CICLOPS article on Enceladus' plume: http://ciclops.org
Composition of plumes compared to comets: http://photojournal.jpl.nasa.gov/catalog/PIA10357 And the INMS spectrum showing simple and "complex" organics (their definition of "complex" is very different than mine - we're not talking teterodotoxin here): http://photojournal.jpl.nasa.gov/catalog/PIA10356 (Dalton = amu; benzene is about m.w. 78) From CICLOPS cpcomments: "Also, it is now unambiguous that the jets emerging from the south polar fractures contain organic materials heavier than simple methane -- acetylene, hydrogen cyanide, formaldehyde, propane, etc." -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

From CICLOPS cpcomments: "Also, it is now unambiguous that the jets emerging from the south polar fractures contain organic materials heavier than simple methane -- acetylene, hydrogen cyanide, formaldehyde, propane, etc." -Mike As sparkling water goes, I am not sure I'd like the taste of this.... Ciclops' unsurprising gushing (!) notwithstanding, there are a few people (e.g. Veronique Vuitton at the Titan Chemistry workshop here in Miami http://www.chem.hawaii.edu/Bil301/Titan2007.html ) noting that some attention should be paid to possible chemistry on the surfaces of the INMS instrument itself (e.g. during Titan flybys, benzene or Phenyl (C6H5), cant remember which, peaks AFTER closest approach). In other words could these 'Enceladus' organics be reaction products of Enceladus water with Titan gunk on the inside of the instrument? I personally doubt it, but wanted to note that 'unambiguous' is a pretty heavy duty word for what may be a rather complex situation. I guess I won't complain too much if a Titan Flagship does a little bit of Enceladus science on the way, though. Looks not entirely uninteresting.... |
