One interesting question that needs to be answered is just how long Enceladus' plume has lasted over geological time. Just out of curiosity, has anybody calculated how much "thrust" is generated by this continuous outgassing?
Reason I ask is that there just might be enough cumulative effect to cause axial instability, and therefore possibly explain some of the moon's odd geology. Perhaps the hot spot is migratory? -------------------- 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.

If most of the plume follows ballistic trajectory and recontacts the surface, there is that much less thrust.
If the south polar area is consistently the outgassing site, the cummulative effect is to be pushing on the Encelodosian orbit at a right angle. As Enceladus goes 360 degrees around Saturn, any effect on the orbital inclination will be canceled out, assuming constant average thrust around the orbit. If materials are escaping the Saturn system primarily in the same 'southerly' direction, then the plumes are working against the mass of the entire Saturnian system. I suspect the total effect over the life of the solar system to be infinitesimal. |
