Why is Mars suitable for immigrants?

Reasons why Mars is suitable for immigrants: Mars is very similar to the Earth and is rich in natural resources, including water and minerals.

Mars is very similar to the earth. They all have sunrise and sunset, seasonal changes and atmosphere. Although the atmospheric pressure on Mars is much lower than that on Earth, scientists believe that the atmospheric pressure and temperature can be changed by adding greenhouse gases, so that humans can live and work on it. In addition, the level of solar radiation on Mars is low, but human beings can be protected from radiation by some technical means.

Mars is rich in natural resources, including water and minerals. Although it is difficult to find water on the surface of Mars, a large amount of water ice has been found under the ice sheets of Mars' north and south poles. Scientists believe that by heating these ice sheets, ice can be converted into liquid water for human residents on Mars. In addition, there are many valuable minerals on Mars, such as iron, magnesium, aluminum and silicon, which can be used to build and manufacture some necessary facilities.

Mars environment

The orbit of Mars is elliptical. Therefore, where the sun shines, the temperature difference between perihelion and aphelion is close to 160 degrees Celsius. This has a great influence on the climate of Mars.

The average temperature on Mars is about 2 18K (Kelvin, degree-day, that is, from absolute zero -273. 15℃(-55℃, -67℉), but it is 140k(- 133℃) away from winter. Although Mars is much smaller than the earth, its surface area is equivalent to the land area of the earth's surface.

On July 3, 20081,NASA scientists announced that the Phoenix Mars probe had determined the generation of water vapor when heating soil samples on Mars.
