HiPOD: A Landslide Deposit in West Candor Chasma

This observation is located between previous coverage to the immediate east, north, and northwest. This is a critical area to address a question: is the landslide deposit superimposed by younger light-toned layered rock, or is the light-toned material part of the original landslide deposit (or even a later landslide deposit on top of it)?

HiRISE 3D: Chutes and No Ladders

This image was requested to re-image gully/avalanche chute features visible in a MOC image but cloudy in a previous HiRISE picture.

HiPOD: A Small Channel South of Mangala Valles

This small channel extends south of Mangala Valles for a few hundred miles where in places, it is buried by crater ejecta or lava. The question is, is it fluvial or magmatic? Another question is, if fluvial, could water have flowed from a paleolake further south here? Context Camera images show two distinct terraces where different levels of water or lava flowed through the channel.

HiRISE 4K: Polygonal Patterned Ground

From a distance, the floor of this crater looks like a giant honeycomb or spider web. The intersecting shapes, or polygons, commonly occur in the northern lowlands of Mars.

HiRISE 3D: Landforms on the Floor of Barnard Crater

There was not much way of science rationale, but the scene alone is certainly worth a post.

HiPOD: Channels in Southern Mid Latitudes

The objective of this observation is to examine a group of channels. Some are very small and one is much larger. The small channels connect to the larger ones. It may be that a wide valley was created, partially filled with sediment and then later the sediment was eroded by the channels we now see. Pictures like this may help us understand the fluvial history of this place.

HiClip mini 4K: No Country for Earth Men

The scene is located south of Eos Chasma in a relatively flat area, although what we see here would be daunting for even the most hardened explorer. (This is a non-narrated clip with ambient sound.)

HiRISE 3D: A Beautiful Bounty of Craters

Secondary craters are stratigraphic markers. This image will help provide detail about the shape of the ejecta and bowls of these secondary craters, which can tell us in turn about the impactor direction.

HiPOD: Scour Pits Southwest of Olympus Mons

Scour pits are poorly understood erosional features. Generally, scour pits are found in and around the enigmatic Medusae Fossae Formation (MFF). High resolution images of the scour pits located in Olympus Mons can help us answer questions about the formation and extent of the MFF by comparing what this area has in common with the MFF to allow scour pits to form.

HiPOD: At the Edge of an Ejecta Blanket

A CaSSIS image shows that this ejecta blanket has incredible color diversity. The objective of this suggestion is to acquire additional coverage with HiRISE and to learn more about the diverse composition here.

One of the most eye-catching aspects of this scene are the intricate swirls that these layers form.

HiPOD: Light-Toned Chaos

Often times, observations are planned to fill in HiRISE coverage where there is image data from other instruments, in this case, from CRISM, also on MRO. Aram Chaos is a 280-kilometer diameter impact crater at the eastern end of the massive Valles Marineris canyon system. The mineral hematite has been located here, signature of a once aqueous environment.

HiPOD: Dunes Tell in Bonestell

This observation was requested to obtain an image for dune monitoring and the onset of seasonal frost within Bonestell Crater, a relatively young crater located in Acidalia Planitia. Dust blown into the crater and the downslope movement of fine materials from the rim are slowly modifying the crater features. This image can be useful for detailed surface measurements.
