Still can't get on the raw images site... has anyone ever known a lock-out like this before? I can't remember having this much trouble getting at the Iapetus close fly-by images...

It's unusual. I've exchanged emails with folks at JPL and they are working on the problem. They say that although it seems as though it's traffic-related, they've tested with much higher demand and not had problems, so it's a bit of a stumper.
FWIW, I do get pages to appear as long as I wait long enough. --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

I thought some of the rough images would make a cool animation
especially (oddly enough) because of the motion blurry frames.

mgrodzki, I think you need to run that backwards, I'm pretty sure this is the south polar departure view.
Cool website BTW. Astro0 |

Hi all,
New member here - fist post :) I made some colour composites of Cassini's raw images. You can see a hint of blue inside some the northern craters. It becomes more obvious when the image is oversaturated in a imageviewing/manipulation program. Enceladus' north pole seen from ~91000 km. Filters IR3, GRN, UV3 mapped to R, G and B. Distance about 91000 km. Raw-images: N00103753 - 55 The north pole closer - from about 65000 km. Filters IR3, GRN, UV3, CL mapped to R, G, B and luminosity. Distance about 65000 km. Raw-images: N00103763 - 66 South pole area and some tiger stripes seen from about 130000 km. Filters IR3, GRN, UV3, CL -> RGB+lum. Distance about 130000 km Raw-images: N00103775 - 78 I also compiled a flyby-video using the raw images, it's in Youtube: http://www.youtube.com/watch?v=l5PqLPU2VA4 Yay, first post! Spin0 |

Thanks for those spin0, and welcome.
It's useful to see the colour composites as they show the fresher ice more clearly in various features. I liked your Iapetus flyby composite on youtube too - shows very well the frenetic activity of the cameras during that relatively slow flyby. |

Welcome, spin0!
Great color images (I tried to make something similar with UV+Clean+IR of South Pole view, but your results are better!). I suspect that blue/green features are actually SHADOWs of the plume, based on their position respect to tiger stripes fractures. Any opinion on this? PS: mgrodzki, your animations are stunning, bravo! -------------------- I always think before posting! - Marco -

I suspect that blue/green features are actually SHADOWs of the plume, based on their position respect to tiger stripes fractures. Any opinion on this? I have to disagree. It's the coarse ice within the fractures that has a different spectra (notably it's dark in the IR3 deep infrared filter, not particularly so in the IR1 filter) making them blue-green. The plumes are far too dilute to produce any shadowing, in fact they pretty much only scatter light, not block it. Notice there are blue-green fractures to the left as well, far from the pole where the outgassing happens. BTW, nice work on color registration, Spin0! I think it's funny how the raw contrast stretch algorithm makes it appear Enceladus was illuminated with the usual "white" light from the Sun when in fact the light coming through was pretty yellow/brownish, depending on how much of the illumination is directly due to reflected ringshine. In particular, both the rings and Saturn are dark in the UV3 filter indicating the exposure required was long. And yet, no obvious blur can be seen in the narrow angle. Amazing. -------------------- |

I like the departure/arrival movies! Reminds me of a Fritz Lang movie. German Expressionism meets space exploration.

Hmm I knew the CDA glitch would be focus of any post flyby news coverage.
Cassini probe failed to taste moons geysers in flyby |
