HiRISE 3D: Near a Flow Edge
This crater is oddly nested in a shallow depression and is near the edge of a (mud?) flow boundary. Maybe flow surrounded the crater, then partially drained?

HiPOD 1 September 2022: Impact-Related Deposits and Flows
The goal of this image is to observe how surface flow patterns in the area vary with distance from a proposed parent crater. This is one of several flow feature observations being suggested in the vicinity of a small (under 5 kilometer) well-preserved crater to the east of this locale. Shalbatana Vallis likely was the shoreline of an ancient lake and is the word for Mars in the Akkadian language.
HiRISE 8K: Mounds of the Martian North Pole
This image shows apparent mounds on residual ice observed in association with dune migration. (See link for full cutout.)
HiRISE 3D: A Certain Exquisiteness
These sleek formations are part of the North Polar layered deposits. This area has not been well-observed by previous missions.

HiPOD 31 Aug 2022: Of Light and Dark in Mawrth Vallis
The objective of this observation is to help us determine the relationships of a “spectrally bland” dark-toned cap unit visible here, and at other locations on Mars (e.g., Nili Fossae, Oxia Planum etc.). At this location Context Camera images show that the dark materials coat both the ejecta lobes of a nearby well-preserved crater as well as the surrounding surface.

HiRISE 4K: Layering in Western Arabia Terra
Arabia Terra has lots of layering that is always a pleasure to view. (See link for full cutout and additional information.)
HiRISE 3D: A Weird Knob
This dome-like feature is similar in shape to another feature imaged earlier. In this case it doesn’t appear to involve an impact crater. An anaglyph helps to perform analysis and comparison.

HiPOD 30 Aug 2022: Embayed Mounds near Huygens Crater
The objective of this observation is to examine a group of mounds that are surrounded by lava flows. These flows appear to have stopped short of the mounds. These are also hummocks from the rim of a buried crater and understanding how this burial happened is of significant interest for us. Huygens is to the west of this observation.

HiRISE 3D: A Double Crater on the Cerberus Plains
Here we see a double crater with radial ridges due to ejecta interactions on the Cerberus Plains. Probably due to a binary asteroid, as the larger crater is too big to realistically be a secondary.

HiPOD 29 Aug 2022: A Tale of Two Strata
The material to the east and west sides of this image exhibit different patterns of erosion. To the west (left), there is thin layering of fairly uniform thickness that is perhaps laterally discontinuous. Is this fluvial sediment, wind-blown sediment or something else? This scene is in western Lucus Planum and is part of a region called the Medusae Fossae Formation.

HiRISE 8K: Mounds and Ridges in Aurorae Chaos
Are these fascinating formations the result of faults or dikes? Aurorae Chaos is a region of chaos terrain on Mars at the eastern end of the outflow channels from Valles Marineris into Chryse Planitia. (See link for full cutout.)
HiRISE 3D: A Layered Knob in Northwest Hellas Planitia
This butte in northwest Hellas Planitia shows inverted fractures, potential layering and light-toned outcrops. ’Tis a beaut!

HiPOD 25 Aug 2022: Cliffs of Ice
The bright material on the cliff face is icy and is preserved only because the cliff points away from the equator, so it is shaded most of the time. Faint bands on the cliff might indicate layers in the ice that record different climate conditions.
HiRISE 4K: Holes
The objective of this observation is to examine a hole in the terrain that will give us a cross-sectional view of the thick mantle in this region. There are also hints of visible ice. (See link for full cutout.)

HiRISE 3D: A Possible Landing Site in Mclaughlin Crater
This was imaged for the Mars 2020 mission when this crater was a potential site. It’s in the southwest portion of the landing ellipse, and has layered clays and carbonates.

HiPOD 24 Aug 2022: On Bond Crater’s Northern Slope
This image shows (part of ) a 6-kilometer crater located on the northern slope of Bond Crater. Pole-facing gullies have eroded the northern slope of this small crater, located just west of where Uzboi Valles emanates from Bond and continues in a northerly direction.
Bonus HiRISE 3D: Possible Sulfate-Rich Terrain in Northeast Syrtis Major
Sulfates have been discovered beneath the northeast margin of the Syrtis lava flows and HiRISE DTMs are required to differentiate sedimentary vs volcanic origin.

HiRISE 3D: Dune Topography of Holden Crater
This was originally requested to construct a DTM for possibly active dunes near potential landing sites for the Mars 2020 mission. This underscores how needed HiRISE is for mission support.

HiPOD 23 Aug 2022: Colorful Rocks Exposed in a Fresh Impact Crater
Rocks of several different colors are exposed in this crater’s walls; they are undergoing erosion into finer-grained debris that travels downwards and accumulates in small fans on the crater floor. The rocks exposed on the eastern crater wall appear bluer in enhanced color than the redder rocks of the southern wall.
HiRISE 10K: Diverse Exposures of Bedrock Associated with Massifs Outside Hellas Planitia
This observations was requested to help determine the origins of the diverse materials exposed in a number of massifs associated with the Hellas impact basin. (See link for full cutout and additional info.)
