HiPOD 10 Apr 23: A Chain of Layered Mounds in Chryse Planitia
This landform shows distinctive layering in Context Camera images, and is similar to other buttes to the far northeast that have been observed to have Mawrth Vallis-like stratigraphy. Understanding the connection between these landforms is vital to our knowledge of their formation.

HiPOD 7 Apr 2023: Climbing Dunes Escaping a Crater in Aonia Terra
This image from a stereo pair and DTM reveal one such location where sandy bedforms appear to be crawling out of a crater. This crater is near 1 kilometer deep and shows steep slopes particularly on the south face.
HiPOD 6 Apr 2023: Bumpy, Expanded Craters
The expanded craters in this image have an unusually bumpy texture in the outer apron where the sublimation occurred. The bumps are too large to be boulders. This suggests that the ice had concentrations of other material.
HiPOD 5 Apr 2023: Waxing and Waning Winds
A dune’s steepest area, called a “slip face,” indicates the down-wind side of the dune and its migration direction as driven by local winds. At this location, there are many dunes influenced by eastward winds that were draining into Hellas. Meanwhile, other locations show that migration had shifted towards the opposite direction to the west.

HiPOD 4 Apr 2023: Candidate Mud Volcanoes in Utopia Planitia
There are many processes that can form such landforms, most notably hot lava. However, mud ejected from beneath the surface (through different geologic mechanisms) could also be a possibility.
HiPOD 3 April 2023: Looking at the Crater Half Full
With this observation, scientists can learn more about the nature of these deposits. The crater offers an opportunity to gain more information about the flowing behavior of these deposits and their thickness given that the crater size can be used to estimate its depth.

HiPOD 31 Mar 2023: An Olivine-Rich Massif in Northeast Hellas Planitia
This observation targets banded terrain located in an olivine-rich massif in the Hellas Basin. The olivine-rich massifs have been interpreted as ejecta blocks excavated from the lower crust/upper mantle by the impact. This observation will help to investigate deep crustal, or mantle materials not otherwise exposed at the surface.
HiRISE 3D: Channels near Huygens Crater
The objective of this observation is to examine a group of channels along a slope. They are mostly parallel to each other.

HiPOD 30 Mar 2023: Mounds in Oxia Colles
This landform shows distinctive layering in Context Camera images and is similar to other buttes to the far north east which have been observed to have Mawrth-like stratigraphy. Understanding the connection between these landforms is vital to our knowledge of their formation. Highest resolution will allow for viewing of sedimentary structures.

HiRISE 3D: O Lovely Dunes
This observation is part of an ongoing campaign to to aid in classification and volume estimates of dunes in USGS global dune database. Sand dunes are among the most widespread aeolian features present on Mars.

HiPOD 29 Mar 2023: From Smooth to Collapsed
This region marks a transition from the smooth to hummocky surface typical of the Arsia Mons western summit to a collapsed terrain. The formation of the collapsed terrain appears to represent some of the youngest activity on the western flank and understanding the formation of these two units is critical for interpreting the developmental sequence of the shield.

HiRISE 3D: A 1-Kilometer Crater Buried by Candidate Lake Sediments near Deepest Point
This observation can constrain lake timing and lifetime if the sediments partly burying the crater can be confirmed as actual lake sediments.

HiPOD 28 Mar 2023: Hills in Eos Chasma
These hills are surrounded by small gullies, where there is likely activity related to recurring slope lineae, perhaps even slumps, which are masses of loosely consolidated material or rock layers that move a short distance down a slope. These features are similar to well-monitored hills in Juventae Chasma. Eos is located in the southern part of the Valles Marineris canyon system.

HiRISE 3D: Crater Floor in Sinai Dorsa
Most late-stage lake deposits are low elevation. Is this candidate lake deposit in crater high on Tharsis an exception?

HiPOD 27 Mar 2023: Ridge Meets Butte
The curved ridge is darker than surroundings and appears to be an inverted stream channel. At this location, the inverted stream is interrupted or diverted by the presence of a couple of buttes or knobs. The main objective here is to get very high resolution coverage of the inverted stream materials (sedimentary rock?) and to include the buttes and attempt to discern their origins and relations to the old stream channel system.
HiRISE 3D: Downwind Hellespontus Regional Barchan Dunes
Our science goal is look for and measure seasonal changes due to wind processes since earlier images.

HiPOD 24 Mar 23: On the Hunt for RSL
Two previous images of this area showed possible recurring slope lineae (RSL) on the north- and northwest-facing ridge that has already faded. This public suggestion was acquired to determine the seasonality of these RSL and to confirm if this is a good candidate RSL site.

HiPOD 23 Mar 23: A Flow Margin in Phlegra Dorsa
Some of our images, like this one, are acquired so that we can overlap with adjacent pictures to get enough coverage to create a continuous digital terrain model. We can also resolve fine flow textures and fractures. With the Context Camera as a “ride along” we can also generate regional stereo coverage of the area for a more complete view.

OT: Does anyone use the Mastodon app for iPadOS and have a problem uploading an image? We keep getting server errors when uploading, so we have to use a web browser to post. But not sure if it’s the app or counter.social itself.
