HiPOD: The Inner-Channel Problem

Not so much a problem but an hypothesis: Context Camera data suggests an inner-channel in this long valley system. HiRISE is needed to check and enable measurement of channel width. Inner channels are useful for paleohydrology, but they are rarely preserved in long valley systems.

HiRISE 3D: Deltaic Lobes in Aeolis Dorsa

Observations like these may suggest that Aeolis Dorsa is a paleo-coastal region which may be an important site for exploration in the future.

HiPOD: Channels in Enipeus Vallis

The objective of this observation is to examine small channels. They may be caused by lava or water, as there are many lava flows here. Enipeus Vallis is a valley in the Northern Hemisphere of Mars, following a North-South path for about 357 km (222 mi). Enipeus is a river god in Greek mythology.

HiPOD: Clay-Rich Terrain in Northeast Syrtis Major

This observation was requested because of an interesting mineral outcrop identified in CRISM mapping data. It is likely an iron/magnesium phyllosilicate (clay). Syrtis spans some 1,300 km (800 mi) wide, yet rises only about 1 km (3,300 ft) high and is one of the most prominent Hesperian volcanic complexes on Mars.

HiPOD: Light-Toned Mounds in Gorgonum Basin

Gorgonum Basin is one of several large basins within the Terra Sirenum region of Mars. Each basin has light-toned mounds, many of which contain clays.

Scientists think that Terra Sirenum once had a large lake during an epoch called the Late Noachian/Early Hesperian, and each basin filled with sediments. The water within the lake may have altered these sediments to form the clays we now observe from orbit.

HiRISE 3D: Exposure of South Polar Layered Deposits

The existing topographic data here is sparse here, so this adds to our knowledge inventory.

HiPOD: A Channel on a Crater Wall

The objective of this observation is to examine a small channel on an old crater wall. The channel has cut through the rim in two places, and this scene, located north of the Hellas region, is also visible in Context Camera data.

HiRISE 3D: Light-Toned Deposits in an Impact Crater

This crater is located to the north of Eberswalde Crater, and the image was requested to resolve layering here.

HiPOD: Lithified Lobes

This observation features a possibly multi-layered lobe that might be ejecta from craters on southwest rim of the crater in which they occur. They could also be landslide deposits that pre-date those impacts, meaning that the ejecta had to have eroded away before re-exposing landslide lobes. Either way, the erosional expression is suggestive that the materials are perhaps lithified.

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.

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: 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.
