How to form a large amount of oxygen on Mars, and what conditions are needed?

In recent years, with the serious destruction of the ecological environment on the earth, various resources on the earth are gradually exhausted due to over-exploitation. On the one hand, human beings have begun to intensify efforts to protect the environment, on the other hand, they are also stepping up efforts to realize human interstellar migration as soon as possible, so that human beings can leave the earth as soon as possible and go to a temporary new home.

At present, due to the limitation of human flight speed, human beings can't go too far, so they can only set the first stop in human space as Mars. Mars, like the earth, is in the livable zone of the solar system, but its environment is very different from the earth. For human beings, if they want to survive, the necessary conditions are oxygen, water and suitable temperature, but Mars does not meet these three points at present.

However, scientists have made plans to transform Mars, and the whole plan will take about 200 years to turn Mars into another earth step by step. The first thing to be solved is the atmosphere. Although Mars has an atmosphere, it is very thin. Therefore, scientists planned to build hundreds of nuclear reactors on the surface of Mars from the beginning, and continuously emit fluorocarbon into the atmosphere of Mars through combustion. In this way, Mars only needs about 65,438+000 years to have a thick atmosphere.

The second step is to do it on Mars? Artificial rainfall? Let Mars have lakes and oceans, so that when the temperature of Mars becomes suitable, green plants will be planted on Mars. After about 50 to 100 years, Mars will gradually have enough oxygen and may become our new home. By then, humans can also March on Mars on a large scale and successfully start a new life on it.

At present, scientists have found a new way to transform the temperature of Mars, that is, through the greenhouse effect of silica aerogel on Mars, so that the temperature of Mars can be transformed into a temperature suitable for human habitation. What is silica aerogel? Simply put, this is a new material with great scientific research prospect, which can provide warm temperature for a long time in areas with very little energy supply.

This is because silica aerogel belongs to porous structure, and light can freely shuttle through it. For human beings, after landing on Mars in the future, a warm environment can be formed on the surface of Mars only by putting silica aerogels on the surface or underground. Generally speaking, the temperature of the earth can be reached as long as it is not in the extremely cold zone on Mars. And because of temperature, there is liquid water on Mars.

In fact, in earlier scientists' plans for the transformation of Mars, when there was oxygen on Mars, the basic ecological environment had been built, and life was probably born on Mars itself, just like the early earth. This time, building an ecological circle on the surface of Mars through silica aerogel will enable human beings to immigrate to Mars as soon as possible. However, there is one problem. Mars is not big. If the biosphere on Mars is divided by artificial means, many people on the earth will not be able to immigrate to Mars. What should they do?
