STS-47 was NASA's 50th Space Shuttle mission of the program, as well as the second mission of the Space Shuttle Endeavour. 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). 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. Lee and Jan Davis, contrary to NASA policy.

As 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. 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.[2] When asked at a NASA press conference if intimate activities would be taking place on the mission, Davis denied that possibility.[3]
At 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.[4]
STS-47 launched from Pad 39B at 10:23:00 a.m. EDT on September 12, 1992, and was the first on-time mission without launch delays since STS-61-B in 1985.[5]
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. 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. 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. As the mission commander, Gibson was free to work with both teams.[6] Because of the 24-hour schedule, the crew wasn't sent any traditional wake-up calls by mission control.[7]
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.[8] 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.[9]
Aboard the Spacelab Japan module, Jemison tested NASA's Fluid Therapy System, a set of procedures and equipment to produce water for injection, developed by Sterimatics Corporation. She then used IV bags and a mixing method, developed by Baxter Healthcare, to use the water from the previous step to produce saline solution in space.[13] Jemison was also a co-investigator of two bone cell research experiments.[14] Another experiment she participated in was to induce female frogs to ovulate, fertilize the eggs, and then see how tadpoles developed in zero gravity.[15]
Secondary Experiments
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).[16]:4 External experiments using the Ultraviolet Plume Imager (UVPI) on the LACE satellite and observations at the Air Force Maui Optical Station (AMOS) were also conducted while Endeavour was in orbit.[8]
ISAIAH was the first microgravity experiment flown for the Israel Space Agency (ISA). 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.[16]: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. 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. None of the hornet pupae that flew into space metamorphized.[17][18]
Also on board were two experiments prepared by Ashford School of Art & Design in Kent, United Kingdom, which, at the time, was a girls-only school.[16] The school had won a competition run by Independent Television News. The experiments were contained in G-520. The first one injected a few grams of cobalt nitrate crystals to a sodium silicate to create a chemical garden in weightless condition. The growths, which were photographed 66 times as they developed, spread out in random directions, twisted, and, in some cases, formed spirals. A second experiment to investigate how Liesegang rings formed in space failed to operate correctly due to friction in parts of the mechanism. On its return, the experiment was exhibited in the London Science Museum.[20]
While in orbit, Jemison planned to speak from orbit on a live TV conference to Chicago grade-school students at an event hosted by NASA and the Chicago Museum of Science and Industry. The event was planned for September 16, 1992, at 7:00 p.m. central time.[21]
The mission, scheduled to end on September 19, 1992, was extended for one more day to complete certain experiments.[22]

