Scientific paper

The Mars Exploration Rovers Spirit and Opportunity observed changes in the surface soils and dusts as a result of local wind activity. The dustier Spirit landing site documented a series of dust deposition and cleaning events on the rover and surrounding terrain, redistribution of fines excavated by the rover wheels, small ripple migrations, disappearance of rover wheel tracks, and albedo changes. Opportunity also observed rover tracks fade, redistribution of sands associated with a streak exterior to Victoria crater, and small changes at Santa Maria crater. All such events emphasize the active nature of Mars at both landing sites.
