Cassini's deep dive through a geyser plume on Enceladus

As the long-lasting and spectacularly successful Cassini mission to Saturn winds down, its controllers are getting more daring.

Today, on a very low, very fast pass, Cassini will fly directly through a geyser plume erupting from Saturn's moon Enceladus.

The plume is thought to consist of salt water spray from a warmish ocean hidden beneath the moon's icy crust--- but that's what today's surface-skimming flyby will try to find out.
