How fast are these plumes turning Enceladus inside out?
How much material falls back on to the surface, and how much is permanently lost to the E ring? If the Cassini extended mission lasts till the next Saturnian equinox, perhaps photos of Enceladus' shadow on other moons will tell us more too. And Enceladus passing throught the shadows of other moons might help too. Any chance of a radio occultation of Cassini's transmissions by the plumes? |
