ABSTRACT: We have developed, built and tested a microscopy station for planetary science applications, in particular for the study of Martian dust and soil. The system consists of a sample delivery system, an optical microscope and an atomic force micrscope (AFM). The combination of microscopies allows the study of features from the millimeter to nanometer scale. LED illumination allows for full colour and UV optical imaging of the samples. The AFM uses an array of silicon and molded diamond tips and can operate in both, static and dynamic mode.
