Instrument Description
The New Horizons ALICE instrument is a lightweight (4.4 kg), low-power (4.4 Watt) imaging spectrograph. It incorporates an off-axis telescope feeding a Rowland-circle spectrograph with a 520-1870 Å spectral passband, a spectral point spread function of 3-6 Å FWHM, and an instantaneous spatial field-of-view that is 6 degrees long. Different input apertures that feed the telescope allow for both airglow and solar occultation observations during the mission. The focal plane detector is an imaging microchannel plate (MCP) double delay-line detector with dual solar-blind opaque photocathodes (KBr and CsI) and a focal surface that matches the instrument's 15-cm diameter Rowland-circle.

Measurement Objectives
  • Pluto objectives are to search for or observe atmospheres around Pluto and Charon and to make surface reflectivity measurements of Pluto and his moons.
  • At Jupiter a series of observations were carried out within the constraints of calibration and shake-down activities for the Pluto mission.

The ALICE data are housed at the PDS/SBN node
