Paper Abstract

The Space Infrared Interferometric Telescope (SPIRIT), a candidate NASA Origins Probe mission, is a cryogenic 6-36m variable-baseline imaging interferometer operating at 25 - 400 μm. SPIRIT utilizes dual, meter-class, telescopes which translate along opposed deployable booms. The collimated beams from the telescopes are combined in a central instrument module operating at 4K and lower. Mission-enabling mechanisms include the large, optical delay line scan mechanism, the afocal collector telescope trolley drives, and the boom deployment mechanisms. This paper provides an overview of the mechanical aspects of the conceptual design created to meet the challenging instrument requirements.
