HiRISE: Hale Crater ejecta

Posted on March 27, 2018 by rburnham

Hale Crater ejecta with pits and rocky outcrops. This observation will help give coverage of Hale Crater ejecta for mapping studies. The ejecta is sparsely covered, and this particular footprint has what appear to be rocky outcrops near the extent … Continue reading →

HiRISE: On the intricacies of carbon dioxide ice

Posted on March 23, 2018 by rburnham

On the intricacies of carbon dioxide ice. Measuring the mass balance of what we call the residual South Polar cap (RSPC) has important climatic implications. This image was requested to detect any vertical changes compared to earlier observations. Beautiful Mars … Continue reading →

HiRISE: The exposed exterior of a modified crater in Tantalus Fossae

Posted on March 22, 2018 by rburnham

The exposed exterior of a modified crater in Tantalus Fossae. Many craters in this area have been extensively modified, but few are sitting on the edge of a graben like this. This position exposes parts of the crater exterior and … Continue reading →

HiRISE: Dune erosion and streaks

Posted on March 21, 2018 by rburnham

Dune erosion and streaks. One of the many seasonal images we take to detect changes. In this case, we want to quantify the process of erosion driven by sublimation on the dunes. (Sublimation is the process of going directly from … Continue reading →
