HiPOD 27 Sept 23: An Extra-Crater Sinuous Ridge

Identifying these types of fluvial ridges outside of craters is critical for reconstructing ancient sedimentary basins, and channel deposits in basins are one of the key deposits used to constrain ancient climate, water discharge, and base-level changes. This is a previously unidentified sinuous ridge from a recent global survey of such features.

HiRISE 3D: The Lower Reaches of Shalbatana Vallis

This anaglyph shows fluvial shapes at the terminal zone of an outflow channel. Meter-scale shapes may be indicative of flow.

HiPOD 26 Sept 23: Radial Ridges on a Crater Floor

The objective of this observation is to determine the nature of a group of short radial ridges on an old crater floor. These may be inverted channels from previous glaciers in the crater. The scene can be found in Context Camera data.

HiPOD 25 Sept 23: A Fan in a Low Latitude Crater

The objective of this observation is to examine a possible fan along the wall of an impact crater. Ridges coming from a valley on the wall may be inverted terrain. The crater floor contains a depression that displays layers; hence, there may have been a lake in the crater.

HiPOD 23 Sept 23: A Layered Mound in Juventae Chasma

The light-toned mounds, like this one in Juventae Chasma, generally contain sulfates, which are salts of sulfuric acid that form when water is evaporating.

The darker material that we see is collecting near the base of the light-toned mound, and likely represents wind-blown debris.

HiRISE 3D: Deposits in Melas Chasma

This image was acquired as part of coverage for a candidate landing site for the Mars 2020 mission. There are possible interior layered deposits here.

HiPOD 22 Sept 23: A Candidate Landing Site in Hypanis Valles

This image w as acquired as part of a candidate landing site for the Mars 2020 mission to examine an exhumed, fluvial deltaic system in Xanthe Terra. The CRISM instrument on MRO was also requested for coverage to look at any correlation between the mineralogy and the deltaic deposits.

HiRISE 3D: Possible Sulfates in the Northeast Syrtis Major Region

In addition to the possible sulfates here, this area is of potential interest as a go-to destination for a future mission.

HiPOD 21 Sept 23: About a Pedestal Crater

This observation shows us a possible, rare example of an expanded primary crater, and other expanded crater clusters (likely secondaries). There seem to be few recent expanded craters, which is a key clue to the history of excess ice.

HiPOD 20 Sept 23: Channel Crossing

This observation targets a channel crossing a heavily eroded wrinkle ridge. On the south side of the wrinkle ridge, a dark-toned channel is inset within a light-toned material. The light-toned material may be related to the channel, such as altered primary minerals related to the presence of groundwater. This observation will evaluate the relationship between these two materials.

HiPOD 19 Sept 23: Massifs on Layered Bedrock in Acidalia Planitia

This large platform in Acidalia Planitia contains a group of massifs. These massifs generally appear to be sitting on layered bedrock that may have been islands at one time. Understanding their formation will do much for helping to understand the wetter history of Mars as well as clues to the origins of these various and curiously shaped, tall, singular and grouped massifs.

HiRISE 3D: The Floor of Uzboi Vallis South of Nirgal Vallis

This shows the possible edge of a Nirgal Vallis deposit. The science goal is to look for evidence of spillway from Hale Crater flows into Uzboi.

HiPOD 18 Sept 23: Streamlined in Coracis Fossae

Also visible in Context Camera data, the objective of this observation is to examine streamlined forms in a narrow channel. The width of the channel is fairly constant and curves at points. Linear features in this region include both tectonic graben and fluvial channels.

HiPOD 16 Sept 23: A View of the Painted Desert near Mawrth Vallis

The clay-rich terrain surrounding Mawrth Vallis is one of the most scenic regions of Mars, a future interplanetary park. Here, we cut a long, oblique view into strips to see the full color coverage in more compact form.

HiPOD 15 Sept 23: Ridges in Nereidum Montes

We acquired this image to take a detailed look at rectilinear ridges near ice-rich material in Nereidum Montes. They could be ancient moraines. A moraine is material left behind by a moving glacier. This material is usually soil and rock.
