What preparations should people make if they move to Mars?

In 4.6 billion years, only the earth has shown the miracle of life in the long evolution process, but any celestial body, like people, has birth, growth and death.

The earth will eventually age, maybe 3 billion years. At that time, there will be no volcanic activity, no plate movement and no strong earthquakes. The earth will slowly cool down and eventually become a big stone.

Can we find another safe habitat for all mankind, so that human beings can have two habitats?

At present, scientists all over the world realize that transforming Mars is the best choice and object to realize this idea. Mars is one of the planets closest to the earth in the solar system.

Especially when people unveiled the mysterious veil of Venus, they were disappointed to find that Venus is an acidic atmosphere with extremely high temperature and pressure, and it is also poisonous? Death star? . And mars is more like a gentle and amiable kind? Hope star? .

Various evidences show that Mars may be as habitable as Earth? Heaven? . More than 3 billion years ago, Mars still had vitality inside and a thick atmosphere outside. The magnetic field could protect everything on Mars.

Once on the surface of Mars, there is likely to be abundant liquid water, even the Wang Yang Sea. Later, the interior of Mars gradually cooled, the magnetic field gradually disappeared and the atmosphere dispersed.

The liquid water on the surface was not spared, and finally, it became what we see today, cold, dry and dead.

But it doesn't seem impossible to transform Mars and make it have the atmosphere and water again. After all, many new discoveries in recent years are so gratifying.

In 2008, data from a series of Mars probes from NASA and ESA showed that there was a large amount of pure groundwater ice in the shallow surface of Mars.

Even under the Antarctic ice of Mars, there is probably a saltwater lake. Since there is water, what about the atmosphere?

Today, Mars has only a very thin atmosphere, with an average surface pressure of only 6 mbar, which is far from the level of the earth's surface 1 standard atmospheric pressure.

On the earth, we call for emission reduction and cannot release more carbon dioxide, mainly because the greenhouse effect will make the earth's temperature rise continuously, which will lead to many serious consequences.

For example, the Arctic and Antarctic ice sheets melt, the sea level rises, and some low-lying areas may even be submerged. However, on Mars, the more emissions, the better. This will enable it to increase the concentration of the atmosphere, increase the greenhouse effect of the atmosphere and raise the surface temperature of Mars.

Future Martian residents may be able to go outdoors without wearing spacesuits. Ordinary planes can also take off and land on Mars, thus gradually turning red Mars into green. The Earth and Mars will become sisters of the sustainable development of human society.

What a beautiful idea! As early as Carl 50 years ago? Sagan, the founder of space exploration technology company, near Elon? Musk, countless people have thought so and done many feasibility studies.

197 1 year, Carl? Sagan tried to calculate whether the released carbon dioxide can change the atmosphere and ecology of Mars and make liquid water exist stably if the Arctic ice sheet of Mars melts and volatilizes.

Of course, people didn't know much about the reserves of the Antarctic and Antarctic ice sheets on Mars at that time.

However, in August of 20 18, naturally? An opinion article published in Science magazine is not very optimistic about this.

At the current level of human technology, even if all the carbon reserves on Mars are converted into carbon dioxide gas, it may not be enough for Mars to meet the standards of a livable planet.

In other words, with the current level of science and technology, it is impossible for human beings to move freely outdoors if they want to immigrate to Mars.

However, Bian Xiao believes that we don't have to be too depressed, because it is not impossible to immigrate to Mars.

We can still build a closed Mars base, or live directly underground, so that humans and creatures can build an ecological circle in a closed environment and live for a long time.

Of course, there are other benefits. A closed environment is safer and not easy to be hit by meteorites, so please take it easy!
