How to come back after Mars immigrated?

As early as the end of 20 17, the National Aeronautics and Space Administration (NASA) announced that they had solved the energy problem necessary for human beings to survive on Mars, and they planned to transport the first batch of Martian immigrants to Mars in 2024. Then every two years, a group of Martian immigrants will be transported to Mars.

The head of NASA's Mars migration program said that they would give up the previous liquid fuel and use nuclear energy as the propulsion fuel for the spacecraft. The traditional liquid fuel not only occupies a large space, but also has a large weight, which is not conducive to the long-distance travel of spacecraft and is also very slow.

The Mars migration plan will use nuclear energy as the propulsion fuel for the spacecraft. Regarding the public's doubts about the safety of nuclear energy, they said that the nuclear propulsion fuel used by this spacecraft is safe and appropriate, because they use micro-nuclear fission, which, within the controllable range, not only occupies less space, but also has strong propulsion and long service life. The use of nuclear power systems takes up less space, and the saved space allows people to take more power systems to Mars, thus solving the problem of insufficient power.

In life on Mars, NASA also has the corresponding technology to convert space resources into air, water and spacecraft fuel necessary for human life.

The first batch of Martian immigrants will go to Mars with the equipment needed for human survival. They will build a closed ecological cycle system suitable for human survival on Mars, grow their own food and be self-sufficient.

There is also a very important issue about Martian immigrants, that is, the issue of human race reproduction. On earth, the problem of human fertility is a very common thing, but on Mars, it is different. The environment on Mars is not suitable for human survival. People have to face not only gravity, but also all kinds of radiation to survive on Mars, because the atmosphere on Mars is too thin to resist harmful radiation.

Therefore, the first batch of Martian immigrants will need to modify their DNA with the existing medical technology of human beings, so that newborns can adapt to the living environment of Mars and survive under Mars. Only in this way can human beings successfully immigrate to Mars.

There are also many voices questioning this bold plan. Some people suspect that the first Martian will die within two months. Because the past two months of transporting oxygen. Once the crops begin to mature, the amount of oxygen in the closed ecosystem of Mars will drop sharply, which is undoubtedly "suicide" for immigrants.

But NASA doesn't seem to be worried about this problem. Presumably, they also have coping strategies. I think it is very likely that they will bring the vegetation on the earth to Mars and modify the genes of plants to adapt to the environment of Mars, which will effectively solve the problem of hypoxia.

Now the Mars immigration plan is being prepared, and the first batch of Mars immigrants are also training to prepare for 2024. Let's wait and see, this will be an epoch-making event in human history, and it is likely that human beings will immigrate to outer space for the first time. If successful, mankind will usher in the era of immigration from outer space.
