This base concept has three building phases :
1) On the moon
2) On the way to Mars
3) On mars
Phase 1 : Moon
The base is build on the moon in craters. We use craters to gather rare minerals coming from meteorites & compression + heat from the impact. These valuable minerals are sold on earth to reduce the cost of the base. The base is checked and tested on the moon first.
During this phase, Helium 3 (see: http://fti.neep.wisc.edu/gallery/pdf/wisengr1111.pdf) can be harvested and stored for later usage (Trip to mars or on mars).
Phase 2 : Trip to Mars
The base can be extracted from the moon's dust, the dome is returned and the base can be attached to the central axe of a mothership propelled by a Q-Thruster (see: https://www.youtube.com/watch?v=9M8yht_ofHc ). Rotation will bring artificial gravity during the trip to Mars.
Phase 3 : Mars
Robots have digged mars's soil during the trip. The base can be installed on its arrival. Craters will be chosen to procure more shielding from mars frequent dust winds/storms.
The base is build around a central axe (light well) fixed to a lenticular dome.
The lenticular shape is used for several purposes :
The lower levels are composed of:
- 2 working rings (around the central axe),
- 1 habitat ring (around the central axe),
- 1 ring for machinery & Generators (around central axe to distribute power),
- 1 food reserve & supplies storage (separate),
- 1 water decontamination/filtration & recycling (separate).
The working area will be similar to the ISS, supporting work, experiences & research. 3D printers with a special alloy, fully recyclable, will print all the mechanical parts and tools needed during the missions. This will save a lot of weight for the trip to mars and will grant flexibility by building the best tool for the right job when needed. MPL printers (see: http://www.rapidprototypingmachine.com/mpl/ and https://www.youtube.com/watch?v=xZHTMHXr_6Q ) could also print completely functional objects with even more flexibility. Quadcopter drones will assure small transport (less than 2kg) in the base due to their low energy consumption and ease of maintenance (see: http://www.ted.com/talks/andreas_raptopoulos_no_roads_there_s_a_drone_for_that). On Mars possible strong quadcopter drones/robots (like: http://www.gameofdrones.biz but in kevlar or carbon nanotubes) could scout and work outside the base.
The habitat ring is installed deep underground to shield people from cosmic radiations and benefit from natural geothermal heat. This ring is smaller because we spend less time in this area during the day.
Machinery & Generators
Energy production will be made here. It is protected deep underground as energy is vital to support life. Energy could come from several sources :
If you made it here, you've read the whole concept ! Thank you for reading ! Hope you've enjoyed this flawed concept (but dream is always the beginning of a new reality right ?) ;)
[UPDATE:] Printable separate parts are coming soon.
[UPDATE 06/06/14:] You can print the separate parts of the base & assemble them. The base on mars will be next.
[UDATE 06/08/14:] You can print the complete model. If I have time i'll try to do... the mothership too !
[UDATE 06/11/14:] Fixed holes in mars-ground.stl and mars-ground-optimised.stl. They are now completely manifold.
PS : If i won, the replicator 2 will be given to a fablab i'm starting in my community (http://www.fablab-moebius.org).
The mars soil:
- 2 outside walls
- 10% infill minimum
- You can scale the model down or cut off part of the model to save filament :
- mars-ground.stl (without cut off) = 162g
- mars-ground-optimised.stl (without cut off) = 82g
- mars-ground.stl (with 30mm cutoff (max))= 105g
- mars-ground-optimised.stl (with 30mm cutoff (max)) = 59g
The complete base (separate parts):
- 2 outside walls
- 20 to 30% infill
- 1 x central axe (print flat)
- 2 x half dome (or 1 x dome (but add print support))
- 1 x engine ring
- 1 x habitat-ring
- 1 x working-ring-1
- 1 x working-ring-2
- 2 x food-water-store
- Glue the 2 half-domes, then assemble the complete base like in the schematic.
- You may need to sandpaper the central axe a little to make it go through all the rings.
