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.

HiRISE 3D: The Lonely Mountain
These always make fantastical 3D images! Could the light-toned deposits here be sulfates or other hydrated materials?

HiPOD 13 Jul 2022: Complex Beauty
Is this some kind of inverted fluvial system? Despite some concerns about how dust storm activity might affect this observation, this is still a worthwhile target. We see a beautiful complex of sinuous and intersecting ridges, likely composed of material that was more resistant to erosion than the surrounding terrain. High resolution can help us to decipher the sedimentary and fluvial features.

HiRISE Mars 4K (NASA): Clash of the Chasmas
Accompanies our 4K image post. (This is a non-narrated clip with ambient sound.)
HiRISE 4K: The Boundary of Ophir Chasma and Candor Chasma
Our goal is to investigate the superposition relationship between the layered rocks and wall rock spurs along the boundary between Ophir and Candor Chasmata. (See link for full cutout and additional info.)

HiRISE 3D: Interaction
How does this wrinkle ridge interact with the dune strata?

HiPOD 12 Jul 2022: A Crater with Hummocky Fill
This seems to belong to a class of craters in the Cerberus Plains that was flooded by lava, which was subsequently uplifted and fractured by an unknown process. This class of filled, uplifted and fractured craters is informally called “the waffle.” A combination of volcanic and periglacial processes seems possible.

So, this is the first deep field image from the James Webb Telescope. The light in this picture is 13 billion years old.
HiRISE 3D: Layers in Charitum Montes
The objective of this observation is to examine an outcrop of layers. And ponder if there is such a thing as sand skis.

HiPOD 11 Jul 2022: An Elongated Collapse Pit
Also visible in a Context Camera image, here we take a closer look at an elongated collapse pit in Ceraunius Fossae. This observation can help to tell whether or not there is a subterranean connection to this pit. As an added bonus, the much smaller depression to its south also appears to be another collapse pit. The Ceraunius Fossae are a set of fractures in the northern Tharsis region of Mars.

HiRISE 3D: A Deep Exit Breach
Our goal is to measure slopes and depth of this deep exit breach from a young 5-km diameter crater to constrain erosional hydrologic/sediment transport models.

HiPOD 8 Jul 2022: North Polar Layers of the Fourth Planet
The North Polar layered deposits are a 3-kilometer thick stack of dusty water ice layers that are about 1000 kilometers across. The layers record information about climate stretching back a few million years into Martian history.
HiClip mini 4K: Of a Martian Dreamscape
Has it been a year since we last made a HiClip mini 4K? No way! (This is a non-narrated clip.)
HiRISE 3D: Gully Stratigraphy with Glacial Deposits
To get a better handle on the morphology (shape) of these gullies, a 3D pic can aid with slope measurements at meter scale.
Oh, and looks awesome.

HiPOD 7 Jul 2022: Weathering over Time
This image reveals an impact crater, 9 kilometers in diameter, with a central peak. Impact craters of various sizes and ages can be found across the Martian surface. Each impact crater on Mars possesses a unique origin and composition, which makes the HiRISE team very interested in sampling as many of them as possible!
HiRISE 3D: Tilted Layers in the Electris Region
This is an interesting feature that appears to be a large anticline that is crosscut by wrinkle ridges. We want to investigate the structure and timing relationships.

HiPOD 6 Jul 2022: Remembrance of Dust Devils Past
HiRISE sees many dust-devil tracks on Mars, but rarely captures an active feature because the images cover such small areas and because the typical time of day near 3 p.m. is past the peak heating and dust-devil activity. In this 2008 image in the Amazonis region, we got lucky, although not lucky enough to capture the whole swirl in the color strip.
HiPOD 5 Jul 2022: Better Preserved on Mars than on Earth
In many ways, Mars bears remarkable similarities to Earth, but in some ways it is drastically different. Scientists often use Earth as an example, or analog, to help us to understand the geologic history of the Red Planet.
HiPOD 4 Jul 2022: Scars of Erosion
This large crescent dune in Kaiser Crater shows the scars of many types of seasonal erosional activities. Along its downwind slope are large gullies which are active during winter, when frost drives dune material downslope, carving out channels and creating fan-shaped aprons.
HiRISE 3D: Fascinating
There wasn’t much by way of a science rationale for this observation in north Arabia Terra, so let’s just soak in the 3D weirdness without comment.
