Dan Snow steps aboard the RRS Discovery in Dundee, the first purpose built scientific research vessel for the Antarctic. Guided around the ship by Ali Gellatly, he learns what life and adventure was like aboard this unique vessel.

The legendary polar explorer Captain Scott commanded Discovery's first expedition south from 1901-1904, during which the ship would spend two years locked in the polar ice.

Also on that expedition was none other than Ernest Shackleton, who would later go on to gain global renown after the Endurance expedition of 1914.
