The Bedrock of a Crater

The Bedrock of a Crater
This stunning image features exposed bedrock in the southwestern part of an impact crater that is located within another crater. With a stereo pair and an eventual digital terrain model, we can examine the stratigraphy of the bedrock in greater detail. This location is in Thaumasia Planum, directly south of Valles Marineris.   
Craters in Olivine

Craters in Olivine
CRISM multispectral mapping data show strong potential olivine signatures in a bright unit in Solis Planum that is here penetrated by a few impact craters. This potentially exposes compositional stratigraphy. The occurrence of olivine on the surface of Mars has posed for researchers a fascinating question of how long it has been there and what that means about Martian climate history.  
Downwind of the Barchan Dunes

Downwind of the Barchan Dunes
The science rationale for this beautiful image is to look for and measure seasonal changes due to wind (aeolian) processes since an earlier image we acquired. High flux dunes upwind, but how do they compare downwind? The “horns” of these barchan dunes point in the direction of the prevailing wind.   
Valley Networks of Mars

Valley Networks of Mars
This image features dense, highly branched valley networks, two branches of which seem to originate in circular features: ancient crater floors, or something else? The floors of the valley networks are presently filled with north-south aligned dunes that look very pretty when lit up in afternoon light.   
A Curious Case of Positive-Relief

A Curious Case of Positive-Relief
This observation captures a curious, fractured feature on the South Polar layered deposits: is this an active feature? We saw this in a much earlier image, but it was very hard to find changes with such an extreme difference in lighting direction. This will be part of a series to reproduce the lighting and compare any changes.
