What do science fiction works usually think about Mars colonization?

It is necessary to send people to Mars on a certain scale. Even with the help of the cosmic high-speed passage of the solar system, astronauts need to stay in space for several months. Mars has a thin atmosphere, strong solar radiation and large temperature difference between day and night. Before the first astronauts arrive on Mars, it is necessary to build a fully sealed radiation-proof residence, at least a temporary residence. Therefore, robots are needed to build closed houses and even to smelt metals on Mars, so robots with higher intelligence are needed. Robots are powered by solar energy or nuclear energy, so robots and energy supply systems must be sent to Mars first.
