Asteroid spectroscopy: Progress and perspectives
Authors:Michael J Gaffey  Thomas H Burbine  Richard P Binzel
Abstract:Abstract The following discussion is divided into seven major sections. The first section outlines the scientific background and justification for asteroid studies in the context of understanding the formation and early evolution of the solar system. The second section briefly reviews the nature and distribution of the asteroid population. The third section discusses several major unresolved issues in asteroid and meteorite science which can potentially be addressed by asteroid remote sensing investigations. The fourth section outlines the nature and definition of the asteroid taxonomic classes. The fifth section summarizes the existing asteroidal spectral (and other remote sensing) data sets which are used to determine compositions and the techniques employed in the interpretation of such data. The sixth section explores the compositional meaning and diversity of these taxonomic classes and suggests meteoritic analogues for the taxonomic types. The seventh section describes the conclusions—or preliminary results—of several recent asteroid investigations which have focused on particular unsolved issues of the asteroid-meteorite relationship and of the early solar system properties. The final section discusses the overall conclusions and future directions.
