HiPOD: Small and Beautiful

The objective of this observation is to examine gullies in an impact crater. Pictures like this one will help increase our inventory of Martian gullies, and perhaps lead to improved models. This scene is visible in CTX image P15_007045_1429. These gullies are quite small.

HiRISE 3D: A Candidate ExoMars Landing Site in Oxia Palus Region

While it may look flat and boring, our 3D images help science teams better to characterize potential landing sites for hazards.

HiPOD: The Dunes at the Center

This image was requested to capture as much of the dune field at the center of an impact crater as possible in order to investigate seasonal dune and frost monitoring.

HiPOD: Small Sinuous Ridges and Butte-Forming Material

Also visible in Context Camera data, in this observation are we seeing stream channels from the northwest wall of an impact crater that are now lithified and standing in relief becase of differential erosion? Or something else?

HIPOD: All We are is Dust in the Wind

The rationale for this requested target is short and sweet: “We are studying the fading of dust devil tracks in order to calculate the implied rate of dust deposition over their lifetime.”

HiRISE 3D: An Extra-Crater Sinuous Ridge

Identifying these types of fluvial ridges outside of craters is key for reconstructing ancient sedimentary basins, and channel deposits in basins are one of the key elements used to constrain ancient climate, water discharge, and base-level changes.

HiPOD: Mound Meets Flow

Also visible in Context Camera data, the objective of this observation is to examine how a lava flow is changed by a mound. Or perhaps it’s the other way around?

HiPOD: Revisiting InSight

InSight landed in a dusty area and eventually was coated in enough dust to make it difficult to discern in HiRISE images like this one. The landing itself also blew dust off a larger area and that dark surface marking has gradually been fading away with time too.

HiPOD: The Little Pit

This image was acquired to determine if any underlying void (open fracture or normal fault) and associated faults can be observed in this part of Arsia Mons. Pits may reflect geologically-recent tectonic or volcanic activity. Any associated caves could be targets for future robotic exploration. The pit is only a few meters across.

HiRISE 3D: Layered Deposits North of Jiji Crater

Layered deposits visible at Context Camera resolution in this location may be linked to more extensive deposits directly south within Jiji Crater.

HiPOD: Knobs and Valleys in Acidalia Planitia

This image features mounds and hummocky/fretted terrain of similar formation as those in far eastern Acidalia Planitia, but are not common on Mars, and may be the edge of an ancient basin. An additional rationale for this observation is to create a gigapixel mosaic of this area, which has received sparse coverage so far.

HiRISE 3D: An Outcrop in Athabasca Valles Lava

This image was taken to finish up stereo mosaic of this scaly outcrop (possible result of invasive lava). Parts of the outcrop are surrounded by what looks like an inflationary margin, but here it looks like some of the scaly blocks might be embedded within the flow. What was the sequence of events?

HiPOD: Mounds on the Floor of Kashira Crater

Light-toned mounds on the floor of Kashira Crater exhibit signature of aluminum-phyllosilicates or hydroxylated silica in CRISM multispectral data. Mars Orbiter Camera images show networks of ridges on the mound surfaces, possibly resistant fractures resulting from alteration or cementation by fluids. Some surfaces have a polygonal texture.

HiRISE 3D: Possible Scour Pits adjacent to Yardangs in Southwest Olympus Mons

These features are much smaller than usual scour pits. It has been hypothesized before that scour pits could be related to yardangs, but overall, scour pits and their relationship to the Medusae Fossae Formation are not well understood.

HiPOD: A Crater adjacent to Mawrth Vallis

What is striking about this observation are the very high thermal-infrared contrasts that should provide a good look at the stratigraphy of this clay-rich region. This mineral diversity here might be of interest as a site for future exploration.

HiRISE 3D: A Cluster of Mounds in Terra Cimmeria

This cluster of mounds exhibits low thermal inertia relative to surroundings. Are these (igneous/mud) volcanoes? Erosional remnants?
