Lunar Mare Dust Simulant (LMS-1D) - Fine-Dust Research & Environmental Testing

What Lunar Mare Dust Simulant LMS-1D is A fine-dust lunar mare regolith simulant engineered with particle sizes <30 µm (mean ~6 µm) for experiments requiring high-fidelity basaltic lunar dust analogs in environmental, biological, and hardware exposure testing. What This Simulant Represents LMS-1D is a fine-dust variant of the Lunar Mare Regolith Simulant (LMS-1), developed to represent the ultra-fine fraction of basaltic lunar regolith that governs dust behavior on the Moon’s mare surfaces. The simulant consists exclusively of particles finer than 30 µm, with a mean particle size of approximately 6 µm, closely reflecting the fine dust fraction responsible for adhesion, abrasion, electrostatic behavior, and environmental interaction effects observed in lunar mare regions. LMS-1D is mineralogically informed by Apollo sample analyses, orbital spectroscopy, and decades of peer-reviewed lunar science. It is designed to reproduce the physical and chemical behavior of lunar mare dust under
