Almost 170 years after its mysterious disappearance, the HMS Terror has been discovered at the bottom of the Arctic Ocean. The Terror was one of two ships that vanished in 1848 while searching for the Northwest Passage, a route connecting the northern Atlantic and Pacific oceans. In the late 15th century, European ship captains began braving treacherous Arctic icebergs in hopes of finding a shortcut around North America so they could ship goods more quickly. The Terror, along with a companion ship, the Erebus, and their English captain, Sir John Franklin, got caught in ice, and he and more than 120 crewmen eventually perished. Franklin is still a hero in England, despite never finding the Northwest Passage. For now, the Terror and Erebus (which was discovered in 2014) remain at the bottom of the Arctic. But the long elusive goal of traversing a Northwest Passage is now possible in warmer months because climate change is melting much of the Arctic ice cover. That melting concerns Canadian meteorologist Roger Provost. As he told SpaceDaily.com, “In a few years, it will completely disappear.”
