main
- NOT-YET-PLAYABLE pre alpha, just tech experiments so far
- http://ghoulsblade.schattenkind.net/webspacesim/
- realistic simulation of landing and constructions on the moon using remote controlled rovers/robots and chemically processing on-site material
details
- a little hobby project worked on irregularly
- tech: playable in browser without plugins, using webgl and javascript
- aims for realism, using current technology and prices as far as possible.
- current data (prices,weight,chemical composition,...) is just preliminary for getting the simulation mechanics running and will need intensive fact-checking and research later
- optional experiments with theoretical launch & propulsion systems only as long as they are scientifically realistic in the near future
- In-situ resource utilization by chemically processing Lunar Regolith to extract chemicals and process them to manufacture Solar Cells, Propellants, Structures and other things
- construct more/bigger machines by combining components imported from earth with cruder parts made from in-situ chemicals (using Additive Manufacturing / 3D Printing)
- experiments with plant-growing e.g. Hydroponics (light, temperature, and nutrients from chemicals)
- later experiments with other planets, moons, asteroids, satellites,probes,landers and in space construction, and transporting material between multiple sites.
- Maneuvers using Orbital Mechanics like Gravitational Slingshot and Atmospheric Drag to conserve fuel
- 2012-09-29 separated into own project, was originally space-test inside mountainfort experiment
outline
- one "free" launch to moon (incurs dept)
- make solar cells + fuel + electro-magnetic launch systems on moon
- launch fuel to earth orbit : pay back initial dept and then trade for equipment and material to expand further
- access and harvest materials from near-earth-asteroids
- possible goal to make self-sustaining (not reliant on earth-launches) colony for x thousand humans on moon or in orbit
rationale
- no time pressure, remote-controlled robotic rover doesn't need food or air, solar cells last several years, so even inefficient manufacturing machines will fullfil their tasks eventually
- due to vacuum (no air friction) and much lower gravity than earth, an electromagnetic launch systems should be feasible (if in doubt add rocket-assisted)
- welding in vacuum was already successfully demonstrated on the ISS, and a robotic rover with 2+ arms should be able to fixate metal components and move a welder
- smaller rough components can be produced using 3d-printing technology
- aluminium powder as well as hydrogen from the water-ice discovered in recent years can be produced as fuel with oxygen (plentyful since major moon minerals are oxides)
- silicon and aluminium from regolith can be used as basis to create solar cells, at least in combination with further materials/components imported from earth
- since by now it is already possible to print solar cells using a standard inkjet printer on a paper surface, it should be possible to manufacture them on the moon using aluminium, silicon, and further componets imported from earth
- unlike on earth, where roof-area is very limited and costly, high energy_per_area is not required.
- according to wikipedia a falcon 9 heavy can launch above 50 tonnes into earth orbit for 80-125 mio $
- advances in thin-foil solar cells allow for high energy-per-kilogram efficiencies, so a large amount of solarcells could be brought initially to jumpstart local production.
- vaccum allows using thin aluminium foil without oxidation. this allows large scale mirror-arrays to increase solar cell efficiency
- aluminum and iron for structures can be produced from regolith
- due to high launch cost from earth, bringing fuel and iron/aluminium for structures from moon should be interesting economically, and at least allow trade for components that can only be manufactured on earth
- human inhabitation requires at least heating, oxygen, water, food and waste reprocessing
- for food production hydrophinically grown plants are interesting, besides oxygen and water, those require mainly carbon and nitrogen? which have to be imported from earth or asteroids.
- partial reusage from waste-reprocessing should be possible
