WOW! Lots of coverge!
Looks like filling Low res images will be fun for the Mapers. |

There are a few pictures of Enceladus coming in, these are on the CICLOPS site, they haven't appeared on the JPL RAW page yet
http://ciclops.lpl.arizona.edu/view_event.php?id=11 Only a few hours to go until closest approach

And I though Europa was melting.
One side looks totally reworked. |

In the latest image, parts of the Moon, particularly towards the lft limb, seem to resemble some of the cracks seen on Europa.

OMG! I'm Floored!
  This moon looks more like Ganymede! How deep can those grooves be? |

Enceladus looks even more strange than I expected - remarkably similar to Europa in fact. And I can't see a single impact crater in this image (there are a few features that at first glance looked like craters but I think they are mounds). |

That deep fracture is impressive!
The young areas of Enceladus seem to show a much greater range of topography than Europa. If so, Enceladus' putative ocean/warm ice is likely *less* accessible today than the one belonging to its smooth jovian cousin. This area of the crust must be cold and brittle to great depths to support these topographic features. It looks like we arrived too late. |

Having looked at more images I now realize that what I first thought were craters and then thought were mounds really are craters:
 There are both ridges and grooves there. Looks like a strange mix of Europa and Ganymede to me. However, judging from the craters at least this area is hardly active now. |

However, judging from the craters at least this area is hardly active now. Perhaps Enceladus went through successive stages of Europa-like 'cracked-eggshell' terrain and Ganymedean 'ridges & grooves' tectonism as the warm-ice retreated to greater depths. The process seems to have ended with these deep (Dione-esque) fractures. |

Why is there so much missing data on the right hand side? Can they correct that?
The ridges in this shot look quite like the ones on Europa http://saturn.jpl.nasa.gov/multimedia/imag...8/N00028194.jpg |

Looking at the distant images, I don't think these show the very youngest looking terrain that we saw on TC. There may be some younger terrain yet on this moon.
