Fastest Earth departure speed

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. Pluto is the only planet in the Solar System yet to be surveyed by a spacecraft.
