HiPOD: Dunes in Hellas Scientists on the HiRISE team take multiple pictures of the same dune fields on the Red Planet to see if they can detect subtle changes that would indicate if the dunes are moving. More: uahirise.org/ESP_075654_1385 NASA/JPL-Caltech/University of Arizona

HiRISE 3D: Next to the Debris Apron Today’s HiPOD also doubles as our 3D image of the day, as it was too good to resist. Here, a lower-lying channel is adjacent to a part of a large debris apron. uahirise.org/anaglyph/ESP_09… NASA/JPL-Caltech/University of Arizona #Mars #NASA

HiPOD: Channel, Meet Debris Apron This feature may represent evidence of meltwater originating downstream from a lobe-shaped debris apron. Our HiRISE image will provide more details of the contact between the channel and the debris apron. uahirise.org/hipod/ESP_09222… #Mars #science

HiPOD: Ejecta as Art This image footprint is part of the massive ejecta blanket of Arandas Crater. The inner ejecta layer runs up against the rim of a pre-existing crater, and has produced several compressional ridges on the blanket. uahirise.org/hipod/ESP_07706… #Mars #science #NASA

A Rare Meteorite Just Revealed a Lost, Mars-Sized Planet from the Dawn of the Solar System

Meteorites are (usually) gifts from the heavens. They provide unique insights to parts of the solar system that we couldn’t access otherwise - either because it's too expensive, or because the solar...

NASA declares MAVEN, its Mars atmosphere orbiter, dead

Over more than a decade at Mars, the orbiter revealed how the solar wind strips away the planet’s atmosphere — and why the world lost its water.

HiPOD: The Tale of a Retreating Scarp This scene on the north rim of Secchi Crater shows a curious depression with zig-zag walls. Some of the linear ridges on the floor of this feature are aligned with them. More: uahirise.org/hipod/ESP_07523… NASA/JPL-Caltech/University of Arizona

HiPOD: Landforms in Utopia Planitia This observation features landforms that resemble cratered-cones, but may have a different formation mechanism. With HiRISE, we can look for textures that may provide clues on how these features formed. uahirise.org/hipod/ESP_07706…

HiPOD: The Floor of East Candor Chasma This target location is an interesting area, with possible soft sediment deformation of lacustrine (lake-based) sediment. This observation was requested to support geologic mapping. uahirise.org/hipod/ESP_07705… #Mars

HiRISE 3D: Gorgeous Gullies Give your eyes an extra second to adjust and take the full of these well-defined gullies on a steep crater wall. The floor of the crater appears relatively flat, perhaps some glacial processes were once at work here. uahirise.org/anaglyph/ESP_09… #Mars
3D image shows a steep impact crater rim with numerous, well-defined gullies extending from near the top down to the flatter bottom of the crater.

The Scalloped Terrain of Utopia Planitia This image footprint is in a region of abundant scalloped depressions. Their formation most likely involves development of oval- to scalloped-shaped depressions that may coalesce together. uahirise.org/hipod/ESP_07703… #Mars #science #NASA

HiRISE 3D: A Wonderously Weird Dune Field This stunning image is part of a campaign to aid in classification and volume estimates of dunes not mapped in the USGS global dune database of Mars. uahirise.org/anaglyph/ESP_09… NASA/JPL-Caltech/University of Arizona #Mars #NASA #science
3D image shows a wide, aerial view of a dune field on Mars. The dunes are elongated and appear like long tubes, separated by flatter, rocky terrain.

HiPOD: Fluvial Erosion in Phlegra Montes This public target via HiWish suggests to observe possible fluvial erosion that could help understand the climate history of Mars. Context Camera data and previous HiRISE images show faint, but possible channels. uahirise.org/hipod/ESP_07682…

HiRISE 3D: A Small Fresh Crater in Syrtis Major Planum The ejecta from the impact is still dark and highly visible, so the crater is likely geologically recent, although we have no previous image to help us constrain when it might have formed. uahirise.org/anaglyph/ESP_09… #Mars
3D image shows a small impact crater on the surface of Mars. There are dark rays around the crater, called ejecta, that formed when the impact occurred, and have not faded so far.

HiPOD: A Pit near Arsia Mons Previously visible in Context Camera data, our image can determine if any underlying void and associated faults can be observed. Pits may reflect geologically-recent tectonic or volcanic activity. uahirise.org/hipod/ESP_07679… #Mars #NASA #science
Enhanced color cutout shows a small pit on the surface of Mars. The bottom of the pit is visible, but it could also be a small cave.

HiPOD: Layers in West Melas Chasma This stunning image shows well-exposed layers of a canyon wall in Melas Chasma. Our science goal is to see if we can constrain layer orientations and unconformities. uahirise.org/hipod/ESP_07704… NASA/JPL-Caltech/University of Arizona #Mars #NASA
Enhanced color cutout shows a detailed aerial view of extensive bedrock layers on the wall of a canyon on Mars. The layers are not all straight and appear to curve at certain points in the image.
