Simulator is fixed!
Also got back a nice reply from the Cassini Team. I assumed that it was something easy to fix, and therefore they were simply unaware. Turns out they were really dealing with some issues on it, and several people had emailed them. Just in time for the flyby, too. LINK |

Turns out they were really dealing with some issues on it I noticed that Cassini's cumulative trajectory plot is now significantly smoother. Looks like they decreased the time tick interval (at periapsis only?) by which they draw the trajectory using linear segments. It looked ugly at periapsis before because that's when the S/C covered the greatest distance per time unit. Also, I don't remember seeing anything else than Titan in the lower right view before. Neat. -------------------- |

According to the official blog on the JPL Cassini Huygens web site, the spacecraft has begun it's data download to the Deep Space Network. The download will take about nine hours.

Some flyby raws are up. Check this shot in particular. Those 'central mounds' in the larger craters are most intruiging!

Is all the snow just randomly "hot" pixels? |

Am I correct in assuming the illumination from the "bottom" is actually saturnshine primarily from the planet's southern nightside which, in turn is softly illuminated by reflected ringshine? See this image for an illustration, only in this case the rings would be nearly perfectly edge-on (not sure how much they contribute to lighting) and the sunlit crescent wouldn't be visible. Also, the two additional illumination sources on the "top" side of the moon (seen in other, even longer exposure shots) would be two of the neighboring satellites? David, the majority of those dots (actually short streaks) are stars. -------------------- |

The illumination from "below" is Saturn-shine (possibly ring shine...). The illuminator to the right is Tethys with some light from Dione (both are pretty much in the same direction). The illuminator to the lower left is Rhea.

The illumination from "below" is Saturn-shine (possibly ring shine...). This would have to be a sort of ring-saturn-shine if that's what you meant, doubly reflected and dim light off of the cloud tops. Enceladus is in such a low inclination orbit, 0.019 deg (compared to Mimas' 1.51 deg) that the main rings are effectively invisible. I wonder how much light the broader F ring would diffuse and if it would be comparable in brightness to the light flux from the night side? -------------------- |

Nice work um3k, I was waiting to see which of the resident image wizards would come up trumps first on this north pole mosaic

The JPL website must be getting hammered...I'm having a hard time getting in to the raw images. Wish I could grab them and set up a mirror somehow...
