Fascinating little moon - looks like it's been hoovering up ring particles for aeons. Small point, but the distance to target quoted (180,000km) is clearly not correct - these shots are a helluva lot closer than that. I hope we get some additional shots later in the mission with a different viewing geometry. Thanks Ian R for the stacked and cleaned image - very nice.

The distance is around 42,000 km.

Why is there so much noise in the images -- is it just because we're real close to Saturn and there's lots of charged particles flying around?

It's not noise - Atlas has decided to outgas, too wink.gif

Thanks Ian for the beautiful Atlas staked image.
Is one of the oddest and most fascinating things I ever looked to! ohmy.gif

Very nice Ian!
Here's an enlarged version of the what I think is the best prior view of Atlas from June 2005 for anyone who hasn't already seen it. Pretty sure south is at the top in this one.

Yes, thanks Ian...

This is just stunning!!!! Wish I could crawl (what would the word be for pulling one self along a moonlet so small we are talking microgravity... you poets out there... can you find a word??? Stu???) along that polar cusp and watch ring material "fall" along the equator like an eternal snow squall ... would almost beat out hiking Headlands!!!!!! biggrin.gif

WOW.

Hmmm... "bellying"? or, with all those teeny bits of rock and dust scruffling under you, how about "skree-ping"? Or, thinking back to the movies...

"Golluming"? wink.gif

My own versions of the two best Atlas images to date, blogged today. I'm not convinced that my putting them in color brought anything to the party...

"Golluming"

I like that. I am sure a whole new vocabulary will evolve when people actually get around to golluming
moonlets like this..... similar to terms used in moutain climbing, only these mountains are flying. The trick willl be to stay in contact rather than just float along. Edging and smearing along the spindrift and scree,
and not become a permanent addition to the gravel pit. And in the vicinity of rings, kevlar suits will be mandatory (any one know the velocity of ice grains colliding and adding to this moonlets girth?)...

sorry Doug... I know this speculaton and dreaming is way off topic.... but sometimes cannot help but muse what fun our descendants may have.... about which we can only imagine...

Emily...

I like the color.... definitely adds to the party... assume the blue specks along the pole are artifacts.....

Atlas seems to be swirling himself together like wrapping a turban around his girth. I will bet this moonlet has changed it's aspect many times since the rings were born.....

Hmmm, you don't happen to be a Good Eats fan, do you? smile.gif
The color makes it seem more like being there, which is always a good thing for us enthusiasts.

In fact I am a Good Eats fan -- didn't realize I was parroting Alton Brown there!

I'll bet AB was a fan of Mr. Wizard too.

Hey, that's one of my favorite shows! I like the episode a few years back when he was stranded on a deserted island la Cast Away.

No doubt. And I know he is a big MacGyver fan.

Gotta add: "skimming". Let's say, and why not, that you're in a spacesuit on the surface of this moon with which you have barely any gravitational connection. You reach out in front of you to a small encrusted projection, barely a minor ridge within your formerly terrestrial frame of reference but a mountain here...and you pull on it as if you were diving along a coral reef...and you move with surprising velocity over the snowy surface, at an altitude of centimeters, looking for the next ridge to shove you ever onward...

Blissful. A deep dream come alive. Float almost effortlessly across a surface, and scoop a handful of the rings of Saturn as you pass by, glance up and see Saturn huge in front of you, the major moons as bright stars or perhaps barely resolvable tiny crescents if you're particularly lucky...who could want anything more?


--------------------
A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
