Is it really possible for humans to move to Mars, or is it just a concept?

Humans want to immigrate to Mars. It is simply impossible to achieve with current technology. It’s not that people can’t immigrate to Mars. It's because a large number of human immigrants cannot survive well on Mars. 1. The temperature is too low for human survival.

The first problem in immigrating to Mars is temperature. The average temperature on Mars is minus 73 degrees, and temperatures of more than minus 70 degrees are not suitable for human survival at all. Unless you wear thick cotton clothes at all times and require a lot of energy to heat. The reason why the temperature of Mars is much lower than that of Earth is because the atmosphere of Mars is thinner than that of Earth. No heat remains in the atmosphere, so temperatures are extremely low. There are many ways to deal with low temperatures. Scientists once thought about using an oversized magnifying glass to partially amplify sunlight. Shining on the surface of Mars. This will make the temperature on the surface of Mars temporarily suitable for human survival. Although this method is theoretically possible, it is currently just a theory. ?2. The oxygen concentration is not enough.

Another problem that prevents people from moving to Mars is oxygen. Oxygen is one of the essential substances for human survival. If you want to immigrate for a long time, people will not take oxygen tanks to Mars like astronauts. Because in that case, it would not be a real immigrant. In that case, the government would have to launch a large number of rockets at intervals to transport oxygen. This would not solve the fundamental problem of immigration at all, but later scientists discovered that there are glaciers on Mars. If you create a nuclear explosion, you can melt the permafrost and glaciers on Mars and release water and carbon dioxide. Using existing technology, water and carbon dioxide are used to grow plants in greenhouses. In this way, people and plants can form a simple ecosystem to achieve the purpose of survival. three. Immigration to Mars is not yet achievable with current technology.

With the current technology of mankind, it is still very difficult to move to Mars. First, we want to transport a large number of humans to Mars. The cost of building spacecraft will be prohibitive. Moreover, a series of cultural construction after immigrating to Mars will also consume a lot of manpower and material resources. The most important thing is that with current technology, it cannot be completely safe. Therefore, it is still a concept for humans to immigrate to Mars, but I believe that in the future, humans will be able to realize their dream of immigrating to Mars.
