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? -------------------- |

Joe Spitale and Carolyn Porco have a paper in Nature, out tomorrow but online today, on the sources of Enceladus' South Polar jets entitled, "Association of the jets of Enceladus with the warmest regions on its south-polar fractures." As you can tell from the title, many of the jet sources are located near hotspots seen by CIRS, and nearly all are located along one of the tiger stripes in the south polar region. For those without access to the article, there is a press release located at http://saturn.jpl.nasa.gov/news/press-rele....cfm?newsID=780 . In addition, a map showing the hotspot and jet source locations can be found at http://photojournal.jpl.nasa.gov/catalog/PIA08385 . These are really intriguing results, and it would be interesting to see how these sources match up with those of the jets seen a couple of weeks ago. Are the sources variable? Are different parts of the stripes active at different times (as Terry Hurford suggests) or are they more constant and tied to thermal emission sites (as Spitale and Porco suggest)?
