Is there water on Mars? Why is Mars suitable for human migration?

Because people now know through science that there is solid water on Mars, which exists on Mars and is the source of life, it can be said that Mars is suitable for human habitation. In addition, through satellite photography, we can see that there is a riverbed on Mars, which proves that liquid water once flowed on Mars. Like the earth, there is an atmosphere on Mars, which is also a necessary factor for human habitation.

If human civilization wants to continue, it must take action to deal with this problem. There are only two solutions. First, start to protect the earth's environment, develop new energy sources and change the traditional energy structure; The other is to fly out of the earth to find it? The second earth? . In fact, human beings have been preparing for these two aspects, while strengthening environmental protection and exploring the planet in space.

Since we explored the universe, there have been two special tasks. The first is to find life outside the universe, and the second is to find a second planet suitable for human survival. However, these decades have passed, and extraterrestrial life has not found a planet suitable for human survival. There is only one goal, and that is Mars. Scientists believe that we humans may immigrate to Mars in the future, because Mars may be suitable for human habitation and is the second planet for human beings. Of course, the premise is that if you want to immigrate to Mars, you must transform yourself. Why do scientists think we humans should immigrate to Mars? Mars is chosen mainly because it is within the livable range of the solar system, and there are some similarities between Mars and the Earth.

In order to know enough about Mars and prepare for our future migration, we humans have launched many probes to Mars in the past few decades, in addition to the satellites in Mars orbit, there are also Mars probes and so on. With the Mars probe, we know more and more about Mars. Some time ago, there was a very exciting news that scientists found liquid water on Mars. It takes a lot of time and energy to find liquid water on Mars. Scientists believe that Mars 2.5 billion years ago, like the earth, had blue sky and white clouds, rivers, lakes and oceans.

Mars is very small in size and mass and closer to the sun. This is the reason for the gravity of Mars. Mars was affected by solar storms, so its atmosphere was blown away by solar storms. As time goes on, its atmosphere becomes thinner and thinner. It is not as thick as our earth's atmosphere. The reason why the atmosphere is thin is because the seawater on the surface of Mars evaporates into the atmosphere and does not return to the ground. As time goes on, the water on the surface of Mars slowly flows away.

But the high temperature will evaporate quickly, which is why our Mars probe can see the trace of liquid water flowing, but it can't find it. Because it is mainly evaporation, it is difficult to form a thick atmosphere on Mars, so it is impossible to say no and it is impossible to preserve liquid water in the thick atmosphere. Without liquid water, we can't move to Mars.
