A uThermogravimetry/biosensor system for the Penetrator Surface Elements for the EJSM Space mission

The Europa-Jupiter System Mission (EJSM) is a joint ESA/NASA mission under study, within which there will be orbital platforms targeted to both Europa (JEO) and Ganymede (JGO) [1]. We describe here a ?Thermogravimetry/biosensor system designed to measure volatile (water/organics) compounds and detect possible biosignatures from Europa and Ganymede surface or subsurface. The instrument is studied in the framework of the Penetrator Surface Elements proposed to EJSM.
