TELEPHONE: (213) 354-5011/PHOTO CAPTION (TOP) 260-989 C/BW/S-1-50/Nov. 14, 1980/ Saturn's satellite Dione is seen in transit 377,000 kilometers/ (234,000 miles) above the clouds of Saturn in this Voyager 1/ picture made from images taken Nov. 11, 1980. The difference/ in character between the trailing hemisphere (left) and the/ leading hemisphere of the moon is apparent. The trailing/ hemisphere contains relatively dark material criss-crossed/ by wispy light streaks. The leading hemisphere (seen most/ clearly during Voyager's closest approach to Dione on Nov. 12,/ 1980) shows a relatively uniform surface with many impact craters./ The cause of the difference between the two sides of Dione/ will be one of the subjects of continuing study for the Voyager/ imaging team. The Voyager Project is managed for NASA by the/ Jet Propulsion Laboratory, Pasadena, Calif./####
