In 2100, "million-level cities" will appear on Mars. Will humans transform and immigrate to Mars? -

The topic of interstellar immigration has become more and more intense in recent years. This is because with the development of the aerospace industry in recent years, we have mastered manned space technology and can transmit back and forth between Mars and the Earth. It was also found that the environment and landforms of Mars are similar to those of Earth. The temperature difference between day and night is smaller than that of Venus. The maximum temperature is only about 25°C. There is also a small amount of atmosphere, which is within the scope of human transformation capabilities.

Planetary immigration is an inevitable trend for human beings to develop into space, and it is also a signal for human beings to march into the universe. In addition, with the annual growth trend of human population, the earth is now bearing a heavy load, and the environment is destroyed, which further catalyzes human beings' determination to immigrate to the interstellar world.

As early as the early days of human exploration of the universe, space agencies of various countries have conducted various experiments on planetary immigration, simulating and restoring the living environment of the immigrant planet one-to-one. Due to the immaturity of many technologies, Due to human physical defects and weak adaptability, the experiment had to be terminated after many failures. Until the 21st century, the aerospace industry developed rapidly, and NASA made a comeback again. This time it was well prepared and took some targeted measures. Then, four men and four women were placed in the test chamber and lived successfully for more than 100 days.

The stupidest way to transform Mars is to build factories on the surface of Mars. Mars is much smaller than the earth, so the number of factories required does not need to be built very much. The factories established can not only provide the most energy The important thing is that a large amount of halocarbons will be emitted. Halocarbons are very strong greenhouse gases and can be directly integrated into the atmosphere of Mars. At this time, the atmosphere can also store the heat released by the sun, allowing the permafrost on the surface of Mars to thaw, releasing liquid water to fill the dry riverbed. Since greenhouse gases still increase the temperature of Mars, liquid water evaporates into water vapor and rises into the air, and the atmospheric pressure also rises. This allows the balance of the Martian atmosphere to reach a cyclic state, and it rains continuously and evaporates. Soon Mars becomes Earth-like environment for human survival.

Another method is to directly release perfluorocarbons into the Martian atmosphere. It is also a strong greenhouse gas, and its synthesis cost is low. It directly uses components in the soil and air on Mars. After synthesis, it is thrown into the atmosphere to undergo a chemical reaction to release carbon dioxide, thereby increasing the temperature of Mars. This method is also the most advocated by scientists because it has low ingredients and high efficiency.

If you really want to immigrate, you will need to send a group of workers to do infrastructure construction during the process of transforming Mars. Since Mars is far away from the earth, it will cost a lot to establish a colony. Human spacecraft also need to fly back and forth hundreds or thousands of times to transport resources. In the early stage, the colony must choose an open and easy-to-develop location, and then use 3D printing technology to create a fully sealed ecosystem. It also needs to use Martian soil and rocks to build buildings to withstand storms and radiation.

Robert, the famous astronomer and president of the Mars Society, once said that it is very likely that there will be million-level cities on Mars in 2100. It is reported that a manned spacecraft will be launched to land on Mars in 2030 to start infrastructure construction. At the same time, it will also begin to transform Mars. It will continue to come and go in the next 20 years. It is expected that by 2050, humans will have built a complete community on Mars with a population of one thousand people. about. The scale of the community will be expanded from 2050 to 2070. At this time, the Martian environment has become suitable for survival, and a large number of immigrants can be introduced for centralized construction. By 2100, unprecedented giant cities will appear on Mars, with a total population of 1 million. Mars has been completely occupied and has become our second home.

Mars immigration is a huge challenge for mankind in the future, but some scientists believe that immigration at this time is a bit inadequate and comes with huge risks. Compared with other planets, Mars is indeed the most suitable planet for human immigration, but There are still many unstable factors. Mars does not have a moon as a satellite like Earth, which can protect us from meteorite impacts, so the probability of Mars being hit by meteorites is much higher than that of Earth. In addition, the volcanoes on Mars are more active than those on Earth, and are also accompanied by earthquakes. Wait for natural disasters, etc.

The most important point is that humankind’s current technology cannot fully support our immigration to Mars. Even if we immigrate, the energy and cost will be too high, and the immigrants may not adapt to the Martian environment due to gravity and other factors. And thus get sick (medical treatment on Mars is not as developed as on Earth).

Of course, it is only 2022. Think about how different the world was 80 years ago from now. In the next 80 years, with today's strong technology as a stepping stone, it may be even more surprising to develop. .

Today, all countries are planning for planetary immigration and have launched various probes to Mars to collect information, such as my country's Tianwen-1, the United States' Mariner 4, and so on.

Planet immigration is indeed a great and difficult project, but the tenacious spirit of mankind will overcome many difficulties sooner or later. Perhaps a million-level city will really appear on Mars in 2100.

Finally, if Mars immigration really comes true, would you be willing to be an immigrant?
