Why is Mars suitable for human survival?

Mars is not suitable for human survival, because if we want to survive on Mars, we have to solve the following three problems, namely gravity, atmosphere and oxygen.

Up to now, in addition to living on the earth, many scientists are still exploring whether extraterrestrial planets are suitable for human habitation. Today, although some scientists fantasize about moving to Mars, various conditions do not allow human beings to live on it. Even if some terrestrial planets have been discovered, it may take hundreds of light years or even longer if we want to rely on them.

Introduction to Mars

Mars is the fourth planet in the solar system from the inside out, belonging to the earth-like planet. Its diameter is about half that of the earth, and it takes twice as long to make a revolution tilted from the axis with a similar rotation period. The West calls it Mars Mythology Star, God of War and China call it Fluorescent Star, because it is as bright as fire, and its position and brightness often change.

Its orange-red appearance is because the surface is covered with hematite (iron oxide), and the prefix areo- is Mars in English. Mars was once considered to be the most likely planet in the solar system to have extraterrestrial life.
