This false-color image shows the area within "Endurance Crater," currently
being investigated by the Mars Exploration Rover Opportunity. The rover
is inspecting a hole it drilled into a flat rock (center) dubbed
"Tennessee," which scientists believe may be made up of the same
evaporite-rich materials as those found in "Eagle Crater."
The overall geography inside Endurance is more complex than scientists
anticipated, with at least three distinct bands of rock visible in front
of the rover. Scientists hope to investigate the second and third layers
of rock for more clues to Mars' history. This image was taken on sol 133
(June 8, 2004) with the rover's panoramic camera, using the 750-, 530-
and 430-nanometer filters.
