Hi,
let me open this thread on the closest Iapetus flyby on September 10th later this year.
Hopefully we'll get some more clues to solve the mysteries of this odd moon, like the origin of the equatorial ridge and the brightness differance...

First, some new infos given by Tilmann Denk from FU Berlin:
CASSINI will pass Iapetus in roughly 1600 km.
An UVIS star occultation of sigma Sagitarii will now occur about 1 hour before closest approach - instead of during it.
This will now allow an additional window for high resolved pics of the highest known parts of the equatorial ridge at 160°
(phase between ~140° and ~30°) now, apparently a decisive approvement of this encounter.
Detailed planing can be started soon... smile.gif



Bye.
