| A Channel and Crater in Terra Sirenum
The objective of this observation is to examine a channel that eroded through both sides of a small impact crater. The channel seems to be in the middle of a larger valley. Terra Sirenum is a vast, heavily cratered upland region in Mars’ Southern Hemisphere, stretching roughly 3,900 kilometers across. |
| Split Ridge, Small Crater
Also visible in Context Camera image data, the objective of this observation is to determine the nature of a relatively large split ridge in a small impact crater. The footprint of this observation is in Terra Cimmeria, a vast, densely cratered highland region in the Southern Hemisphere of Mars, stretching approximately 5,400 kilometers (3,400 miles) at its broadest extent. | 
| The Layered Mesa
The objective of this observation is to examine a layered mesa within a small impact crater. The layers are horizontal, and well-defined. These features are fairly common in this region of the Martian Northern plains, while these layers are more distinct than many others. | 
| Deposits and Flows in Terra Sirenum
With this image, we are observing how surface flow patterns in the area vary with distance from the proposed parent crater. This is one of several flow feature observations being suggested in the vicinity of the well-preserved crater to the east of this footprint, which itself at the northwestern edge of larger, in-filled crater. | 
| A Crop of Gullies
The objective of this observation is to examine large gullies within an impact crater in Terra Cimmeria. There are not too many large gullies in this area, but this crater has many of them. We may want to study why there are so many here at this location. This scene is also visible in Context Camera data. |
