Mission Name: SMART 1The Smart-1 Infrared Spectrometer (SIR) is a near-infrared monolithic grating spectrometer which will perform lunar surface mineralogy studies. The instrument will be used to perform reflectance spectroscopy in 256 spectral channels in the range from 930 - 2400 nm, with a spectral resolution of 60 nm and a maximum spatial resolution of approximately 300 m. The SIR optics, sensor head, and preamplifier, consisting of a slit entrance, a collimator to focus the beam, a grating to disperse the light, and a CCD detector, are in a box mounted on the outside of the spacecraft. The electronics are housed inside the spacecraft. The SIR is co-aligned with the AMIE imager.
The resolution will allow discrimination between common lunar surface materials, such as pyroxenes, olivines and feldspars, and the instrument may be able to detect water ice, carbon dioxide, and carbon monoxide. The scientific objectives are to provide global coverage of the Moon at these wavelengths and to allow studies of the formation of craters and maria and of space weathering on the lunar surface.
