HiRISE 3D: Not Quite Mount Doom
These cones were interpreted to be volcanic in origin despite a distinct lack of volcanic activity in this area. Whether volcanism has occurred here recently or not is a key constraint on polar history and has implications for any possible basal melting of the polar ice deposits that may have occurred.

HiPOD: Light Toned in Aureum Chaos
The objective of this observation is to examine a light-toned, layered butte in a region of chaos. The field of view also inculdes several small outcrops of light-toned deposits. The OMEGA experiment on Mars Express discovered clay minerals in a variety places in Aureum Chaos. Clay minerals need water to form, so the area may once have contained large amounts of water.

HiRISE 3D: A Potential Landing Site in the Coprates Region
This image shows a central hill exposing crustal bedrock enriched in low calcium pyroxenes and possibly in clays, located 2 km north of a proposed landing ellipse.

HiPOD: Ridges in Hellas Planitia
Also visible in Context Camera data, the objective of this observation is to examine curved ridges and a network of straight ridges. One area of the curved ridges appears superposed on a section of the very eroded rim of an impact crater.

HiRISE 3D: Utopia Planitia
In this image, we see when Mars looks less like the “plains of nowhere” and more like popped blisters.

HiPOD: Ridges in Tempe Terra
The objective of this observation is to determine the nature of a network of ridges. The ridges are very regular in height and width and seem to be associated with a certain layer. The layer above the ridges has a darker-tone. Many of the ridges are joined to other ridges, some at close to right angles.

HiRISE 3D: A Knob on Polar Layered Deposits
Our goal is to determine the origin of this knob, in an area not well observed: is it impact related?

HiPOD: A Channel and Crater in Hesperia Planum
The objective of this observation is to examine a channel and an impact crater. The channel is narrow, and it maintains its width for a long distance and may be related to volcanism. Hesperia Planum is a broad lava plain in the southern highlands of Mars with a moderate amount of cratering indicating an intermediate geological age in Martian history.

HiPOD: Not Madame Web
This image is of a hill in the Nepenthes Mensae region of Mars. The hill and surrounding ground is covered by numerous connecting ridges that create patterns resembling spiderwebs.
These ridges likely formed as minerals accumulated within underground cracks. Some of the ground surface was then removed by wind and/or water, revealing the mineral-filled cracks.

HiRISE 3D: The Lonely Polar Crater
This feature was seen in a Context Camera image, but not well resolved. Until now.

HiPOD: Hills and Rings
This image shows a group of hills as well as ridges that form circular patterns that resemble rings. The origin of these features is not fully understood and may be related to the eruption of magma or mud, or alternatively due to salt rising to the surface.

HiPOD: Channels in the Southern Mid Latitudes
The objective of this observation is to examine small channels that have interacted with a impact crater. Also visible in Context Camera data, the channels may have changed direction when they came in contact with the crater.

HiPOD: Mesa Stratigraphy at Terby Crater
A 2 to 3 kilometer sequence of stratigraphy exposed across three mesas in the northeastern portion of Terby Crater captures a diverse range of sedimentary rock types that include deposition across all of the three major Martian geologic eras: Noachian, Hesperian and Amazonian. These epochs date back billions of years.

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.

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.
