Abstract: Hundreds of apertures, a few meters wide and arrayed across a hundred kilometers in space, can provide snapshot images of exo-planets, where "green patches" will be searchable. "Densified-pupil imaging " is the new ingredient announcing such performance. Simulations show the Earth as it would appear from 3 parsecs, with cloud formations visible. Densified-pupil imaging has been incorporated in the Optical Very Large Array ground-based precusor, for which a prototype telescope element is under completion. Design options for 150 m (Exo-Earth Discoverer) and 150 km (Exo-Earth Imager) space arrays are presented.
