Cassini-Huygens Reaches Orbit Around Saturn
Mick Ohrberg writes "The probe Cassini-Huygens is now officially in orbit around Saturn. Last nights' retro-burn was completed according to plan, down to the second, which in and of itself is an amazing feat, considering all data received is 1h24m old, as well as 900 million miles away. I must say, it was fairly exciting to watch the webcast, and see the signal fade behind the A-ring, and all but disappear behind the B-ring - all in (somewhat delayed) real-time. The SOI (Saturn Orbit Insertion) also saw Cassini-Huygens whisk by Saturn at around 68,000 mph at an altitude of about 12,000 miles from the cloud tops - the closest to the gas giant the probe will ever be during its planned 4-year mission, for instance the much awaited Huygens mission to Titan."

Not sure when the article was written but there are already raw and press images released as well as some others. The quality isn't as good as some may think and it really doens't show much detail into the rings at all.
Hmmm.
I can't believe that the data transfers over several billion miles in less than 2 hrs. I was wondering how long it might take, I was thinking more like a couple days.
San Francisco, California - Just three days after being the first in the world to leak photos of Apple's upcoming revision to MacOS X, version 10.4, Steve Jobs announced to the world facts about the new Operating System consistent with information leaked by elite GNAA operator Gary Niger and prospective member Ron Delsner.
"We've pulled it off!", noted Niger during Jobs' announcement at Apple's Worldwide Developers Conference. "The GNAA plan was clever from the start with this one I think. When we received our leaked copy of the OS, we knew that by releasing only partial information and some screenshots, the association people would make with the GNAA would lead them to believe the screenshots were fake. Now that Steve 'Rim' Jobs has verified everything we leaked, we have managed to fool the entire Mac community. In essense, a few hundred thousand people have been trolled, a few hundred thousand people have lost. Though I do wish they have a nice day"
"I don't think it could have worked out any better; Every single one of the features shown in our screenshots, particularly Dashboard, which everybody called as fake, was demoed by Jobs. This is my revenge for being beat up on the rent", quoted Ron Delsner on being approached by reporters. "I've been wanting to join the Gay Nigger Association of America for quite some time, and knew that I help pull off something big if they were to let me in."
Delsner was right, as upon hearing this, Gary Niger immediately produced a vial of what he called the "Holy Gay Nigger Seed" from his front pocket, and asked Ron to kneel, at which time the Seed was poured upon Ron's head, making him an official member of the GNAA. Noticing the television cameras present in the press room, Gary cited that this was in fact the first televised induction of a member into the GNAA.
"But back to the troll", Niger said quickly after. "I had a sneaking suspicion that the homosexual caucasians of the Mac community would feel threatened by the GNAA's massive nigger cocks and immediately cast doubts upon any screenshots we produced for them. I saw this as an opportunity to troll hundreds of thousands of people. It just goes to show that GNAA is greater than j00, and that fristage postage is mine."
And Niger certainly did not fail it, as can be seen from the following excerpts taken from various Internet website's covering the leak:
ThinkSecret.com - "In fact, it was the source that led many users to call the shots fake; the information in that story, as well as this one, was provided by Gary Niger and Ron Delsner of the GNAA, an organization that deals in crapfloods and Slashdot trolling."
AppleInsider.com - "Enjoy the photoshop work. I seriously don't think Apple would be so crazy to use those jargons."
MacRumors.com - "Hmm... Information by "Gary Niger" of GNAA. Sounds too stupid to be true. And that dashboard thing? Hogwash me thinks ..."
MacRumors.com - "I immediately thought of them when I saw "GNAA". Anyone who reads Slashdot would be familiar with them - they put big spam posts everywhere. Yes, and it doesn't surprise me. I don't think the screenshots are real (at least not the Dashboard ones), but I have no trouble believing the PDF."
Kim Kap Sol on AppleInsider.com said "I can guarantee those are fake." He then continued by saying "Hello I R Korea KEKEKEKE OMG ZERG RUSH GOGOGOGO ^_^"
Gary's reply to this was "Way to make a complete idiot of yourself you dog-eating douchebag."
Steve Jobs was unavailable for comment immediately following the keynote address, though WWDC attendee and GNAA member Porfa noticed "A cute wiggle in Jobs' ass as he walked away."
About Apple
Apple Computer is the creator of the Macintosh, popularly known as the "gay computer". 87% of GNAA members are Mac users. Founded in 1974 by Steve Jobs and Steve Wozniak, Apple was nearly out of business in the mid 90's, when Jobs was re

