A day after entering orbit around Saturn, Cassini sped silently past Titan, imaging the moon's south polar region. This natural color image represents Cassini's view only about two hours after closest approach to the moon. The superimposed coordinate 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 -- lines of longitude converge on the South Pole above the center of the image. The yellow curve marks the position of the boundary between day and night on Titan. Images taken through blue, green and red filters were combined to create this natural color view. The images were obtained using the Cassini spacecraft wide angle camera on July 2, 2004, from a distance of about 347,000 kilometers (216,000 miles) from Titan and at a Sun-Titan-spacecraft, or phase angle of 62 degrees.
