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. |

Bjorn, honored to be the first to complement you on this remarkable work!
Interesting that Ganymede seems to have its own 'look' on this scale. The crater rims seem to be quite rounded, almost eroded in appearance...I'm at a loss to explain this, unless they are truly ancient and this is the result of micrometeoroid action over the ages as we see on the Moon. However, this conflicts with the existence of very prominent fracture/faulting features...odd indeed. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
