IDing Meteorite Parent Bodies

Asteroid CompositionsTo determine asteroid compositions,diagnostic parameters must be measured.– Absorption features characteristic of specificmineralsReflectance spectra from ~0.4 µm to 2.5 µm– Minimum spectral coverage needed to obtainuseful mineralogical characterizationsOther Observational techniques provideadditional compositional information– Radar provides constraints on metal content– Thermal infrared (5-20 µm wavelengths) canpotentially characterize iron-free minerals
