In episode 14 Professor John Zarnecki spoke about the science conducted from the surface of Titan by the Huygens lander in January 2005.

The European Space Agency’s Huygens probe had hitched a lift to Saturn aboard the Cassini orbiter. Six years after its arrival at Saturn, Cassini is still making spectacular discoveries about Saturn, its majestic rings and its many moons.

In this episode, Professor Carl Murray from Queen Mary University of London talks about some of those discoveries and how the mission will eventually come to an end.

This interview was recorded during the National Astronomy Meeting in Manchester in March 2012.
