About New Horizons Reaches Pluto
On July 14, 2015, NASA's New Horizons spacecraft swept within about 7,800 miles of Pluto's surface, the first time any mission had ever reached the distant dwarf planet. The images it radioed back revealed soaring water-ice mountains, plains of nitrogen ice, and a vast heart-shaped region that captured the world's imagination overnight. That frozen world, once just a dot of light since its discovery in 1930, suddenly had a face.
