HiClip mini 4K: Ridges of Times Past
Also visible in Context Camera data, objective of this observation is to determine the nature of a field of ridges near Apollinaris Sulci. (This is a non-narrated clip with ambient sound.)
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.

HiRISE 3D: Nili Patera Dunes
We acquired this observation to provide further high resolution images of the Nili Patera dune field.

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.

HiRISE 3D: Light-Toned Exposures near Voeykov Crater
Our goal here is a comparison with CaSSIS DTM and stratigraphy. CaSSIS also identified peculiar color variation here.

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.

HiRISE 3D: Terracing Inside and Outside a Degraded Crater Rim
This image shows multiple bands on the inside and outside of a crater rim that may be terraces. Are they paired topographically?

HiRISE 3D: A Buffet of Secondary Craters
This observation is part of a study that aims to characterize how secondary crater shape depends on distance from source craters and hence impact velocity.

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.
HiPOD: Seasonal Flows in the Central Mountains of Hale Crater
The recurring slope lineae (RSL) in Hale have an unusually “reddish” color compared to most RSL, perhaps due to oxidized iron compounds, like rust. Since HiRISE color is shifted to infra-red wavelengths, they are actually especially bright the near-infrared just beyond the range of human vision.
HiPOD: Layering in Spallanzani Crater
In this image, we can see quite a spectacular layering pattern inside an impact crater called Spallanzani. Seeing layering is always exciting to geologists because it implies that the region has experienced multiple climatic conditions or geologic processes through time.
