Regolith migration and sorting on asteroid Itokawa.

High-resolution images of the surface of asteroid Itokawa from the Hayabusa mission reveal it to be covered with unconsolidated millimeter-sized and larger gravels. Locations and morphologic characteristics of this gravel indicate that Itokawa has experienced considerable vibrations, which have triggered global-scale granular processes in its dry, vacuum, microgravity environment. These process...

Understanding the Nature of Metal Segregation in Asteroid Regolith

Metal/Silicate Fractionation: The process of re-golith formation on an asteroid normally results in the sorting of the asteroid's regolith, a process that would involve segregation of the denser, less brittle metallic from silicate particles. It has been proposed that, as a result of mobilization of volatiles, the position of this particle layer in the regolith would depend on initial size and ...
