Launch of Soyuz 19 as part of the Apollo-Soyuz mission, based on the live TV broadcast. The degraded video images are supplemented with some film segments from the launch and mission photos. TV commentary missing segments were completed using NASA's audio reels.
Some earth views from onboard a modern Soyuz launch are used towards the end of launch. They roughly correspond to similar altitudes and flight stages to Soyuz 19, and were taken at a similar time of year.
The TV recording (original on lunarmodule5 channel: [ Ссылка ] ) was degraded and suffered from hue shifts that were corrected as best as possible. Some ambient audio from a modern Soyuz launch was used.
The Apollo–Soyuz Test Project (ASTP) (Russian: Экспериментальный полёт «Аполлон» – «Союз» (ЭПАС) conducted in July 1975, was the first joint U.S.–Soviet space flight.
The Apollo-Soyuz mission began at Baikonur Cosmodrome in Kazakhstan with the Soyuz 19 launch at July 15, 1975, carrying cosmonauts Alexey Leonov and Valery Kubasov. It was the first Soyuz launch to be broadcast live.
Hours later, Apollo followed, lifting off from NASA's Kennedy Space Center. On board were astronauts Thomas Stafford, Vance Brand and Donald Slayton.
The mission included both joint and separate scientific experiments, including an engineered eclipse of the Sun by Apollo to allow Soyuz to take photographs of the solar corona. The pre-flight work provided useful engineering experience for future joint US–Russian space flights, such as the Shuttle–Mir Program and the International Space Station. ASTP was the last crewed US space mission until the first Space Shuttle flight in April 1981.
