Analyze why humans choose Mars as a place for human space immigrants.

20 15 On September 28th, scientists said that there are not only water that has solidified into ice at the poles, but also liquid water that only appears and flows in warm seasons. Scientists point out that their latest findings strongly support the theory that salt water flows on some slopes on the surface of Mars in summer.

There are four seasons.

178 1 year, William Herschel, a famous astronomer in the history of astronomy, inferred that the rotation axis of Mars is also tilted according to the way the marks on Mars move with the rotation of Mars, and the tilt angle is almost the same as the rotation axis of the Earth. In this case, Mars should be like the earth, with winter to spring and cold to summer.

3. There are traces of life

201910/4 Gilbert Levin, a former NASA scientist, said that traces of life were found on Mars more than 40 years ago. Levin said that the research was conducted in 1976 as part of Viking project, which involved searching for traces of life in Martian soil samples.

By studying the geological conditions of Mars, we can understand the changing process of Mars and the similarities and differences between the Earth and Mars. As part of the Mars exploration program, scientists hope to understand the role of wind, water, volcanic activity, tectonic geology and craters in the formation and transformation of the surface of Mars.

Mars has a huge ozone hole, and the ultraviolet rays of the sun illuminate Mars. Perhaps this is why Pirate 1 and Pirate 2 didn't find any organic molecules. Studying the extreme disappearance of the ozone layer on Mars is helpful to understand the extreme disappearance of the ozone layer on Earth.
