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.

HiRISE 8K: Light-Toned Mesas near Mawrth Vallis

Similar HiRISE images of mounds around Chryse Planitia have revealed stunning and complex meter and decameter-scale stratigraphy.

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.

HiRISE 3D: Traverse Ramp in East Coprates Chasma

“We are exploring rotorcraft mission concepts that would explore geology in Coprates Canyon, specifically low-calcium pyroxene which reflects pristine crustal material in this location.”

HiPOD 14 Sept 23: Monitoring Slopes in Gale Crater

The location of this observation is directly east of where the Curiosity rover is currently exploring. In this part of Gale Crater, there are some steep slopes with lineations we saw in previous images, so this is part of a series of observations to monitor occasionally to look for changes.

HiRISE 4K: A Smattering of Dunes

This observation was requested to gain more coverage of the eastern edge of an earlier image. The main goal is to quantify dune movement and topography over time.

HiRISE 3D: Down the Slope!

Today’s HiPOD also get the 3D treatment, with a look at part of the eastern wall of this impact crater.

HiPOD 13 Sept 23: Crater and Lava Fill in Elysium Planitia

This crater appears to have been mostly filled with lava, but there is no vent apparent within the crater: could it be invasive lava? In the eastern part there are many rafted-looking blocks that may have eroded off the crater wall. They don’t have the texture of (geologically) fresh lava. Many of them appear surrounded by moats, suggesting that the lava crust was strong enough to partially support them.

HiRISE 3D: A Source of Dunes

This image shows the head of an Abalos Undae dune field revealing possible sand source near base of Planum Boreum. This is in the north polar region of Mars.

HiPOD 12 Sept 23: Ringed Ridges in Kasei Valles

The objective of this observation is to determine the nature of ridges arranged in concentric rings. According to the requestor for this image: “I have studied many hundreds of Context Camera images and I do not think I’ve seen anything quite like this. I like to suggest images for things that are rare: this is one of them.”

HiRISE 3D: A Light-Toned Fan Deposit near Eberswalde Crater

This image to the east of Eberswalde Crater shows a nice exposure of light-toned deposits in a sedimentary fan. Context Camera data shows there are more to the west.

HiPOD 11 Sept 23: Hills in Coprates Chasma

In this image, we see two well developed cones, most likely the Martian equivalents of cinder cones, which are part of wider volcanic field in Valles Marineris. A stereo image might provide insight about their shape and size. Observations like this might provide hints about explosive conditions at the time of eruption and also why explosive volcanism occurred in this area.

HiPOD 8 Sept 23: Learning the Flow

A flow pattern along the eastern side of Aram Chaos is visible at lower elevations and is affecting the rims of multiple small impact craters. The flow of material over the rims of these craters can give insight into when this movement of material took place, and what types of material are being deposited from higher to lower regions.
