This
colour photo of Jupiter's satellite Callisto was made from three black-and-white
images taken March 5 from a distance of 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. |
