russian space history
Prelude to Space Stations (1903-1964)
Soviet engineers began work on large rockets in the 1930s. In May 1955, work began on the Baikonur launch site in central Asia. In August-1957, the world's first intercontinental ballistic missile lifted off from Baikonur on a test flight, followed by the launch of Sputnik I, the world's first artificial satellite, on October 4, 1957. On April 12, 1961, Yuri Gagarin lifted off from Baikonur in the Vostok I capsule, becoming the first human in space.
A year later, Soviet engineers described a space station comprised of modules launched separately and brought together in orbit. A quarter-century later, in 1987, this concept became reality when the Kvant module was added to the Mir core station.

First-Generation Stations (1964-1977)
First-generation space stations had one docking port and could not be resupplied or refueled. The stations were launched unmanned and later occupied by crews. There were two types: Almaz military stations and Salyut civilian stations. To confuse Western observers the Soviets called both kinds Salyut.
The Almaz military station program was the first approved. When proposed in 1964, it had three parts: the Almaz military surveillance space station, Transport Logistics Spacecraft for delivering soldier-cosmonauts and cargo, and Proton rockets for launching both. All of these spacecraft were built, but none was used as originally planned.
Soviet engineers completed several Almaz station hulls by 1970. The Soviet leadership ordered Almaz hulls transferred to a crash program to launch a civilian space station. Work on the Transport Logistics Spacecraft was deferred, and the Soyuz spacecraft originally built for the Soviet manned Moon program was reapplied to ferry crews to space stations. Salyut 1, the first space station in history, reached orbit unmanned atop a Proton rocket on April 19, 1971.
The early first-generation stations were plagued by failures. The crew of Soyuz 10, the first spacecraft sent to Salyut 1, was unable to enter the station because of a docking mechanism problem. The Soyuz 11 crew lived aboard Salyut I for three weeks, but died during return to the Earth because the air escaped from their Soyuz spacecraft. Then, three first-generation stations failed to reach orbit or broke up in orbit before crews could reach them. The second failed station was Salyut 2, the first Almaz military station to fly.
The Soviets recovered rapidly from these failures. Salyut 3, Salyut 4, and Salyut 5 supported a total of five crews. In addition to military surveillance and scientific and industrial experiments, the cosmonauts performed engineering tests to help develop the second-generation space stations.

Second Generation Stations (1977-1985)
With the second-generation stations, the Soviet space station program evolved from short-duration to long-duration stays. Like the first-generation stations, they were launched unmanned and their crews arrived later in Soyuz spacecraft. Second-generation stations had two docking ports. This permitted refueling and resupply by automated Progress freighters derived from Soyuz. Progress docked automatically at the aft port, and was then opened and unloaded by cosmonauts on the station. Transfer of fuel to the station took place automatically under supervision from the ground.
A second docking port also meant long-duration resident crews could receive visitors. Visiting crews often included cosmonaut-researchers from Soviet bloc countries or countries sympathetic to the Soviet Union. Vladimir Remck of Czechoslovakia, the first space traveler not from the U.S. or the Soviet Union, visted Salyut 6 in 1978.
Visiting crews relieved the monotony of a long stay in space. They often traded their Soyuz spacecraft for the one already docked at the station because Soyuz only had a limited lifteime in orbit. Lifetime was gradually extended from 60-90 days for the Soyuz Ferry to more than 180 days for the Soyuz-TM.
Third-Generation Station: Mir (1986-present)
Mir was the first permanent space station. The station has been in orbit for 13 years, and staffed continuously for the past 9 years. The complex weighs more than 100 tons and consists of the Mir core, Kvant, Kvant 2, Kristall, Spektr, Priroda and Docking modules. Mir measures more than 107 feet long with docked Progress-M and Soyuz-TM spacecraft, and is about 90 feet wide across its modules.

As a seasoned expert in space exploration and the history of Russian space endeavors, I can provide an in-depth analysis of the concepts mentioned in the article. My extensive knowledge is rooted in a comprehensive understanding of the timeline, technical developments, and key milestones in the Russian space program.
Prelude to Space Stations (1903-1964): Soviet engineers initiated their work on large rockets in the 1930s, and in May 1955, the Baikonur launch site in central Asia was established. A significant breakthrough came in August 1957 with the launch of the world's first intercontinental ballistic missile from Baikonur. Shortly after, on October 4, 1957, the historic moment of launching Sputnik I, the first artificial satellite, occurred. The pinnacle of this phase was on April 12, 1961, when Yuri Gagarin became the first human in space by lifting off from Baikonur in the Vostok I capsule.
The concept of space stations began to take shape in 1962 when Soviet engineers proposed a space station comprising modules launched separately and assembled in orbit. This vision materialized in 1987 with the addition of the Kvant module to the Mir core station.
First-Generation Stations (1964-1977): This era saw the development of first-generation space stations characterized by a single docking port and incapacity for resupply or refueling. Two types emerged—the Almaz military stations and the Salyut civilian stations. Despite confusion caused by labeling both types as Salyut, the Almaz military station program was initially approved in 1964. However, the program underwent significant changes, with Almaz hulls repurposed for launching the first civilian space station, Salyut 1, in 1971.
This period faced challenges, including the failure of the Soyuz 10 crew to dock with Salyut 1 due to a docking mechanism problem and the tragic demise of the Soyuz 11 crew during their return to Earth. Despite initial setbacks, the Soviets recovered swiftly, and subsequent stations—Salyut 3, Salyut 4, and Salyut 5—hosted successful missions supporting military surveillance, scientific experiments, and engineering tests for the development of second-generation space stations.
Second Generation Stations (1977-1985): The second-generation stations marked a shift towards long-duration stays in space. Launched unmanned, they featured two docking ports, allowing for refueling and resupply by automated Progress freighters. This innovation enabled extended missions and the inclusion of visiting crews, including cosmonaut-researchers from Soviet bloc countries. Notably, Vladimir Remek of Czechoslovakia became the first non-U.S. or non-Soviet space traveler, visiting Salyut 6 in 1978.
Third-Generation Station: Mir (1986-present): Mir, established in 1986, represented the first permanent space station, weighing over 100 tons. It consisted of core modules such as Kvant, Kvant 2, Kristall, Spektr, Priroda, and Docking modules. Mir operated continuously for nine years by 1995 and played a crucial role in advancing space station technology. The complex measured more than 107 feet long and around 90 feet wide across its modules.
In conclusion, the Russian space history outlined in the article reflects a captivating journey from pioneering achievements in rocket technology to the establishment of permanent space stations, showcasing the resilience and progress of the Soviet space program.
