Summary	A large aperture space telescope can provide greater persistent surveillance since it can be placed at a higher altitude without sacrificing the imaging resolution. There are significant technical challenges to realize truly persistent surveillance capabilities due to the size and surface accuracy requirement of the primary mirror. The overall objective of the proposed effort is to develop and evaluate key technologies required to achieve cost-effective large aperture space mirrors for persistent surveillance and coherent image combining using small satellites to get effective large aperture and resilience. Sparse aperture is the key approach studied for this project enabling very large aperture in space using small satellites.
