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 3 Aug 2022: Not Your Typical Pit Crater
Atypical Pit Craters (APC) are concentrated mostly in the Tharsis region of Mars. A small collection of APC has been identified near Elysium Mons. APC are generally cylindrical or bell shaped with long lived vertical or overhanging walls. APC examples in much older terrain should reveal erosional characteristics and possibly whether they are ancient or formed more recently.

HiRISE 4K: A Cone in Chryse Planitia
The main science objective for this observation is to measure the cone’s size and shape and compare obtained values with other three fields of cones in other areas of Mars. (See link for full cutout and additional info.)
HiRISE 3D: The Floor of Lampland Crater
There are 200-meter thick candidate lake deposits at the deepest point of Lampland. HiRISE can test the flatness of the layers, and look for internal layering.

HiPOD 2 Aug 2022: Beautiful Dunes in Meridiani Planum
This observation features some really nice and well-spaced barchan and dome dunes within in a Meridiani Planum impact crater. We also imaged these dunes twice before, and noted changes in the second picture, so this observation can give us more to look at. Barchan dunes face the wind, appearing curved and are produced by wind action predominantly from one direction.

HiRISE 3D: Ridges in Huygens Crater
Our science goal is to investigate the timing relationship between the wrinkle ridges and the quasi-circular mesas.

HiPOD 1 August 2022: Fractured Material
Also visible in a Mars Orbiter Camera image, this observation captures light-toned rock that appears to be fractured, quite possibly dikes. Dikes can have different composition than the surrounding rock, giving them unique textures and colors. A closer look will give us some insight into the depositional structure, as well as information about its erosional forms.

HiPOD 29 Jul 2022: The Remnant
Arcadia Planitia shows evidence for widespread near-surface ice that appears in different glacial shapes, including polygons and pits. There is evidence for thick buried glacial ice, and this image overlies what appears to be a buried glacier. This observation will assist in mapping out the distribution of the terrain shapes on and in relation to this potential glacier.

HiRISE 10K: Light-Toned Deposits in Noctis Labyrinthus
CRISM observations of this region of the Noctis Labyrinthus formation have shown indications of iron-bearing sulfates and phyllosilicate (clay) minerals. (See link for full cutout and additional info.)
HiRISE 3D: Deposits in Ganges Chasma
Indications of an ancient alluvial fan?

HiPOD 28 Jul 2022: Cones on a Crater Floor in Terra Sirenum
This observation focuses on a few cones in a larger cone field on a crater floor. These cones in particular are singled out because two within this target appear to flow over the southwestern edge of relatively small craters. Verifying this will help unravel the stratigraphy of this crater floor.

HiRISE 8K: Possible Sulfates in Ophir Chasma
Part of Valles Marineris, Ophir Chasma is a large west-northwest-trending trough about 62 miles, or 100 kilometers, wide. (See link for full cutout and additional info.)
HiRISE 3D: A Rimless Crater with Gullies
This observation targets a rimless crater located within a large bedrock plain. This crater is unusual because nearby craters in roughly the same degradation state still possess raised rims.

HiPOD 27 Jul 2022: A Delta-Like Structure at Antoniadi Crater
This delta-like structure on the western margin of Antoniadi Crater indicates a diversity in the nature of water flows here. We know that branched inverted channels in the central part of Antoniadi developed by ground sapping based on their shapes. Such a delta could give us new insights on precipitation-fed runoff.

HiRISE 4K: Diverse Materials in Meridiani Planum
Located 2 degrees south of the Martian equator, Meridiani Planum hosts a rare occurrence of the crystalline hematite, which on Earth often forms in hot springs or in standing pools of water. Could there have been an equivalent in Meridiani in the ancient past? (See link for full cutout.)

HiRISE 3D: Unusual Texture
This crater in the Southern Highlands has some unusual texture, along with a (barely visible) outlet channel. Is there a relationship between the floor deposits and fluvial activity?

HiPOD 26 Jul 2022: Slowly Fading Away
Dust devils form the same way on Mars as they do on Earth, but how long might they take to fade away? Lifetimes of dust devil tracks have been broadly estimated in several cases based on their disappearance in successive images to be on the order of weeks to months on Mars as well as the Earth. Fading rates of dust devil tracks have not previously been measured, nor have lifetimes been reported based on their fading behavior.
HiRISE 3D: Ridges in Cydonia Mensae
This was a HiPOD last week, and now we get to view the scene in glorious 3D! For more info, see the caption: https://uahirise.org/ESP_073454_2100
HiPOD 25 Jul 2022: Slope Features in Palikir Crater
Palikir Crater has long been of interest since we first spotted the phenomena of recurring slope lineae (RSL) in 2013, those dark streaks that appear in the Martian summer, vanish in the winter and then re-appear when the season changes. This image is part of a monitoring sequence as we keep investigating what RSL actually are and how they form.
