Can humans survive on Mars?

Although Mars has some conditions for the origin of life, it does not mean that human beings can survive well on Mars. There are some problems that human beings have to face on Mars.

Radiation protection remains a difficult problem to be solved. In fact, on the way to Mars, astronauts mainly face two kinds of radiation particles that are harmful to health: one is the low-dose but long-lasting galactic cosmic rays. The other is solar high-energy particles produced by solar flares and coronal mass ejections, which usually refer to protons with energy of hundreds of mev, whose energy is much lower than that of galactic cosmic rays and their duration is shorter.

Water is the source of life. The water resources on Mars are very precious. Without water, astronauts will not be able to survive on Mars. Although water is very abundant in the solar system, there used to be large-scale water on Mars, as well as many rivers and lakes. However, there is no available water source on Mars, and the liquid water on Mars just released by NASA is only toxic salt water containing perchlorate, which is distributed on a few steep slopes of Mars impact crater. The water needed by astronauts to survive on Mars is still a difficult point, so the reclaimed water recovery system becomes very important.

So can humans really live independently on Mars? Although there have been rumors for a long time that humans will immigrate to Mars, there are many problems and difficulties in realizing this idea.
