A weak Arctic sun provides little warmth to two expedition members pulling supply-laden sleds across the Arctic ice. Since Robert Peary made his Arctic expedition in 1909, others have made novel attempts to the Pole—by airship in 1926, by plane in 1952, and by submarine in 1959. The North Pole continues to lure explorers into the 21st century.
