Historic New Horizons Flyby of Pluto
NASA's New Horizons spacecraft, launched in 2006, made astronomy history today as it flew by Pluto, camera at the ready—and scientists around the world watching and waiting for early pictures of the dwarf planet and its moons.

After nine years in space and having traveled more than three billion miles, New Horizons is the first spacecraft from Earth to reach Pluto. Its historic flyby today gives it mere hours in range of Pluto to gather all kinds of new data for scientists. The photos New Horizons is taking will provide the closest look at Pluto to date, photos that are 1,000 times higher resolution than those taken with the Hubble Space Telescope.
