Why explore the new world of Mars? What's on Mars?

The recent successful landing of the Zhu Rong rover has aroused people's interest in Mars, but people must be curious. There are many planets in the solar system. Why do we have high hopes for Mars? Besides the distance between Mars and us, the more important reason is that Mars is almost another earth, or a lifeless earth.

About 4.6 billion years ago, the gravity of the sun attracted countless dust and rocky planets in the universe. They collided and attracted each other, and gradually formed the most primitive planet in the solar system. Earth and Mars were born almost at the same time, and the location conditions are the closest. On 20 15, the research team of NASA gave us a better understanding of Mars. In July, hydrated salt was found on Mars, which confirmed the existence of liquid water on Mars, which is the key to life. Later, it was found that there may have been a lake that lasted for 10 thousand years before Mars, and the atmosphere of Mars was blown away by the solar wind.

So is there really life on Mars? Some people say it may exist, and there may be liquid water on Mars. Liquid water is the key evidence of the existence of life, and some people say it is impossible, because hydrated salt is not real liquid water, and Mars has no atmospheric conditions suitable for biological respiration, and its temperature is relatively low.

If liquid water really exists on Mars, water is an important factor to breed life, which makes it possible for Mars to breed many kinds of life like the Earth. In fact, if we look closely, we can also see the similarities between Mars and the earth, such as the typical rope-like lava phenomenon after magma flows, which is caused by the gradual cooling of magma during the flow. This phenomenon can be seen near many volcanoes on earth. There is such a terrain on the surface of Mars. In addition to rope lava, a large number of lava tubes also left traces on Mars.

In our eyes, volcanic eruption seems to be a series of disasters. On an inanimate planet, volcanic eruption often means that new changes are about to begin. Magma has not only brought about changes in topography, but also brought various rare elements to the ground, bringing new possibilities to the whole earth. Of course, the most important thing is that a large number of water vapor and dust explode together and float to the whole planet in the form of gas, which also brings the most important thing in life-rain.

Rain brings more than just water. After the rain falls, it will slowly converge into a river with the terrain, and the river has become a new force. It not only dramatically changes the terrain, but also constantly dissolves some minerals and recombines iron-containing mineral nodules like blueberries, which are called Martian blueberries. This is considered by many scholars as the key evidence that there was running water on Mars.

Everything is confirming that Mars can at least have life, but why did Mars become what it is today? Maybe the temperature in the inner core of Mars is not enough, or maybe an impact disturbed the core. The magnetic field of Mars gradually disappears, and the solar wind can directly affect Mars. The atmosphere eventually accumulated by Mars was destroyed, and volcanic activity gradually became inactive. The atmosphere and surface water are not replenished, and the good environment that has been accumulated hard has disappeared.

The air pressure and temperature dropped rapidly, but fortunately, with the drop of temperature, some liquid water was stored near the poles and underground, and even carbon dioxide was frozen at low temperature, forming a unique dry ice mat. Although it looks spectacular, without the flow of water and the protection of the atmosphere, even if life does appear on Mars, it will soon disappear and become a piece of dust in such a harsh environment. This makes Mars a dead planet, but on a barren planet, some magnificent landforms have been preserved, just like a history book, recording the scenes that happened on Mars.

But if it's just to understand this, why should we explore Mars so diligently? What's in it for us? I need to know more about Mars. The atmosphere of Mars is very thin. Even below 1% of the atmospheric pressure at the earth's sea level, there is almost no free oxygen. In addition, the weak magnetic field completely exposes Mars to the solar wind. Therefore, although the environmental position is similar to that of the earth, it is almost impossible to transform a planet like the earth, so it is unrealistic to relieve the current pressure by immigrating to Mars.

Moreover, as the twin sister of the earth, the resources of Mars are not necessarily so scarce, because many scarce resources are caused by insufficient technology and productivity, and it is not necessary to transport resources from Mars to meet our needs. And in the stage of launching rockets with chemical energy, the cost may be really too high. To sum up, the real meaning of exploring Mars can be summed up in five words-exploring new possibilities.

At present, Mars really can't bring us good economic benefits. We may not even know what the exploration of Mars can bring us, but the first man who walked upright certainly didn't think that human beings could evolve to such a degree. What she had to do at the beginning might just be to see further. Similarly, at the beginning of the invention of electricity, no one thought that it could change the world. They were just curious at that time, so we may not be as good as crawling apes in the vast universe now, so why give up exploration?

If a country can't even protect itself, it will naturally not pursue new possibilities, but I believe that anyone will be excited when they hear the word "exploring the universe", so exploring Mars itself is its meaning. If we live on a warm earth, no matter how many years we spend, we are just a dust in the stars. Therefore, exploring the universe is not only the embodiment of a country's strength, but also the embodiment of a country shouldering human destiny. After all, I am Liang Qiang. Thank you for your concern and support.
