Works for me, at least from work. At home it's been dead slow ever since they updated the site.

Here's the Jan 31st Titan observation:

Beautiful! Did you do some processing or is the lake really that clear on the raws?
ugordan
I did about the same kind of processing as for previous shots, couldn't find that thread to post it there, though.

Not sure if this'll work for you, but here are direct links to the raw images:

Nope, but your version will do me just fine in the meantime. smile.gif

Is it just me? For the last couple of days I haven't been able to view the most recent raw images.


I have to be honest, I'm really not a fan of the new look raw images site or format. It crawls at a snail's pace, and just doesn't seem as effecient to me. It's actually put me off visiting it.

I had the Cassini-Huygens home as my intitial page when starting up IE.

But the annoyingly slow "loading the player" has forced me to switch to something else.
(Did that drop their view count?)

I did fill out a feedback form. Hopefully if enough people comment, the website will improve.

Change for change's sake. All too common in cyberspace. Want to upgrade a site? Add more content. I use the Cassini site far less now than I did before.

And here's the earlier Kraken Mare view for comparison:

http://www.unmannedspaceflight.com/index.p...st&id=16065

I notice a small bright spot in the middle of the southerly bay in the new image. Is it real? Gordan (anybody) - does it appear in all three raws?

It's either absent or a lot less prominent in the older image.

Island, cloud or artifact?

It's a cosmic ray hit.

OK but I've just been digging for the original discovery image of the lake and that does appear to have a feature in the same position:

I wonder if we're talking about the same thing?

I'm finding it VERY slow to use too, but then my PC is over 8 years old. I have the RAW pages bookmarked, and go straight to them skipping the homepage. But even they seem a fair bit slower to navigate.

Apparently not, but anything faint and ambiguous you see in these enhanced, raw views is very suspect.

Actually yes! I've just tried the Cassini site again and was able to look at two of the three raws. (The third one 'opens' to reveal a couple of lines of random dialogue.) So now I can see that the cosmic ray is indeed the biggest contributor to what I was looking at - but it's still an interesting part of the lake that may not be totally 'blank' to ISS.


My reason for staring at marginally visible features within the lake is simple. There shouldn't be any! I'm not looking for changes, I'm looking for what stays the same. If some of the subtle features appear in the same place each time we view the lake then maybe they represent something real. Now while with SAR you can say we're seeing through the liquid to the lake bed beneath that shouldn't be so for the ISS images - unless the lake is very shallow, or indeed more of a mudflat.

However I'm not up to the job of taking the different Kraken views, reprojecting them and overlaying for direct comparison. What a pity . .

And same here - I was hoping to see images from yesterday's flyby of Rhea.

Many new images of Rhea available.
Bjorn Jonsson
And lots of interesting images of the F ring, including what's perhaps the most spectacular image I've ever seen of that ring:

http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=181948

Just WOW!
Sunspot
These direct links to Cassini RAW images no longer work for me, is anyone else having problems viewing them?
jamescanvin
Read a few posts back on this very thread, where we talked about this problem.

It seems intermittent. That link Bjorn posted worked for me this morning but it's gone again now.
Bjorn Jonsson
The direct link works for me but I'm posting the image here so everyone can have a look:

Thanks for posting the image. Wow, that IS spectacular. Surreal.

Just clicked on one of the latest batch of raw image thumbnails and got this message:

"Turn of a Narrow Ring","ISINSIDER":"0","STORYURL":"","ISFEATURED":"0","STORYI

What could that possibly mean?
elakdawalla
It's just some kind of database error. That site just hasn't been the same since their redesign.
lyford
Well, I would have gotten more excited if it said ""ALL THESE WORLDS ARE YOURS EXCEPT ENCELADUS..." laugh.gif

I have almost stopped looking at the raw JPGs after the redesign unless something particularly interesting is going on (e.g. the recent ring images). It's just too slow if you want to look at a lot of images and errors are too frequent. The only nice thing is that last time I checked links to the directories containing the images worked but they only contain the images - not the captions.

Here's my RGB version of the Titan crescent that's just appeared on the raw images page:

Stu,
I agree wholeheartedly.
This single image conveys a HUGE amount of information - It shows the Encke gap as part of Saturn's ring system (with associated ringlet), the Keeler gap, Prometheus and Atlas, Prometheus's gravitational effect on the F-ring, Prometheus's shadow across the f ring, cosmic ray hits, background stars, fine scale gradation within the A ring and so on. It's testament to the people that point the instruments on Cassini that they tease out the absolute maximum from every opportunity.
We are so privileged to be living in the era of a dedicated Saturn orbiter, and that the people that control it are so willing to share the raw data.

Now all we need are two more orbiters, one at Uranus and one at Neptune.....
Stu
Heck of a shadow... ohmy.gif

No new raw images since 10th July - one month before Saturn equinox. I'm assuming its an unfortunately timed summer vacation thing. Anybody know different?
volcanopele
Not sure what is up with that page. I can assure you that images have been taken and have been brought back to Earth.
ugordan
Several nice Janus shots from July 26 have appeared on the raw page, here's one false color IR3 + UV3 composite:

I had hoped this one was going to be spectacular, with Titan's shadow crossing the rings casting its shadow on Saturn:

The real raw image is quite dissappointing.. sad.gif

volcanopele
LOL, yeah, the observation may have been called TISATSHAD001... but, umm, yeah, the shadow is on the other side of Saturn at the time...

Regardless, these sequences have produced AWESOME images of Saturn. Already have Monday's as my desktop background.
Phil Stooke
Janus isn't disappointing, though - it shows the same kinds of albedo variation - irregular darkish patches - that we saw on Epimetheus in its closest images. No other small satellites show the same kinds of markings. On Hyperion, for instance, the dark spots are much more concentrated in low points.

Phil
ugordan
FWIW, I've also made a few Janus composites from PDS data some time ago. IR1/GRN/UV3 stuff, see here.

I swear it almost looks like giant impact basin sticking just over the terminator in the lower half of the image...probably a coincidence though.

Here's my shot at processing the Enceladus image - lotsa stuff got modified. (Full details on my flickr page here):

Magnified 2x. I figure there's a 60/40 chance the image is upside-down, with north pointing down.

(Cue Phil)
volcanopele
North is pretty much up. That view shows the leading hemisphere of Telesto, compared to previous observations that highlighted the trailing hemisphere.
ugordan
Some of the most prominent spoke displays I ever saw from Cassini came down.
http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=200348

Too bad the images are downsampled and horribly artifacted (short exposures?). They aren't visible in saturnlit portion of the rings, but the low sun angle on the evening side really brings them out nicely.
Bill Harris
The "spoke images" were pretty chunky, but have you seen the Ring shadow/Cassini (?) Gap display on Janus? N00141747 -55?
