Waters Crater


Ever since MESSENGER entered orbit about Mercury in 2011, the dark impact melt flow of Waters crater has been a feature of interest. Targeted color imaging showed the distinctive blue color of the impact melt flow, inspiring the crater to be named for blues legend Muddy Waters in 2012. In 2013, this high-resolution image was acquired, revealing stunning new details of the impact melt flow beyond those visible previously.

This image was acquired as a targeted set of stereo images. Targeted stereo observations are acquired at resolutions much higher than that of the 200-meter/pixel stereo base map. These targets acquired with the NAC enable the detailed topography of Mercury's surface to be determined for a local area of interest.
