This image is cropped from the 360-degree view below. The image was assembled from frames taken by the panoramic camera aboard NASA's Mars Exploration Rover Spirit from a position beside the crater informally named "Bonneville." Half of this panorama was first released on March 15, 2004. The tracks from Spirit, as well as a glimpse of part the rover, are visible in this crop.
The entire mosaic (visible in the link below) reveals the crater rim and interior. The images were acquired on sol 68, March 12, 2004, just one day after Spirit reached this location.
The image is a false-color composite made from frames taken with the camera's L2 (750 nanometer), L5 (530 nanometer) and L6 (480 nanometer) filters.
