With the huge, colorful face of Jupiter as a backdrop to keep sizes in
perspective, three of that planet's four major moons are on display in new
images for release today and tomorrow from NASA's Cassini spacecraft.



Europa and Callisto are aligned with each other and the center of Jupiter
in a true-color Cassini picture available online today from NASA's Jet
Propulsion Laboratory, Pasadena, Calif., at:

and from the web site of the Cassini Imaging Science team at the
University of Arizona, Tucson, at:

A Cassini picture of the moon Ganymede at Jupiter will be available
Friday, Dec. 22.

NASA's Galileo spacecraft, which has been orbiting Jupiter for five years,
recently found evidence of a liquid ocean hidden below Ganymede's surface.
Galileo will fly past Ganymede for another close encounter on Dec. 28.

Cassini will pass Jupiter at a distance of about 9.7 million kilometers (6
million miles) on Dec. 30. The spacecraft will use a boost from Jupiter's
gravity to reach its ultimate destination, Saturn, in July 2004.

and NASA's Galileo spacecraft is available online at:
