Epimetheus (116 kilometers, or 72 miles across, at right) and Janus (181
kilometers, or 113 miles across, at left) are lit here by reflected
"greylight" from Saturn. The Sun brightens only thin slivers of the moons'
surfaces.
A few large craters on Janus are visible in the dim light of Saturn.
The image was taken in visible light with the Cassini spacecraft
narrow-angle camera on Nov. 29, 2005 a distance of approximately 1.1
million kilometers (700,000 miles) from both moons. Resolution in the
original image was 7 kilometers (4 miles) per pixel. The image has been
magnified by a factor of two and contrast-enhanced to aid visibility.
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.
