Abstract

This paper describes Ma_Miss (Mars Multispectral Imager for Subsurface Studies), the miniaturized instrument for spectrometric and stratigraphic analysis of sub-soil developed by SELEX Galileo in the context of ESA ExoMars mission. The Ma_Miss experiment is coordinated by the Principal Investigator Angioletta Coradini (IFSI-INAF, Rome) and is funded by the Italian Space Agency (ASI). The exploration of Mars requires a detailed in-situ investigation of the Martian surface and sub-surface. Determining the composition of the Martian subsoil will provide a direct indication of the steps through which the sample material evolved along geological timescales. Ma_Miss is an instrument fully integrated in the Drill system (developed by SELEX Galileo) hosted by a Rover operating on Mars surface; Ma_Miss illuminates the wall of the drill borehole and acquires its reflectance signal in the Visible and Infrared (0.4-2.2 micron) range, analyzes it through a miniaturized spectrometer (20nm spectral resolution), and transmits the digital data to the Rover. The innovative instrument concept was driven by several key needs, related to challenging scientific requirements and extreme environmental constraints. Implementation of the concept has required a deep interdisciplinary concurrent development in order to solve critical aspects of engineering and manufacturing, covering miniaturized monolithic optics and novel concept for fiberoptic connectors capable to automatically mate/de-mate during the robotic assembly of the Drill elements on Mars.
