In October and November 1999, NOVA journeyed into ice-choked Antarctic waters and onto the shores of rugged Elephant and South Georgia Islands as we followed in the footsteps of Sir Ernest Shackleton. This legendary explorer's 1914-1916 Endurance expedition is one of the greatest survival stories of all time. Then, in April 2000, we returned to document Shackleton's final trial -- the crossing of South Georgia -- by three of the world's most distinguished mountaineers, Reinhold Messner, Conrad Anker and Stephen Venables. Follow the expeditions as they unfolded in real-time on this Web site, and also watch for a NOVA Giant Screen Film Shackleton's Antarctic Adventure, as well as a NOVA program, "Shackleton's Voyage of Endurance," which originally aired on March 26, 2002.
