HiPOD 17 Jul 23: Channels in Arabia Terra

The channels featured in this image are located in Arabia Terra. These channels were carved long ago, when water flowing down from the broad, elevated landforms to the north travelled southward across the land surface, eventually eroding the underlying rock and sediment as it approached the northern wall of Mamers Valles.

HiRISE 10K: On the Floor of Ritchey Crater

Dark slope lineae was visible in previous images, so we want to monitor and see if and how they are changing.

HiRISE 3D: Is It Mars or Jupiter?

Of course, it’s Mars. Layers in a trough in the North Polar layered deposits, to be exact.

HiPOD 14 Jul 23: Tongue-Shaped Flows and Gullies in Terra Cimmeria

Also visible in a Context Camera image, the objective of this observation is to examine tongue-shaped flows and gullies in on the west wall of an impact crater. The flows are somewhat hollowed out, like they have lost most of their ice. Is that the case here?

HiRISE 8K: A Portion of a Ridge in Northwestern Antoniadi Crater

Also visible in a Context Camera image, this observation shows a possible fluvial ridge (inverted channel) sediment exposure. It terminates to the east in a sediment fan.

HiRISE 3D: A Glacier Tongue inside an Impact Crater

There is a lot going on with this image: a crater cut by a fault, glacial fill and erosion.

HiPOD 13 Jul 23: Dunes in Tyrrhena Terra

The objective of this observation is to examine a few dunes near small craters. If any movement or other changes occur, one can easily tell because the dunes are associated with these small craters. This scene can be found in a Context Camera image. Tyrrhena Terra is northeast of the Hellas impact basin and covers 2,300 kilometers at its broadest extent.

HiRISE 4K: Slopes in East Melas Chasma

Potential recurring slope lineae was detected in earlier images, perhaps associated with the sulfate-rich layers we find here.

HiRISE 3D: Crater vs. Graben!

Was a graben minding its own business when the crater was formed? One goal is to measure the erosion of one rim compared to the other.

HiPOD 12 Jul 23: A Silica-Rich Deposit Northwest of Ariadnes Colles

CRISM spectra data indicate the presence of silica deposits in this region. The geologic context is key for determining the origin (whether wind-driven or bedrock) of these deposits, and their distribution with the crater. This could give insight into hydrothermal processes in Eridania Basin.

HiPOD 11 Jul 23: A Ridge and Channel through Ice Rich Terrain

A sinuous ridge and associated channels emerge from ice-rich material, which has subsequently been disrupted by a young impact crater. The sinuous ridge appears to pay little regard to topography, so high-resolution analysis of topography and stratigraphic relationships to young ice deposits will allow us to better understand whether it formed by subaerial or subglacial water flows, or as a moraine.

HiPOD 10 Jul 23: An Infilling of Lava?

This observation was requested to support an ongoing SHARAD investigation in this region. More coverage of the surface will assist in determining what is infilling this low-lying region.

HiPOD 7 Jul 23: Banding on the Wall

Our objective is not just to image the banding, or perhaps layering, exposed on the crater wall, here, but also to capture a full resolution view of the variety of textured surfaces inside and outside the crater. At Context Camera image scale, all of these surfaces are fairly rugged and pitted. Are some of these lithified sediments and regoliths? Is there any hint of lava or intrusive igneous rock here?

Our goal with this observation is to re-image these dunes to see if they have moved since an image acquired in 2012 and to get a higher-res view of their morphological features.
