Human beings are species on the earth. The earth means everything to the current human beings. We have also established a brilliant human civilization on the earth. The earth is the mother of mankind!
But humans with wisdom will grow up slowly, just like children, one day they will leave their parents. With the continuous development of human civilization and technology, the earth will not be able to carry the great dreams of mankind.
This means that human beings will inevitably leave the earth. When that day comes, it means that human civilization has officially leap from earth civilization to cosmic civilization.
Which planet is suitable for human habitation besides the earth?
To be honest, there is currently no planet suitable for human habitation, and it is a purgatory planet relative to the earth any week. But everything cannot go too smoothly. Humans can use wisdom to transform the planet's environment and find planets that are relatively similar to the earth's environment as the transformation goal.
and Mars is such a planet.
Mars, the red planet, has four seasons a year, and about 24 hours a day. These two points are very similar to the Earth.
The difference is that the surface temperature of Mars is very low, with an average temperature of only minus 55 degrees Celsius, which is not suitable for long-term living. In addition, the gravity on Mars is very low, only about 38% of the earth's gravity. For humans who have long adapted to the earth's gravity, it will be very uncomfortable to suddenly come to a low-gravity environment.
Staying in a low gravity environment for a long time will cause the human bones to become brittle and the muscles will become weaker and weaker, which is a great test for the human body.
At the same time, low gravity makes it difficult for Mars to attract the atmosphere, so there is almost no atmosphere on Mars, only a small amount of carbon dioxide , and the atmospheric pressure is very low, only one percent of the earth.
Without the protection of the atmosphere and magnetic field, Mars does not have any ability to fight against cosmic radiation, which is equivalent to the direct exposure of humans to high-energy cosmic radiation, which is a very dangerous thing.
If humans want to colonize Mars, they must overcome the above problems one by one, of course, it is not just the above problems. However, wisdom has infinite power, and wisdom can allow humans to overcome various difficulties encountered on Mars.
We can make a bold imagination. After hundreds of years, Mars is no longer a red planet, but slowly becomes a blue planet like the earth. The river flows on the surface and the sky becomes bluer. People no longer need to wear thick protective clothing, they just need to wear an oxygen mask to play happily on Mars.
As more and more people on earth immigrate to Mars, Mars will establish its own social system and even become an independent nation and country.
By then, Mars, which grew up from a "baby", will exist independently of the earth. Martians no longer even thinks that they are Earthlings, but are independent civilizations!
