Title: Characterization of spacecraft target asteroid 2002 GT

Abstract: The Deep Impact spacecraft is currently on course for a January 4, 2020 flyby of the sub-km near-Earth asteroid 163249 (2002 GT). This fly- by will provide high-resolution images to address a host of scientific questions related to the physical, chemical and geologic properties of small asteroids. However, little is currently known about 2002 GT. As part of a larger campaign to characterize this object during its favorable 2013A apparition, the last such opportunity before the 2020 fly-by, we propose to (1) perform visible and near-IR spectroscopy of this asteroid to constrain its composition and (2) to obtain thermal infrared photometry to constrain its albedo and thermo-physical surface properties. These data will aid in planning and development of the flyby sequence and to ultimately contribute to the interpretation of the fly-by images. This program has broader implications for understanding a general class of objects (~100m to multi-km scale near-Earth asteroids) that are ideal candidates for future spacecraft and human exploration.
