TELEPHONE: (213) 354-5011/ PHOTO CAPTION Voayger 1-133/ P-21284 C/ March 30, 1979/ This color photo of Jupiter's satellite Callisto was made from/ three black-and-white images taken March 5 from a distance of/ 746,000 miles (1.2 million kilometers). It shows the entire/ hemisphere of Callisto that was photographed at high resolution/ by Voyager 1 during the close encounter with the satellite on/ March 6. Visible near the upper left limb is the large basin-like/ structure discovered by Voyager 1. The central region of the basin/ is much brighter than the average surface of the satellite. Near/ the south polar region are two bright areas associated with smaller/ basin-like structures. These bright areas are believed to contain/ more clean ice than the rest of Callisto's generally "dirty-ice"/ surface. The Voyager project is managed and controlled by Jet/ Propulsion Laboratory for NASA's Office of Space Science.
