Spectral variations across Mathilde's surface are small (<5%) and can be attributed to photometric effects. Surfaces tend to appear slightly redder under grazing illumination and viewing. In the NEAR images, regions near the terminator illuminated at large incidence angles appear slightly redder than those illuminated from closer to the normal. On smaller scales, slight color heterogeneities on Mathilde seem to correlate with local slope effects.

note

This contribution is dedicated to the memory of Jurgen Rahe and Eugene Shoemaker, who played key roles in making the exploration of asteroids a reality. Both were involved in the studies that led to the initiation of the NEAR Project. Rahe, in his role as Science Program Director for Solar System Exploration, oversaw the activities of the project until his tragic death shortly before the Mathilde encounter. Shoemaker participated in the Mathilde encounter activities as a guest of the NEAR Imaging Team. We are grateful to D. Yeomans of NEAR's Radio Science Team for close collaboration in the determination of Mathilde's density, to two reviewers for helpful comments, and to B. Chew, who paid close attention to the preparation of the manuscript. We are especially indebted to the Mission Design, Mission Operations, and Flight teams at the Applied Physics Laboratory, and to the Navigation Team at the Jet Propulsion Laboratory. Special thanks are due to G. Heyler, M. Holdridge, A. Santo, W. Owen, J. Miller, D. Scheeres, B. G. Williams, D. Dunham, D. Morrison, A. Harris, C. Porco, C. Shoemaker, F. Vilas, A. Rivkin, R. Binzel, P. Helfenstein, C. Tector, and M. Roth.
