HiRISE (NASA)
HiRISE is a high resolution camera onboard the Mars Reconnaissance Orbiter (NASA). We take images of the surface of Mars. Based out of UArizona in Tucson.

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.

HiRISE 3D: A Crater and Its Frozen Ejecta
A post in two pics: the classic bowl-shaped crater and some of the higher-standing ejecta to the immediate north.

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.

HiRISE 3D: In Ares Vallis
Our science goal is to document stratigraphic relationships between chaos blocks and adjacent geologic units.

HiPOD: Ridges near Nilosyrtis Mensae
The objective of this observation is to determine the nature of a group of ridges. They may be inverted terrain. The surface of Nilosyrtis Mensae is classified as fretted terrain. This terrain contains cliffs, mesas, and wide flat valleys. Surface features are believed to have been caused by debris-covered glaciers.

HiRISE 3D: Possible Rhythmite-Rich Terrain
The rationale notes: "To do science with rhythmite, one must map rhythmite thicknesses which requires HiRISE stereo." Indeed!

HiPOD: Landforms in the Northeast Syrtis Major Region
With this observation, we want to study the relationship between layered sulfates in northeast Syrtis and paleotopography: was it draping or progressive submergence of land by an advancing sea? (This is also known as “onlap.”) HiRISE resolution can help to trace layers and fit bedding orientations.
HiPOD: Cliff Watchin’
Our science goal is to monitor seasonal frost on an icy scarp with known changes (falling rocks) and then get summer images to compare for other changes while well-lit and look at within-summer sublimation effects.
HiPOD: Boulders in Gully Alcoves
Gullies are often found on steep slopes. In the winter, this area is covered with a layer of carbon dioxide ice (dry ice). In the spring, when the ice warms up and transitions to gas, it dislodges material on the slope, forming a gully.
In general, this process works best on fine material, leaving behind large boulders. These boulders can be seen collected in the gully alcoves.

HiRISE 3D: Landscape Evolution in Cydonia Mensae
This large massif has slumped into an area of fretted plains and small valleys via varied geological and morphological processes, one of which perhaps tectonic.

HiPOD: Layers in a Crater Depression near Auqakuh Vallis
Also visible in a Context Camera image, the objective of this observation is to examine layers in and around a depression on a crater floor. Auqakuh Vallis is an ancient river valley about 312 kilometers in length, and is named for the word for “Mars” in Quechua (Inca).
