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. |

Thanks a lot to all of you for these great mosaics !
These pictures were taken 10 years ago, and there is still a lot to do with them. Did anybody try to assemble the very high resolution pictures taken during G1 over Xibalba Sulcus ? Due to their "bad" quality, it might be difficult. I even don't know if they really overlap ! I also did not find any mention about the G29 images. What about the regional and color polar cap boundary mosaic near Perrine Regio ? Finally, there were these pictures taken when Ganymede was in Jupiter shadow in order to look for aurora events : http://pdsimg.jpl.nasa.gov/outdir/4846r.img.gif I never heard about them in any publication. As you can see, my "frustration" is still quiet high ten years later, and that's why I really enjoy your posts. Marc. |

Well, I have this color mosaic I put together a few years ago from G29. I will say that because I made it years ago, I used relatively crude methods compared with what I use now, but at any rate, here it is.

You can hardly see the scars on my fingertips any more. -------------------- If Occam had heard my theory, things would be very different now.

I have now completed my earlier post with an improved Ganymede and added Europa and Io.
