SOFIA at Full Operation Capability: Technical Performance

The Stratospheric Observatory for Infrared Astronomy (SOFIA), the largest airborne observatory in the world, is in full operation capability since February 2014 and is currently completing its Observing Cycle 6 Program. The first four years of operation have provided the opportunity to assess the high-level observatory’s technical performance and to identify additional observatory upgrades. Since the start of routine operations, performance and productivity in several areas of the observatory, including science, operations and engineering, have been tracked by metrics and statistics. In this paper we present the general observatory technical performance as the observatory has reached its maturity and has served the science community with over 2900 h of scientific observations.
