The actual mission time was 5 days 22 hours. However, most of that time was spent in orbit, preparing for rendezvous and docking. Total time docked was 1 day 23 hours.
It was an aptly named program, as they used both Apollo and Soyuz vehicles. Apollo on the American side, and Soyuz on the Soviet side.
The Russian space program that linked with the American Apollo spacecraft in space in 1975 was the Soviet Soyuz program. This joint mission was known as the Apollo-Soyuz Test Project (ASTP) and symbolized the end of the Space Race between the United States and the Soviet Union.
The last lunar landing occurred in December, 1972. The Apollo-Soyuz Test Project, a non moon mission, where an American Apollo capsule docked with a Russion Soyuz Capsule, took place in 1975.
Apollo is the name of the American spacecraft and Soyuz is the name of the Russian spacecraft.
Directly following the end of the Apollo program was the Apollo Soyuz Test Program (ASTP) which, using Apollo flight hardware, performed the first international rendezvous and docking when the ASTP crew docked with a Russian Soyuz capsule. The next true program, one that required all new hardware, was the Shuttle Transport System, (STS). Also known as the Space Shuttle.
Apollo Soyuz in July 1975, involved the docking of an unnumbered Apollo Command/Service Module (a surplus one from the terminated Apollo moon program and the last to fly) with the Soviet Soyuz 19.
The astronauts of the Apollo-Soyuz mission did not land on the moon.
Apollo-Soyuz, made and activated after the phase-out of the Apollo program mated an Apollo command module (US) with a Soviet Soyuz spacecraft in orbit- both craft being manned, and this was sometimes called the summit in the sky. occured in l974 or 75. Do not confuse with Skylab, which used Apollo command modules as access craft.
The Apollo-Soyuz mission flew in July, 1975.
The mission following the end of the Apollo program was the Apollo Soyuz Test Project, or ASTP. This program was the first joint US / Russia space mission. It entailed Apollo hardware rendezvousing and docking with Soyuz hardware while in orbit. This mission, however, also used most of the same hardware designed for the moon landings. The next new-hardware mission post Apollo was the Space Transport System or STS, better known as the Space Shuttle.
Apollo-Soyuz A+
Apollo was the Greco_Roman sun god. Most Nasa missions drew names from Classical mythology, this being no exception. Apollo program was the manned Lunar Program and some predecessors and left-overs- Apollo Command modules were used in the Skylab and Apollo-Soyuz project which were strictly Earth-Orbital.
