I believe Rhea and Enceladus get some good views on this flyby. Not sure if both will get coverage.
maybe VP can clear this passes observations.

Rev010 closest approaches:
Mimas 257,000 km Enceladus 405,000 km Tethys 183,000 km Dione 537,000 km Rhea 244,000 km Titan 877,000 km Hyperion 1.322,000 km Nothing interesting 'satellite-wise' this time. However, mid-July (Rev011) will be interesting: Mimas 381,000 km Enceladus 172 km (July 14) Tethys 509,000 km Dione 340,000 km Rhea 180,000 km (great view of the south polar region) Titan 1,005,000 km Hyperion 1,429,000 km |

Bjorn Jonsson where do you find these precise information on flyby distances???

Tethys 183,000 km
The Tethys flyby looks not-too-bad. I wonder if they took pictures. -------------------- |

QUOTE (Toma B @ Jun 26 2005, 12:49 PM) Bjorn Jonsson where do you find these precise information on flyby distances???  There are some SPICE kernels out there that I downloaded. These files contain information on Cassini's trajectory, satellite orbits etc. I then ran these through a program I wrote to calculate things like closest approach distances, viewing geometry etc. I might generate a big table for the entire tour one day... Regarding the Rev010 Tethys flyby, the phase angle was rather high (123 degrees) at closest approach. |

There are no targeted observations of any icy satellite in Rev 10, as far as I know. There maybe some small satellite images, but that's as far as I can tell. Don't forget, OPNAVs can always be useful, but they usually aren't taken a few days +/- periapsis.
BTW, Bjorn, where are there publically available spice kernels? -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Looks like we have Rhea and Prometheus to come from this orbit, judging by the raw image pages with (as yet) broken links... maybe tomorrow.

Here's the new Prometheus image. This is a composite of five frames. I'm a bit uncertain about the orientation, but I think we are looking at the trailing side from the south, and I've rotated it so north is near the top, Saturn to the left. (might be wrong).
Images like this might not look like much but they are absolutely essential to determine the 3D shape and volume of the satellite (we need as many different views as possible), and from that the bulk density, porosity etc. Of course high resolution for surface morphology will also be very nice if we can get it!

... and here's Rhea from the new sequence, a composite of three images to remove some of the JPEG artifacts, plus a bit of creative processing.

Nice! I'm sorry I had completely forgotten about this Rhea stuff. It was much below the resolution of data we have gotten before on this region and data we will get next month so I didn't think much of it. Obviously, this is a zero phase angle observation sequence of Rhea looking at the south polar region and ray crater region. In the upper left on Phil's version at about the 10 o'clock position, you can see Tirawa in profile along the limb. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Will we be seeing a release of the processed versions of the Titan south pole observations from the last orbit?
