HiPOD: The Dunes of Change

The Mars Orbiter Camera imaged these dunes in 2000, so now we can learn what a multi-decade dune movement average is by taking a new observation to create a MOC-HiRISE temporal pair. With MOC providing a long baseline to newer HiRISE images, we can build up global averages of the effects of wind on the environment. Two decades is long enough that the dunes will have moved noticeably between MOC and HiRISE.

HiPOD: Fluvial Erosion in Harmakhis Vallis

This observation was requested by a Mars class to examine fluvial processes in one of the large channels leading into Harmakhis Vallis. The requested image is in a corner pointing opposite of the flow, possibly creating an eddy/turbulent area. The goal is to get a high resolution look for shoreline markings and erosion effects. Harmakhis Vallis probably formed by a combination of surface collapse and flowing water.

HiRISE 3D: Channels in Hebrus Valles

The objective of this observation is to examine channels and streamlined features. The main channels seem to go into a short trough.

HiPOD: A Candidate Recent Impact Site

Why do we initially say “candidate”? Before HiRISE acquires an image, the Context Camera on MRO might observe something that could be an impact, but their resolution is not like ours. In one of their images, there was a large diffuse dark blast zone that was not present in an earlier observation, so that team asked HiRISE to acquire a picture to confirm if this is an impact crater.

HiPOD: Layering in Arabia Terra

The objective of this observation is to search for layering in Arabia. In Context Camera data, the layering shows up in buttes, ridges, and the edges of mesas. Our image may be able to see many more of these layers. This image will also help us to determine the horizonatal extent of layering in the region.

HiRISE 3D: Ridges in Huygens Crater

We acquired this image to investigate the timing relationship between the wrinkle ridges and the quasi-circular mesas.

HiPOD: Channel, Fan, Crater

The objective of this observation is to examine a channel on a crater wall, where a fan has formed at the base. Images like this, also found in Context Camera data, may help us better understand how craters are degraded. This particular crater is one of many located to the northwest of the massive Hellas impact basin.

HiRISE 3D: A Partly Filled Impact Crater near Nicholson Crater

This anaglyph shows an infilled and possibly exhumed crater. HiRISE resolution can examine the shape of the crater fill and any wall layering.

HiPOD: A Circular Landform within an Impact Crater

This circular formation appears to have the land around it sloping to its edge. The formation then looks to rise out of the ground with various others different formations around it. There also what appears to be a small crater on the top. When viewing this area using infrared background, the land formation has several markings on one side more than the other.

HiRISE 3D: Light-Toned Outcrops in Aurorae Chaos

HiPOD: A Patchy Outcrop of Light-Toned Materials

This observation targets a small region of patchy light-toned materials visible in Context Camera images. These outcrops are small, precluding geomorphological analysis and assignment of a stratigraphic position relative to the surrounding materials. The shape of this material closely resembles sinuous, light-toned outcrops elsewhere in Terra Cimmeria.

HiPOD: Bedrock Exposures in Nirgal Vallis

This observation covers two tributaries and the main channel of Nirgal Vallis. The channel is approximately 610 kilometers long and is named after Nergal, the Babylonian god of war and counterpart to the Roman god of war, Mars. Mars Orbiter Camera image show light-toned bedrock; our high resolution picture can gives us a better view of the channel form and bedrock stratigraphy.

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.

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.
