This a 1:5 scale model of the support systems module of the Hubble Space Telescope. It was fabricated by the Lockheed Missile and Space Company, the contractor responsible for building the flight spacecraft. The model depicts the exterior shell of the spacecraft as well as the exterior assemblies required for its operation. Prominent features on the model include the light shield/aperture door and the two wing-like solar arrays which flank the main tubular assembly. This is one of four scale models of the HST in the NASM collection (see also Catalogue #s 19810041000, 19830232000,). The model was donated to NASM by the Lockheed Company in August 1983.
