Scientific paper
We present initial results from a new analysis of the entire set of Ganymede data from the Galileo Ultraviolet Spectrometer (UVS). We look for trends in albedo and UV absorptions across the surface and interpret the results in light of a new model of plasma-surface interactions. The ultraviolet spectral region (200-320 nm) provides a sensitive probe of the uppermost layers of the surface of Ganymede and thus is an excellent indicator of weathering processes and effects. We are interested in understanding the distribution of oxygen, hydrogen and sulfur ions and electrons to the surface of Ganymede, and in studying the relative importance of the effects of sputtering, radiation brightening, annealing and thermal segregation in creating and maintaining Ganymede's polar caps.
