The Looking Ahead article for Rev50 was posted on Tuesday:
http://ciclops.org/view.php?id=3800 There are three, non-targeted icy satellite encounters coming up at the end of the month: Dione, Enceladus, and Tethys. The Tethys encounter has a very similar geometry to those we've seen over the last few months, showing the region west of Ithaca Chasma at moderate phase angles. The Dione and Enceladus encounters are much more interesting, IMHO. The Dione encounter will cover the sub-Saturnian hemisphere. A large mosaic is planned over that hemisphere at 270-300 m/pixel (around 20 footprints IIRC). This would allow coverage of the wispy terrain terrain there at phase angles which should make the view pretty dramatic. Also, the impact basins of the leading hemisphere should be quite visible. The Enceladus encounter will provide the best view to date of Enceladus' leading hemisphere. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Thanks, VP - and may I say, doesn't this show what an incredible mission Cassini is? One amazing encounter after another. Three years in, and we are still getting wonderful new vistas in quick succession. And a teaser for the next orbit with more untargeted encounters. Galileo would have been like this... too bad! - but Uranus and Neptune await.

Wow!!!
SAR Radar over Tseghi Radiometry over FQA supra-basin and W Shangri-La Adiri Altimetry over Adiri HiSAR over Shiwanni Virgae ISS and VIMS over Adiri This will give some really cool-o information! -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

When do these encounters get uploaded to earth? Boy I can't wait!

Images are downlinked today and tomorrow (hopefully...). Some should show up tonight, say around 9 or 10 pm PDT, and more will show up around noon PDT. Times VERY approximate.

NAC and WAC images from Dione are in, together with some images of Enceladus, but not the leading hemisphere images.

Yes, some nice shots of Enceladus' plumes, albeit with lossy compression used on longer exposures. Those Dione shots are nice and contrasty, they should make for a nice mosaic.

Dione stuff looks very nice so far! Hope the rest comes down tomorrow. I of course, want to see the Enceladus leading hemisphere images. Hopefully, you are all crossing your fingers and toes.

Here's the rough two-frame Dione mosaic, this is the first time I used GIMP (yikes, only thing available at work...) and managed to actually do something with it so be gentle:

V nice gordan
 My rather arty attempt... just having a bit of fun on a day off work, when I really should be learning my Best Man's speech for my brother's wedding on Friday...

Really Nice. Good to have some news about one of my favourite moons (I mean Dione).
Some Enceladus pictures are also available: http://saturn.jpl.nasa.gov/multimedia/imag...iImageID=129239 Thin crescent with south polar geysers. Marc. |
