Monday is the next scheduled PDS release of Cassini data. ISS and VIMS data for this release is already posted at http://pds-imaging.jpl.nasa.gov/data/cassi...assini_orbiter/ with RADAR data to come in the following week. This release includes data from October 1, 2005 through December 31, 2005, cover periapse passes from rev16 through rev19. Some of the highlights from this time period include:

Here are a couple of frames from VIMS taken right before Closest approach on T9 (both images magnified 4x):
v1514315553_1 - Aimpoint distance: 11788 km; pixel scale of original 64x64: 5.78 km/pixel v1514315913 - Aimpoint distance: 11315 km; pixel scale of original 64x64: 5.55 km/pixel Both images are centered near 9.6 South, 64.3 West. Both use the image at 2.018 microns. These images show an area in far eastern Xanadu, in the strip of bright terrain between the western ends of Fensal and Aztlan. In the second image, you can see dark terrain from Fensal and Aztlan in the upper right and lower left corners, respectively. These frames are also located near the eastern end of the T13 SAR swath: http://photojournal.jpl.nasa.gov/catalog/PIA08552 -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Wow, has it been that long? These views seem like only yesterday...
BTW, volcanopele -- the IR channel in the VIMS cubes doesn't necessarily have the same pixel scale in the horizontal and vertical direction. The horizontal resolution is often greater, resulting in a sort of vertically flattened appearance of the cube. In fact, if you compare your two cubes, you can see the upper one is "stretched" horizontally. -------------------- |

If that's directed to me, thanks!
The colors aren't particularly accurate, though -- the composites are IR-GRN-UV, toned down to make them more "natural". Here are a couple of actual red/green/blue composites: Left to right: Tethys, Rhea and Dione. -------------------- |

Lastly, two snapshots of the Iapetus flyby. I've been waiting for this stuff to hit the PDS...
The left image is a stretched color composite processed to better match the natural color and was magnified 2x. The other one is an approx. true-color red/green/blue composite. -------------------- |
