Abstract
With many current and upcoming space missions exploring C-type asteroids, there is a need for understanding the physical properties of asteroid surface material. Adhesion forces (here including cohesion) are a key component of strength in small asteroids. Asteroid models are highly dependent on values for adhesion, but without in-situ or laboratory measurements on appropriate materials, values are assumed or derived. We conducted a series of experiments with NASA Glenn Research Center's “Adhesion Rig” - a custom instrument with a torsion balance in ultrahigh vacuum - to produce the first measurements of adhesion in asteroid-derived materials (CM2 meteorites). Five individual minerals were also tested to evaluate plausible terrestrial analogs for regolith and to understand the relevance of mineralogical variation observed among C-type asteroids. An average adhesion force of 89 µN was measured for CM2s; similar to previous estimates. None of the minerals tested were similar enough to be considered viable analogs.
