From hundreds of thousands of kilometers away, the Cassini spacecraft
spies craters on the surface of the moon Janus.
This view looks toward the Saturn-facing side of Janus (179 kilometers, or
111 miles across). North on Janus is up and rotated 27 degrees to the
right. The image was taken in green light with the Cassini spacecraft
narrow-angle camera on May 25, 2009.
Scale in the original image was 4 kilometers (3 miles) per pixel. The
image has been magnified by a factor of two and contrast-enhanced to aid
visibility. The view was acquired at a distance of approximately 730,000
kilometers (454,000 miles) from Janus and at a Sun-Janus-spacecraft, or
phase, angle of 38 degrees.
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.
