HiPOD 2 May 2023: Complicated Lava Cooling
In this lava, a crust of rubble forms as the lava partially cools but then tears up its own cover. Eventually, the rubble can form plates that can be rafted apart as the lava cools further, producing textures like those visible on terrestrial lava lakes that have cooled.
HiRISE 3D: The Distal Rampart of Toconao Crater
Toconao Crater has some of the best preserved distal ramparts of any crater on ridged plains materials. This is one of several images that will enable us to more fully study the morphology of these ramparts, thereby building our knowledge of the ejecta emplacement process.

HiRISE 10K: Flow Features in Nereidum Montes
There was not much by of a description for this observation, but this incredible viscous flow lobe speak for itself.

HiPOD 1 May 2023: Glacier-like Features on Mars
Glacier-like features like this indicate that ice accumulated here in the past, which does not happen in today’s climate. It’s somewhat of a mystery why these features have flowed so much when they are so thin, the ice is so cold, and Martian gravity is so low.
HiRISE 3D: A Landslide in a Southern Mid-Latitude Crater
The objective of this observation is to examine a landslide in a crater. It has a nice, symmetrical shape. Pictures like this will help us understand mass movements on Mars.

HiPOD 28 Apr 2023: A Circular Mesa on the Red Planet
Can we see layering in the scarps of this mesa? The larger circle here formed as a scarp retreated away from a previous crater’s raised rim. The terrain has a lot of variety and elements, including dark, spotty surfaces (big boulders?). Was this below sea level in some hypothetical northern plains-covering ocean? Is there any evidence for sediment in that ocean basin here?

HiRISE 8K: Dune Gullies at Proctor Crater
This image was a public request from our HiWish program. The rationale was to match the footprint of a previous image from 2016 in order to identify any changes since then.

HiRISE 3D: Rocky Terrain near Nili Fossae
Along with the awesome mineral diversity, there are also polygonal networks of erosionally exposed ridges here.

HiPOD 27 Apr 2023: Megabreccia in Northeast Syrtis
The region of interest contains megabreccia that may be a breccia dike. It is important to determine this in order to understand the impact dynamics that created the Isidis basin and the megabreccia blocks exposed in the northeast Syrtis region. This image was requested for a stereo pair to provide 3D context to learn about the exact nature of this megabreccia exposure.

HiRISE 4K: Layered Bedrock in the Northeast Hellas Region
This sample of the terrain in the northeast Hellas region shows us some very spectacular examples of exposed, light-toned bedrock.
HiRISE 3D: Atop the Dune
There appears to be a small impact crater on the top of this dune, which itself has an interesting pyramid shape. The darker material is still visible after the impact.

HiPOD 26 Apr 2023: A Flow-Like Feature within Chryse Planitia
This image covers a flow-like feature that is hypothesized to be the result of subsurface sediment mobilization. With it, we can investigate details about the associated mud movement over the Martian surface. The flow is showing an interesting shape that might be evidence of the former presence of an icy-muddy crust.

HiPOD 25 Apr 2023: About a Landform
At the southeastern edge of a huge impact crater, Context Camera data show a candidate delta formation, which is interesting because other CTX observations and an earlier HiRISE picture show channels and light-toned fans feeding a playa deposit at a lower elevation. Could there have been two different lake levels within this crater?

HiRISE 3D: A Sedimentary Fan in a Crater in Terra Cimmeria
There is a sedimentary fan within this crater that appears to have preserved distributary channels.
HiPOD 24 Apr 2023: A Degraded Crater in the Utopia Region
Eventually, time is a drag on everything. Context Camera data show that this impact crater is fresh enough to still have bright rays and ejecta, yet is heavily and strangely modified. In addition to examining the rays in detail, we also want to take a look at any boulders and polygons.

HiPOD 21 Apr 2023: Possible Sulfate-Rich Terrain
One interpretation of this area is that Valles Marineris sulfate layers once filled the canyons. Another proposes that sulfate deposits grew as domes. A prediction is that layer orientations should be aligned with, though gentler than, modern surface slopes.
HiPOD 20 Apr 2023: A Chaos-Like Valley
This locale contains fluvial-like channels in the upland portion which transitions to a broken-up, blocky terrain occupying an amphitheatre-shaped valley. This valley is reminiscent of chaos terrain and may indicate collapse due ice table melting. This location may hold clues regarding the relationships between these features and have broader implications for the ice deposit formation throughout the region.
