What do you think of emigrating to Mars?

At present, there are probes from China and the United States on Mars. Mars exploration or migration has become a part of the space race. Is it really realistic to immigrate to Mars?

China's chief designer said that Mars migration is a fable, and the earth has more development value. I think he considered the difficulty of migration, which could not be realized in a century. In a short time, the earth has more development value than Mars. At present, the exploration of Mars is to reserve technology and knowledge for future interstellar navigation, which is very realistic.

NASA has no clear plan for the date of Mars migration. Perhaps traditional researchers have similar ideas. Although the United States has a technical reserve for manned landing on Mars, it does not mean that it can immigrate to Mars in a short time. It takes a long time for the transformation of Mars base and the adaptation of human beings, and the return on investment is not high, which is also the main reason for the stagnation of the world space industry.

At present, the loudest slogan of Mars immigration is Musk in the United States. Through the continuous iteration of rockets and recyclable technologies, the cost of landing on Mars has been greatly reduced. Personally, it is expected that space x can achieve unmanned landing on Mars within five years. However, there is still a long way to go before the real migration to Mars, and Musk's marketing strategy still has some concepts of stealing. Just like today's machine learning is also called artificial intelligence, it is still far from the imaginary artificial intelligence.

Although Mars migration cannot be realized in a short time, it is the future development direction of mankind. If humans can't even do this, interstellar travel or expansion is a pipe dream. The space resources of the earth are limited. If we don't break through, we will soon be strangled in the cradle.
