HiRISE: Dark and possibly stationary ripples
Dark and possibly stationary ripples in anomalous terrain. These strange ripples are in some anomalous terrain on the Olympus Mons aureole. These dark ripples have not been imaged in about 8 years, so another shot should show movement…if there IS … Continue reading

HiRISE: Dune ripples in Her Desher Vallis
These small ripples, about 10 meters apart, are located in Her Desher Vallis. Her Desher is a small channel that shows evidence of phyllosilicates—silicates with a sheet-like structure, such as clay minerals. Much larger images of this area show that … Continue reading

Large aeolian ripples on Mars
Planetary Geomorphology Image of the Month, July 30, 2016: Ryan C. Ewing (Texas A&M University). Ripples cover the surfaces of sand dunes on Earth and Mars. On Earth, ripples formed in typical aeolian sand (e.g., 0.1 and 0.3 mm) range … Continue reading

HiRISE: Potential active processes in Porter Crater
The extended-mission status of the Mars Reconnaissance Orbiter and the HiRISE camera has greatly increased our understanding of numerous active processes occurring on Mars. By taking carefully planned repeat images of surface, we now have an important record of how … Continue reading
