HiRISE 3D: Gullies in a Crater in South Aonia Terra
This region has been observed three times by the Mars Orbiter Camera and shows a set of gullies with dark edges apparently originating from layers at a crater edge.

HiPOD: Dune Monitoring in Renaudot Crater
This observation was requested as part of an imaging campaign to monitor frost deposition, evolution, and sublimation. The campaign is designed to capture the onset of seasonal frost, which means images taken near the polar hood have very high incidence angles that are important. The image can also be used for detailed surface measurements.

HiRISE 3D: Branching Fluvial Deposits in Aeolis Dorsa
Observations like these may suggest that Aeolis Dorsa is a paleo-coastal region which may be an important site for exploration in the future.

HiPOD: Climbing Dunes of Aonia Terra
The dunes in this observation appear to climb out of an impact crater and merge with those in the plains to the north. The northeast of the part of the image overlaps with another HiRISE image we acquired in 2007. The crater also has gullies that are partially covered by the dunes.

HiRISE 3D: A Well-Preserved 6-Kilometer Impact Crater South of Eos Chasma
This anaglyph covers the northern part of the crater. Though out of frame, there is also a wide channel that possibly leads to (or from?) the crater.

HiPOD: Dunes in Lyot Crater
This stunning image was obtained to monitor frost deposition, evolution, and sublimation. This observation will also be used for detailed surface measurements. Lyot is a large peak ring crater in the Vastitas Borealis region of Mars, and is about 236 kilometers in diameter and is also the deepest point in the Northern Hemisphere of the planet.

HiRISE 3D: A Crater Rim Exposing Bedrock
With this anaglyph, we can then create a digital terrain model mosaic of especially well-exposed layered bedrock.

HiPOD: Dunes in Nectaris Montes
Sand dunes in Valles Marineris can be impressive in size, with steep slopes that seem to climb and descend. An enhanced-color cutout shows some of these on the slopes of Nectaris Montes within Coprates Chasma.
The brighter bedforms are inactive while the bigger dunes move over the landscape, burying and exhuming the surface.

HiPOD: Gullies in a Crater in Terra Cimmeria
The objective of this observation is to examine gullies in a crater. Images like this help to increase our inventory and understanding of Martian gullies so that perhaps improved models can be constructed. This particular image is special because the gullies begin at two different levels.

HiPOD: Slope Streaks in Arabia Terra
This image shows numerous light-toned streaks that seem to flow along the ground surface. These streaks form when dust and possibly sand-sized particles avalanche downhill.
Now it’s our turn!

HiPOD: Exposed Bedrock in Eos Chasma
This 47-kilometer (29 mi) diameter crater in Eos Chasma exhibits a central uplift comprised of well-exposed fractured bedrock. HiRISE color imaging reveals fine-scale details in addition to two other key features observed at crater central uplifts.

Bob King was a respected member of the HiRISE team, who passed away in 2022. We are privilged to share of one his many accomplishments in appreciation of his memory.
Thank you, Bob.
HiPOD: Pits near Medusae Sulci
This image shows numerous C-shaped depressions within the Medusae Fossae Formation, which is interpreted to consist of volcanic ash. The center of most depressions contains a small hill, which provides a vital clue to how the depressions formed.
HiPOD: The Oldest Sedimentary Rocks on Mars
Some of the very oldest sedimentary rocks on Mars, perhaps the best places to search for signs of ancient life, may be exposed in the deeply eroded rim of the giant Hellas impact basin. The study of such geologic strata may inform the early evolution not only of Mars, but also Earth, where such ancient rocks are poorly preserved.
HiPOD: Polar Protodunes Emerge
In Western Olympia Undae, a region along the high polar latitudes of Mars, young windblown systems are emerging beneath the cliffs of the North Polar layered deposit. Persistent downslope winds, coupled with an ample supply of sand, create ideal conditions for the development of new bedforms near their sand source.

HiPOD: Possible Smectite-Rich Terrain North of Her Desher Vallis
Coverage by the CRISM instrument (also on MRO) of this region of interest hints at a possible outcropping of smectite, which is a clay mineral. This composition is not yet seen elsewhere in the stratigraphy of the area. Color and multispectral analysis will also help us to investigate this geological unit.
