I've been processing some of the high resolution Galileo Ganymede images recently. As far as I know the two mosaics below have not appeared at the official websites (at least not in this form) so in a sense they are 'new'.
The first one was obtained during the G1 flyby in 1996. It covers a part of Memphis Facula which is centered at roughly 15°N, 132°W. The images were obtained at a distance of approximately 5000 km from Ganymede's center. The second one was obtained during the G28 flyby in May 2000. It is centered near 14.5°S, 319.7°W. The images making up the mosaic were obtained at a distance of roughly 4500 km from Ganymede's center. I will probably post more Ganymede mosaics later this month or next month. |

Apparently we're seeing similar temp controlled sublimation at Iapetus and Hyperion. There's very un-intuitive feedbacks going on in the processes, I suspect, and quick-and-dirty arm-waving analysis can only go so far. These terrains will look *STRANGE* when we finally get some hard lander down on these objects. The fractured and faulted ice terrains of Europa and volcanic terrains of Io (not the S02/Sulfer etched terrains and the like) will look positively familiar, I suspect.
