Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. This is one of the first images from its new vantage point, showing the rover Sojourner near a rock named Barnacle Bill. This particularly interesting rock, with a variety of surface textures, appears to be about 8 to 10 inches high. The APXS, located at the rear of the rover, is not visible in this picture.
