And this image is exactly why New Horizons is on its way!
While Hubble's imagery is too fuzzy to help with determining surface features, the images still reveal the overall
color of Pluto. It seems to vary from white to black to orange.
The New Horizons spacecraft is now between the orbits of Saturn and Uranus, and is in fact slightly closer to Pluto than it is to Jupiter. It is expected to passes the orbit of Uranus on 18 March 2011.
The Ralph imager on New Horizons got an impromptu test on 23 June 2006 when the spacecraft passed by (but still over a thousand kilometers away) tiny asteroid 2002 JF56.
