HiPOD: Gullies in the Depths of Hellas
Gullies are commonly found in the Martian mid-latitudes, particularly in the Southern Hemisphere. However, they are rare in the deepest parts of the massive Hellas impact basin.
For this image, HiRISE targeted a relatively fresh crater where previous images from the MRO Context Camera appeared to show gullies. This high-resolution look confirms their presence.
HiPOD: Sediment Ponds in Tithonium Chasma
This survey of the canyon floor of Tithonium Chasma in Valles Marineris reveals terrain of two distinct ages. The slopes and hilltops here are made up of rough rocky outcrop that was sculpted by impact craters of all sizes. In contrast, the valley floors are filled with light toned, smooth materials with far fewer large craters.

HiRISE 3D: Topographic Interactions in Athabasca Valles
The request for this image was to retarget for an observation centered on the interactions between lava, topography, and a fissure.

HiPOD: Hydrated Sulfates in Melas Chasma
This image was acquired to get more information about a site where the CRISM instrument detected hydrated sulfates. The bright materials are likely to be sediments rich in the hydrated sulfates, and this image shows that most of the material is covered by a thin deposit of dark material, perhaps sand.
HiPOD: A Channel in Huygens
The objective of this observation is to examine small, eroded channels. In this spot are many branched channels that have dark material on their floors. This image is located on what is left of the eroded southwest crater rim of Huygens, which is 467 km (290 mi) in diameter. The scene is also available in Context Camera data.

HiRISE 3D: Ridges West of Vernal Crater
These may be large mineralized fracture zones, so our image will help us to investigate further.

HiPOD: A Ridge in the Low Southern Latitudes
The objective of this observation is to determine the nature of a long straight ridge. At a point the ridge seems to disappear at the edge of an old crater and then reappear after a pause. It may be a dike. Along its length it has narrow portions and wide portions. The scene is also available in Context Camera data.

HiPOD: The Dunes of Change
The Mars Orbiter Camera imaged these dunes in 2000, so now we can learn what a multi-decade dune movement average is by taking a new observation to create a MOC-HiRISE temporal pair. With MOC providing a long baseline to newer HiRISE images, we can build up global averages of the effects of wind on the environment. Two decades is long enough that the dunes will have moved noticeably between MOC and HiRISE.

HiPOD: Fluvial Erosion in Harmakhis Vallis
This observation was requested by a Mars class to examine fluvial processes in one of the large channels leading into Harmakhis Vallis. The requested image is in a corner pointing opposite of the flow, possibly creating an eddy/turbulent area. The goal is to get a high resolution look for shoreline markings and erosion effects. Harmakhis Vallis probably formed by a combination of surface collapse and flowing water.
HiRISE 3D: Channels in Hebrus Valles
The objective of this observation is to examine channels and streamlined features. The main channels seem to go into a short trough.

HiPOD: A Candidate Recent Impact Site
Why do we initially say “candidate”? Before HiRISE acquires an image, the Context Camera on MRO might observe something that could be an impact, but their resolution is not like ours. In one of their images, there was a large diffuse dark blast zone that was not present in an earlier observation, so that team asked HiRISE to acquire a picture to confirm if this is an impact crater.

HiPOD: Layering in Arabia Terra
The objective of this observation is to search for layering in Arabia. In Context Camera data, the layering shows up in buttes, ridges, and the edges of mesas. Our image may be able to see many more of these layers. This image will also help us to determine the horizonatal extent of layering in the region.

HiRISE 3D: Ridges in Huygens Crater
We acquired this image to investigate the timing relationship between the wrinkle ridges and the quasi-circular mesas.

HiPOD: Channel, Fan, Crater
The objective of this observation is to examine a channel on a crater wall, where a fan has formed at the base. Images like this, also found in Context Camera data, may help us better understand how craters are degraded. This particular crater is one of many located to the northwest of the massive Hellas impact basin.

HiRISE 3D: A Partly Filled Impact Crater near Nicholson Crater
This anaglyph shows an infilled and possibly exhumed crater. HiRISE resolution can examine the shape of the crater fill and any wall layering.

HiPOD: A Circular Landform within an Impact Crater
This circular formation appears to have the land around it sloping to its edge. The formation then looks to rise out of the ground with various others different formations around it. There also what appears to be a small crater on the top. When viewing this area using infrared background, the land formation has several markings on one side more than the other.

HiPOD: A Patchy Outcrop of Light-Toned Materials
This observation targets a small region of patchy light-toned materials visible in Context Camera images. These outcrops are small, precluding geomorphological analysis and assignment of a stratigraphic position relative to the surrounding materials. The shape of this material closely resembles sinuous, light-toned outcrops elsewhere in Terra Cimmeria.

HiPOD: Bedrock Exposures in Nirgal Vallis
This observation covers two tributaries and the main channel of Nirgal Vallis. The channel is approximately 610 kilometers long and is named after Nergal, the Babylonian god of war and counterpart to the Roman god of war, Mars. Mars Orbiter Camera image show light-toned bedrock; our high resolution picture can gives us a better view of the channel form and bedrock stratigraphy.
