New Horizons spacecraft flies by Pluto a year ago
One year ago today, the New Horizons spacecraft made its closest approach to Pluto and its moon Charon. Since then, NASA scientists have made numerous discoveries about the now-dwarf planet, such as craters, mountains and seas of solid nitrogen.
Last month, scientists discovered super-grand canyon on Charon that makes Arizona's Grand Canyon look like a scratch!
