How to use the lunar base

Is there water on the moon? Ouyang Ziyuan said that he hoped very much that there would be water on the moon, or even a lot of water, but it probably didn't work out.

as early as 1999, NASA scientists directed the lunar explorer to hit the Shoemaker crater near the south pole of the moon-also in search of water, but failed to find it.

According to the known data, the content of water and ice in the lunar soil in the permanent shadow area on the moon is very small, even less than 1%, that is to say, one kilogram of lunar soil may only contain a few grams of water. How much water ice there is in the permanent shadow area is still unknown. Even if there are enough water ice, how to take them out and use them is an unimaginable problem in engineering technology-because it is necessary to heat water ice from a deep pit about -24℃ and a few kilometers deep and opaque, and then collect and use it.

"How to make the machine run in such extreme darkness and cold as -24℃ is impossible now." Ouyang Ziyuan said, "Not to mention, the lunar soil should be excavated and piled up. Also, what device is used for heating? How much energy does this process need to consume? How to solve the energy problem? How to solve the transportation problem? " Although the moon is full of helium 3, even on the earth, it will take at least 5 years to skillfully use helium 3 to obtain energy and realize controlled nuclear fusion power generation. Only then can we talk about using helium 3 to obtain energy on the moon. Therefore, there is a lot of talk in the media now, saying that "finding water can build a lunar base, which can solve the drinking water and domestic water for astronauts and lunar base immigrants, and can also produce rocket fuels such as liquid hydrogen and liquid oxygen in large quantities", etc. Academician Ouyang thinks that it is not true. "This is just speculation, which is not consistent with the actual situation."

"In fact, no matter whether water is found on the moon or not, people will go to the moon to establish a base." Academician Ouyang said that as early as the 199s, the United States proposed to return to the moon and establish a lunar base. At that time, it was not known whether there was water on the moon. "If there is water, it can be taken at a low price, which is of course good!" He said, "If there is no water, think of other ways. Without water on the moon, it will not be an obstacle for mankind to establish a lunar base."

He specifically mentioned the lunar exploration orbiter LRO, which is still working. In fact, LCROSS is only an affiliated satellite launched with LRO, and LRO has more missions: around the extremely low orbit only 5 kilometers away from the lunar surface, helping NASA to survey and draw the most detailed topographic map, locking the landing site of manned landing on the moon and establishing the candidate location of the lunar base, looking for the available resources on the moon, detecting the radiation environment on the lunar space and surface, and demonstrating new technologies, and so on. Ouyang Ziyuan said: "These scientific exploration targets are closely focused on manned landing on the moon and establishing a lunar base. This is the highlight!"
