![]() While some of the hornets in the bottom container of the experiment remained active through flight day 7, no new nests were created until after the mission's completion, and the average lifespan of the hornets that flew into space was considerably less than that of the control group. : 28 However, a failure in the water system resulted in an unexpected rise of the humidity level in the experiment, which resulted in the deaths of 202 out of the 230 hornets and 103 pupae out of the 120 in the experiment. Originating from Tel-Aviv University, it was intended to observe the effects of microgravity on oriental hornets and their ability to build combs in zero-g. ISAIAH was the first microgravity experiment flown for the Israel Space Agency (ISA). : 4 External experiments using the Ultraviolet Plume Imager (UVPI) on the LACE satellite and observations at theĪir Force Maui Optical Station (AMOS) were also conducted while Endeavour was in orbit. On the middeck, a variety of experiments were conducted, including the Israel Space Agency Investigation About Hornets (ISAIAH), the Solid Surface Combustion Experiment (SSCE), and the Shuttle Amateur Radio Experiment (SAREX II). Secondary Experiments STS-47 Endeavour crewmembers inside Spacelab Test subjects included the crew, Japanese koi fish (carp), cultured animal and plant cells, chicken embryos, fruit flies, fungi, plant seeds, frogs and frog eggs, and oriental hornets. Life sciences included experiments on human health, cell separation and biology, developmental biology, animal and human physiology and behavior, space radiation, and biological rhythms. Materials science investigations covered such fields as biotechnology, electronic materials, fluid dynamics and transport phenomena, glass and ceramics, metals and alloys, and acceleration measurements. ![]() The Payload Crew Training Manager was Homer Hickam, who also worked during the mission as a Crew Interface Coordinator to talk to the crew during their science experiments and relay any concerns from the scientists on the ground. Spacelab-J included 24 experiments in materials science and 20 life sciences experiments, the majority of which were sponsored by NASDA and NASA, while 2 were sponsored by collaborative civilian efforts. As the mission commander, Gibson was free to work with both teams. Brown, Lee, and Mohri, were assigned to the red team, and would conduct experiments while Apt, Davis, and Jemison, assigned to the blue team, would rest, and vice versa. Like many previous missions, the international crew was divided into red and blue teams which would work in two 12-hour shifts for around-the-clock operations. The mission's primary payload was Spacelab-J - a joint mission between NASA and the National Space Development Agency of Japan (NASDA) - which used a crewed Spacelab module to conduct microgravity research in materials and life sciences. EDT on September 12, 1992, and was the first on-time mission without launch delays since STS-61-B in 1985. Mission highlights Unimak Island as seen from Endeavour.Īt the beginning of September, a problem with an oxygen line in the shuttle's main propulsion system was identified, however, it was resolved without forcing a postponement of the mission. When asked at a NASA press conference if intimate activities would be taking place on the mission, Davis denied that possibility. ![]() However, when Lee and Davis's marriage became known to NASA officials in January 1991, the officials decided to keep the assignment as is, given that both crewmembers already had important roles within the upcoming mission. Seats 5–7 are on the Middeck.Īs female and male astronauts became more prominently integrated with the shuttle program, NASA enacted an unwritten rule that husband/wife couples would not be assigned to the same mission. Lee and Jan Davis, contrary to NASA policy.Ĭrew seating arrangements Seat This mission carried Mamoru Mohri, the first Japanese astronaut aboard the shuttle, Mae Jemison, the first African-American woman to go to space, and the only married couple to fly together on the shuttle, Mark C. The mission mainly involved conducting experiments in life and material sciences inside Spacelab-J, a collaborative laboratory inside the shuttle's payload bay sponsored by NASA and the National Space Development Agency of Japan (NASDA). STS-47 was NASA's 50th Space Shuttle mission of the program, as well as the second mission of the Space Shuttle Endeavour. ![]()
