PROPOSAL: KBO FLYBY 2019

Page 30: OPAG: We Did It!

KBO EXTENDED MISSION PROPOSAL IN CONTEX

PT1 2014

PT3, 2014 PT3, 2015

PT1, 2015

Ø The Planetary Decadal Survey that enabled New Horizons called for a Kuiper Belt-Pluto Mission to explore both the Pluto System and small KBOs.

Ø New Horizons and its payload were explicitly designed to carry out this KBO mission in response to the NASA PKB AO.

Ø In 2014 the New Horizons project identified 2 potential KBOs targets using HST; they are called Potential Targets (PTs) 1 and 3.

Ø New Horizons is healthy and has more fuel and ΔV capability aboard (~130 m/sec) than originally after Pluto.

Ø A KBO extended mission is viable.

KBO Extended Mission Science Objectives

PT1 2014

PT3, 2014 PT3, 2015

PT1, 2015

Ø Conduct a close flyby of a primordial KBO planetesimal.

Ø Conduct distant science flyby observations of 10-20 other KBOs.

Ø Conduct heliospheric cruise science in the Kuiper Belt; specifically heliospheric plasma, dust, and neutral H/He observations.

Ø Potentially conduct astrophysical cruise science.
