This observation covers the western edge of a layered mound in Juventae Chasma. The CRISM instrument on MRO has detected high sulfates at the base of this mound, and the resolution power of HiRISE gives us a better look at the area’s morphology.

Why are hydrated sulfates significant? Their existence here might indicate a past presence of water. Scientists may also ask how these minerals were deposited here. In this case, both CRISM and HiRISE can help determine a much clearer picture of the ancient Martian past.

This caption is based on the original science rationale.
