Immigrating to Mars-Not Just Imagination

As far as the future space program is concerned, the first is the moon, the second is Mars and the third is the asteroid belt. They are all natural springboard for human beings to go deeper into space, which can hone technology and reserve technology to prepare for better exploration and utilization of space in the future.

It can be imagined that in the future, mankind will definitely go out of the earth and go to a new home, which is almost certain. Where should we go first? Mars or the moon? I think the first choice should be Mars. After all, the environment on the moon is too bad. During the day, the direct sunlight temperature can reach 127 degrees Celsius, and it can be as cold as-170 degrees Celsius at night. Compared with the moon, the atmosphere of Mars is very thin. Although there is no oxygen, there is a lot of water ice under the polar cap of Mars, which is a mixture of water-solidified ice and sand. It is located underground at 65,438 degrees Celsius.

Ice means liquid water. Combined with the strange surface structure of Mars before, it reflects that on ancient Mars, the surface of Mars was also covered with vast oceans and lakes, but for some reasons, Mars lost these.

Some scientists predict that if all the water ice under the Martian stratum melts, it can cover the depth of 1.5 meters on the surface of Mars, which is undoubtedly excellent news for scientists who want to immigrate to Mars. This discovery comes from the study of data sent back by NASA's Mars exploration orbiter MRO.

The first big problem of immigration has been solved, which is to make Mars warm up. As for the method of warming up, many scientists have given various conjectures, but it is very difficult to implement, which is beyond the reach of modern human civilization.

To say that the celebrity who is most keen on Mars immigration is "Mars Madman" Musk. The entrepreneur once said that within 100 years, there will be10000000000 people who will immigrate to Mars. He also said that before doing these things, a human base should be built on the moon, because the moon is an ideal rocket launching site, with low gravity and no atmosphere.

As mentioned above, there are a lot of water and ice reserves on Mars, which can be used as daily drinking water for future Martian residents. It is not technically difficult to obtain these waters. Then there is the problem of Mars' magnetic field and atmosphere.

There is only a weak magnetic field on Mars. In fact, the generator effect of generating magnetic field on Mars has long stopped, and now the remaining magnetic field comes from the legacy of previous magnetization. No magnetic field is a big problem, because magnetic field can protect the planet's atmosphere from being stripped by the solar wind.

How to reconstruct the magnetic field of Mars?

We know that the magnetic field comes from the generator effect of the star core. This effect means that the temperature and pressure in the core of a star are very high. As far as the earth is concerned, the temperature of the inner core is 6000 degrees Celsius, and the pressure is 2 million times that of the atmospheric pressure on the ground. Under this temperature and pressure, the materials in the core tend to move to the colder mantle, and the heavier materials in the mantle tend to gather in the core. It is this convective movement that produces a magnetic field, so

In order to solve the problem of Mars magnetic field, some scientists put forward bold ideas. Some people think that if a big celestial body hits Mars again, it may re-energize the original convection motion and restore the magnetic field.

Others believe that moving a large celestial body into the orbit of Mars and acting as a satellite of Mars can reheat the core of Mars cooling and realize convection.

At present, the above methods are too bold for human beings to do, and some ideas may be realized, that is, placing a powerful electromagnet at the L 1 point of the sun-Mars system. Because this point is a Lagrangian stable point and is located between the sun and Mars, this electromagnet can stay there for a long time, and the applied potential barrier can resist the high-speed charged particle flow from the sun.

The latter method is to create an artificial magnetic field and arrange an artificial magnetic field barrier in the Martian city where human beings gather. This method is also the easiest solution to achieve at present.

With water and magnetic field, what else do you need? That is oxygen and the ozone layer.

People's original idea was to bring the cyanobacteria from the earth after Mars regained its magnetic field and surface water. Cyanobacteria are the hero of the earth's oxygen source. Without the contribution of cyanobacteria, there would be no human civilization today.

Another idea is to build a chemical plant or other factory that emits a lot of greenhouse gases on Mars, so as to raise the atmosphere first. Although straightforward, it makes sense.

As early as the last century, when the United States carried out the Apollo moon landing program, wernher von braun, the designer of Saturn V, conceived the plan of landing on Mars and prepared a feasible plan in advance. However, due to various reasons, including the termination of the Apollo program, the suspension of government funding, and the decline in enthusiasm for space exploration, wernher von braun's great idea was shelved.

Nowadays, human enthusiasm for space exploration has been rekindled. At this time, it is no longer the time for the United States and the Soviet Union to monopolize space. Now, the forces of all parties gather together to see who can win the first prize, and the era of great navigation in space has quietly arrived.
