A Voyager 2 View of Europa

As Voyager 2 approached Europa, this was the highest resolution global view it obtained before Europa filled more than the entire frame.  Europa was still quite small in the field of view at this point (the time in between this and the global mosaics it would later take was spent studying other targets), and, given the intricate, low contrast nature of its surface, this made this dataset very hard to work with.  It was taken on July 8, 1979, from a range of about 1.2 million kilometers.
