings have strong creativity and exploratory power. I believe that this day will not be too far away.