"It feels awfully good to be in orbit around the lord of the rings," said Charles Elachi, director of the Jet Propulsion Laboratory. "It's going to be a huge leap in our understanding of the Saturnian system.""This has just been an incredible ride," he said. "This wasn't NASA going into orbit around Saturn, it's the Earth going into orbit around Saturn because 17 countries made this happen. This is the way exploration should be done: by the Earth."
if only we could do more things like this
SHE does throw dice.
The worst terrorist attack in recorded history occurred just over two years ago, and you people are discussing a probe entering orbit around saturn? My *god*, people, GET SOME PRIORITIES!!!
I'm still amazed at the ability to work on delays like that. I get a little frusterated when remote controlled cars don't turn quite as fast as I expect them to. Think of all the planning involved... and be thankful that we haven't found any life on other planets/moons, cause that would really screw things up. Would the probe just smack into anything it came across? I certainly hope not. If so, I think some sort of technology that allowed some independent operation on the part of the probe might be a valuable investment for the next go-round.
Try and imagine this small piece of machine, an artificial eye, open to the wonders of our solar system, falling through the infinite depths of space, so that we can forget for a moment, all the troubles and tribulations around us, the cold steel and the raging fire and look beyond the physical confines of what makes us human and gaze in awe at this small contraption carrying a message of hope, of peace, of our thirst for knowledge in a never ending journey towards everything that is unknown.

It would be interesting to see how it looked like meanwhile it was in the ring system?
Or when it was nearby enough to see the massive amounts of rocks inside.
Or didn't it pass through the actual rings?
Beware: In C++, your friends can see your privates!
...but Jupiter is a more interesting planet.
Still, congrats to NASA -- anything that increases our knowledge of the universe while sending back beautiful pictures is worthwhile in my book.
Just like Huygens I'm Dutch, and thus I was taught a lot about him in school during the physics hours.
The biggest thing Huygens brought the physica is the 'Huygens source'. A simplified explanation: A Huygens source starts sending out sound (air vibration) because the source itself got vibrated by another source. So, a Huygens source doesn't 'create' sound, but simply relays it.
Of course this is really simplified and in reality it's fairly more complex.

The Cassini-Huygens spacecraft was launched from Cape Canaveral Air Station in Florida at 4:43 a.m. Eastern Daylight Time on October 15, 1997
I think they made pretty good time! Good thing I wasn't in the ship, cuz I'd be asking "Are we there yet?" every five minutes!!
The dangers of knowledge trigger emotional distress in human beings.
...I understand that the ESA-developed component of the mission -- the lander -- is due to touch down on Titan on Christmas day this year. Hmmm, sounds familiar. Wonder how that'll go.
:)
Will they never learn?
OK so I guess they'd've had to be quite foresighted to guess the events of Dec 25th 2003 seven years ago when they launched the thing.
These sigs are more interesting tha
considering all data received is 1h24m old, as well as 900 million miles away Recieving old data is easy. Receiving data that is 900 million miles away is very hard. The spacecraft is 900 million miles away. The data must be here, or we could not have received it. ;)
Could anyone buy these guys a FLAT projection screen ?
The interface for finding pictures is so difficult to use it has almost zero functionality. The interface looks intuitive, but when I do searches, I never get back what I asked for, especially when it involves dates. Those pictures are a big part of the mission for the general public, so I would think NASA would want to make it work seemlessly.

