Next stop: Saturn.

The Cassini spacecraft, launched from Earth four years ago, has now swung past Jupiter
and should arrive at Saturn in the year 2004. Pictured to the left is a parting shot
from Cassini in January that would not have been possible from Earth: Jupiter showing
a crescent phase. From the Earth and all points sunward of Jupiter, the gas giant will
always appear more fully lit than a crescent. After arriving at Saturn, Cassini will
decelerate to orbit the ringed world and send a probe to its enigmatic moon Titan.