Spacelab was a reusable laboratory developed by European Space Agency (ESA) and used on certain spaceflights flown by the Space Shuttle. The laboratory comprised multiple components, including a pressurized module, an unpressurized carrier, and other related hardware housed in the Shuttle's cargo bay. The components were arranged in various configurations to meet the needs of each spaceflight.
Ulf Dietrich Merbold is a German physicist and astronaut who flew to space three times, becoming the first West German citizen in space and the first non-American to fly on a NASA spacecraft. Merbold flew on two Space Shuttle missions and on a Russian mission to the space station Mir, spending a total of 49 days in space.
Guion Stewart Bluford Jr. is an American aerospace engineer, retired United States Air Force (USAF) officer and fighter pilot, and former NASA astronaut, in which capacity he became the first African American to go to space. While assigned to NASA, he remained a USAF officer rising to the rank of colonel. He participated in four Space Shuttle flights between 1983 and 1992. In 1983, as a member of the crew of the Orbiter Challenger on the mission STS-8, he became the first African American in space as well as the second black person in space, after Cuban cosmonaut Arnaldo Tamayo Méndez.
Mamoru "Mark" Mohri, AM is a Japanese scientist, a former NASDA astronaut, and a veteran of two NASA Space Shuttle missions. He is the first Japanese astronaut who was part of an official Japanese space program. The first Japanese person in space, Toyohiro Akiyama, was a journalist who was trained in the Soviet Union.
STS-51-B was the 17th flight of the NASA Space Shuttle program and the seventh flight of Space Shuttle Challenger. The launch of Challenger on April 29, 1985, was delayed by 2 minutes and 18 seconds, due to a launch processing failure. Challenger was initially rolled out to the pad to launch on the STS-51-E mission. The shuttle was rolled back when a timing issue emerged with the TDRS-B satellite. When STS-51-E was canceled, Challenger was remanifested with the STS-51-B payloads. The shuttle landed successfully on May 6, 1985, after a week-long mission.
STS-61-A was the 22nd mission of NASA's Space Shuttle program. It was a scientific Spacelab mission, funded and directed by West Germany – hence the non-NASA designation of D-1. STS-61-A was the ninth and last successful flight of Space Shuttle Challenger before the disaster. STS-61-A holds the current record for the largest crew—eight people—aboard any single spacecraft for the entire period from launch to landing.
STS-42 was a NASA Space Shuttle Discovery mission with the Spacelab module. Liftoff was originally scheduled for 8:45 EST on January 22, 1992, but the launch was delayed due to weather constraints. Discovery successfully lifted off an hour later at 9:52:33 EST. The main goal of the mission was to study the effects of microgravity on a variety of organisms. The shuttle landed at 8:07:17 PST on January 30, 1992, on Runway 22, Edwards Air Force Base, California. STS-42 was the first of two flights in 1992 of Discovery, the second of which occurred during STS-53, which launched on December 2, 1992. The mission was also the last mission of the Space Shuttle Discovery to have a seven-member crew until STS-82, which was launched on February 11, 1997.
STS-55, or Deutschland 2 (D-2), was the 55th overall flight of the NASA Space Shuttle and the 14th flight of Shuttle Columbia. This flight was a multinational Spacelab flight involving 88 experiments from eleven different nations. The experiments ranged from biology sciences to simple Earth observations.
STS-83 was a NASA Space Shuttle mission flown by Columbia. It was a science research mission that achieved orbit successfully, but the planned duration was a failure due to a technical problem with a fuel cell that resulted in the abort of the 15 day duration. Columbia returned to Earth just shy of four days. The mission was re-flown as STS-94 with the same crew later that year.
STS-94 was a mission of the United States Space Shuttle Columbia, launched on 1 July 1997.
STS-90 was a 1998 Space Shuttle mission flown by the Space Shuttle Columbia. The 16-day mission marked the last flight of the European Space Agency's Spacelab laboratory module, which had first flown on Columbia on STS-9, and was also the last daytime landing for Columbia.
Bonnie Jeanne Dunbar is an American engineer and retired NASA astronaut. She flew on five Space Shuttle missions between 1985 and 1998, including two dockings with the Mir space station.
Dirk Dries David Damiaan, Viscount Frimout is an astrophysicist for the European Space Agency. He flew aboard NASA Space Shuttle mission STS-45 as a payload specialist, making him the first Belgian in space.

Both were Space Shuttle missions; her first was STS-65 aboard Space Shuttle Columbia in July 1994, which was a Spacelab mission. Her second spaceflight was STS-95 aboard Space Shuttle Discovery in 1998. In total she has spent 23 days in space.
Donald Alan Thomas is an American engineer and a former NASA astronaut.
A payload specialist (PS) was an individual selected and trained by commercial or research organizations for flights of a specific payload on a NASA Space Shuttle mission. People assigned as payload specialists included individuals selected by the research community, a company or consortium flying a commercial payload aboard the spacecraft, and non-NASA astronauts designated by international partners.
NASA Astronaut Group 12 was a group of 15 astronauts announced by NASA on June 5, 1987.
NASA Astronaut Group 10 was a group of 17 astronauts that were announced on May 23, 1984 and consisted of seven pilots and ten mission specialists. Although selected in 1984, no member of the group would fly until 1988 due to the Challenger disaster and the resulting grounding of the Space Shuttle fleet.
NASA Astronaut Group 11 was a group of 13 NASA astronauts announced on 4 June 1985.
