Mission Highlights:
Primary payload, Tracking and Data Relay Satellite-4 (TDRS-4) attached to an Inertial Upper Stage (IUS), became third TDRS deployed. After deployment, IUS propelled satellite to geosynchronous orbit. Secondary payloads: Orbiter Experiments Autonomous Supporting Instrumentation System-1 (OASIS-1); Space Station Heat Pipe Advanced Radiator Experiment (SHARE); Protein Crystal Growth (PCG); Chromosomes and Plant Cell Division (CHROMEX); two Shuttle Student Involvement Program (SSIP) experiments; and Air Force experiment using orbiter as calibration target for ground-based experiment for Air Force Maui Optical Site (AMOS) in Hawaii. Crew also photographed Earth with hand held IMAX camera.
