HiRISE 8K: Especially Bright Materials in Candor Chasma
A Context Camera image shows especially bright materials here, and possibly the contact relations between interior deposits and the outer wall rocks. (See link for full cutout and additional information.)
HiRISE 3D: Lovely Gullies all along the Slope
These nice gullies appear in deep shadow in a previous image, but they are prominent and sharp here.

HiPOD 20 Oct 22: The Tale of a Retreating Scarp
This scene on the north rim of Secchi Crater shows a curious depression with zig-zag walls. Some of the linear ridges on the floor of this feature are aligned with them.
HiRISE 4K: Noachis Region Clays
CRISM data shows the presence of iron/magnesium and aluminum clays here, so we want to understand the types of rocks these clays occur in, and the stratigraphic relationship between them. (See link for full cutout.)
HiRISE 3D: Layering in Western Arabia Terra
The layered deposits in this region always look fantastical in 3D! This will eventually led to a digital terrain model to help measure bed thickness.

HiPOD 18 Oct 22: A Crater in Scalloped Terrain
Sublimation (ice vaporizing without passing through a liquid stage) is an important process affecting water ice in the mid-latitudes of Mars. This might be responsible for creating two different landforms: scalloped depressions and expanded craters.
HiPOD 13 Oct 22: A Sinuous Ridge in Aeolis Dorsa
This beautiful and prominent snaking ridge and its attendant landforms might be fluvial in origin, perhaps inverted river channels. Our science goal is to examine the details of the sedimentary structure, and seek better understanding of the percentage of fluvial sediment versus the substrate. Aeolis Dorsa lies between Zephyria and Aeolis Planum.

HiRISE 3D: 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 is within a potential future rotorcraft landing site.

HiRISE 4K: Wrinkle Ridges in East Meridiani Planum
This wrinkle ridge crosses through a mound of layered material and is exposed by erosion. This observation is an excellent opportunity to look at the internal structure of a wrinkle ridge. (See link for full cutout and additional info.)
HiRISE 3D: Debauched Channels!
This rationale was interesting to see: “Channels debauching into a [ancient former] pond in Orson Welles Crater.” What led them astray?
(The term is actually "debouch". But a typo can still make for a good rationale to take a picture.)

HiPOD 12 Oct 22: Central Uplift of Well-Exposed Taytay Crater
A previous image revealed the presence of possible eroded impact melt-bearing breccias (large, sharp-angled fragments of cemented rock) that embay the central uplift of Taytay. Olivine rich megablocks and terraces appear to be abundant here. If we are to find clays associated with the melt-bearing breccias, this would be one of the better places to look for them with the CRISM instruments.
HiPOD 11 Oct 22: Exposed Bedrock in Jones Crater
A survey based on HiRISE and Context Camera data indicates that this crater is among the best preserved ones on Mars. It retains what is believed to be primary crater deposits, ie., crater-related pitted materials such as volatile-rich impact melt-bearing deposits. Jones is about 94 kilometers in diameter and was named after English astronomer Harold Spencer Jones (1890–1960).

HiRISE 3D: A Nilosyrtis Region Crater with Asymmetric Walls
This (geologically) fresh impact crater with concentric crater fill an asymmetric walls has some interesting glacial stratigraphy.

HiPOD 10 Oct 22: At the Mouth of a Valley Network
This observation targets a region of light-toned materials that are located within a complex region at the mouth of a highlands valley network. Several interesting landforms include: 1) an outcrop with tabular ledges (layering?); 2) a cluster of low, sinuous outcrops of darker-toned material (inverted channel deposits?); 3) a region of the light-toned material containing unusual ridges of unknown origin.
HiPOD 8 Oct 2022: A Mesa in Noctis Labyrinthus
Heavily eroded, with clusters of boulders and sand dunes on its surface, this layered mesa is probably comprised of sedimentary deposits that are being exhumed as it erodes. The layers themselves are visible as faint bands along the lower left edge of the mesa.

HiRISE 3D: Lonely Little Impact
Here we see a small crater about 125 m in diameter on the bright polar ice cap. Originally seen in CTX image , our follow up is needed for accurate diameter measurements to better constrain the age of this deposit.

HiPOD 6 Oct 2022: A Mesa in Chryse Planitia
The eastern flank of this mesa has already been imaged by HiRISE. The CRISM instrument has detected clays at the western end, but we lack the context for this measurement. Similar HiRISE images of mounds around Chryse Planitia have revealed stunning and complex meter and decameter-scale stratigraphy, indicative of widespread regional processes.
