| Mounds in Northwest Argyre Planitia
This observation focuses on aligned mounds on the Argyre basin floor near a lobate contact. A possibly deflating icy surface with the underlying unit that itself might be an extrusive volcanic deposit. The mounds could be pseudocraters or tumuli, which are small, dome-shaped or elliptical features. The region name stems from the Greek word “argyros” (silver) and Argyre was an “island of silver” in Greek and Roman mythology. |
| Knobs in East Candor Chasma
This image footprint features an interesting area of Candor Chasma. There is possible soft sediment deformation of lacustrine (lake-related) sediment. Our image resolution, along with digital terrain model, can support geologic mapping. Candor Chasma is one of the largest canyons that make up Valles Marineris. It is approximately 810 kilometers long (503 miles). | 
| Sine of the Times
At the southern section of the floor of an impact crater is this stunning lobate (tongue-shaped) debris apron with surface banding showing high sinuosity. This is might be the result of glacial or periglacial processes at work in this and possibly other parts of the crater. | 
| The Lava Meets the Hills
What fraction of flows in this region had rootless cones? Studying this might tell us something about the history of ice in this part of Elysium Planitia. Another of our science goals is to examine samples of various flow margins where the lava was thin. Elysium Planitia is a flat-smooth plain just north of the equator that makes for the perfect location from which to study the deep Martian interior, such as with the InSight lander mission. | 
| The Awesome Layers of Hebes Chasma
A Mars Orbiter Camera shows good exposures of varied materials at this site, but our HiRISE observation can improve on the resolution to see fine scale details in the bedding. The layers appear to have varied albedo and regions free of dust. We want to look for variations and indications of composition. |
