More than five years after braking into Saturnian orbit, the Cassini probe at Saturn just keeps outdoing itself. On November 2nd and again on the 21st, Cassini flew closely by Saturn's small but active moon Enceladus, which is spouting geysers of water vapor and ice dust (with interesting chemical contaminants) from its south polar region. The geysers line up in rows along the great "tiger stripe" cracks, which in other views are prominent in the relatively young, uncratered south polar terrain.
Emily Lackdawalla blogs about the new images — which are still in mostly raw form, straight out of the spacecraft's camera — for The Planetary Society here here. I'll let her do the talking in superlatives.
More of the images, as stunning stereo pairs. Free-fuse them by crossing your eyes.
Did I mention that Cassini just did a flyby of Rhea too?
