There is the New Horizons Pluto/Kuiper probe belt sent in 2006. The thing is fast, it passed Jupiter in 13 months and is currently beyond the orbit of Uranus.
New Horizons is traveling at about 15 km/s, 2 km/s slower than Voyager 1, and is still slowing down. When New Horizons reaches the same distance from the sun as Voyager 1 is now, its speed will be about 13 km/s (8 mi/s).[15] The close flyby of Saturn and Titan gave Voyager 1 a massive advantage with its extra gravity assist.http://en.wikipedia.org/wiki/Voyager_1
