NASA Space Mission to Pluto and Ultima Thule

Pluto Safari is your interactive guide to the first mission to Pluto, the last unexplored planet - and to the January 1, 2019 flyby of Kuiper Belt Object 2014 MU69 - nicknamed Ultima Thule. It's a free app from the developers of SkySafari, the next-generation award-winning astronomy app.

Follow the New Horizons spacecraft on its historic mission to explore the mysterious icy worlds at the edge of our solar system. New Horizons flew by Pluto and Charon on July 14, 2015. It is now venturing out even further and will visit 2014 MU69 - nicknamed Ultima Thule by the New Horizons Science team - in the Kuiper Belt region beyond Neptune on January 1, 2019 - New Years day!
