HiRISE: Beautiful Mars (NASA)

HiRISE 3D: Fractured Material in Tooting Crater Fractures are theorized as a source of volatiles/groundwater supply to pitted materials immediately following deposition. Our goal is to look for evidence of groundwater release or aqueous weathering. uahirise.org/anaglyph/ESP_0… #Mars

HiPOD: In Iani Chaos The shape of this terrain is dominated by large-scale remnant massifs, which are large relief masses that have been moved and weathered as a block. Other images show there are light-toned deposits here amongst the chaos blocks. uahirise.org/hipod/ESP_0771… #Mars

HiPOD: Sedimentary Rock Layers in Terby Crater Sedimentary layers record a history of Mars’ erosion and deposition by water and wind, and they make great landscapes for future interplanetary parks. uahirise.org/hipod/ESP_0628… NASA/JPL-Caltech/University of Arizona #Mars #NASA

HiPOD: Dunes and Bedrock These sand dunes in a crater south of Mawrth Vallis are being monitored to measure changes. However, active dunes also clear the dust off of the bedrock between the dunes, which may have diverse colors and compositions. uahirise.org/hipod/ESP_0628… #Mars

HiRISE 10K: Stratigraphy of the North Polar Deposits This image shows an example of layers in the Martian North Polar deposits. These deposits are composed mainly of water ice and small amounts of dust. Full cutout on Flickr: flic.kr/p/2ssnadJ #Mars #NASA #science

HiPOD: Depressions in Deuteronilus Mensae The objective of this suggestion is to determine the nature of depressions, some of which have high, steep walls. Pictures like this one will help us determine how this material evolves over time. uahirise.org/hipod/ESP_0771… #Mars #NASA

HiRISE 8K: Reading the Rock Record at Nili Fossae This image captures a record of changing environments on ancient Mars, as recorded in the rock record at Nili Fossae. Full cutout on Flickr: flic.kr/p/2ssodVn NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiPOD: Mantling and Glacial Erosion This observation features a mantled impact crater with a good exposure of bedrock on the nothern part of the rim. Other areas of bedrock show signs of erosion. The central pit may also be possibly mantled. uahirise.org/hipod/ESP_0771… #Mars #NASA

HiRISE 4K: Russell Crater Sand Dunes Channels down the face of the largest dune show dark spots where the sublimation of the seasonal carbon dioxide ice cap has begun. Full cutout on Flickr: flic.kr/p/2ss1KXC NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiRISE 3D: Anaglyph Gullies Our science goal? To look for changes in the gullies, including possibly fresh deposits of material. uahirise.org/anaglyph/ESP_0… NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiPOD: Hydrated Sulfates in Columbus Crater From HiWish: “An area of mineralogic interest identified by CRISM, which lacks HiRISE coverage.” Sulfate-rich rock outcrops on Mars may be a good location to search for evidence of past life on the planet. uahirise.org/hipod/ESP_0771…

HiRISE 3D: Hale Crater Gullies The gullies are very deeply incised with extensive debris aprons. There are piles of material (boulders? snowpack?) that clog some of the gully channels. uahirise.org/anaglyph/ESP_0… NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiPOD: Periglacial Terrain in Protonilus Mensae With this observation, the existing periglacial mantle near a previous image can be better constrained across this area. Futher up from this pic, the terrain appears scoured and the mantle is discontinous. uahirise.org/hipod/ESP_0771…

HiRISE 3D: Layered Deposits of a Pollywog Crater A “pollywog” defines an exit breach possibly feeding candidate fluvial or lake sediments to a young crater at the equator. uahirise.org/anaglyph/ESP_0… NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiPOD: Avalanche Season Avalanches have been observed at this scarp, north of the another location with such activity. Monitoring this site is key to constrain the frequency of avalanches and timing of the onset of “avalanche season”. uahirise.org/hipod/ESP_0771… #Mars #NASA

HiPOD: In the Wake of Ancient Lava Flows Long ago, a large lava flow passed through the Athabasca Valles region of Mars. We can tell which direction it was flowing by examining the surface of the flow and the remaining “lava wakes.” uahirise.org/hipod/ESP_0753… #Mars #science #NASA

A newly found world blurs the boundary between planet and moon sciencenews.org/article/exopla…

HiPOD: Cliffs of Ice Sometimes a feature like a cliff cuts through the terrain and gives us a glimpse of buried icy material. The cliff in this image is one example out of a few dozen that are known. uahirise.org/hipod/ESP_0749… NASA/JPL-Caltech/University of Arizona #Mars

HiRISE 3D: Ice Margin This eerie-looking image shows us the icy margin of a lobe-shaped debris apron. What geological dynamics are at play here? uahirise.org/anaglyph/ESP_0… NASA/JPL-Caltech/University of Arizona #Mars #NASA #science
