Are all of the images from Cassini being posted on the RAW website? The latest status report mentions mosaics of the rings:

"Science activities this week included optical remote sensing (ORS) scans of
Saturn's south pole as well as Ultraviolet Imaging Spectrograph mosaics of
Saturn's magnetosphere. Imaging Science Subsystem (ISS) performed mosaics
and movies of the rings and Saturn's south pole."

Can any Cassini insiders here shed any light on this?

From Cassini's RAW website:

"The Cassini raw image processing system is being upgraded. During this period, the spacecraft will continue to take data and images. The upgrade process will be completed by Sept. 3. Once the upgrade is complete, all raw images received during this period will be available on the web. "

I wonder if they are adding the RAW data from earlier in the mission. I can't wait to see the images of Jupiter

I haven't heard anything but I am hoping that the way the images are stretched will be changed.

Posted by: Sunspot Sep 3 2004, 10:31 AM

The latest RAW images are being added to the website, but I dont see any diference to it or the images.

Posted by: volcanopele Sep 3 2004, 06:38 PM

yeah, I just looked at them too. For me it's not that big of a deal, but I can understand if others out there are frustrated with JPL.

This is my little contribution for the Unmanned Spaceflight community.

New software dedicated for fast preview Cassini's Raw Images Archive
(Coiss_2001 to Coiss_2025 volumes)

I have problem with auto stretch, I hope next version will be better.

OK, please review the attached program.

Posted by: ugordan Aug 21 2007, 07:40 PM

Wow, this is real neat.
I was planning on doing something similar that would also feature calibration ability, but was too lazy to ever do anything about it.

Great work, this will come in handy when browsing the cryptic image filenames! One thing I do with my image filenames upon calibration is include filter combo and 2 letter acronym of the target for quick navigation, it might be useful if you could do something similar in the image title bar - just to help quickly identify what you're looking at.

This newer version of CassiniView, originally dedicated for
Coiss_2001 to Coiss_2025 volumes (Data from Saturn Approach
to End of Mission), was adjusted for properly work with
Coiss_1001 to Coiss_1009 volumes (Cruise and Jupiter Encounter Data).

Additionally "target name" was added after "file name" on top
of open window for better orientation.

Greetings,

I was getting some errors on the Cassini Raw Images page when attempting to call up the Dione Narrow Angle images from 9/30/2007. I wonder if anyone else is seeing such errors?

Thanks,

Steve

Yes I was getting stuff like that when I was looking for the latest Janus images yesterday.

Posted by: jasedm Mar 3 2008, 04:31 PM

It seems the raw images pages are subject to problems again, with the same error message noted by Steve when attempting an image search.
This is such a wonderful facility, it's easy to take it for granted and get a bit impatient when it's offline. Nothing for a week or so now....I'm eagerly awaiting the NAC scan of the Maxwell gap area from yesterday's periapse observations.
........must learn patience.....

Posted by: OWW Mar 3 2008, 05:03 PM

It's not only the raw images page that's broken. What's up with the "Where's Cassini now" page? Lately it's been showing Cassini's position on January 21th....every day. I'd love to see the PRESENT position during the upcoming Enceladus flyby.

Posted by: jasedm Mar 5 2008, 02:38 PM

Raw images now fixed, but present position still stuck stubbornly on 21st January..

Posted by: jasedm Jun 16 2008, 06:40 PM

Some raws from 9th June appeared today (NAC ring images) which were taken during periapse last week.
http://saturn.jpl.nasa.gov/multimedia/images/raw/raw-images-list.cfm?StartRow=1&cacheQ=1&browseLatest=1&storedQ=1668421
There are data missing from this batch of raws represented by horizontal gaps/lines in the images - does anyone know what causes this intermittent problem? (the lines have appeared on a small percentage of earlier images)
Is it a software issue, or camera scanning, or data recorder issues, or problems with DSN reception of the data??
These have appeared later than they normally would, which would seem to indicate a problem getting them down - just curious.....

Posted by: volcanopele Jun 16 2008, 07:28 PM

Usually these are caused by DSN data dropouts or errors in transmitting the data from DSN to JPL. These images are tagged as preliminary in the hope that those gaps will be filled by more data coming down the pipeline, either from the DSN or by another pass through the Cassini SSR (though the latter is only done for high priority data). After a week, if those prelim images haven't been fixed, they are changed to final images, which allows their release on the JPL raw images page.

