This is a galileo mosaic of Ganymede taken on the G8 orbit. It both reminds me of Cassini mosaics of the Saturnian moons and reminds me of what the Galileo mission might have been like without the antenna problem. It does suffer from compression artifacts and a few data dropouts, and is not mutispectral. Also, there are a few missing spots I filled in with a blank disk. But all in all, it is a nice mosaic. I am surprised it was never released on the planetary photojournal. But then, I am always surprised at the gems that never get released to the public.
Here is a link to a full resolution jpeg version.
