Paper Abstract

Two areas of great current interest are wide-sky surveys of the afterglows from distant high-energy events and higher-resoution wide-area surveys of Mars from orbit and of Jovian moons from fly-by. Large space-based telescopes would create significant capability improvements in either area. To be affordable such telescopes must be extremely light-weight relative to current technology. To be feasible such telescopes must be packaged within small volumes (relative to their deployed size) and deployed within relaxed positional tolerances. Sparse apertures reduce primary weight by factors of 5-20 but pose control and phasing challenges and increase susceptibility to radiometric noise. What is needed is a concept which reduces weight and packaged volume by a factor of 100 or more while relaxing the primary control and phasing requirements and incorporating spectral and directional flexibility.
