HiPOD: Drainage Divide Migration in Tyrrhena Terra

A profiling method can determine the history of drainage migration in bedrock-erosion landscapes, but only with high-resolution terrain models as input. HiRISE stereo was requested as Context Camera digital terrain model resolution would likely not be adequate for this purpose.

HiRISE Epigrammata

“Now small fowls flew, screaming over the yet yawning gulf; a sullen white surf beat against its steep sides; then all collapsed, and the great shroud of the sea rolled on as it rolled five thousand years ago.”

—Herman Melville, “Moby Dick”

HiRISE 10K: A Bounty of Dark Dunes

The North Polar layered deposits (NPLD) are a stack of dusty water-ice layers that are thought to record information about past Martian climates.

HiRISE 3D: Rappeler’s Delight!

Scarps such as this have either active mass wasting or potential for current mass wasting. Comparison to previous years helps to document new activity in scarp erosion.

HiPOD: Eroded Sedimentary Rock Layers

The layered sedimentary rocks of Mars are of interest as indicators of ancient climate change. This scene was also captured in stereo so stereo anaglyphs are available to show the dramatic steep slopes of this eroded landscape.

HiRISE 8K: Streaks Emanating from Hale Crater

This image shows areas of bedrock (light areas) that appear to have been grooved or scoured in a uniform direction.

HiRISE 3D: Alluvial Fans in Southeastern Mojave Crater

Love, love, LUV Mojave Crater! Our objective is to characterize grain and topographic shape.

HiPOD: Fractures in West Candor Chasma

Our objective for this observation is change detection of youthful fractures observed in an image we acquired in 2007. Are these fractures active? These layers have been shifted along faults and also folded, giving the layers a wavy appearance as they are exposed at the surface through erosion.

HiRISE 4K: Chryse Planitia Surfaces

This image shows part of the surface of Chryse Planitia, near the mouth of several of the giant outflow channels carved by massive floods. At this location the channel is much too large to be seen within a HiRISE image, and this shows an area of level plains near the mouth.

HiRISE 3D Extra: High-Latitude Exposure of North Polar Layered Deposits

Stereo was requested for this location because MOLA data is very sparse here.

HiRISE 3D: A Simple Gullied Crater

This is a repeat image of a gullied crater for look for change detection, especially seasonal frost.

HiPOD: An Elongated Mound Northwest of Oxia Planum

This is a geomorphologically unique mound, with distinctive layering visible in Context Camera imagery. This HiRISE observation allows for better resolution of the layers, which may aid in our understanding of their mode of formation and depositional environment.

HiPOD: Sharp Mounds near Huygens Crater

The objective of this observation is to determine the nature of a group of sharp mounds. Most are angled and have straight sides. They only appear in one spot in a Context Camera image of the same area.

HiPOD: A Circular Feature Crosscut by a Lava Channel

This scene shows a circular feature about 3 kilometers in diameter with raised rims surrounded and infilled by lavas.

The circular formation is likely an eroded impact crater whose walls have been breached by the lava as it surrounded the rim and then infilled the crater. Alternatively, it could represent the location of a volcanic vent that sourced some of the lavas that formed the channel.

HiPOD: A Mound with a View

This image from the southern floor of Gale Crater shows narrow curvy ridges that connect to larger fan-shaped deposits. These narrow ridges were once the floor of a channel that are now standing in positive relief because the finer-grained material on the flanks of the channel has been blown away by the wind.

HiPOD: A Colorful New Crater

This image shows a small, colorful new crater near the equator of Mars, first detected by the Context Camera. The distinctive color of all of the ejecta shows that the surface material is different from the subsurface.

HiPOD: Volcanoes and Collapses

Volcanoes come with their own underground plumbing systems that move molten rock around and feed eruptions onto the surface. Sometimes these plumbing systems can drain causing collapses of the ground above them.

HiPOD: Debris from a Former Martian Glacier

Many mesas, hills, or mounds in the mid-latitudes of Mars show features extending from their walls that are called lobate debris aprons (LDAs). These LDA have been interpreted as debris-covered glaciers and have been shown by radar data to have nearly pure ice content beneath the meters-thick debris layer.
