A Single Aperture, Far InfraRed Observatory, called SAFIR, is a proposed NASA mission to observe the universe at wavelengths from ~30 to 800 microns. To achieve the mission objectives, the telescope must be of order 10-m in diameter and cooled to ~4K to obtain background limited performance. Northrop Grumman Space Technology (NGST) has developed a conceptual design based on our James Webb Space Telescope (JWST) and Terrestrial Planet Finder (TPF) mission architectures that utilizes a deployable telescope and a large sunshade to achieve the desired mirror temperature. Our design concept includes a 12-m diameter on-axis Gregorian telescope, which provides the wide fields of view desired by the SAFIR science team. We describe the optical design, a packaging concept that allows this telescope to fit in a standard 5- launch vehicle fairing, and initial concepts for the telescope thermal control system.
