Edmund Hillary, Edmund Shackleton, Marco Polo, and Neil Armstrong all accomplished feats that forever change humanity - breaking boundaries, redefining our limitations, and going where no one ever dared. But who was the greatest? We looked back at the feats of history's most prolific explorers on land, air, and ice, and picked our winners.
By Sea (Round 2)
Magellan: Although he underestimated how large the earth was, resulting in a long journey that cost him his life in the Philippines, one of his ships still circumnavigated the globe – meaning even death couldn't stop him. Cousteau's ship, meanwhile, was accidentally sunk by a barge.
Cook: Zheng He's legacy was short-lived; the Chinese emperor ordered his charts destroyed. Cook, on the other hand, managed to accurately map travel destinations as diverse as Newfoundland, Alaska, and Australia's Great Barrier Reef (where, it should be noted, he ran aground).
