How about interstellar migration to Mars?

The topic of interstellar migration has become more and more intense in recent years, because with the development of space industry in recent years, we have mastered manned space technology, which can be transmitted back and forth between Mars and the earth. We find that the environment and landform of Mars and the earth are similar, the temperature difference between day and night is smaller than that of Venus, the highest temperature is only about 25, and there is a small amount of atmosphere, which is within the scope of human transformation.

Planetary migration is an inevitable trend of human development into space, and it is also a signal of human March into the universe. In addition, with the trend of increasing human population every year, the earth is now carrying a large amount and the environment is destroyed, which further catalyzes the determination of human beings to immigrate to the planet.

As early as the early days of human exploration of the universe, space agencies in various countries have carried out various experiments on planet migration, simulating and restoring the living environment of immigrant planets one by one. Due to the immaturity of many technologies, coupled with human physical defects and weak adaptability, they experienced many failures and had to terminate the experiment. Until 2 1 century, the aerospace industry developed rapidly and NASA made a comeback again. This time it made preparations and made some targeted measures. Then, four men and four women were put into the experimental warehouse and lived successfully 100 days.

If you want to transform Mars, the stupidest way is to build a factory on the surface of Mars. Mars is much smaller than the earth, so there is no need to build many factories. The built factory can not only provide energy, but also emit a lot of halogenated hydrocarbons. Halogenated hydrocarbons, as greenhouse gases, are very strong and can be directly integrated into the Martian atmosphere. At this time, the atmosphere can also store the heat released by the sun, melt the frozen soil on the surface of Mars, and release liquid water to fill the dry river bed. Because greenhouse gases still raise the temperature of Mars, liquid water evaporates into water vapor and rises into the air, and the atmospheric pressure also rises, so that the atmospheric balance of Mars reaches a circular state, and continuous rainwater evaporates. Soon, Mars will become a human living environment similar to Earth.

Another method is to release perfluorocarbon directly into the atmosphere of Mars, which is also a strong greenhouse gas with low synthesis cost. It is directly synthesized from the components in the soil and air on Mars, and then thrown into the atmosphere for chemical reaction to release carbon dioxide, thus increasing the temperature of Mars. This method is also the most advocated by scientists because of its low composition and high efficiency.

If you really want to emigrate, you need to send a group of workers to do infrastructure construction in the process of transforming Mars. Because Mars is far away from the earth, it costs a lot to establish a colony, and manned spacecraft also need to fly back and forth hundreds of times to transport resources. In the early days, the colony had to choose an open and easy-to-develop site, and then use 3D printing technology to build a completely sealed ecosystem. It is also necessary to use Martian soil and rocks to build buildings to resist storms and radiation.

Robert, a famous astronaut and chairman of the Mars Association, once said that in 2 100, there is a great possibility that there will be millions of cities on Mars. It is reported that in 2030, a manned spacecraft will be launched to land on Mars to start infrastructure construction, and at the same time, it will begin to transform Mars and will continue to return in the next 20 years. It is estimated that by 2050, mankind will build a complete community on Mars with a population of about 1000. Expand the community scale in 2050-2070. At this time, the Martian environment has become more and more suitable for survival, and a large number of immigrants can be introduced for centralized construction. By 2 100, there will be an unprecedented mega-city on Mars with a total population of 1 10,000, which has completely occupied Mars and become our second home.

Migrating from Mars is a great challenge for the future human beings, but some scientists think that the migration at this time is a bit overwhelming and accompanied by great risks. Compared with other planets, Mars is indeed the most suitable planet for human migration, but there are still many unstable factors. Mars doesn't have the moon as a satellite like the earth, which can resist the impact of meteorites for us, so the probability of Mars being hit by meteorites is much higher than that of the earth. In addition, volcanoes on Mars are more active than those on Earth, accompanied by natural disasters such as earthquakes.

The most important thing is that human science and technology can't fully support us to immigrate to Mars at present. Even immigration, energy and cost are too high, and immigrants may get sick due to gravity and other factors (Mars medical care is not as developed as the earth).

Of course, it's only 2022. Think about the difference between the world 80 years ago and the present. It may be even more surprising to take today's rich technology as a stepping stone for the next 80 years.

Now, all countries are planning planetary migration, launching various probes to collect information on Mars, such as Tian Wen-1 in China and Mariner-4 in the United States. Planetary migration is indeed a great and arduous project, but human indomitable spirit will overcome many difficulties sooner or later. Perhaps in 2 100, there really appeared a million-level city on Mars. Finally, if the Great Migration of Mars really comes true, would you like to become an immigrant?
