Human Spaceflight Timeline: Apollo/Soyuz 

The final mission of the Apollo program was docking in space with a Russian Soyuz capsule. In July 1975 three Americans in an Apollo craft and two Russians in a Soyuz capsule conducted joint activities for nearly two days. Thomas P. Stafford, Vance D. Brand and Donald K. Slayton were the three American astronauts and the Cosmonauts were Alexey A. Leonov and Valery N. Kubasov.

Both craft were launched on July 15, 1975. Rendezvous occurred at 12:12pm (EDT) July 17, 1974. The crews exchanged commemorative flags and other gifts on live television. Though many people felt this mission only served a public relations role, there were a number of technological breakthroughs. The most important was the knowledge gained from docking two completely different spacecraft, each with unique atmospheric conditions.

More importantly, the mission opened the door to future cooperation between the Soviet Union (Russia) and the United States. Much was learned about what would be necessary in order for astronauts and cosmonauts to work together in space. The language barrier was a key issue. It was learned that the best arrangement was for the Americans to speak Russian and the Russians to speak English.

Even though it would be six years before Americans would return to space aboard the Space Shuttle, Apollo-Soyuz set the tone for the future of human space exploration. American astronauts have since gained invaluable knowledge by living on the Mir Space Station and Russians will be essential in the building and running of the ISS.