Posted by: jasedm Jun 17 2008, 01:30 PM

Thanks VP for that very clear explanation.
Had these been near-encounter Enceladus images then (for example), the likelihood is that the contents of the SSR would have been re-transmitted on another DSN pass.

Posted by: peter59 Jun 23 2008, 03:33 PM

The analysis of these unusual images may help to determine vertical structure of Saturn's clouds. High clouds are clearly visible on Saturn's nightside

Are those 'blobs' like thunderheads sticking up above the dark hemisphere, or are we seeing buoyant gas balls off the limb ??

Freaky strange pictures either way. Doesn't look like comparable Voyager Neptune shot at all.

Posted by: scalbers Jun 23 2008, 05:23 PM

Perhaps these are slightly higher clouds that catch the light better as we progress across the terminator? This type of thing would happen with high cirrus or cumulonimbus clouds on earth in twilight.

No new images from Cassini on the website since September 20 (A few from August posted since). I assume the problem is with the Cassini website and not the space craft. Anyone know what's up? We have the next Enceladus in 12 days.

Posted by: rlorenz Sep 27 2008, 06:43 PM

Conjunction was earlier this month

Posted by: jasedm Sep 28 2008, 12:17 PM

There has been at least one downlink since conjunction (probably more). Perhaps the webmaster is on holiday???

Posted by: Floyd Sep 28 2008, 03:06 PM

Conjunction was Sept 1-7 and there were zero pictures on cassini site if you search 09/02/2008- 09/07/2008. Every day since then we have between 1 and 202 images, 09/20/2008-09/21/2008 = 43 images. From 09/21/2008 through 09/28/2008=Zero. Webmaster holiday may be the cause.
I sent an e-mail today to the Cassini Contact Us, but it may get fixed faster if someone from the Cassini team contacts the webmaster.

[Edit] Got the meaningless auto reply thanking me for my e-mail

Posted by: ngunn Sep 28 2008, 04:28 PM

I wonder which will turn up first - the raw image containing Kraken Mare or a processed version?

Posted by: rlorenz Sep 29 2008, 01:05 AM

I confronted a similar problem recently having to download 3000-odd Pioneer Venus
ephemeris files (created when 45K/orbit was a big deal, I guess)

I found a downloadable PC program called Getbot (and I am sure there are many others
with similar capability, maybe there are some that are free) that was $20 and works well.
You can select a load of files if under the same directory, or you can paste in a list of
urls and it will hit them in sequence.

(I used an IDL script to generate my list of files as a text file, as they were spread
across 68 directories [corresponding to 68 CD-ROMs) in a rather uneven way
- 40 orbits on one, 200 on another, etc. so I had to use a for-next loop with custom limits
for each CD rom..... huge pain, but beat the heck out of right-clicking 3000 times and waiting..)

Posted by: jasedm Sep 29 2008, 12:59 PM

I'm looking forward to the Tethys observations (range between ~110,000 and ~160,000km). The earlier of these will show similar terrain to the best global views achieved by Voyager 2 (Telemachus, Ajax, Polyphemus, Phemius etc) - it will be intersting to compare the differing qualities of the NAC optics of the two craft.

Posted by: scalbers Sep 29 2008, 03:03 PM

Perhaps we'll see an improvement in resolution over previous imagery (combined Voyager/Cassini) in an area north of Telemachus, though it would be near the terminator.

Posted by: ngunn Sep 29 2008, 09:38 PM

Well, we seem to have some new raw images now, including the Kraken Mare ones.

http://saturn.jpl.nasa.gov/multimedia/images/raw/casJPGFullS44/N00120322.jpg

Posted by: elakdawalla Sep 29 2008, 09:54 PM

Yes. Use http://www.gnu.org/software/wget/ (which is also what the Imaging Node wants you to use to grab files from their servers). Use the scripting language or software of your choice to generate a plain text file containing the sequential URLs, one per line (I use Excel for this, since I'm not much of a programmer). Then go to a command prompt and type



Where "list.txt" is the name of your text file containing the list of filenames.

But that's actually a harder way to do it than the following. Wget is really designed to grab whole folders (even whole websites). Give the following command line a shot:


That grabs every image in the casJPGFullS44 folder...I just got all 1267 images in 2 minutes. Pick out whichever sequences you want from that folder. Wget is my friend!!

