To lazy to to check, is Iapetus in a proper orbit for saturnshine images?

To lazy to to check, is Iapetus in a proper orbit for saturnshine images? There is no "proper" orbit for saturnshine images. Every orbit will carry the moon over Saturn's dayside eventually, if it's a circular orbit it will do so for half the orbital period. This is the time when the sub-saturnian hemisphere of the moon receives saturnshine. The brightness obviously depends upon distance from Saturn and the phase angle at which Saturn appears. -------------------- |

I created a simulated Iapetus view with Celestia for Jul 19, 2004: Maybe I'll add an animation later. When actually was your super-res taken? Bye. I will have to research that. I lost the work in my computer crash, and I only have the finished product because I posted it to this forum and downloaded it again...Without the original files, I can't say for certain which images I used, although I know I used an entire set and that it was the closest set I could find taken prior to orbit insertion. -------------------- |

I did a Celestia run for July 2004 and found that Cassini had a closest approach at about 0900 UT on July 13, and this just about matches Ted's super-res image! I am currently checking to see if this can add detail to my map. This image really does seem to have a lot of detail for 2330000km distance.
Ted, I was unable to spot the original images on the raw images page, so perhaps you had done your processing using PDS images? -------------------- Steve [ my home page and planetary maps page ]

..., I was unable to spot the original images on the raw images page,... Hi Steve!Try this one: http://saturn.jpl.nasa.gov/multimedia/imag...feiImageID=7174 ...and the following images. Quite a lot of stuff I've never had a detailed look at... Bye. |

Hi,
Here a Iapetus picture gallery from the German FU-Berlin. Some images were unpublised until now. Bye. |

Keep in mind that they're NOT the nightside; they're the dark side (Iapetus being the only moon that genuinely has one).

Hi,
ever seen this series? This enormous southern bassin is really remarkable. Remembers quite a bit of the large craters on Tethys: Left: Melanthius Right: Odysseus --------------------------------------------------------------------------------------------------------------------------- Btw, 'Solar System Viewer' is now working with an updated Iapetus texture, finally... Here five views from CASSINI: Pretty improvement... QUOTE To lazy to check, is Iapetus in a proper orbit for saturnshine images? And one from Saturn today: Luckily sunshine outshines saturnshine today... Due to its bounded orbit you can recognize the saturnshine side of Iapetus. Bye. |
