Here's the latest Prometheus image... actually a composite of the four available when I got in to - uh - work.
 I think we are looking at the anti-Saturn end, and down the leading side, from the south. Phil -------------------- ... because the Solar System ain't gonna map itself.

And here's the new Atlas image, a composite of the three on the website this morning.
(maybe it should be upside down... this is probably the southern side) Phil

WOW - Hoagland will be having FITS over this one
 Can we expect any closer approaches in the primary mission? Doug |

It reminds me of the Mothership from the movie 'Independance Day'. I suppose that we all will have a much better view of it in three weeks.

I know some have suggested that Iapetus' equatorial bulge was formed by infalling ring material. I never took much stock in it given Iapetus' size and current position (the latter can change though), but for the equatorial bulges of these Pan and Atlas, I don't see why that explanation can't work.

Is the Hyperion set that is on the raw site complete? It seems all the images are overexposed. This is all I can get out of them.
 Was this an attempt to look for comet-like activity or a mistake? -------------------- |

They're not-overexposed, just poorly stretched by JPL. This tends to be a problem with bodies that take up only a small percentage of the image. the image you show is at ~4.5 km/pixel. We will get LOADS more over the next 3-4 days with the best images topping out at just under 1 km/pixel.

I expected the tide to orient Atlas so the long axis is pointed toward Saturn. Instead the long axis appears to parallel to its orbit. Is this just an effect of lighting and viewing angle or is something else responsible?

Is this just an effect of lighting and viewing angle or is something else responsible? I'm with Alan. If the long axis doesn't point toward Saturn, what does that say about Atlas's composition? |

We already know that Atlas is a pretty porous body (at least Pan definitely is). But certainly there has to be some explanation for current orientation, either through ring impacts or perterbation from Prometheus.
