HiRISE 10K: Lava Flows in Daedalia Planum
To the southwest of Arsia Mons in Daedalia Planum, wide lava flow units emanating from the volcano coalesce to form a vast volcanic plain.

HiRISE 3D: An Impact Crater on the Northern Plains
The best way to end a week of 3D images? With a classic impact crater image.

A Layered Mound in Claritas Rupes
Also available in Context Camera data, the objective of this observation is to examine a layered mound near a curved valley. Claritas Rupes is a 924-kilometer long scarp to the southwest of Solis Planum, and part of the Claritas Fossae unit. The term “rupes” is used in planetary geology to refer to escarpments and is the Latin word for “cliffs.”

HiRISE 8K: Layers Exposed in the Walls of an Impact Crater
Partway down from the crater rim is a prominent bright layer of bedrock. These layers must correspond to different types of rock that were deposited as nearly flat-lying sheets.

HiRISE 3D: A Potential Future Mars Landing Site in Melas Chasma
Another anaglyph that shows off the power of HiRISE resolution needed for hazard assessment for future missions.

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.

HiRISE Epigrammata
“As an endless dream it went on…to find all gods dead, all wars fought, all faiths in man shaken….”
—F. Scott Fitzgerald, “This Side of Paradise”
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
When an observation title kinda says it all.

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.
