Title: Discovery of Possible Mars-Crossing Asteroid Families

Abstract: Clusters of spectrally similar asteroids in Mars-crossing orbits that may be 'families' have been discovered from data obtained by the P.I. in a recently completed reconnaissance program conducted using the KPNO 4m. Follow-up measurements are needed to refute/confirm the significance of this clustering. If confirmed, these 'families' most likely represent outcomes of catastrophic collisions capable of feeding asteroids and meteorite material to the vicinity of Earth. They would be the first known 'families' outside of the main-belt, and one would be the first known family composed of differentiated material.
