NASA's Cassini spacecraft successfully completed its second-closest encounter with Saturn's icy moon Helene on June 18, 2011, beaming down raw images of the small moon. At closest approach, Cassini flew within 4,330 miles (6,968 kilometers) of Helene's surface. It was the second closest approach to Helene of the entire mission.
