Large bright streaks are seen to cross the face of Saturn's moon
Dione in this photograph taken by NASA's Voyager 1 on Nov. 12, 1980
from a distance of 695,000 kilometers (417,000 miles). Higher
resolution views of Dione taken by Voyager 1 show some of these
streaks to be grooves that may be the result of fracturing in the
satellite's surface. The Voyager Project is managed for NASA by
the Jet Propulsion Laboratory, Pasadena, California.
