Abstract
Since several years, EADS-Astrium has developed, in partnership with BOOSTEC, Silicon Carbide (Sic) structural pieces for space telescope applications. This technology has appeared adequate not only for optical elements (mirrors) but also for the complete Telescope structures, thanks to high stiffness, low coefficient of thermal expansion and high thermal conductivity of Sic. At the time being, two space Sic telescopes are operational in observation and scientific missions. Two other monolithic Sic telescopes, among the largest ever built, are in manufacturing progress. The latest innovations in Sic technology have been implemented in the ALADIN Telescope for the AEOLUS mission (LIDAR dedicated to wind speed measurement).
