The moon and further space have always had many secrets for us, in order to increase the understanding of outer space, we built a lunar camp in order to further explore the moon, explore for the future to move to the moon, and build a small moon home of our own.
Our camp is set up in two parts: one is outdoor lunar rover, satellite, oxygen generator, water purification device, transfer station, solar panel and other equipment; The second is indoor bedrooms, dining areas, fitness areas, medical rooms and other areas.
Because of the harsh lunar environment and the shortage of resources, we will use recycling technology to make full use of water, oxygen, food, etc. In terms of communication, it has been connected to the earth, reporting the physical condition of people living in the lunar camp in real time, and recording what kind of environment is more suitable for human habitation.
Our lunar camp is mainly to explore what kind of environment is more suitable for human migration.
The Moon’s gravity and many natural environments are very different from Earth’s, so some experimental explorations that require specific environments are more appropriate on the Moon. With the development of human civilization, most of the mineral resources on the earth have been exploited, so the moon, which is rich in mineral resources, is the most suitable development object for human beings at present. Since ancient times, human beings have been full of rich fantasies about the vast starry sky and the boundless universe, and now exploring the moon is only the first step of human exploration of the universe, and setting up rocket and spacecraft transit bases on the moon can help human beings to explore more distant planets.
We choose to be surrounded by abundant resources that can meet the needs of lunar camp utilization; The terrain is relatively flat, which is conducive to the take-off and landing of the spacecraft as the site of the camp.
The Moon is an ideal area for establishing lunar camps at the poles. The lunar polar region is exposed to sunlight about 70%～80% of the time, and solar energy can provide sufficient power for the lunar camp; The temperature difference in the polar zone is small, making the environment of the camp milder; The polar regions are distributed with a large number of lunar seas, and there is a large amount of water ice material to replenish water resources.
Technology: Because the construction of lunar camps consumes a lot of materials, so local materials are an excellent choice, we plan to use lunar rover to mine and collect building materials on the moon, and use 3D printing technology to build camps, and some special materials that cannot be obtained on the moon are considered to carry some from the earth.
Material: silicon-aluminum alloy (light weight, good thermal conductivity, and certain strength, hardness and corrosion resistance); Boron nitride materials (with unique mechanical, thermoelectric, electrical, optical, barrier properties); Aluminum silica glass (with high transparency, suitable for chemical toughening, etc., and the use of multi-layer glass, more effective protection from space radiation).
Design options: Silicon-aluminum alloy for exterior equipment, thickened camp walls, clamshell baffle design for glass sections to cope with more powerful impacts.
Temperature: Real-time detection of the internal temperature of the camp, and control the temperature through certain equipment.
Meteorite: Radar satellites are installed next to the camp to monitor in real time whether there is danger coming, and issue warnings to remind members of the camp to take corresponding measures or evacuate in time.
Radiation: More effective anti-radiation materials for camps and outdoor equipment, and thicker walls to block radiation.
Individual astronauts: formulate reasonable dietary norms to enhance immunity: fitness in the fitness area to increase physical fitness; Set up observation decks, two-ball real-time communication, etc. to solve astronauts’ psychological problems.
In the early stage, the water resources carried from the earth will be used, and the construction of a water circulation system and the mining of lunar water ice will be carried out on the moon at the same time, and the domestic water and urine generated by the camp will be recycled. At the same time, it also replenishes the water source by mining the polar geo-ice material.
Food:The first is some compressed foods and canned food, as well as mealworms that can provide rich animal protein, build a simple ecosphere, grow and cultivate some vegetables with short growth cycles and suitable for survival on the moon, and ensure sufficient food.
Power:Solar power is used to fully collect the light energy generated by the sun during the day and store it, so as to store the electricity needed at night while solving the daytime electricity consumption, so as to maintain the long-term stable operation of the camp.
Air:Oxygen is an indispensable condition for the survival of camp personnel, considering that it cannot be carried from the earth in large quantities, we decided to take local materials, using lunar soil oxygen production technology, the lunar soil electrolysis reaction to obtain oxygen, but also collect oxygen produced by plant photosynthesis.
Solid wastes such as human feces, dead branches and leaves of plants, animal carcasses and food residues are treated by high-temperature aerobic fermentation, and the treated products can be applied as organic fertilizer, and the carbon dioxide produced during the fermentation process can also be passed into the plant cabin as a raw material for plant photosynthesis.
Human urine, as well as the wastewater produced daily, will be purified by water purification systems and recycled or used for plant irrigation.
Our camp has two radars that not only predict the coming of danger, but also keep in touch with the planet. The Earth and the Moon are connected by satellites as bridges.
And our camp has a lot of communication equipment. Keeping in touch with the earth is not only to report the research status of astronauts on the moon at any time, but also to protect the psychology of astronauts.
The research focus of our lunar camp is to further explore the moon, explore for the future migration to the moon, and build a small lunar home of your own.
Low-gravity environment: Because the gravity on the moon is one-sixth of that on Earth, it will pose a great threat to human health in a low-gravity environment, so it is a necessary choice for us humans to adapt to a low-gravity environment.And when there is no gravity, not only the droplets do not drop, but also the suspended matter does not sink, and the surface tension plays a major role in the liquid. The most attractive aspect of the microgravity environment is the effects in liquids and gases, such as the disappearance of heat convection and the elimination of containers for liquids. This reduces interference with diffusion phenomena and atomic transport experiments, allowing theories to be tested more accurately and new experiments to be designed. It also brings new possibilities for the study of overall transport, crystallization, nucleation and supercooling of materials.
No atmosphere:With the mass and volume of the Moon, it should be able to form a certain atmosphere, but this is not the case. Scientists are currently speculating about three possible causes: the moon’s gas is moving faster than the planet’s escape velocity, the moon has no magnetic field, and the moon is often hit by asteroids.The astronauts will study this further.
Physical fitness: To become an astronaut, in addition to more than 1,000 flight hours and good basic physical fitness, you must also pass the “technical test” of the unique facilities of the space city, including: a swivel chair with 24 revolutions per minute to check its tolerance to vibration and vertigo; An electric swing with an amplitude of 15 meters is swung back and forth to test the space motion sickness that may occur to the human body when the spacecraft enters orbit.
The purpose of basic training is, firstly, to enable astronaut candidates to master and complete the scientific knowledge and skills necessary for manned spaceflight, and secondly, to further improve their physical fitness and psychological quality. The physical and mental training that astronauts must undergo, such as being exposed to centrifuges with gravity 10 times the gravity of the Earth, and training in a silence chamber for long periods of time, is unimaginably hard.
The spacecraft of the future is equipped with a laser emitter in the nose, which is the penetrator through which the spacecraft breaks through the atmosphere. And the glass of the cabin is anti-laser glass, which can not only see the direction clearly in the universe, but also make the glass not easy to break. However, in order to prevent the huge heat generated by friction from melting the glass, a lifting protective sheet needs to be installed above the glass.
After reaching the orbit of the moon, there will be a control module and a service module, and the lunar module will dock with them again, waiting for the astronauts to enter the service module, the lunar module will no longer be needed, only the command module and the service module will return to the Earth’s orbit under the control of the astronaut and enter the Earth.
