NASA's Curiosity Mars rover took this image with its Mast Camera (Mastcam) on Feb. 10, 2019 (Sol 2316). The rover is currently exploring a region of Mount Sharp nicknamed "Glen Torridon" that has lots of clay minerals.
Malin Space Science Systems, San Diego, built and operates the Mastcam. NASA's Jet Propulsion Laboratory, a division of the Caltech in Pasadena, California, manages the Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington. JPL designed and built the project's Curiosity rover.
