A team of explorers is setting off on an epic expedition to walk across Antarctica during its winter.
They'll be faced with constant darkness and average temperatures of -70ºC, so it's no wonder no one has ever done it before!
Super explorer Sir Ranulph Fiennes is leading the The Coldest Journey expedition.
The expedition ship leaves London on Thursday afternoon and should reach Antarctica in just over a month.
There are loads of supplies on board, including 165 rolls of toilet paper, 4,400 packets of soup and 230kg of chocolate!
Sir Ranulph Fiennes has been called "the greatest living explorer". He was the first person to reach both the North and South Poles, and the first to cross the Antarctic and Arctic Oceans. He's also climbed Mount Everest.
