The fastest speed at which a spacecraft has ever departed from Earth is 58,338 kph (36,250 mph). It was achieved by NASA's New Horizons spacecraft, which launched from Cape Canaveral on 19 January 2006, beginning a nine-year flight to the planet Pluto and its moons. On 6 December 2014 mission controllers on Earth instructed the spacecraft to wake up from its hibernation. With New Horizons now functioning normally, it is due to perform a long-range survey of the small Kuiper Belt object VNH0004 before beginning its observations of Pluto and its moons in preparation for its flyby on 14 July 2015.
