The Multiple Instrument Distributed Aperture Sensor (MIDAS) is a revolutionary approach to planetary remote sensing. The integration of optical interferometric techniques and distributed aperture technology enables MIDAS to perform as a diffraction-limited, wide-field imaging spectrometer with 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 moons. Activities include testbed demonstrations in the lab during which the spatial and spectral capabilities of MIDAS-derived approaches have been explored, using both source imagery and materials relevant to outer planet environments. The high spatial resolution capabilities of MIDAS combined with nm spectral resolution will greatly advance our understanding of surface composition in terms of minerals, organics, volatiles, and their mixtures. Utilizing cm scale spatial resolution in the visible from a 100 km orbit, features such as crack movements and other indicators of tidal forcing could be resolved on the surface of Europa. At higher altitudes MIDAS engages in global, high resolution imaging spectroscopy with meter-scale resolution. Beyond traditional remote sensing, MIDAS is well suited to active techniques including remote Raman, Flourescence, and IR illumination investigations in order to resolve surface composition and explore otherwise dim regions. Other applications for MIDAS include remote sensing measurements on the Moon and Mars, where orders of magnitude advances beyond the resolutions of current data sets are possible.
