HiPOD: Light-Toned Materials within Iani Chaos

The objective of this observation is to get high resolution image to see more details about the light-toned deposits: could they be more sulfates or other hydrated materials? Iani Chaos is a region of chaos terrain at the south end of the Ares Vallis outflow channel. The chaotic terrain is believed to have formed by the removal of subsurface water or ice, resulting in flooding at the surface.

HiPOD: Gullies in a Crater near Newton Crater

The objective of this observation is to observe gullies in a crater. Pictures like this will help us increase our knowledge of the distribution of Martian gullies. Some of the gullies have quite wide, branched alcoves, and there are ridges of material at the base. The floor of this crater is covered with pits and contains some small ring mold craters.

HiRISE 3D: Yardangs in the Aeolis Region

Hypothesis: Three different generations of yardang-forming materials are recorded here. Alternative: One generation of deposits, but multiple directions for strong-wind erosion.

HiPOD: A Source of Stratified Fan Material

This public suggestion from HiView requested an image to help determine the relationship between the crater wall and fan deposits on the crater floor. The stratified fan material in the southeast quadrant of Baltisk Crater may have its source in the wall where glacial landforms have been observed. Or, the stratified fan material could have been transported into the crater and prior to deposition.

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.

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.

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.
