If you immigrate to Mars in the future, how can humans survive on Mars?

Need heating facilities, water supply and oxygen supply facilities.

First, transport building materials, send remote control robots to complete the construction of some living buildings, then build power facilities to generate electricity, then transport oxygen-making equipment, water-collecting equipment and other equipment to ensure human survival, then transport grain production equipment to produce grain, and then give priority to sending scientists to engage in scientific research.

Water. Without water, human beings can't survive. Most parts of Mars are very dry and there is almost no liquid water. Even if there is pure liquid water, it will evaporate due to low pressure or freeze into ice due to low temperature. Earlier, scientists found strong evidence of seasonal liquid water on Mars. However, through analysis, it is found that these liquid waters are salt water rich in perchlorate, which is inedible for human beings and has limited reserves. In addition, observations show that the solidification of water on Mars forms some ice, which can be used.

If human beings want to survive on Mars now, only by establishing a base on Mars can they survive. Please consider changing the environment of Mars and making it global in the future. By melting polar dry ice, a large amount of carbon dioxide can enter the atmosphere, causing a strong greenhouse effect, thus increasing the surface temperature of Mars.

In this way, polar water ice can be melted into liquid water and released, and then plants can be planted on a large scale, so that the concentration of carbon dioxide in the atmosphere of Mars gradually decreases and the concentration of oxygen gradually increases. When humans are expected to really survive on Mars, this process may take thousands of years.
