They attempted their first trenching today. Looks like the soil underneath is a much lighter color.

Looks quite cool actually - cleaner trench than I expected.

But the debris pile to the left of the image looks about the same intensity of color as the surface sediment.

Two-way spinning.

"Opportunity Digs; Spirit Advances

"NASA's Mars Exploration Rover Opportunity has scooped a
trench with one of its wheels to reveal what is below the
surface of a selected patch of soil.

"Yesterday we dug a nice big hole on Mars," said Jeffrey
Biesiadecki, a rover planner at NASA's Jet Propulsion
Laboratory, Pasadena, Calif.

"The rover alternately pushed soil forward and backward out of
the trench with its right front wheel while other wheels held
the rover in place. The rover turned slightly between bouts
of digging to widen the hole. "We took a patient, gentle
approach to digging," Biesiadecki said. The process lasted 22
minutes.

if you look, there's also a mound on the right, and that's where the pale soil extends out of the trench, and has been rolled over as the Rover extricated itself. wink.gif
