How difficult is it to build a lunar base?

This year, the largest lunar simulation experience in history will be held in Cologne, Germany. On the artificial moon with an area of more than 1000 square meter, scientists connected a crane and pulley system to simulate the gravity change of the moon. When you need a rest, you can also enter the rest area and experience the life scene on the earth. The real purpose of this lunar simulation is to expose human's "ambition"-emigrating to the moon!

But the moon is not like the earth. It's too difficult to build a base on the surface of the moon ... the first problem to be solved is water. For the long-term settlement of the lunar base, it is obviously unrealistic to transport fresh water from the earth to the moon. Over the years, rock samples collected at the equator of the moon show that this satellite is dry and waterless. However, with the gradual polarization of detection, the detector found the existence of ice at the two poles of the moon. According to the analysis, each pole may contain 65.438+000 billion tons of ice.

Does this look like an opportunity? Unfortunately, this is not enough. Although ice has been found, it is not clear how thick the ice layer is, whether it is mixed with soil or exists alone. To solve these problems, India's Chandrayaan February probe and Russia's LUNA27 lander will explore the moon in 2022.

The test is still in progress. Now there is a more important job to do, and that is to collect ice cubes. The biggest difficulty in collecting lunar data is energy, because mining machines need energy to work. In the space environment, energy is usually generated by the natural decay of isotope batteries (such as P batteries), but this kind of battery is expensive, which is a bit overqualified for exploiting ice.
