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, which had been against NASA policy prior to this mission.
STS-79 was the 17th flight of Space Shuttle Atlantis, and the 79th mission of the Space Shuttle program. The flight saw Atlantis dock with the Russian space station Mir to deliver equipment, supplies and to exchange personnel participating in long-duration stays aboard the station as part of the Shuttle–Mir program. A variety of scientific experiments were also conducted aboard Atlantis by her crew. It was the first shuttle mission to rendezvous with a fully assembled Mir, and the fourth rendezvous of a shuttle to the space station.
