Subsurface Sediment Mobilization On Mars
[NASA/JPL/UA] This image covers a pie-like feature that thought to be the result of subsurface sediment mobilization.
![View of the Hindsight application: drive panel synchronization (A) ensures consistent arrangement of data sources. The playhead (B) is accessible across the drive panel, tying all visualizations to the same timestamp. The fault in question is highlighted across data in red via the fault overlay (C). -- [cs.HC]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Hindsight.png?resize=1200%2C723&ssl=1)
