This file is a stereogram. Stereograms are stereoscopic images or animations which combine left and right frames showing slightly different visual angles to allow for 3D perception.
3D red-blue glasses are recommended to view this image correctly.
English: The surface of the Martian rock target in this stereo image includes small hollows with a "swallowtail" shape characteristic of some gypsum crystals, most evident in the lower left quadrant. These hollows may have resulted from the original crystallizing mineral subsequently dissolving away. The view appears three-dimensional when seen through blue-red glasses with the red lens on the left.
The scene spans about 2.5 inches (6.5 centimeters). This rock target, called "Funzie", is near the southern, uphill edge of "Vera Rubin Ridge" on lower Mount Sharp. The stereo view combines two images taken from slightly different angles by the Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity Mars rover, with the camera about 4 inches (10 centimeters) above the target. The composite images of this stereo view were taken on Jan. 11, 2018, during the 1,932nd Martian day, or sol, of the rover's work on Mars.
