QUOTE (scalbers @ Feb 28 2010, 10:28 AM)  Interesting Paul to see this blue band on both Mimas and Tethys. I also notice they both show a brownish color on their trailing hemispheres. What is the blue color from? I seem to recall reading somewhere that energetic particles could create and trap oxygen radicals in water ices. -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

QUOTE (Exploitcorporations @ Feb 24 2010, 06:26 AM) I'd like to suggest possibly using images from the 28 June 2007 pass for detail west of Herschel and the transition to the coverage from August 2005. The fine fractures and/or crater chains show up much better, and it seems to beat the resolution of the partial Voyager coverage. I'm reposting Gordan's excellent color version for reference. Greetings Exploit, Good eyes - that's a great idea about using the June 28, 2007 data. ugordan's image works nicely for this. Below is how the map looks with this image included. The overall brightness is turned up now so less detail gets lost in the shadows.
Just for fun I'll point out the new image is *east* of Herschel. Remember that movie, Krakatoa, East of Java? That's the latest, Steve |

Can someone create a comparison of Mimas and Tethys with the same size scale for both? Would be funny to see the big and baby death star at the same time.

Floyd,
I was hoping for a montage with the same scale used for both pictures. -------------------- Space Enthusiast Richard Hendricks

Remember that movie, Krakatoa, East of Java? Facepalm. Your OTHER west. The map looks great, much smoother! Thanks for considering my suggestion. I haven't seen the movie, but I see Maximillian Schnell from "The Black Hole" is in it. There is no east or west beyond the singularity, is there?

Based on the dimensions in this chart, I reduced the image of Mimas to about 38.5% of its original size to get this approximation of relative sizes.

I thought Id throw in my Herschel rendering, even tho it is based only on 4 year old lower resolution data (I am expressly forbidden from using any data less than one year old). I also include a view of cratered highlands. These views do not include the curvature of the sphere, which would be rather pronounced of course!

These seem to be more related to the gravity fields of these little moons, i.e. the grooves suggest movement of loose material toward areas closer to the center of Calypso (or Helene or Telesto).

Cassini's recent and closest flyby of Saturn's moon Mimas generated views of this "Death Star" moon in unprecedented detail and a new temperature map of its surface. -------------------- |

That temperature map is just mystifying. Is it only coincidence that Herschel is right in the middle of the cold spot? Or might it be the cause?
Reminds me of Pac-Man eating a power up!  Wonderful images anyway! |

Reminds me of Pac-Man eating a power up! Wonderful images anyway! Yes it is very interesting! It is also almost exactly coincident with the blue equatorial band we showed in our Maps of Mimas in October. We have a good idea about the cause of it but I cant say anything until our paper we submitted to Icarus last month passed peer review. anyone who knows me knows i hate being coy but Im afraid we have to wait just alittle bit longer before going public. lets just say its "electrifying" . . . -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX
