This mosaic of images shows layers of ancient sediment on a boulder-sized rock called "Strathdon," as seen by the Mars Hand Lens Imager (MAHLI) camera on the end of the robotic arm on NASA's Curiosity rover. The images were taken on July 10, 2019, the 2,462nd Martian day, or sol, of the mission.

The images were acquired from about 4 inches (10 centimeters) away and processed to adjust brightness and remove blemishes.

Malin Space Science Systems in San Diego built and operates Mastcam. A division of Caltech, the Jet Propulsion Laboratory in Pasadena, California, manages the Mars Science Laboratory Project for NASA's Science Mission Directorate in Washington and built the project's Curiosity rover.
