1 NEW HORIZONS NASA’s Pluto-Kuiper Belt Mission: “The First Mission To the Ninth Planet And the Solar System’s Third Zone”  XXXX Days Since Launch  XXXX Days Still To Pluto

2 Pluto was discovered in January- February 1930, by Clyde Tombaugh at Lowell Observatory, Arizona. Pluto: A Little Background  Pluto is a Small, Distant World  <1% Mars’s Max Apparent Diameter (0.1 arcsec)  And 50,000 times fainter than Mars (V~14)

3 An Historic Journey Pluto-Charon July 2015 KBOs Jupiter System March 2007 The Initial Reconnaissance of The Solar System’s “Third Zone” Launch Jan 2006

4 A MISSION OF FIRSTS

5 Pluto-Charon: What We Know The Best Hubble Images of Pluto Are Still Crude

6 But Now We Know The System is a Quadruple

7 PLUTO-KUIPER BELT EXPLORATION A Reconnaissance Expedition To Pluto-Charon & the Kuiper Belt The Highest Priority Medium-Scale Mission New Start Of The Planetary Decadal Survey

8 SO WE PROPOSED IT, WON IT,AND BUILT IT

9 SCIENTIFIC PAYLOAD Instruments:  REX radio science & radiometry  RALPH VIS/IR imaging & spectroscopy  ALICE UV imaging spectroscopy  LORRI High-resolution imager  SWAP plasma spectrometer  PEPSSI energetic particle spectrometer  SDC EPO Student Dust Counter

10 OUR ATLAS V 551 LAUNCH VEHICLE Centaur Interstage Adapter (12.5 ft Dia) CCB Cylindrical Interstage Adapter RD-180 Engine Common Core Booster TM (CCB) Single RL10 Engine Centaur Upper Stage 5-meter Short Payload Fairing (68 ft) Solid Rocket Boosters Aft Transition Skirt/Heat Shield 5-Meter Payload Fairing Boattail Centaur Aft Stub Adapter Centaur Forward Load Reactor Payload Adapter (PLA) Centaur Conical Interstage Adapter

11 FINISHING TOUCHES

12 ALL DRESSED UP AND READY TO FLY

13 LAUNCH: 19 JAN 2006 GOING SUPERSONIC!

14

15 ROUTE OF FLIGHT

16 JUPITER FLYBY Jupiter science included studies of Jovian meteorology, satellite geology and composition, Auroral phenomena, and magnetospheric physics. C/A Date28 Feb 2007 Range32 R Jupiter

17 FLYBY OBJECTIVES

18 SUCCESS: NEW RESULTS

19 AND WE OBSERVED IO ERUPTIONS GALORE  At least 11 volcanic Plumes were detected.  We obtained the most detailed view ever of a plume on Io.  Tvashtar is near Io’s North pole: always visible.  Tvashtar stretches ~340 km above the surface. Tvashtar Prometheus Masubi Io night side illuminated by Jupiter

20 TVASHTAR MOVIE  5 frames  8 minutes

21 TVASHTAR MOVIE  5 frames  8 minutes

22 TVASHTAR MOVIE  5 frames  8 minutes

23 TVASHTAR MOVIE  5 frames  8 minutes

24 TVASHTAR MOVIE  5 frames  8 minutes

25 TVASHTAR MOVIE  5 frames  8 minutes  First direct measurements of plume dynamics.  Ejection speed ~1 km/sec.  Acceleration during descent.  Apparently non-ballistic trajectories.

26 AND FINALLY, MAGNETOTAIL EXPLORATION Flying down Jupiter’s deep magnetotail to perform the first traverse through a giant planet’s magnetotail. ~300 R J Equatorial Plane Noon-Midnight Plane R J Former Terra Incognita

27

28 UNEXPLAINED PLASMA QUASI-PERIODICITIES A 10 hour period at 450 R J !

29 Farwell Jupiter

30 CRUISE 2 OVERVIEW PS-Hibernation PS-Normal PS-TCM AS-Normal AS-TCM AS-EA AS-SA 3A-Normal 3A-Encounter 3A-TCM

31 NEXT UP: IN 2015: WHAT WE CAME FOR  Jan-Mar: Observatory Phase  April: Begin Approach Phase  14 July: Closest Approach  Aug-Dec: Data Downlink

32 REVOLUTIONARY DATASETS  Six months of encounter science.  Exceed Hubble resolution for months.  Map Pluto and all three satellites.  Make composition maps of Pluto and Charon.  Map surface temperature fields.  Directly measure Pluto’s escape rate.  Assay Pluto’s atmospheric structure and composition.  Determine if either Pluto or Charon differentiated.  Locate additional satellites. The most exciting discoveries will likely be the ones we Don’t anticipate.

33 ANTICIPATE DRAMATIC RESULTS Triton & Pluto At Best HST Resolution Triton from Voyager

34 AND THEN ON TO KBOs LATE IN THE NEXT DECADE

35 ONLY AMERICA CAN DO THIS

36 BACKUP SLIDES

37 INSTRUMENT PAYLOAD
