If we want to anticipate the scene of Mars colonization 50 years later, reasonable speculation at the moment is just like fortune-telling. Of course, if you just want to imagine the community under the airtight big dome, it's too easy. The forefront of exploration is always in danger, but in the past these dangers have not succeeded in stopping us. This time will not make us stagnant. Quoted from the poet TS Eliot: “Only those who are willing to take risks can find out how far they can go.” Microgravity, long flight, radiation, cosmic rays: Can we overcome these worrisome dangers? ? Even if it is overcome, will there be other problems that are still unknown today? Many experts say: This will be a huge transformation. We must be mentally prepared. BJ Bluth, a sociology faculty member at California State University at Northridge, said: Think about it: When people travel from Europe to the New World, and then to the West and West, people and culture change. Now. "Attitudes, values, and lifestyles have all undergone major changes. The same phenomenon will affect those who have decided to go to other planets to colonize." She also said that this is not just a change of state of mind: Space pioneers are physiological, immune, Changes in culture and society are different from those on earth. Let's assume that we not only land on Mars, but also establish a colony on Mars. We must think about the biological effects of long-term life in the Fourth Planet - and finally having children there. The most important first issue is the effect of radiation. One of the major health concerns of humans on Mars is radiation. Astronauts walking on Mars will be exposed to cosmic radiation in the Milky Way, and in the event of periodic solar storms, the amount of radiation will also increase.
