The Single Aperture Far Infrared (SAFIR) observatory - a concept design for a 10m-class spaceborne far- infrared and
submillimeter telescope, has been proposed for development, and given high priority by agency strategic planners.
SAFIR will target star formation in the early universe, the chemistry of our interstellar medium, and the chemical
processes that lead to planet formation. SAFIR is a telescope that, with passive cooling at Earth-Sun L2, achieves
temperatures that allow background-limited broad-band operation in the far infrared. This observatory is baselined as
being autonomous in deployment and operation, but consideration has been given to understanding the enabling
opportunities presented by Exploration architecture. As this architecture has become better defined, these opportunities
have become easier to understand.We present conceptual strategies that would use modestly enhanced Exploration
architecture to service and maintain SAFIR, allowing extended duration, lower risk and hardware cost, and performance
enhancements linked to the steep development curve for sensor technology. These efforts, which would rely on both
human and robotic agents, presume routine operations at Earth-Sun L2, and servicing at an Earth-Moon L1 jobsite. The
latter is understood to be easily accessible to a lunar-capable Exploration program. This study bridges the interface
between Exploration technology and astronomical space observatory technology. Such an Exploration-enhanced version
of SAFIR can be seen as a strawman for more ambitious far future work, in which much larger science instruments that
cannot be packaged in a single launch vehicle are not only serviced and maintained in space, but also constructed there.
