Here we the present the experiment MA-MISS. MA-MISS is located in the DIBS (Drill Integrated package for Borehole Science) drill that will be flown on the EXOMARS Mission. This experiment is considered as a prototype for different probes that can be located inside drills in order to study planetary subsurfaces. The challenges in building this experiment will be described. The main scientific objective of this experiment is the study of the Martian subsurface. The study of surface and subsurface mineralogy of Martian soil and rocks is the key for understanding the chemical-physical processes that led to the formation and evolution of the red planet. The water and other volatiles history, as well as weathering processes are the signatures of present and past environmental conditions, associated to the possibility for life. Surface samples are highly influenced by exogenic processes (weathering, erosion, sedimentation, impact) that alter their original properties. So, the analyses of uncontaminated samples by means of instrumented drills and in situ analytic stations are the key for unambiguous interpretation of the original environment that lead rock formation. Analysis of subsurface layers is the only approach that warranty measurements on samples close to their original composition. Scientific goals are strictly related to the depth of the borehole; straight water detection ask for deep penetrations function of latitude and local geology, bedrock analysis requires samples from depths, probably ranging in several meters, in function of site geology, and analysis of soil need few meters in depth. A drilling system, coupled with an in situ analysis package, is needed to perform in situ investigations. MA- MISS is a spectrometer devoted to observe the lateral wall of the borehole generated by the Drill System. The instrument is fully integrated with the Drill and shares its structure and electronics.
