Cohesion of regolith: Measurements of meteorite powders

The cohesion of particles has a significant effect on the properties small bodies. In this study, we measured in open air, cohesive forces tens micron-sized irregularly shaped meteorite, silica sand, glass powder, and spherical particles, using centrifugal method. addition, estimated amount water vapor adsorbed under measurement conditions. meteorite are times smaller than those an ideally particle correspond to submicron-scale effective (or equivalent) curvature radius surface. Moreover, based expect airless bodies be approximately 10 larger air. Based results, estimate that asteroids typically sub-micro-Newton range, fast-rotating microns size.
