Tracing Meteorites to Their Sources Through Asteroid SpectroscopyThe goal of tracing meteorites to their main-belt sources is seemingly impossible given the inherent uncertainties in relating astronomical remote sensing measurements of asteroids to laboratory measurements of meteorites. What's more, the chaotic routes for delivery of meteorites would seem to be sufficient to mask any trace of their points of origin. Yet reasonably compelling links can be made for the origin for two meteorite types: highly reduced enstatite achondrites (aubrites) appear to have a source from the inner most edge of the main-belt known as the Hungaria region; reduced basaltic achondrite howardite-eucrite-diogenite (HED) meteorites are plausibly derived from the large asteroid 4 Vesta. Beyond these specific examples, we seek to find additional evidence to more thoroughly pinpoint original locations for the much wider range of meteorite types and the oxidation environments they sample. A discussion on Near Earth asteroids along with CCD visible and near-infrared spectra observations are presented.
