Crescent Jupiter
Crescent Jupiter Galileo captured this view of an incredibly thin crescent Jupiter on September 10, 1997. Quite a lot of atmospheric features are visible even from this high a phase angle. NASA / JPL / Ted Stryk

Despite its antenna problems, Galileo accomplished some remarkable science. However, a major loss was the lack of global views during the orbital mission. Ignoring the resurrected OPNAV image I posted recently, this is largely true. However, in between Galileo's 9th and 10th orbit, it obtained some highly compressed, high phase global imagery. The images are reduced to 75% of the original resolution because of the damage from interlacing and compression.
