The first helicopter load of passengers of the Australasian Antarctic Expedition gather prior to being rescued, with the Akademik Shokalskiy ship, which got stuck in ice in Antarctica on background, on Jan. 2, 2014. All 52 passengers aboard a research ship icebound in the Antarctic for more than a week have been rescued by a Chinese helicopter and taken to an Australian polar icebreaker, maritime authorities said Thursday. The 22 crew members of the Russian-flagged MV Akademik Shokalskiy remain on board the ship, which has been stranded since Dec. 24, south of Hobart, Tasmania. A helicopter rescue was the last option left for the passengers after French, Chinese and then Australian icebreakers failed to smash through more than 20 kilometers of pack ice to free the Shokalskiy.

Scientists Ziggy Marzinellia and Graeme Clark, from the University of NSW, Australia, prepare a suitable surface for a helicopter landing next to the Akademik Shokalskiy ship, which got stuck in ice in Antarctica, on Dec. 31, 2013. Passengers aboard the polar research vessel trapped in Antarctic ice for a week learned they would be taken off in batches when the weather improves enough to allow a helicopter rescue. The 74 people aboard the Russian-flagged MV Akademik Shokalskiy have been stranded since Dec. 24. French, Chinese and Australian icebreakers have tried and failed to smash through to them, leaving an air rescue as the last resort.
