Rim of 'Erebus'
The center upper portion of this image shows a portion of the rim of "Erebus Crater" in the Meridiani Planum region of Mars.
This approximately true-color view from the panoramic camera on NASA's Mars Exploration Rover Opportunity is a composite of frames acquired on the rover's 657th Martian day, or sol, (Nov. 28, 2005).
This is a small portion of a large panorama. Other portions of the panorama were still being shot three sols later. This view is a composite of separate images taken through the camera's 750-nanometer, 530-nanometer and 430-nanometer filters.
