Our goal is to design a self-sufficient base that can be implemented in the next 10 years. Our project is based on real measurements and experiments, as well as on already proven existing techniques.

• In the first phase, food will have to be transported from Earth and the base will not be self-sufficient yet. Above all, the infrastructure on the Moon will be built (strengthening of critical areas, searching for local resources …).
• In the second phase, it will produce its own food and water and will even be able to supply these raw materials to other stations (Gateway) and research will be fully launched.

The base is able to permanently accommodate a four-member crew, which will change after half a year.

Our 3D model contains the first two modules of the base: the self-sufficient habitation and laboratory module (HLM) and the cargo module (CM). HLM is not yet very comfortable for the crew, because it only has to test technologies (plant cultivation, fuel production using ISRU, crew training …), which will be used for the future construction of a greenhouse module (GM) and a large habitation module (LHM), which connects to the base. A pressurized vehicle (PR) is connected to the CM. After the GM is connected and we will be able to produce the fuel on the Moon, it will be possible to supply the Gateway station with food and water.

We plan to build our base at the south pole of the moon, specifically on the edge of Shackleton Crater. This place is advantageous due to the almost permanent lighting and the nearby water deposits. The Artemis program is also heading to the south pole of the Moon, and the Gateway Station orbits to land here, so the site will also be well researched and preparations may be made for the arrival of our base. In the middle of the crater, there is complete darkness and low temperature, which will allow unique undisturbed astronomical observations.

For the construction of our base, we plan to use local resources, which we will process using flexible construction methods, such as 3D printing.
CM arrives first. He will be rendered using Ariane 6. After connecting with transfer element (TE) maneuvers, he will get to the NRHO, where he will connect with the Gateway. He will already have two reusable landing elements (RLEs) waiting to connect CanadArm 3 to the NM on each side. This set then lands on the moon. The LRE prepares for reuse, refuels them, and returns to the Gateway.

In the next phase, the crew will arrive. CM will function as a temporary laboratory in which the suitability of current technologies that will be used in HLM will be verified.

If the tests turn out well, nothing will prevent the HLM from starting on Ariane 6. It will be similar to CM.
Subsequently, the HLM decomposes. The middle folding part (IP) inflates. The rest of the racks are moved from the CM, which can be filled with additional cargo. The ceiling and floor in the EP are also partially folded. Once the HLM decomposes, the 3D printer provides protection against radiation and micrometeorites. This system will ensure that when the astronauts arrive, the base will be largely ready for the arrival of the astronauts.

To protect against micrometeorites, we plan to use mainly ISRU using the 3D printing method. This method would print a Whipple shield. We tried several different methods (regolith + binder from Earth, regolith + sulfur, regolith + sulfur + iron). The best method we experimented with was sulfur lunar crete, but sulfur melts at low temperatures and sublimes. 3D printing on the moon needs more research.
A shield from regolith would also protect against cosmic radiation. There would be 10,000 kg of shield per 1 m². The height would be 1.5 m – 3 m depending on the print density.
The system of radiators / solar panels provides protection especially of the buried parts of the base against extreme monthly temperatures.

We will obtain water from lunar ice, then clean and recycle it, thus minimizing the load brought from Earth.
The water will be mined by carts at the bottom of Shacketlon Crater. We supply them with energy using mirrors located at the edge of the crater. They will be transported here by a commercial lunar lander.
Our robust water recycling system will occupy three racks, allowing for “luxury” such as a shower. It will also allow large experiments with plants to be performed before GM is added.

The food will be transported by Dragon XL from Earth in the first phase. It connects to the Gateway and the cargo is transferred to the CM. In the second phase, we will grow food in GM. The substrate is likely to consist of cleaned regolith and compost and astronaut waste. We are still researching the effect of composting on the atmosphere.

We will use solar panels to produce energy. During the lighting of the solar panels, fuel (hydrogen and oxygen) will be produced from the water by electrolysis. As soon as the panels are shaded, electricity is generated in the hydrogen cells. We are also considering using thermoelectric generators, which would take advantage of extreme temperature differences on the Moon.

In the first phase, we will obtain oxygen by extraction from regolith. Metals are formed as a waste product. We will capture carbon dioxide from the atmosphere and store it in a large tank (the crew will also produce more water than they consume, so we will also have a water tank).
In the second phase, we take carbon dioxide and water into GM, and the plants turn these two substances back into food.

Our base has two main missions: to conduct experiments and prepare the Moon for further settlement. But every project needs financial resources, so we would provide space to carry out commercial experiments, and we can also sell regolith. We hope that in this way we will be able to gain at least some financial self-sufficiency for the base. In the later stages of colonization, we would like to produce at the base from local sources, and launch small satellites.

After waking up at 6:00, the astronaut performs morning hygiene and then moves the sample from the biological rack (BR) to the freezer (FR).

At 6:30 there is a shared breakfast in the lounge. Each astronaut has his own table where he can have personal belongings. They have bread brought from Earth with some vegetables from a small experimental garden (SEG). After breakfast, preparations for extravehicular activity (EVA) will take place, and at 7:00 the astronaut, along with another, is preparing CM and LE for tomorrow’s supply flight to the Gateway. This includes cable connections, engine inspection and refueling preparation. They will also install experimental TEG.

At 12:00, the second part of the crew has lunch, while the other two still perform EVA.

At 13:00, our astronaut returns from EVA and, together with the other, takes lunch and a lunch break extended until 14:30. Because he performed physically demanding EVA, he only trains for half an hour until 15:00. This is followed by an inspection of the station’s systems, which includes checking the station’s wiring, filter condition, tightness of connections and checking for dust. This is very important and our base includes a number of measures to ensure that dust does not get inside and all joints seal well. During the inspection, he finds that one of the filters is already too clogged, so he lifts one floorboard to remove the spare. He’s done at 16:00 and can now do commercial experiments. The first examines the effect of sixth gravity on the mixing of metals in alloys. The astronaut launches and checks it. Then he can do more experiments.

At 17:00 he will start a more demanding analysis of samples in a glove box (GBR). It will take him until 19:00. Then the whole crew will meet for dinner, followed by reading the instructions for tomorrow.

From 19:00 to 21:00, the astronaut has time for evening hygiene and has free time.

He opens the floor and goes to his bed at 9:00 p.m.
