Wow, those are amazing. I didn't know that the smaller moons dipped in and out of the rings, perturbing as they went.

It's cool to see the gravitational wake left by the moons. I would have thought that all of the dust in the rings would have settled out to something more stable given the age of the system. is there an astrophysics person in the house that can explain why it hasn't?

Cassini is made by Aperture Science.

Saturn XXIII, thanks for bringing these into focus. They are truly spectacular, inspiring images - what a majestic phenomenon it is has the privilege of visiting (at least until the tourists show up).

From shot 16, Prometheus's elliptical orbit makes its path through the outer rings every orbit, creating streamers among the rings' dust and rocks.

Very cool photos.

Not to get all religious and all but this is why I believe in Heaven - because if I am a good little boy on Earth, when I die, God will give me wings and I will be able to fly around space discovering these wonderful things myself.

Oh, and I will have unlimited supply of ice-cold Pepsi, and those amazing artery-clogging frenchfries you can only get at souvlaki joints, and I won't need to go to the bathroom ever, AND I will be reunited with my cats.

The summer before my Dad died, he did some of the final safety inspections on Cassini's power plant so every time I see these kind of pictures it makes me happy that he had a chance to be a small part of something so cool and sad that he never got a chance to see the results. He bought a telescope for Halley's Comet and used to point out constellations to me so he'd be stoked by the amazing success of this mission. Thanks for the link.

Sometimes photos like this remind you of the actual reality of space. I've gone to some planetariums, looked through telescopes - and you get weirded out by how big and how real it is.
And looking at something like this, that is so achingly majestic and so vivid and real is awesome.
And then you come back to Earth, check out the web or t.v. or something and these stupid fucking monkeys are still killing people over crap that comes out of the ground.
I get what Wilde was saying, we're all in the gutter, but some of us are looking up at the stars.
I just hope it's enough of us. I see this and I don't think there's any question of where we belong. It's not fighting over bits of paper or symbols of status.

I may have missed it above, but I can't believe no one's linked this picture yet.

i prefer the natural color version myself...

also, that tshirt is cool and all (the image of io with jupiter was taken on the REAL millenium (jan 1, 2001), btw), but just so you know, i have an official 'cassini launch team' tshirt. its kermit green and has a tech drawing of the probe on the back. its ok with me if you'd like to seethe with jealousy. ;)

I would have thought that all of the dust in the rings would have settled out to something more stable given the age of the system.

well, firstly, the ring system might not be that old...possibly as young as a few hundred thousand years...shattered moon slowly re-accreting, etc etc. ...but mainly, its just a very dynamic system...the rings are being pulled on by 60+ moons. wanna know why the rings have all those crazy stripes? well, when one object orbits another and has negligible mass compared to the parent body (like a chunk of rock in the rings of saturn, or a manmade satellite orbiting the earth), then the equasions actually get quite simple and there becomes a direct relationship between the objects velocity, its altitude, and its period. here on earth, if you launch a satellite up to ~10,400 miles up, its period is 24 hours. (since the earth rotates every 24 hours, satellites at this altitude that orbit around the equator seem to hang in space, never moving...its called geosyncronous orbit) at the height of the space shuttle (~300 miles) the period is 90 minutes. ok, heres the cool part: imagine a moon that orbits saturn every 12 hours, and closer in, a ringlet that orbits every 6 hours. twice in its orbit that moon is going to be pulling every particle in that ring out of its orbit. this is what's known as a 1:2 resonance. a ringlet that obits every 4 hours would be in a 1:3 resonance. the cassini division (the big gap right in the middle of the rings) is caused by a 1:2 resonance with mimas. there are all sorts of resonances (2:3, 7:12, etc etc) between the rings and the moons...each moon (and remember, there's like 60 of them) basically leaves a very complex 'barcode' on the rings, the strength of the markings being due to the strength of the gravitional pull of the moon (that being determined by the moon's size and distance from the rings). also, some of the rings are spirals, going allll the way around saturn to become the next ring in, and some of the rings are bent slightly out of the plane of the rings by moons that orbit in inclined planes.

i am sooo looking forward to august, when the rings go edge-on to the sun. that one shot of the shadows cast by the big chunks at the outer edge of the B ring is just a hint of things to come...

also, i want to have sex with the cassini probe. *sigh* long-distance relationships are SO hard....

odinsdream, Electric Dragon,

If you want to get the actual raw images that the scientists use, they are released to the Planetary Data System (PDS) within one year of the date the image was taken. NASAView is a very basic program, available for PC, Mac, and Linux, that can display images in PDS format. If you want to get into this, I highly recommend going to UnmannedSpaceflight.com. A lot of very professional amateurs hang out there.

By the way, Cassini's two cameras only have 1 megapixel each!
posted by lukemeister at 7:32 PM on April 22, 2009


also, even easier, and linked above but not labelled, the cassini site has a raw images page. it's only b&w jpegs, but you can search by all kinds of criteria, or just hit 'browse latest 500 images' and see what saturn looked like yesterday. cassini is the first probe to release data so promptly (the 'one year' that lukemeister mentioned applies to the raw data...most other missions have this one year waiting period for all data...its to keep the scientists from getting 'scooped' on their discoveries). the fun crafts project is to look for a series of images on the thumbnails page of the same composition, but different shading...a good sign that multiple filters were used. on each images page the filters used are listed (CL1 and CL2 are the most common...both clear (each of the 2 cameras has 2 filter wheels with multiple filters on each wheel...all the filter acronyms are described here)). look for images taken with RED, GRN, and BL1 or BL2, and you can make your own full-color images in the photoshop. ITS FUN!

BONUS FUN: type 09/14/2006 thru 09/17/2006 into the search field. look familiar?

also, srsly, all i need is a saturn v rocket, some scuba tanks, and a big bag of trail mix...i could be there in a week...
