HiPOD: The Chaos of It All

The science rationale for this observation was to look at stratigraphic relationships in amongst chaos blocks and adjacent geological units. HiRISE resolution can also help us to examine fine-scale layers and a digital terrain model can be used to constrain those stratigraphic relationships. The scene is located in Hydaspis Chaos, where many large, ancient river valleys are found.

HiPOD: Delta or Fan?

Delta or fan deposits indicate past water activity. HiRISE can resolve sedimentary characteristics such as layering, stratigraphic relationship to the surrounding geologic setting or distributary channels that cannot be resolved by other camera experiments.

HiRISE 3D: Hillslope Shapes near Holden Crater

What was the source of the runoff that helped shape these hills and their slopes?

HiPOD: Gully Study

The gullies and their small fans in this impact crater are suggestive of recurring slope lineae. Are there fresh deposits here? The crater is less than 5 kilometers in diameter and the scene is located in Terra Cimmeria, to east of the massive Hellas impact basin.

HiRISE 10K: A Simple Crater

Sometimes, the nicest pictures we acquire don’t need a long explanation, so we are parking this image of the northern part of large, less than 5-km diameter crater for your visual enjoyment.

HiPOD: Layered Features in Northern Mid-Latitudes

The objective of this observation is to examine several sets of layered features. Some are dipping and others are horizontal. Some are in craters, and another within a depression. The scene can be found in Context Camera image data.

HiRISE 8K: In Tyrrhena Terra

Tyrrhena Terra is located in the cratered highlands of the Southern Hemisphere of Mars. It is one of the regions where instruments like OMEGA and CRISM (the latter also on the Mars Reconnaissance Orbiter) have identified numerous detections of hydrated silicates.

HiRISE 3D: An Eye on You

From the rationale: “This feature has been suggested to have formed after Athabasca Valles was first carved and thus is evidence for multiple floods. The idea is hooey, but CTX is not sufficient to prove that.”

HiPOD: Fossae East of Arsia Mons

Our science goal with this observation is to examine a vent-like structure in the floor of a graben that is part of a larger fossae system partially buried by numerous flows. We want to determine the relationship of the possible vent to the graben and adjacent flow units, and look for any deposits related to the vent.

HiIRSE 4K Possible Olivine on the Floor of a Crater in Northern Hellas Planitia

Olivine is a common silicate mineral that comes from magma generated in the mantle of Mars (this same process occurs on Earth as well).

HiPOD: Fed by Fans But from Where?

With this observation, we see some candidate lake deposits possibly fed by alluvial fans in the distant past. At high resolution, we can check for layers and layer tilts to test a lacustrine hypothesis. Tilts more than 2 degrees suggest the origin is *not* lacustrine, but rather from a distal alluvial source.

HiRISE 3D: Light-Toned Stratified Materials in Hebes Chasma

Hebes Chasma is an isolated chasma just north of the Valles Marineris canyon system of Mars. This image is northwest of the central mound located there.

HiPOD: Near the Deepest Point

We acquired this image to study layered materials in a low albedo (light-reflective) region near deepest point of an unnamed impact crater north of the Becquerel Crater. There might be possible embedded craters here, which is interesting because the host crater is relatively young, and the layers could be lake sediments.

HiRISE 3D: A Candidate Landing Site in Mclaughlin Crater

This was a leading candidate site for the Mars 2020 rover and other future missions. The floor of McLaughlin Crater contains layered carbonates and clay minerals suggesting of an ancient lacustrine setting.

HiPOD: Among Hale Crater’s Central Peaks

This image is part of a new slope monitoring sequence as we try to observe any activity after a dust storm to compare with a previous Mars year sequence. Are any recurring slope lineae longer or more dense? Hale is about 150 km in diameter and located north of the Argyre basin.
