Ganymede
One of the primary objectives of NASA's Galileo mission was to acquire images of areas that Voyager could not see. This is one such image, showing part of the leading hemisphere of Ganymede. Many fragmented regions of dark terrain split by lanes of bright grooved terrain cover the surface. Several bright young craters can be seen, including a linear chain of craters near the center of the image which may have resulted from the impact of a fragmented comet, similar to comet Shoemaker-Levy/9 which hit Jupiter in 1994.
