Date Presented: September 29, 2011, at a NASA press briefing Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Of Interest: This high-resolution, targeted image of Sander crater reveals that the bright portions of the floor consist of large numbers of shallow irregular depressions ("hollows"), giving an etched appearance to the surface. This image of Sander has about 10 times better pixel resolution than the one obtained during MESSSENGER's first Mercury flyby.
