Modern Marvels - Season 12 Episode 11 Sub Zero
7.97 44 minutes Come in from the cold while we explore some of Earth's most frigid places and examine how man copes with sub-zero climates. With the advance of technology, our boundaries have expanded–from the North and South Poles, to the depths beneath the Arctic and Antarctic sea ice, to the Moon, Mars, and outward to Saturn. Enter these forbidding territories, guided by a special breed of experts as we inspect the new US South Pole Station, try on the latest Polartec fashions with anti-microbial fibers, ride on the newest snowmobiles and Sno-Cats, sail through glacial waters on ice-breaking ships, and fly on an LC-130 transport plane. And we'll see what NASA has on the planning board for deep-space exploration, including a beach-ball robot explorer, and learn from scientists studying fish in the waters off Antarctica to understand glycoproteins, which may keep frozen tissue healthy longer for transplantation.
