NASA’s Mars rover Curiosity acquired this image of a recent DRT (Dust Removal Tool) site, showing off the marks created in the rocks by DRT — a motorized, wire-bristle brush on the turret at the end of the rover's robotic arm — as well as a whitish vein that was revealed after the dust covering it was removed. Curiosity acquired this image using its Mars Hand Lens Imager (MAHLI), a camera mounted on the turret at the end of the robotic arm, which provides close-up views of the minerals, textures, and structures in Martian rocks and the surface layer of rocky debris and dust. Using an onboard process, MAHLI merges two to eight images to make a composite image of the same target acquired at different focus positions, to bring many features into focus in a single image. Curiosity merged this composite on June 4, 2025 — Sol 4560. Or Martian day 4,560 of the Mars Science Laboratory Mission — at 12:33:42 UTC.
