IMAGE CAPTION                     PIA-02572                                                                        
                                  Region of Ganymede with mix of 
                                  terrains
                                  December 16, 2000

     The area of Nicholson Regio and Arbela Sulcus illustrates 
many of the diverse terrain types on Jupiter's moon Ganymede, as 
seen in this image taken by NASA's Galileo spacecraft.

     The bright terrain of Arbela Sulcus is the youngest terrain 
here, slicing north-south across the image. It is finely 
striated, and relatively lightly cratered. To the east (right) 
is the oldest terrain in this area, rolling and relatively 
densely cratered Nicholson Regio. To the west (left) is a region 
of highly deformed grooved terrain, intermediate in relative 
age. In this area of grooved terrain, stretching and normal 
faulting of Nicholson Regio has deformed it beyond recognition. 

     North is to the top of the picture and the Sun illuminates 
the surface from the west. The image, centered at -15 degrees 
latitude and 347 degrees longitude, covers an area approximately 
89 by 26 kilometers (55 by 16 miles). The resolution is 34 
meters (112 feet) per picture element. The images were taken on 
May 20, 2000, at a range of 3,350 kilometers (2,082 miles).
