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.

HiRISE 3D: Raised in Athabasca
This observation shows part of a high-standing mesa in an ancient lava field.

HiPOD: Dune Avalanche Slopes
These dunes have exhibited recurring slope lineae (RSL)-like streaks in a couple of previous images, but they do not seem to have been significant in 2013, when we obtained a full monitoring series. With this observation, we can keep monitoring to understand this activity, which may help test the RSL-granular flow model for the streaks.

HiRISE 8K: Bright Streaks and Dark Fans
The conditions must be just right for the bright frost to condense.

HiRISE 3D: Like a Big Pizza Pie…
Only this one is seen from the Mars sky! This image shows a pie-like feature which is hypothesized to be the result of subsurface sediment mobilization.

HiPOD: Terrain in Hebes Chasma
Hebes Chasma is an isolated depression to the north of Valles Marineris, with no outflow channels. Some material on the walls of the chasma is different from the central mesa. We obtained this observation to investigate a possible landslide within the stratified sediments from one of the chasma’s walls.

HiRISE 4K: Isolated Araneiform Topography
Have you ever found that to describe something you had to go to the dictionary and search for just the right word?

HiRISE 3D: Layered Ejecta
This double pic shows an impact crater with its ejecta blanket that has withstood erosion to be elevated above the surrounding terrain.

HiPOD: A Clay-Rich Mound in an Eroded Plateau
These mounds contain bright-toned material which have been found to be clay-bearing with data from the CRISM instrument on MRO. This particular example contains both aluminum and iron/magnesium bearing clays. These regions of bright-toned material are layered down to the meter scale and are heavily fractured, reminiscent of the clay-bearing deposits at Mawrth Vallis.

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.
