Three dimensional shape analysis of JSC-1A simulated lunar regolith particles

► 3D shape characterization of JSC-1A, a lunar regolith stimulant (lunar soil). ► Particle size ranges of 20 μm to 300+ μm. ► Comparison with sand and crushed rock particles. ► Database of 3D images, spherical harmonic coefficients, and geometrical properties (e.g. moment of inertia, surface area and integrated mean curvature).
