Why do humans choose Mars to explore extraterrestrial life?

Human beings can obviously live well on earth, so why do they want to go "outside the earth" every day? There are just a few conventional reasons for it

First, to explore extraterrestrial life

Second, to search for extraterrestrial resources

Third, take a look Is it suitable for human habitation and to prepare for future human travel to extraterrestrial planets?

This is the most basic reason. Venus is indeed relatively close to our earth, but why is the whole world rushing to explore Mars? It’s not because the basic analysis results of Venus are not suitable for humans. Therefore, due to multiple factors, humans are unwilling to go to Venus. Compared with Mars, the cost of going to Venus may be much higher than Mars, so this is what humans do The "way of choice" is to abandon the near and seek the far, which is completely normal.

Venus

Venus is a special celestial body in the solar system. It is very similar in mass to the Earth, but the biggest difference is that this celestial body is a planet without a magnetic field. This is the It is a unique celestial body among them. Of course, the scientific community does not have a clear explanation for why this happens. At the same time, the detection of Venus is relatively difficult. This may be one of the reasons why humans are reluctant to go to Venus. It has a dense atmosphere and clouds. Only with the help of radio telescopes can we penetrate this atmosphere and see the true appearance of the surface of Venus.

According to the detection situation, the proportion of carbon dioxide in the atmosphere has reached more than 97%, so it is basically gray. At the same time, from the perspective of climate change, all detectors It may be easily corroded, and carbon dioxide can be transformed to form a large amount of acid rain, so this is a challenge for the detector.

At the same time, the surface temperature of Venus is also very high. The surface temperature is as high as 500°C, and the atmospheric pressure is about 90 times that of the Earth. There is no need for humans to go to such a celestial body, and there is absolutely nothing that can directly bring it to humans. It must be a difficult thing for humans to choose it as a habitable celestial body, so Venus has not become humans’ first choice for detection. Although it once had such a tendency, through research, it has been found that this celestial body The value does not meet one's own expectations, there is no oxygen, no water, it is even less likely to have life, etc., and the first choice issue is directly thrown away, this is the reason.

Mars

Mars is also called the "Second Earth" by humans because it is very similar to the Earth, and many scientific theories show that Mars was once the same planet as the Earth. Our Earth is very similar, but later on, Mars underwent a huge climate change, so it became what it is today. The atmosphere on the surface of Mars is not as dense as Venus, and is very thin. The main remaining atmosphere is carbon dioxide, accounting for 95.3%. However, Mars has another characteristic that is different from Venus, that is, it also contains oxygen and water vapor.

So this has become a key factor for human beings to explore other celestial bodies. With these, the ultimate goal of human beings - the hope of migrating to other celestial bodies is much greater. Why don't humans choose Venus? Because the basic conditions are too Worse, the hope of Mars is much greater once we see it, and judging from the current exploration situation, Mars is more and more likely to be suitable for human habitation, so the plan to colonize Mars is now being implemented on a large scale. , and scientists have discovered the existence of water on Mars.

With the emergence of water, the possibility of humans changing Mars will be greater, and the possibility of humans living on Mars in the future will be greater. This is why, after all, various conditions are gradually satisfying humans. The biggest difficulty now may be the problem of oxygen. If oxygen can be solved, then moving to Mars will really be just around the corner. So overall, although Mars is further away than the Earth, the conditions on Mars are much better than on Venus.

Summary:

From the above situation, we have indeed seen that Mars is a much better celestial body than Venus. If humans have the opportunity to immigrate in the future, then Mars will probably be the celestial body of humans. This is one of the reasons why humans now call it the "Second Earth" because compared to other celestial bodies in the solar system, this planet is really perfect. So there are inherent advantages.

This is the reason, including the fact that our country is also implementing the Mars plan on a large scale. Tianwen-1 is only the primary Mars project. In the future, our country will also implement Mars excavation, Mars base construction, Mars immigration, etc. question. So this is a global trend.
