Since the surface of Mars is exposed to high level of cosmic ray and solar wind and radiations, existing natural caverns can appear plausible as proper settlements for human’s future generations.
There are multitude Martian lava tubes on the south-east of Olympus Mons that probably contain a lot of water ice formation in the substratum.
In our project we look for the tubes or caverns of the span sizes that can be domed using the existing technology and yet so extensive than can shelter thousands of Martian residents.
By making use of water ice deposits, and solar and wind energy on the surface of Mars, we seek to develop huge forests inside the caverns functioning as green lunges to supply sufficient amount of oxygen and food for residents.
The idea we come up with would include this process:
– To locate suitable Martian lava tubes using satellites, robots and drones.
– To install solar cells and wind turbines to generate energy. Turbines will not need big expensive standings as they can be buoyant in air by use of balloons filled up with hydrogen derived from water. During dust storms that can last for months these wind turbines are suitable alternatives to solar energy resources.
– To employ manufacturing robots to produce fiberglass using the silicone on the surface of Mars.
– To employ weaver-filler robots that are able to consolidate fiberglass tubes filled up with the Martian surface sand into dome structure covering residential Martian caverns. These robots can also produce fiberglass sheets for internal structures.
– The upper surfaces of dome structures are made by transparent fiberglass tubes filled up with water (made from ice deposits). Inside the tubes, algae are nourished with CO2, phosphorus and nitrogen to be prepared to produce oxygen. They also serve as food resources as well as bio-fertilizers and soil stabilizers.
Our plan for the underground Marsotopia embraces a green dome containing algae on the top, research centers that need close access to the Martian surface in the upper spaces, residential complexes in the middle, agricultural zones in the lower parts, and water supply units and sanitation on the bottom. There will be fiberglass cylinders installed on the wall of caverns to transmit water to upper levels. Insider water cylinders algae can also be grown using artificial light. All residential, public spaces and agricultural zones remain covered until their level of oxygen escalate to the degree than can be uncovered so that the entire cavern is charged with O2. However, some specific places remain always enclosed and insulated to serve in case of severe unpredicted conditions.
