Irregular bright and dark regions of yet unidentified composition and character are becoming increasingly visible on Titan's surface as Cassini approaches its scheduled first fly-by of Saturn's largest moon on 2 July 2004.
The superimposed co-ordinate system grid in the accompanying image at right illustrates the geographical regions of the moon that are illuminated and visible, as well as the orientation of Titan. North is up and rotated 25 degrees to the left.
The yellow curve marks the position of the boundary between day and night on Titan. This image shows about one quarter of Titan's surface, from 0 to 70 degrees West longitude, and just barely overlaps part of the surface shown in the previous Titan image release. Most of the visible surface in this image has not yet been shown in any Cassini-Huygens image.
The image was obtained with the narrow-angle camera on 14 June 2004, at a distance of 10.4 million kilometres from Titan. The image scale is 62 kilometres per pixel. The image was magnified by a factor of two using a linear interpolation scheme. No further processing to remove the effects of the overlying atmosphere has been performed.
