HiRISE 3D: Light-Toned Deposits in Iani Chaos Context Camera images show there are light-toned deposits here amongst the chaos blocks. Full image: https://t.co/SBjoTVcCvw NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiPOD: A Dune Field of Mars The science goal of our observation is checking to see if (1) dune alcoves are forming; (2) if autumn or winter frost is forming that can help to investigate a connection between them. https://t.co/qDXnrsKjAE NASA/JPL-Caltech/University of Arizona

HiPOD: Frosty Alcoves on Kaiser Crater Dunes Kaiser Crater hosts a large field of sand dunes. Every winter the dunes are covered with a layer of seasonal carbon dioxide ice (dry ice). In early spring the ice begins to sublimate. More: https://t.co/n5quZUBoiN #Mars #science

HiRISE 3D: Celebdil, Caradhras and Fanuidhol Sorry, these are not the three mountains of Moria, but rather three impressive peaks in the southern part of the much larger Antoniadi Crater on Mars. https://t.co/BqpwcjMkWP NASA/JPL-Caltech/University of Arizona #Mars #NASA

HiPOD: Alluvial Fans in Mojave Crater The landscape in this observation is pervasively eroded, right up to the tops of the ridges, with channels extending down into depositional fans much like alluvial fans in the Mojave Desert. https://t.co/x3Fp0YK0RN #Mars #NASA #science

HiPOD: Ridges in Isidis The objective of this observation is to study the transition area where the density of pitted cones changes significantly. Isidis Planitia is an impact basin where volcanic and fluvial/glacial landforms are abundant. https://t.co/sNqp5hbeR7 #Mars

HiRISE 3D: The Remnant Fan In this observation, a jagged surface protrudes outward from a prominent scarp and associated spur and gully features. This is a candidate remnant fan that likely eroded during a mega flood event. https://t.co/Zx9677RgGE #Mars #NASA #science

HiPOD: Layers of an Impact Crater The objective of this observation is to examine layers in the eroded north wall of a crater. All along this wall, there appear to be layers. The layers can give us an idea of at what depth they formed. https://t.co/9lzGPF90nS #Mars #NASA

HiRISE 3D: Lovely Jezero This image is part of a series of stereo pairs in Jezero Crater requested for building an SRL EDL system reference map for Mars Sample Return. https://t.co/rXdX9P1Hbq NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiPOD: Low Latitude Channels The objective of this observation is to examine channels. Some are rather deep, but others that are eroded are small branches. https://t.co/Vx1q8gt9OK NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiRISE 3D: Layering in Lucus Planum This image shows extensive layering a southern part of the Medusa Fossae Formation. Layer thickness and orientation may indicate internal structure of the MFF. https://t.co/IEdTSb80UT NASA/JPL-Caltech/University of Arizona #Mars #NASA

HiPOD: Fissure Elegance Our science objective here is straightfoward: to investigate this interesting fissure geometry and the sourcing channels. This flat, volcanic plain is located directly east of Pavonis Mons. https://t.co/8bhuGV2PJ3 NASA/JPL-Caltech/University of Arizona

HiRISE 3D: Chryse Chaos Our science objective is to document stratigraphic relationships between chaos blocks and adjacent geologic units. https://t.co/fwu9Ugx1XZ NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiPOD: Once in Melas This stunning observation shows part of the western end of a basin within Melas Chasma: a series of interstratified valleys and inverted channels. https://t.co/jR4IR3Fh2C NASA/JPL-Caltech/University of Arizona #Mars #science #NASA

HiPOD: Springtime on a Polar Cliff In this image we can see many dark streaks extending down the slope, but no sign yet of larger avalanches that were common in past years. https://t.co/SUmId7V0X8 NASA/JPL-Caltech/University of Arizona #Mars #science #NASA

HiPOD: Ice-Rich Terrain of the Northern Plains This image shows a surface shaped by ice. Funnel-shaped craters scattered throughout the image are interpreted as impacts that once had the classic bowl shape, but have now expanded via sublimation. https://t.co/p2GcPlBYV3 #Mars

HiPOD: Layers in Hydraotes Chaos Also visible in Context Camera data, the objective of this observation is to examine layers in Hydraotes Chaos.Hydraotes is what geologists label as “chaotic terrain.” https://t.co/hbM9jIPLQQ NASA/JPL-Caltech/University of Arizona #Mars

HiRISE 8K: The Vastness of the Dunes This impressive observation is near the North Pole of Mars, in a region known as Vastitas Borealis. Full cutout on Flickr: https://t.co/ddnrWt4fZr NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiPOD: Layering in Arabia Terra Arabia Terra never fails to amaze: this observation shows exquisite layering that offers us a chance to measure the bed thickness of these layers. https://t.co/qvrRnm6p3C NASA/JPL-Caltech/University of Arizona #Mars #science #NASA
