STS-51-G was the 18th 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, 1985. Sultan bin Salman Al Saud from 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. [2] 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 Launch Complex 39A, Kennedy Space Center (KSC), at 7:33 a.m. 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, from France, and Prince Sultan Sultan bin Salman Al Saud, from Saudi Arabia, both payload specialists.
STS-51-G carried three communications satellites as its primary cargo. These were Arabsat-1B (Arab Satellite Communications Organization); Morelos-1 (Mexico); and Telstar-303 (AT&T Corporation); all three were Hughes-built satellites. All three successfully utilized Payload Assist Module (PAM-D) booster stages to achieve geostationary transfer orbits (GTO) after being deployed from Discovery.
Also carried was the SPARTAN-1 (Shuttle Pointed Autonomous Research Tool for AstroNomy) a deployable/retrievable carrier module, designed to be deployed from the orbiter and fly free in space before being retrieved. SPARTAN-1 included 140 kg (310 lb) of astronomy experiments. It was deployed and operated successfully, independent of the orbiter, before being retrieved. Discovery furthermore carried an experimental materials-processing furnace, two French biomedical experiments (French Echocardiograph Experiment (FEE) and French Postural Experiment (FPE)), [3] and six Getaway Special (GAS) experiments, which were all successfully performed, although the GO34 Getaway Special shut down prematurely. This mission was also the first flight test of the OEX advanced autopilot which gave the orbiter capabilities above and beyond those of the baseline system.
The mission's final payload element was a High Precision Tracking Experiment (HPTE) for the Strategic Defense Initiative (SDI) (nicknamed "Star Wars"); the HPTE failed to deploy properly during its first try on the mission's 37th orbit, because the orbiter was not at the correct attitude. It was successfully deployed on orbit 64.
Discovery landed at Edwards Air Force Base at 9:11:52 a.m. EDT on June 24, 1985, after a mission duration of 7 days, 1 hour, 38 minutes, and 52 seconds.
The STS-51-G insignia illustrates the advances in aviation technology in the United States within a relatively short span of the twentieth century with Discovery flying over the Wright Flyer . A gold-and-orange-flame eagle forms the base of the insigna. The surnames of the crewmembers for the Discovery's mission appear near the center edge of the circular design, with the French and Saudi crewmembers added below, with a respective flag icon along their name. Although Baudry was the first French citizen to fly with a Space Shuttle mission into space, he was only the second Frenchman to go to space, following Jean-Loup Chrétien's earlier missions with Soyuz capsule, Soyuz T-6.
NASA began a tradition of playing music to astronauts during Project Gemini, and first used music to wake up a flight crew during Apollo 15. Each track is specially chosen, often by the astronauts' families, and usually has a special meaning to an individual member of the crew, or is applicable to their daily activities. [4]

STS-41-D was the 12th flight of NASA's Space Shuttle program, and the first mission of Space Shuttle Discovery. It was launched from Kennedy Space Center, Florida, on August 30, 1984, and landed at Edwards Air Force Base, California, on September 5, 1984. Three commercial communications satellites were deployed into orbit during the six-day mission, and a number of scientific experiments were conducted, including a prototype extendable solar array that would eventually form the basis of the main solar arrays on the International Space Station (ISS).
STS-51-C was the 15th flight of NASA's Space Shuttle program, and the third flight of Space Shuttle Discovery. It launched on January 24, 1985, and made the fourth shuttle landing at the Shuttle Landing Facility at the Kennedy Space Center in Florida on January 27, 1985. STS-51-C was the first shuttle mission dedicated to the United States Department of Defense (DoD), and consequently many details remain classified. NASA reported that a satellite (USA-8) was deployed during the mission using an Inertial Upper Stage booster was deployed and met mission objectives. At just over three days, the mission was shorter in duration than most civilian missions and was the shortest of Discovery's career.
STS-51-D was the 16th flight of NASA's Space Shuttle program, and the fourth flight of Space Shuttle Discovery. The launch of STS-51-D from Kennedy Space Center (KSC), Florida, on April 12, 1985, was delayed by 55 minutes, after a boat strayed into the restricted Solid Rocket Booster (SRB) recovery zone. STS-51-D was the third shuttle mission to be extended.
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-63 was the second mission of the US/Russian Shuttle-Mir Program, which carried out the first rendezvous of the American Space Shuttle with Russia's space station Mir. Known as the 'Near-Mir' mission, the flight used Space Shuttle Discovery, which lifted off from launch pad 39B on February 3, 1995, from Kennedy Space Center, Florida. A night launch and the 20th mission for Discovery, it marked the first time a Space Shuttle mission had a female pilot, Eileen Collins, and the first EVAs for both a UK born astronaut, Michael Foale, and a US astronaut of African heritage, Bernard A. Harris, Jr. It also carried out the successful deployment and retrieval of the Spartan-204 platform, along with the scheduled rendezvous and flyaround of Mir, in preparation for STS-71, the first mission to dock with Mir.
STS-95 was a Space Shuttle mission launched from Kennedy Space Center, Florida on 29 October 1998, using the orbiter Discovery. It was the 25th flight of Discovery and the 92nd mission flown since the start of the Space Shuttle program in April 1981. It was a highly publicized mission due to former Project Mercury astronaut and United States Senator John H. Glenn Jr.'s return to space for his second space flight. At age 77, Glenn became the oldest person to go into space, a record that remained unbroken for 23 years until 82-year-old Wally Funk flew on a suborbital flight on Blue Origin NS-16, launching on 20 July 2021, which in turn was broken by William Shatner at age 90 on 13 October 2021 and then by Ed Dwight on May 19 2024. Glenn, however, remains the oldest person to reach Earth orbit. This mission is also noted for inaugurating ATSC HDTV broadcasting in the U.S., with live coast-to-coast coverage of the launch. In another first, Pedro Duque became the first Spaniard in space.
