New Horizons, the NASA/ESA probe to the dwarf Planet Pluto is shortly to begin the final stages of its journey leading up and encounter with the 'ninth Planet' Pluto.
Since being launched in January 2006 and following its gravity assist/encounter with Jupiter in February 2007, it has been cruising towards Pluto.
The provisional timeline is as follows:
July 14 2014 - first long range images of Pluto and Charon
February 2015 - first images of the Pluto/Charon system able to discern small details
May 2015 - image quality from New Horizon's cameras to be better than from the Hubble Space Telescope