You know its really easy to take for granted the fact that in the last 50 years we have gone from a confined world to launching interplanetary probes billions of miles away. I think we are all a little desensitized from watching too much star trek/star wars and setting our expectations way too high. It really struck me this weekend when i was sitting on the beach with my girlfriend, relaxing and said "the cassini probe is going into orbit around saturn this week." She just smiled, because shes not that geeky, but really, never have humans ever been able to say something like that in matter-of-fact conversation. Now its the norm. Hooray for us:)

Show a kid a picture of the solar system and ask them which planet is their fav. It's Saturn. My 3 year old has already staked a claim to it. Then.. he's not trying to compensate for anything. :)
NASA and JPL did their job.
ESA better not screw up. This is the big one. Its the superbowl. You either put up or shut up. If you don't perform this time, better outsource space exploration to the russians or chinese.
This is a great day for science and I'm glad that we didn't give into the protesters back in 1997 (to prevent the mission) and 1999 (to stop Cassini from flying past Earth on its way back to Saturn after a gravity slingshot around Venus).
Although somebody has pointed out that they did qualify it as the closest approach during the 4-year planned mission, note that Galileo survived 6 years beyond its 2-year planned orbital mission, and sent back data even as they intentionally crashed it into Jupiter to keep if from possibly contaminating one of Jupiter's moons in the future. I wouldn't be surprised if a similar fate is in store for Cassini-Huygens: both a significantly extended mission, followed by a controlled "disposal" when its usefulness has been wrung dry.
I heard Carlos's comment on KTLA 5's morning news today. It was quite funny!

named after Giovanni Domenico Cassini
False. Everyone involved in the pursuit of emergency medical-care vehicles knows that NASA illegally named it after fashion designer Oleg Cassini to infringe on his intellectual property. The rings of Saturn clearly owe him royalties.
It's not several billion - it's only 900 million miles away, plus or minus 2 AUs or so. ;)
Cassini TRAVELED several billion miles to get there - its path looks like an archimedes spiral because of the multiple slingshot maneuvers it used to gain speed. This is also why it took so long to get there.

I don't know if those are gravitational waves you are seeing (They are building big machines to observe those, if you're the first to see one you got yourself a Nobel prize). The lines running oblique trough the image are obviously the rings of Saturn. The waves you are probably referring to run exactly horizontal. I therefore suspect it is an image artifact, caused by something in the CCD or because the image was recorded line for line. This might be a raw image, which still has to go through image processing to get the 'waves' out with some previous calibration. If it were something to do with the rings themselves than i would expect it to be either parallel or perpendicular to the rings, and not exactly parallel to the frame.

Most of our planet names come from the Latin form. Sometimes I see the Greek name used as the adjective. In this case it would be "Chronus", even more awkward.
M-W has you covered. Most astronomers I know pronounce it like "Hoi-gens" (hoi like in "a-hoy", gens with a hard g).
of course i wanted to write density waves :) my mistake. "Look at that structure, it's so regular!" marveled imaging team leader Carolyn Porco as a picture came in showing well-defined bands of brightness and darkness. "I'm wondering if we're looking at a density wave. This looks like it might be a density wave, but I'm not quite sure."
Density waves, caused by gravitational interactions with nearby moons, are thought to be "kissing cousins" of the waves that produce the spiral structure seen in galaxies like Earth's Milky Way.
"These are regions where the rings are communicating gravitationally with the moons exterior to them," Porco explained. A few moments later: "Oh my God, look at that! ... These density waves are like books, just waiting to be read."

SHE does throw dice.
I'm thinking he was talking about the interesting pattern of the rings. In the top left corner, there is one dark ring, with several "echo" rings getting weaker while they get closer to Saturn in decreasing intervals.
I agree with you on the horizontal lines, but there is obviously something in there that I can't see...some type of ripple. Here is an article talking all about the gravitational ripples.
http://www.msnbc.msn.com/id/5333700/
Now if it turns out they ARE talking about the horizontal lines, I'll die of hysterical laughter when they finally figure it out.
thanks the other poster for the correction. the article is here i just mistaken the words :)

