Why is Mars with harsh environment the most suitable planet for human migration?

There are eight planets in the solar system. There are few signs of life on any planet except the earth. Although Mars and Venus were speculated by scientists that there might be life on these planets 65.438+billion years ago, after all, 65.438+billion years have passed, and the excessive pursuit of human beings cannot bring much change to the future, at most, it is to satisfy the thirst for knowledge. Man is not the only one in the solar system, let alone the universe.

As we know, Mars is a reddish-brown planet with a diameter of 53% and a mass of 14% of the Earth. Compared with the earth, it is slightly smaller in mass and volume, but Mars is one of the few geological planets in the solar system, which is nearly 5500km away from the earth. Based on the above understanding, human beings have been unable to give up Mars, and the surface of Mars is covered with hematite resources. Even if humans don't immigrate to this planet in the future, it is inevitable to transport the resources on Mars back to Earth. After all, it is impossible for human beings to only exploit and utilize the resources on the earth forever. Mars is a planet with extremely bad ecological environment. There is no oxygen on this planet, only thin carbon dioxide gas, which means that Mars has no atmosphere and no magnetic field protection. But mankind still found hope on Mars, that is, in 20 18, the Italian Aviation Administration announced that there was a huge liquid salt lake under the surface of Mars. In 20 15, NASA also said that there was flowing liquid water on Mars, which seemed to declare that Mars had the conditions to breed life, and Mars might not have lost to the earth at all many years ago.

Humans naturally regard Mars as the second hometown of the earth. Elon Musk, CEO of American private space company, said that he would land and colonize Mars in the next decade. However, the ecological disadvantage of Mars is also very obvious. Do humans need to wear thick spacesuits all the time? This is definitely not the way humans want to immigrate to Mars. It is better to listen to the scientists and tell us what is going on!

Scientists say that Mars is really not suitable for human habitation now, but it doesn't mean that Mars can't slowly change to the ecological environment of the earth. Just as the environment in nascent state, where the earth was born, was extremely harsh, about 2 billion years ago, the earth gradually became a green planet. Mars may not be impossible to transform with human intervention!

Because Mars lost its magnetic field 3 billion years ago and became a desolate environment. Scientists can try to change the direction of the asteroid and let it hit Mars. So that the metal core of Mars can work again, but doing so is likely to cause irreparable damage. After all, Mars is very close to the earth, and human beings are not sure whether the fierce collision between the two will have an impact on the earth. Before humans can control the impact of asteroids on the earth, scientists thought of a better way, but it may take a little longer. That is, a large magnetic pole satellite is placed at four Lagrangian points in different directions between the sun and Mars. Their role is naturally to interfere with the continuous attack of solar storm particles on Mars. Let mars slowly have the ability to gather carbon dioxide gas, thus forming the atmosphere. As for how large the magnetic pole satellite should be to achieve this effect, how long it will take. Scientists are still unpredictable. If you still walk, scientists may artificially create a magnetic field on Mars. Just like today's signal base stations, this magnetic field is wide enough to cover a large area.

It is extremely important that the magnetic field equals Mars. With the magnetic field, life on Mars does not have to worry about the attack of nuclear radiation particles. It is because of the magnetic field that the earth has a thick atmosphere and life. As for how such a thin carbon dioxide gas on Mars forms the atmosphere, scientists can naturally intervene in Mars. For example, increasing greenhouse gases. Once the temperature of Mars rises, the glaciers in the north and south poles of Mars will melt. Before long, Mars will become a planet with liquid water resources. Humans don't need to wait for Mars to slowly give birth to the first macromolecule of life under the premise of water. Humans can take the lead in sending some microbes on the earth to Mars. Let them adapt to the living environment on Mars. In this way, Mars will gradually become an ecological planet.
