The moon is closer to Earth, why humans prefer to colonize Mars rather than the moon #space #celestial #science #solarsystem #universe
Mars fan Musk has been working on the Mars immigration program all his life, and he hopes to build a new human home on Mars, so why is Musk giving up the moon so close to us and instead developing Mars hundreds of millions of kilometers away?
When humans stepped on the moon 50 years ago, human beings discovered that this celestial body with the rise of human civilization has a completely different environment from the earth, it is lonely crying and lifeless, and its surface is full of craters that have been hit for hundreds of millions of years.
There is no heavy atmosphere in the sky above it, it is an absolute vacuum, which means that human beings want to establish a new settlement base on the moon, then human beings must solve the problem of atmosphere, and celestial bodies without atmosphere can not only maintain the survival of life but also ensure the safety of the ecosystem, which makes the establishment of a lunar immigration home an almost impossible thing.
In addition to the lunar environment is not suitable for the establishment of a second home, there is also the most important factor, that is, the habitable zone of the solar system, with the development of human science and technology, human beings have found that the earth’s ecosystem can actually maintain a very limited time, we now know that all the energy sources on Earth actually come from nuclear fusion inside the sun.
However, a star’s life is not stable and continuous, our sun has already passed half of its life, and the remaining hydrogen in it can support the sun to continue burning for 5 billion years. But this does not mean that life on Earth, like the sun, can continue to evolve steadily for 5 billion years until the sun goes out.
Scientists speculate that the sun will become larger and hotter in about 1 billion years, and the fusion inside it will become more violent, which means that the habitable zone of the solar system will move towards the periphery, and our Earth’s current position will become an extremely hot zone, just like Venus today.
Because the Earth and the Moon are so close, this means that when the temperature of the Sun becomes higher, the Moon will lose its habitable place in the solar system like the Earth.
So there is no point in modifying the moon, and why can Mars be so valued by humans? What about seeing humanity as hope for the future? In the next issue, we will take you to Mars to uncover the story behind this most important celestial body for the future of mankind.
