Flying By Saturn's 'Death Star' Moon Mimas

Saturn's moon Mimas is dominated by a huge, unmistakable crater called Herschel that makes the moon look like the Death Star in the movie "Star Wars." On Feb. 13, 2010, NASA's Cassini spacecraft made closest-ever flyby of Mimas, returning this photo and others in spectacular flyby. Mimas is 246 miles (396 kilometers) across.
