Summary
Apollo-Soyuz Test Project launched on a National Aeronautics and Space Administration Saturn IB from Launch Complex 39B, Kennedy Space Center, FL, USA on July 15, 1975. It was National Aeronautics and Space Administration's 129th launch, 2nd this year and humanity's 1,721st orbital launch attempt. It was the 10th Saturn IB flight and the 1st this year. The payload was bound for low Earth orbit (LEO). Apollo-Soyuz Test Project, one of 3 catalogued objects, reached a 160 × 174 km orbit inclined 51.8°. 3 crew members flew: Deke Slayton, Thomas P. Stafford and Vance D. Brand. The spacecraft was Apollo CSM-111 (CSM-111). 3 objects from this launch are catalogued, 2 of them payloads.

About this launch
The Apollo-Soyuz Test Project was the first joint US-Soviet space flight and the last crewed US space mission until the Space Shuttle program. The US side of mission began on July 15, 1975, 19:50:00 UTC, launching Commander Thomas P. Stafford, Command Module Pilot Vance D. Brand and Docking Module Pilot Donald K. Slayton into orbit. Two days later, they docked with the Soyuz 19 spacecraft. American and Soviet crews visited each other's spacecrafts, performed docking and redocking maneuvers, conducted joint scientific experiments, exchanged flags and gifts. Crews spent more than 44 hours together, and after final parting of the ships on July 19, Apollo crew spent nine more days in orbit, conducting Earth observation experiments. The Apollo crew returned to Earth on July 24, 1975, 21:18:0 UTC with a splashdown in the Pacific Ocean.
