Wheel Excavation of Tyrone
The Spirit rover acquired these images of an area called "Tyrone" on Sol 788 (March 22, 2006) after the wheels excavated large deposits of light-toned soil. Spirit's instruments found this material to have a salty chemistry, dominated by iron-bearing sulfates, similar to other areas of disturbed soil at "Arad" and "Paso Robles." "Paso Robles" was found in 2005 while climbing "Cumberland Ridge" on the western slope of "Husband Hill," and "Arad" was found in early 2006 on the basin floor just south of "Husband Hill."
This mosaic was acquired in Pancam's 753-nm, 535-nm, and 432-nm filters. The distance between wheel tracks is about 1.5 meters. Two versions are offered here at full resolution: an approximately true color rendering, and a false color stretch to bring out subtle color differences in the scene.
