Summary

[edit]
Description

20 frame mosaic of Callisto taken by Voyager 2 on July 8, 1979, during the spacecraft's encounter with the moon. The subframes for this mosaic were taken between 1211-1303 UT.

During 52 minutes it took to acquire the data for this mosaic, Voyager 2's viewing angle changed dramatically. This mosaic does not correct for the geometric distortion that caused. This image acquisition started in the south when Callisto was still in a slightly gibbous phase from Voyager's viewpoint, and ended in the north with Callisto presenting a slight crescent phase. This distortion is evident as a twisting of the terminator.

Low-resolution color images were taken simultaneously, but these were too grainy to produce an acceptable color overlay. This image has been colorized by taking the average color of Callisto from the color data set, and applying it globally.
