Farewell Jupiter.

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 .
