2.1 Where do you want to build your Moon Camp? We will build a lunar camp in the north of the south pole of the moon, because there is perpetual daylight and sufficient sunlight, which provides great convenience for solar power generation and the necessary conditions for the growth of plants. And the location is biased to the north, facing the earth, which is convenient for communication. The soil there is brittle and easy to excavate. The craters have moisture present, with abundant frozen (solid) water, such as young ice mines, providing water.
2.2 How do you plan to build your Moon Camp? Describe the techniques, materials and your design choices. In the initial stage, we will build a rocket with aluminum alloy and composite materials, and transport astronauts, the most basic living facilities, 3D printers, food, soil and other items through the rocket. The spacecraft can achieve a smooth and accurate landing. After the astronauts land, they will build a mechanical assistant and complete the construction of the camp together with them. First build a gravity device and then excavate the lunar soil, and implement both the ground and the underground at the same time. The lunar soil will be used for the construction of some camps, and another part of the soil will be transformed into other building materials through 3D printing technology.
2.3 The environment on the Moon is very dangerous for the astronauts. Explain how your Moon Camp will protect them. (maximum 150 words) In order to prevent astronauts in space from being attacked by meteorites of different sizes that attack from time to time in the universe, and the very low temperature on the moon, a protective shield will be set up outside the lunar camp. The protective cover is composed of a double-layer water film vacuum with quartz glass outside, which can resist the attack of meteorites, and at the same time, it uses the characteristics of water’s large specific heat capacity to effectively keep warm. In addition, impurities in quartz can interfere with electromagnetic radiation, resist UV light, and reduce the UV transparency of the glass over time, and can also absorb UV light. If there is no attack, the water film will not continuously consume water resources. At the same time, if the astronaut is sick, the medical equipment on the spacecraft will re-test the data. After a clear diagnosis, the doctor will issue a prescription and upload it to space, and instruct the astronaut to dispose of or take medicine. There are also psychological counseling machines.

Water exists in oblique silica meteorites and in the middle and low latitudes of the moon. The water content of lunar soil is 120 ppm, and the water content of lunar rocks is 180 ppm. Water also exists in the permanently shadowed areas of the north and south poles. First, use mechanical claws to dig underground ice cubes, and the lunar rover will concentrate solar radiation and other radiation into the lunar water ice, which will evaporate the water ice material and transport it to the living area pipeline through the transport device in the collector for pretreatment. After treatment,the processed water is collected through the condensation and drying components, and then enters the pipeline in the living area, and is converted into the water dispenser and is distinguish between hot and cold. The set of device not only circulates water, but also reduces water consumption.

Before astronauts set foot in space, they will prepare some vacuum-packed food in the storage room. These foods are easy to eat and can also provide astronauts with a lot of energy, such as compressed food, or can supplement the elements, molecules, Such as protein-rich foods, these foods will be added to the astronauts’ daily meals to provide nutrition and energy. On the moon, due to the high concentration of carbon dioxide, combined with photosynthesis, it provides algae with oxygen and nutrients. Since algae are resistant to severe cold, have thick shells, and have carotenoid-rich cysts, we use algae. We use some algae and plants from the lunar camp planting technology experimental base. These algae plants can be eaten after special treatment, such as algae water spray cleaning technology, outer space microwave technology, etc.

In view of the thin atmosphere of the moon, the solar energy can be fully utilized. First, install the solar panels directly. The solar panels will be installed outside the camp and change direction with the sunlight. Secondly, similar to thermal power generation, use multiple mirrors to focus the sunlight into a transparent tank. Put some relatively stable liquid with a boiling point slightly higher than normal temperature inside, and the liquid boils and rises to drive the turbine to generate electricity. We also consider using microwaves to directly transmit electricity from the earth to the communication antenna. Meanwhile, drills on the lunar rover extract helium-3 from the soil.

Melt some of the entrained calcium oxide and leave the lunar soil in a calcium oxide melt electrolyte, through which oxygen ions flow and produce oxygen at an energized anode. In addition, the lunar soil is rich in calcium oxide. The lunar soil is collected by the collection vehicle, some of which are used for experimental research, and the rest will be transported to the laboratory, where electrolysis is performed to obtain oxygen, and the obtained oxygen will be stored in in the gas tank. In addition to oxygen, a smaller amount of other gas production is also carried out, such as when low carbon dioxide levels in plants are observed, carbon dioxide production is carried out to ensure that daily life and items in the camp are carried out on a normal track.

2.5 Explain what would be the main purpose of your Moon Camp.
To lay the foundation for the construction of a larger lunar base, such as the practice of gravity devices to determine the optimal level of astronauts, and the regulation of oxygen levels. In order for people to explore how to better adapt to the space environment after scientific research in the lunar camp, it not only provides samples for the simulation of the environment on the earth, but also from the perspective of people’s physical adaptation ,provides new ideas, for the exploration of the moon and other planets.
