Which is more suitable to be the first permanent alien colony of mankind, Mars or the moon?

Mars and the moon are both likely to become permanent alien colonies for human beings. Because they are closest to the moon, the moon will be the first permanent alien colony for human beings.

? ? 2022 is an extraordinary year. After China's Chang 'e V successfully brought back 173 1 g lunar soil from the moon, scientists found mineral elements that can be used to make oxygen and rocket fuel, which means that if a permanent base is established on the moon, local materials can be taken from the moon and these minerals can be directly exploited to make rocket fuel and synthetic oxygen. Prepare for the next exploration of the depth of the universe, and the gravity of the moon is obviously smaller than that of the earth. If a rocket is launched from the moon to explore the universe, the kinetic energy required is far less than the energy consumed by launching a rocket on the earth.

It is precisely because of these advantages that the moon will become a springboard for mankind to explore the universe, and it will also become the first permanent colony of mankind in outer space. The reason is that the moon has several advantages.

First, gravity is lower than that of the earth.

The moon is the natural satellite of the earth and the fifth largest satellite in the Milky Way. Much smaller than the earth, gravity 1.622m/s? Of course, just looking at this data, many friends will feel very abstract. In fact, intuitively speaking, the gravity of the moon is one-sixth of that of the earth. That is to say, if it takes six tons of fuel to launch a rocket from the earth and enter space, it only takes one ton of fuel to launch a rocket from the moon and escape from the moon's gravity.

Therefore, it is most appropriate to use the moon as a springboard for human beings to explore the universe. The gravity of the moon itself is less than that of the earth, which saves fuel for rocket launch.

Second, there are minerals that synthesize oxygen and make rocket fuel.

Chang 'e V found a large number of compounds such as helium, iron and titanium in the lunar soil brought back from the moon, which can be used as catalysts. By using these catalysts, combined with the action of sunlight, water can be converted into oxygen and hydrogen, and then carbon dioxide and hydrogen react chemically to produce methane and hydrogen, which can be used as rocket fuel.

Solving the problem of oxygen and fuel on the moon will provide more convenience for human beings to explore the universe, and there is no need to transport fuel and oxygen from the earth to the moon, so the moon is the most suitable permanent base for exploring the universe.

Third, the planet closest to the earth.

The moon is the closest planet to the earth. Helium, iron, titanium and other compounds that can synthesize oxygen and water and can be used as energy sources have been found on the moon, which means that the moon has the conditions to become the permanent base of mankind.

After talking about the moon, let's talk about Mars. First of all, the surface area of Mars is about 28.4% of that of the Earth, and its gravity is about half that of the Earth. Mars has an atmosphere, and 95% of the air is carbon dioxide. Mars is rich in minerals and energy, and its resources are richer than the moon, so it is also very suitable for human beings to live for a long time. However, because Mars is farther away from the earth than the moon, it will become a place for human beings to explore the universe after the moon.

By comprehensively comparing the conditions of the moon and Mars, it is concluded that the moon will become the first alien colony and the permanent base for exploring the universe, while Mars will become the second alien colony and the second base for exploring the universe.
