How many American girls immigrated to Mars?

Ever since the birth of mankind, we have been looking up at the starry sky and wondering whether there are intelligent and civilized species on a distant planet in deep space.

At the same time, with the development of modern human civilization, human beings are more eager to migrate to other planets, and Mars is the most promising planet.

For space immigrants, people not only have dreams, but also begin to put them into practice. For example, NASA has long planned to land a man on Mars. Once successfully landed on Mars, it means taking the first step to immigrate to Mars, which is of great significance to truly immigrate to Mars in the future.

However, manned landing on Mars is a very huge project, and the whole process is more complicated and dangerous than manned landing on the moon.

A one-way trip from Earth to Mars takes at least 6 months, and every 26 months from Earth to Mars is the best launch period, because the distance between Earth and Mars is the shortest every 26 months, when the Earth, Mars and the sun are in a straight line. People need to land on Mars in the nearest time. At this time, the distance is only about 55 million kilometers, and the farthest distance reaches 400 million kilometers.

Manned landing on Mars must guarantee a return ticket, which basically means that astronauts must stay on Mars for 26 months and wait until the next launch window before returning to Earth. The whole manned landing project on Mars will last for about three years!

Therefore, manned landing on Mars is extremely difficult, and it is necessary to ensure that astronauts have sufficient food sources and security in about three years.

If all goes well, then mankind will consider how to globalize Mars, build settlements on Mars, and realize a self-sufficient Mars colony.

In order to globalize Mars, the first thing to do is to warm it up.

The average temperature on Mars is only MINUS 55 degrees, so it is difficult for human beings to permanently settle on Mars. In theory, it is not difficult to warm up Mars. Humans are very good at warming a planet. In the past 100 years, we have been warming the earth.

Establish a factory on Mars, continuously emit greenhouse gases such as carbon dioxide, and form a sufficient greenhouse effect. Carbon dioxide, which we hate on earth, will become a useful gas on Mars.

With the rising temperature of Mars, it means that people can do outdoor activities for a short time, but they still need to wear oxygen masks because the oxygen content in the atmosphere on Mars is very low. How to increase the oxygen content in the atmosphere of Mars? Algae and moss on the earth are likely to come in handy. They breed rapidly and can release a lot of oxygen.

But in any case, it will take a long time to make Mars the earth, and it may take hundreds or even thousands of years to complete.

Do humans need to wear oxygen masks and radiation protection suits all the time to live on Mars?

Maybe we can accelerate human evolution by manipulating human genes. The process of natural evolution is very long, but through genetic engineering and improving human genes, human beings can complete evolution as soon as possible. For example, modifying human skin genes to make it more resistant to cosmic rays and at the same time resistant to low air pressure. Even humans finally use a large area of skin to get energy and oxygen without breathing through their mouths.

By then, the people who settled on Mars may have been completely different from the traditional human beings, and they will evolve a brand-new human being: Martians. Because of the completely different living environment, Martians may form completely different concepts of language, economy and morality.

Humans will no longer be lonely. When our children and grandchildren look up at the stars on the earth again, they will know that there are human footprints on a planet in the sky.

When humans shout into space again: hello, is anyone there? Waiting will no longer be silence, but: someone, we are here!
