Summary
STS-51 launched on a Lockheed Space Operations Company Space Shuttle from Launch Complex 39B, Kennedy Space Center, FL, USA on September 12, 1993. It was Lockheed Space Operations Company's 48th launch, 5th this year and humanity's 3,845th orbital launch attempt. It was the 57th Space Shuttle flight and the 5th this year. The payload was bound for low Earth orbit (LEO). Discovery (STS-51), one of 6 catalogued objects, reached a 303 × 311 km orbit inclined 28.5°. 5 crew members flew: Frank L. Culbertson Jr., William F. Readdy, Daniel W. Bursch, James H. Newman and Carl E. Walz. The spacecraft was Space Shuttle Discovery (OV-103). 6 objects from this launch are catalogued, 3 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: 9 days 20 hours
Space Shuttle Discovery successfully landed at the Shuttle Landing Facility after this mission.

About this launch
STS-51 was a Space Shuttle Discovery mission that launched the Advanced 10 Technology Satellite (ACTS) in September 1993. The flight also featured the deployment and retrieval of the SPAS-ORFEUS satellite and its IMAX camera, which captured spectacular footage of Discovery in space. A spacewalk was also performed during the mission to evaluate tools and techniques for the STS-61 Hubble Space Telescope servicing mission later that year.
