The Multiple Instrument Distributed Aperture Sensor (MIDAS) is a diffraction-limited, wide-field imaging spectrometer that utilizes distributed apertures and optical interferometer techniques to achieve simultaneous high spatial and spectral resolution. Here we describe the results of a science and technical feasibility study of MIDAS prototypes funded under the NASA High Capability Instrument Concepts and Technology (HCICT) program as a potential science payload for missions to the outer planets and their icy satellites. The high spatial resolution capabilities of MIDAS combined with nm spectral resolution will greatly advance our understanding of icy satellite surface composition in terms of minerals, organics, volatiles, and their mixtures. From 100 km mapping orbits, cm-scale imagery from MIDAS could revolutionize our understanding of the geology, dynamics, and history of icy moon surfaces. From higher orbits, MIDAS can engage in global, high resolution imaging spectroscopy with m-scale resolution for months at a time. Beyond traditional remote sensing, MIDAS is well suited to active techniques, including remote Raman, Fluorescence, and IR illumination investigations, in order to resolve surface composition and explore otherwise dim regions.
