Hello, new to this site at the invitation of Carolyn Porco. Looking at the interesting discussion and one area that I can comment on is the methane. While it is true that methane can form as a breakdown product of organics at high temperature it can also be formed biologically. It is interesting that the microbial ecosystem on Earth that is my favorite candidate for an ecosystem on either Europa or Enceladus is based on methanogens. The usual way to tell biogenic from abiogenic methane is with isotopes - not an option on Cassini. However the ratio of ethane to methane is another way. Biogenic production of methane tends to be pretty pure methane while thermogenic production of methane make 1% or more ethane as well.
I just interviewed Carolyn Porco Aug 16th at Spacefest 2007. She has a wealth of information about her team and their explorations of Saturn and her Moons! She also gave a fantastic talk on Cassini and Saturn, and a great slide show as well! It was a pleasure meeting her and chatting with her throughout the weekend!
Those of you who are interested to know how small satellites like Calypso come to have the shapes that they do should look at the Porco et al. (2007) paper on http://ciclops.org/sci/papers.php . (Look at the top of the list under 2007). In that paper we show that the shapes of the small sats near to the rings were likely due to accretion of ring material; for the inner most ones very close to the rings, the accretion must have occurred around a dense shard. For the outer small sats, like Calypso, within the region of the bigger moons, the formation process is less evident from their shape. But its surface shows how it has accumulated material. in any case, looks like the head of a fish (pointing to the left), doesn't it?
Just picked up the Star Trek BluRay this past weekend. If you haven't already gotten a hold of one, you should definitely do so! On top of the film, there are tons of extras. Most relevant to this forum, our Captain appears on-screen with insightful commentary on the dawn of the space age and the importance of films like Star Trek in capturing our collective imagination. You can find Carolyn in the section on Gene Roddenberry's vision (note: the word on the street is that this only appears in the BluRay release, not the DVDs).
Incidentally, most of you know this already, but in case you missed it: Earlier this fall a couple of us put together a petition to get Carolyn a cameo in the Star Trek sequel that's in pre-production right now. Please sign it if you haven't already! It's at http://www.thepetitionsite.com/1/dr-carolyn-porco-deserves-a-star-trek-cameo
I have to agree with PeterDarmady, and of course as expected, I'm glad to see there're so many people thinking as me or him. People that make US that so-loved country despite someone as GWB, people thanks to which there's something as NASA.
And as him, my heroes were (and are) people as Isaac Asimov, Carl Sagan (I remembered his death made me to cry and to know of that JUST the day I borrowed from the library "A Pale Blue Dot"), and of course Carolyn Porco and many others as them.
I've seen all the Star Trek movies in the theatre (Robert Wise's excellent Star Trek: The Motion Picture was the first Trek I ever saw.) Wise imaginatively incorporated NASA's Voyager program into the plotline...and guess which Supreme Imagining Darling of us Alliance members worked on the Voyager mission?
Now we've come full circle, with a new "first" Star Trek movie, where not only the latest in space science informs the movie, but Carolyn, herself, to boot!
Loved the movie, and agree that Carolyn needs to be in the next one.
i just came back from the movie -- and i was blown away. i have lots of thoughts i still have to gather together... i hope to put them down tomorrow.
but now, suffice to say that i found myself crying happily in the end, very moved -- and i, too, stayed to see carolyn porco's name in the credits.
Add up the contributions from scientists and engineers like Galileo, Newton, Johanas Kepler, E. Howard Armstrong, Robert Goddard, and too many more to list, and you get Carolyn Porco and the Cassini imaging team "standing on the shoulders of Giants" giving us one of the best vistas our species has ever seen.
and at least one more pair of shoulders for the next generation to stand on.
Mike1137 aside, I think this fascinating (non-political) discovery is momentous. The discovery rate and data recovery on this mission has been amazingly abundant. And to think that the full extent of this mission's impact on the scientific community is as much as decade's down the road. Up to now, no planetary missions (excepting, maybe, the combined Mars missions)have gathered so much data to be mined.
I have to thank Carolyn Porco and her team for such an incredible effort in keeping the constituency (the American tax payer)awed, amazed and informed. Nice job! Keep it up as I've come to rely on your witty take on the data. Excellent P/R for NASA as well. Of course, Moon Rovers in inauguration day parades don't hurt P/R much either.
Thanks Team Porco. Your work is much appreciated!
