HiRISE (NASA)
HiRISE is a high resolution camera onboard the Mars Reconnaissance Orbiter (NASA). We take images of the surface of Mars. Based out of UArizona in Tucson.

HiPOD 4 Oct 2022: Layers in Nia Chaos
Chaotic terrain, where the landscape is cracked, uneven and jumbled, doesn’t exist on Earth but only on Mars. Such terrain might be linked to past water activity. This image shows a part of the eastern limit of Nia Chaos, located in Candor Chasma. Our goal is to study the placement relations of the layers with adjacent deposits.
BTW, "Nia Chaos" is an AWESOME rock band name. Or Bond villain.

HiRISE 3D: Group of Cones with Summit Depressions
One of several image requests in this general part of Coprates Chasma to examine cones with summit depressions. Can they all be inferred to be volcanic?

HiPOD 3 Oct 2022: Crescent Forms in Aeolis Planum
Crescentic forms in what is known as the Medusae Fossae Formation bedrock might be sedimentary structures indicative of barchan dune sedimentation. Or not. We have little bits and pieces of clues in this area from some of the previous HiRISE, Context Camera and Mars Orbiter Camera coverage, but this additional image can help us to get closer to an answer.

HiPOD 29 Sept 22: Gullies and Boulder Tracks
The formation of gullies on Martian slopes is still under debate. Potential mechanisms include the melting of surface water ice, groundwater outbursts, or dry mass wasting processes (landslides).
HiPOD 28 Sept 22: The Ever-Changing Swiss Cheese of Mars
Mars has a small South Polar cap of carbon dioxide ice. Although this cap persists year round, it is always changing: it has pits and mesas that in some places resemble a slice of Swiss cheese. The pits are expanding because the carbon dioxide is sublimating, but in other places new carbon dioxide deposits are building up on flat ground.

HiPOD 26 Sept 22: Landforms in Ares Vallis
Ares Vallis is a large valley that was carved billions of years ago by water flowing across the surface of Mars. This image shows an area where the flowing water may have stripped away some of the rocks and soils at the bottom of the valley, leaving behind the ridge-like formations.
HiRISE 3D: Down the Gully
The north-east facing side of this massif has a gully with a bright deposit. Are there gullies on the southwest facing side, and do they have bright deposits? Bright deposits have been proposed to be evidence of recent surface water.

HiPOD 23 Sept 22: Channels, Channels, Channels!
These late-stage channels incise fan deposits in this observation. Are they glacial-melt-sourced? It is not clear what the substrate of the late-stage channels is at this location. Are the fan deposits channelized or perhaps un-channelized sediments?

HiRISE 10K: A Mesa in Southwest Nili Fossae
Images from other spacecraft missions show that this mesa is mix of diverse lithology, probably stemming from the early Noachian epoch on Mars, about 3.7 to 4 billion years ago. (See link for full cutout.)

HiRISE 8K: Colorful Surface near Nili Fossae
This enhanced-color image shows a surface with diverse colors just southwest of Nili Fossae. The color diversity of this mesa suggests that the surface has a varied composition, perhaps recording chemical processes of ancient Mars. (See link for full cutout.)
HiRISE 3D: Steep Southern Slopes
In Coprates Chasma, of course. Up to now, we’ve had very little coverage along this portion of Coprates’ south wall.

HiPOD 22 Sept 22: Layers in in Labeatis
Also visible in a Context Camera image, the objective of this observation is to examine layers in a the wall of a trough in Labeatis Fossae. This view is one of the best of layers in the Lunae Palus quadrangle of Mars, in the Northern Hemisphere. Labeatis is about 1,560 kilometers in length.

HiRISE 3D: Variety of Spider Terrain
Even without 3D, the terrain of Mars is very, very weird.

HiPOD 21 Sept 22: Even Craters Need an Outlet
This outlet channel from the sharp-rimmed crater to the east of this location is itself modified by subtle side channels. Do these side channels postdate a crater to the northwest? A stereo pair will help to constrain eroded volume and determine timing, which in turn would constrain any runoff production mechanism for their formation.

HiRISE 3D: The Icy Scarp
This scarp (cliff) shows us some nice exposure of ground ice. Our goal is to monitor any changes due to sublimation.

HiPOD 20 Sept 22: Sinuous Ridges near Juventae Chasma
A previous image taken in 2007 shows very finely branched channels running west to east. Here, inverted channels crosscut negative-relief channels, and the stratigraphic relations are complex. A stereo pair will help to unscramble the relationship to local topography, determine influence of present-day tilt, and to identify slope-area relations and drainage divides.

HiRISE 3D: 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. These ridges seem to be associated with a certain layer.

HiPOD 19 Sept 22: Channels in Nilokeras Mensae
The objective of this observation is to examine a point where several channels join. Some of the channels may be younger than others because they form hanging valleys. HiRISE shows much more detail than previous Context Camera images. (A mensa is a flat-topped prominence with cliff-like edges, i.e. a mesa.) The HRSC instrument on Mars Express has imaged stratus clouds over this region.

HiPOD 15 Sept 22: The Way the Wind Blows
Our primary objective with this observation is to look at changes over several Mars years since earlier images we obtained in 2008. Bidirectional wind regimes were detected here so tighter imaging will help understand when east or north blowing winds dominate. These dunes are within an impact crater in the Cerberus Fossae region, in Elysium Planitia.
