This close-up view of Saturn's moon Janus shows what appear to be two
large craters near the boundary between day and night. The left side of
the moon is lit feebly by reflected light from Saturn. Janus is 181
kilometers (113 miles) across.
The image was taken in visible light with the Cassini spacecraft
narrow-angle camera on Feb. 18, 2005, at a distance of approximately 1.1
million kilometers (684,000 miles) from Janus and at a
Sun-Janus-spacecraft, or phase, angle of 108 degrees. Resolution in the
original image was 7 kilometers (4 miles) per pixel. The image has been
contrast-enhanced and magnified by a factor of three 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 team is based at the Space Science
Institute, Boulder, Colo.
