Paper Abstract

Continuing plans for an orbiting submillimeter and infrared observatory are discussed. The Large Deployable Reflector (LDR) is seen as a dedicated observatory with a 10-year life-time, which will be useful for a wide range of astronomical observations in a largely unexplored portion of the electromagnetic spectrum. The present concept is for a 10- to 30-m-diameter clear aperture telescope operating at wavelengths from 1000 μm to a diffraction-limited 30 μm. The primary reflector will be composed of a number of close packed hexagonal segments of glass or lightweight composite material. The individual reflector segments will be attached to a truss integrating structure through position actuators providing three degrees of freedom for each segment. Other technical issues discussed are optical design, surface measurement systems, deployment and detectors.
