HiPOD: Seasonal Flows in the Central Mountains of Hale Crater
The recurring slope lineae (RSL) in Hale have an unusually “reddish” color compared to most RSL, perhaps due to oxidized iron compounds, like rust. Since HiRISE color is shifted to infra-red wavelengths, they are actually especially bright the near-infrared just beyond the range of human vision.
HiPOD: Layering in Spallanzani Crater
In this image, we can see quite a spectacular layering pattern inside an impact crater called Spallanzani. Seeing layering is always exciting to geologists because it implies that the region has experienced multiple climatic conditions or geologic processes through time.
HiRISE 3D: Dunes in 3D
These dunes are also visible in MOC images.

HiPOD: Yardangs in Arsinoes Chaos
The slightly curving, sublinear bright terrain is composed of yardangs. Yardangs are portions of rock that have been sand blasted into long, skinny ridges by saltating (or bouncing) sand particles blowing in the wind.
HiPOD: A Polar Smile
This image represents one of many monitoring sites at the South Pole residual cap (SPRC). Images are taken throughout the Martian year to document changes in carbon dioxide ice coverage.
This image shows a popular spot where one of the features resembles a smiley face that is approximately 500 meters across. If you smile at Mars, sometimes it smiles back.

HiRISE 3D: Crater Ejecta Crosscut by Channels in Aeolis Dorsa
One of our goals is to seek confirmation of multiple episodes of flow: are the channels filled by fluvial materials, debris flows, or something else?

HiPOD: Valleys in Deltoton Sinus
The objective of this observation is to examine valleys on the wall of an old crater. These valleys are wide, and then they get narrow and become very steep. There may have been waterfalls here. The scene can be found in Context Camera data. The name means “bay of the triangle” and its location makes triangle with Iapygia and Oenotria.

HiRISE 3D: Ridges on the Floor of Shalbatana Vallis
These curved ridges are real, and they’re spectacular!

HiPOD: In an Unnamed Crater
Also available in Context Camera data, we acquired this observation to examine gullies in a small, southern mid-latitude crater. Images like this one will help us increase our inventory of Martian gullies. This scene is located in Terra Sirenum, in the Southern Hemisphere of Mars.

HiRISE 3D: Layered Late-Stage Fan in Gale Crater
Our rationale is to search for boulders for comparison to Gediz Vallis ridge currently adjacent to the Curiosity rover.

HiPOD: This is Not Hadrian’s Wall
This observation shows us a spectacular long-running ridge located to the north of Vernal Crater. These ridges may be large, mineralized fracture zones. This image was requested to investigate further and take a look at the structure within the ridge, especially with a digital terrain model to help. (Black and white cutout is less than 5 km across; enhanced color is less than 1 km across.)

HiRISE 3D: At the North Pole
This observation was requested to re-image for potentially active tectonic activity that we can compare to a previous image in 2008.

HiPOD: Layers in a Low Latitude Crater
The objective of this observation is to examine thin layers in a small crater on the floor of a larger crater. These thin, regular layers may be evidence that a lake once sat in the larger crater. This is scene is also visible in a Context Camera image.

HiRISE 3D: Mounds in Oxia Colles
This landform shows distinctive layering in CTX, and is similar to other buttes to the far north east which have been observed to have Mawrth-like stratigraphy.

HiPOD: An Inverted Channel West of Idaeus Fossae
This observation shows a multithreaded, inverted fluvial channel located to the west of Idaeus Fossae. The formation may date back to the mid-Noachian epoch, billions of years ago. There is also evidence for lateral channel migration and is possibly associated with fan deposits in an impact crater to the east.

HiRISE 3D: A Southern Canyon Wall in East Coprates Chasma
The walls here potentially expose pristine crustal material. This is an area of interest that could be accessed and is within a potential future rotorcraft mission traverse.

HiPOD: Fluvial Landforms in Granicus Valles
In this image, large, streamlined features and grooves have been carved by enormous water volumes into the floor of Granicus and point to the direction of flow towards the northwest. The floods of Granicus Valles are thought to have formed later in Mars history during the Amazonian epoch, several billion years ago.

HiRISE 3D: He’s Baaaaack!
Yes, it’s the (in)famous formation first imaged in low-resolution by the Viking probe back in 1976. We’ve imaged it before, but now you can view it in 3D glory!

HiPOD: Curving Ridges in Aeolis Planum
Multiple processes, which may have occurred billions of years apart, are reflected in this HiRISE image of Aeolis Planum.
Cutting across the scene are curvilinear ridges. These likely represent ancient, meandering river channels that flowed across the surface and buried themselves over time. The channels have subsequently been exposed to the surface by the wind, forming the cross-cutting ridges.
