In case of a catastrophe on the earth, which planets can humans go to in space?

? Now that China has developed science and technology, we have gone to Mars and the moon, and there is no place suitable for human habitation.

We are faced with all kinds of risks, some of which are caused by ourselves, such as global warming, nuclear proliferation, bioengineering, germ warfare and so on. More importantly, nature has brought a series of extinction cycles to the earth, such as dinosaurs. Maybe we only have a few days to rule the planet. Great thinkers believe that in order to avoid a completely destroyed natural disaster, human beings must be scattered on multiple planets.

At present, Mars and the moon are the places that human beings can choose. Compared with the moon, Mars is more livable, but also more challenging. Private companies can mine trillions of dollars worth of gold, platinum, rare earth metals and helium -3 on the surface of the moon. The lunar outpost will enable scientists to conduct radio and optical astronomy research far away from the noise and light pollution of the earth. The gravity of the moon is only one sixth of that of the earth. Establishing a space port on the moon can provide a cheaper starting point for our mission to Mars and other planets in the solar system.

The reason for colonizing Mars is more romantic. Mars provides us with some protection in the event of environmental disasters such as large-scale asteroid impact, nuclear war or climate change. Brave adventurers have also made various preparations for this. Space Exploration Technologies, Google and Tesla have made some promising progress in space exploration and artificial intelligence. Colonizing the moon seems easy, and it only takes a few days to get there. This distance allows the robot to communicate in real time and control remotely.

At present, people have explored the moon and Mars successively. Although there is no place suitable for human habitation, Mars is more suitable for human habitation than the moon, so people are more interested in the exploration of Mars. It is hoped that mankind will realize the wish of another immigrant just around the corner.
