How did humans migrate?

I don't know why you are suddenly so interested in Martian immigrants.

1) Will gravity change after moving to Mars?

However, gravity is directly related to the mass of the planet. The mass of Mars is about 1/9 of that of the Earth, and you will become lighter than the Earth.

2) Will the law of life change?

It won't be particularly big, and the length of each day is directly related to the autobiographical cycle of the planet, because the autobiographical cycle of Mars is similar to that of the earth, and the time of each day is still similar, and it is still early and late to work; Of course, the calendar needs to be changed. Now your family uses the Gregorian calendar based on the time when the earth is flat on the sun. When it comes to Mars, it needs to be completely transformed, because one year of Mars is equivalent to two "earth years"; Also, you'd better put on more clothes. The average temperature of Mars is much lower than that of the Earth, which is similar to that of the South Pole. Besides, I'm afraid you'll have to use a pressure suit on Mars. The air pressure is too low and it takes time to get used to it. Adapt to the desert environment and rusty red eyes; Finally, don't expect to use a compass or garlic in your backyard;

Also, are you going to Mars by rocket?

Yes, you can't go to Mars by boat or by car.

4) If so, can some old people, children or people with weak constitution bear it?

Space tools are constantly improving, and the initial selection of astronauts is quite harsh. Later, with the maturity of technology, the requirements were gradually relaxed. I believe that the development of science and technology can offset physical discomfort.

5) How long does it take from Earth to Mars?

Generally speaking, if the through train track is adopted, it will only take a few months, but the energy consumption will be amazing. If a person goes to Mars, it must be like this: first launch into earth orbit, stop at a transfer station (limited by the capacity of the launch vehicle, all components can only be put into orbit once and then assembled), and then pack all kinds of supplies. After that, I think we will choose the Mars launch window that opens every 26 months and transfer the orbit along Herman. Using this time window and orbit can fully save expenses and energy, and the time may take 1.5 ~ 2 years. You can learn more about these professional knowledge.

6) Also, where did you live when you first went to Mars?

Living in the lander should be able to sustain life under pressure.

7) How long does it take to build a house on Mars?

This depends on the determination and investment scale of the international Coalition government to implement this exploration plan, just like if the boss gives you three times the salary, you can finish two days' work every day;

8) What if there is no oxygen?

There is no if, it is. There is almost no oxygen in the atmosphere of Mars, mainly carbon dioxide, but it is still quite thin.
