The "Death Star" Moon: Mimas



The official NASA caption is "That's no space station."

I guess relating to this thread it means we are in the Star Wars universe after all.

It is intriguing that the Rayleigh scattering is only in the upper and, I suppose, lower atmosphere. This seems surprising to me. A rough guess would be only the upper regions have the smaller molecules (thanks in part to the molecular break-down the article discussed) allowing the scattering. Large molecules do not allow much scattering of shorter wavelength light.

Was there a Cassini update on NASATV today? There was something scheduled for 1pm EDT but I was out at the time.

OUT FROM THE SHADOWS: TWO NEW SATURNIAN MOONS

edit: That brings the total to 33, I believe. The article doesn't mention the total, and I haven't looked it up in a while, but I keep a running total of the solar system's moons on my desktop and at last count I had Saturn with 31.

You're correct. Satellite discoverer Scott Sheppard's site has up-to date information on giant planet satellites.

I'm sure this was discussed before: At which size they will stop to call these rocks 'moons'?

Looks like the Cassini Picture of the Day on the Cassini homepage haven't been updated...

Cassini is approaching a 1.1 million km flyby of Iapetus in the next several days and the narrow angle images will be higher resolution than any from Voyager. However, there is evidently a pointing error occurring as a number of the recent images don’t actually include Iapetus in the frame. The last narrow angle posted that does http://saturn.jpl.nasa.gov/multimedi.../N00021473.jpg shows some topography in Cassini Regio.

I understand that pointing errors have occurred earlier – an image of Hyperion from about 750,000 km was missed a day or two after SOI.

Also, after the upcoming Titan flyby there will be opportunities for imaging Tethys and Mimas from a few hundred thousand km at highest resolutions of 1.5 and 2 km/pixel respectively.

Here's a great raw image of Tethys showing it's largest crater to good effect:

Gee, don't you think that after all the work it did at Titan on Tuesday, Cassini deserves a break? But noOOO.....the scientists insist, "Now go take a picture of THIS moon!" C'mon, give Cassini a break!

:wink:

J/K Great picture! I'm so excited about all these great moon pics still to come!

...and it's still not finished yet!
