HiPOD 30 Jun 22: A Survey of Wislicenus Crater
Previous images appear to have northwest- and west-facing examples of recurring slope lineae (RSL). Additional images like this one can confirm if this is a good RSL candidate site. Wislicenus Crater is about 140 kilometers in diameter, and is located in Noachis Terra. In addition to RSL, the light-toned rock we see might be associated with hydrated minerals like sulfates that indicate a possible ancient water environment.
HiPOD 29 Jun 2022: Slope Failures in Tempe Terra
Slope failures in the form of faulted blocks suggest modification of materials within this ancient basin, possibly related to recent glaciation. Studying the possible triggers and dynamics of the slope failures including 3D analysis of the geometry of the slope failures will aid in understanding the history of sedimentary, glacial, tectonic and fluvial processes in the basin.

HiRISE 8K: All along the Slopes
Previous images that we acquired showed recurring slope lineae (RSL) on northwest and west-facing slopes. (See link for full cutout and additional information.)

HiRISE 3D: A Small Delta or Fan
Delta or fan deposits indicate past water activity. HiRISE can resolve sedimentary characteristics such as layering that cannot be resolved by other camera experiments.

HiPOD 28 Jun 2022: A Patchy Outcrop
This observation targets patchy exposures of light-toned outcrops. These materials may be chloride bearing and if so, this might give us a time frame for the formation of chloride deposits in this region. Erosion appears to have cut through the entirety of the light-toned materials in these outcrops, which should allow probing of the stratigraphic context, thickness and any possible internal layering of these materials.
HiRISE 3D: Troughs and Ridges in Chryse Planitia
Wide troughs with a narrow ridge running down the middle. How did these form? (The black bar represents unrecoverable data that could not be processed.)

HiPOD 27 Jun 2022: Ridges and Troughs in Crater Ejecta
Our science goal is to determine the nature of ridges and troughs in crater ejecta. In this image footprint are various examples of modifications to the ejecta. Some parts seem to have formed blisters that broke open into ridges and troughs. But, some terrain next to it did not.
HiPOD 24 Jun 2022: The Devil’s Tower of Chryse Planitia
This stratified butte contains bright-toned material at its top and base that are clay-bearing according to CRISM data. These regions of bright-toned material are layered down to the meter scale and are heavily fractured, reminiscent of similar clay-bearing deposits at Mawrth Vallis. Correlation of these deposits is possible with HiRISE images.

HiRISE 3D: Layering in Western Arabia Terra
Ahh, lovely Arabia Terra, whose wonderful and complex landforms never fail to make excellent 3D images! This one merits a rare double cutout post.

HiPOD 23 Jun 2022: Young Fluvial Channels in Margaritifer Terra
Margaritifer Terra is the most impressive water-modified landscape on Mars that preserves the highest density of valley networks on the planet.
HiRISE 4K: Dark Fans in East Coprates Montes
In Context Camera images, there appear to be candidates here for very large examples of recurring slope lineae, so our smaller footprint can take a better look to help us determine this. (See link for full cutout and additional information.)
HiRISE 3D: Embayment around a Ridge
Here, there appear to have been two embayment stages of lava, which is unusual. Worth a look to understand thicknesses and sequence.

HiPOD 22 Jun 2022: Flooded Impact Craters in Hebrus Valles
This observation shows channels of uniform width suggesting more persistent flows eroding into and around two impact craters, each about two hundred meters in diameter. This complex geology may be the result of formation in volcanic terrains as fluid flows erode into basalt and interbedded ash or sediment layers.
HiRISE 3D: A Mesa in Utopia Planitia
Our science goal is to determine superposition relationships between the mesa, fractures, pitted mounds and flows in this area.

HiPOD 21 Jun 2022: A Complex Geologic History of Aram Chaos
This 280-kilometer diameter crater center has experienced a long history of water activity. Within the crater is a heavily faulted and fractured terrain called Aram Chaos that consists of darker volcanic rocks that were disrupted as a result of water and/or magma withdrawal in the subsurface.
HiRISE 3D: Megabreccia in the Northeast Syrtis Region
The region of interest contains megabreccia that may be a breccia dike. However, 3D context is needed to determine the exact nature of this exposure. It is important to determine this to understand the impact dynamics that created the Isidis basin.

HiPOD 20 Jun 2022: Spring Fans and Polygons
Spring activity is visible as the layer of translucent dry ice coating the surface develops vents that allow gas to escape. The gas carries along fine particles of material from the surface further eroding the channels.
HiRISE 3D: Tongue-Shaped Flows
The objective of this observation is to examine tongue-shaped flows and gullies in on the west wall of a crater. The flows are somewhat hollowed out, like they have lost most of their ice.

HiPOD 17 Jun 2022: Athabasca Valles
This image is of the upper part of Athabasca Valles, a very young flood channel on Mars that might have been carved by a flood of lava instead of a flood of water. “Young” is a relative term: the flood that carved the channel took place millions, perhaps tens of millions of years ago. Erosion has dug into the upstream sides of the high-standing parts of the landscape and produced boat-like tails on the downstream side.
HiPOD 16 Jun 2022: Cone Cluster Chaos!
It has been considered by scientists that chaotic terrain could have been created by magmatic processes and that small cinder cones on Mars, like these in Baetis Chaos, could be the cause of those processes. Heat from these different activities could have melted the subsurface ice that released vast amounts of water creating chaotic terrain.
