STS-51-G was the eighteenth flight of NASA's Space Shuttle program, and the fifth flight of Space Shuttle Discovery. The seven-day mission launched from Kennedy Space Center, Florida, on June 17, 1985, and landed at Edwards Air Force Base, California, on June 24. Sultan Salman Al Saud of Saudi Arabia was on board as a payload specialist; Al Saud became the first Arab, the first Muslim, and the first member of a royal family to fly into space. It was also the first Space Shuttle mission which flew without at least one astronaut from the pre-Shuttle era among its crew.
Discovery lifted off from Pad A, Launch Complex 39, Kennedy Space Center (KSC), at 7:33 am EDT on June 17, 1985. The mission's crew members included Daniel C. Brandenstein, commander; John O. Creighton, pilot; Shannon W. Lucid, Steven R. Nagel, and John M. Fabian, mission specialists; and Patrick Baudry, of France, and Prince Sultan Salman Al Saud, of Saudi Arabia, both payload specialists.
