MARS MARINERIS CITY
City planning - Location
The city we would like to show you in our project is the city of Marineris, which is located close to one of the deepest canyon in the solar system, the Vailes Marineris.
For the first part of the project we made the ground at scale 1 to 1 in the selected area.
The city plan is pretty logical, mainly based on a regular grid of squares 100 meters on the side. Then, on this grid we inserted some big diagonal lines which remind of the expansion plans of Barcelona in the 19 th century by Ildefonso Cerdà.
The idea was to get a building development that could be as much correct as possible from the point of view of collective and private environments.
Given that the limited resources and the inhospitable planet are 2 big weaknesses in the civilization of the planet, we decided to use a grid also to regularly distribute the water resources and the power supplies, the green areas, the public spaces and elevators.
In the Eastern area of the city there's an industrial suburb, in the Western area we arranged a district dedicated to farming and biological research and development. In the center of the city there's a control tower, which represents one of the highest buildings and a reference point for the citizens. At the end of each main arterial street there's a spaceport (six in total), which manages the air traffic to and from Mars.
The surface is divided in regular clusters of about 100x100cm, which are separated from a grid of streets that are reserved for the transport on levitation vehicles.
The streets, as you will see, will be completely covered with solar panels and pedestrians won't be allowed to use them. In fact, pedestrian traffic will be entirely in the underground.
To get to the surface, there will be elevators which lead the citizens wearing a a spacesuit upwards.
In the lower level there will be commercial activities, public spaces and big conveyor belts for faster transfers. All transfers out of the galleries will have to be made with spacesuits.
For the buildings the idea was to use the same materials needed for the space equipment.
In the first phases we expect to reuse the same resources coming from the spacial vehicles and from the expeditions made from the Earth.
To develop a controlled atmosphere around the buildings, we thought about creating some domes where the inhabitants could go around. All domes would be made with the materials available on the Martial soil. The structures would be created with dedicated robots that can 3D print new materials starting from the sand of the Martian soil.
Inside the domes there would be a double cloth of swellable material with the function of containing the oxygen and creating heat insulation to have a comfortable temperature in the inside.
This cloth also shields from the solar radiation which is dangerous for living organisms and filters the solar light to enlighten the environment.
The buildings rising from the ground will be characterized by a regular structure and another structure with more abstract shapes. To every rising building from the ground will correspond a buried part developed deep underground. This will grant a sufficient number of dwelling units for the entire population and the protection from solar radiation.
The dug material will then used in the 3d print process.
We don't know the number of levels needed but we think that the underground development will be one of the best solutions on the planet, also considering that the common spaces will be placed under the ground level and inside the 3d printed dome.
One of the main sources of electricity is given by the nuclear fission reactors which will be created while developing the city.
Another source of power necessary for the activities and the vehicle on the streets will be provided from the solar panels. Such panels, visible on the streets and on the roof of the buildings will grant public lighting, transportation and communications.
We could also use geothermal power stations to exploit the heat from the planet to produce energy. Alternatively, it would be possible to use the methane gas, which has been recently discovered on the planet in interesting quantities.
We didn't consider the water available at the poles as we thought it could be produced from scratch.
The principle is the same used on the ISS. Even during the transfers from the Earth to Mars, astronauts will be part of the program to recycle liquids. To this purpose, the domes in the common areas will retrieve any drop of water deriving from the people, the steam condensed and from the industrial chemical process.
Another process related to the ISS may be useful to produce oxygen. We are indeed thinking on producing oxygen based on electrolysis and thus splitting water molecules in oxygen and hydrogen atoms.
We could then use hydrogen as fuel and as the basis to produce water from the domes' atmospheres.
All vehicles will be equipped with autonomous driving and ionic propulsion engines and as said before, they will levitate on the streets, apart when picking up or dropping off passengers and for loading cargo. Traffic signs will use the same levitation engines.
To keep a city alive, it is necessary to count on the mass production of resources and so exploiting extensive cultivation of cereals, vegetables and fruits. For this purpose we designed some greenhouses for the cultivation and research of new hybrid plants that can adapt to the Mars atmosphere.
Next to this production, we planned the cultivation of edible seaweeds.
We also planned some tanks and bioreactors to produce electricity.
