Yes, nice to see the imaging footprint details. The basemap has kind of a familiar look to it
Should be interesting to see some new areas being imaged at higher resolution than in previous encounters (both northern and southern). -------------------- Steve [ my home page and planetary maps page ]

I'm a bit confused about the what the highest resolution of the images will be. This description claims that the ISS will take images up to meter-scale, but I can swear on that I saw another description somewhere that said that the images taken will at most be 200 meters/pixel. While I guess that's technically meter scale I'd like confirmation on that.

Adam, there's a more detailed mission description here that details the resolution of the NAC whether it's 'prime' or 'ride-along' throughout the encounter.

There's now a multi-person blog about the Enceladus encounter on the Cassini web site. Just three posts so far (including one from me ), but more will be posted soon.

One of you guys on the Cassini team needs to please get ahold of the webmaster for the official Cassini site, and tell them that the date on the simulator (Where is Cassini now?) is out of whack.
Tried sending a discreet email this afternoon, but ... |

I kind of lost track of when the C/A distance was set to 50 km as opposed to the 38 km figure stated earlier. What were the reasons the altitude was raised?
Great idea on a blog, too. Looking forward to new entries! -------------------- |

Thanks for pointing out the problem with the "Where is Cassini Now?" page- I just sent in a note about it.
The close approach distance on Rev. 61 was raised due to a desire to be a little more cautious about the plume hazard, I believe. We'll review the plume data from this flyby in order to decide whether to maintain the planned 21 km approach distance on Rev. 88. John. |

Whoa! 21 km? Talk about threading the needle there...
You've really got to admire the accuracy with which the navigation team's flying a spacecraft some 1.5 billion km away. -------------------- |

Technically speaking, we should admire it *after* the flyby. BEFORE the flyby, we can still admire their bravery though. :-)

Well, in all honesty, they've proven this time and time again. The most recent cancellation of the final targeting maneuver just shows how good a hold of the trajectory they really have.

I've never had any feedback from any message/email i've ever sent. Well, I know for a fact that Alice Wessen (head of Cassini outreach) has personally attended to that very task until very recently, and it's now in someone elses hands. If you've got a specific case in point, let me know and I'll pass it on. Dave 'the navigator' Seal is working on the simulator to get it sorted. There's server shifts and recompiles involved. Doug |

I always pray that they're remembering to aim 21 km above the SURFACE, not from the center!
