Space Station Early History

Space Station Concepts First concepts of manned orbital stations began as fictional stories that are the roots of science fiction Sir Edward Everet Hale wrote of an orbiting sphere in the 1860s that carried construction crew and families in a satellite made of bricks Sir Edward Everet Hale wrote of an orbiting sphere in the 1860s that carried construction crew and families in a satellite made of bricks The Brick Moon published in Harper’s magazine in 1869 The Brick Moon published in Harper’s magazine in 1869 Communications was by Morse code with inhabitants jumping up and down Communications was by Morse code with inhabitants jumping up and down

Space Station Concepts First realistic concepts came from the Russian space pioneer Konstatin Tsiolovsky in the early 1900s Orbiting ring-shaped station was a transition for exploration of the solar system Orbiting ring-shaped station was a transition for exploration of the solar system Liquid fuel launch vehicles, solar power, space suits, airlocks, plant growth, satellite launches were introduced for the first time in his works Liquid fuel launch vehicles, solar power, space suits, airlocks, plant growth, satellite launches were introduced for the first time in his works

Space Station Concepts Hermann Oberth proposed an orbiting station in 1923 in his publication The Rocket into Interplanetary Space (Die Rakete zu den Planetenraumen) Oberth’s station concept consisted of descriptive remarks on its function Oberth’s station concept consisted of descriptive remarks on its function Earth observation Earth observation Communications link Communications link Weather observations Weather observations Orbital refueling station for interplanetary flight Orbital refueling station for interplanetary flight

Space Station Concepts The first engineering concepts of a station were introduced by Herman Nordlung Design described in his 1929 publication The Problem of Space Travel: The Rocket Motor Design described in his 1929 publication The Problem of Space Travel: The Rocket Motor Basic structure was a 50 m rotating wheel platform with solar concentrator for generating power (solar powered) Basic structure was a 50 m rotating wheel platform with solar concentrator for generating power (solar powered) Served as an observatory for celestial and earth observations, and a communications link Served as an observatory for celestial and earth observations, and a communications link Geostationary orbit would have required a huge booster Geostationary orbit would have required a huge booster

International Space Station Collapse of the Soviet Union in 1991 presented both Russia and the U.S. with major cooperative space opportunities Russia had little or no money to continue their Mir space station project and other space programs Russia had little or no money to continue their Mir space station project and other space programs The U.S. could benefit from Russia’s vast experience in space station operations to enhance its SSF project The U.S. could benefit from Russia’s vast experience in space station operations to enhance its SSF project Proposals were made in 1992/1993 to combine space station efforts, including the SSF international partners Proposals were made in 1992/1993 to combine space station efforts, including the SSF international partners These agreements were the birth of the International Space Station Alpha These agreements were the birth of the International Space Station Alpha

Space Station Freedom

International Space Station The International Space Station was a combined effort of the United States, Russia, and more than a dozen international partners Fused Russia's second generation Mir space station with the U.S. Space Station Freedom Originally called Space Station Alpha, the orbital facility reduced costs and multiplied the capabilities of both designs The ISS was conceived in the late 1980's with hardware being fabricated as early as the mid 1990's Much of the design and hardware of the Space Station Alpha has been incorporated into the International Space Station, with the first element launched in November, 1998
