Hi David, the idea that New Horizons will outstrip the Voyagers is a very common misconception due to this sentence in the post-launch press release: "The 1,054-pound, piano-sized spacecraft is the fastest ever launched..." New Horizons did leave Earth after launching faster than any other spacecraft to date, having launched about four percent faster than the previous record holder, Ulysses. And New Horizons will receive one further burst of speed during its flyby of Jupiter in 2007. However, both Voyagers also received gravity assists from Jupiter, and because they both flew closer to Jupiter than New Horizons will, their gravity assists were larger. In addition, both Voyagers also received boosts from Saturn flybys, and Voyager 2 went on to further flybys of Uranus and Neptune. The Uranus flyby sped it up, but the Neptune one actually slowed it down. New Horizons, on the other hand, gets only one more close flyby, of Pluto. And Pluto's mass is so tiny that it will be unlikely to add enough speed to New Horizons to allow it ever to overtake either of the Voyagers.
(If this sounds pat, it's because I wrote it for a Planetary Radio Q and A. Hope it's right. ) --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
