Great mosaics! They would have been even more awesome if you included a pixel scale on each of them, just to put things into perspective.

Europa is really an intriguing world, amazing how smooth it looks from a distance, yet has one of the more rugged surfaces close up.

It's actually remarkable how Galileo's old CCD was very capable of producing crisp images, a fact often forgotten thanks to heavy image compression out of neccessity...
Imagine the coverage of these worlds if the HGA was operational! I only wish Cassini was able to capture rapid footprints like this and get long imaging swaths as well.

yes, talking about cassini and galileo, i often ask myself why the resolution of the pics are not so fine at saturn : 30 meters for cassioni, versus 7 for galileo ?

It's not Cassini's resolution that's a problem. AFAIK, Cassini's narrow angle camera has a greater resolution than Galileo had. Galileo did more very close flybys, IIRC there was one that approached to within 80 kilometers to Ganymede (?), and Cassini wasn't doing such extremely close approaches. The closest approach so far was to Enceladus at 175 km and that record is probably gonna hold till the end of the primary mission, it was never really planned in the original tour to be that close.

I was actually talking about pretty long time intervals Cassini's cameras need to readout a picture so the spacecraft moves too far in the meantime to allow the mosaic footprints to overlap so nicely. Another contributing factor is the image packet rate to the solid state recorders, often several instruments need bandwidth and that lowers the speed at which images can be sent to the recorder, but that's a slightly less problematic issue.

Sorry about the scales:
E6ESBRTPLN02: 21m/pxl
E6ESDRKLIN01: 180m/pxl
17ESSTRSLP01: 39m/pxl
I had to smack my forehead about that. As for long swaths, I'll post the huge transect strips from E12 in a couple of days. Galileo actually did return some great stuff in terms of context...occasionally.

Among the Exploitcorporations Europa mosaics are some excellent craters - including those in his Astypalaea Linea post. It's interesting to note a 'new' surface with more craters than a nearby 'old' surface, though presumably courtesy of a Shoemaker-Levy 9 class of impact...

...good area for a lander, perhaps?
