Summary
STS-51-G launched on a Lockheed Space Operations Company Space Shuttle from Launch Complex 39A, Kennedy Space Center, FL, USA on June 17, 1985. It was Lockheed Space Operations Company's 9th launch, 4th this year and humanity's 2,953rd orbital launch attempt. It was the 18th Space Shuttle flight and the 4th this year. The payload was bound for low Earth orbit (LEO). Discovery (STS 51-G), one of 8 catalogued objects, reached a 362 × 372 km orbit inclined 28.5°. 7 crew members flew: Patrick Baudry, Sultan bin Salman Al Saud, Daniel Brandenstein, John Oliver Creighton, Steven R. Nagel, John M. Fabian and Shannon Lucid. The spacecraft was Space Shuttle Discovery (OV-103). 8 objects from this launch are catalogued, 5 of them payloads.

Spacecraft
Space Shuttle Discovery (OV-103)
Space Shuttle Discovery (Orbiter Vehicle Designation: OV-103) is one of the orbiters from NASA's Space Shuttle program and the third of five fully operational orbiters to be built. Its first mission, STS-41-D, flew from August 30 to September 5, 1984. Over 27 years of service it launched and landed 39 times, gathering more spaceflights than any other spacecraft to date. Discovery became the third operational orbiter to enter service, preceded by Columbia and Challenger. It embarked on its last mission, STS-133, on February 24, 2011 and touched down for the final time at Kennedy Space Center on March 9, having spent a cumulative total of almost a full year in space. Discovery performed both research and International Space Station (ISS) assembly missions. It also carried the Hubble Space Telescope into orbit. Discovery was the first operational shuttle to be retired, followed by Endeavour and then Atlantis.
- Destination: Low Earth Orbit
- Mission length: 7 days 1 hour
Space Shuttle Discovery successfully landed at Edwards Air Force Base after this mission.

About this launch
STS-51-G was the eighteenth flight of the shuttle program and fifth for Space Shuttle Discovery. Sultan Salman Al Saud of Saudi Arabia was on board as a payload specialist; he became the first Arab, the first Muslim and first member of a royal family to fly into space. It was the first shuttle flight to fly without an astronaut from the pre-Shuttle era. Its mission was to deploy 3 10 satellites.
