The space immigration program began in the 20th century.209Please respect copyright.PENANAyLGQjlBkl0
Personally, I think the idea is likely to come from science fiction that existed in the 19th century. I love watching science fiction and movies. 209Please respect copyright.PENANAUuz5QHwr2C
Recalling the old novels and old movies that I have read, it is even more difficult to find that the bridges that have appeared in them will also come true in the future, until today.209Please respect copyright.PENANAw0WhMqHQLW
In the 20th century, some scientists began to advocate space immigration programs. The reason is nothing more than fear that the earth will be destroyed due to various disasters, and human civilization will come to an end completely. In order to ensure that human civilization will not be terminated, the immigration plan also seems to be imminent and has to be done.
Humans once thought about colonizing the moon, the closest satellite to Earth, and then thought about other inner planets, such as Mars, Mercury, and Venus. I have also thought about the moons of the outer planets such as Europa, Callisto, Ganymede, Titan, Enceladus, etc......
Later, human beings also discovered several Earth-like objects one after another, one of which is that I will set foot on Kepler 452b, commonly known as Earth 2, in the future.
In order to develop space immigration programs, humans have also done many, many different experiments; the most famous of which is "Biosphere 2" (Biosphere 2).
In 1982, a group of extremely radical environmentalists who called themselves the "Synergist" began to propose, led by John Allen. Later, after attracting the participation of many scientists, the plan gradually formed a closed space living base built by the proposed "Biosphere 1 (Earth)" that everyone will know in the future.
In 2142, the first permanent space base appeared on the lunar surface.
In 2198, a second permanent space base appeared on the surface of Mars.
In 2246, a third permanent space base appeared on the surface of Ganymede.
Although bases have been successfully built on the above three planets, the problem of large-scale immigration has still not been solved.
The breakthrough point was in 2337, almost 600 years ago, when human beings finally discovered the interstellar gate connecting the Cygnus --- "AGHARTA" in the North Pole.
