Cassini snapped this image of Saturn's moon Helene while completing the spacecraft's second-closest encounter of the moon on June 18, 2011. This flyby yielded some of the highest resolution images of the moon to date. Lit terrain seen here is on the leading hemisphere of Helene (33 kilometers, 21 miles across). The view was obtained at a distance of approximately 7,000 kilometers (4,000 miles) from Helene. Image scale is 42 meters (137 feet) per pixel. (NASA/JPL/Space Science Institute) #
