Summary
STS-77 launched on a Lockheed Martin Space Operations Space Shuttle from Launch Complex 39B, Kennedy Space Center, FL, USA on May 19, 1996. It was Lockheed Martin Space Operations's 8th launch, 4th this year and humanity's 4,075th orbital launch attempt. It was the 77th Space Shuttle flight and the 4th this year. The payload was bound for low Earth orbit (LEO). Endeavour (STS-77), one of 4 catalogued objects, reached a 288 × 297 km orbit inclined 39.0°. 6 crew members flew: Marc Garneau, John Casper, Curtis Brown, Mario Runco Jr., Daniel W. Bursch and Andy Thomas. The spacecraft was Space Shuttle Endeavour (OV-105). 4 objects from this launch are catalogued, all of them payloads.

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: Low Earth Orbit
- Mission length: 10 days
Space Shuttle Endeavour successfully landed at the Shuttle Landing Facility after this mission.
