1. To synthesize a task-specific IL that is efficient at removing Na from sodium-rich phases found on Mars, and has the ability to produce a silica gel as a bi-product.2. To develop, build, test, and use an electrolytic hydrolysis system that will form sodium hydroxide and regenerate the IL.3. To identify the proper mixing ratios of sodium hydroxide, silica, water, and regolith simulant to provide a strong sodium-silicate construction material, while still allowing the material to be extruded and deposited. Next step after this year's work is to test deposition of the material in a Mars-like atmosphere (~7 Torr, 95% CO2).
