HiRISE 4K: Layering along West Ganges Chasma
This observation shows a sequence of layered sedimentary rocks exposed along the wall of Ganges Chasma. Full cutout on Flickr: https://flic.kr/p/2psSanQ
HiRISE 3D: A Crater in Arabia Terra
This anaglyph shows the western side of an impact crater that has an exit breach on the opposite side.

HiPOD: Starfish & (No) Coffee
Our science goal with this observation is to assess winds from these seasonal fans in a lightly imaged longitude region informally dubbed “starfish”. The dark fans are the result of sublimation. The area also has a long monitoring history for these types of small-scale changes. (The title is a reference to a song. Can you guess the artist?)

HiClip mini 4K: Once Upon a Martian Lake
Terra Sirenum is a large area of Mars in the Southern Hemisphere and is believed to have once held a lake. (This is a non-narrated clip with ambient sound.)
HiRISE 3D: A Cliff in Milankovic Crater
This scarp is very probably an icy one, so we can also look for changes.

HiPOD: Erosional Features on Olympus Mons
In Context Camera data, we see scour pits in the northern part of Olympus Mons. This cluster of erosional features is isolated from the main Medusae Fossae Formation (MFF) units. All other scour pits are found within the MFF, so high resolution imaging here could give us insight into what causes the scour pits to form and what the MFF is made out of.

HiRISE 3D: Aram Chaos
This anaglyph will help to document the stratigraphic relationships between chaos blocks and adjacent geologic units.

HiPOD: A Pit near Arsia Mons
Also in Context Camera data, this image can help to determine if any underlying void (open fracture, dilational normal fault) and associated faults can be observed. Pits may reflect geologically recent tectonic or volcanic activity. Any associated caves could be targets for future robotic exploration.

HiPOD: Fans and Valleys
Thick beds with varying tone are exposed along the edge of the fan. Shallow valleys that carve into the smooth upland surfaces outside of the crater may provide clues regarding the formation of the deposits.

HiRISE 3D: Raised in Athabasca
This observation shows part of a high-standing mesa in an ancient lava field.

HiPOD: Dune Avalanche Slopes
These dunes have exhibited recurring slope lineae (RSL)-like streaks in a couple of previous images, but they do not seem to have been significant in 2013, when we obtained a full monitoring series. With this observation, we can keep monitoring to understand this activity, which may help test the RSL-granular flow model for the streaks.

HiRISE 8K: Bright Streaks and Dark Fans
The conditions must be just right for the bright frost to condense.

HiRISE 3D: Like a Big Pizza Pie…
Only this one is seen from the Mars sky! This image shows a pie-like feature which is hypothesized to be the result of subsurface sediment mobilization.

HiPOD: Terrain in Hebes Chasma
Hebes Chasma is an isolated depression to the north of Valles Marineris, with no outflow channels. Some material on the walls of the chasma is different from the central mesa. We obtained this observation to investigate a possible landslide within the stratified sediments from one of the chasma’s walls.

HiPOD: A Clay-Rich Mound in an Eroded Plateau
These mounds contain bright-toned material which have been found to be clay-bearing with data from the CRISM instrument on MRO. This particular example contains both aluminum and iron/magnesium bearing clays. These regions of bright-toned material are layered down to the meter scale and are heavily fractured, reminiscent of the clay-bearing deposits at Mawrth Vallis.
