We describe an investigation of the science potential of the filled Mills cross orbiting, imaging, optical interferometer proposed by Synnott et al. and the constraints that science places on the design of the instrument. Imaging simulations were performed with this design in order to determine its capabilities in the area of spatial resolution, dynamic range, and sensitivity. In addition, specific astronomical objects of high interest were chosen as candidate program sources to determine what science was desired for these objects, what spatial resolution, etc. was needed to perform that science, and whether or not this interferometer design could do the science.
