STS-51-B was the 17th flight of NASA's 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.
Byron Kurt Lichtenberg, Sc. D. is an American engineer and fighter pilot who flew aboard two NASA Space Shuttle missions as a Payload Specialist. In 1983, he and Ulf Merbold became the first Payload Specialists to fly on the shuttle.
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.
Margaret Rhea Seddon is an American surgeon and retired NASA astronaut. After being selected as part of the first group of astronauts to include women in 1978, she flew on three Space Shuttle flights: as a mission specialist on STS-51-D and STS-40, and as a payload commander for STS-58, accumulating over 722 hours in space. On these flights, she built repair tools for a US Navy satellite and performed medical experiments.

Chiaki Mukai is a Japanese physician and JAXA astronaut. She was the first Japanese woman in space, the first Japanese citizen to have two spaceflights, and the first Asian woman 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.
James Anthony "Jim" Pawelczyk is an American researcher of physiology and Kinesiology who flew aboard the NASA STS-90 Space Shuttle mission as a Payload Specialist.
Donald Alan Thomas, Ph.D. 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. Following the destruction of Columbia in 2003, no more payload specialists ever flew.
