What would happen if Mars was fitted with an artificial magnetosphere?

For millions of years, the earth has been the home of mankind. For this beautiful home, human beings naturally hope to survive forever. However, the development of reality makes people see that the earth is coming to the end step by step, and the root of all this is actually caused by human activities.

In fact, the activities after the birth of human beings have been destroying the earth's ecological environment, but in ancient times, because the number of human beings was still relatively small, there was no technology and industry at that time, and the damage of nature to the earth's ecology was not obvious. However, as mankind entered the era of science and technology hundreds of years ago, the development of a large number of industries accelerated this destruction.

Human science and technology have developed rapidly in the past hundred years, and the deterioration of the environment is also accelerating. I believe everyone can clearly feel that the earth is dying step by step from the increasing natural disasters and rising global temperature in recent years, and there is no way for human beings to stop this process of aging and death. The reason is simple, because we can't stop all industries and abandon technology to stop the deterioration of the ecology.

If the deterioration of the earth's ecological environment cannot be stopped, what should future human beings do? The only way that scientists can think of is to emigrate to other planets. Therefore, after mankind walked out of the earth, it has been actively exploring to find a new earth suitable for human survival. Although there are many natural planets that may be suitable for human survival in the vast universe outside the solar system, we may not be able to realize interstellar migration for a long time in the future because of the distance and the speed of human science and technology development.

Therefore, in the future, scientists can only focus on the planets in the solar system. At this time, Mars has entered the field of vision of scientists. Mars is a neighbor of the earth, which has many similarities with the earth and is on the edge of the livable zone. In order to explore Mars, scientists have sent dozens of probes to Mars. Through the exploration of these probes for more than half a century, we have learned enough about Mars.

Through these understandings, we know that Mars is a desolate planet with a very thin atmosphere and no magnetic field. Through the latest exploration in recent years, scientists have discovered an ancient river bed on Mars, indicating that there was an ocean on Mars, and the detector also found the existence of methane on Mars, which made many scientists think that there may still be life on Mars.

There is no liquid water on the surface of Mars. In fact, there is a lot of solid ice in the North Pole of Mars, and there may be liquid water under the surface of Mars. Through these understandings of Mars, it tells us that the ecological environment of Mars is no longer suitable for human survival, so how can human beings complete their migration to Mars in the future?

If we want human beings to immigrate to Mars in the future, we need to transform Mars into a planet suitable for human survival. To make the environment of Mars change greatly and become a planet suitable for human survival, there is an important premise, that is, there must be a strong magnetic field. Scientists speculate that Mars had a magnetic field long ago. At that time, Mars also had a thick atmosphere, a liquid ocean on its surface and possibly life.

Just don't know why, because the iron core inside the Martian core doesn't work, the Martian magnetic field fails. About 90% of the Martian atmosphere is blown away by charged particles in the solar wind at a speed of 250-750 kilometers per second. Without the protection of magnetic field and thick atmosphere, a large amount of liquid water on the surface of Mars has also been kidnapped by the solar wind, and only a few may freeze under the surface below the North Pole.

The human ecological environment can not be separated from the protection of magnetic field and thick atmosphere, in which magnetic field plays a key role. Without the protection of magnetic field, it is hard not to lose the atmosphere. Moreover, another key function of magnetic field is to effectively block solar radiation and cosmic radiation. Although human beings are intelligent beings, their resistance to all kinds of cosmic radiation is very weak.

Therefore, if Mars wants to become a livable place for human beings, it must first have a strong magnetic field to protect us from all kinds of cosmic radiation. However, the core of Mars has stopped running and the natural magnetic field has disappeared. If humans want to make Mars have another magnetic field, they can only create an artificial magnetic field through the power of science and technology, that is, install an artificial magnetosphere in the orbit outside Mars.

Some people may think that the role of artificial magnetic field is to prevent the invasion of cosmic rays, but in fact, the role of artificial magnetic field is far beyond our imagination. If we put an artificial magnetic field on Mars, it will bring unexpected great changes to the ecological environment of Mars.

First of all, after Mars has an artificial magnetosphere, the stripping of the Martian atmosphere by the solar wind will be greatly reduced, and the Martian atmosphere will not be lost again, but will gradually become thicker. At this time, the atmospheric pressure of Mars will increase with time, and the increase of atmospheric pressure will further increase the temperature.

When the temperature of Mars rises, the solid carbon dioxide covering the North Pole of Mars will be released. At the same time, solid ice will also become flowing water, which will produce greenhouse gases in the atmosphere over time. At this time, Mars is basically close to the ecological environment of the earth and suitable for human survival.

This shows how important the artificial magnetosphere is to the change of the ecological environment of Mars. With it, the ecological environment of Mars will change greatly, and the temperature of Mars will gradually get warmer. If we want to speed up the temperature rise of Mars environment, maybe we can put an artificial sun in the orbit of Mars after human beings realize controlled nuclear fusion technology in the future. Combining with the artificial magnetosphere, we can transform Mars more quickly and make it a livable place for human beings, so that human beings can immigrate to Mars.

These ideas are all beautiful, but neither artificial magnetosphere nor controlled nuclear fusion technology can be realized by human science and technology. The artificial magnetosphere, in particular, is a whimsical idea to many people now, but the power of science and technology is infinite, which can make the impossible possible.

Although there is no way for humans to transform Mars into a livable place, it is not difficult to transform the environment of a planet in the future. If humans have the technology to transform the environment, we can not only transform Mars, but also transform planets such as Venus. Even we can reshape the earth's ecology and make it more beautiful, so that the earth will not perish and human beings can survive forever.
