Princess Anne is taking a trip to a place where no royal has yet set foot – the icy continent of Antarctica. Anne will join survey ship HoS Endurance, which is 11 weeks into its nine-month mission to collect data to investigate global warming. The 56-year-old Princess Royal will probably be flown by one of the ship’s two Lynx helicopters to one of Britain’s Antarctica bases, where temperatures drop as low as minus 30°. Endurance – motto “By endurance we conquer” – is named after Sir Ernest Shackleton’s ship, which got trapped in ice on his 1914-15 expedition. [9 January 2007]
