Hot Mineral Veins in Mounds in Ariadnes Colles
The Ariadnes Colles region is a large basin in the southern highlands covered by mounds. The mounds expose bedrock riddled with light-toned veins of mineral-filled fractures. This suggests hydrothermal alteration: hot water carried and deposited minerals. On Earth, heat-loving microbes thrive in such settings.

Clinoforms in Melas Chasma
The layered deposits in Melas Basin may have been deposited during the growth of a delta complex. This depositional sequence likely represents a period where materials were being deposited on the floor of a lake or running river.

HiRISE 10K: Layered Sediments in Tithonium Chasma
This image shows a large outcrop of layered rock in Tithonium Chasma, a part of the Valles Marineris trough system.

HiRISE 3D: Gullies on Wall of Matara Crater
This image was requested to study even the tiniest of streamlines for drainage profiles for one of the larger gullies in this locale.

Layered Mantling Deposits in the Northern Mid-Latitudes
These deposits accumulate over cycles in layers, and here in the southern mid-latitudes, where the deposits have mostly eroded away due to warmer temperatures, small patches of the remnant layered deposits can still be observed.

NASA’s Perseverance Rover Scientists Find Intriguing Mars Rock – The six-wheeled geologist found a fascinating rock that has some indications it may have hosted microbial life billions of years ago, but further research is needed.
HiRISE 8K: Cerberus Fossae Fissures
This image shows several parallel segments of the Cerberus Fossae. This is a system of fissures formed by extension and stretching of the near-surface of Mars.

HiRISE 3D: A Well-Preserved Impact Crater with Extensive Secondaries
This re-image was requested to confirm as to whether or not the crater here is responsible for all the secondaries observed on the steep slopes directly to the west of the impact site.

Muddy Ejecta Flow
The ejecta spraying out of the new crater landed back on the ground and then continued to flow away from the new crater, and the smaller crater was in the way of that muddy flow. You can see where much of the muddy material flowed around the crater’s uplifted rim and forms a squiggly ridge, but you can also see where the mud flow slid over the rim and ponded down in the bottom of the crater.

HiRISE 4K: Valles Marineris Wall Rock
Since Valles Marineris cuts into the side of the Tharsis volcanic rise, it is likely that these layers are lava flows.

HiRISE 3D: A Channel Enters a Crater
At least it wasn’t entering a bar. There is some faulting of icy crater fill as well in this image.

Colorful Bedrock Exposed in a Landslide Scarp
The steep walls of Valles Marineris sometimes fail, creating giant landslides. This provides a clean exposure of the underlying bedrock.
This image of the north wall of Ganges Chasma reveals bedrock with diverse colors and textures, representing different geologic units.

HiRISE 3D: Possible Spatter Cones East of Arsia Mons
A “spatter cone” is a miniature volcanic cone on a crater floor or lava flow from which lava is ejected in drops or gobs.

The Coolest Landscape on Mars (or Earth)
Many Martian landscapes contain features that are familiar to ones we find on Earth, like river valleys, cliffs, glaciers and volcanos.
However, Mars has an exotic side too, with landscapes that are alien to Earthlings. This image shows one of these exotic locales at the South Pole.

How Gas Carves Channels
The ground likely started as polygonal patterned ground (common in water-ice-rich surfaces), and then escaping gas widened the channels. Fans of dark material are bits of the surface carried onto the top of the seasonal ice layer and deposited in a direction determined by local winds.

HiPOD: Bang and Whoosh!
This HiRISE image captures a new, dated (within about a decade) impact crater that triggered a slope streak. When the meteoroid hit the surface and exploded to make the crater, it also destabilized the slope and initiated this avalanche.
Slope streaks are created when dry dust avalanches leave behind dark swaths on dusty Martian hills.

HiPOD: Martian Meanders and Scroll-Bars
Channels become inverted when the sediments filling them become more resistant to erosion than the surrounding material. Here, the most likely process leading to hardening of the channel material is chemical cementation by precipitation of minerals. Once the surrounding material erodes, the channel is left standing as a ridge.
HiPOD: It Shrinks! It Cracks!
Here, we have a crater that lies close to Elysium, a major volcanic system on Mars. The whole region surrounding the crater was at some point covered by lava from the volcano creating vast lava plains, and in the process, flooding impact craters in their way.
HiPOD: Dune Transition in the High Southern Latitudes
This image shows a moderate sized dune field (-72 degrees latitude) that displays most of these morphologic features and a noticeable absence of dune crests. This transition is likely related to polar processes, ground ice, and changes in regional climate relative to the rest of the planet.
HiRISE 8K: The Floor of Kasei Valles
This HiRISE image shows a wonderfully complex surface on the floor of this ancient flood-carved canyon.