nice image showing gravitonal waves in the rings (link)
Not sure what you mean by gravitational waves let alone gravitonal waves, but there does seem to be some interesting structure in the outer ring in that picture. It reminds me of the famous braided ring spotted by the Pioneer 11 fly-by. I don't remember if Voyager saw this kind of thing.
Here's a link to Huygens' Merriam-Webster Online entry, with sample sound file. Basically it's "HI-gens".
Yesterday I tried to post a Perl script that was (+5, Informative), if only the lameness filter had let me.
If you can pronounce Finnish (hey, it's a long shot, but anyway...), the correct pronounciation would be like "höijens", stressing the "j".
AM I RIGHT, FOLKS?
I understand that Cassini used gravitational assists to accelerate for the journey to Saturn. Does anybody know what maximum speed is attainable through these gravity assist maneuvers within our solar system? Just how fast could we make something go by doing a long series of these things with the most massive bodies in our solar system?
I must say, it was fairly exciting to watch the webcast, and see the signal fade behind the A-ring, and all but disappear behind the B-ring
Hmm, what happens when it gets to the O-Ring? ooooohhhhh ohhhhhh
For our next project, let's murder a bunch of foreigners.
This image shows all three imaging problems. There appears to be a short cosmic ray streak in the lower left quadrant veering about 30 degrees downward and to the right, there may be some speckle in the black band or it may be a real signal (the white dots in the black band) and there's banding throughout the entire image that spreads from the white regions to the black and back to the white.
What is that horizontal waviness in the picture?
There is a low level source of noise in the camera's signal as it comes out of the sensor and gets converted to numbers. This noise adds and subtracts a small amount to the signal in a cycle. When the data is put into an image, one can see it as bright and dark bands in the image. The amount of noise is very small and is not noticeable in most images. Images that are of black sky or very dark can show this noise. The camera records the baseline of the signal for each line so this noise can be removed in later processing. Both cameras are affected by this noise but the Narrow Angle Camera is worse.
It's cute that the one that was excepted had bad spelling in the title.
Nice try, but you mean ACCEPTED
If you are going to make a comment like this, please - for the love of god - use the proper word.

This space intentionally left (almost) blank.
Can anyone explain the seemingly horizontal waves that are running through all of the rings? They seem to be fairly uniform and direction and size. However, the orientation does not seem to be radial from the planet itself or any other object... Any conjecture out there as to what has caused this? They almost seem like an artifact in the images themselves.
Also, is anyone else a little disappointed that these are the best images we're going to get of the rings or are there going to be better pictures in the future? This is the closest the spacecraft is going to get to the rings, yet I really was hoping to see the individual components of the rings themselves. I've seen the intro to Voyager, and I wanted to see tumbling boulders...
Is Cassini the last of the billion-dollar deep-space probes? I don't see much else funded. Theres and on-again, off-again flyby to Pluto next decade. The Mercury probe Messenger was axed in the current White House budget. The next four launch-cycles to Mars are being worked on. But these are relatively inexpensive, small things in the couple hundred million range. Maybe a few more lunar and comet missions in the works too.
The previous NASA administrator Goldin promoted the faster-cheaper-smaller (and less reliable) probe model. I guess the initial Hubble troubles and the decade-long Galileo & Cassini projects spooked him out. At least Cassini will last for 4 to 10 years.

I don't know if this has already been mentioned, but there are 616,800 hand-written signatures from 81 countries on a disc inside Cassini. I remember when I was in 7th grade and my entire class sent in our signatures to NASA. Now it's seven years later and my name is billions of miles away in space. How cool is that?

I can't believe that the people on that website are real. They claim that NASA use RTG's and RHU's to cover up military plutonium launches. Where do they expect these probes to get power from?
I mean, seriously, I've seen some pretty crazy theories in my time, but this one takes the cake. Why would the military use NASA to cover up it's activities, how would this even work. Wouldn't the military still have to cover up their activities regardless of what NASA does?

...they passed through the ring plane, in the huge gap between the F and G rings.
Passing through the rings themselves would likely have been disastrous.
That's why cassini passed through the huge empty gap between the F and G rings.
In the denser rings, baseball-sized ring particles are about a meter or so apart. Most ring particles are much smaller than that though.
This is why the cassini radio transmissions were so strongly attenuated when it passed behind them -- the rings are dense enough to do that. If the ring particles really were km's apart, there would be virtually zero attenuation of the radio signal.
Had cassini passed through a ring instead of a gap, the mission would have been shortened rather dramatically.
