New Horizons science goals
FROM MISSION PRESS KIT
Posted: January 8, 2006

Based largely on what the scientific community wanted to learn about Pluto and Charon, NASA prioritized its science goals for Pluto-system exploration in three categories:

Required

  • 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

Important

  • Characterize the time variability of Pluto's surface and atmosphere
  • Image Pluto and Charon in stereo
  • Map the terminators (day/night lines) of Pluto and Charon in high resolution
  • Map the composition of selected areas of Pluto and Charon at high resolution
  • Characterize Pluto's ionosphere and solar wind interaction
  • Search for neutral species (including 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 on Pluto and Charon

Desired

  • Characterize the energetic particle environment of Pluto and Charon
  • Refine bulk parameters (radii, masses, densities) and orbits of Pluto and Charon
  • Search for magnetic fields of Pluto and Charon
  • Search for additional satellites and rings
NASA defines mission success as meeting the "required" objectives. With its full science payload -- three optical instruments, two plasma instruments, a radio science receiver/radiometer and a dust sensor - New Horizons expects to exceed these requirements, meeting or addressing all of the objectives in each category.
