Mars immigrants pick up the phone.

Mars is the "neighbor" of the earth and the planet with the most similar topography in the solar system. It is considered to be the most valuable planet for exploration and development in the solar system. In recent years, all the space powers are keen to explore Mars. Just before and after the Spring Festival, the "Hope" from the United Arab Emirates, the "Tian Wen No.1" from China and the "Persistence" from the United States have successively reached the orbit of Mars, and the "Persistence" from the United States has landed on the surface of Mars.

At present, what humans can do to Mars is to launch some unmanned probes, and the United States has done the most in this regard. However, Musk, a technology madman, obviously didn't notice these things. As many friends may know, Musk said that one million people immigrated to Mars. This statement was made on 20 15, which means that he will immigrate to Mars by 6.5438+0 million people in 2030 (later, he said that he will immigrate to Mars/kloc-0.0 million people six years later).

In any case, Musk is a respectable person. He started in many frontier fields of science and technology, and most of them have achieved great success. He boasted a lot of cows, but most of them came true. No one in the world can compare with him. But even so, his words about emigrating to Mars in 2030 are still too watery, as big as the Pacific Ocean! It can be said that the cow he boasted about was impossible before 2030. Even if we give him another 30 years, it will be impossible by 2060!

Why do you say that? First of all, we must know that humans have not even landed on Mars, and it is estimated that the world's major space powers will still be unable to land on Mars within 10 years. Although Musk believes that his generals will be ahead of the world's space powers, manned landing on Mars still needs a lot of money, and his starship plan is not smooth sailing. Starship 8 and Starship 9 both failed and were damaged during the test, and although they have been tested for 9 times, the starship still has not broken through the earth's atmosphere, and the highest is only about 20 kilometers from the ground. The closest time for Mars to the earth is also 5. It takes seven months to fly to Mars at a distance of five million kilometers, which requires not only enough rocket thrust, but also the safety guarantee and daily life supply of pilots, various support facilities and technical reserves, all of which take time to complete. Therefore, after 10 years, even before 2030, it is basically impossible for 1 10,000 people to immigrate to Mars.

But recently, Musk changed his mind and thought that the goal of manned flight to Mars should be started before 2026, which shows that he doesn't believe in his bragging cows.

Recently, however, another American boasted that "a city with a population of one million will be built on Mars within 80 years". According to the report of Sputnik News Agency & Radio on February 2 1 day, Robert Zublin, president and engineer of the American Mars Society, believes that human beings can live on Mars before 2030, and a big city with a population of one million will appear 2 100 years ago.

Zublin supports Musk's Mars immigration plan, saying that "it may be by 2030. In 2026 or 2028, starships carrying goods or robotic missions can be transported to Mars and begin to automatically establish bases. " He believes that the first batch of 1000 people can immigrate to Mars, but before they can be transported there, they need power plants and systems to produce fuel from Martian oxygen and water. When humans arrive on Mars, they can carry out industrial and agricultural production on Mars, thus having the opportunity to support more people's activities, and then they can continuously send volunteers to Mars, but basically they will never come back. They will reproduce and produce on Mars, making more and more people on Mars. The city will be built before 2070, and it will develop into a big city with a population of one million by 2 100.

The future that Zublin said will come true, but the time will definitely be pushed back for several years. It is also unrealistic to say that a city with a certain scale will be built on Mars in 50 years for human life. Americans landed on the moon 52 years ago 1969. At that time, many scientists predicted that there would be human cities on the moon in 50 years. However, more than 50 years later, only a few people in the United States landed on the moon.

Why don't Americans go to the moon anymore? The most important point is that it is uneconomical, and landing on the moon is of little practical significance. There is still enough room for human survival and development on the earth. In such a realistic situation, the plan of landing on the moon or even boarding the fire is not important or urgent, just for scientific exploration and research, and there is no need to carry out the immigration activities of millions of people. Therefore, it is predicted that in the next 100 year, there will be no large-scale migration plan for Mars, but more than 65,438.

In addition, in the future 100, Martian immigrants will still face the bottleneck of technology and Martian resources. First of all, the Mars spacecraft will carry dozens of people and carry enough necessities to supply these people for at least seven months, so the payload of the rocket will be several times larger than that of Saturn V. Such a spaceship is only in the imagination at present, and the starship that Musk is building does not have such capability, and moreover, it's not possible to build such a spaceship.59980.999999998965

Compared with transportation technology, the resources on Mars are a bigger problem. We all know that the atmosphere of Mars is very thin, and the surface pressure is not as high as 1% of the earth's surface pressure. Moreover, the atmospheric composition is mainly carbon dioxide, and there is no liquid water on Mars. How do humans survive on Mars? Even if we can build a closed base, fill it with oxygen, bring water, plant green plants in it, and create an ecological environment similar to the earth's surface by photosynthesis, how much closed base, oxygen and water resources are needed, and how many green plants are needed to supply human beings with a population of one million to survive in it? At present, this is unthinkable!

Therefore, although it is almost certain that humans will immigrate to Mars in the future and build Mars cities, it is impossible before 2 100. So when do you think it will be realized? Welcome to express your opinion below.
