This image in Ius Chasma, a portion of the massive canyon system Vallis Marineris, draws our attention because a fault previously imaged by the Mars Orbiter Camera.

A valley also cuts across the ridge. Is this the result of some tectonic process? A study in 2012 suggested that Mars possesses tectonic plates, but if so, how these processes work is still an area of study.

This caption is based on the original science rationale.
