[UPDATE] Cassini exits B-ring occultation, passes closest approach to Saturn,
....JPL now reports that Cassini has exited from behind Saturn's
B-ring, signal is strong in the 8-10db range. C-ring is providing almost no signal interference whatsoever as the end of the SOI burn comes to an end. Note that telemetry does confirm that the burn is going slightly ahead of schedule, and that the engine is probably in an overburn mode of a couple of percent above expectations. ....On a side note, once SOI is completed, Cassini will have ~1.5 hours of continuous burn fuel left in the primary engine. Considering the overburn, YMMV. ....On another side note, those expecting images during the ring plane pass will be disappointed. While JPL and the Cassini team didn't talk much about it, all imaging systems were turned off during the plane passage. Magenetometers were running fine, tho, so some science was done. May have been the logical thing to do, but there's those old animations from Voyager of the ring plane crossings that all of us would have loved to have seen for real :-( OM -- "No ******* ever won a war by dying for | http://www.io.com/~o_m his country.

Kind of a bummer. Between that and Galileo's death dive on the dark side we missed some awesome pictures I'll bet. |

Hell, I'm just glad Cassini's made it through unscathed.... and looking forward to information from Saturn in the next four years. ....Same here. Still, it would be interesting to find out if there's enough fuel for such a crossing when it's time to wind up the mission. Sure would beat the hell visually out of dropping it into Saturn first :-) Thanks for the updates, OM. ....Hey, no prob. Who says I don't contribute around here? :-P OM -- "No ******* ever won a war by dying for | http://www.io.com/~o_m his country.
