Mars does not count on the essential conditions to shelter life easily as Earth, but it has the minimum necessary elements that can be modified by man through survival mechanisms to adapt to extreme conditions. Cavendish Station takes its name based on the studies of the British physicist; its concept is based on the use of the conditions of low atmospheric pressure of Mars that give the possibility of bringing the liquid water immediately to its boiling state. The complete process is accomplished through the transitions of water phases that are generated by a system based on the Boiling Water Reactor (BWR). From this physical principle, a cyclic process is developed to generate energy, oxygen and controlled decompression. This latter used in the membrane of the station that keeps active the protection against radiation.

The idealized system of Cavendish Station offers a safe refuge and with the necessary vital conditions for the man, when creating a solid mechanism that uses the hostile nature of Mars transforming it in his favor. The station works thanks to the installation of the “Vital Support Units” (VSU) which are three cylindrical devices, each with a control room, which are located in planned places. Two great moments make this station a reality, Operation and Assembly:

Operation: the station is remain standing thanks to the controlled decompression force which causes the water, which is transported in a liquid state from the tank to the surface, enter in boiling and provoke the particles want to escape to the outside of the tank atmosphere as gas, thus creating a kind of air compressor that keeps the system inflated. In the VSU, two processes are executed. 1) the central turbine of the station that rotates by action of steam to the surface also drives the rotor of the electric generator for power supply. 2) In the second unit is the pressurizing tank that receives the water vapor gas from the previous step, and with an increase in pressure, converts the water to its liquid state again. Finally, the liquid produced returns to the main tank to repeat the process. In the same unit, oxygen is created thanks to NASA’s “Elektron” device.

Assembly: It consists of three modules conditioned for the survival and comfort of its inhabitants. The modules are install inside the station and their objective is to create habitable zones of rest and research. The design (icosahedral domes) represents the chemical structure of water – H2O and its elaboration is carried out in the third phase of the assembly process with simple components: Struts and Hubs, elaborated with basaltic minerals that are obtained directly from the soil of the planet and are the raw material for construction in 3D printing. Due to the rich Iron oxide composition (color characteristic of the soil of Mars), it only requires a light pressure from the printer to emboss Struts and Hubs as strong as iron reinforced blocks, but without needing to use any binder.
