Lunar Highlands Dust Simulant (LHS-1D) - Fine-Dust Research & Environmental Testing

What Lunar Highlands Dust Simulant LHS-1D is A fine-dust lunar highlands regolith simulant engineered with particle sizes <30 µm (mean ~7 µm) for experiments requiring high-fidelity lunar dust analogs, including dust mitigation, hardware exposure, and biological and environmental response studies. What This Simulant Represents LHS-1D is a fine-dust variant of the Lunar Highlands Regolith Simulant (LHS-1), produced to enable experimentation with the ultra-fine fraction of lunar regolith that dominates dust behavior on the lunar surface. The simulant consists exclusively of particles finer than 30 µm, with a mean particle size of approximately 7 µm, closely matching the size range responsible for adhesion, abrasion, electrostatic behavior, and biological interaction effects observed in lunar dust studies. Like LHS-1, LHS-1D is mineralogically derived from lunar highlands compositions informed by Apollo sample analyses, orbital spectroscopy, and peer-reviewed lunar science, and is desi
