Mars , a red planet, a barren land, there are no signs of life at present.
Despite this, Mars has always been the first choice for interstellar immigrants in human dreams. With the development of human civilization and technology, this dream is being realized step by step. Over the past few decades, humans have carried out many unmanned exploration projects and have gained more and more knowledge about Mars. The plan to land on Mars by manned Mars has also been put on the agenda.
Dreams are always beautiful, but reality is cruel. Humans still have a long way to go to colonize Mars.
The first thing to do is to heat up Mars. Mars, whose average temperature is only minus 55 degrees Celsius, is obviously not suitable for human survival. So how to heat up Mars?
This is the best thing for humans. In the past hundred years, humans have been heating up the earth. The greenhouse gas that humans constantly emit has caused the earth's surface temperature to continue to increase. We are all deeply touched by this.
However, greenhouse gases that people hate on Earth will become treasures on Mars. A large number of factories can be built on Mars, and while serving humans, they can also unscrupulously emit various greenhouse gases.
But human power is very small in front of nature, let alone warming up the entire Mars. The speed of heating up Mars by emitting greenhouse gases is very slow and it will take hundreds of years to make obvious changes.
Under the protection of the atmosphere, the constantly heating Mars will gradually evolve from a dry and silent planet to a warm and moist, full of vitality.
Mars began to gradually move closer to the earth, the sky became bluer, the river began to flow on the surface, and Mars of Mars began to appear green in stars.
With the atmosphere, people's travel will become more convenient. They do not need to wear thick space suits, or even just need to wear an oxygen mask. The content of oxygen in the Martian atmosphere is not enough to allow humans to breathe freely.
However, no matter how Mars is transformed, it is difficult for humans to transform Mars into a planet exactly the same as Earth. After all, the mass of Mars is very different from that of Earth, and the gravity will be very different. The feeling of life under different gravity will be completely different.
In order to adapt to Mars' life better and faster, humans will select our offspring through genetic engineering and manipulate genes to allow humans born on Mars to adapt to Mars faster.
Then they will become real Martian . The skin will not be as fragile as the Earthlings, and their resistance to ultraviolet rays will be significantly improved, and they will not even rely so much on oxygen like the Earthlings.
In any case, the process of transforming Mars is destined to be full of various unexpected difficulties, especially for previous generations of Mars pioneers, which are even more difficult.
But think about our descendants, in order for our descendants to live better on Mars, no matter how great the difficulties they face, humans will bravely overcome them!
