NASA's New Horizons probe is on an ambitious mission to survey Pluto and other objects in the kuiper belt. In 2010 it passed the halfway mark, and is predicted to reach Pluto on July 14, 2015.
This spacecraft is on an Earth-and-solar-escape trajectory, meaning it will one day exit our solar system and continue its journey into interstellar space. On February 28, 2007 it passed by Jupiter, on June 8, 2008 it traversed the orbit of Saturn, and it finally passed the orbit of Uranus on March 18, 2011.
