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.

HiPOD: Steep and Stunning

Even after so many years in orbit, there are still plenty of places on Mars that need the HiRISE treatment. This image was requested because there is little coverage along this portion of Coprates’ south wall. With this observation, we can fill in the gaps and get unique coverage. We can also look for colorful slopes of mafic materials.

HiRISE 3D: Gullies in a Crater in South Aonia Terra

This region has been observed three times by the Mars Orbiter Camera and shows a set of gullies with dark edges apparently originating from layers at a crater edge.

HiPOD: Dune Monitoring in Renaudot Crater

This observation was requested as part of an imaging campaign to monitor frost deposition, evolution, and sublimation. The campaign is designed to capture the onset of seasonal frost, which means images taken near the polar hood have very high incidence angles that are important. The image can also be used for detailed surface measurements.

HiRISE 3D: Branching Fluvial Deposits in Aeolis Dorsa

Observations like these may suggest that Aeolis Dorsa is a paleo-coastal region which may be an important site for exploration in the future.

HiPOD: Climbing Dunes of Aonia Terra

The dunes in this observation appear to climb out of an impact crater and merge with those in the plains to the north. The northeast of the part of the image overlaps with another HiRISE image we acquired in 2007. The crater also has gullies that are partially covered by the dunes.

HiRISE 3D: A Well-Preserved 6-Kilometer Impact Crater South of Eos Chasma

This anaglyph covers the northern part of the crater. Though out of frame, there is also a wide channel that possibly leads to (or from?) the crater.

HiPOD: Dunes in Lyot Crater

This stunning image was obtained to monitor frost deposition, evolution, and sublimation. This observation will also be used for detailed surface measurements. Lyot is a large peak ring crater in the Vastitas Borealis region of Mars, and is about 236 kilometers in diameter and is also the deepest point in the Northern Hemisphere of the planet.

HiPOD: Dunes in Nectaris Montes

Sand dunes in Valles Marineris can be impressive in size, with steep slopes that seem to climb and descend. An enhanced-color cutout shows some of these on the slopes of Nectaris Montes within Coprates Chasma.

The brighter bedforms are inactive while the bigger dunes move over the landscape, burying and exhuming the surface.

HiPOD: Gullies in a Crater in Terra Cimmeria

The objective of this observation is to examine gullies in a crater. Images like this help to increase our inventory and understanding of Martian gullies so that perhaps improved models can be constructed. This particular image is special because the gullies begin at two different levels.

HiPOD: Exposed Bedrock in Eos Chasma

This 47-kilometer (29 mi) diameter crater in Eos Chasma exhibits a central uplift comprised of well-exposed fractured bedrock. HiRISE color imaging reveals fine-scale details in addition to two other key features observed at crater central uplifts.
