August 2,1991, 11:01:59 a.m. EDT. Launch originally set for July 23, but was moved to July 24 to allow time to replace a faulty integrated electronics assembly that controls orbiter/external tank separation. Mission postponed again about five hours before liftoff on July 24 due to a faulty main engine controller on number three main engine. Controller replaced and retested; launch reset for Aug. 1. Liftoff set for 11:01 a.m. delayed due to cabin pressure vent valve reading and postponed at 12:28 p.m. due to unacceptable return-to-launch site weather conditions. Launch reset for Aug. 2. Launch Weight: 259,374 lbs.
Inclination: 28.45 degrees
Duration: 8 days, 21 hours, 21 minutes, 25 seconds.
Distance: 3,700,400 miles

August 11, 1991, 8:23:25 a.m. EDT, Runway 15, Kennedy Space Center, Fla. Rollout distance: 9,890 feet. Rollout time: 60 seconds. First landing scheduled at KSC since 61-C in January 1986 (which was diverted to Edwards). Landing Weight: 196,088 lbs.
Primary payload, Tracking and Data Relay Satellite-5 (TDRS-5) attached to an inertial Upper Stage (I US), deployed about six hours into flight, and IUS propelled satellite into geosynchronous orbit; TDRS-5 becomes fourth member of orbiting TDRS cluster. Secondary payloads were Space Station Heat Pipe Advanced Radiator Element II (SHARE II); Shuttle Solar Backscatter Ultra-Violet (SSBUV) instrument; Tank Pressure Control Equipment (TPCE) and Optical Communications Through Windows (OCTW). Other experiments included Auroral Photography Experiment (APE-B) Protein Crystal Growth Ill (PCG Ill); Bioserve / Instrumentation Technology Associates Materials Dispersion Apparatus (BIMDA); Investigations Into Polymer Membrane Processing (IPMP); Space Acceleration Measurement System (SAMS); Solid Surface Combustion Experiment (SSCE); Ultraviolet Plume imager (UVPI); and the Air Force Maui Optical Site (AMOS) experiment.
