8 X 10 COLOR PHOTO, STS 61-A Challenger CREW IN SPACE Signed by STS 61-A Challenger Astronaut Bonnie Dunbar.She was chosen as an Astronaut in 1980. SPACE FLIGHT EXPERIENCE: STS 61-A Challenger (October 30-November 6, 1985), was the West German D-1 Spacelab mission. It was the first to carry eight crew members, and was also the first in which payload activities were controlled in Germany. More than 75 scientific experiments were completed in the areas of physiological sciences, materials science, biology, and navigation. During the flight, Dr. Dunbar was responsible for operating Spacelab and its subsystems and performing a variety of experiments. Her mission training included six months of experiment training in Germany, France, Switzerland, and The Netherlands. STS 61-A launched from the Kennedy Space Center, Florida, and returned to land at Edwards Air Force Base, California. Mission duration was 7 days, 44 minutes 51 seconds. STS-32 Columbia (January 9-20, 1990), launched from the Kennedy Space Center, Florida, and returned to a night landing at Edwards Air Base in California. During the flight, the crew successfully deployed the Syncom IV-F5 satellite, and retrieved the 21,400-pound Long Duration Exposure Facility (LDEF) using the RMS. They also operated a variety of middeck experiments including the Microgravity Disturbance Experiment (MDE) using the Fluids Experiment Apparatus (FEA), Protein Crystal Growth (PCG), American Flight Echocardiograph (AFE), Latitude/Longitude Locator (L3), Mesoscale Lightning Experiment (MLE), Characterization of Neurospora Circadian Rhythms (CNCR),and the IMAX Camera. Dr. Dunbar was prime operator for the RMS retrieval of LDEF, and was principal investigator for the MDE/FEA Experiment. Additionally, numerous medical test objectives, including in-flight lower body negative pressure (LBNP), in-flight aerobic exercise and muscle performance were conducted to evaluate human adaptation to extended duration missions. Mission duration was 10 days, 21 hours, 01 minute, 38 seconds. STS-50 Columbia (June 25 to July 9, 1992). Dr. Dunbar was the Payload Commander on STS-50, the United States Microgravity Lab-1 mission which was dedicated to microgravity fluid physics, materials science and life sciences. Over 30 experiments sponsored by over 100 U.S. investigators were housed in the “Spacelab” in the Shuttle’s Payload Bay. A payload crew of four operated around-the-clock for 13 days performing experiments in scientific disciplines such as protein crystal growth, electronic and infrared detector crystal growth, surface tension physics, zeolite crystal growth, and human physiology. Mission duration was 13 days, 19 hours, 30 minutes and 4 seconds. STS-71 Atlantis (June 27 to July 7, 1995), was the first Space Shuttle mission to dock with the Russian Space Station Mir, and involved an exchange of crews. The Atlantis was modified to carry a docking system compatible with the Russian Mir Space Station. Dr. Dunbar served as MS-3 on this flight which also carried a Spacelab module in the payload bay in which the crew performed medical evaluations on the returning Mir crew. These evaluations included ascertaining the effects of weightlessness on the cardio/vascular system, the bone/muscle system, the immune system, and the cardio/pulmonary system. Mission duration was 9 days, 19 hours, 23 minutes and 8 seconds, traveling 4.1 million miles in 153 orbits of the earth. STS-89 Endeavour (January 22-31, 1998), was the eighth Shuttle-Mir docking mission during which the crew transferred more than 9,000 pounds of scientific equipment, logistical hardware and water from Space Shuttle Endeavour to Mir. Dr. Dunbar was the Payload Commander, responsible for all payload activities including the conduct of 23 technology and science experiments. In the fifth and last exchange of a U.S. astronaut, STS-89 delivered Andy Thomas to Mir and returned with David Wolf. Mission duration was 8 days, 19 hours and 47 seconds.
