HiRISE 3D: Small and Recent Craters here are distinctive in day and night infrared, relatively abundant over this area: are these primaries or secondaries? We can look for directional indicators. https://www.uahirise.org/anaglyph/ESP_092211_1630_ESP_092936_1630_RED #Mars #NASA #science

HiPOD: Deposits and Flows We are observing how surface flow patterns in the area vary with distance from the proposed parent crater. This is one of several flow feature observations being suggested in the vicinity of the crater to the east of here. https://uahirise.org/hipod/ESP_077165_1440

HiRISE 3D: Of a Crater Compared to the other ones in this image, this crater is geologically fresh, as we can still see the dark ejecta from the impact that hasn’t faded yet. https://www.uahirise.org/anaglyph/ESP_085139_1480_ESP_092958_1480_RED NASA/JPL-Caltech/University of Arizona #Mars #NASA

HiPOD: The Layered Mesa The objective of this observation is to examine a layered mesa within a small impact crater. The layers are horizontal and well-defined. These features are fairly common in this region of the Martian northern plains. https://uahirise.org/hipod/ESP_077117_2195 #Mars #NASA

HiRISE 3D: Martian Erebor? This footprint is also visible in Context Camera data, but HiRISE can view these interesting lobes in higher resolution. (“Erebor” is the name of the Lonely Mountain in JRR Tolkien’s Middle Earth.) https://www.uahirise.org/anaglyph/ESP_084819_1045_ESP_093007_1045_RED

HiRISE 3D: Mesas of Layered Sedimentary Rocks This anaglyph features a small, light-toned layered mesa near the Coprates/Melas junction. We can take a look at higher res to improve on MOC imaging and look for finer layering. https://www.uahirise.org/anaglyph/ESP_092088_1695_ESP_092523_1695_RED

HiPOD: A Channel and Crater in Terra Sirenum The objective of this observation is to examine a channel that eroded through both sides of a small impact crater. The channel seems to be in the middle of a larger valley. https://uahirise.org/hipod/ESP_077138_1415 #Mars #NASA #science

HiPOD: Colorful Rocks Exposed in a Fresh Impact Crater Rocks of several different colors are exposed in this crater’s walls; they are undergoing erosion into finer-grained debris that travels downwards and accumulates in small fans on the crater floor. https://uahirise.org/hipod/ESP_074332_1580

HiPOD: Piles of Sand with Different Sizes and Colors This image shows a variety of wind-related features near the center of Gamboa Crater. Larger sand dunes form sinuous crests and individual domes. More: https://uahirise.org/hipod/ESP_073613_2210 NASA/JPL-Caltech/University of Arizona #Mars #NASA

HiRISE 3D: Dark Linear Ridges in the Southern Highlands This 3D image features linear ridges, possibly transverse aeolian ridges or megaripples. Imaging will provide better measurements of ripples. https://www.uahirise.org/anaglyph/ESP_092756_1130_ESP_091978_1130_RED #Mars #NASA

HiPOD: Circular Mystery This image features an interesting circular outcrop of rock that appears dark in infrared but in Context Camera data, appears to be a much rougher terrain surrounding a knob. The remnant of an ancient cinder cone? https://uahirise.org/hipod/ESP_077125_1525 #Mars #NASA

HiRISE 3D: Hillslope Shapes near Eberswalde Crater Sediment-covered hillslopes are sensitive markers of the local climate and hydrology during their formation. Full image: https://www.uahirise.org/anaglyph/ESP_092812_1550_ESP_092601_1550_RED NASA/JPL-Caltech/University of Arizona #Mars #NASA

HiPOD: The Richness of Layers This stunning image features dozens of layers in the walls of a graben on the flanks of Arsia Mons. These layers could be lavas or ash deposits and their study can help to understand the history of this volcanic terrain. https://uahirise.org/hipod/ESP_077124_1725

HiPOD: Frosted Dunes in the Depths of Winter This picture was taken far north of the equator after the winter solstice when the Sun was just a few degrees above the horizon. Sand dunes are moving across this landscape from left to bottom. https://uahirise.org/hipod/ESP_074942_2295 #Mars #NASA

HiPOD: The Ever-Changing Swiss Cheese of Mars HiRISE monitors many areas of the cap to study these changes. When we study changes, we align the images with features that haven’t changed, but here, nearly everything is different! https://uahirise.org/hipod/ESP_074829_0945 #Mars #science #NASA
