New Horizons: A Journey to New Frontiers
New Horizons is New Frontiers 1Launch: Jan ‘06
Pluto-CharonJuly 2015
KBOs2016-2020
Jupiter SystemMarch 2007
First Time Exploration First Time Exploration of The Solar System’s “Third Zone”of The Solar System’s “Third Zone”
PKB AO-Defined Measurement Objectives
Group 1 Objectives: Characterize the global geology and morphology of Pluto and Charon Map surface composition of Pluto and Charon Characterize the neutral atmosphere of Pluto and its escape rate
Group 2 Objectives: Characterize the time variability of Pluto's surface and atmosphere Image Pluto and Charon in stereo Map the terminators of Pluto and Charon with high resolution Map the composition of selected areas of Pluto & Charon at high resolution Characterize Pluto's ionosphere and solar wind interaction Search for neutral species including H, H2, HCN, and CxHy, and other
hydrocarbons and nitriles in Pluto's upper atmosphere Search for an atmosphere around Charon Determine bolometric Bond albedos for Pluto and Charon Map the surface temperatures of Pluto and Charon
Group 3 Objectives: Characterize the energetic particle environment of Pluto and Charon Refine bulk parameters (radii, masses, densities) and orbits of Pluto & Charon Search for magnetic fields of Pluto and Charon Search for additional satellites and rings

New HorizonsScience Traceability
New Horizons meets or exceeds all of the PKB mission Group 1 (AO-required) measurement objectives, plus all
of the (AO-desired) Group 2, and 3 of the 4 Group 3 measurement objectives.
Science Objectives Are Accomplished with Great Functional Redundancy
Toward New Frontiers
New Horizons is Demonstrating That Exciting Low Cost Outer Planet Missions Are Indeed Feasible.
