Interesting post, Robert. Re perchlorates - my understanding is these are formed at the surface. If you dig down deep enough in areas where there are say alluvial deposits dating back millions of years, don't you eventually come to "clean" soil. Wouldn't it make sense to use solar Settling Mars Pros And Cons to enhance ambient light farming on Mars. On Mars - unlike on Earth - simple light structures won't be battered by high winds, blown over, rained on or otherwise be damaged.
So mylar type reflectors could be manufactured on Mars and angled so as to deliver additional solar energy to the greenhouses. What buffer gases would you recommend we use on Mars when creating analogue air. I can see oxygen production being a fairly easy task to accomplish and adding a little CO2 shouldn't be a problem, but what inert gases would we use. Do we have readily available sources of nitrogen and argon? RobertDyck wrote: Did you want answers? First life support. I see multiple life support systems, configured so you can mix-and-match components. That gives options should equipment fail.
On a planet with no breathable atmosphere, a robust life support system with multiple backups is necessary. Periodically the sorbent is "baked out". The CO2 released will be compressed, stored in a pressure cylinder. But that doesn't bake out fully, so it's consumed.
Silver oxide is heavier, but does bake out fully. I have a paper from NASA from the s about silver oxide granuals, regenerated baked out with a microwave oven.
Pros And Cons Of Nasa
Would you believe a microwave oven is more energy efficient? ISS currently uses silver oxide for white EMU spacesuits, regenerated with an electro-resistive oven aka toaster oven. Silver oxide is configured as sheet metal. To use a microwave oven, it must be granuals. Navy nuclear submarines use a tank of liquid amine, bubble air through the tank to remove CO2, and bake out periodically. This has a problem in zero-G, the liquid will float away creating Settlinb breathing hazard. NASA developed an amine paste based on the Navy's amine. That paste is painted on styrofoam beads.
The Pros And Cons Of Nasa
When baking out, ensure you don't heat it so much that you melt the styrofoam. NASA developed Marrs "extended mission life support pallet" for Space Shuttle that fit in the cargo hold. That pallet had styrofoam beads with amine, and extra tanks of oxygen. ISS has large solar arrays, so that provided unlimited power. Amine on styrofoam is lighter than silver oxide, but bulky, large volume.]
