Original Caption Released with Image:
This image shows a three-dimensional model of the trench dug by the Mars Exploration Rover Spirit at a shallow depression dubbed "Laguna Hollow" on the 47th martian day, or sol, of its mission. The rover dragged one of its wheels back and forth across the surface to create this 7-centimeter-deep (3-inch) hole. Afterwards, it investigated the freshly exposed soil with the scientific instruments located on its robotic arm. This model was created using images from the rover's panoramic camera.
