Paper Abstract

This paper describes a low-mass, (approximately 1.2 kg) low- power (approximately 1.5 watts) ultraviolet telescope- imaging spectrograph which covers the wavelength range 65 - 165 nm with a spectral resolution of 0.5 nm. The instrument is an evolution of the EUV channel of the Ultraviolet Imaging Spectrograph for the Cassini mission in which the mechanical structure, detector electronics, and logic electronics were modified in order to significantly reduce mass and power. It has a novel combination of optical coatings which maximize its throughput for wavelengths greater than 115 nm but still provide significant sensitivity at the shorter wavelengths. The instrument design is optimized to meet the 1-A atmospheric science objectives of the Pluto Express fly-by mission, but it is also suitable for observing the outer atmospheres of other planets including earth.
