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 16 Aug 23: Icy Flows
The surface of Mars is littered with examples of glacier-like landforms. While surface ice deposits are mostly limited to the polar caps, patterns of slow, viscous flow abound in many non-polar regions of Mars.
Streamlines that appear as linear ridges in the surface soils and rocky debris are often exposed on top of infilling deposits that coat crater and valley floors.

HiPOD 15 Aug 23: From Low to High Channels
This image shows the transition from a regular channel to an inverted channel in Arabia Terra. The channel was once flowing with water that carved down into the bedrock to produce a depression.
HiPOD 14 Aug 23: Light-Toned Materials along the Floor and Walls of Ius Chasma
The light-toned deposits here are thinner and occur along both the floor and walls, as we see in this HiRISE image. Additionally, the sulfates are mixed with other minerals like clays and hydrated silica.
HiRISE 10K: Light-Toned Mounds in Ganges Chasma
This formation of light-toned mounds on the floor of Ganges Chasma have been shaped by two erosional processes: landslides and wind.

HiRISE 3D: Intersection, 3D-Style
Today’s HiPOD also gets the 3D treatment, with a closer look at the impact crater on the ridge.

HiPOD: A Crater Intersecting a Ridge
This wrinkle ridge east of Elysium Mons is a tectonic feature likely created by a thrust fault. A small crater intersects the ridge. If the crater formed before the ridge, measurements of the crater’ shape deformation can help estimate the amount of surface displacement of the fault.

HiRISE 8K: Light and Dark Features
When viewed at full HiRISE resolution, this area contains sand ripples with some consolidated, bedrock-like material poking through.

HiClip: A Crater in Scalloped Terrain
Sublimation might be responsible for creating two different landforms: scalloped depressions and expanded craters.

HiRISE 3D: Possible Channel Heading into a Crater
This could be a possible inflow from a very small catchment.

HiPOD 10 Aug 23: A New Crater in the Martian South Pole
Our science goal with this observation is to monitor the frosting and defrosting of a new, small impact crater on the South Polar layered deposits. This image can help us to understand better the thermophysical properties and changes in the crater ejecta the first few years after the crater formed. The crater is about 50 meters (164 ft) across.

HiClip: Slipping and Sliding in Echus Chaos
Echus Chaos is a region of low hills located between Lunae Planum and Echus Palus. This chaos terrain may have formed as the rocks that make up Lunae Planum slowly slid downhill into Echus Palus.

HiRISE 4K: Martian Barchans
Barchan dunes are common on both Earth and Mars. These dunes are very distinctive in shape, and are important because they can tell scientists about the environment in which they formed.

HiRISE 3D: A Vent and Channel Northeast of Arsia Mons
This small vent appears to have raised margins and sources sinuous channels. It is aligned with other fissures on the northeast flank apron of Arsia Mons.

HiPOD 9 Aug 23: Tilted in Electris
This is an interesting feature that appears to be a large anticline that is crosscut by wrinkle ridges. Our science goal is to investigate structure and timing relationships. A digital terrain model can help us with structural measurements. The Electris region of Mars contains interesting features, such as raised-relief blocks of material.

HiClip mini 4K: The Secret Life of Layers
This image shows a large outcrop of layered rock in Tithonium Chasma, a part of the Valles Marineris trough system. (This is a non-narrated clip with ambient sound.)
HiRISE 3D: A Pit or Crater near Galaxias Chaos
Context Camera data shows a strange depression here: a broad depression with a flat floor and a central elliptical depression. Is this a bullseye crater? An unusual “expanded” crater? Pit crater?

HiPOD: Spectrally Distinct Materials in Tyrrhena Terra
HiWish strikes again! This public target reads: “We are studying the relationship between specific spectral signatures and morphology (shape) associated with impact craters. This particular location has CRISM mapping signatures indicating that a closer observation and analysis may be valuable for our study.” (CRISM is a spectrometer onboard MRO.)
