Surface Cleanliness Effects on Lunar Regolith Shear Strength

Publication: Engineering, Construction, and Operations in Space V

Abstract

A study of the influence of surface cleanliness on the geotechnical properties of lunar regolith was undertaken. Surface cleanliness and its effect on soil shear strength were evaluated by applying a recently developed model. Results indicate that a significant portion of lunar soil shear strength is induced by the surface cleanliness. Surface cleanliness considerations for lunar base design are discussed.
