HiRISE 3D: Possible Exposure of Polar Layered Deposits
The goal of this observation is to determine topography in an area not observed by MOLA (Mars Orbiter Laser Altimeter).

To Great Depths
This image from eastern Hellas Planitia shows some of the unusual features on the basin floor. These relatively flat-lying “cells” appear to have concentric layers or bands, similar to a honeycomb. This “honeycomb” terrain exists elsewhere in Hellas, but the geologic process responsible for creating these features remains unresolved.

HiRISE 3D: A Cliff in Hellas Planitia with Linear Gullies
This area contains a significant scarp. Other observations along this scarp show highly visible gullies. CTX images show darker colored ground in this area.

An Inverted Channel in Aniak Crater
'The objective of this observation, also available in Context Camera data, is to examine a valley that turns into a ridge in the southeastern part of Aniak Crater. This is probably an example of an inverted channel, so the material that formed it was more resistant to erosion than the surrounding terrain.

HiRISE 3D: A Possible ExoMars Landing Site in Oxia Planum
This image again highlights HiRISE’s crucial role in selecting potential landing sites, not only due to high resolution, but for 3D images to help assess risk.

Small Channels near a Central Pit in Terra Cimmeria
There are small channels visible in Context Camera data that are of interest at HiRISE resolution. The host crater is (relatively) fresh and thus may be geologically young; the channels incised on both its northern interior rim and floor may be candidates for impact induced hydrothermal activity.

HiRISE 3D: An Inverted Channel in Arabia Terra
This observation features a spectacular inverted channel in Arabia Terra. Maybe a channel belt?

Well-Exposed Layers near the Rosalind Franklin Landing Site
The Rosalind Franklin rover from the European Space Agency is expected to arrive at Mars in a future year, to study ancient layered bedrock in the Oxia Palus region about 80 kilometers to the northeast of this image location.
This observation is part of a stereo pair of a 1.5 km-wide crater with excellent exposures of the bedrock layers, that will help reconstruct the stratigraphy in the region.
HiRISE 3D: A Crater with Steep Slopes
There might also be gullies here, in a region where gullies are not typically present due to elevation.

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 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.
