Craters and Landslides
ESP_022205_1625  Science Theme: Mass Wasting Processes
This observation shows a small crater on the rim of a larger crater that appears to have triggered multiple landslides at the time of impact. This also appeared in a Context Camera image (B22_018302_1621_XN_17S270W_100622).

This HiRISE image views the morphology of these landslides at higher resolution, covering the eastern portion of the landslides. Another observation of this area covering the western portion could show us the heads of the landslides.

Because the view of HiRISE covers less area than the CTX Camera, in this example, all HiRISE sees is part of one of the landslide lobes.

This caption is based on the original science rationale.
