Mercury: Fiery Yellow, Scattered Blue

This false color image shows a bright fresh crater exhibiting possible evidence of a pyroclastic deposit on it’s eastern side (shown by the bright yellow); as well as a series of secondaries which have excavated sub-surface material resulting in the blues seen in the north-east corner of the image.
This image was acquired as a high-resolution targeted color observation. Targeted color observations are images of a small area on Mercury’s surface at resolutions higher than the 1-kilometer/pixel 8-color base map. During MESSENGER’s one-year primary mission, hundreds of targeted color observations were obtained. During MESSENGER’s extended mission, high-resolution targeted color observations are more rare, as the 3-color base map covered Mercury’s northern hemisphere with the highest-resolution color images that are possible.
