This black-and-white image mosaic shows a pair of rover tracks moving toward the viewer across a sandy, rippled surface without details about the soil between the tracks or the view of the horizon. On the bottom left, just beneath the instruments at the end of the rover's arm, is a patch of light soil on top of the darker soil around it. On the lower right is a tiny upturned strand of light soil beside the deeper furrow created by the rover's dragging right front wheel.
Disturbed Soil Along the Path from 'Tyrone' (Close-Up)

This view shows tracks created by NASA's Mars Exploration Rover Spirit while traveling from the bright soil deposit seen in the upper right, informally named "Tyrone," to the vehicle's current location, dubbed "Winter Haven."

Spirit parked at "Winter Haven" on a small north-facing slope to maximize solar energy input during the Martian winter. This stayover presents an opportunity to do more intensive, long-term investigations of the rover's surroundings than are typically possible during warmer seasons when the vehicle spends more time driving from place to place. One of these activities is assessing the influence of wind by monitoring surface changes. Experience from the Viking Landers of the 1970s suggests that wind-related surface changes are more likely to occur in recently disturbed soil.

Shortly after arriving at Winter Haven, Spirit obtained this high-resolution view of disturbed soil for comparison with future images to help reveal any wind-related surface changes. The view is a mosaic of images of the rover's tracks, obtained through the 750-nanomater filter in the left eye of Spirit's panoramic camera on the rover's 835th Martian day, or sol (May 9, 2006).

This black-and-white image mosaic shows a pair of rover tracks moving toward the viewer across a sandy, rippled surface. The track on the right is actually a shallow trench created by Spirit's dragging right front wheel. The track on the left shows horizontally oriented grooves created by the three fully operating wheels on the rover's left side. In the background, on the horizon, is the slope of one of the
Disturbed Soil Along the Path from 'Tyrone'(Panorama)

This view shows tracks created by NASA's Mars Exploration Rover Spirit while traveling from the bright soil deposit seen in the upper right, informally named "Tyrone," to the vehicle's current location, dubbed "Winter Haven."

One of these activities is assessing the influence of wind by monitoring surface changes. Experience from the Viking Landers of the 1970s suggests that wind-related surface changes are more likely to occur in recently disturbed soil. This mosaic view combines two cameras' images of disturbed soil in Spirit's tracks, taken shortly after arriving at Winter Haven. It will provide a comparison with future images to help reveal any wind-related surface changes.

The mosaic includes images of the rover's tracks obtained through the left eye of the navigation camera on the rover's 807th Martian day, or sol (April 11, 2006), merged with higher-resolution images obtained through the 750-nanomater filter in the left eye of the panoramic camera on sol 835 (May 9, 2006).