No new images at the raw images page this week. Hopefully everything is OK though - on November 24 Cassini was supposed to obtain stereo coverage of Tethys' southern hemisphere that I was interested in seeing (DEMs are fun!).

Posted by: scalbers Nov 28 2008, 08:02 PM

Yes, I'm also hoping the page will be up so we can see the non-targeted Enceladus flyby on Dec 2.

Posted by: tedstryk Nov 29 2008, 04:29 AM

With the Thanksgiving holiday this week, if the raw page has a problem, there is a good chance no one is around to fix it.

Posted by: jasedm Dec 2 2008, 01:18 PM

As noted on other threads, there are some raw images now available from the last periapse pass, but there are big gaps in the image numbering.
There are for example no frames between N00124458 (a single Helene Image) and N000124650 (Mimas in front of Saturn's disc) The 'missing' frames would I imagine include further Helene shots with different filters, and the Tethys south polar stereo images - I hope the data wasn't lost
The lone Helene image is taken gazing down into the large polar crater - see below enlarged, sharpened and enhanced.

Posted by: angel1801 Dec 3 2008, 09:57 AM

All of the Tethys, Helene and Enceladus images are now viewable on the raw image gallery.

Posted by: jasedm Dec 3 2008, 06:09 PM

Looks like the targeting of Helene was just a tiny bit off (the moon appears at the very edge of the NAC FOV in most of the raws from the latest flyby) - I wonder how much this is due to the moon 'wandering' from it's Lagrange point due to unaccounted-for perturbations by other objects?
It seems a portion of Cassini's time in most of the revolutions include 'orbit determination' images of the rocks - now we can see why this is important.
Perhaps this was why the planned images of Pallene a couple of orbits back didn't materialise...

THe picture next to it of Tethys isn't bad either:

http://saturn.jpl.nasa.gov/photos/raw/rawimagedetails/index.cfm?imageID=180739

Posted by: pat Jan 25 2009, 09:37 PM

In this case the problem was with the spacecraft ephemeris used when calculating the camera pointing. There was an OTM between the time the camera pointing was calculated and the time it was uploaded to the spacecraft. The new post OTM ephemeris was only released shortly before the instructions for the sequence were sent to Cassini. The new trajectory was different enough that when combined with the out of date pointing it put Helene near the edge/partially off the NAC frame. The ephemeris for Helene is accurate, it was where it was expected to be -- its Cassini that wasn't where it was expected to be.

A similar situation applied for the Pallene images. On top of that it turned out that Pallene was also in Saturn's shadow at the time the images were taken, something that was overlooked when the observation was planned -- so even if the camera pointing had been updated with the latest spacecraft ephemeris we wouldn't have seen anything.

Posted by: volcanopele Jan 25 2009, 09:37 PM

According to the Looking Ahead article for Rev101:

http://ciclops.org/view/5461/Rev_101

That's Beta Crucis (or Mimosa).

Posted by: ngunn Feb 3 2009, 10:19 AM

Is it just me? For the last couple of days I haven't been able to view the most recent raw images. The thumbnails are blank except for the image numbers and attempts to open the full res versions are redirected to the site feedback form (which I have completed and sent).

I particularly wanted to see the latest Kraken Mare shots. If anybody does have them could they please post a specimen in a suitable thread?

Not just you - I've been having the same problem.

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

Posted by: ugordan Feb 3 2009, 01:06 PM

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:

Posted by: ngunn Feb 3 2009, 01:28 PM

Beautiful! Did you do some processing or is the lake really that clear on the raws?

Posted by: ugordan Feb 3 2009, 02:05 PM

I did about the same kind of processing as for previous shots, couldn't find that thread to post it there, though.

Posted by: Stu Feb 3 2009, 02:44 PM

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.

Posted by: Juramike Feb 3 2009, 03:22 PM

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.

Posted by: Phil Stooke Feb 3 2009, 04:38 PM

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.

Posted by: ngunn Feb 3 2009, 04:57 PM

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

http://www.unmannedspaceflight.com/index.php?act=attach&type=post&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?

Posted by: ugordan Feb 3 2009, 05:02 PM

It's a cosmic ray hit.

Posted by: ngunn Feb 3 2009, 05:23 PM

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:
http://www.unmannedspaceflight.com/index.php?act=attach&type=post&id=9505

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

Posted by: Sunspot Feb 3 2009, 06:43 PM

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.

