HiPOD 1 December 2022: The Pitted Crater
This pit at the center of a northern plains impact crater somewhat resembles ice exposures, but doesn’t look clean. Could it be ice under a thin lag? The CRISM instrument can provide information if ice is being exposed here. We also want to look for active slope retreat of the crater walls.

HiRISE 8K: Possible Chloride Salts in Noachis Terra
Noachis Terra is an extensive landmass in the Southern Hemisphere of Mars, to the west of the Hellas impact basin. Some of the oldest terrain on Mars is in this region.

HiRISE 3D: Dark Ridges over Light-Toned Substrate in the Eridania Region
Details in ridges and light-toned materials could shed insight into how they formed.

HiPOD 30 Nov 2022: Wonders of Mawrth
Often appearing as a candidate landing site, Mawrth Vallis is a topographical wonderland of inverted channels, light-toned rocks and clays. Clay minerals have implications for past wet environments along with the potential to preserve biosignatures. This public request was made to investigate the regional stratigraphy and reasons for the topographic inversion.

HiRISE 4K: Slope Features in the Central Pit of Elorza Crater
We first imaged this central depression in 2007, where we found plenty of recurring slope lineae (RSL).

HiRISE 3D: Streamlined Features and Small Channels adjacent to Ravi Vallis
The rationale for this observation is to look for evidence for overspill of Ravi Vallis. And look at all those craters!

HIPOD 29 Nov 2022: Little Crater, Full of Ice
Ice fill within this impact crater in the North Polar layered deposits may be a site where accumulation could be observed, helping to settle a long-term problem in Mars polar science: are these deposits currently gaining or losing mass? This crater is approximately 136 meters (446 feet) across. But this is likely dry ice, so no drinking!

HiRISE 3D: A Possible Alluvial Fan
An ambiguous feature, possibly a terraced fan with a feeder channel within a crater. Can HiRISE determine if this is really an alluvial fan?

HiPOD 28 Nov 2022: On the Rim of Oudemans Crater
The purpose of this observation is to capture the degraded rim of Oudemans Crater to the northeast. Specifically, we wish to observe the possible impact melt rock on the floor of Oudemans that may have flowed into the canyons to the northeast of the crater. Unlike some craters, Oudemans Crater does not have alluvial fans on its floor. In places, its rim has a terrace.

HiPOD 27 Nov 2022: Martian Morse Code
These dark dunes are influenced by local topography. The shape and orientation of dunes can usually tell us about wind direction, but in this image, the dune-forms are very complex, so it’s difficult to know the wind direction.

HiPOD 26 Nov 2022: Old Salt
What is that “purplish” colored stuff (in HiRISE infrared-red-blue color) with the polygonal fractures in this observation? Scientists think it contains chlorides, like sodium chloride or table salt, or maybe chloride of calcium or magnesium.
These salts can be deposited during the evaporation or water in lakes or playas. These deposits are billions of years old, so it is truly old salt, not a fish tale.

HiPOD 25 Nov 2022: Icy Northern Dunes
Like Earth, Mars has seasonal polar caps that grow in the winter and retreat in the spring, but on Mars the seasonal caps are composed primarily of carbon dioxide (dry ice). Carbon dioxide is the major component of the Martian atmosphere, and a significant fraction of the mass of the atmosphere is cycled through the seasonal caps every year.

The walls potentially expose pristine crustal material. This is an area of interest that could be accessed and is within potential future rotorcraft landing site.

HiPOD 24 Nov 2022: (Crater) Ring of Power
Our science goal with this observation is part of an effort to document the modification style of small impact craters at high latitudes. With a stereo pair and an eventual digital terrain model, we can better understand this ringed structure.

HiPOD 23 Nov 2022: Got Rhythmite?
To do science with rhythmite, one must map rhythmite! A rhythmite consists of layers of sediment or sedimentary rock which are laid down with an obvious periodicity and regularity. With this observation, we want to confirm and extend lovely rhythmite detection in Galdakao Crater.
Galdakao is an impact crater located on the rim of the larger Gusev Crater. It was named after Galdakao, a town in Basque Country, northern Spain.
HiRISE 3D: A Small Delta or Fan
Delta or fan deposits indicate past water activity. HiRISE can resolve sedimentary characteristics such as layering.

HiPOD 22 Nov 2022: Slope Monitoring
This image shows a couple of possible dark flows, which could be recurring slope lineae, carbon dioxide-driven gully activity, or nothing. Little RSL activity and no gully activity has been found in the north to date, so figuring these out would be very useful. The possible flows aren’t very distinct and the lighting similarity to previous images is the best reason to believe they are real.
