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

JUPITER FLYBY
Jupiter science included studies of Jovian meteorology, satellite geology and composition,Auroral phenomena, and magnetospheric physics.
C/A Date 28 Feb 2007
Range 32 RJupiter
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’sNorth pole: always visible.
Tvashtar stretches ~340km above the surface.

TVASHTAR MOVIE 5 frames 8 minutes
First direct measurements of plume dynamics. Ejection speed ~1 km/sec. Acceleration during descent. Apparently non-ballistic trajectories.
AND FINALLY, MAGNETOTAIL EXPLORATION
Flying down Jupiter’s deep magnetotail to perform the first traverse through a giant
planet’s magnetotail.

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 discoverieswill likely be the ones we
Don’t anticipate.
