Pioneer - Galileo was useful for what it gave us, but it was absolutely - uh - challenged by its high gain antenna failure. Sometimes we only got a few dozen images (or the equivalent in highly compressed or windowed images) from an entire orbit. Cassini routinely takes thousands of images per orbit, and this new mission will do the same or better. Look at maps of Europa - only a few limited areas are high resolution. Now we will get the whole moon in superb resolution. Plus, don't forget that Galileo was roughly 1980 vintage despite its launch being delayed until 1989. Instruments designed in 2015/6/7 will be orders of magnitude better than early 1980s instruments - especially in terms of composition data.
MahFL - Galileo made a lot more than 2 close flybys of Europa, at least 11 by my count, not including more distant flybys. The first (arrival) orbit (not counted in the 11) produced about as much data on Europa as both Voyagers combined. Phil -------------------- ... because the Solar System ain't gonna map itself.
