Just 7 days until the next Enceladus encounter.
CICLOPS Rev 88 Looking Ahead should appear here before the encounter. Cassini Enceladus 088EN Mission Description shold appear here soon. We get to fly through the south polar jets again. -Floyd -------------------- |

I must confess that I haven't gotten excited about the Saturn encounters in advance, but this little world has really captured my interest. I can't wait for this one.

I created a simulation of this encounter using an experimental ground track feature in Celestia:
http://www.youtube.com/watch?v=R20d8sJae4E The trajectory is marked off in three second intervals. What's amazing to me is how damned fast the encounter is: the video is in real time. I'm so used to thinking spacecraft flybys as fairly leisurely affairs, with ample time to aim cameras and other instruments. But this is barnstorming! I'm even more impressed now with the success of the 'skeet shoot' technique used in the August encounter. Bravo, Cassini team! (The video looks much better without YouTube's compression: 2.0M AVI, DivX: http://www.shatters.net/~claurel/celestia/...dus-9oct08.avi) --Chris |

I hate those truncated lines, especially how they totally trash binned frames. There HAD to be a better lossless (LOL - "lossless") algorithm than that.
Yeah, I know the cameras were designed in the mid-90s... -------------------- |

Everything went great for the Cosmic Dust Analyzer (CDA) during this flyby. We got good data during the entire flyby—before, during and after closest approach. We recorded mass spectra even in the deep plume with no data gaps as far as I can see.
The High Rate Data rate count profile shows pronounced peaks at the time we traversed the jets. This data is key for pinning down the structure of the dust jets. The source of information is Cassini Team Blog (Sascha Kempf). -------------------- Free software for planetary science (including Cassini Image Viewer).

QUOTE (ugordan @ Oct 10 2008, 12:10 PM) I hate those truncated lines, They are more of a problem in the jpegs. In the real raw images, they are the only thing that registered as absolute black before calibration, so I can deinterlace the affected areas without damaging the non-interlaced sections. The effects of the jpeging make this impossible without damaging shadowy areas as well. -------------------- |
