Can humans live on Mars?

It is impossible for human beings to live on Mars at present. Mars is very dry. Although there is water, ice and even running water on Mars, compared with the earth, Mars is simply a desert. Not only dry, but also very cold. In the hottest place on Mars, the temperature can be as high as 70 degrees Fahrenheit at the hottest time.

1. Mars is one of the eight planets in the solar system and the fourth planet in the solar system from the inside out. It is an Earth-like planet with a diameter of about 53% and a mass of 1 1% of the Earth. Due to the axial tilt, the rotation period is similar to that of the earth, and one circle is about twice that of the earth. The orange appearance is the surface hematite (iron oxide). In China's ancient books, Mars was called "the twinkling star", while in ancient western countries (ancient Rome) it was called "the star in the myth of Mars".

2. Mars is basically a desert planet, its surface is covered with sand dunes and gravel, and there is no stable liquid water body (20 15). 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.

3. Compared with the earth, the geological activities of Mars are relatively inactive, and most of the surface landforms were formed in an active period 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.

4. Mars has two natural satellites: Phobos and Phobos, which are irregular in shape and may be captured asteroids. On earth, Mars is visible to the naked eye, with the highest brightness reaching -2.9. Among the eight planets, it is darker than Jupiter and Venus. On September 28th, 20 15, NASA announced the existence of running water on Mars.
