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. https://photojournal.jpl.nasa.gov/catalog/PIA23347
