[PPS07-18] Re-analysis of images of GANYMEDE

Keywords:GANYMEDE

Ganymede is one of Jupiter’s moons. Numerous images of its surface have been obtained by the Voyager and Galileo spacecraft, which allow us to investigate the global distributions of dark/bright terrains or impact craters exceeding 20km in diameter. However, most of Ganymede is imaged at a resolution of 1km/pixel or higher, and therefore, we can hardly examine the global distribution of smaller features of Ganymede. I re-analyses the Voyager and Galileo images, using multi-flame image restoration.
