HiPOD: A Layered Feature in a Crater in Nilosyrtis Mensae
The objective of this observation is to examine a layered feature in an impact crater. The layers may represent layers of mantle from when the climate changed and the shape may be due to the wind. The scene is also found in Context Camera data.

HiPOD: Layers in a Crater
The objective of this observation is to examine light and dark layers in an impact crater in Cydonia Mensae. Our interest is in seeing if the layer boundaries are diffuse as suggested in CTX image data. Most of the layers seem to have definite boundaries.

HiPOD: Textures of Amazonis
This observation was requested to look at some unusual surface textures in Amazonis Planitia. Some of the terrain grades into ridges that could possibly be invasive dikes or lava intruding into overlying ash. Despite the features in this image, Amazonis Planitia is one of the smoothest plains on Mars, and is located between the Tharsis and Elysium volcanic provinces, to the west of Olympus Mons.

HiPOD: Slope and Gully Monitoring
Our science goal with this target is to monitor frost in active gullies in Moni Crater. Additionally, we want to observe lineae associated with sand dunes on the eastern rim of the crater and seen to be active in the Martian winter. Moni is an approximately 5-km diameter crater in the southern mid-latitude highlands of Noachis Terra, on the inner ring of the larger Kaiser Crater.

HiRISE 3D: A Dark Spot, Revisited
Today’s HiPOD certainly warrants a look in 3D, as part of the rationale for the observation stated that stereo will be helpful for measuring the thickness of the banded terrain and layered material. (Give your eyes a few second to adjust with this one.)

HiPOD: A Great Dark Spot
This observation targets a pit partially filled with layered material and surrounded by banded terrain, as seen in Context Camera data . The relationship between the banded terrain and the layered material in the pit is unclear. HiRISE imaging may help to understand the contact between two. Stereo will be helpful for measuring the thickness of the banded terrain and layered material.

HiPOD: Defrosting Dunes
This image shows a field a sand dunes in the Martian springtime while the seasonal carbon dioxide frost is sublimating into the air. This sublimation process is not at all uniform, instead creating a pattern of dark spots.
In addition, the inter-dune areas are also striking, with bright frost persisting in the troughs of polygons. Our enhanced-color cutout is centered on a brownish-colored inter-dune area.

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.
