Abstract

Galileo s Solid State Imaging camera recorded six images at wavelengths from 0.41 to 0.99 μm of Europa s trailing hemisphere (∼ 1.6 km/pixel resolution) during the G1 orbit (1st orbit— target Ganymede) of the nominal mission. We have photometrically corrected these data and extracted spectra representing Europa s diverse geologic terrains. The goals of the analysis of these spectra are (1) to determine whether Europa s geologic units differ spectrally from one another,(2) to determine the number of color components necessary to ...
