Alice is any one of two ultraviolet imaging spectrometers; one used on the New Horizons spacecraft and the other used on the Rosetta spacecraft. [1] Alice is a small telescope with a spectrograph and a special detector with 32 pixels each with 1024 spectral channels detecting ultraviolet light. [2]

2025年2月11日 · 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.

2007年9月26日 · The New Horizons ALICE instrument is a lightweight (4.4 kg), low-power (4.4 Watt) imaging spectrograph aboard the New Horizons mission to Pluto/Charon and the Kuiper Belt. Its primary job is to determine the relative abundances of various species in …

2006年3月8日 · Technicians at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, install the Alice ultraviolet imaging spectrometer on NASA’s New Horizons spacecraft. Alice is one of seven science instruments designed for the Pluto flyby mission, which is planned for launch in January 2006.

ALICE is an Ultraviolet Imaging Spectrometer that will characterise the composition of the nucleus and coma and the nucleus/coma coupling of comet 67 P. The instrument is looking at spectral features at wavelengths in the ultra-violet (UV) range from 70 to 205 nm.

The New Horizons Alice instrument is a lightweight (4.4 kg), low-power (4.4 Watt) imaging spectrograph aboard the New Horizons mission to Pluto/Charon and the Kuiper Belt. Its primary job is to determine the relative abundances of various species in Pluto's atmosphere.

Alice is a compact, general-purpose UV imaging telescope/spectrometer, which is now flying aboard NASA's New Horizons mission to Pluto and the Kuiper Belt and the ESA/NASA Rosetta asteroid flyby/comet rendezvous mission. The two Alices are called ``P-Alice'' (as part of the Persi suite on New Horizons) and ``R-Alice''.