Posted by: ugordan Feb 3 2009, 06:46 PM

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

Posted by: ngunn Feb 3 2009, 07:21 PM

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 . .

Posted by: peter59 Feb 5 2009, 12:44 AM

Posted by: Bjorn Jonsson Apr 16 2009, 08:30 PM

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.

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.....

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.

Posted by: Phil Stooke Aug 5 2009, 09:17 PM

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

Posted by: ugordan Aug 5 2009, 09:24 PM

FWIW, I've also made a few Janus composites from PDS data some time ago. IR1/GRN/UV3 stuff, see http://www.flickr.com/photos/ugordan/3373668632/.

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.

Posted by: Bill Harris Aug 30 2009, 09:16 PM

The "spoke images" were pretty chunky, but have you seen the Ring shadow/Cassini (?) Gap display on Janus? N00141747 -55?

Posted by: jasedm Aug 31 2009, 07:19 AM

Wow! That is quite something to behold Bill!
I would guess that's sunlight piercing the Encke gap and traversing Janus, rather than the Cassini division which isn't really a gap.
This is like a Cassini updating of the F ring shadow traversing Epimetheus which was captured fortuitously by one of the Voyagers all those years back.

Very cool.

Posted by: Bill Harris Aug 31 2009, 10:54 AM

You may very well be right; Cassini "Gap" is a mis-nomer, and that division is far too wide to produce an anti-shadow this narrow. I was probably thinking "a" gap and not a specific Gap. Look at the nature of the beast: you see sharp edge, narrow ringlet, then wide-diffuse edge. This made me think "generic Cassini", but it could easily be the Keeler, Enke or (here we go again) the Huygens Gap.

Those with ephemerides and Celestia can figure out the details, I'm just reportin' the news...

Posted by: Bill Harris Sep 1 2009, 07:34 PM

This has to be from sunlight filtering through the Cassini Division.

Quick calculations, assuming a ring plane-to-Sun angle of 0.3 deg and a shaft-of-light width of 193 km (max. diam. of Janus) I get a gap width of some 36,000 km, which matches most closely to the Cassini Division. The widest gap, the Enke Gap, gives a shadow width of only 1.7 km, far too small. Also assumes an "infinitely distant point source" for the sunlight, so no penumbral effects.

Posted by: elakdawalla Sep 10 2009, 02:37 AM

Cool. The spokes are about as obvious here as they were to Voyager. Clearly there's a seasonal effect, but last time I talked to rings people about this (which was a couple years ago) opinions were divided on whether it was simply seasonal lighting conditions or that there was actually seasonality to the phenomenon of spoke formation (or maybe even both are in play). Anybody know what the status of that argument is?

Nice to see this sequence as well. I've been experimenting with the Sept 13 sequence in my map and will try the same with this one. They may add a bit of coverage at slightly better resolution. They (along with a look at the official map) are helping to suggest some positional improvements in the Seville Mons and "Snowman" crater areas (generally the Saturnshine imagery).

Time to totally blow your minds!!!

I was looking through a 159 frame set of images that showed a tiny portion of Saturn's sunlit limb.
There were lots of streaks in the images and at first I thought it was just cosmic ray strikes, but they were too regular and moved in a constant stream throughout the 159 frames. I animated them and they certainly looked very cool....but then...!

I did a gamma enhancement on the images and in the background something amazing caught my eye.... SATURN'S AURORA!!!

OMG!!! In full motion!!! Incredible.

The full file it too big to post here, so I've put a cropped version on my blog http://astro0.wordpress.com/files/2009/10/saturn_streaks_crop1.gif (Warning 3.62mb)
EDIT: Full version http://astro0.wordpress.com/files/2009/10/saturn_streaks_lge1.gif (Warning 9.83mb)

PS: If someone has an explanation for the consistency of the streaks I'd be grateful.
Mystery solved (see post below)!

EDIT: Relinked the above images to versions rotated 180 degrees. It all makes much more sense.

Posted by: Reckless Oct 12 2009, 11:12 PM

OMG Indeed that is spectacular.
Very well done Astro0

Posted by: nprev Oct 12 2009, 11:13 PM

..Show my mind blown!

What's the interval between those frames, Astro0? Those streaks look almost like co-rotating particles (exhaust condensates hanging around Cassini?) The aurorae are megacool, of course!

