【題目】Powered by courage and determination，F(xiàn)elicity Aston,33，became the first person to ski alone across Antarctica on 15，Jan,2012.

Aston finished the 59day trip almost exactly a century after Roald Amundsen first reached the South Pole in 1911.Aston crossed 1,084 miles from the Ross Ice Shelf to Hercules Inlet.

Aston，a freelance travel writer，and explorer，faced temperatures that averaged－25 degrees as she pulled two sleds across the ice and thick snow on her nearly twomonth trip. The scariest moment came when her two lighters failed to work while she was in the Transantarctic Mountains. The lighters started working again at lower altitudes.

While early Antarctic explorers were cut off from the outside world，Aston's access to a satellite phone meant that friends and family could follow her online as she regularly tweeted(在Twitter上發(fā)微博)and made almost daily podcasts(播客)about her journey. An interactive map showed Aston's progress in real time. And while she skied，Aston listened to bands.

On New Year's Eve she noted that there would be no champagne.“No wine with me to toast the new year but treating myself to spoonfuls of the peanut butter，” Aston tweeted as the new year approached.

In Aston's last podcast，the emotional traveler recorded after she reached Hercules Inlet, “I seem to have got here in a rush or something and I don't really feel prepared for it，”said Aston.“It feels amazing to be finished and greatly sad that it's over at the same time.”

Weather permitting，Aston will return home today where she says she is looking forward to some “red wine and a hot shower”．
