Explanation: Artist's concept of the New Horizons spacecraft encountering Pluto and its largest moon, Charon (foreground) in July 2015. The craft's miniature cameras, radio science experiment, ultraviolet and infrared spectrometers and space plasma experiments will characterize the global geology and geomorphology of Pluto and Charon, map their surface compositions and temperatures, and examine Pluto's atmosphere in detail.
