Moon Camp Pioneers Gallery 2019-2020

In Moon Camp Pioneers each team’s mission is to 3D design a complete Moon Camp using Fusion 360. They also have to explain how they will use local resources, protect astronauts from the dangerous of space and describe the living and working facilities.

Project description
Describe your Moon Camp project.

Our base is a large, fully enclosed, mobile fortress based on an early warning system for orbiting the moon. The outer shell of the fortress is completely isolated from the moon’s harsh environment (which is basically the same as the environment on earth) and can be avoided before meteorites strike. The fortress contains control room, living room, cultivate room, scientific research room, energy room, lunar soil collection room and garage and so on. There is a quick-filling airbag below the fortress and a jet engine above. Under normal conditions, the cultivate chamber is opened, so that the plants are fully exposed to light. The lower part of the lunar soil collection chamber can be opened to detect the pneumatic lunar soil collector for resource collection. When an early warning system detects a meteorite attack, our fortress will quickly fill air bags, shrink legs, turn on jet engines, and move quickly.

Where do you want to build your Moon Camp?

We want to set up our Moon Camp at the north and south poles of the Moon. 1. Because there may be a lot of water ice there, it can not only provide drinking water for astronauts, but also make rocket fuel. 2. The lunar polar region is exposed to sunlight for about 70% to 80% of the time. Solar cells can provide sufficient power for the lunar base. 3. The polar region has a small temperature difference and a large number of lunar seas are distributed in the polar regions, which should be an ideal area for scientific research on the moon. 4. It also requires whether the terrain is wide and flat, which is conducive to the takeoff and landing of spacecraft, as well as the ability to maintain smooth communications with the earth and other factors.

How do you plan to build your Moon Camp? Describe the techniques and materials you would use.

We decided to use solar focusing equipment and 3D printing technology to manufacture major building materials. First, the 3d-printed robot and solar energy focusing equipment will be launched. Then, the first phase will be carried out. The main materials of the building will be extracted from the lunar soil, and the fortress shell and internal living facilities will be modular assembled. In the second stage, SiO2 atoms, equivalent tissue plastic, electrified fiber fabric, polyester film and other materials were transported to the base, SiO2 atoms were coated on the shell, a layer of equivalent tissue plastic was added to the shell, and a certain amount of electrified fiber fabric was laid in the fortress, aluminum was extracted from the lunar soil, and thermal insulation layer and pressurized airtight limiting layer were created. In the third stage, people, heat pumps, and jet engines are transported to the base, where the assembly of equipment in the fortress is completed by men in spacesuits.

Water
Food
Electricity
Air

The moon is rich in oxidized iron ore, which is heated and burned to obtain oxygen, and then used to transport spacecraft to collect liquid hydrogen and mix it with water from the moon’s surface and exosphere, which is excited by the sun, or from the colder surface near the poles, which are less radiated by the sun.

1. Establish a food growing room.Grow vegetables, of which kale grows best in the lunar environment and is rich in vitamins.Plant trees, bring microbes from earth, create a small ecosystem and sustain the supply of astronauts.2. Food was cultivated by soilless culture (hydroponics, matrix culture).3. Set up a storage room to store food products, and try to maintain the best temperature of food preservation in the storage room.

1. Use solar energy as power to prepare oxygen and energy for daily life;
2. Use moon rocks to react with methane at high temperatures to produce carbon monoxide and hydrogen. In a second reactor at a lower temperature, carbon monoxide reacts with more hydrogen, reducing it to methane and water, condensing the water, then electrolyzing it to oxygen and hydrogen, storing the oxygen for use while the hydrogen is fed into the system for recycling. Liquid hydrogen and liquid oxygen can be used as ejectors.
3. Nuclear energy: the use of helium 3 in lunar rocks requires the mining of rocks on the lunar surface, the extraction of the element and a series of subsequent steps to convert it into energy.

1. Melt the moon rock into a liquid, then release the oxygen by electric current;
2. Focus the sunlight, heat the ground temperature to 2500℃, extract oxygen from the lunar soil;
3. Use the titanium iron and hydrogen in the lunar sand to generate water, which is then electrolyzed to extract oxygen;
4. There is water ice on the surface of the moon’s poles, which is an important source of carbon dioxide.
5. Recover the breathing products of astronauts and separate carbon dioxide.

How do you plan to build your Moon Camp? Which materials would you use?
The environment on the Moon is very dangerous for the astronauts. Explain how your Moon Camp will protect them.

We use SiO2 atoms as a coating for the fortress’s outer shell, and lay an appropriate amount of electrically charged fabric on the fortress’s inner layer to absorb lunar dust. In the face of galactic cosmic radiation (GCR), the equivalent tissue plastic in the mezzanine of our building will block them. High and low temperatures are blocked by the fortress thermal insulation layer, the thermal insulation layer is made of multiple layers of aluminized polyimide film or polyester film and sandwiched between each layer with non-woven fabric, the film is separated by a network, pasted together to form a thermal insulation layer through thermal reflection to achieve the thermal insulation. In order to deal with the problem of heat accumulation, we use a heat pump of special working medium (R11) to discharge heat. Facing of the threat of vacuum, we use neoprene nylon adhesive cloth and other materials with good air tightness to make the airtight layer. We choose the fabric with high strength and low elongation to make the limiting layer.

Describe a day on the Moon for your Moon Camp astronaut crew.

One morning, I was awakened by my alarm clock. It might be night or day outside. I’ll go to the bathroom first. After washing up, go to the breakfast machine to pick up breakfast, eat breakfast and chat with your teammates. After breakfast, go to the control room. I routinely took notes while looking at the data on the screen. I checked whether the indicators of the polar controller were normal, and checked the temperature, radiation intensity and other data outside the base through the observer. After the inspection is completed, one person is left in the control room to monitor today’s spacecraft and process the data collected yesterday, and use the electromagnetic communication computer to communicate with the earth. The others come to the elevator. Two of them went to the laboratory for scientific research. The remaining one recorded the growth of the plant and supplemented the nutrient solution needed by the plant. Then go to the energy chamber across the way to check the oxygen storage, the electricity supply is stable. Finally, check the progress of the Pneumatic Lunar Soil Collection System, and control the rover to go out on field trips, in the control room to observe the video recorded by the rover’s camera. When necessary, we will go out to explore, but the ordinary scientific research, life is carried out inside the fortress.
