Over one hundred years ago, in July 1910, Captain Robert Falcon Scott set out from England on the ill-fated Terra Nova expedition.
Scott's goal was to be the first to reach the South Pole, at the white heart of Antarctica. For much of his journey, he was accompanied by early film-maker, Herbert Ponting.
Ponting's unique film of that expedition, The Great White Silence, has been digitally restored by the British Film Institute, and received its world television premiere on Discovery Channel, to coincide with the anniversary of the departure of the Terra Nova from Cardiff.
James Cracknell, who endured his own Antarctic expedition last year, will compare his modern day experience of the trek to the Pole - the equipment, diet, mental challenges and physical preparations - with Scott's ultimately tragic journey, bringing a new perspective to this already legendary tale.
