How to Explore Oceans on Saturn's Moons

On Friday, the Cassini spacecraft ended its 20 year voyage with a dramatic kamikaze descent into Saturn.

But that's not quite the end of the story. 

Cassini produced many surprises – not least of which is the discovery that one of Saturn's moons, Enceladus, has a salty, liquid ocean and other building blocks of life, such as carbon and hydrogen. That has some wondering if there might be life in that ocean and oceanographers have already begun working with NASA on how to get back to there and answer that question.

Chris German is one of those scientists. He's a senior scientist in marine geology and geochemistry at Woods Hole Oceanographic Institution and co-author of an upcoming NASA roadmap for the exploration of ocean worlds. We talked with him on Living Lab Radio.
