The New Horizons Space Craft
New Horizons was launched at 19:00 UT (2:00 p.m. EST) on 19 Jan. 2006 on an Atlas V 551 booster with a Star 48B third stage directly into a trajectory to take it to the Pluto system and on to an encounter with a Kuiper Belt Object. In order to accomplish this, a gravity assist from Jupiter was required. For a 4-month period centered on 28 Feb 2007 a jovian observational campaign was carried out and the data were officially archived in the PDS. The flyby passed within 2.3X10**6 KM (32 jovian radii), moving at 21 km/sec. Nearest approach occurred at -8 deg. latitude, lifting New Horizons 2.5 degrees out of the plane of the solar system.

The craft is powered by a radiothermal generator (RTG) and has a 2.1 m high-gain antenna. Data from the Long Range Reconnaisance Imager (LORRI), Ralph that is composed of two parts, a visible CCD imager (MVIC) and a near-infrared imaging spectrometer (LEISA), an ultraviolet imaging spectrometer (Alice), a toroidal electrostatic analyzer and retarding potential analyzer (SWAP), a time-of-flight ion and electron sensor (PEPSSI) and the Radio Science Experiment (REX) were obtained at Jupiter.

Basic Mission Goals
Basic Goals of the NEW HORIZONS mission are to:
  • Characterize the global geology and morphology of Pluto and Charon
  • Map the surface composition of Pluto and Charon
  • Characterize the neutral atmosphere of Pluto and its escape rate

Acquisition of data at Jupiter was an add-on.
