n May 1990 NASA announced that Lucid was assigned to the crew of the STS-43 mission, which was scheduled to be flown in Discovery in April 1991. The mission was commanded by John E. Blaha, with Michael A. Baker as the pilot and Lucid, G. David Low, and James C. Adamson as the mission specialists. The objective of the mission was to deploy TDRS-E, a communications satellite that would form part of NASA's Tracking and Data Relay Satellite System.[53] Lucid conducts Development Test Objective (DTO) 1208, Space Station Cursor Control Device Evaluation II and Advanced Applications, at the payload station on the aft flight deck of the Space Shuttle Atlantis The launch date was postponed to July 23, and the orbiter was changed to Atlantis. The launch was delayed by a day to replace a faulty integrated electronics assembly that controlled the separation of the orbiter and the external tank, and then the countdown was halted with five hours to go due to a faulty main engine controller, and the launch was postponed to August 1. Unfavorable weather prompted yet another 24-hour delay. Atlantis lifted off on August 2.[54] The crew deployed TDRS-E without incident using the IUS.[54] The crew also conducted 32 physical, material and life science experiments, mostly related to the Extended Duration Orbiter and Space Station Freedom.[2] These included experiments with the Space Station Heat Pipe Advanced Radiator Element II (SHARE II), the Shuttle Solar Backscatter Ultra-Violet (SSBUV) instrument, Tank Pressure Control Equipment (TPCE), and Optical Communications Through Windows (OCTW). There was also an auroral photography experiment (APE-B), a protein crystal growth experiment, testing of the bioserve / instrumentation technology associates materials dispersion apparatus (BIMDA), investiga