Posted by: helvick Oct 12 2009, 11:16 PM

Absolutely amazing. I'm also curious about the streaks vs the static points - are they background stars while the static points are just noisier pixels, or are they just imaging\processing artefacts??

Posted by: Stu Oct 12 2009, 11:20 PM

Holy frak...

I went to bed last night after scanning the Kepler field of view through my binoculars, and sensing countless 'alien Earths' were within it... I got up this morning to see new images of a billions of years old meteorite sitting on the dusty plains of Mars... now I'm going to bed having seen the aurora of the Lord of The Rings fluttering and flapping on my screen...

We are all truly blessed to be here at this time.

Congratulations Astro0, that sequence will probably go global tomorrow.

Posted by: Juramike Oct 13 2009, 02:03 AM

Wow!

Nice catch! That is outstanding!!

-Mike

Posted by: Astro0 Oct 13 2009, 02:28 AM

OK Emily solved the mystery of the streaks for me (and helvick had the idea right too).
Rotate the image 180 degrees...kind of a D'oh! moment....sort of the 'mound becomes a crater' when viewed upsidedown

The streaks are not in the foreground, they are the background stars.
The aurora makes way more sense rotating around the planet (I've highlighted the horizon).

That's got to be one of the best movies from Cassini, ever! I can't wait to see what it looks like with calibrated data, without the hot pixels and jpeg artifacts. Great find, Astro0!

The aurora seems to rotate, I wonder if its due to Saturn's rotation or if it's connected to orbital motion of one of the moons?

Posted by: Floyd Oct 13 2009, 04:09 PM

They could also be looking for moons. There may be one or more moving at a slightly different direction than the hord of background stars. Really interesting.

Posted by: ngunn Oct 13 2009, 08:53 PM

Anecdote: My daughter just 'phoned' via computer from Germany and as we spoke I directed her to the aurora animation. She was very impressed. Just one more to add to the number. Well done all concerned!

Posted by: Phil Stooke Oct 13 2009, 09:04 PM

"They could also be looking for moons"

Surely this would be the worst possible geometry for looking for moons! Most of the frame is the planet, tons of noise and any moons are thin crescents, hence very faint. So not very likely.

Posted by: ngunn Oct 16 2009, 10:03 PM

Beautiful image.

I've taken to wondering what a ring plane crossing would look like from one of Saturn's moons. It's not inconcievable to imagine an Enceladus orbiter at some future date. I'm looking at a table where the orbital inclination of Enceladus is given as 0.02 degrees. Would the rings really disappear? For how long? A few seconds, minutes or hours? Would there be a magic moment when the only visible features are F ring perturbations, Daphnis wake and other vertical protuberances?

EDIT: If that Enceladus orbiter were in a polar orbit it would presumably make the ring plane crossing many times for each time that (the centre of) Enceladus itself did so. Could this provide a significant secondary imaging objective for such a mission?

My take is that's an image beyond Saturn's terminator, with rings still receiving sunlight. North is to the left and the northern hemisphere receives reflected ringshine. In other words, a looong exposure image.

It's part of that animation of Tethys, Prometheus, and Pandora -- there's a jump in the animation where there was a frame missing. When images appear on the raw site late like this one does, it's usually because there was an issue with the data and they were trying to get it retransmitted from the spacecraft. At some point, the spacecraft's recorders are emptied in preparation for the next sequence, and they have to give up on getting the full image back; at that point the best version they have gets posted to the raw site.

Nice but its Rhea, from the Looking Ahead article:

Finally, the third mutual event is an occultation of Rhea by Titan when Saturn's largest moon is 1.01 million kilometers (630,000 miles) away and Rhea is 2.3 million kilometers (1.5 million miles) away.

Seriously I write these things pretty much for you guys...

Posted by: ugordan Oct 30 2009, 05:54 PM

Ahh, it figures... The terminator did look too rough for Dione. I originally thought it might be Tethys, but it didn't fit so I just went with http://space.jpl.nasa.gov/cgi-bin/wspace?tbody=606&vbody=-82&month=10&day=27&year=2009&hour=15&minute=27&rfov=60&fovmul=-1&bfov=50&porbs=1&showsc=1. I guess the color is all wrong for http://space.jpl.nasa.gov/cgi-bin/wspace?tbody=606&vbody=-82&month=10&day=27&year=2009&hour=19&minute=31&rfov=60&fovmul=-1&bfov=50&porbs=1&showsc=1, then.

