HiPOD: Wonderful Gullies When we have an opportunity to image gullies, we’ll definitely do it! This observation is to re-image these very nice gullies for change detection, to get better topography and to look for possible fresh deposits. ID: ESP_065243_1410

HiPOD: Troughs and Ridges in Reull Vallis Our objective is to determine the nature of a group of ridges, troughs, and pits. They have a certain shape that repeats over and over, that may be affected by the change in the valley’s direction at this point. uahirise.org/hipod/ESP_07739…

HiPOD: In Search Of...Wind Streaks A key feature of wind streaks is their high rate of erosion. Dark wind streaks erode a few centimeters a year. The proposed area appears to be a dark wind streak and is rapidly changing. uahirise.org/hipod/ESP_07735… #Mars #NASA

HiPOD: Exposed on Mounds The objective of this observation is to examine layers exposed on mounds in a valley to the south of Nilosyrtis Mensae. Nilosyrtis is just to the east of Protonilus Mensae and both lie along the Martian dichotomy boundary. uahirise.org/hipod/ESP_06526…

HiPOD: Ancient Clays near the Hellas Basin Ancient clay-rich sediments (orangish color and polygonal fractures) exposed between wind-blown dunes and patches of sand northwest of the giant Hellas impact basin. uahirise.org/hipod/ESP_09316… NASA/JPL-Caltech/University of Arizona #Mars

HiPOD: Sourcing the Dark Sands of Nili Fossae Nili Fossae has been a favorite target of HiRISE since its arrival at Mars in 2006, for many reasons, including the dramatic shape of the giant trough network and its diverse geologic materials. uahirise.org/hipod/PSP_01012… #Mars #NASA

HiPOD: Light Layers, Dark Land The objective of this observation is to examine a light-toned layer that is at the base of a low mesa-like feature. This scene is to the north of Hadrica Patera, located to the northeast of the Hellas Planitia impact basin. uahirise.org/hipod/ESP_07738…

HiPOD: A Canyon Wall in Coprates Chasma The walls here potentially expose pristine crustal material. This is an area of interest that could be accessed and is within potential future rotorcraft mission traverse. uahirise.org/hipod/ESP_07735… NASA/JPL-Caltech/University of Arizona

HiPOD: Layers in Nili Fossae These beautiful false color cutouts feature a series of layers in Nili Fossae. Nili has often been on the list for potential landing sites for robotic exploration, given its rich landscape of mineral diversity. uahirise.org/hipod/ESP_07736… #Mars #science

HiPOD: Mounds and Pits The objective of this observation is to determine the nature of a group of mounds, some of which have small pits at their summits. These features may be caused by ground ice melting and possibly turning into steam. uahirise.org/hipod/ESP_06966…

HiPOD: A Ridge in Arabia Terra The objective of this observation is to examine a straight ridge that might be a dike. Sometimes magma (molten rock) below the surface may fill an existing fracture, even pushing the fracture open in the process. uahirise.org/hipod/ESP_06530… #Mars

HiRISE 3D: A Small Channel The objective of this observation is to examine a small channel on the wall of an old impact crater. The scene is also visible in Context Camera image data. uahirise.org/anaglyph/ESP_09… NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiRISE 3D: Quite Lovely Bedrock in Aureum Chaos Imaging this part of Mars is always a delight with the stunning chaotic terrain and bright exposures of bedrock against darker surroundings. uahirise.org/anaglyph/ESP_09… NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiPOD: Cutting through Lava Flows on Olympus Mons There appears a single deep channel that is cutting through a field of lava flows on the eastern flank of Olympus Mons. More: uahirise.org/hipod/ESP_06525… NASA/JPL-Caltech/University of Arizona #Mars #science #NASA

HiRISE 3D: Beautiful Jezero This is the third of 6 stereo pairs requested for building an SRL EDL system reference map for Mars Sample Return. And it looks stunning. uahirise.org/anaglyph/ESP_09… NASA/JPL-Caltech/University of Arizona #Mars #NASA #science

HiPOD: Crommelin Dunes This is one of many observations we acquire to aid in the classification of dunes in the USGS global dune database. Studying dunes is useful because they are abundant over a wide range of elevations and terrain types. uahirise.org/hipod/ESP_07734… #Mars

HiRISE 3D: Irregular Structures The aim of this image is to provide high-resolution data of cell-shaped structures on the surface of a debris-covered glacier to investigate if they are linked to an interaction between the ejecta and the ice. uahirise.org/anaglyph/ESP_09… #Mars #NASA

HiPOD: Streamlined Landforms These streamlined landforms adjacent to Shalbatana Vallis show multiple levels of fluvial dissection. An outflow channel carved by massive floods of escaping groundwater, Shalbatana Vallis is over 1300 km long (808 miles). uahirise.org/hipod/ESP_07733…
