The Canyon Floor in East Coprates Chasma
The walls (both south and north of this site) potentially expose pristine crustal material. This is an area of interest that could be accessed and is within a potential future rotorcraft landing site.

NASA’s Hubble, MAVEN Help Solve the Mystery of Mars’ Escaping Water – Scientists know that over the last 3 billion years, at least some water went deep underground, but what happened to the rest?
HiRISE 4K: Possible Clays near Margaritifer Chaos
The existence of clay minerals is especially interesting on Mars since we want to know under what conditions these minerals formed. Could it have been the presence of water?

HiRISE 3D: A Possible Future Landing Site in Coprates Chasma
Anaglyph images from HiRISE provide additional detail to characterize hazards within a possible landing ellipse.

Irregular Graben Features
The graben in this image contains an unusually tall cone with very even sides, and the surrounding terrain is darker in the direction of prevailing wind. This observation could bring out some of the detail around this unusual feature and show possible changes that have occurred over the last ten Earth years in case this area is thermally active.

HiRISE 3D: To Measure Heights and Widths of Raised Ridges in a Sedimentary Deposit

On Thick Ice
In this fascinating image, we see fractured mounds on thick carbon dioxide ice that may be diapirs or deflation over subglacial topography. The pits may show signs of ongoing collapse. A diapir is a relatively mobile mass that intrudes into preexisting rocks. Diapirs commonly intrude vertically through more dense rocks.

HiRISE 3D: Gullies!
These gullies on the wall of an impact crater look great in Context Camera data, and now we take an even closer 3D look.

Resistant Material in Olympus Mons Aureole Ridges
The question of how the Olympus Mons aureole formed has wide-ranging implications for Mars paleoclimate, including whether a northern ocean existed. The properties of the resistant material exposed within aureole blocks can help test the merits of competing hypotheses for the aureole’s formation.

Tangential Craters within Ptolemaeus Crater
This image shows two small craters, just touching on their rims, in the much larger Ptolmaeus Crater, which is located in the Martian Southern Hemisphere. These craters are called “tangential craters.”
The more degraded and filled-in crater is approximately 3 kilometers in diameter, and there is an unusual feature near the center.

Gigas Sulci
A sulcus (or sulci, plural) is defined as “subparallel furrows and ridges.” This is a purely descriptive term for landforms that could have a variety of origins.
At this location appears to be a graben (which is a fault-bounded valley) on a large scale, and locally (such as in this image) became a vent region for lava flows.

HiRISE 10K: Layers in Western Arabia Terra
Extensive erosion in this region has exposed numerous rock layers. Layers are visible on the flanks of some hills and on the basement (the lowest rock unit) between the hills.

HiRISE 3D: Inverted Channel and Possible Lake Deposits
The former channel had material that was more resistant to erosion than the surrounding terrain, so now stands in positive-relief in our image.

Phyllosilicate-Rich Terrain in the Ejecta of an Impact Crater
The cutout shows the plains adjacent to the crater’s northwestern rim in enhanced contrast, highlighting the range of compositions sampled by the crater that exhibit a range of colors. Phyllosilicate-rich materials on Mars most commonly have relatively orange colors, whereas some of the bluer material visible here may have been less altered by interaction with water.

HiRISE 3D: Potential Fan Deposit in Crater near Mawrth Vallis
A fanlike deposit (visible in CTX) emerges from a valley on an impact crater wall. Detailed study of this fan could help in understanding the depositional environment and hydrologic system in the region.

Colorful Terrain Southwest of Dawes Crater
In between the craters and sand cover, the bedrock here shows a range of colors, likely reflecting a range of rock compositions that were perhaps jumbled up by the Dawes and other nearby impacts that occurred over Martian history. The enhanced color cutout shows some green/blue blocks that may contain the igneous minerals pyroxene or olivine.

Delta or fan deposits indicate past water activity. HiRISE can resolve sedimentary characteristics such as layering, stratigraphic relationship to the surrounding geologic setting that cannot be resolved by other camera experiments.
