Enceladus Flyby

FYI: Tomorrow, October 28, 2015, the Cassini spacecraft will do a close flyby of Saturn's moon Enceladus. At closest approach Cassini will be just 30 miles above the surface and fly through the icy plume spraying from the region of the south pole which is thought to come from a vast global ocean underneath the surface ice.

The spray is speculated to be the result of hydrothermal activity and Cassini will sample the chemistry measuring for molecular hydrogen among other things.

After this, there will be one final Enceladus flyby in December.

Here's a NASA animation of tomorrow's flyby:
