Assessment of Additives toImprove Lunar Regolith Simulant• Simulant particles were produced during Phase 1 withmorphology very similar to lunar agglutinates and volcanicglasses• Micron sized Fe observed on particle surfaces and interiors –will determine if nano-size Fe is also present during Phase 2• Restoration of angular/faceted surfaces• Creation of different size agglutinates• Glassy phase / agglutinate separation• Define processing parameters needed to produce either type ofparticle during Phase 2• Combine with JSC-1A Standard to produce mature soil simulant.• Characterization of mature simulant (composition, morphology,hardness, grain interlocking of bulk soil, cohesion, ect.)• Plasma processing is rapid, low cost, and high-volume.Plasma Processes, Inc 10-11-07
