JSC Mars-1MartianRegolithSimulantXRDAnalysis(a) (b)(c)XRD analysis of as-received MARS-1 simulant compared to S06-219 and S06-220processed simulant. MARS-1 as-received powder (a) presents a complicated XRDpattern. Minerals that may be present include albite (NaAlSi 3 O 8 ), magnetite (Fe 3 O 4 ),labradorite (Na 2 O◦2CaO◦3Al 2 O 3 ◦8SiO 2 ), and magnesioferrite (MgFe 2 O 4 ). Some peakscould not be matched with minerals existing in the database. Crystalline phases presentin S06-219 (b) include Fe(bcc), magnesioferrite (Mg Fe 2 O 4 ), and SiO 2 (hexagonalquartz), while those present in S06-220 (c) include Si and SiO 2 (hexagonal quartz). (c) ismostly amorphous.Plasma Processes, Inc 10-11-07
Plasma Processes, Inc 10-11-07Phase 2 Technical Objectives• Collect free O 2 gas from plasma processing gas stream.• Produce & quantify/characterize additional metals (Ti, Al, & Ca) fromplasma processing.• Measure, record, and optimize plasma processing parameters usingreal-time temperature and velocity data along with theoreticalcalculations to evolve O 2 and metals.• Minimize power requirements for the system• Investigate low pressure processing to simulate lunar environment.• Develop initial design for 1/5 scale prototype system suitable fortesting on a robotic mission.• Produce agglutinates and volcanic glass analog particles that whencombined with the current JSC-1A material create a mature lunarregolith simulant suitable for dust, abrasion, tool wear and miningresearch.
