Is Mars suitable for human habitation?

Mars is not suitable for human survival, because to survive on Mars, we must first solve the problems of gravity and atmosphere.

On Mars, the gravity is only half that of the earth, so people can't live normally on it. We can imagine that at present, human beings have completely adapted to the gravity on the earth, once the gravity of the earth is reduced by half.

Then all the indexes of our body will change, endangering our life and health. Therefore, if we want to immigrate to Mars, we must at least solve the gravity problem first, and transport other meteorites to Mars to increase the mass of Mars, so that the gravity of Mars will gradually increase.

The basic situation of Mars:

Mars is basically a desert planet, its surface is covered with sand dunes and gravel, and there is no stable liquid water body (2065438+September 28th, 2005, NASA announced that there is a small amount of water on Mars. According to Agence France-Presse reported on July 25th, 20 18, researchers from the European Space Agency (ESA) said that the first liquid groundwater lake was discovered on Mars.

The atmosphere dominated by carbon dioxide is thin and cold, and dust is suspended in it, and dust storms often occur every year. The polar caps composed of water ice and dry ice at the poles of Mars will fluctuate with the seasons.

Compared with the earth, the geological activities of Mars are relatively inactive. Most of the surface landforms were formed in ancient times, with dense craters, volcanoes and canyons, including Mount Olympus, the highest peak in the solar system, and Mariner Canyon, the largest canyon. Another unique topographical feature is the obvious difference between the northern and southern hemispheres: the southern part is an ancient highland covered with craters, while the northern part is a younger plain.
