A British Antarctic expedition is re-enacting Sir Ernest Shackleton's famous, although failed attempt to reach the South Pole.
However this time there is a difference. The party want to succeed where Sir Shackleton failed.
The party are all descended from explorers of the original expedition and will travel 1400 kilometres across the ice from Cape Royds to the South Pole pulling their own sledges.
The group are trying to complete the journey in the most authentic way, refusing all help from New Zealand and American bases.
Sir Shackleton became a hero for his efforts on a later Antarctic expedition where he saved his entire crew from death by sailing 1200 kilometres in an open boat, after his ship Endurance became trapped in ice.
This time the expedition will take about 70 days - as long as they survive the crevasses.
The team will finish with other descendants who will join them for the last 155 kilometres.
