Saturn's moon Dione floats in the dark sky before Cassini in this
anaglyph, or 3D image, taken during an encounter in late 2005. Images
taken from slightly different directions allow construction of stereo
views such as this, which are helpful in interpreting the complex
topography of Saturn's moons.
Dione (1,126 kilometers, or 700 miles across) is covered with bright, icy
cliffs revealed by Cassini.
A non-anaglyph view, taken at nearly the same time, was previously
released (see PIA07581).
The images in this anaglyph were taken in visible light with the Cassini
spacecraft narrow-angle camera on Aug. 1, 2005, at a distance of
approximately 242,000 kilometers (150,000 miles) from Dione and at a
sun-Dione-spacecraft, or phase, angle of about 45 degrees. Image scale is
about 2 kilometers (1 mile) per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the European
Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory,
a division of the California Institute of Technology in Pasadena, manages
the mission for NASA's Science Mission Directorate, Washington, D.C. The
Cassini orbiter and its two onboard cameras were designed, developed and
assembled at JPL. The imaging operations center is based at the Space
Science Institute in Boulder, Colo.
