A new study in the journal Icarus provides the latest round-up of the number of impact craters found on Saturn's moon Titan.
Between 2004 and December 2007, Cassini had surveyed 22 percent of Titan's surface. Scientists analyzed images taken by the spacecraft's high-resolution Radar Mapper instrument, and found 49 impact craters.
"Impact craters are created on every planet because of asteroids, comets and other debris that collide with their surfaces," said Charles Wood, senior scientist at the Planetary Science Institute in Tucson, Az, and lead author of the study. "Analyzing impact craters is a standard technique to tell you the history of the world."
