HiPOD: Dunes of an Unnamed Crater
This scene is located within an unnamed impact crater to the northwest of the larger Antoniadi Crater in the Northern Hemisphere of Mars. We obtained this image to observe possible changes in dune position, and for more coverage of star dunes, which are dunes with arms radiating from a central peak. Star dunes are more common on Mars than on Earth.

HiPOD: Dunes on the Floor of Huggins Crater
Dunes are particularly suited to comprehensive planetary studies because they are abundant over a wide range of elevations and terrain types. A global scale study of Martian dunes serves a dual purpose in furthering understanding of both climatic and sedimentary processes, two fundamental topics currently driving Martian science.

HiPOD: The Hills in Ganges Chasma
Ganges Chasma is in the northeast portion of Valles Marineris, and opens into outflow channels that flowed to the north.
Scattered hills on the canyon floor may be remnants of chaos terrain that formed from collapse of the canyon. Some of the bedrock has diverse colors as we see in the enhanced-color cutout.

HiRISE 3D: Light-Toned Layered Deposits Exposed along Coprates Chasma Floor
Context Camera data shows exposure of light-toned layered deposits at this location. Our resolution can take a closer look at the details in the layering.

Channels near Huygens Crater
The objective of this observation is to examine channels on the outside of an impact crater. They lead away from the rim, and perhaps they were formed by the heat of the impact melting ground ice. There are many additional channels located in this general area, and much ice may have been present in the ground. This scene is also covered in Context Camera data.

HiRISE 3D: Dune Monitoring in a Northern Mid-Latitude Crater
This was part of a seasonal series to track changes over time. This image had less frost than previous observations.

Megaripple Stripes on Mars
Among the undulating topography of this dune field in Rabe Crater, one notable feature is the presence of distinct megaripple stripes. Intermediate in size relative to larger dunes and smaller ripples, these megaripples gather in parallel rows, their formation guided by wind patterns and the distribution of grain sizes.

HiRISE 3D: Volcanoes and Collapses
This image of Hephaestus Fossae shows a volcanic area where collapses like this happen. Chains of large elliptical pits mark the path that underground molten rock took.

Hematite in Capri Chasma
The Thermal Emission Spectrometer on the Mars Global Surveyor detected hematite along the chasma floor and edges of these mesas in Capi Chasma. Hematite on Earth is typically formed in aqueous environments or by aqueous alteration, so its presence warranted investigation by the two Mars Exploration Rovers, Spirit and Opportunity, that found a significant amount of the mineral.

The Floor of Mawrth Vallis
CRISM data shows a localized, unique spectral phase consistent with poly-hydrated sulfate or zeolite here on the Mawrth Vallis channel floor, with implications for the regional history. This target provides both color coverage and stereo over the outcrop. We can also look for textual differences between new hydrated mineral and adjacent clays.

Noachian Bedrock Diversity
In an adjacent image we acquired in 2008, there was terrific color and texture diversity, so this observation was acquired to extend coverage. There are clays mixed with unaltered mafics in this area as well. “Noachian” refers to the early geologic period after Mars formed, 3 to 4 billion years ago.

HiPOD: Colorful Impact
Our enhanced image reveals colors ranging from red to green to blue. These are infra-red shifted colors (infrared-red-blue) so it’s different than what we would see with our eyes.
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.
