New press release by the imaging team:
Cassini Pinpoints Hot Sources of Jets on Enceladus October 10, 2007 (Source: Space Science Institute) CICLOPS link to the release here. One thing I was curious about tiger stripe naming - why didn't they switch "Baghdad" and "Cairo" so we have a nice A,B,C,D progression? I can only imagine it was done on purpose, but why? -------------------- |

All..
I had seen this earlier in the AGU Abtracts but declined to post until we had some fuller reporting. Unfortunately, this is all that has came forward so far..... "Sodium issue clouds Enceladus" http://news.bbc.co.uk/2/hi/science/nature/7145530.stm quoting from this press release.... "A chemical analysis of Enceladus, led by University of Colorado planetary scientist Nick Schneider, failed to detect sodium, an element scientists say should be in a body of water that has had billions of years of contact with rock. "If you have a long-lived ocean, it's going to have salt in it," said Dr Schneider, at the American Geophysical Union (AGU) meeting in San Francisco this week, "but that ocean, if it exists on Enceladus, isn't leaking out into space." "Critics of the study accept his observations, but disagree with his conclusion; and it has led to some robust exchanges here at the AGU meeting this past week. " March flyby through the plumes is gonna be really interesting.... Craig |

Craig All... the news above from my post last year has bothered me since I first read it. However in slide 15 of this CASSINI team CHARM presentation, looks like CASSINI has found the sodium.... http://saturn.jpl.nasa.gov/multimedia/prod..._Cuzzi_Seal.pdf "CDA in situ measurements show water, sodium, silicon in E ring grains, and even some metallic grains which may be on unusual orbits" Can hardly wait for the team's update on data from the August flyby... and we have two more flyby's coming up next month!!! Wonder if they are hanging onto these results until after those encounters? Very Cool!!!! Craig |
