New Horizons launched on 19 January 2006 — one of the fastest spacecraft ever to depart Earth — operated for NASA by the Johns Hopkins Applied Physics Laboratory. A February 2007 gravity-assist flyby of Jupiter sped it onward to the first exploration of Pluto.
On 14 July 2015 it flew past Pluto and its moons, and its LORRI camera revealed an astonishingly varied world — including the bright, heart-shaped region whose western lobe lies in Tombaugh Regio, named for Pluto's discoverer Clyde Tombaugh, a small portion of whose ashes travels aboard the spacecraft. On 1 January 2019 it flew past the Kuiper Belt object Arrokoth, the most distant world ever explored up close, and it continues outward, still operating.
