The Stratospheric TeraHertz Observatory (STO) is a NASA funded, Long Duration Balloon (LDB) experiment designed to address a key problem in modern astrophysics: understanding the Life Cycle of the Interstellar Medium (ISM). STO will survey a section of the Galactic plane in the dominant interstellar cooling line [C II] (1.9 THz) and the important star formation tracer [N II] (1.46 THz) at ~1 arc minute angular resolution, sufficient to spatially resolve atomic, ionic and molecular clouds at 10 kpc. The science flight instrument package hosts four [CII] and four [NII] HEB receivers. There is also one 492 GHz Schottky receiver for observing the [CI] line. In this paper we discuss preparations for the scheduled Antarctic science flight in December 2011.
