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

Just a thought here: Maybe the halo boundary is actually at Enceladus' Roche limit distance (liquid satellite version), which is pretty small (smaller than the putative Hill sphere radius, presumably.)
EDIT: This seems to make sense. The stuff in the halo is actually in orbit around Enceladus; beyond the critical radius it goes into orbit around Saturn. The N-S elongation is caused by excess velocity imparted to some of this stuff from the south polar plumes, which is pushing some of the material into polar elliptical orbit; presumably a lot of this gets picked off by Saturn as well & joins the E-ring. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
