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.

HiRISE 3D: Streamlined Features in Athabasca Valles

The rationale for this observation was elegantly simple: to extend coverage of spectacular landscape.

HiPOD: A Sedimentary Fan in Southeast Gale Crater

This image covers a fan of sedimentary rock on the southeast crater floor. Ridges on the fan surface may be composed of coarse-grained sediment deposited in ancient streams. More recent wind erosion of the surrounding finer sediments could have left these channel deposits elevated in “inverted relief.” A closeup shows some of these ridges, as well as light-toned layers of sediment.

HiRISE 3D: A Recent Impact near Hebrus Valles

This impact occurred inside a double quasi-concentric circular graben structure. These features have been interpreted as the result of compaction of soft sediments filling a large crater basin.

HiPOD: Muddy Mounds

Mud volcanoes form as gas and liquid-rich sediment interacts underground. Over time, this slurry of mud is brought to the surface and forms a rounded mound. Scientists are interested in studying mud volcanoes on Mars because the material forming the mound has the potential to be organic in nature and would give insight into possible microbial life below the surface.

HiPOD: A Three-in-One in Meridiani Planum

With this observation, we were able to get three targets of interest in a single image: good candidates for recurring slope lineae on the slopes, small gullies and the entire impact crater itself. Meridiani straddles the Martian equator and is one of the most investigated regions of Mars.

A Fissure Vent East of Olympus Mons

This fissure is one of many in the volcanic plains east of Olympus Mons. The purpose of the image is to resolve any erupted material and overlap the adjacent HiRISE stereo pair to expand DTM coverage.

HiPOD: Out of Eberswalde

This observation shows us the most prominent of several channels around the margin of the basin upstream of the Eberswalde delta. With a closer look and stereo pair at some point, we can study the channel in better detail and determine valley dimensions.
