The far left image shows the location of the radar swath for the Oct. 28, 2005, flyby. On the top right is the radar swath from the first Titan flyby, on Oct. 26, 2004. The second from the top image is from the second radar pass of Titan, on Feb. 15, 2005 (near-equatorial). The bottom right swath is from the Sept. 7, 2005, flyby. Cassini's radar has revealed a variety of geologic features, including impact craters, wind-blown deposits, channels and cryovolcanic features.
