What to know
New Horizons flew past Pluto on July 14, 2015, returning the first close images of its surface, including the vast heart-shaped ice plain Sputnik Planitia. It then continued into the Kuiper Belt, passing the small body Arrokoth in 2019, and remains outbound today.
Did you know?
It left Earth faster than any spacecraft before it, crossing the Moon's orbit in about nine hours, a journey that took the Apollo crews about three days.
Little known
New Horizons carries some of the ashes of Clyde Tombaugh, the astronomer who discovered Pluto in 1930. He flew past his own discovery 85 years later.
