Antarctic ship ready for 'coldest journey'
Next spring, as the winter equinox begins in Antarctica, veteran explorer Sir Ranulph Fiennes and his Commonwealth team will attempt to become the first people to successfully cross the frozen continent in its winter.
Over a six month period, they will ski 2,000 miles - mostly in complete darkness - and in temperatures which have been recorded as low as -90 degrees.
The polar research vessel, SA Agulhas, loaded with vital supplies and equipment, sets sail for South Africa today, where Sir Ranulph Fiennes, and his five fellow team members will join the crew for the last leg of the journey.
The BBC's Matthew Price has been aboard to see how preparations have been going.
