Voyager data revealed details of the surface of Ganymede, known previously to consist largely of water ice, and showed a surface comprised of approximately one-half relatively low-albedo terrain consisting of heavily cratered and furrowed regions, and one-half younger relatively brighter terrain, characterized by distinctive lanes of linear grooves and complex groove polygons. This information permitted the subsequent geological, characterization of Ganymede. On the basis of Voyager data, bright terrain consists of smooth plains and linear grooves (troughs) averaging about 4 km in width arranged in a global network. The bright terrain in which the grooves formed is thought to have been emplaced by cryovolcanic resurfacing of dark terrain, often to a depth of several kilometers. These analyses were the basis for Galileo mission planning and the selection of specific targets to assess and test hypotheses for the origin of the array of features and processes revealed by Voyager. Here we report on data from Uruk Sulcus and several other bright terrain target regions viewed at high resolution on Galileo orbits G1 and G2, and describe evidence for the process of tectonic resurfacing and its significance in the emplacement of the bright terrain as revealed in these data.
