HiPOD 29 May 2023: A Diverse Section of Nirgal Vallis

An image from the CaSSIS instrument on the ExoMars Trace Gas Orbiter (ESA) reveals additional color units exposed in this section of the wall of the valley, which includes some extensive sections of what may be low-calcium pyroxene-bearing rocks. Our HiRISE image can help to resolve textures (breccias) to test multiple hypotheses concerning the formation of the extensive clay-bearing unit in high resolution.
