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.

HiRISE 8K: Clay-Rich Terrain along a Fracture

This image was requested to gain HiRISE coverage over existing high-resolution CRISM data.

HiRISE 3D: Cliff Watching

The goal of this observation is to monitor the ice exposure for any changes from previous images.

HiPOD 7 Sept 23: Gully Stratigraphy with Glacial Deposits

This public target request via HiWish requested we acquire this image in order to obtain slope measurements and shapes of the gullies on this crater’s wall at the meter scale. Another good way to request for an image from HiRISE is the fact that we have no stereo coverage of this area. This can make for a compelling target.

HiRISE 4K: Layers in Hydraotes Chaos

The objective of this observation is to examine layers in Hydraotes Chaos. This scene is also visible in Context Camera data.

Image cutout is less than 5 km (3 mi) across and the spacecraft altitude was 275 km (171 mi). For full observation details including images with scale bars, visit the source link.

HiRISE 3D: Oudemans Crater Central Uplift

HiRISE coverage gives us an excellent chance to layering in detail compared to Mars Orbiter Camera images.

HiClip mini 4K: The Things that Blow Away

This part of the observation gives us a view of linear dunes in northwest Argyre Planitia. (This is a non-narrated clip with ambient sound.)

HiPOD 6 Sept 23: In Them Thar Hills

Context Camera data shows a dense network of ridges and alcoves at this location. Our main science goal is to figure out what exactly is moving sediment down hillslopes in landscapes like this, but only if high resolution topography is available, which HiRISE can provide. (The technical rationale was to study hillslope-channel coupling in a high drainage density region.)

HiRISE 3D: Tilted Mesas near Athabasca Valles

Tilted mesas, probably due to invasive lava, but in this case showing minimal separation and a fairly close jigsaw fit.

HiPOD 5 Sept 23: Impact-Related Deposits and Flows near Jijiga Crater

The rationale for acquiring this image is to observe how surface flow patterns in the area vary with distance from the proposed parent crater. This is one of several flow feature observations being suggested in the vicinity of the well-preserved Jijiga Crater to the southwest. The crater is named after the town in Ethiopia.

HiRISE 3D: A Recent Crater

Well, “recent” in the geological sense, but we can still see the ejecta pattern clearly in this 3D image.

HiPOD 4 Sept 23: Resistant Material in Olympus Mons Aureole Ridges

The question of how the Olympus Mons aureole formed has wide-ranging implications for Mars paleoclimate, including whether a northern ocean existed. The presence or absence of bedded lava within aureole blocks can help test the merits of a competing hypotheses for the aureole’s formation. These blocks are particularly well exposed and appear to contain layered beds of resistant material.

HiRISE 3D: Once a Landing Site

This was one of the many images HiRISE acquired for the Mars 2020 mission to assess a landing ellipse and to look for potential hazards.
