Cold Shower
Water vapor streams into space from the south pole of Enceladus, one of the moons of Saturn, in this October 2007 image from the Cassini spacecraft. Cassini will fly just above the moon's south pole on March 12, providing the best view to date of the source of the water plumes: cracks in Enceladus' icy crust. Cassini may briefly pass through the plume of water vapor, which freezes in the cold of space. [NASA/JPL/SSI] For more information, see our March 11 program.
