The General Assembly of the European Geoscience Union is in Vienna in April. There is a strong planetary and space science section. A session program with links to abstracts can be found at http://www.cosis.net/members/meetings/programme/view.php?p_id=127 .<br /><br />I'll probably be there so let me know if there are any sessions you want me to go to. I'll certainly be at the Mars and the Titan imaging sessions, if I can.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em> Arthur Clarke</p> </div>

Sorry, my wife got in there first <img src="/images/icons/smile.gif" /> . But it will be a great conference, I am officially going to present the team's work on salinity management.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em> Arthur Clarke</p> </div>

A couple things that struck me in a quick, partial scan of the subjects:<br /><br />First in-situ Observations of Lightning and related Phenomena in the Atmosphere of Titan<br /><i>"The observed events below140km have been compared with the electric field of lightning and resonance phenomena observed on earth..."</i><br /><br />There were a couple other presentations using data from the same instrument to detect possible lightning on Titan. I have not seen any definative claim for lightning on Titan. I wonder how close they will or can get to one.<br /><br /><br />The Mars flyby of Rosetta: an opportunity for atmospheric sounding<br /><i>"It will be able to search for other minor species (CH4, H2CO...) and to study possible local variations..."</i><br /><br />Really!?! I wonder how Rosetta's detection capabilities of methane and formaldehyde on Mars will compare with those undertaken so far. When is this flyby anyway?<br /><br />Of course, all the Huygens presentations should be interesting, especially the imaging and entry trajectory. I'm particularly interested in the gas chromatograph/mass spectrometer results. Organic chemistry is greek to me but I'm curious to see the list of individual organic compounds that they are able to identify. the more complex ones are probably the hardest to identify, but are the most intriguing. <br /><br /> <div class="Discussion_UserSignature"> </div>
TheRosetta flyby of Mars has been kept at a low profile. I was not aware of it until now. But according to the Rosetta home page it will happen in February 2007. It will be a very close flyby too - 200 km.<br /><br />I imagine that Rosetta will be well equipped to look for methane, ammonia and a range of organic gasses as these are quite abundant in cometary out gassing events.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em> Arthur Clarke</p> </div>
The Huygen's abstracts are typically very sketchy because the deadline for submission was January 21. However abstracts can be updatred on line by the authors, so some might be added to. However, I expect the meat of the material to be in the presentations.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em> Arthur Clarke</p> </div>
I wonder if Rosetta could be put into a Martian orbit after its comet rendezvous. <br />It’s got a lot of power to be spent on just roaming the asteroid belt. But I guess that’s a long way off from now.<br /><br />Good luck with salinity management.<br />
CRC LEME leme.anu.edu.au (see program 4)<br /><br />If you go to any one of the EGU sessions there is an author search function. Type in "Clarke" then look for either J or JDA Clarke, and you'll see what I mostly get up to with my day job <img src="/images/icons/smile.gif" /> Just remember I am presenting on behalf of the team, so my name is on a lot more stuff than I actually work on.<br /><br />Cheers<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em> Arthur Clarke</p> </div>
Jon,<br /><br />A fun little project you might like to pursue, especially if you're going to be attending the Huygens presentations:<br /><br />Check on the pronunciation(s) of "Huygens" used by the various participants. Awhile back, stevehw33 started a THREAD on the correct (dutch) pronunciation. The rest of the thread has highs and lows in typical SDC fashion, but my questions are: Given that the only pronunciation I've heard from scientists of varying nationalities in the web-cast briefings is "hoygens", is this the general European pronunciation of the dutch scientist's name or is it particular to the Huygens probe scientists? Do they use a different pronunciation when speaking their native languages? If there are any Dutch scientists present at the conference, how do they feel about the use of the "hoygens" pronunciation by the project scientists?<br /><br />Stevehw33 does a good job of describing the dutch pronunciation in his opening post and provides this LINK. You can also hear it in the audio news story HERE. <div class="Discussion_UserSignature"> </div>
Thanks for the link to the audio file. For those of you with knowledge of German it sounds like the sound in German for "oe" or the o umlaut sound, ö, as in for example G<b>ö</b>del.<br /><br /><br /> Bob Clark <div class="Discussion_UserSignature"> </div>
It also sounds like the "H" sound at the beginning of Huygens is similar to the guttural "ch" sound in German, as in for example <i>ach</i>:<br /><br />German Consonants : "Ch", "Chs" and "Ck" <br />http://www.ex.ac.uk/german/abinitio/pronounce/pronoch.html<br /><br /><br /> Bob Clark <div class="Discussion_UserSignature"> </div>
I am Dutch, but when I speak in English about Huygens I use the 'Hoygens' pronounciation. Otherwise noone will understand me and I will have to repeat it a couple of times, which is quite annoying <img src="/images/icons/laugh.gif" />
I wonder if the Dutch in Europe have the same problem. <br />The question really nags me: Do I hear the Huygens project scientists using the "Hoygens" pronunciation because they are translating into english, or is that the universally accepted pronunciation on the Huygens project. Is "hoygens" possibly even a Europe-wide pronunciation. Does it matter if its the probe or the scientist being referred to? What about the Germans? Do the German scientists go with the "hoygens" pronunciation? Do they use the Dutch "Howchuns" amongst themselves or has the "hoygens" stuck, at least when referring to the probe. Am I way to obsessed with this? <div class="Discussion_UserSignature"> </div>
Hoygens would be pretty close to the pronunciation if it were a German name. I think that could be where it comes from.
well, in that same thread i posted a link to how it SHOULD be pronounced, please respect our great Dutch scientist <img src="/images/icons/smile.gif" /><br /><br />http://www.conedm.nl/huygens.mp3<br /><br />
One thing I've noticed is that the greater a person, the more names they have. It should be a mark of honor and greatness that one's name be translated into many languages across the world. <br /><br />(Maybe it should worry you that we've only come across two major versions of Huygen's name so far.<img src="/images/icons/smile.gif" />) <div class="Discussion_UserSignature"> </div>
Thanks for the suggestions. Vienna is not a place I have ever thought about going to, so this local knowledge is much appreciated.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em> Arthur Clarke</p> </div>
