HiRISE 10K: Ice in a Chlorite-Bearing Cliff in Northwest Hellas

A south-facing escarpment in the northwest Hellas region that was targeted for phyllosilicates (this includes clay minerals) shows instances of bluish rock in this enhanced color image.

HiRISE 3D: The West Rim of Well-Preserved Impact Crater

This crater rim is nice and sharp-looking, despite that it might have formed an extremely long time ago. While not pictured in this cutout, the ejecta pattern is also still visible.

HiPOD 24 Feb 2022: Marvelous Mounds

Rising above the crater pockmarked plain of Chryse Planitia, the objective of this observation is to examine mounds that have ridges and are located atop pedestals. The scene is also pictured in a Context Camera image.

HiRISE 8K: Active Slope Flows on the Central Hills of Hale Crater

HiRISE has been monitoring steep slopes on Mars because some of them reveal active processes. In some cases, there are many seasonal flows on warm slopes, suggesting some role for water in their activity. (Click the link for the full cutout and additional information.)

HiRISE 3D: A Glance at Hebes Chasma

Looking at sedimentary and layering processes is the goal of this observation. Well, perhaps “marveling” is the better word.

HiPOD 23 Feb 2022: On Floor of Coprates Chasma

In previous images, this impact crater on the floor of Coprates Chasma has some really promising candidate recurring slope lineae (RSL) on north-facing slopes. Could they be active in the northern summer? RSL still remain a topic of investigation to determine their nature and the processes that create them. Coprates Chasma is part of the Valles Marineris canyon system.

HiRISE 4K: Valleys in Tyrrhena Terra

Enigmatic, shallowly incised valleys are found in some mid- to low-latitude regions on Mars. These valleys are very different in appearance compared to the very old, large, and well-developed valley networks on Mars.

HiRISE 3D: A Crater in Hydraotes Chaos

This small crater happens to be the lowest elevation (less than 5600 meters) in the tropical zone of Mars, so evidence of ancient water activity could be there.

HiPOD 22 Feb 2022: A Flow Intersection at Cerberus Fossae

At this location, a portion of the Cerberus Fossae seems to intersect with the edge of a lava flow or other feature nearly perpendicular to the fossae. This could be a good location to investigate stratigraphic relationships and other aspects of the relationship of the fossae to the surrounding terrain.

HiRISE 3D: Rocky Outcrops to the Northwest of the Elysium Region

There is some unusually high thermal inertia in this region, which is the amount of heat retained during the night. Why might this be the case?

HiPOD 21 Feb 2022: Dunes in Capen

This observation gives us a nice view of dunes on the floor of Capen Crater, located in Terra Sabea. However, our primary interest is with the dark-toned layered material the dunes are mostly covering up. Capen is a 70-kilometer impact crater named for astronomer Charles Capen, an apprentice to Clyde Tombaugh, the discoverer of Pluto.

HiRISE 3D: An Inner Channel in Kasei Valles

This observation is one of a couple images remaining that are needed to complete mosaic coverage of this nice inner channel and the covering lava.

HiPOD 18 Feb 2022: Dunes with Erosion-Resistant Layers

Dunes with exposed bright bedding have been proposed to contain evaporites (minerals found in the sedimentary deposit of soluble salts that results from the evaporation of water). In this observation, there are dunes with erosion-resistant and ripple-covered bright layers that could be cemented materials.

Or, perhaps, Númenor. This landform shares many characteristics with the two landforms to the north: multiple tiers, bright-toned layering and fracturing.

This image is located on the southeastern flank of a volcano on Mars called Arsia Mons. On the eastern side of the image, the lobate margin of an old lava flow is visible among brighter tones.

HiClip: Boundary Boulders (narrated by Tre Gibbs)

HiPOD 16 Feb 2022: Boundary Boulders

On this part of Mars there is an extensive surface brightness (albedo) boundary. One hypothesis is that this boundary marks a shoreline, from a time long ago when liquid water could have been stable on the surface of Mars.

With the resolution of HiRISE we can see that the reason one side of the boundary is darker than the other is due to the many boulders strewn across the darker side.
