A mineral vein with bright and dark portions dominates this image of a Martian rock target called "Rona," which is near the southern, upper edge of "Vera Rubin Ridge" on Mount Sharp.

The Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity Mars rover took this image on Jan. 17, 2018, during the 1,937th Martian day, or sol, of Curiosity's work on Mars.

The grayer area in the center is roughly 2 inches by 3 inches (about 5 by 8 centimeters). That area, including a portion of the vein, was brushed with the Curiosity's wire-bristled Dust Removal Tool before the image was taken.

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.
