Lunar Highlands Regolith Simulant (LHS-2) - Extended Particle Size for Research & Hardware Testing

What Lunar Highlands Simulant LHS-2 is A research-grade lunar highlands regolith simulant identical in composition to LHS-1, with an extended particle size range up to 2 mm to more accurately represent the full grain size distribution of real lunar regolith. What This Simulant Represents LHS-2 represents lunar highlands regolith using the same formulation, mineralogy, and scientific basis as LHS-1, with the sole distinction being an extended upper particle size limit. While LHS-1 includes particles up to 1 mm, LHS-2 extends the particle size distribution up to 2 mm, reflecting the fact that natural lunar regolith contains a meaningful fraction of coarser grains. This expanded size range provides a more complete analog for surface materials encountered during excavation, mobility, handling, and surface operations on the Moon. LHS-2 is derived from Apollo-era sample analyses, orbital spectroscopy, and decades of peer-reviewed lunar science, with controlled mineralogy, chemistry, density,
