| A Layered Butte East of Tinjar Valles
The objective of this observation is to determine the nature of a layered butte that is surrounded by concentric fractures. A collapse feature? The scene is also visible in Context Camera image data. |
| Not Wizard and Glass, but Dunes and Gullies
Two previous images at this site show dunes and gullies; this observation provides a chance to reexamine both for changes. Dunes have slip face striations suggesting recent sand avalanches. The gullies are not especially well-developed, but worth another look. | 
| A Mesa in Southern Utopia Planitia
The “collarlike” shapes we see in this observation may indicate the deflation of old flow units. Since Utopia Planitia is a volcanic region of Mars, perhaps the units could have formed when volcanic material cooled and then contracted. With a stereo pair, we can investigate if the collar is at a constant elevation. | 
| Layers at the Edge of a Pedestal Crater
The objective of this observation is to examine rock layers along the edge of a mesa that was created from a pedestal crater. This image will help us establish the horizontal distribution of layers in the Arabia region of Mars, and is also visible in Context Camera data. This scene is located within the much larger (344 kilometers, or 214 miles) Tikhonravov Crater. | 
| The Possibilities of Pyroxene
This observation request is based on a strong parameter signature of pyroxene coming from the latest CRISM multispectral survey data release. Context Camera data also shows light-tined materials here, and to date, there is no HiRISE coverage. Pyroxenes are particularly widespread in the cratered highlands, pointing to some of the most ancient portions of the planet’s crust. |
