Technicians work on the payload for the New Horizons mission to the planet Pluto on Nov. 4, 2005 at the Kennedy Space Center in Cape Canaveral, Fla. A successful journey to Pluto would complete an exploration of what were considered at the time to be the nine planets that was started by NASA in the early 1960s. Astronomers re-classified Pluto as a "dwarf planet" in 2006.
