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 25 May 2022: Possible Impact Melt in Terra Sabaea
Nighttime and daytime infrared images from THEMIS suggest a consolidated deposit in the floor of this ancient crater in Terra Sabaea, potentially with some bedrock exposure. Our goal is to examine the relationship between the surrounding crater floor and the deposit and to differentiate the deposit from nearby volcanics.

HiRISE 4K: An Inverted Channel in Arabia Terra
HiRISE was requested to obtain this image in order to investigate the stratigraphy of the ridge and the depositional history of the river system. (See link for full cutout and additional information.)

HiRISE 3D: Flow Features in Zilair Crater
Zilair is about 47 kilometers in diameter and this scene cover part of the north end of the crater. Were these fluvial processes at work here?

HiPOD 24 May 2022: A Rising Ridge
This observation focuses a ridge that is standing above the old lava surface of the floor of Echus Chasma. What is this ridge doing here? Is it preexisting material surrounded by lava? Is it material pushed up at a restraining bend? If the ridge is not lava, it may have colorful flanks.

HiRISE 3D: The Center of Crommelin Crater
When you have an opportunity to view such exquisite layering, you certainly don’t want to pass up the chance for a stereo pair to create a stunning 3D image!

HiPOD 23 May 2022: Fans and Polygons
This is a place where fans emerge relatively late in the Martian spring from polygonal cracks owing to the process of sublimation. Good lighting may make it possible to catch an eruption of material that will darken the surrounding area before fading over time and moved about by the wind. This scene is at the Martian South Pole.

HiRISE 3D: Bedrock within an Impact Crater
A nice place to survey the bedrock at high resolution. This scene is located in Hesperia Planum.

HiRISE 3D: A Small Crater Exposed via Erosion
Erosion has exposed the rim area and a small part of the floor of this impact crater, enabling the study of impact-induced layer disruption beneath the ground’s surface.

HiPOD 19 May 2022: Sedimentary Rocks inside Terby Crater
The sedimentary history of Mars is important to understanding climate change and the evolution of Mars. Sedimentary rocks consist of fine particles carried by the atmosphere and/or water and deposited in generally flat-lying layers, which become indurated (turn into rock) over time.

HiPOD 18 May 2022: Rapid Changes on the North Polar Cap
The purpose of this sequence of images is to understand rapid albedo (brightness) changes seen at this time of year (late northern summer) on the Martian polar cap.

HiRISE 3D: Exit Breaches in a Small Fresh Crater
With this 3D pic, we can quantify exit breach geometry for hydrologic modeling and erosion modeling. Plus, it looks pretty cool.

HiPOD 17 May 2022: Cliffs of Crumbling, Layered Sediments
Massive deposits of sediments rich in hydrated sulfates are found in central Valles Marineris. Such deposits on Earth are soft and easily eroded, and that appears to be true on Mars as well.
HiPOD 16 May 2022: Dunes in Meridiani Planum
HiRISE monitors dune fields across Mars to track how they are changing. The mobile sand also cleans dust off of the bedrock in inter-dune areas, providing good views of the bedrock structures and colors.
Here we see subtle color differences between layers, and a dense network of fractures. The dunes, in contrast, are uniformly dark and relatively blue in enhanced color.

HiPOD 13 May 2022: The Mottled Surface of Gale Crater Ejecta
Also visible in Context Camera images, this might be an “erosional window” down into the ejecta deposit. Perhaps some of the material is superimposed on the ejecta blanket. What does the mottling tell us about the ejecta, if anything? Differing rock characteristics or maybe patches of impact melt?

HiRISE 10K: The Caldera of Olympus Mons
HiRISE is not able to capture the entire caldera at the summit of Olympus Mons, so we try to get as many images as possible to create a potential mosaic. This image shows the northeastern rim of the caldera, and our main goal is to track any potential changes from previous images. (See link for full cutout and additional info.)
