The words of Hu Hao, the chief designer of Chang'e-6, are too exciting!
He said: "When we were sampling the moon, we shoveled up the soil and found that the front and back lunar soil were different, the front side was more delicate and loose, while the back side was slightly viscous, close to the state of agglomeration. Therefore, we have higher expectations for lunar exploration in the future. ”
Did you hear the meaning of Commander-in-Chief Hu Hao's words? He just had to say the sentence that there was water on the back of the moon! The word viscous is not a casual one.
In fact, in the past 10 years, many detectors and observations have shown that water is widespread on the lunar surface. The water content is high at the poles, low at the equator, and there is even water ice in the polar regions, which changes dynamically with the sunshine time.
This is normal, the temperature during the day at the equator of the moon is very high, and some water should also evaporate and escape, so the water content at the equator is low, and the water content at the poles is high.
However, the statement that the polar regions change dynamically with sunlight is a bit informative. Does it mean that during the day when the temperature is high, it is water, and it can flow, and at night when the temperature is low, it is ice? This needs to be further investigated.
As early as when Chinese scientists studied the lunar soil samples of Chang'e-5, it was shown that the solar wind in the mid-latitudes of the lunar surface injected more water into the surface of the lunar soil particles than previously thought, but not much, at that time, the lunar soil collected from the front side of the moon, and one ton of sand contained only 120 grams of water, which could not grow vegetables at all.
Now it's different, if it turns out that there is a lot of water on the back of the moon, then it is really possible to grow vegetables.
Some people say that you can't grow vegetables without air on the moon, and people who think this way know nothing about modern agriculture. Greenhouse can solve this problem.
Shenzhou-14 tried to grow vegetables, and found two major difficulties in growing vegetables in space: in a weightless environment, water is not easy to penetrate into the root system; There is no sunlight in the cabin, and plants that like sunlight do not grow easily.
After research, when it came to Shenzhou 16, the astronaut crew used professional space cultivation equipment to grow fresh ingredients such as lettuce and wheat on the Chinese space station!
What are the conditions for growing vegetables on the space station than on the moon?
There is only a lack of air on the moon, and there is no water, earth, or light on the space station, so as long as you dare to think about it, you can achieve it.
The Chinese are so amazing.
The first batch of crops planted on the moon, in addition to wheat and rice, must be planted, and some people suggest that an osmanthus tree must be planted on the moon, which is the Chinese dream that must be realized. When you can breed animals, you must raise rabbits first. The moon without laurel and jade rabbit lacks Chinese romance.
There are a few more below, which are also a must.
Green onion, this Chinese stir-fry should be a must for everyone.
Chili peppers, at least more than half of the Chinese can not do without.
Potatoes, this dish is a necessity on the table of one-third of Chinese.
Others, like cucumbers, tomatoes, beans, eggplant, can also come with some.
In addition, if there are conditions, you must raise chickens, have eggs to eat, and chicken manure can be used as fertilizer. Chicken and vegetable symbiosis is greener and more environmentally friendly.
