A World View
As of last month, all of the data acquired during MESSENGER's one-year primary mission are available at NASA's Planetary Data System (PDS). The mosaic above is a global view of Mercury assembled from images in the PDS and covers >99.9% of the surface. Download larger versions of this mosaic, at resolutions up to 250 m/pixel, from this global mosaics webpage. Or, explore this mosaic interactively using the QuickMap tool! It's also interesting to remember that prior to the MESSENGER mission, only 45% of Mercury's surface had been seen by spacecraft!
Date acquired: September 7, 2012
