PDS3













Instrument Description
The New Horizons instrument named Ralph is a visible/near infrared multi-spectral imager and a short wavelength infrared spectral imager. MVIC and LEISA are incorporated in RALPH, which combines panchromatic and color imaging capabilities with SWIR imaging spectroscopy. RALPH is a compact, low-mass (10.5 kg) power efficient (7.1 W peak), and robust instrument with good sensitivity and excellent imaging characteristics. Other than a door opened once in flight, it has no moving parts making it ideally suited for long-duration flyby reconnaissance mission.

Measurement Objectives
  • Pluto objectives are to map the surface geology and composition of Pluto and moons and for atmospheric studies and to map the surface temperature.
  • At Jupiter a series of observations were carried out within the constraints of calibration and shake-down activities for the Pluto mission.

The RALPH/MVIC & LEISA data are housed at the PDS/SBN node
