Is there water on Mars? Is there oxygen? Can humans go up and live?

When the astronauts successfully entered space, scientists realized that the earth was only a tiny existence in the grand universe, and many resources on the earth were quickly consumed by us. We should consider finding the second planet in the universe suitable for human habitation, and Mars is one of the goals. If there is water and oxygen on Mars, then people can live there. This problem has troubled many people. In fact, according to the analysis, it should be possible.

First of all? Water is the source of life? If you want to survive, you must have water resources. At present, there are many places on Mars that are very similar to the Earth, such as the time of the four seasons, atmospheric pressure and the composition of the air. These are very good conditions. The only thing missing is that water resources have not been discovered, so we can never become the second planet. Now, if there is water and oxygen on Mars, according to the analysis, human beings can indeed move there to live, but other conditions are omitted.

How did you survive in the first place? There are some other places, such as the weather, which are different from the earth and can't adapt to it in the past. There is also the problem of radiation, which may cause genetic mutation. This will be a huge problem that cannot be overcome.

So even if there is water and oxygen on Mars, human beings can't survive for the time being. At the very least, we should exclude some people from living for a period of time and see what happens. Otherwise, it is likely that once an accident happens, everyone's life will be a big problem, and it is also a big problem to come to Mars by spaceship. After all, carrying many people at a time, fuel and route conditions are big problems. The universe is not the earth, the radiation inside is terrible, and everything exists.
