HiPOD: Searching for Distant Secondary Craters

HiRISE has been imaging this field of secondaries, working outwards to see how far away they formed. This image, around 20 kilometers from the primary impact, has only a few such secondaries and must be approaching the outer edge of the field.

HiRISE 3D: Mars Psychedelia!

If you thought a regular 2D image of the terrain in the South Pole of Mars was weird, see it now in 3D!

HiPOD: A Song of Ice and Tectonics

The ice deposits here are probably no older than a few million years, which is recent in geological terms. However, we can observe that these deposits have been affected by even more recent movement of the crust (the curving trough) that clearly post-dates the ice deposits because it is cutting through them.

HiRISE 3D: An Outlet Channel in Cerberus Palus

The rationale for this image an outlet channel was to get coverage for evaluating (ancient) lava flux.

HiPOD: Mars Atmosphere Fights Back!

In this image, we can see multiple dark spots corresponding to numerous new craters. We can also identify a slightly larger crater, and a number of smaller ones, particularly in a cluster next to it. As the impactor was falling towards Mars, the friction with the atmosphere led to the body fragmenting into smaller pieces shortly before striking the surface creating this notable pattern.

HiRISE 3D: A Crater in the South Polar Layered Deposits

This crater has not been imaged by the Context Camera or HiRISE before, and adding a more accurate diameter measurement is useful for determining the age of the surface of the SPLD and current accumulation rates.

HiPOD: Mars Mysteries: Unveiling the Icy Craters

In some cases, these patchy icy deposits and meter-sized blocks of ice are thrown out of the crater and form part of the ejecta. This image shows one such example of a 13-meter (43 feet) diameter crater in Arcadia Planitia where ice was exposed both in the crater interior and ejecta.

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 8K: Possible Hematite and Kieserite in Capri Chasma

TES has detected gray hematite and CRISM sees kieserite along this crater wall and floor.

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.
