摘要：

A Mossbauer spectrometer for the mineralogical analysis of the Mars surface is under development. This instrument will be installed on a Mars-Rover, which is part of the Russian Mars'96 mission. Due to power and mass restrictions, the electromechanical drive and the electronic components have been extremely miniaturized, and for the rude conditions during take-off and landing, very much ruggedized in comparison to standard systems. Solid-state detectors (PIN-diodes) are used for gamma- and X-ray detection in backward geometry and will also give information on the elemental composition by Xray fluorescence spectroscopy. The different operations of the spectrometer are controlled autonomously by a microprocessor.
