Below a darkened Enceladus, a plume of water ice is backlit in this view of one of Saturn's most dramatic moons. The image was taken on Feb. 20, 2012.
The Fields, Particles and Waves instruments were prime (particularly the ion and neutral mass spectrometer [INMS]) to study the composition, density, three-dimensional structure and variability of plumes; with E-14, and E-17, this flyby provided good coverage of south polar regions.
