Launched on Jan 19, 2006, New Horizons made a spectacular flyby of Pluto in July 14, 2015.
On Jan 1, 2019, it flew by the most distant object ever visited by a spacecraft, the contact binary trans-Neptunian object 2014 MU6, nicknamed Arrokoth.
Arrokoth means "sky" in the Powhatan/Algonquin language.
New Horizons also saw evidence for methanol, water ice and organic molecules on the red surface of the 36 km Kuiper Belt object.
