In an up-close 1-inch-wide view, grains of sand near a Martian sand dune are imaged by the arm camera on NASA's Mars rover Curiosity Mars rover.

Martian Sand Disturbed by Rover Wheel

This view shows grains of sand where NASA's Curiosity Mars rover was driven into a shallow sand sheet near a large dune. The disturbance by the wheel exposed interior material of the sand body, including finer sand grains than on the undisturbed surface. Sunlight is coming from the left.

The scene covers an area 1.3 inches by 1.0 inch (3.3 by 2.5 centimeters). This is a focus-merge product from Curiosity's Mars Hand Lens Imager (MAHLI), combining multiple images taken at different focus settings to yield sharper focus at varying distances from the lens. The component images were taken on Dec. 3, 2015, during the 1,182nd Martian day, or sol, of Curiosity's work on Mars.

MAHLI was built by Malin Space Science Systems, San Diego. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Science Laboratory Project for the NASA Science Mission Directorate, Washington. JPL designed and built the project's Curiosity rover.
