Near-Infrared Mapping Spectrometer Of The Phobos Space Mission To The Planet Mars

The ISM instrument of the PHOBOS space mission is a near-infrared imaging spectrometer for mineralogic studies of planet Mars and Phobos surface, with a 128 spectral elements (splited in two bands 0.8 to 1.6 μm and 1.6 to 3 μm). The description of this instrument is focused on the optical and detection system, based on two focal plane assembly of PbS linear arrays. Finally we will describe the first results of the calibration.
