Summary
STS-103 launched on a National Aeronautics and Space Administration Space Shuttle from Launch Complex 39A, Kennedy Space Center, FL, USA on December 20, 1999. It was National Aeronautics and Space Administration's 138th launch, 1st this year and humanity's 4,363rd orbital launch attempt. It was the 96th Space Shuttle flight and the 3rd this year. The payload was bound for low Earth orbit (LEO). It reached a 328 × 591 km orbit inclined 28.5°. 7 crew members flew: Claude Nicollier, Jean-François Clervoy, Curtis Brown, Michael Foale, John M. Grunsfeld, Steven Smith and Scott Kelly. The spacecraft was Space Shuttle Discovery (OV-103). One object from this launch is catalogued.

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 23 hours
- Docked December 22, 1999 at Hubble Space Telescope
Space Shuttle Discovery successfully landed at the Shuttle Landing Facility after this mission.
