South Pole
In midsummer, as the sun reaches its maximum elevation of about 23.5 degrees, high temperatures at the South Pole in January average at . As the six-month "day" wears on and the sun gets lower, temperatures drop as well: they reach around sunset (late March) and sunrise (late September). In midwinter, the average temperature remains steady at around . The highest temperature ever recorded at the Amundsen–Scott South Pole Station was on Christmas Day, 2011, and the lowest was on June 23, 1982 (for comparison, the lowest temperature directly recorded anywhere on earth was at Vostok Station on July 21, 1983, though was measured indirectly by satellite in East Antarctica between Dome A and Dome F in August 2010). Mean annual temperature at the South Pole is -49.3 °C (-56.7 °F).
Ice Challenger Expedition
In 2005 a team of six people took part in the Ice Challenger Expedition. Travelling in a specially designed six wheel drive vehicle, the team completed the journey from the Antarctic coast at Patriot Hills to the geographic South Pole in 69 hours. In doing so they easily beat the previous record of 24 days. They arrived at the South Pole on 12 December 2005.
The team members on that expedition were Andrew Regan, Jason De Carteret, Andrew Moon, Richard Griffiths, Gunnar Egilsson and Andrew Miles. 
The expedition hoped to show that wheeled transport on the continent is not only possible but also more practical. It was also aimed at increasing awareness about global warming.
