The head of NASA's Mars immigration program said they will abandon the previous liquid fuel and use nuclear energy as the propulsion fuel for the spacecraft, which not only takes up a lot of space but also weighs a lot, which is not conducive to the spacecraft's long and long distance, and is also very slow.
The Mars immigration program will use nuclear energy as the propulsion fuel of the spacecraft, and for the public's questioning of the safety of nuclear energy, they said that the spacecraft uses nuclear energy propulsion fuel is very safe and appropriate, because they use micro nuclear fission, within a controlled range, not only occupies less space and is light in weight, but also has strong propulsive force and long use of the space, using the nuclear power system occupies less space, the use of nuclear power system occupies less space, the space saved can enable the space to be used by the spacecraft for long distances. The space saved would allow people to carry more power systems to Mars in order to solve the problem of people's power shortage.
In terms of life on Mars, NASA also has the technology to convert the resources of space into the air, water and fuel necessary for human life.
The first Mars settlers will travel to Mars with the equipment necessary for human survival, and they will build a closed ecological cycle system suitable for human survival on Mars, where they will grow their own food and be self-sufficient.
There is another very important issue about Mars immigration, and that is the issue of human racial reproduction. On Earth the problem of human reproduction is a perfectly ordinary thing, but on Mars it is different. The environment on Mars is not suitable for human survival, people survive on Mars not only have to face the problem of gravity, but also have to face all kinds of radiation, because the atmosphere of Mars is very thin, not enough to resist the harmful radiation.
So the first batch of Mars immigrants will need to modify their DNA with the medical technology available to human beings, so that the newborns can adapt to the Martian living environment and survive under Mars. Only then will humans be considered to have successfully immigrated to Mars.
There are many skeptical voices about this bold plan. There is a part of the people suspect that the first batch of Mars will die within two months. Because the oxygen transported over to support the 2 months. And once the crops start to mature, the amount of oxygen in the closed ecosystem of human Mars will drop dramatically, which is undoubtedly for the immigrants in the "suicide".
But NASA doesn't seem to be worried about that. I think they have a strategy to deal with this, and I think it's very likely that they will bring Earth's vegetation to Mars and genetically modify the plants to adapt to the Martian environment, which will effectively solve the problem of oxygen deprivation.
Now the Mars immigration program is gearing up, while the first batch of Mars immigrants are being trained for 2024. Let's wait and see, this will be an epoch-making event in human history, and will most likely open the precedent of human migration to outer space. If successful, mankind will usher in the era of outer space immigration.
