Paper Abstract

A large area telescope of diameter 30 meters may be constructed as a set of multiple parallel coelostats, with flat mirrors feeding into a single telescope forming multiple images. These images may then be recombined into a single image. The flat mirror array must be separated by over a kilometer from the combining telescope. In space this requires that the two portions should preferably maintain a fixed direction and similar spacing between them during an exposure. A low consumable method suitable for a Lagrangiun halo orbit would be to use solar radiation pressure for controlled balance relative to the gravitational field for station keeping, and for attitude control. Arrangements of controllable solar sails are discussed and shown to have sufficient thrust.
