It is 100 years to the day since Captain Robert Falcon Scott and his team reached the South Pole.
Scott and his men reached the pole five weeks after Norwegian Roald Amundsen and then perished on their return journey.
Scott's grandson, Falcon Scott, is in Antarctica helping to conserve the Terra Nova Hut, which was the base for the ill-fated expedition.
Mr Scott says he was moved to tears when he arrived at the hut at Cape Evans four weeks ago.
He says preserving his grandfather's legacy is important - even though the team never made it home.
