How a Plucky Robot Found the Long-Lost Endurance Shipwreck

In late 1914, explorer Ernest Shackleton and 27 crewmen sailed into the icy waters around Antarctica. Their state-of-the-art ship Endurance stretched 144 feet, with three towering masts, its hull ultra-reinforced to resist crumpling in the floating ice. The crew's plan was to hike across the frozen continent, but the sea had other ideas. Endurance got stuck off the coast and was slowly crushed by the floating ice, forcing the men into one of the most famous feats of survival in history. They endured for over a year, scurrying across ice floes to hunt penguins and seals, before reaching an uninhabited island.
