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 30 Dec 2022: Strange Patterns in Echus Chasma
This image shows bright and dark patterns with curving boundaries, a good example of Mars art. What caused this appearance?
This region of Echus Chasma has been flooded by lava flows that produced rough and smooth surfaces. The rough areas then trap bright dust, creating the contrasts in brightness.

HiRISE 3D: A Mid-Latitude Crater with Steep Slopes
Come on, how can we *not* include an impact crater with our 3D pics this week?

HiPOD 29 Dec 2022: An Elevated Crater in the Apollinaris Mons Region: Volcanic or Impact-Related?
Impact craters are very common on the surface of Mars. However, when a circular depression is visible on the summit of a mound or an elevated landform in general, careful analysis is needed to identify whether the crater is created by an impact or by volcanic activity.
HiRISE 3D: Light-Toned Hydrated Deposits in Noctis Labyrinthus
Lots of CRISM images show these deposits contain hydrated minerals. This image will fill in a small gap between the other HiRISE images but where there is also CRISM coverage.

HiPOD 28 Dec 2022: Yardangs Forming near Gordii Dorsum
The purpose of this observation is to determine how these formations, called “yardangs” are forming within a layer of bedrock.
HiRISE resolution allows us to view yardangs and the component layers more closely, and to get a better understanding of the material.
HiRISE 3D: A Sand Filled Crater in the Medusae Fossae Region
This crater looks very interesting, especially in 3D.

HiPOD 27 Dec 2022: Two-Color Dunes in Meridiani Terra
Why are these dunes different colors? Sand on Mars is typically dark in tone, as it commonly derived from volcanic rocks like lava flows. In HiRISE enhanced color, which operates in long infrared wavelengths (beyond what the human eye can detect), surfaces like these dune crests are dark blue to purple.

HiRISE 3D: Mysterious Meander
This is a nice one: is it a past meander or has now (geologically speaking) been cut?

HiPOD 26 Dec 2022: What Gullies Can Say
Right past the sharp, but warped rim of this ancient impact crater are deposits of winter frost, which show up as blue in enhanced color.
There are two possible science goals that we can study here: what does the terrain look like during the Martian summer, because HiRISE resolution can track changes over time.

HiPOD 23 Dec 2022: Searching for RSL
A previous image showed recurring slope lineae (RSL) in multiple areas. The RSL are large and have high contrast. Most importantly, we see multiple examples of RSL flowing on bedrock, alternating between bedrock and regolith and regolith only. Do these candidate RSL fade? Do only the regolith RSL fade? Do they all lengthen?

HiRISE 10K: Dunes ’n’ Gullies
Two previous images at this site show dunes and gullies; this is a chance to reexamine both for changes. (See link for full 10K cutout.)
HiRISE 3D: Small Buttes and Dunes in Meridiani Planum
Our goal is to construct a digital terrain model for dunes detected to be active in earlier and later images.

HiPOD 22 Dec 2022: Fractured in Elysium
Researchers suspect this crater’s fractured floor is related to invasive lava, and it resembles weird tilted-facet terrain elsewhere on Mars. A stereo pair along some coverage of the lava outside the crater rim can help us determine how the elevations compare.

HiRISE 8K: Mantled Terrain in the Southern Mid-Latitudes
This HiRISE image shows terrain typical of these mantling deposits in the Southern Hemisphere, east of Reull Vallis. (See link for full 8K cutout.)
HiRISE 3D: An Athabasca Valles Distributary
A rationale that works for us: “Athabasca Valles overflow channel, worth a closer look.” Especially in 3D!

HiPOD 21 Dec 2022: Plates in Utopia Planitia
Plates in Utopia Planitia may be evidence of past fluid eruptions. A 2016 HiRISE image reveals portions of some plates, but these plates extend beyond the image where there is no current coverage. This observation is needed to help measure plate dimensions.

HiClip mini 4K: Elements of a Wasteland
A wide variety of south polar terrains are on display in this spectacular HiRISE color image. (This is a non-narrated clip with ambient sound.)
HiRISE 4K: Mineral Exposures in Terra Sabaea
This cutout features a portion of an impact crater with a curious shape, perhaps owing to epochs of erosion. (See link for full 4K cutout.)
HiRISE 3D: Mojave Crater North Rim
This is an area adjacent to fantastic earlier image, where tributaries extend up to drainage divides.
