CRISM: Olivine and pyroxene in ejecta from northern plains crater
CRISM scene HRL00003BEE covers an area in close proximity to a crater in the northern plains of Mars. In this image, we see strong Fe-rich olivine (yellow) and high calcium pyroxene (HCP, blue) signatures in the ejecta near the crater … Continue reading

THEMIS: Ice-rich mantling in Utopia crater
THEMIS Image of the Day, April 16, 2019. This false-color VIS image shows a crater located in Utopia Planitia. The crater’s interior shows ample evidence for an ice-rich mantling material that has slipped and slumped away from the crater’s upraised … Continue reading

HiRISE: Frost-covered dunes
Frost-covered dunes. Sprinkled with hopes and dreams, no less. This is a relatively new monitoring site that seems to have heavy carbon-dioxide snowfall. HiRISE Picture of the Day archive [More at links]

HiRISE: For your consideration
For your consideration. An alien landscape with dust devil streaks and craters slowing fading away into the mists of time. A twilight zone of geology, if you will. (Features like this are often called “thumbprint terrain”.) HiRISE Picture of the … Continue reading

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

THEMIS: Subdued northern plains craters
THEMIS Image of the Day, October 10, 2018. This VIS image shows the margin and ejecta surrounding two craters located in the northern plains. The rim and ejecta are very subdued compared to craters elsewhere in the same region. The … Continue reading

Crustal dichotomy: First a giant impact, then a superplume at the antipode
The result of collaboration between researchers at UC Berkeley, USA and the Institute of Earth Sciences, Taiwan, suggests a two-stage process to explain the martian crustal dichotomy. The dichotomy is a 5-km elevation difference between the northern and southern hemispheres … Continue reading
