The New Horizons spacecraft, launched in 2006, completed a dramatic flight past the icy dwarf planet of Pluto and its moons in July 2015. After 10 years and more than 3 billion miles, on a historic voyage that has already taken it over the storms and around the moons of Jupiter, New Horizons completed a flyby of a small Kuiper Belt object (KBO) called 2014 MU69 (Ultima Thule) on January 2019.
