Ralph: A Visible/Infrared Imager for the New Horizons Pluto/Kuiper Belt Mission
Full text linkThe New Horizons instrument named Ralph is a visible/near infrared
multi-spectral imager and a short wavelength infrared spectral imager. It is
one of the core instruments on New Horizons, NASA's first mission to the
Pluto/Charon system and the Kuiper Belt. Ralph combines panchromatic and color
imaging capabilities with IR imaging spectroscopy. Its primary purpose is to
map the surface geology and composition of these objects, but it will also be
used for atmospheric studies and to map the surface temperature. It 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. These
characteristics and its high degree of redundancy make Ralph ideally suited to
this long-duration flyby reconnaissance mission.Comment: 18 pages, 15 figures, 4 tables; To appear in a special volume of
