In this paper we summarize a concept definition and feasibility analysis for formation flying a representative large space telescope composed of separated optical elements. A virtual-structure construct (an equivalent rigid body) is created by unique metrology and control that combines both centralized and decentralized methods. The formation may be in orbit at GEO for super-resolution Earth observation or it may be in an Earth-trailing orbit for astrophysics. Extended applications are envisioned for exo-solar planet interferometric imaging by a formation of very large separated optics telescopes. Space telescopes, with such large apertures and optics with focal length f/10 to f/100, are not feasible if connected by massive metering structures. Instead, the new virtual-structure paradigm of information and control connectivity between the formation elements provides the necessary spatial rigidity and alignment precision for the telescope.
