| A Fissure Meets Channels near Olympica Fossae
This channel’s shape changes where a narrow fissure crosscuts the floor of a wider channel and adjacent surfaces. The fissure may have released fluid that formed or modified channels downstream to the south. Olympica Fossae is a complex channel located on the volcanic plains between Alba Mons and Olympus Mons. |
| Layers within the Medusae Fossae Formation
Nearby observations show nice fine layering within the upper part of this region of the Medusa Fossae Formation (MFF). It looks like the layering may actually be quite continuous laterally. The MFF is an extensive unit of enigmatic origin found near the Martian highland-lowland dichotomy boundary between the Tharsis and Elysium centers of volcanic activity. | 
| A Light-Toned Deposit in Arsinoes Chaos
The objective of this observation is to examine a light-toned deposit in a region of chaos terrain. The deposit displays a rough surface, in contrast to the smoothness of the surounding area. Some parts of the surface appear as if they were eroded by a fluid flowing north and south. This deposit may have formed in an ancient lake. | 
| An Olivine-Rich Massif in Hellas
This observation targets banded terrain located in an olivine-rich massif in the Hellas Basin. The olivine-rich massifs have been interpreted as ejecta blocks excavated from the lower crust/upper mantle by the Hellas Basin impact. In places, this banding is disrupted by a blobby and streaky dark-toned unit. | 
| A Song of Ice and More Ice
This stunning image shows part of the South Polar residual ice cap, a term that refers to ice that lingers well past a seasonal change. Our science goal here is to look for any changes in the ice cap that might have occurred from a previous observation, although the changes might be small. |
