If humans want to land on Mars successfully, how many years will it take?

After turning the exploration target to Mars, human beings showed great interest in Mars. At the end of last century, the space powers represented by the United States kept launching Mars probes to explore Mars, but so far no country has successfully landed on Mars. The main reason is that human space technology has not reached the level of landing on Mars, so developing space technology is the main task at present. Researchers say that "Mo Xie" makes oxygen. As we all know, the surface of Mars is very desolate and the atmosphere is thin. However, Mo Xie can convert carbon dioxide on Mars into oxygen.

This is also one of the most important scientific experiments of NASA on Mars. If Mo Xie succeeds, NASA will put more Mo Xie on Mars in the future, so there will be a lot of oxygen on Mars. In the future, when human astronauts land on Mars, they can get oxygen for life-sustaining activities on Mars through Mo Xie. According to the timetable given by NASA, if Perseverance successfully lands next year, NASA will send astronauts to Mars around 2030. Although humans can't land on Mars in a short time, some scientists still insist that humans can not only land on Mars, but also live on Mars in the near future.

Jim Green, a scientist from NASA, made this sound. He believes that human beings can witness the great feat of landing on Mars in their lifetime, and they will live on Mars, because not long ago, the probe discovered the organic matter on Mars. At present, Mars does not have the environmental conditions for human survival. If human beings want to settle on Mars, they need to artificially create environmental conditions similar to the Earth. After the astronauts successfully landed on Mars and completed a series of sampling and returning to Earth, NASA will start the transformation on Mars, and in the next 100 year, it will start the Mars immigration plan.
