The design of our moon base proposal is founded on the following concepts: we want to colonize the moon to use it as a starting point for future missions, to extract raw materials and to create a totally self-contained ecosystem for about 50,000 people, free from any chemical and electromagnetic pollution. This experiment should therefore also serve to develop the technologies to be repeated on earth, whose thin layer of atmosphere is going to be destroyed by human activities.
But we don’t want to live on the moon staying under a mountain of regolith! We expect to be able to realize in every single moment that we are on the moon, and not only trough a porthole: we want to be free to observe the lunar landscape and see the sunlight just as we do it on earth.
So the large pressurized dome that constitutes the lunar base will be made of cushions consist of several layers of high strength ETFE, supported by a network of ropes in traction (about 30 cm section wires placed at a distance of about 1m to resist to an internal pressure of about 0.8bar). The cushions will be fully transparent and will also provide thermal insulation, required to mitigate effects of temperature changes typical of the lunar surface.
The protective dome, beneath which we will create an artificial atmosphere that allows us to breathe, will be completely transparent so that we could go outside our houses and observe the lunar landscape and the sky.
That’s why we need to protect our moon base from both radiation and micrometeorites. This will be possible by installing below the soil a large artificial magnet, made of a solenoid realized by a spiral of electrical cable placed beneath the ground of the moon base that, through the passage of the current, will generate a magnetic field similar to the one that protect us from cosmic rays on the earth.
Moreover, an “artificial cloud” will protect the weak transparent layer by micrometeorites: this shield will be supported by curvilinear elements generating a large dome placed about 1500 mt above the lunar city. These structural elements, composed by high pressure inflated Vectran tubular (therefore also resistant to the impact with the micrometeorites), will support a series of stiffened metal sheet panels, reflective at their intrados.
This artificial “cloud” will be sufficiently distant from the moon base ground, so it will not obstruct outside views; its inner side will be mirrored, in order to diffuse the sliding sunlight and increase natural lightening of the moon base. By varying the tilt of the mirrors, it will be possible to adjust the inside reflected sunlight in order to manage it as a function of the day-night rhythm that will be recreate inside the moon base.
The technologies required for realizing the lunar base are already available on the earth!
The low gravity and the absence of any meteoric events allows to realize these enormous and high rise structures with very thin structural sections.
