When will we embark on a journey to immigrate to Mars? Why is there no information yet?

The Mars immigration plan initiated by the Dutch has attracted more than 50,000 people from all over the world to sign up. Finally, after strict selection, 100 people were selected. What makes this never-return immigration trip to Mars so attractive? This starts with Mars itself.

Mars is not special among the eight planets in the solar system, but from the perspective of breeding life, Mars’ advantage is that it has water. Due to the low temperature, water on Mars exists in the form of ice beneath the surface. If all this ice melted, the amount of water could cover the entire surface of Mars to a depth of 11 meters. Life is inseparable from water, and Mars obviously has the most basic conditions for sustaining life.

Human exploration of Mars began 50 years ago, and there are currently many experimental projects to observe and explore Mars. In this process, mankind's understanding of Mars continues to deepen. Scientists speculate that Mars billions of years ago was most likely much like the Earth today, with a thick atmosphere, water, oceans, and even life. However, because Mars' gravity is too weak, atmospheric molecules continue to escape, making Mars become as cold and dry as it is now, and ancient life also disappeared or was hidden underground. In addition, it has been confirmed that there is a small amount of methane in the atmosphere of Mars. Its source is still a mystery. It may come from chemical reactions or be produced by bacteria. If it is the latter, it is strong evidence for the existence of life on Mars.

Technically speaking, the biggest problem facing immigrants to Mars is not "traffic", but physical and psychological problems. Based on current aerospace technology, it takes about 8 months to fly from the Earth to Mars. The long journey will bring many problems to the immigrants, such as muscle atrophy and osteoporosis caused by weightlessness, and more radiation from cosmic rays. It may cause cancer and mental illness caused by living in a narrow space for a long time. In addition, even if we successfully reach Mars, how to establish a sustainable base will still be a challenge. Due to the limited number of immigrants, most labor depends on robots. In addition to cultivating food and exploring water sources, the most pressing issue is how to extract oxygen and ensure breathing.

So, should humans immigrate to Mars? The population of the earth is increasing, but the area of ??the earth will not increase. The best solution is to let some people immigrate to other planets. Looking at the solar system, Mars is obviously the first choice. There is another reason. Once the earth collides with another small planet one day and destroys mankind, just like the extinction of the dinosaurs 70 million years ago, then after the catastrophe, the incense of mankind may only be inherited by immigrants from Mars.

We have never discovered life on a planet other than Earth. If there is life on Mars, it is possible that Martian life is the descendant of life in warmer periods billions of years ago. Are their chemical and physiological genes the same as those on Earth? The origin period of life on Mars should be similar to that on Earth. After billions of years of fierce competition and evolution of life on Earth, the ancient primitive life has been eliminated. Due to changes in climate on Mars, evolution ceased but ancient life forms were preserved. This will be valuable information that Mars gives us to study the origin of life. Don't destroy this treasure before you master the method of discovering and protecting life on Mars.

In the long run, the search for habitable planets is a trend. Mars immigration is just the beginning. As far as this plan is concerned, there are still many problems to be solved.
