As NASA's Mars Exploration Rover Opportunity continues a southward trek from "Erebus Crater" toward "Victoria Crater," the terrain consists of large sand ripples and patches of flat-lying rock outcrops, as shown in this image. Whenever possible, rover planners keep Opportunity on the "pavement" for best mobility.

This false-color image mosaic was assembled using images acquired by the panoramic camera on Opportunity's 784th sol (April 8, 2006) at about 11:45 a.m. local solar time. The camera used its 753-nanometer, 535-nanometer and 432-nanometer filters. This view shows a portion of the outcrop named "Bosque," including rover wheel tracks, fractured and finely-layered outcrop rocks and smaller, dark cobbles littered across the surface.
