Felicity Ann Dawn Aston MBE is a British adventurer and climate scientist.
Between 2000 and 2003 Felicity Aston was the Senior Meteorologist at Rothera Research Station located on Adelaide Island off the Antarctic Peninsula operated by the British Antarctic Survey. As was usual at the time for British Antarctic Survey staff, she spent 3 summers and 2 winters continuously at the station without leaving Antarctica. 
In 2005 she joined a race across Arctic Canada to the 1996 position of the North Magnetic Pole, known as the Polar Challenge. She was part of the first all-female team to complete this race; they came in 6th place out of 16 teams. 
In 2009 she was the team leader of the Kaspersky Commonwealth Antarctic Expedition, which was a Commonwealth of Nations expedition in which seven women from six Commonwealth member countries skied to the South Pole in 2009 to celebrate the 60th anniversary of the founding of the Commonwealth. "Call of the White: Taking the world to the South Pole" is her account of this expedition. It was published by Summersdale in 2011 and was a finalist in the Banff Mountain Book Competition in that year.
In 2012 she became the first person to ski alone across Antarctica using only personal muscle power, as well as the first woman to cross Antarctica alone. Her journey began on 25 November, 2011, at the Leverett Glacier, and continued for 59 days and a distance of 1,084 miles (1,744 kilometers). She had two supply drops.
