Paper Abstract

The near-infrared spectrometer, SIR, is a flexible, compact and low mass (2 kg) instrument designed to measure reflectance spectra in the wavelength range between 935 and 2390 nm with a resolution of 6 nm per pixel. In its current implementation it is part of ESA’s technology mission SMART-1, which will be launched in 2003 and tested in an orbit around the Moon. The SIR spectrometer uses a reflection grating and an InGaAs detector. Its design is optimized to operate under extreme temperature and to withstand extreme vibrational conditions. For the SMART-1 mission its capabilities are of particular importance for the study of features like maria, craters, and fracture ridges that will provide deeper insights into crust and mantel material and therefore, into the development of the Moon and the Earth-Moon system.
