September 18,1991, 12:38:42 a.m. PDT, Runway 22, Edwards AFB, Calif. Rollout distance: 9,513 feet. Rollout time: 50 seconds. Landed scheduled for KSC, but diverted to Edwards due to bad weather. Orbiter returned to KSC Sept. 26,1991. Landing Weight: 192,780 lbs.

Mission Highlights:
Primary payload, the Upper Atmosphere Research Satellite (UARS), deployed on the third day of the mission. During its planned 18-month mission, the l4,500-pound observatory will make the most extensive study ever conducted of the Earth's troposphere, the upper level of the planet's envelope of life- sustaining gases which also include the protective ozone layer. UARS has ten sensing and measuring devices: Cryogenic Limb Array Etalon Spectrometer (CLAES); Improved Stratospheric and Mesospheric Sounder (ISAMS); Microwave Limb Sounder (MLS); Halogen Occultation Experiment (HALOE); High Resolution Doppler Imager (HRDI); Wind Imaging Interferometer (WlNDII); Solar Ultraviolet Spectral Irradiance Monitor (SUSIM); Solar/Stellar Irra- diance Comparison Experiment (SOLSTICE); Particle Environ- ment Monitor (PEM) and Active Cavity Radiometer Irradiance Monitor (ACRIM II).
Secondary payloads were: Ascent Particle Monitor (APM); Middeck 0-Gravity Dynamics Experiment (MODE); Shuttle Activation Monitor (SAM); Cosmic Ray Effects and Activation Monitor (CREAM); Physiological and Anatomical Rodent Experiment (PARE); Protein Crystal Growth II-2 (PCG II-2); Investigations into Polymer Membrane Processing (IPMP); and the Air Force Maui Optical Site (AMOS) experiment.
