HiRISE 8K: Dune Monitoring in Kunowsky Crater
The rationale for this observation is as straight-forward as it gets: to obtain an image for change detection measurements to compare with an image from a previous year. (See link for full cutout and additional info.)
HiRISE 3D: Landforms in the Northeast Syrtis Major Region
Here we can check the relationship between layered sulfates and paleotopography: is it draping or onlap? HiRISE resolution can trace the layers and fit the bedding orientations.

(Onlap defintion: the arrangement of strata deposited on the floor of an advancing sea during its advance.)
HiPOD 18 Aug 2022: A Crater near the Opportunity Landing Site
This lovely impact crater shows distinct boulder tracks on the right-hand side, suggesting recent (perhaps ongoing?) rockfalls. There is no sign of recurring slope lineae, but if any were to happen in this region, this would be a likely location. One of our goals is to take a few monitoring images and track any changes.

HiClip mini 4K: The Textures of a Crater
This observation focuses on the southern portion of an interesting elliptical impact crater on Mars. Mars. (This is a non-narrated clip with ambient sound.)

HiRISE 4K: The Serenity of the Dunes
This scene is located at the southern end of the massive Lyot Crater, a large peak ring crater in the Vastitas Borealis region of Mars. (See link for full cutout and additional info.)
HiRISE 3D: Monitoring Gullies in Russell Crater
With this image, we can search for gully activity on a new zone of a major dune in Russell Crater.

HiPOD 17 Aug 2022: About a Dune
There are multiple dunes in this observation worth looking at! The barchan dunes might have their source in Chasma Boreale in the northern polar region of Mars that we have seen in earlier HiRISE images. Barchan dunes are notable for their croissant-shaped appearance. Our goal is to continue monitoring over several years to look for changes, the rate of changes, as well as the texture of these stunning dunes.

HiRISE 3D: A Lonely Crater in Gorgonum Chaos
An earlier interpretation suggests this region to be an ancient inland sea. But could it be volcanic? Our observation can help to further investigate the origin of this region.

HiPOD 16 Aug 2022: On the Beauty of Martian Slope Streaks
Slope streaks are typically caused by the displacement of material, perhaps from a falling rock or bolder, that exposes the darker subsurface to the harsh Martian sunlight. Streaks generally fade over long periods of time. These streaks are notable not only for their wonderful shapes, but their interesting position on the rim of a small and ancient impact crater.

HiRISE 3D: Hills in Coprates Chasma
These two well developed cones, probably Martian equivalents of cinder cones, are part of a wider volcanic field in Valles Marineris.

HiPOD 15 Aug 2022: Radial Ridges on a Crater Floor
The objective of this observation is to determine the nature of a group of short radial ridges on an old crater floor. These may be inverted channels from previous glaciers in the crater. This scene is also visible in a Context Camera image.

HiPOD 11 Aug 2022: A Pit in a Crater Floor
This apparent collapse pit occurs within the floor of a much larger crater in the Southern Highlands of Mars. The lozenge shaped pit has sharp edges, and a small crater at one end. Intriguingly, the floor of the pit is not covered by wind-blown deposits. Questions remain about the origins of this feature.

Hi3D: A Valley West of Eberswalde Crater
This is the most prominent of several channels around the margin of the basin upstream of the Eberswalde delta. A 3D picture gives us a better look.

HiPOD 10 Aug 2022: A Clay-Rich Landslide in Tyrrhena Terra
With this image, we can assess the stratigraphic relationships between a clay-bearing unit with a strong spectral signature in CRISM that appears to correlate with extensive occurrences of a reddish bedrock that appears to span from northern Hellas to the wall-rock and uplifts of a few complex craters in Syrtis Major. Could this bedrock come from the subsurface of ejecta materials from Isidis and Hellas?
HiPOD 8 Aug 2022: Possible Layering in Reynolds Crater
Layering in this icy outlier near the Martian South Pole can be analyzed to assess its climate record, especially to test whether it has the same or different climate record compared to the South Polar Layered Deposits (SPLD). The SLPD are an ice-rich geologic unit larger than Texas in area, made of nearly pure water ice with only a small component of dust. Our camera can help us analyze all the layers in detail.
HiPOD 5 Aug 2022: Can You Hear Me Now?
Is it pareidolia, where we see features like faces and patterns where they do not really exist, if the shape really does resemble something? In this case, we’re looking at an odd-shaped impact crater that looks a great deal like an ear. And once you see it, it’s almost impossible to un-see. The crater is just over 1,800 meters across. This scene is located in Chryse Planitia in the Northern Hemisphere of Mars.
HiRISE 8K: Ridges near Reull Vallis
The objective of this observation is to determine the nature of ridges in an eroding crater. These ridges almost look as if some glacial processes had been at work here. (See link for full cutout and additional info.)

HiRISE 3D: Dune Gullies in Matara Crater
Repeat imaging of the dunes in this crater shows that material towards the top of the gullies has moved downslope, and the channel beds may have widened over time.

HiPOD 4 Aug 2022: Cones in Gusev Crater
Cinder cone-like and flow-like features at Gusev: volcanic or frost mounds? With color images and using data from CRISM, a spectrometer onboard the Mars Reconnaissance Orbiter, we can detect alteration materials if present and identify the mineralogy. Gusev is about 166 kilometers in diameter and formed approximately three to four billion years ago.It was also the landing site for the Spirit rover.
