Just over five years ago, on 30 June 2004, the Cassini orbiter and the Huygens probe it was delivering to Titan went into orbit around Saturn and began detailed exploration of the Saturnian system. Over this time more and more of the surface of Saturn's moon Titan has been covered by the suite of complementary instruments, and as we learn more Titan becomes increasingly intriguing.
