Close-up of Brushed Area on Martian Rock Target 'Ekwir_1'This image from the Mars Hand Lens Imager (MAHLI) on NASA's Mars rover Curiosity shows details of rock texture and color in an area where the rover's Dust Removal Tool (DRT) brushed away dust that was on the rock. This rock target, "Ekwir_1" was brushed and this image was recorded on the same Martian day, or sol, Sol 150 of Curiosity's mission on Mars (Jan. 6, 2013.)
The image, one of the highest resolution images returned so far by MAHLI, was taken from a distance of about 0.4 inch (1 centimeter) from the rock's surface. Fractures, white veins, pits and tiny dark grains in the rock are visible, as well as remaining clumps and specks of dust. The scale bar at lower left is 2 millimeters (0.08 inches).
