MISSION_DESCRIPTION
MISSION_OBJECTIVES_SUMMARY 
    Mission Objectives  ==================     The scientific objectives of the EPOCh investigation of the EPOXI    mission were to:       o Observe transits by known extrasolar planets (hot Jupiters) to        search for perturbations due to terrestrial planets in low-order        resonances,       o Search those same systems for secondary occultations of the hot        Jupiter by the star, and       o Characterize the Earth as an analog for extrasolar planets by        observing its rotational light curve and integrating over the        disk at wavelengths sensitive to vegetation (red edge), Rayleigh        scattering, and clouds.     The general scientific objective of the DIXI investigation of the EPOXI    mission was to study a second comet with the same set of instrumentation    that were used at comet Tempel 1 to help determine which cometary features    are primordial and which are the result of subsequent evolutionary    processes.  Specific goals included:       o Searching for outbursts and if found producing spectral maps of        these events and correlating the outbursts with surface features,       o Obtaining infrared spectral maps of gasses in the innermost coma        and investigating the distribution of dust and gas in the coma,       o Searching for frozen volatiles on the surface of the comet,       o Performing broad band imaging to determine the size of the nucleus        and producing a shape model,       o Mapping the brightness and color variations of the surface and        locating topographical features that disclose the processes by        which the comet was formed, and       o Mapping the temperature of the surface to assess the thermal        conductivity of the interior and the migration of subsurface        volatiles.
