CICLOPS: Cassini Imaging Central Laboratory for OPerationS

March 31, 2001

Dear Visitor,

Cassini's Jupiter flyby officially came to a close at the end of March, when routine imaging of the planet and its satellites and rings ceased and the spacecraft was buttoned up for the cruise to Saturn.

In all, about 26,000 images were collected -- a bounty that is Voyager-class in size. Our initial findings to date, recorded on the pages of this website (Imaging Diary: Jupiter) indicate promising new directions of research in the study of Jovian atmospheric dynamics, the production of polar stratospheric haze, the nature of Jovian lightning, auroral processes in the planet's northern and southern hemispheres, the interactions between Jupiter's magnetic field and the tenuous atmospheres of some of the Galilean satellites, and much more. The results from the other Cassini instruments have proven equally rewarding. Scientists will surely be poring over these data for years to come.

Cassini left the Jovian system on a trajectory that kept its view of Jupiter nearly constant with respect to the Sun. That view is shared with all of you today in a release of a mosaic of images taken by the narrow angle camera on January 15, 2001, about two weeks after the spacecraft's closest approach to the planet. No human has yet been far enough from the Sun to enjoy such a view with his own eyes. And until we bodily transport ourselves across the solar system and beyond the orbit of Jupiter, no one ever will. Perspectives like this come only as a result of our explorations with robotic space travelers like Cassini.

We are also releasing today a color rendition of an earlier black and white Io eclipse movie, making it easier to see and distinguish the different glows emanating from the moon when in the dark of Jupiter's shadow.

Now, Cassini scientists are turning their attentions towards preparations for Cassini's arrival at Saturn in July, 2004. To those of us who have been part of this mission for the past decade, it seems only around the corner.
