Today's image features Neruda crater, named for the Chilean poet Pablo Neruda. The crater exhibits several central peaks punctuated by a more recent, small crater, resulting in a rugged profile of ups and downs if one were to traverse the crater floor. Similarly, the crater's namesake Neruda experienced a number of ups and downs in his life, from success as a poet, through poverty, war and ultimately alleged poisoning.

The set of images shown here in color was acquired as part of a sequence intended to monitor any changes in the calibration of the multispectral Wide Angle Camera over time, but it also gives a beautiful view of Mercury's cratered southern hemisphere. The craters Magritte, Neruda, and Sher-Gil can be spotted within this scene. North is to the top-left of the image.

The upper part of this view of Mercury's surface includes a swath of material that has reflectance that does not strongly increase toward longer wavelengths, a property described as relatively "blue" in color. The bluish material also has lower overall reflectance than Mercury's average surface. The terrain to the south and west has a more reddish color. A major puzzle of Mercury's geology is the identity of the particular rock types that correspond to these colors. Visible in the scene are the craters Amaral, Neruda and Sher-Gil.
