NASA's Mars Exploration Rover Spirit acquired this high-resolution view of intricately layered exposures of rock while parked on the northwest edge of the bright, semi-circular feature known as "Home Plate." The rover was perched at a 27-degree upward tilt while creating the panorama, resulting in the "U" shape of the mosaic. 246 separate images of this scene were acquired using 6 different filters on the panoramic camera (Pancam) during the rover's Martian days, or sols, 748 through 751 (Feb. 9 through Feb. 12, 2006). The field of view covers 160 degrees of terrain around the rover. In image b, of the lower coarse-grained unit, granular textures toward the bottom of the image. Image d contains a feature interpreted to be a "bomb sag," 4 centimeters across. This false color image was obtained using Spirit's panoramic camera.
