Design features, in-flight performance, and data gathered with the grating spectrometer for studying atmospheric trace gases during the Spacelab I mission are described. The main instrument components were a pointing sensor, a telescope, and the spectrometer. The pointer featured four Si solar cells for solar acquisition. The orbital motion of the Orbiter permitted recording data for altitudes from 30-130 km. Vertical profiles were obtained for CO, CO2, CH4, NO, NO2, HCl, HF, and O3. Sample results are presented for CO and CO2. The weakest CO concentrations were found at high southern latitudes. CO2 mixing ratios were homogeneous up to 90 km altitude, then decreased by nearly an order of magnitude over the interval up to 130 km.
