HiPOD 13 Jul 23: Dunes in Tyrrhena Terra
The objective of this observation is to examine a few dunes near small craters. If any movement or other changes occur, one can easily tell because the dunes are associated with these small craters. This scene can be found in a Context Camera image. Tyrrhena Terra is northeast of the Hellas impact basin and covers 2,300 kilometers at its broadest extent.

HiRISE 4K: Slopes in East Melas Chasma
Potential recurring slope lineae was detected in earlier images, perhaps associated with the sulfate-rich layers we find here.

HiRISE 3D: Crater vs. Graben!
Was a graben minding its own business when the crater was formed? One goal is to measure the erosion of one rim compared to the other.

HiPOD 12 Jul 23: A Silica-Rich Deposit Northwest of Ariadnes Colles
CRISM spectra data indicate the presence of silica deposits in this region. The geologic context is key for determining the origin (whether wind-driven or bedrock) of these deposits, and their distribution with the crater. This could give insight into hydrothermal processes in Eridania Basin.

HiRISE 3D: A Rocky Area in Ausonia Cavus
This locale is bright in nighttime infrared, and it might be a source for Dao Valles.

HiPOD 11 Jul 23: A Ridge and Channel through Ice Rich Terrain
A sinuous ridge and associated channels emerge from ice-rich material, which has subsequently been disrupted by a young impact crater. The sinuous ridge appears to pay little regard to topography, so high-resolution analysis of topography and stratigraphic relationships to young ice deposits will allow us to better understand whether it formed by subaerial or subglacial water flows, or as a moraine.
HiRISE 3D: A Depression in Osuga Valles
This image was requested to fill in a gap in mosaic coverage of this area.

HiPOD 10 Jul 23: An Infilling of Lava?
This observation was requested to support an ongoing SHARAD investigation in this region. More coverage of the surface will assist in determining what is infilling this low-lying region.

HiRISE 10K: Deposits in Libya Montes
Often times, a very simple rationale for obtaining an image is the best: we acquired this observation to get more coverage of colorful bedrock.

HiPOD 7 Jul 23: Banding on the Wall
Our objective is not just to image the banding, or perhaps layering, exposed on the crater wall, here, but also to capture a full resolution view of the variety of textured surfaces inside and outside the crater. At Context Camera image scale, all of these surfaces are fairly rugged and pitted. Are some of these lithified sediments and regoliths? Is there any hint of lava or intrusive igneous rock here?

HiRISE 4K: Dark Dunes to the South of Iani Chaos
Our goal with this observation is to re-image these dunes to see if they have moved since an image acquired in 2012 and to get a higher-res view of their morphological features.

HiRISE 8K: A Constriction in Kasei Vallis
This image was acquired in order to complete stereo mosaic coverage of this constriction, which was likely carved by lava.

HiRISE 3D: Convoluted Folds in Light-Toned Sulfates along Ius Chasma Floor
This was our HiRISE Image of the Day, and we could not resist showing the 3D version, which can help us understand how the folds formed.

HiPOD 6 Jul 23: Cool and Convoluted
HiRISE and CRISM images to west of this locale show these are very cool and convoluted folds in sulfate deposits along the floor of Ius Chasma. CRISM data shows lots of subtle mineral changes so we need high resolution to see any corresponding variations in shape. Part of Valles Marineris, Ius Chasma is about 938 kilometers long.

HiPOD 5 Jul 23: South Polar Troughs
This image was requested through HiWish to map and quantify the dimensions of troughs overlying the massive carbon dioxide ice deposit in the South Pole of Mars. These troughs are likely crevasses formed from glacial flow. Their size and shape provide important information regarding the thickness and size of the polar carbon dioxide inventory, which is in turn important for governing Mars’ climate.

HiRISE Mars 4K (NASA): This Bed o’ Dunes
Matara Crater is a favorite of ours to image owing to the massive and gorgeous sand sheet that dominates the floor. (This is a non-narrated clip with ambient sound.)
HiPOD 4 Jul 23: Mesas Eroding out of a Mawrth Vallis Plateau
These mesas contain bright-toned material which have been found to be clay-bearing in other mesas with both HiRISE and CRISM data. These regions of bright-toned material are layered down to the meter scale and are heavily fractured, reminiscent of the clay-bearing deposits at Mawrth Vallis.
