New Horizons is a flyby mission by NASA / APL targeting Kuiper Belt. Launched January 19, 2006. Currently 60 AU from the Sun.
ABOUT NEW HORIZONS
New Horizons performed the first flyby of Pluto in July 2015, revealing a surprisingly complex and geologically active world. It then continued to the Kuiper Belt, flying past Arrokoth (2014 MU69) on January 1, 2019 — the most distant object ever visited by a spacecraft. It continues heliospheric observations as it heads toward the outer solar system.
KEY DISCOVERIES
- Plutos heart-shaped nitrogen ice plain (Sputnik Planitia)
- Mountains of water ice on Pluto up to 3,500m high
- Plutos thin but complex atmosphere
- Arrokoth (2014 MU69) contact binary shape
TECHNOLOGY & FIRSTS
- Fastest launch speed of any spacecraft (58,000 km/h)
- First mission to Pluto
- First Kuiper Belt object flyby (Arrokoth)