As for the Looking Ahead, most of the time I've come to prefer being surprised by cool shots and observations here and there rather than reading about them in advance and impatiently expecting them, only to be disappointed half the time (I'm exaggerating obviously) by unplanned data losses and dropouts.

Remember the dark old days when you needed a subscription to Sky & Telescope (and the ill fated Star & Sky which burned me 2 years out of a subscription) when you might get a spacecraft image 6 weeks after the fact. Then, 30 years later, having this wonderful community unleashed with the raw data doing its own miracles, we are truly blessed. We live in an exciting age of exploration. Not to mention instant gratification.

Wow; you can even see the fuzzy edges of the shadow from Titan's "ring effect'!

Posted by: ngunn Nov 8 2009, 10:57 PM

Not sure about that. I did a rough calculation and satisfied myself that the fuzziness is mostly accounted for by the angular diameter of the Sun, the distance of Titan from Saturn and the oblique projection of the shadow on the planet. That's very tentative though and I'd welcome evidence to prove that the shadow is actually more fuzzy because Titan is.

Is this dark object a moon and if so, which one?

The bright point below obviously is a moon crescent, but this object shows no sunlit crescent even though this is obviously a very long exposure. Moon in eclipse? It's not a camera artifact as it moves between 3 frames and is motion-blurred in the blue frame, consistent with orbital motion.

The RGB composite above is from an http://saturn.jpl.nasa.gov/photos/raw/rawimagedetails/index.cfm?imageID=206240. Also, I thought the ring was much thicker, it looks pretty compressed above.

--Bill

Posted by: ugordan Nov 14 2009, 10:22 PM

Yes.

Posted by: nprev Nov 15 2009, 12:17 AM

That almost looks like a shadow of a moon rather than the object itself. Any idea what the solar illumination angle with respect to it is?

Posted by: ugordan Nov 15 2009, 12:51 AM

I don't think it can be a moon shadow, Nick. The phase angle at the time was around 107 degrees and Cassini was 2.4 million kilometers away from Saturn. That http://space.jpl.nasa.gov/cgi-bin/wspace?tbody=699&vbody=-82&month=11&day=11&year=2009&hour=23&minute=30&rfov=60&fovmul=-1&bfov=30&porbs=0&showsc=1 isn't too favorable for diffuse ring viewing, but it does provide for a significant shadowed region around the right ring ansa (which I believe was the one imaged). For a point-like moon shadow, the sun would have to be behind Cassini.

Posted by: nprev Nov 15 2009, 01:06 AM

Well, that was my best guess! I have no idea.

It's a bit large for an artifact; were there any other images taken of this field at this time?

Posted by: Bill Harris Nov 15 2009, 02:20 AM

Looking at W00061219 and -6127 (much deeper exposures, CL1-CL2 filters) as a "brightfield" exposure, you can see some dead pixels but not in the area of Object X. So it is not in the camera.

I'm stumped. Maybe a cloaked Deathstar? I wonder, also, if those "comet-like" streamers in the deep exposures are real or internal reflections? Don't recall seeing them elsewhere.

--Bill

Posted by: charborob Nov 15 2009, 04:05 AM

Nice image. Not sure which moons these are. Interesting note: the Saturnshine on the small one is brighter than on the other one. Must be closer to Saturn. I upsampled the image to almost twice the original size. JPEG artifacts are a bit of a nuisance around the limbs.

Wonderful - I was really, really hoping you'd do that with the 'Hyperion rising' one. Incidentally on the other image I'm seeing a bean-shaped black blob around Hyperion, apparently silhouetted against the rest of the scene. I presume that's crept in when you were stacking images.

Posted by: ugordan Nov 15 2009, 06:44 PM

Yep, that would be the source, separate background subtraction for the base and Hyperion images. It's not readily apparent to me though, I have to really look hard to notice it, that's why it escaped me. How bright is your monitor setting?

I wouldn't say that. I'm not tired of looking at our own Moon. I like to see it rise, I contemplate its phases. Its a natural: each time I go outside, night or day, I look around to see if the Moon is there. Throw in a couple of other moons, and you would get a never-ending spectacle.

Posted by: ugordan Nov 20 2009, 08:45 PM

It's possible to stack a few frames and enlarge, but with the raw jpegs it doesn't really do much. Here's a 150% size stack of blue frames centered on Titan to improve limb details below Rhea (being blue frames they really mess up the north polar hood so that's untouched) and a stack of green frames to improve details on Rhea. Color is from the first composite. Not much of an improvement.


