Maggie Aderin, Shipwreck Hunting, Sea Shanties, and the Inheritance Tracks of Andy Zaltzman

On Saturday Live this week we’ll be looking up, down and all over the place. Dame Maggie Aderin, space scientist, will have us looking to the skies in wonder before David Mearns, shipwreck hunter, takes us down into the ocean deep as we marvel at his life’s work - and a man never short of a sense of wonder is writer, actor, comedian, sailor and lover of alpacas...Griff Rhys Jones.

Also today, we’ll rise from the depths to the surface for some sea shantying from The Longest Johns - and we’ll be getting the Inheritance Tracks of Andy Zaltzman.

Presenter: Adrian Chiles Producer: Ben Mitchell Assistant Producers: Lowri Morgan and Alice McKee Researcher: Angharad Butler Editor: Glyn Tansley
