CRISM: Hydrated minerals of Cydonia Colles
In this scene we observe the knobs within the northern lowlands (Acidalia Planitia) that are Fe/Mg phyllosilicate-bearing (pink-blue) and small, patchy exposures of hydrated silica (green) surrounding the knobs. Previously, phyllosilicates have only been found within impact craters in the … Continue reading

HiRISE: Looking at martian salts and clays
This 3D perspective view is a composite of both HiRISE and data from CRISM, another instrument onboard MRO. This view covers a small patch of ancient Martian real estate in Terra Sirenum. CRISM collects spectral data that can be used … Continue reading

Mars minerology points to cold, icy ancient climate
The climate throughout Mars’ early history has long been debated – was the Red Planet warm and wet, or cold and icy? New research published in Icarus provides evidence for the latter. Mars is littered with valley networks, deltas and … Continue reading
