The rapid development of industry has brought continuous leaps in science and technology to mankind, not only making our quality of life higher and higher, but also allowing mankind to step out of the earth and begin to explore the universe. Everything has advantages and disadvantages. The rapid development of science and technology also has disadvantages, which is the continuous destruction of the earth’s ecology.
Today’s global environment and the pre-industrial ecological environment have undergone significant changes, and environmental degradation is getting more and more serious. Many scientists believe that the earth will no longer be suitable for human survival in the future. When the earth deteriorates to the point where it cannot adapt to the survival of human beings, if human civilization wants to continue, then it has to move out of the earth to the outer planet. So is it easy to migrate to outer planets? Of course it is not easy. There are a lot of dilemmas in this. The human body is very fragile in the cosmic environment and cannot sail for a long time.
Although there are countless galaxies and countless terrestrial planets in the universe, there are naturally many natural habitable planets for humans to live in. However, due to various restrictions, humans may only be able to find their second home in the solar system in the future. So is there a second habitable planet in the solar system? the answer is negative.
The solar system has three habitable planets, namely Venus, Earth and Mars. Only the earth is a natural habitable planet. The other two planets, one is the world of purgatory and the other is the desert world, are not suitable for human survival. Although the reality is cruel, human beings must also go out due to the deteriorating environment of the earth and some doomsday events that may occur in the future. They cannot put their eggs in a basket, otherwise they may be endangered.
Therefore, finding a second home for mankind in the solar system is what we must do. Although there is no second planet that is naturally suitable for human survival, scientists have discovered that Mars has many similarities with the earth. It may be possible through technological transformation. You can make it the second home of mankind. So can human beings survive on Mars for a long time?
Let’s take a look at the various data on Mars. Mars is one of the four terrestrial planets in the solar system and a red planet. The atmosphere of Mars is dominated by carbon dioxide, which is thin and cold, full of impact craters, canyons, sand dunes and gravel. There is no stable liquid water. This environment is somewhat similar to the deserts of the earth, so we also call Mars the desert world.
The atmospheric density of Mars is only about 1% of that of the Earth. It is very dry and low in temperature, with an average surface temperature of minus 55°C. Compared with the earth, the mass of Mars is much smaller, about one-ninth that of the earth, so the gravity of Mars is only 0.375 times that of the earth.
Such a Martian environment is naturally very harsh for humans, and we cannot survive on it. However, after decades of continuous exploration and research on Mars by the rover, scientists have discovered that ancient Mars a long time ago was not what it is now, but A beautiful ecological planet like the earth may have life.
The foundation of Mars is very good. It used to be an ecological planet. However, some changes happened later. The magnetic field was greatly weakened and almost disappeared, the atmosphere became very thin, and the liquid water on the surface basically disappeared, and it gradually became the current desolate. appearance.
With these relatively good basic conditions, the possibility of Mars being transformed successfully will be very high. With the continuous advancement of human science and technology, scientists are still full of hope for transforming Mars, and Mars is not without water now. There is still water in the north and south poles of Mars, and scientists speculate that there may still exist outside the surface of Mars. Reserves of water resources.
So when we successfully transform Mars and become a habitable planet, will humans be able to survive on Mars for a long time? It may also be very difficult, why is this? In fact, these are related to the foundation of Mars.
After introducing the environment of Mars earlier, we know that although Mars has a magnetic field, it is very weak and its atmosphere is very thin. I believe everyone knows the importance of magnetic fields to human beings. There are all kinds of high-energy particles in the universe. Radiation, whether it is solar radiation or other cosmic radiation, has a great impact on human beings.
The earth we live in has a strong magnetic field and a thick atmosphere, so it can effectively block the damage to the surface by these cosmic radiation and high-energy particles. However, the radiation energy on the surface of the moon is 400 times that of the earth, and the radiation on the surface of Mars is equivalent to two-thirds of the radiation on the surface of the moon. In such a high-radiation environment, human health will be affected.
In addition, the gravity of Mars is only about one-third of that of the earth, and the impact of such a gravity environment on humans is also obvious. We must know that the universe is in the microgravity environment of the universe. If you stay for a long time, your body will get sick. Human beings have lived in the earth’s environment for millions of years, and their genes have been imprinted on the earth’s ecological environment.
Once we leave this environment, our body will have problems. Therefore, the most suitable planet for human existence must be very similar to the earth’s environment. The basic conditions of Mars cannot meet these requirements. Of course, through the power of technology, we can change the structure of the Martian atmosphere, drastically reduce carbon dioxide and increase oxygen content, so that humans can breathe freely on the surface of Mars.
At the same time, we plant a large number of plants on Mars, which can also improve the desolate environment on the surface of Mars and make it a green planet step by step. But even if these changes, we cannot change the quality of Mars, it is difficult for us to increase the thickness of the atmosphere substantially, and it is difficult for us to strengthen the magnetic field of Mars. Because the size of Mars’ magnetic field is closely related to its inner core, unless we can enter the inner core and strengthen the movement of the inner core, to achieve such a goal, we need very strong scientific and technological strength.
Based on the above, it can be seen that even if Mars is successfully transformed by humans, it cannot become a permanent home. What’s more, the size of Mars is much smaller than that of the earth, and it can’t accommodate human beings with increasing population. Therefore, Mars is just an alternative temporary home for human beings. The real hope is in the outer galaxies.
The Milky Way has hundreds of billions of stars and trillions of planets, many of which are terrestrial planets similar to the Earth. It is not surprising that there are natural habitable planets that are almost close to the earth’s environment. Such planets are better homes for mankind. We must strive for this goal.
Of course, it is not an easy task to realize interstellar travel. Long interstellar travel has a great impact on the human body. If the problems of cosmic radiation and spacecraft gravity cannot be solved, then interstellar travel will be empty talk and cannot be realized at all. Of course, the power of science and technology is far from being poor, and as long as we work hard to develop, then every good wish can still be realized. Perhaps in the near future, humans will live happily on other planets in the outer galaxy, and we look forward to this arrival.
