Due to the increasing demand for mineral resources by humans, we have built a -Kale Crest-lunar base on the moon to transport rare resources from the moon to the Earth through a space elevator for commercial, scientific, and other purposes. In building materials, we use peripheral materials (geopolymers on the lunar surface) to meet construction needs; In terms of style, we adopt a submerged cloud shaped terrace design, which is beautiful and practical; During the construction process, we use 3D printing to add different substances to the mixture to achieve different needs; In the living and leisure areas, we have many recreational facilities to ensure a high-quality life for astronauts.
“Cabbage Summit” aims to meet the growing demand for minerals and energy for commercial purposes. We excavate minerals and energy on the moon and transport them to the synchronous orbit and space station through space elevators. Some of the minerals are used to exchange for necessary materials for lunar life, and the rest will be transferred to the company’s account in the form of virtual currency. “Cabbage Summit” is committed to mining high-quality minerals to alleviate the mineral crisis of mankind. We transport buyers in the second week of every even numbered Earth month. If there is a need, please dial xxxxxxx.
The base of Kale Crest is located in a pit in the equatorial Jinghai region. The equatorial region has the thickest lunar soil cover and abundant helium 3 content, which conforms to the original intention of the base construction; The angular velocity of the equatorial region is equal to the angular velocity of the lunar synchronous orbit, and its high rotational speed provides the possibility for the construction of space elevators. Due to the terrain of the pit, the temperature in the pit in the Jinghai area is maintained at 17-19 degrees Celsius throughout the year, which can ensure that the base is free from most cosmic radiation and dust interference, greatly reducing the pressure on survival. Due to the low gravity of the moon, people only need to rely on hydraulic lifting devices to get up and down.
The main body of Kale Crest adopts 3D printing technology, and the foundation material mainly uses geosynthetics (lunar concrete) from the lunar surface, which can protect against cosmic radiation and micrometeorites. Fiber and glass fiber reinforcement similar to potato chip structure are embedded in the middle to enhance the pressure bearing performance of the floor. During the preparation process of geopolymers, 98% of the water can be reused. In addition to the alkali activator that needs to be transported from the earth, more than 90% of the remaining water can be obtained from the moon, ensuring a high utilization rate of in-situ resources.
For the wall part, we use barium silicate glass with excellent radiation protection performance, and attach a mixture of lunar surface weathering and periclase as an outer insulation layer to resist the extreme diurnal temperature difference of the moon.
The space elevator is a method similar to elevator transportation that transports mined minerals to the lunar synchronous orbit. However, the distance from the lunar surface to the synchronous orbit is very remote, which requires the material to have a huge compressive capacity. Therefore, we chose carbon nanotubes as the main material for the rope. It has the strongest taper ratio among known materials and can withstand the tremendous pressure of gravity. In order to prevent meteorite attacks, we abandoned the traditional cylindrical rope and chose a ribbon rope instead.Compared to traditional ropes that break on impact, ribbon ropes can withstand multiple meteorite impacts.
The top of the kale is built in a pit, where the subsidence of the terrain stabilizes the temperature throughout the year and maintains a range suitable for human survival. At the same time, our walls are made of silicate glass, which can greatly reduce the harm of lunar cosmic radiation to astronauts and effectively avoid the wear and tear of lunar dust on the outer surface of the base by utilizing its radiation resistant properties and matching the topography of the pit. The gym on the top floor of the base and the small hammock in the greenhouse allow astronauts to relax and relieve stress during their leisure time. Our astronauts received medical training before arriving on the moon, and the drugs and medical devices in small medical rooms can treat common diseases.

Water is the material basis of people’s survival. On the Kale Crest, the main sources of water are lunar soil and water ice, which can be heated and melted to obtain a large amount of water.After collecting and settling in the ground, it is transported to the catchment tank for physical decontamination and storage, and provided to astronauts to ensure the normal operation of their work and life.At the same time, we will also recycle urine, domestic waste water, industrial waste water and other ways to store through chemical impurity removal, as a backup water source.

On the Kale Crest, there are a wide range of food sources. Early astronauts were fed and clothed with food brought from Earth. After the construction of the camp is on track, the cells of cattle and rabbits are cultured on gelatin scaffolds to produce human meat. Vegetables and fruits (spinach, cabbage, bell peppers, carrots, tomatoes, strawberries, etc.) in the greenhouse will be supplemented to provide the astronauts with the required protein and nutrients. After the completion of the space elevator, it will also regularly deliver some food that is not usually available on the moon to the base, diversifying the diet and providing additional meals for astronauts.

