HiRISE 10K: Low-Order Inverted Streams near Juventae Chasma
The raised ridges are inverted channels. It is likely that liquid water, either pure or salt water, flowed through these channels.

Tilted in Terra Cimmeria
The objective of this observation is to determine the nature of a tilted, layered deposit in a small crater. Also visible in Context Camera data, these features are relatively common in this area and some have odd shapes. They may have formed from mantle layers that have stacked up.

HiRISE 8K: Gullies in a Crater in Noachis Terra
The gullies shown in this image are similar to terrestrial gullies produced by flowing water.

HiRISE 3D: Hillslope Shapes near Holden Crater
Landscapes such as rivers, deltas and alluvial fans have been studied extensively, proving to be reliable records of Mars’ paleoclimate, while hillslopes on Mars have largely been ignored.

A Recent Cluster of Impacts
The dark spots in this enhanced-color infrared image are the recent impact craters that occurred in the Tharsis region between 2008 and 2014.
The dark halos around the resulting impact craters are a combination of the light-toned dust being cleared from the impact event and the deposition of the underlying dark toned materials as crater ejecta.

At the Confluence of Nirgal and Uzboi Valles
These layers may have been fluvial, volcanic, or aeolian (wind-blown).

HiRISE 3D: South Polar Carbon Dioxide Glacier Crevasses
These troughs are likely crevasses formed from glacial flow and their size and shape provide important information regarding the thickness and size of polar carbon dioxide.

The Southern Floor of Gale Crater
This image along the southern interior floor of Gale Crater hosts many different landforms. Light-toned, scabby, and presumably hydrated materials on the crater floor are covered by large, darker-toned dunes.
The small crater, about 2 kilometers in diameter, in the middle of the image is filled with an enigmatic deposit that appears to have flowed into the crater from the south.

HiRISE 3D: A Region outside a Crater in Phlegra Montes
Phlegra Montes is a range of gently curving mountains and ridges on Mars. It extends from the northeastern portion of the Elysium volcanic province to the northern lowlands.

Topography of the Mars Pathfinder Landing Site
Here we have the first HiRISE-produced digital terrain model of the Mars Pathfinder landing site.
Terrain here is relatively flat with only approximately 300 meters of relief, mostly due the largest crater in the scene and the hills dubbed “Twin Peaks,” first imaged by Pathfinder.

The Mars Reconnaissance Orbiter launched 19 years ago today, carrying the best camera ever sent to another planet: HiRISE!
84,595 orbits later and still going.
Well done, carbon-units. Well done.
HiRISE 3D: Geological Contacts
Our goal is to explore the contact between the possible sulfates and chaos blocks within an older crater in eastern Iani Chaos.

Beautiful Blocks of Bedrock
This enhanced color image shows the wall of the crater, which exposes layering as well as blocks of rock. There is a distinctive large block in the upper left of the crater wall, generally referred to as a “mega-block.” Several smaller light-toned blocks are also in the crater wall, possibly of the same rock type as the “mega-block.”
HiRISE 3D: Terrain Sample in Aeolis Planum
The surface in this region has been heavily eroded by wind action.

Bedrock Exposures in Nirgal Vallis
This observation covers two tributaries and a main channel with light-toned bedrock throughout the scene. HiRISE provides a more detailed look at the stratigraphy. Nirgal Vallis is a long river channel about 610 kilometers long, and is named after Nergal, the Babylonian god of war and counterpart to the Roman god of war Mars.

Too hot outside and need something to do inside? Our August image catalog update awaits:
Ice Blocks Sliding Down Dunes
Russell Crater hosts a large dune field. In the spring, carbon dioxide ice on the gently sloping side of the dune sublimates (evaporates) first, leaving a warm sandy slope.
At the crest of the dune alcoves harbor ice longer, which then breaks off in large chunks and slides down, forming linear gullies. Sometimes the sliding ice block leaves a cloud of dust, as we see in this image.

HiRISE 3D: Crater Rim Deposits near Planned ExoMars Landing Site in Oxia Planum
This is part of our August image catalog update (dated 6 Aug). https://www.uahirise.org/anaglyph/
Spiders in Manhattan
After ice sublimates and erupts, thin debris falls to the surface of the ice in dark fan-shaped deposits, oriented by the wind blowing at the time of the eruption. The surface below the ice is eroded into channels known as araneiform terrain, colloquially called “spiders.”
