On October 1st, 2021, the Echelon-Cross- Echelle Spectrograph instrument onboard SOFIA (EXES) became a facility science instrument, joining FORCAST, HAWC+ and FIFI-LS. EXES has demonstrated its performance on SOFIA for many years as a PI-led instrument, has completed commissioning, and has a mature data reduction pipeline.The transition from a PI-led instrument to a facility science instrument was initiated with the goal of expanding EXES community to maximize the scientific potential and impact of the instrument.
