Current imaging satellites are limited in resolution and field of regard by the aperture size of their primary optical mirror. To get a large optical mirror into space, current launch weight andsize restrictions must be overcome. Membrane-like optical mirrors can overcome these restrictionswith their very lightweight and flexible properties.
