[57.19] GEODE : In situ planetary compact geochemistry facility

The purpose of this compact and miniaturised facility is to analyse the composition and physical properties of soils and rocks of the planetary surfaces. This type of assemblage would be suitable for the Mercury and Mars Scout missions (though under different environmental conditions) which require a very lightweight scientific package. In fact, ought to the very small dimensions of this facility, it can be easily allocated either inside a microrover or on a robotic arm of a lander. The scientific experiments we propose to be onboard the facility are: XMAP (x-ray diffractometer and fluorescence), MPE (magnetic properties experiment), VIRCUI (visible and infrared close-up imager). XMAP will perform mineralogical and chemical analysis directly on the sample surface. It will allow to define the textural and petro-mineralogical characteristics of the rocks and thus information of the past environment conditions. MPE will provide answers on the magnetic phase of particles and minerals which are responsible for the magnetisation of the soil. It can perform repeated measurements in different sites or generate variable field intensity and collect particles with different sizes. VIRCUI is a multifunction microscope that can perform visible and infrared analysis of the soil and at the same time it is a support for the MPE experiment; moreover VIRCUI can also be useful for the navigation of a microrover.
