Excerpt from Cassini Significant Events for 02/16/06 - 02/22/06:
"As mentioned in previous weeks, the project has been working on adopting a new reference trajectory in order to raise the minimum Titan flyby altitude for various encounters. Today the project reached a decision to proceed with the 'optocc2' trajectory. Additional work is still to be performed before delivery of the final files. This will include minor tweaks that have been analyzed in other trajectories, adjusting orbit 68 timing, and capture of an Enceladus plume occultation on orbit 28." For the record, the new reference trajectory will result in an even more spectacular Enceladus-3 flyby [61EN (t) E3] on March 12, 2008. |

Even though the encounter distance is closer, don't expect too much better imaging. We come in at high-phase, C/A is over the night side, and Enceladus goes into eclipse 3 min. after C/A.

-------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Unfortunately, the distance for E3 quoted is the distance to the center of enceladus for the old flyby altitude. The old altitude was 100 km, now it is much lower. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
