When can humans go to live on Mars? Then the earth will not be like what it is now.

It is still very early. There is no atmosphere, no ozone layer, and no oxygen on Mars. The highest temperature in summer is only 22 degrees, and the average temperature in winter is about minus 125 degrees. At least you have to wait until these conditions are met before you can go up. Anyway, it will take a long, long time, and it will take 1,000 years for the plants on Mars to release enough for humans to breathe.

If technology continues to develop, it is definitely possible, but it will take at least hundreds of years or more. Thousands of years later, because you are talking about living.

The desolate world of Mars

The equatorial radius of Mars is 3332 kilometers, which is only the radius of the Earth. Half of the Earth, its volume is only 1/7 of the Earth, and its mass is 1/9 of the Earth; its surface gravity acceleration is 2/5 of the Earth. On Mars, objects thrown at a speed of 5 kilometers per second can break away from Mars. Due to the small detachment speed of objects on Mars, Mars is difficult to bind many atmospheric molecules, so the Martian atmosphere is very sparse. The main component of the Martian atmosphere is carbon dioxide, accounting for about 95%, and the rest is nitrogen, argon, carbon monoxide, oxygen, ozone and hydrogen; The amount of water vapor is very small, averaging about 0.01% of the total atmosphere. The surface atmospheric pressure is 7.5 hPa, which is equivalent to the atmospheric pressure at an altitude of 30 to 40 kilometers on the Earth.

The solar radiation received on Mars is only that of the Earth 40% of the surface temperature on Mars is 30°C lower than that of the Earth, and the temperature difference between day and night exceeds 100°C. Near the equator of Mars, the temperature only rises to about 20°C at noon, and drops to below -50°C at night. The summer temperature in the polar regions is only -70°C, and can drop to -139°C in winter. After the invention of the telescope, in the 17th century, the Dutch scholar Huygens discovered that there are white polar caps at the north and south poles of Mars, and their sizes vary with the seasons. Change. When it is winter in the Northern Hemisphere, the Arctic cap increases; when it is summer in the Southern Hemisphere, the Antarctic cap decreases. When it is summer in the Northern Hemisphere, the area of ??the Arctic cap also shrinks, just like the ice and snow on Earth melt in summer. Mars There is often a dust storm in the atmosphere that is shaped like a yellow cloud. Local dust storms often appear, and large dust storms can be observed with telescopes on Earth; particularly large dust storms (such as the 1971 dust storm) can cover the entire planet of Mars and last for several months. Dust storms are caused by strong winds carrying dust particles in the lower atmosphere of Mars. It is estimated that each large dust storm covers the southern hemisphere of Mars with as much as 10 to 10 tons of dust.
