Plumbing Europa's Ocean

In a new study, researchers argue they have shown there is interaction between the ocean of water inside Jupiter's moon Europa and the moon's ice shell.  So, a future probe will be able to study the composition of the ocean water by analyzing surface samples.  The study also finds Europan ocean water is salty, much like Earth's.

Of course, to search for life in that ocean will likely still require submersibles to sail the depths-- unless part of the interaction involves throwing dead whatzits onto the surface.
