Scientists have pieced together the first-ever global topographic map of Titan, Saturn's largest moon, using radar observations from veteran NASA spacecraft. The new map of Titan was stitched together from radar observations of the moon by NASA's Cassini spacecraft. It reveals an unprecedented look at Titan's surface and should help scientists learn more about one of the most Earth-like bodies in the solar system, members of the mapping team said. "Titan has so much interesting activity — like flowing liquids and moving sand dunes — but to understand these processes it's useful to know how the terrain slopes," Ralph Lorenz, a member of the Cassini spacecraft's radar team at the Johns Hopkins...
