Rare evidence for fault reactivation

Rare evidence for fault reactivation
Rare evidence for fault reactivation Opportunity took this image on Sol 1784 more than 3200 sols or Martian days ago with her Navigation Camera (Navcam). It shows a fracture that apparently reactivated recently enough to offset a large wind ripple, leaving the two sides misaligned. "Displacement fault activation does occur, very rarely,” Sullivan concluded. NASA / JPL-Caltech