As our Kale Crest is built in a natural pit, electricity is a necessary condition for maintaining the normal operation of the base. Here, about 80% of the electricity reserves come from nuclear reactors, which release a large amount of energy during helium 3 fusion. Helium-3 is injected into ilmenite in both vacancy and gap modes, and heated to above 1000K. At this time, the amount of helium-3 released is the most ideal. In addition, the space elevator is equipped with rotatable solar panels that store light energy as a backup energy source in higher-performance flywheel batteries.(97words)
(1) In the interlayer on the top of the greenhouse, a layer of microorganisms (Chilobacterium ammoniacum, Chlorella, etc.) is paved to transport the oxygen generated by them downward to various areas through pipes in the wall. In addition, the plants in the greenhouse can provide food and evolve air while also providing a portion of oxygen for the base.
(2) Oxygen is obtained by striking the gold foil with carbon dioxide. Impacting CO2 onto the inert surface of the gold foil, the gold foil cannot be oxidized and should not generate molecular oxygen. Therefore, oxygen can be continuously released from the surface of the gold foil, and a large amount of oxygen can also be obtained by this method.(119words)
Disposing of garbage on the moon is a complex task that takes into account multiple aspects such as limited space, environmental protection and resource utilization. First, we sort and compress the garbage to reduce the space for storage and transportation. For combustible refuse, waste incineration can be used to burn it into ash and smoke, and filter out harmful substances. Non-combustible waste can be disposed of in landfills. Recycling is also an important link, through the classification of recycling and recycling, to minimize the pollution of garbage to the environment. Second, on the moon, we use microbes to process human waste and turn it into useful gases and fertilizers. The use of specific microorganisms, such as anaerobic bacteria, can decompose organic matter in low-oxygen environments and produce methane gas, providing potential value for fuel and energy production.
Earth-moon: At Kale Crest, we have a detector equipped with a high-gain directional antenna, and a solar panel provides 20 watts of power to it, concentrating the limited power in one area to ensure the transmission of information between the earth and the moon. There are also special signal receiving stations on the Earth, which receive and transmit signals through huge directional antennas. In addition, we use our own coded signal transmission, so that the information is not easy to steal.
Between lunar bases: In view of the vacuum environment of the moon, electromagnetic wave is adopted for signal transmission between lunar bases, which is not comfortable with the medium. When it is necessary to communicate, the astronaut turns on the intercom, talks into it, and the device converts “sound – electromagnetic wave – sound” to restore the sound signal. They also use radio waves to transmit words, data, images, etc.
At Kale Crest, our scientists study geology and biology.
In terms of geology, although it has been a long time since man first landed on the moon in 1969, there has been relatively little exploration of lunar craters during this period. Although our camp is mainly commercial oriented, we still have a strong scientific research capability. Now our experiments are no longer limited to bringing soil samples from the moon back to Earth for monitoring. After mining ores and lunar soil by manipulator in the operation area, they will be transported to the main body of the base by transport vehicles, which is convenient for scientists to conduct research. The research is mainly in the following aspects: (1) The unique zirconium mineral in Jinghai area – Jinghai stone is studied by means of independently developed ultra-high resolution testing means.(2) To study when magmatic activity once stopped on the moon; (3) to study the underground network structure of the craters in the static sea area to further understand the inner structure of the moon.
In terms of biology, we will take advantage of the special conditions on the moon to mutate oxygen-producing microorganisms brought from the earth, in order to find a microorganism with higher oxygen production efficiency and better supply to the astronauts’ work and life. At the same time, although we adhere to the principle of green environmental protection and try to use recyclable materials, it is inevitable to produce a lot of difficult to dispose of garbage, so the research on the efficient decomposition of garbage microorganisms will be added to the research.
In order to train the best astronauts for the “Kale Crest” lunar program, our training program is divided into three main categories: knowledge and skills, physical fitness, and mental fitness.
Knowledge and skills: In order to ensure a sound lunar landing and research, our astronauts will receive intensive training in medicine, physics, astronomy, mechanical engineering and other disciplines. In addition, we will arrange for astronauts to be equipped with relevant technical skills in spaceflight expertise, flight procedures and mission simulation.
Physical fitness: In order to better adapt to the weightless environment in space, especially out-of-cabin activities, simulated weightlessness training is the top priority in our training. We will take underwater weightlessness training, where astronauts wear underwater training suits for underwater simulated weightlessness practice, which guarantees that astronauts will conduct simulated weightlessness training in a neutral buoyancy tank, develop astronauts’ operating habits under weightlessness conditions, and complete simulated training for egress activities, which is also applied to spacecraft or base egress operation ergonomics assessment and egress procedure reasonableness verification. At the same time, we will also allow astronauts to conduct a large number of survival and life-saving training and large joint exercises to ensure readiness for all missions.
Psychological quality: Psychological training is an essential part of astronaut training. Because the space mission needs to leave our familiar environment, and this environmental change on the psychological impact is great. Astronauts need to first adapt to the situation in space from the psychological point of view. Increase psychological stability. To ensure the reliability of our commercial research, we train the entire crew together to improve their efficiency and teamwork in space.
When astronauts need to travel to new destinations, they will use lunar vehicles for exploration. These vehicles will be designed to withstand the rough terrain and extreme temperatures of the lunar surface so that astronauts can easily traverse the surface of the Moon.
When the astronauts need to return to Earth, they will use the Lunar Module to return to Earth orbit and then use the Space Elevator to return to Earth. These vehicles will be designed to be highly autonomous and reusable to support future lunar exploration missions.
