PASADENA, Calif., March 11 () -- A spacecraft on a final fly-by of Saturn's moon Rhea has captured detailed images of a battered, scarred surface and some curious features, NASA says.Cassini spacecraft images show the scars of collisions with many space rocks but astronomers say they are focusing on a curving, narrow fracture known as a graben, a block of ground lower than its surroundings and bordered by cliffs on either side.This feature appears remarkably recent,[url=http://www.sorkan.com/]christian louboutin homme[/url], cutting most of the craters it crosses with only a few small craters superimposed, a release from NASA's Jet Propulsion Laboratory in Pasadena, Calif., reported Monday.Flying by Rhea at an altitude of 620 miles, Cassini's camera's captured 12 images of Rhea's rough and icy surface,[url=http://www.godsdrama.com/]true religion outlet[/url], researchers said.It was Cassini's fourth close encounter with Rhea.
