HiRISE 3D: Possible Ice-Related Features in an Argyre Region Crater

The science rationale was to look at stratigraphic relationships between (1) gullies, (2) latitude-dependent mantling, (3) arcuate ridges, and (4) concentric ridges on the crater floor.

HiPOD 2 Oct 23: Along Samara Valles

This image was requested to look for the source of late discharge along Samara Valles. It appears to emerge from a tributary to the west or further south in convoluted materials. Samara Valles are an elongated set of channels extending 615 kilometers long and were named after the ancient Roman name for modern Somme River, France, in 1976.

HiRISE 10K: Of Dome and Crater

The objective of this observation is to take a look at a dome and adjacent crater also visible in Mars Orbiter Camera images. Did the mound form before the crater, or was it the other way around?

HiPOD 29 Sept 23: Channels on Edge

Also visible in Context Camera data, the objective of this observation is to examine channels on the outside northern edge of a crater. They may have resulted from the heat of impact. The scene itself is located to the east of Huygens Crater.

HiRISE 8K: A Transition Boundary

The rationale for this target was to acquire high-resolution detail of the contacts of the transition boundary between the Libya Montes and Isidis Planitia.

HiRISE 3D: Depressions at the Margin of Gigas Sulci

A sulcus (or sulci, plural) is defined as “subparallel furrows and ridges.” This is a purely descriptive term for landforms that could have a variety of origins.

HiPOD 28 Sept 23: Spiders on the One, Polygons on the Other

Not actual spiders, of course, but formations often caused by sublimation of subsurface ice that create spider-like patterns. This image was acquired to study the influence of exposure to the sun’s rays on spider versus polygon development in terrain like this.

HiPOD 27 Sept 23: An Extra-Crater Sinuous Ridge

Identifying these types of fluvial ridges outside of craters is critical for reconstructing ancient sedimentary basins, and channel deposits in basins are one of the key deposits used to constrain ancient climate, water discharge, and base-level changes. This is a previously unidentified sinuous ridge from a recent global survey of such features.

HiPOD 26 Sept 23: Radial Ridges on a Crater Floor

The objective of this observation is to determine the nature of a group of short radial ridges on an old crater floor. These may be inverted channels from previous glaciers in the crater. The scene can be found in Context Camera data.

HiPOD 25 Sept 23: A Fan in a Low Latitude Crater

The objective of this observation is to examine a possible fan along the wall of an impact crater. Ridges coming from a valley on the wall may be inverted terrain. The crater floor contains a depression that displays layers; hence, there may have been a lake in the crater.

TOUCHDOWN! The #OSIRISREx sample capsule landed at the Utah Test and Training Range at 10:52am ET (1452 UTC) after a 3.86-billion mile journey. This marks the US's first sample return mission of its kind and will open a time capsule to the beginnings of our solar system.

HiPOD 23 Sept 23: A Layered Mound in Juventae Chasma

The light-toned mounds, like this one in Juventae Chasma, generally contain sulfates, which are salts of sulfuric acid that form when water is evaporating.

The darker material that we see is collecting near the base of the light-toned mound, and likely represents wind-blown debris.
