The discovery of giant ice puddles on Mars by ESA is a step closer to the dream of human migration to Mars

With the rapid development of human science and technology, the consumption of the earth’s resources is accelerating. At the same time, various kinds of pollution caused by the rapid development of science and technology are also increasing. The emission of a large amount of industrial waste gas makes the temperature effect more and more severe, and the global temperature is also rising. Coupled with the pressure brought by the continuous increase of global man-made, scientists realize that human beings need to speed up the pace of exploring the universe, Find a second earth suitable for human survival.

The universe is vast and vast. There are hundreds of billions of stars and a large number of star clusters in a galaxy. Naturally, there are many earth like planets similar to the earth. By searching the sky within 1000 light-years, scientists have found hundreds of earth like planets similar to the earth, expanding to the whole galaxy. The number of such earth like planets will not be less than 1 billion.

Among so many planets similar to the earth, it is possible that there will be a new earth which is exactly the same as the earth and suitable for human survival. But such planets are all outside the solar system. The most recent ones are several light years, and the distant ones may reach thousands or tens of thousands of light years. With the current technology of human beings, the speed of spaceship is still very slow. We can’t even fly out of the small solar system. It’s impossible for us to explore or even migrate to the same planet as the earth, at least for a long time in the future.

Whether the current situation of the earth can wait until human beings have the ability to go to the places that are decades, hundreds, thousands of light years or more is also unknown. Therefore, scientists should focus on the solar system, find a rock star similar to the earth in the solar system, and then transform it to adapt to human survival.

The planets similar to earth in the habitable zone of the solar system are Venus and Mars. Although Venus is the Sister star of the earth and is closest to the rock structure and gravity of the earth, its surface temperature is as high as 400 degrees. Such a planet probe can not land at all, and there is almost no possibility of water. It is very difficult to transform such a purgatory planet.

In the end, only Mars is suitable for reconstruction. Although its surface environment is not good, the good thing is that the rover can land, so that more information about Mars can be obtained. Scientists explore Mars mainly to understand two factors, one is whether there is water, the other is whether there is life on Mars. Water is the source of life, human survival can not do without water, if Mars does not have water, it will be very difficult for human survival in the future.

The existence of Martian life is related to human health and life safety. If Martian life is a great threat to human health, it is necessary to find corresponding countermeasures to implement immigration, such as developing relevant vaccines and immunizing Martian viruses and bacteria. Is there water and life on Mars?

In fact, whether there is water on Mars is relatively easy to explore. The Mars orbiting probe can find some clues. In recent years, scientists have indeed found traces of water on Mars. Through the probe’s exploration of Mars, scientists have discovered that there are a lot of deltas, river beds and other landforms on the surface of Mars, which also implies that Mars will be in the future for a long time Period is a lot of liquid water, sea, sea berth.

NASA confirmed that Mars may have had the same thick atmosphere and ocean as the earth, and it was a green planet, possibly with Martian life and civilization. It’s just that I don’t know what happened later, which is what it is now. Since there are so many geomorphic features of water on the surface of Mars, will there still be liquid water on the surface of Mars?

On Christmas Eve, ESA’s Mars Orbiter took a picture of roliov crater, where it found a huge snow crater with a lot of water ice. The water ice is frozen. The crater, about 80.6 kilometers in diameter, is located south of the Olympian dunes in the northern part of Mars and about 1.6 kilometers deep. It is well preserved and full of ice all year round.

The permanent freezing state of a crater is caused by a phenomenon called “cold trap”, which means that when the air flows over its surface, it becomes cold and heavy, and “trapped” directly above the ice. This creates a cold air shield to keep the frost state. The water ice content in the crater is equivalent to that of the Great Bear Lake in northern Canada. If it melts completely, it can fill hundreds of Qinghai lakes.

The discovery of ice water in this huge crater has excited scientists. It also shows that there is a lot of water on Mars. Although the surface temperature is relatively low and liquid water does not exist, ice blocks like this huge crater exist. This is only the first huge ice block found now. Maybe there are other ice water on the surface of Mars.

There is such a huge amount of ice on the surface of Mars, which means that there may be a lot of liquid water under the surface of Mars, which is too important for human beings to transform Mars. As long as there is a lot of liquid water, the success rate of Mars transformation will be high. Water is not only the source of life, it is also the source of oxygen. The decomposition of water will release oxygen. With a large amount of water, plants can be planted. Plants will release oxygen and form a good circulation system. Gradually, Mars will become suitable for human survival and residence.

Some people may say that what we find now is only frozen water. How can we turn it into liquid water? We should know that the temperature on the surface of Mars does not support the existence of liquid water. In fact, this problem is not difficult to solve. The temperature on the surface of Mars is not extremely cold. As long as we can heat Mars, the frozen water will become liquid water, and there will be a lot of liquid water on the surface of Mars.

As for how to heat Mars, it was once proposed that huge solar panels should be installed in the orbit of Mars, and solar energy should be used to heat Mars. The theory of this method is feasible. This is not difficult for scientists, and water on Mars is the most important thing. This is the most exciting news from this year’s Mars exploration. The Mars Lander insight of the United States has landed on Mars, and is about to launch exploration and Research on the surface of Mars to determine the internal structure of Mars, as well as the existence of groundwater and Martian life.

It is believed that in the near future, scientists will launch a probe near the huge meteorite ice water crater to study the situation of the huge ice at a short distance and see if there is life in the ice water crater. Human beings know more and more about Mars, and will soon launch a manned landing on Mars, and human transformation of Mars will also be carried out. It is believed that in the near future, There will be human bases on Mars, and a group of people will migrate to live on Mars.
