Mars is located in the livable zone of the solar system. Can humans transform Mars into a livable planet?

Over the past decades, several major countries and institutions in the world have launched more than a dozen Mars probes, of which the United States accounts for the vast majority. American legendary entrepreneur Musk also launched the Mars immigration program, which is currently only a PPT. However, Mars is really hot, and many people who don't know where it is really think that Mars is the target of colonization. Similar to the earth, Mars is also a rocky planet, which means that people can stand on the surface of Mars and enjoy the scenery.

However, there is no charming scenery on Mars. Red dust and iron oxide dust are everywhere. They dyed the whole Mars red, the same color as fire. And like the earth, Mars has a huge iron core, which was originally liquid. It rotates with Mars. Because of the different angular velocities, Mars also had a magnetic field more than 3 billion years ago. Without the protection of the magnetic field, the strong solar wind will directly enter, and the atmosphere on the surface of Mars will be stripped off bit by bit by the solar wind and blown into space.

This is why the atmospheric pressure on Mars is only 1% of that on Earth. Humans need to build a reliable habitat on Mars, or ground facilities that can resist cosmic rays, or dig three pieces to find a place to live under Mars. Secondly, humans need to find enough water and oxygen. Water may not be hard to find because both poles of Mars are covered with a lot of ice. According to the calculation, if the ice melts, it can cover the surface of Mars to a depth of 1 1 m.

However, the preparation of oxygen is a difficult problem. Because it is difficult for machine oxygen production to meet the breathing needs of large-scale people, scientists have come up with a way to find asteroids containing greenhouse gas ammonia in space and let them hit Mars to increase the concentration of greenhouse gases on Mars. If a planet with a diameter of about 2.5 kilometers hits Mars, only about 40 planets are needed to heat Mars to a level suitable for human habitation.

The question of whether Mars is in the habitable zone of the solar system and whether humans can transform Mars into a habitable planet is explained here today.
