Unusual Crater with Lava Flows near Arsia Mons
ESP_017347_1585  Science Theme: Volcanic Processes
This image was targeted to look at lava flows in east Daedalia Planum. The flows here have different brightnesses (reflectivity) which may indicate different compositions.

The cutout shows another aspect of the image. A small, 0.5 kilometer diameter crater shows a regular structure of aligned ridges in its interior. The origin of this structure is unclear but may be related to the breach in the crater rim to the left.
