Abstract
We have developed generic mission architecture with James Webb Space Telescope heritage that can accommodate a wide variety of future space observatories. This paper describes the optimization of this architecture for the Single Aperture Far InfraRed (SAFIR) mission. This mission calls for a 10-meter telescope in an L2 orbit that is actively cooled to 4 Kelvin, enabling background-limited observations of celestial objects in the 30 to 800 micron region of the spectrum. A key feature of our architecture is a boom that attaches the payload to the spacecraft, providing thermal and dynamic isolation and minimizing disturbances from the spacecraft bus. Precision mechanisms, hinges and latches enable folding the observatory into a 5-m diameter fairing for launch and a precision deployment once on orbit. Precision mechanisms also articulate the telescope to minimize solar torques and increase the field of regard. The details of our design and the trades considered during its development are also described