One could do this registration with complete color sets to further improve s/n and color, but it's a lot of work and I'll let someone else pitch in.

Posted by: ngunn Nov 24 2009, 10:09 PM

I notice they've used an orange tint to highlight the aurora. That got me thinking: What colour are Saturn's aurorae, actually? I would have expected them to choose green if they wanted to add colour to the movie - except that the colour of terrestrial aurorae is down to oxygen and nitrogen mostly and they are in short supply on Saturn. Ionised hydrogen glows red, so maybe orange aurorae for Saturn is about right after all. Anybody know?

I think the spherical moon is Tethys. It's gotta be close to the planet, and its not as bumpy as Mimas. That leaves Enceladus, and Tethys (Dione is a bit far away). The moon seems uniformly cratered, excluding Enceladus.

So my guess is Tethys.

Posted by: charborob Nov 27 2009, 01:59 PM

According to the CICLOPS site, it should be Rhea.

"On November 24, ISS will image two transits by the co-orbital moons Janus and Epimetheus across the disk of Rhea.» (http://ciclops.org/view/5969/Rev121)

By the way, Cassini has taken many images of this event. It would be interesting to make an animation. I may not have the time myself to do it today. Maybe someone else can give it a go?

I have animated this sequence too. Please see the attached .mov for an animation of the storm. The storm traverses the image from left to right. the limb of the planet and starfield beyond are visible in the lower right hand corner.

I had the same problem. I did my own version and it seemed to choke on the file which wasn't really that big.

For those of you who use the Rings Node Saturn Viewer to figure out which moons are which in these images, they just updated the ephemerides, and Pandora is now in the correct location in their simulated views -- it was off for a while. Not sure why that was.

Hi

This is my first post. Some links below to some great pics of Titan, a moon and rings I found recently on the Cassini raw images page which I haven't seen here yet.

Thanks to Doug and the Admin team for creating and maintaing this great forum and to all the forum members who've greated and posted the incredible picutures from various missions. Thanks also to the people running behind these missions for their work in getting these images taken in the first place.

Cheers

Simon

Neat images! Is it just me or is the limb on Titan's night side visible?

Posted by: Stu Dec 6 2009, 07:23 AM

Just... wow...

BTW, welcome to UMSF, nomisn!

Thanks Stu. Wow indeed. I've been saying this quite a bit recently in regards to all these great images coming down from Cassini.

I've been following this forum for quite awhile but when I saw some of these Titan images coming down recently, I had to post the links. This pics are incredible and credit has to go to the Cassini team (and and the MER team) for making these raw images available online so quickly. BTW Stu thanks for the great pics you put up also here and on your sites. They're great too.

In looking again at the photo link I posted previously , it does look like the limb on night side of Titan is visible however I'll be interested to see what others think on this as to whether it is visible or not.

Thanks for highlight, Stu! This is spectacular too:

Note also last Titan eclipse images, here the W00061875 with, on the right, two Narrow Field enlarged pictures with removed artifacts (deinterlace and hot pixel; images N00147830 and N00147832):

It's very clear on my monitor.

Others will do much better, I'm sure, but I just fancied a go!

And here's a colorization of that Titan-Mimas mutual as well:

Sorry, Gordan, that one slipped by me. Hard to keep up sometimes!

Posted by: dilo Dec 6 2009, 01:27 PM

I missed too ugordan post... anyway, this is my color version, based on the RGB triplet N00147406+407+402:

Here's a colorization of an old, calibrated CB3 filter image, N1525952199_1.IMG:

Too bad there's a general paucity of such shots showing both Titan and Saturn in the same frame, let alone full color sets.

Posted by: scalbers Dec 6 2009, 03:22 PM

That's pretty spectacular Gordan - with the rings, crescent Titan, and atmospheres all there.

Posted by: Stu Dec 6 2009, 04:22 PM

That is truly stunning, thank you.

Just missing an 'Enterprise" in the foreground and it would be perfect!

Posted by: ugordan Dec 6 2009, 04:26 PM

I'm leaving that up to others who are better versed at compositing mechanical objects into an image!

Posted by: nomisn Dec 7 2009, 08:12 AM

Thanks ugordon for the colorization of the Titan-Mimas mutual. Spectacular!

Another view of a crescent Saturn; this time from the 5th December:
