Why is Mars livable that modern scientists can't study?

Hello, dear. First of all, there is no suitable temperature on Mars, and the temperature on the surface of Mars is very cold. According to the spirit rover launched by the United States, it is at 200. The data sent back the following year showed that the highest temperature on Mars during the day was only about five degrees Celsius, and the lowest was minus 15 degrees Celsius. Through the comprehensive analysis of more detection equipment, it is concluded that the average temperature on the surface of Mars is about MINUS 55 degrees Celsius, the highest temperature is 27 degrees Celsius, and the lowest temperature is MINUS 133 degrees Celsius. It can be seen that the climate on Mars is mostly cold, and even during the fishing season, the temperature is the earth. Spring or autumn is more suitable, too big for anyone to live. Humans need to wear spacesuits to get on.

Second, Mars doesn't have the right amount of oxygen. According to scientists' research, the atmosphere of Mars is much thinner and more toxic than that of the Earth, and the air pressure is only 0.500 semicolon 0.8% of the atmospheric pressure of the Earth. The main component of the atmosphere is carbon dioxide, accounting for about 95%. But it accounts for about 3%, and the oxygen is even less, only 0. 15%. Therefore, if humans don't have the oxygen supply state carried by spacesuits, we can only survive for two to five minutes in such bad air conditions on Mars, and then we will die.

Third, the gravity of Mars is relatively small, because the diameter of Mars is about 53% of that of the Earth, and its mass is 100% of that of the Earth. Moreover, the gravity of Mars is far less than that of the Earth, and people's bones and muscles may suffer long-term damage, similar to the loss of living in the space station for a long time.

Fourth, there are frequent sandstorms on Mars, and there is no stable liquid water. Mars is basically a desert planet, with gravel on the surface dunes and no stable liquid water. The atmosphere dominated by carbon dioxide is thin and cold. Suspended, in which sandstorms often occur every year, so conditions like Mars are not suitable for human survival. Therefore, if human beings want to immigrate to Mars in the future, they must transform it, such as making Mars more like the earth and suitable for human life on Mars.
