HiRISE 3D: Convoluted Folds in Light-Toned Sulfates along Ius Chasma Floor

This was our HiRISE Image of the Day, and we could not resist showing the 3D version, which can help us understand how the folds formed.

HiPOD 6 Jul 23: Cool and Convoluted

HiRISE and CRISM images to west of this locale show these are very cool and convoluted folds in sulfate deposits along the floor of Ius Chasma. CRISM data shows lots of subtle mineral changes so we need high resolution to see any corresponding variations in shape. Part of Valles Marineris, Ius Chasma is about 938 kilometers long.

HiPOD 5 Jul 23: South Polar Troughs

This image was requested through HiWish to map and quantify the dimensions of troughs overlying the massive carbon dioxide ice deposit in the South Pole of Mars. These troughs are likely crevasses formed from glacial flow. Their size and shape provide important information regarding the thickness and size of the polar carbon dioxide inventory, which is in turn important for governing Mars’ climate.

HiRISE Mars 4K (NASA): This Bed o’ Dunes

Matara Crater is a favorite of ours to image owing to the massive and gorgeous sand sheet that dominates the floor. (This is a non-narrated clip with ambient sound.)

HiPOD 4 Jul 23: Mesas Eroding out of a Mawrth Vallis Plateau

These mesas contain bright-toned material which have been found to be clay-bearing in other mesas with both HiRISE and CRISM data. These regions of bright-toned material are layered down to the meter scale and are heavily fractured, reminiscent of the clay-bearing deposits at Mawrth Vallis.

HiRISE 3D: Ejecta in Contact with Knobs and Massifs

The ejecta here originated from Pettit Crater, about 92-kilometers in diameter and named for American astronomer Edison Pettit.

HiPOD 3 Jul 23: Possible Clay Deposits in a Crater Rim

The nearby Her Desher Vallis exposes a clay unit in its valley walls. This observation aims to determine if this unit can be visible elsewhere in the region, such as in excavations in nearby craters. This suggestion targets a 2 kilometer-diameter crater southwest of Her Desher that may have possible exposures, as detected in THEMIS and Context Camera data.

HiRISE 3D: The Central Peak of Taxco Crater

Peaks within craters are formed when material rebounds upward after the initial impact. This can give us a direct look at what was previously underground and learn more about the composition of the rock.

HiRISE Mars 4K (NASA): Chaos, Reconsidered

Aram Chaos is terrain that is located within a massive 280 kilometer-diameter crater. (This is a non-narrated clip with ambient sound.)

HiRISE 3D: Those Fractures!

Today’s HiPOD was too good to not also post as our 3D image of the day!

HiPOD 27 Jun 23: Fractured in Arabia

Also visible in a Context Camera image, this observation shows an interesting pattern of fractures on the floor of an impact crater in Arabia Terra. This could be an indication of incipient chaos formation. Creating a digital terrain model can help us try to figure out what’s going on in this scene.

HiRISE 3D: A Kasei Valles Cataract

At this location the Kasei Valles (north) lava flow feeds into a previous cataract through a narrow channel—should be an interesting site for understanding the behavior of the flow.

HiPOD 26 Jun 23: A Faulted Crater Rim

This observation features a crater rim that has been faulted by wrinkle ridge-like features that trend to the south into the east of the proposed ExoMars landing area. It is possible that the fault plane is visible in the crater rim.

HiPOD 23 Jun 23: Beatific Gullies

These very nice gullies at the northern edge of an impact crater located to the immediate west of Newton Crater, were imaged in a Context Camera observation, so they are worth a closer look in high resolution. We can use this image as a baseline for future observations to check for changes over time. Are there fresh deposits here?

HiRISE 3D: Layers in a Crater North of Hellas Planitia

The objective of this observation is to examine layers exposed near the top of a crater wall. This picture gives a good view of a light-toned layer between darker layers.

HiPOD 22 Jun 23: An Interesting Scene in Juventae Chasma

This image shows dark-toned, windblown sand that surrounds these mounds and yardangs. Other landforms in the area might be possible inverted stream channels? Fans? Odd layer expressions? Our goal is to try to deepen our understanding of the sedimentary rock record and geomorphic history recorded in Juventae Chasma, by looking at areas that are not the famous mounds.

HiPOD 21 Jun 23: An Inverted Channel Feature

This ridge feature show all the morphological signatures of being an inverted channel (sinuous, branching, often flat topped). It sits in the same stratigraphic position as Aram Dorsum, the branching inverted channel system that is an ExoMars candidate landing site region. The aim is to whether these inverted channels have consistent shapes over the whole region or if there is a diversity of forms.

HiRISE 3D: Martian Terrain Sample...in 3D!

If glacial processes were at work here, we want to measure channel depth and downhill direction and also to quantify orientation of any layering.

HiPOD 20 Jun 23: A Crater in Utopia Planitia

The objective of this observation is this crater mound to investigate its structure and origin. This is part of a broader campaign to study the origins of mounds in simple craters in Utopia. Note that the crater might post-date the formation of the small, thin channel we see here, although a part of it does seem to wrap around the southern (bottom) rim.
