"In this way, we can build houses on a balanced foundation. And this raft foundation really floats on the soil like a raft and will not sink.
At present, the printing efficiency of this lunar 3D printer is relatively low. We have only printed more than 200 square meters so far. According to the first phase planning requirements of our Zhihai Lunar Surface Scientific Exploration Station, we need at least 600 to 80 square meters. About 100 square meters.
Therefore, we will send a large-scale lunar soil 3D printer to this mission. In this way, the printing efficiency will increase linearly. The remaining foundation is expected to take only one quarter to be fully completed.
Only after all these foundations are completed can we start printing the theme building of the scientific research station. According to the efficiency of this large-scale lunar soil 3D printer, the theme building will probably take less than half a year to complete. "
So fast! After hearing Wu Hao's words, both Wu Jianhua and Wu Tong looked surprised.
When Wu Hao saw this, he smiled and waved his hands and said: "This is just the printing of the main body of the building, and there is still a long time before it is actually completed and delivered. Just like the buildings on our earth, after the theme is completed, there are still internal There are a series of follow-up projects such as partitions, painting of interior and exterior walls of the building, installation of windows, pouring of the ground, etc.
The same goes for this lunar scientific research station. After the main building is printed, it is just an empty shell. What we have to do is to perfect this empty shell and make it a lunar scientific research station that can accommodate people to stay and live in. .
To give a very simple example, the empty shell we printed is in a vacuum state. People definitely cannot survive in such an environment, so we need to seal the empty shell, install an airlock, and then It is filled with air and pressurized so that a person can live inside it.
In addition to this, we know that the moon has no atmosphere, so entire research stations are exposed to cosmic radiation. Therefore, for the safety of the people living inside, we need to carry out radiation protection treatment on the entire scientific research station building, such as laying anti-radiation coatings, etc.
Finally, we need to renovate the interior of the entire building and add some life and livelihood support facilities, such as water circulation systems and air circulation systems. The carbon dioxide and other exhaust gases we exhale need to be filtered, and then new oxygen is mixed into the air to make the building more comfortable. The air indicators are always in a normal state. "
Speaking of this, Wu Hao glanced at Wu Jianhua and Wu Tong, and then continued: "In addition to these, we also need to build an ecosystem on the moon, grow some vegetables and food, and breed some animals for our use on the moon. For the consumption of the residents.”
Ah, won't it be transported from the earth? Wu Tong said a little puzzled.
sure. Wu Hao smiled and replied: "But the transportation cost from the earth is relatively high, the cycle is relatively slow, and the supplies are relatively limited. If you want to live on the moon for a long time, you must be able to be self-reliant on the moon, and the most important thing for self-reliance is water. and food.”
Seeing Lin Wei and Zhang Xiaoman walking out of the kitchen, Wu Hao greeted them and then continued with a smile: "Among them, we have solved the water problem.
After our detailed early detection, we found that the lunar soil near Zhihai contains very rich water resources. These water resources can be used through subsequent collection, and the cost of collection is relatively low.
In addition, further south not far from Zhihai, near the south pole of the moon, there is a large amount of solid water, which can also be mined.
Its abundant water resources can fully support the operation and use of our entire Zhihai lunar surface scientific research station, and can even support the operation of a lunar city without any problems.
With water, we can not only use it for human use. In addition, water can also be decomposed into oxygen and hydrogen through solar power generation. Oxygen can be used to maintain the breathing of personnel throughout the research station.
Oxygen and hydrogen are also excellent fuels and can be used for spacecraft launches. In addition, we can also separate considerable amounts of methane from the lunar soil, which is also an ideal rocket booster fuel.
Finally, with water, we can also achieve soilless cultivation. We can use soilless three-dimensional cultivation technology to build a small farm in the research station to provide fresh vegetables, fruits, and even grains to the research station. In addition, we can also use these plant roots, stems and leaves for farming. For example, some scientists have proposed raising mealworms to provide ample protein for astronauts on deep space exploration missions. "
Eh, so disgusting. Hearing Wu Hao's words, Lin Wei couldn't help showing a look of disgust. They had all seen mealworms. When they went to the zoo before, they had never used these things against parrots, so they naturally felt sick when they heard Wu Hao say this.
Wu Hao smiled and said: "Haha, these are all grown in the laboratory. They are naturally very clean and have no problems. It's just that it is difficult for us ordinary people to accept it. Trained astronauts have no burden at all. For them This is a delicacy. In Yunnan, this is not also a delicacy on the local people's tables."
No, I can't accept it anyway. Lin Wei shook her head.
Me too. Wu Tong also followed suit.
Haha, Wu Hao smiled and said: "We naturally took this into consideration, so in order to provide a good food supply and protein supplement for the astronauts and scientists living in the scientific research station, we extended their stay at the scientific research station There are no working hours inside, so through a lot of experiments we have figured out a method of raising edible rabbits in the space environment."
rabbit?
Everyone couldn't help but be surprised.
Yes, Wu Hao smiled and nodded: "It's just a rabbit, but it's a new breed that has been bred so that it can grow in the microgravity environment of space.
Don’t underestimate rabbits. Rabbits have a very strong reproductive capacity. They basically have one litter per month. And because rabbits are relatively small and do not require a large space, they are very suitable for raising in small scientific research stations or even space stations. .
The staple food of rabbits can be the roots, leaves, and unnecessary parts of these cultivated vegetables and fruits. Rabbit feces is also a natural organic fertilizer, thus forming a complete organic ecosystem. "
How to process rabbits on the moon, fry them? Zhang Xiaoman couldn't help but wonder. As a housewife, she was naturally curious about what a rabbit would do on the moon.
Wu Hao heard this and shook his head with a smile: "Although the moon also has gravity, it is still impossible to cook in a microgravity environment. Although it is not possible, it can be steamed, stewed, or baked. There are still many methods."
