This observation had two objectives: 1) image a distinct, fresh-looking gully imaged by MOC; 2) look for change detection in the apron of another sharp-looking gully that was imaged in ESP_015988_1305 .

HiRISE can help view fine-scale morphology, as in this subimage , as well as change detection. With a stereo pair, we can also look for fresh material.

This caption is based on the original science rationale.
