Getting Wet
Featured on October 27, 2015
The Cassini spacecraft will take a quick shower on October 28, when it flies through the plumes of water and ice shooting into space from the south pole of Saturn's moon Enceladus, shown in this earlier Cassini image. The plumes appear to originate from a global ocean below the moon's icy crust. Cassini's instruments will sample the plume material to give scientists a better understanding of the moon's structure and composition. [NASA/JPL/SSI]
