Summary
STS-134 launched on an United Space Alliance Space Shuttle from Launch Complex 39A, Kennedy Space Center, FL, USA on May 16, 2011. It was United Space Alliance's 50th launch, 2nd this year and humanity's 5,127th orbital launch attempt. It was the 134th Space Shuttle flight and the 2nd this year. The payload was bound for low Earth orbit (LEO). Endeavour (STS-134), one of 3 catalogued objects, reached a 238 × 332 km orbit inclined 51.6°. 6 crew members flew: Andrew J. Feustel, Roberto Vittori, Mark Kelly, Edward Michael Fincke, Gregory H. Johnson and Gregory Chamitoff. The spacecraft was Space Shuttle Endeavour (OV-105). 3 objects from this launch are catalogued, one of them a payload.

Spacecraft
Space Shuttle Endeavour (OV-105)
Space Shuttle Endeavour (Orbiter Vehicle Designation: OV-105) is a retired orbiter from NASA's Space Shuttle program and the fifth and final operational shuttle built. It embarked on its first mission, STS-49, in May 1992 and its 25th and final mission, STS-134, in May 2011. STS-134 was expected to be the final mission of the Space Shuttle program, but with the authorization of STS-135, Atlantis became the last shuttle to fly. The United States Congress approved the construction of Endeavour in 1987 to replace Challenger, which was lost in 1986. Structural spares built during the construction of Discovery and Atlantis were used in its assembly. NASA chose, on cost grounds, to build Endeavour from spares rather than refitting Enterprise.
- Destination: International Space Station
- Mission length: 15 days
- Docked May 18, 2011 at Harmony forward
Space Shuttle Endeavour successfully landed at the Shuttle Landing Facility after this mission.
