Mission highlights 
Launch: 24 March 1992, 8:13 am EST. Launch originally scheduled for 23 March, but was delayed one day because of higher-than-allowable concentrations of liquid hydrogen and liquid oxygen in the orbiter's aft compartment during tanking operations. During troubleshooting, the leaks could not be reproduced, leading engineers to believe that they were the result of plumbing in the main propulsion system not thermally conditioned to the supercold propellants. Launch was rescheduled for 24 March. Launch weight: 105,982 kilograms (233,650 lb).
Carried first Atmospheric Laboratory for Applications and Science (ATLAS-1) on Spacelab pallets mounted in orbiter's cargo bay. The non-deployable payload, equipped with 12 instruments from the United States, France, Germany, Belgium, Switzerland, The Netherlands and Japan, conducted studies in atmospheric chemistry, solar radiation, space plasma physics and ultraviolet astronomy. ATLAS-1 instruments were: Atmospheric Trace Molecule Spectroscopy (ATMOS); Grille Spectrometer; Millimeter Wave Atmospheric Sounder (MAS); Imaging Spectrometric Observatory (ISO); Atmospheric Lyman-Alpha Emissions (ALAE); Atmospheric Emissions Photometric Imager (AEPI); Space Experiments with Particle Accelerators (SEPAC); Active Cavity Radiometer (ACR); Measurement of Solar Constant (SOLCON); Solar Spectrum (SOLSPEC); Solar Ultraviolet Spectral Irradiance Monitor (SUSIM); and Far Ultraviolet Space Telescope (FAUST). Other payloads included Shuttle Solar Backscatter Ultraviolet (SSBUV) experiment, one Get Away Special (GAS) experiment and six mid-deck experiments.
Landing: 2 April 1992, 6:23 am EST, Runway 33, Kennedy Space Center. Rollout distance 2,812 metres (9,226 ft). Mission extended one day to continue science experiments. Landing Weight: 93,005 kilograms (205,040 lb).
