HiPOD 29 Aug 23: Dipping Layers in Centauri Montes
The objective of this observation is to examine some sets of dipping layers along a mesa in Centauri Montes. Pictures like this will help us determine the horizontal extent of these features which are supposed to be the remains of an ice-rich unit that was widespread in the past.

HiRISE 3D: The South Wall of East Candor Chasma
An eventual digital terrain model from this stereo pair will support structural and geologic mapping in the area.

HiPOD: A Possible Clay-Rich Deposit
The nearby Nirgal Vallis locale exposes a clay unit in its valley walls. This observation aims to determine if this unit can be determined elsewhere in the region, such as in excavations in nearby craters. This crater likely has nice bedrock exposures, as visible in THEMIS and Context Camera data, and an overlapping CRISM image indicates a clay exposure.

HiRISE 3D: Crevasse-Like Features
This request was made to obtain a stereo pair for an eventual digital terrain model, and to see if any changes occurred since a previous image.

HiPOD 24 Aug 23: Boulders inside of Pits
The objective of this observation is to determine the nature of boulders sitting inside of pits along the edge of a mesa. Wind may have blown away the material around the boulders. This image will also include exposed layers in the mesa wall and gives us more examples of these features from a previous HiRISE image at a nearby location.

HiRISE 3D: Daedalia Planum Lava Flows
There is something very Tattooine-esque about this sinuous ridge...

HiPOD 23 Aug 23: HiPOD: A Scarp in Pavonis Mons
HiRISE images of other steep-sided edifices within the Pavonis Mons fan-shaped deposit are providing new insight into volcano-ice interactions that occurred as the deposit formed. Context Camera images reveal several shapes not commonly visible in the other images; more detail would be helpful in distinguishing between hypotheses for the development of this plateau.

HiRISE 3D: The Floor of Uzboi Vallis
This footprint crosses a 200-meter tall scarp and a 3D pic will be useful to study the deposits along the southern edge of the cliff.

HiPOD 22 Aug 23: Candidate Lake Deposits
In this observation, we want to take a look at candidate lake deposits fed by alluvial fans. High resolution will help us to check for layers, layer tilts, to test this lacustrine hypothesis. Tilts more than approximately 2 degrees suggest not lacustrine, but rather distal alluvial origins.

HiRISE 3D: A Fissure near Cerberus Fossae
Stereo imaging of this location will provide analysis of the surface slopes and the volume of material that was eroded along the edge of the fissure.

HiPOD 21 Aug 23: Possible Breccias in Nirgal Vallis
A Context Camera image showed light-toned blocks that may be consistent with the megabreccia basement, which is possibly exposed here as well in Valles Marineris. HiRISE had no previous coverage here, something that makes for a good HiWish target rationale. Nirgal Vallis is 610 km long and is named after Nergal, the Babylonian god of war and counterpart to the Roman god of war Mars.

HiPOD 18 Aug 23: Chaos in Chryse
Our science goal for this observation is to document stratigraphic relationships between chaos blocks and adjacent geologic units. With a stereo pair, we can create a digital terrain model to interpret superposition relationships in this scene. The general shape of “chaotic terrain” is steep-sided mesas in close proximity. In planetary nomenclature, the descriptor term “chaos” means “distinctive area of broken terrain.”
HiPOD 17 Aug 23: HiPOD: Diverse Minerals in Coprates Chasma
This image shows the southern wall of Coprates Chasma, in the equatorial canyon system of Valles Marineris.
In enhanced color, the varying colors—shades of white, cyan, and purple—are suggestive of multiple minerals being present within the bedrock, indicating a complicated geologic history, possibly involving alteration by water.
HiPOD 16 Aug 23: Icy Flows
The surface of Mars is littered with examples of glacier-like landforms. While surface ice deposits are mostly limited to the polar caps, patterns of slow, viscous flow abound in many non-polar regions of Mars.
Streamlines that appear as linear ridges in the surface soils and rocky debris are often exposed on top of infilling deposits that coat crater and valley floors.

HiPOD 15 Aug 23: From Low to High Channels
This image shows the transition from a regular channel to an inverted channel in Arabia Terra. The channel was once flowing with water that carved down into the bedrock to produce a depression.
HiPOD 14 Aug 23: Light-Toned Materials along the Floor and Walls of Ius Chasma
The light-toned deposits here are thinner and occur along both the floor and walls, as we see in this HiRISE image. Additionally, the sulfates are mixed with other minerals like clays and hydrated silica.
HiRISE 10K: Light-Toned Mounds in Ganges Chasma
This formation of light-toned mounds on the floor of Ganges Chasma have been shaped by two erosional processes: landslides and wind.

HiPOD: A Crater Intersecting a Ridge
This wrinkle ridge east of Elysium Mons is a tectonic feature likely created by a thrust fault. A small crater intersects the ridge. If the crater formed before the ridge, measurements of the crater’ shape deformation can help estimate the amount of surface displacement of the fault.
