Venus's atmosphere is actually the future of the earth, which is irreversible. The main component of the atmosphere is carbon dioxide, which is the extreme case of the greenhouse effect. The earth is now developing towards the greenhouse effect, and the future will be like a golden atmosphere. Venus has many similarities with the earth. Venus has a radius of about 6,073 kilometers, which is 300 kilometers smaller than radius of the earth. Its volume is 0.88 times that of the earth and its mass is 4/5 of that of the earth. The average density is smaller than that of the earth. Venus' atmosphere may be related to the brightness and heat of the sun. It is generally believed that in the early days of the formation of the solar system, the atmosphere of Venus may be similar to that of the present Earth, with liquid water on its surface and good atmospheric conditions. At that time, the earth was still in a relatively cold era, so there was no life. After more than 654.38 billion years, the intensity of the sun gradually increased, and the temperature entered a suitable golden age. Unfortunately, there was no life. Later, with the improvement of the brightness of the sun, the surface water evaporated, and the greenhouse effect gradually formed and intensified, gradually becoming what it is today.
So Venus actually had a good atmosphere and surface water 4 billion years ago. Two billion years ago, the rising temperature and brightness of the sun caused the climate to get hotter, and water began to evaporate and run off. With the intensification of ocean evaporation 1 100 million years ago, greenhouse gases are becoming more and more serious. Until 600 million years ago, the ocean evaporated and the atmosphere was dominated by carbon dioxide. Venus's dense atmosphere is composed of 97% carbon dioxide, and there are dozens of kilometers of concentrated sulfuric acid clouds. Due to the greenhouse effect, the surface there remains close to 500 degrees Celsius, and there is no water in the atmosphere and on the surface. The ground pressure is more than 90 times that of the earth, with 65,438+10,000 even 1 10,000 volcanic lava, some of which flow for thousands of kilometers. Volcanoes there will not erupt. Due to the strong atmospheric pressure, magma has no water support.
In the solar system, Venus is the closest to the earth, which once gave people good expectations. But after the United States and the Soviet Union launched several probes in the last century, there was no hope at all. This is not a place to be alone at all. The special decompression corrosion strengthening detector works for 1 ~ 2 hours at most, which is damaged by high temperature and pressure and concentrated sulfuric acid. Therefore, it is only an unreachable dream for human beings to transform the atmosphere there and make use of Venus resources.
