Just 15 minutes after its closest approach to Pluto, NASA’s New Horizons spacecraft looked back toward the planet and captured this near-sunset view of its rugged, icy mountains and flat ice plains. The smooth expanse of Sputnik Planitia (right) is flanked to the west (left) by rugged mountains up to 11,000 feet (3,500 m) high.
