The earth is the home where human beings have lived for millions of years. For this home, before human beings go out of the earth, they all think that they can live on the earth forever. But when we walk out of the earth and see the vast universe, we realize that it’s really not easy for the earth’s beautiful ecology to continue to the present.
Beyond the earth, there are too many disasters that can seriously threaten the earth, such as asteroid impact, solar storm, supernova explosion, black hole and so on. For the earth, the biggest threat is the asteroid impact. The impact of an asteroid 65 million years ago ushered in the fifth mass extinction of the earth, with more than 80% of the species extinct.
This asteroid is only a medium mass object. If it is a larger asteroid, it may directly destroy the earth’s core and make it impossible for the earth to recover. By observing and studying Venus and Mars, scientists found that they may have been as beautiful as the earth a long time ago. It was only after they suffered a major disaster that they became like this. And this kind of disaster probably came from space.
From this, we can see how lucky the earth is to be able to safely avoid the threat from the universe in the four billion years of life, which is a kind of luck. Of course, this kind of luck will not accompany us forever. If human beings want to continue, they can’t rely on luck or be trapped on the earth. We need to go out and spread the seeds of human civilization all over the universe, so that human civilization can last forever.
In order to spread human civilization to all parts of the universe, we need to realize interstellar migration, which needs to fly faster than light. With the current science and technology of human beings, it is impossible for us to achieve this goal, and the areas where we can explore migration are limited to the solar system. Before sub light speed flight, we are not able to carry out alien migration.
Apart from the earth, there is no second natural habitable planet in the solar system, so if we want to immigrate in the solar system, we must first carry out a series of scientific and technological transformation on some relatively good planets to make them meet the conditions for human survival. Mars is the first planet of this kind selected by scientists. Mars is the neighbor of the earth. Besides many similarities with the earth, it is also the planet that scientists think is most likely to become the second habitation of human beings.
In addition to Mars, scientists have also focused on some satellites, such as some of Jupiter and Saturn. They have found that there is a lot of water ice, and water is the source of life. As long as there is a lot of water, it will have an important foundation for future transformation and survival. In addition to these satellites, scientists have focused on some larger asteroids in recent years.
Today’s protagonist Ceres, for example, is a planet actively explored by scientists. Ceres, like Pluto, is a dwarf planet. Its diameter is only 940 km. It is the largest dwarf planet in the asteroid belt between Mars and Jupiter. There are a lot of water carrying minerals on its surface. It is preliminarily estimated that water accounts for 40% of the volume of Ceres, which is a potential habitable planet.
Some people may say, how can a celestial body like Ceres become a potential habitable planet? In fact, when scientists are looking for a planet suitable for human survival, its diameter and size are not the main factors. The main factor is the low-temperature volcanic system. As long as a planet has a low-temperature volcanic system, it means that the planet is an active one, not a dead one.
You know, the earth is a living planet with perfect ecosystem. Low temperature volcano is a kind of volcano formed on the planet with ice shell, which can bring the salt water called low temperature magma from the underground reservoir to the surface, and can promote chemical mixing, thus forming complex molecules needed for life, providing powerful assistance for the formation and survival of life.
The low-temperature volcanic system is an important condition for scientists to find a planet suitable for human survival in the future. As long as the planet with this system exists, it may become a livable planet for human beings in the future. Ceres has such a low-temperature volcanic system, thanks to the discovery of dawn.
Through continuous observation of Ceres, the dawn probe found that there were large white objects on its surface. These white objects were actually the remains of low-temperature magma, which indicated that Ceres was still carrying out more intense geological activities. Now, scientists have determined that Ceres is rich in water resources. Although it looks very desolate on the surface, it is very active inside and has abundant resources.
In the future, such a dwarf planet will not only become one of the habitation planets for human beings, but also become an important resource exploitation place. Of course, Ceres is still relatively small in diameter, and there won’t be many people who can immigrate to it. In the future, Ceres is more likely to become a miner star. People living on this planet are basically miners and their families.
Ceres will not be the main planet for human migration in the future. The real planet for human migration still depends on Mars. Mars is a planet. If it can be transformed into a livable planet, it will accommodate a large number of people. At that time, at least half of the earth’s population will be able to migrate to Mars. In order to successfully transform Mars, abundant water resources are necessary.
Through a large number of observations and discoveries in recent years, scientists have determined that there is water on Mars. At present, a large number of water ice has been found in the north and south poles, but these water ice can not meet the future survival needs. Scientists expect to find a large number of water resources under the surface of Mars, which may also be the key exploration goal of future scientists.
As long as it is confirmed that there are a lot of water resources under the surface of Mars, the success rate of Mars transformation will be greatly increased. Perhaps it will not take many years for Mars to change greatly. It will start from a desolate planet to continue greening, and eventually become a livable planet. A large number of people will migrate to this planet and become Martian humans. We are looking forward to that day.
