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. |

I might as well join the fray too:
Both of these are from a non-targeted encounter during orbit C9. C9GSSULCUS01 Distance to planet center: 84379 km This four-image mosaic covers portions of Xibalba Sulcus (roughly N-S set of grooves and ridges at the center of the mosaic) and Nineveh Sulcus (the roughly E-W set of grooves and ridges on the right-hand side of mosaic). This mosaic is roughly centered near 28 N, 82 W. Xibalba Sulcus seperates Galileo Regio on the left and Perrine Regio on the right. C9GSGLOBAL01 Distance to planet center: 201468 km This seven-image global mosaic is centered on Ganymede's leading hemisphere, with Galileo Region on the limb at upper left, Perrine Regio near the terminator at upper right. The bright ray crater Cisti can be seen near the bottom. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Here is a montage of Galileo Callisto and Ganymede views I did. I could swear I have a version of the Ganymede image somewhere without the horribly saturated whites, but I am not sure (it was a victim of my crash a few years ago, but I could swear it was backed up). In both cases, the color data is filled in from other orbits and Voyager.
Click the link for full resolution (keep in mind that full resolution is keyed to the Callisto image, which is much smaller). http://www.strykfoto.org/calgan.jpg -------------------- |
