Explanation:
When orbiting Saturn, be sure to watch for
breathtaking superpositions of
moons,
rings, and
shadows.
One such
picturesque vista was visible recently to the
robot Cassini spacecraft now orbiting Saturn.
In late February, Cassini captured
Rhea,
the second largest moon of Saturn,
while looking up from slightly beneath Saturn's expansive
ring plane.
Signature dark gaps are visible in the nearly edge-on rings.
A shadow of
Saturn's F ring
cuts across the cratered ice-moon.
Cassini is scheduled to continue sending back images from the orbit of Saturn until at least 2008.
