They are also sister stars of the earth. Why are humans "eccentric" and only concerned about Mars?

As we all know, the earth is one of the eight planets in the solar system and the only living planet in the solar system. It has been 4.6 billion years since the birth of the earth. In this long development process, the ecological environment of the earth has also undergone tremendous changes. With the continuous development of global warming, the earth is getting hotter and hotter.

Hawking said in an interview with the media before his death that the future earth will become a fireball. Due to the rapid increase of population and the destruction of the earth's environment by human beings, the earth's environment will no longer be suitable for human survival in the future. If human beings want to develop in the long run, they can only emigrate to space.

According to scientists' monitoring, analysis and research on the earth's climate, there are indeed great problems in the earth's environment. At present, human beings have attached great importance to the development trend of the earth environment. At the same time, scientists are actively exploring outer space to find a second home for mankind.

According to the current ability of human beings, we can't realize interstellar migration, because human beings can't reach the speed of light, and they can't even fly out of the solar system, and at present they have only landed on the moon, so if you want to find a second home, you can only start from the planets in the solar system.

Of the planets in the solar system, only Venus and Mars are the most livable. Because these two planets, like the earth, are both terrestrial planets, and both are in the livable zone, Venus and Mars have become the exploration targets of scientists. But now Mars cares more than Venus. Why don't people pay attention to Venus? Is it a human quirk?

Actually, it's not like this. Although the environment of Venus and Mars is similar to that of the Earth, they were once called the Earth's? Sister star? But the environment of Venus is worse than that of Mars. In terms of size and mass, Venus is indeed very similar to Earth, while Mars is much smaller.

Although Venus has a thick atmosphere, these atmospheres are mainly composed of carbon dioxide, and the atmospheric pressure is about 92 times that of the earth, which is equivalent to the pressure of the earth's ocean at a depth of 1000 meters. Such an environment is doomed to human survival. Even the detector launched by human beings has many machine failures because it is difficult to adapt to the high-pressure environment of Venus.

Because the atmosphere of Venus is mainly carbon dioxide, the greenhouse effect of Venus is also very serious. Under the cover of the atmosphere, Venus receives less sunlight, most of which will be reflected back into space, and its thermal radiation reflectivity is about 60%.

If Venus had no greenhouse effect, its environment might be similar to that of the earth, but under the greenhouse effect, the surface temperature of Venus is very high, even at night, its temperature can reach 464℃, so it is almost impossible for Venus to survive in such a high temperature environment.

Venus also has no liquid water. Even if there is liquid water, it will be completely evaporated in such a high temperature environment. Moreover, there is a thick layer of concentrated sulfuric acid in the atmosphere of Venus, which is 20 ~ 30 kilometers thick. These thick clouds turn the sky of Venus into orange, and it often rains with acid rain, lightning and thunderstorms.

In contrast, the conditions of Mars are much better than those of Venus. Although the size and mass of Mars are not comparable to that of the Earth, it has four distinct seasons, and its self-axis inclination and rotation period are similar to those of the Earth. The average daily average of Mars is 24 hours, 39 minutes and 35.244 seconds.

Many people may say that Mars is a desert planet with drought and water shortage, but there is water on Mars. In 20 15, NASA announced that there is flowing water on Mars, and there are polar caps composed of water ice and dry ice at its poles, which will fluctuate with the seasons.

Besides,? Curiosity? When analyzing the rock samples of Mars, we found that phosphorus, nitrogen, hydrogen, oxygen and carbon are the key chemical components to support the existence of life, so Mars is far more livable than Venus, and Venus naturally faded out of people's sight.

Compared with Venus, the environment of Mars is a paradise. In order to immigrate to Mars, American Space Exploration Technology Company has also formulated a Mars immigration plan. However, if human beings want to survive on Mars, they need to release the atmosphere first, and Zuberlin has also made a plan. According to the plan, the frozen material of Mars should be completely melted, and at least the outer atmosphere of Mars should reach about 40℃ to make Mars warm.

With regard to the Mars migration plan, scientists are already in full swing, but this plan is still very difficult. I believe that the powerful scientific and technological strength of mankind will overcome these difficulties one by one. Maybe one day in the future, we will really realize our dream of moving to Mars. So what else do you want to say about this? Welcome everyone to leave a message in the comments section.
