Just 8 days until the next Enceladus encounter.
CICLOPS Rev 80 Looking Ahead will appear here soon. Cassini Enceladus 080EN Mission Description is here now. We get to fly through the south polar jets again. -Floyd [edit] Soon = somtime before encounter ![]() -------------------- |

The distant (~450,000 km) images from today's 3 hour "early" downlink seem to be do down. At a quick glance I didn't notice any plume material but the automatic contrast stretch messes things up so this may not mean anything.

They may not be conspicuous here due to the viewing/lighting geometry (brightest part behind the limb, phase angle not high enough etc.). |

They probably *are* poking behind, but at that point they're very faint and diluted. I wouldn't expect to see them even in calibrated imagery, a simple sunlit sliver is enough scattered light to drown out anything near.
