| Layers in Rayleigh Crater
The objective of this observation is to determine the nature of layers in a mound in Rayleigh Crater. The layers may be mantle layers and with high resolution, the differences in those layers may give us insight concerning past climates. Rayleigh is approximately 149 kilometers in diameter and is located in the South Polar region of Mars. |
| Layered Blocks Leaning against Slopes
The objective of this observation is to determine the nature of layered blocks that lean against slopes in this area of Deuteronilus Mensae. They bear a resemblance to flatirons, like in America’s Southwest. These features have light and dark toned layers. HiRISE may be able to discover the reason for the tone difference; it may just be due to a difference in roughness. | 
| Possible Rock Falls in Cerberus Fossae
Our science goal is to obtain an image in order to identify fresh rockfalls that could be associated with seismic events/Marsquakes that might have been detected at some point by the InSight lander. The blue in our picture is likely basaltic (volcanic) in origin, not water. | 
| Flow Features
This location is optimal for active glacial flow because of the low crater density and steep slopes. As HiRISE has continued successful operation, now is the time to check for glacial flow on decadal timescales. Directly detecting glacial flow on Mars would be a big deal, in part because it would help determine how materials deform and flow when subjected to stress or force of the ice. | 
| Winding about in Nirgal Vallis
Nirgal Vallis is one of the largest and longest valley networks on Mars, approximately 400 kilometers in length. Although Nirgal formed long ago, likely by flowing water, abundant wind-blown sediments transformed into the dune fields that now line the valley floors. |
