Summary
STS-56 launched on a Lockheed Space Operations Company Space Shuttle from Launch Complex 39B, Kennedy Space Center, FL, USA on April 8, 1993. It was Lockheed Space Operations Company's 45th launch, 2nd this year and humanity's 3,808th orbital launch attempt. It was the 54th Space Shuttle flight and the 2nd this year. The payload was bound for low Earth orbit (LEO). Discovery (STS-56), one of 2 catalogued objects, reached a 299 × 307 km orbit inclined 57.0°. 5 crew members flew: Kenneth D. Cameron, Stephen S. Oswald, Michael Foale, Kenneth Cockrell and Ellen Ochoa. The spacecraft was Space Shuttle Discovery (OV-103). 2 objects from this launch are catalogued, all 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 6 hours
Space Shuttle Discovery successfully landed at the Shuttle Landing Facility after this mission.
